Answer:

8 vehicle.

Step-by-step explanation:

Given: Monthly salary of salesperson is $2400

          Incentive of salesperson is $250 per vehicle sold.

First, lets compute income to earned apart from salary.

∴ Deduct salary from the target amount

[tex]\$ 4400-\$ 2400= \$ 2000[/tex]

∴ $2000 need to be earned only through incentive, which is $250 per vehicle sold.

Now, solving to get number vehicles to be sold to earn $2000 as incentive.

Number of vehicle= [tex]\frac{2000}{250}= 8\ vehicles[/tex]

∴ 8 vehicles need to be sold by salesperson to get total earning as $4400.

The salesperson needs to sell 8 vehicles to earn a total of $4400 in a month.

To determine the number of vehicles a salesperson needs to sell to earn a total of $4400, we can set up an equation based on the information provided.

The salesperson earns a fixed monthly salary of $2400 and an additional $250 for each vehicle sold. Let's denote the number of vehicles sold as x

We want the total earnings  E to be $4400, so we set up the equation:

 4400 = 2400 + 250x

Now, we solve for x

250x = 4400 - 2400

x= 8

 Therefore, the salesperson needs to sell 8 vehicles to earn a total of $4400 in a month.

Answer:

35 hotdogs and 52 sodas were sold.

Step-by-step explanation:

Create equations to represent the problem.

let "d" be the number of hotdogs sold

let "a" be the number of sodas sold

1.5d + 0.5a = 78.50     Equation for money made

d + a = 87                    Equation for items sold

Rearrange d + a = 87 to isolate one of the variables.

a = 87 - d

Substitute a for 87-d into the other equation. Isolate using reverse operations.

1.5d + 0.5a = 78.50

1.5d + 0.5(87 - d) = 78.50     Distribute over brackets by multiplying

1.5d + 43.5 - 0.5d = 78.50    Collect like terms

43.5 + d = 78.50          1.5d - 0.5d is 1d. You don't need to write "1".

43.5 + d - 43.5 = 78.50 - 43.5   Isolate d, subtract 43.5 from both sides

d = 35    Number of hotdogs sold

Substitute d for 35 in the simpler equation

d + a = 87

35 + a = 87     Subtract 35 form both sides to isolate "a".

a = 87 - 35

a = 52      Number of sodas sold

Therefore 35 hotdogs and 52 sodas were sold.

Let's solve this problem step by step.
1. We are given the total number of hippos, which is 3.
2. We are also given the total number of pumpkins, which is 5.
3. We want to find out how many pumpkins each hippo gets if the pumpkins are distributed evenly among the hippos.
To find out the number of pumpkins per hippo, we divide the total number of pumpkins by the total number of hippos.
4. Performing the division, we have:
  \( \frac{5 \, \text{pumpkins}}{3 \, \text{hippos}} = 1.666... \)
5. Each hippo gets approximately 1.666... pumpkins.
To express the number with a finite number of decimal places, we can round it to the desired precision. For example, rounding to two decimal places, we get 1.67 pumpkins per hippo. This is a simplification, as the fraction actually represents a repeating decimal with the digit 6 repeating indefinitely (i.e., 1.\(\overline{6}\) pumpkins per hippo).

Answer:

Choice B and Choise C.

Step-by-step explanation:

Equivalent expressions are those expressions that have the same value but they look different.

Given the following expression provided in the exercise:

[tex]6.53 - (-4.11) + 7.92[/tex]

You need to remember the multiplication of signs in order to find the equivalent expressions:

[tex](+)(+)=+\\(-)(-)=+\\(-)(+)=-\\(+)(-)=-[/tex]

Then:

- Eliminating the parentheses, you get this equivalent expression:

[tex]6.53 +4.11 + 7.92[/tex]

- Since the mulplication of two negative signs gives yous a positive sign, you can rewrite the original expression in this form:

[tex]-(-6.53)+4.11-(-7.92)[/tex]

This is an equivalent expression to [tex]6.53 - (-4.11) + 7.92[/tex]

Answer:

The Radius of circle is 7.15 cm  

Step-by-step explanation:

Given as :

A Triangle is inscribed into circle

The center of circle is O

The Diameter of circle = AK = d

The hypotenuse of triangle being the diameter of circle

The Area of triangle = 50 cm²

Let The radius of circle = r cm

The Triangle is right angle at c

So , ∠ACK = 90°

∠CAK = 42°

∠AKC = 180° - (90° + 42°)

So, ∠AKC = 48°

Now, ∵ Area of triangle ACK = 50 cm²

So, [tex]\dfrac{1}{2}[/tex] × AC × CK = 50

Or, AC × CK = 50 × 2

i.e , AC × CK = 100        ..........1

From figure

Sin 48° =  [tex]\dfrac{AC}{AK}[/tex]

Or, 0.74 =  [tex]\dfrac{AC}{d}[/tex]

∴ AC = 0.74 d             ..........2

Similarly

Sin 42° =  [tex]\dfrac{CK}{AK}[/tex]

Or, 0.66 =  [tex]\dfrac{CK}{d}[/tex]

∴ CK = 0.66 d               .............3

Putting eq 2 and 3 value into eq 1

i.e  AC × CK = 100  

Or, 0.74 d  × 0.66 d = 100  

Or, 0.4884 × d² = 100  

∴ d² = [tex]\dfrac{100}{0.4884}[/tex]

Or, d² = 204.75

Or, d = [tex]\sqrt{204.75}[/tex]

Or, d = 14.30

So, The diameter of circle = d = 14.30 cm

Now, Radius of circle = [tex]\dfrac{\textrm diameter}{2}[/tex]

Or, r =  [tex]\dfrac{\textrm 14.30 cm}{2}[/tex]

i.e r = 7.15 cm

So, The Radius of circle =  r = 7.15 cm

Hence, The Radius of circle is 7.15 cm  Answer

The house would be approximately 10.91 inches tall on the blueprint to represent a 20-foot actual height.

The student asked how many inches high a house would be on a blueprint if the actual home is to be 20 feet tall, and a blueprint states that a 6-inch line represents 11 feet on the actual home. To solve this, we set up a proportion to determine the blueprint's height. The proportion is 6 inches/11 feet = x inches/20 feet, where x represents the height on the blueprint. First, write the proportion as 6 inches/11 feet = x inches/20 feet. Then, cross-multiply to get 11 feet * x inches = 6 inches * 20 feet. To find x, divide both sides of the equation by 11 feet, getting x = (6 inches * 20 feet) / 11 feet. After calculating, we find that x ≈ 10.91 inches. Therefore, on the blueprint, the house would be approximately 10.91 inches tall to represent an actual height of 20 feet.

Answer:

Step-by-step explanation:

marked down by 1/4 of the original price.

let x represent original price

original price - 1/4 of original price = sales price

x - 1/4x = 128

4/4x - 1/4x = 128

3/4x = 128

x = 128/(3/4)

x = 128 * 4/3

x = 512/3

x = 170.666 rounds to 170.67 <== original price

==============================

I hope I am understanding this one correctly...

let x = price the store paid

x + 1/2x = 170.67

2/2x + 1/2x = 170.67

3/2x = 170.67

x = 170.67 / (3/2)

x = 170.67 * 2/3

x = 341.34/3

x = 113.78 <=== what the store paid

===========================

the difference between the discount price..I am assuming this is the $ 128 from part A.....and what the store paid....113.78...from part B..

128 - 113.78 = $ 14.22 <==

The unit price per pair of insulated gloves is found by dividing the total cost of the package by the number of pairs. For a package costing $35.34 containing 6 pairs of gloves, the unit price is $5.89 per pair.

The question asks us to calculate the unit price of a pair of insulated gloves when given the total cost for a package containing multiple pairs. To find the unit price, you would divide the total cost of the package by the number of units (pairs of gloves) in the package. If a package of 6 pairs of gloves costs $35.34, then the unit price per pair of gloves is calculated as follows:

Total cost of package: $35.34

Number of pairs in the package: 6

The unit price per pair of gloves = Total cost of package
/ Number of pairs

Unit price per pair of gloves = $35.34 / 6

Calculating this, we get the unit price per pair of gloves:

Unit price per pair of gloves = $5.89

The measure of arc AC is [tex]136^o[/tex]

Step-by-step explanation:

Notice that angle BAC (whose measure is given as 34 degrees) is an inscribed angle, and according toe the inscribed angle theorem, the measure of an inscribed angle is half the measure of the central angle that subtends the same chord.

Then, the central angle that subtends the cord BC, is twice 34 degrees ([tex]2\,*\,34^o = 68^o[/tex])

Then, since they give us also the measure of the arc AB which is [tex]156^o[/tex], then the measure of arc AC can be estimated as the needed measure to complete [tex]360^o[/tex] as the sum of all three arcs. That is:

[tex]AC + AB+ BC = 360^o\\AC + 156^o+2\,*\,34^o = 360^o\\AC + 156^o+68^o = 360^o\\AC=360^o-156^o-68^o\\AC=136^o[/tex]

The Total cost of 2 coats of paint in the room is 73.508 pounds

Step-by-step explanation:

Given as :

The length of the room = L = 6.8 meters

The breadth of the room = B = 9.2 meters

The cost of paint to cover 20 meters² area = 11.75 pounds

Let The cost painting the room = x pounds

Now, According to question

The Area of rectangular room = Length × breadth

Or, Area = L×B

Or, A = 6.8 meters × 9.2 meters

Or, Area = 62.56 meters²

∵ cost of paint to cover 20 meters² area = 11.75 pounds

∴ cost of paint to cover 62.56 meters² area = [tex]\dfrac{11.75}{20}[/tex] × 62.56 pounds

Or, x = 0.5875 × 62.56 pounds

Or, x = 36.754 pounds

So, cost painting the room = x = 36.754 pounds

Now, Since 2 coats of paints is allowed in the room

And The cost of 1 coats of paints = 36.754 pounds

So, The cost of 2 coats of paints = 36.754 × 2 pounds

i.e The cost of 2 coats of paints = 73.508 pounds

Hence, The cost of 2 coats of paint in the room is 73.508 pounds Answer

Answer: 2 bookcases.

Step-by-step explanation:

Let be "x" the number of bookcases that the custodian will be able to repaint completly with 5 gallons of paint.

According to the data given, the custodian needs 2 gallons of paint to repaint one bookcase. Since all the bookcases are equal, you can set up the following proportion:

[tex]\frac{2}{1}=\frac{5}{x}[/tex]

Now you must solve for "x" in order to find its value:

[tex](x)(\frac{2}{1})=5\\\\2x=5\\\\x=\frac{5}{2}\\\\x=2.5[/tex]

Notice that the custodian will be able to repaint 2 bookcases completely, then you can say that:

[tex]x\approx2[/tex]

The custodian will be able to repaint 2 bookcases with 5 gallons of paint.

To determine the number of bookcases the custodian will be able to repaint with 5 gallons of paint, we need to divide the total amount of paint by the amount of paint required for each bookcase. Each bookcase requires 2 gallons of paint, so we divide 5 gallons by 2 gallons per bookcase:

5 gallons ÷ 2 gallons/bookcase = 2.5 bookcases

Since we cannot have 0.5 of a bookcase, the custodian will be able to repaint 2 bookcases with 5 gallons of paint.
