Answer:

He will earn 13.91 after his raise.

Step-by-step explanation:

13 x .07 = .91

13.00 + .91 = 13.91

The amount Curtis earns per hour after his raise is 13 * (1 + 7%)

From the question, we have the following parameters that can be used in our computation:

Initial = $13

Raise =7%

using the above as a guide, we have the following:

New = Initial * (1 + raise)

So, we have

New = 13 * (1 + 7%)

Hence, the expression is 13 * (1 + 7%)

Answer:

The hourly rate of pay for:

Jude =$5 an hour

Ben = $4 an hour

Step-by-step explanation:

Let x represents Judy and y represents Ben.

As per the statement:Judy worked 8 hours and Ben worked 10 hours. Their combined pay was $80.

⇒[tex]8x + 10y =80[/tex]                     ......[1]

Also, it is given that When Judy worked 9 hours and Ben worked 5 hours, their combined pay was $65.

⇒[tex]9x+5y=65[/tex]                         .....[2]

Multiply equation [2] by 2 both sides we get;

[tex]2(9x+5y)=2 \cdot65[/tex]

18x + 10y = 130                                      .....[3]

Subtract [2] from [3] to eliminate y and solve for x;

18x + 10y -8x -10y = 130 -80

Simplify:

10x = 50

Divide both sides by 10 we get;

x = 5

⇒ Judy gets paid $5 an hour

Substitute value of x in [1] we get;

8(5) + 10y = 80

40 + 10y = 80

Subtract 40 from both sides we get;

40 + 10y - 40 = 80 -40

Simplify:

10 y = 40

Divide both sides by 10 we get;

y = 4

⇒Ben gets paid $4 an hour

Answer:

y = x + 20

Step-by-step explanation:

Isolate the variable you are solving for, y. Note the equal sign, what you do to one side, you do to the other. Add 20 to both sides

x (+20) = y - 20 (+20)

y = x + 20

y = x + 20 is your answer

Answer: Y= x+20

Step-by-step explanation: x = y-20, you must first add 20 to both sides to get Y on its own. So x+20 = y - 20 + 20, the twenties cancel each other out giving us x+20 = y or y=x+20

The answer is B. 80.8

Answer:

The average of the whole class is 80.8.

The correct answer is B)

Step-by-step explanation:

To solve this problem, it is very important to understand the phrase: "Ten students had an average of 88". Let's see an example.

Imagine that three students in the class took a test and their scores were: 80, 89 and 95. To calculate the average of they three we must divide the sum of the scores by the total number of scores.

[tex]average=\frac{80+89+95}{3}=\frac{264}{3}=88[/tex]

The previous value is the average of the three students. Now, if we say that each student got 88, the average would be 88.

[tex]average=\frac{88+88+88}{3}=\frac{264}{3}=88[/tex]

The previous expression could be simplified as:

[tex]average=\frac{88\times 3}{3}[/tex]

Where, the number 3 means the number of students.

With that in mind, the phrase "Ten students had an average of 88" could be written as:

[tex]average_{10\, \, students}=\frac{88+88+88+88+88+88+88+88+88+88}{10}[/tex]

[tex]average_{10\, \, students}=\frac{88\times 10}{10}=88[/tex]

On the other hand, the phrase "The other students had an average of 76" means that from the 25 students, 15 students got 76 (25 - 10 = 15), and could be written as:

[tex]average_{15\, \, students}=\frac{76+76+76+76+76+76+76+76+76+76+76+76+76+76+76}{15}[/tex]

[tex]average_{15\, \, students}=\frac{76\times 15}{15}=76[/tex]

Finally, to calculate the total average of the 25 students we must divide the sum of the scores of all students by the total number of scores. The sum would be: 88+88+88+88+88+88+88+88+88+88+76+76+76+76+76+76+76+76+76+76+76+76+76+76+76, which equals [tex]88\times 10+76\times 15[/tex]. The total number of scores would be: 25.

[tex]average_{total}=\frac{88\times 10 + 76\times 15}{25}[/tex]

[tex]average_{total}=\frac{880 + 1140}{25}[/tex]

[tex]average_{total}=\frac{880 + 1140}{25}[/tex]

[tex]average_{total}=\frac{2020}{25}[/tex]

[tex]average_{total}=80.8[/tex]

Thus, the average of the whole class is 80.8. The correct answer is B)

Step-by-step explanation:

We know the tops 2 parts of the kite have to be equal

x+3 = 15

Subtract 3 from each side

x+3-3 =15-3

x=12

We also know the bottoms have to be equal

3y-1 =2x-4

Substitute the value for x

3y-1 =2(12) -4

3y-1 =24-4

3y-1 =20

Add 1 to each side

3y-1+1 =20+1

3y = 21

Divide each side by 3

3y/3 = 21/3

y = 7

Answer:

15.4 gallons .

Step-by-step explanation:

The rate of gas used  = 380/14 = 27.14 gallons per gallon.

So for each gallon used  you drive 27.14 miles.

So number of gallons used when travelling 418 miles = 418/27.14

= 15.4 gallons .

At the rate your car consumes gas, you will need 15.4 gallons to drive 418 miles.

The first thing to do here is to find out how many miles you can go with a single gallon of gas.

= Gas used / Number of miles traveled

= 14 / 380

= 0.0368 gallons per mile

Now that you have to drive 418 miles, the amount of gas you will need is:

= Number of miles to travel gas per mile

= 418 x 0.0368

= 15.4 gallons

In conclusion, you will need 15.4 gallons.

Answer

  [tex]y = -3x^2-4x+3[/tex]

Explanation

The standard form of a parabola is

  [tex]y = ax^2 + bx + c,[/tex]

where [tex]a \ne 0[/tex], and [tex]a,b,c[/tex] are real numbers.

If it passes through (0,3) then when x = 0, y = 3 so this means that

  [tex]3 = a(0)^2 + b(0) + c \implies c = 3[/tex]

so [tex]y = ax^2 + bx + 3[/tex].

If it passes through (1,-4), then when x = 1, y = -4 so

  [tex]\begin{aligned}-4 &= a(1)^2 + b(1) + 3 \\a+b+3 &= -4 \\a+b &= -7 && \text{(I).}\end{aligned}[/tex]

If it passes through (-1,4) then when x = -1, y = 4 so

  [tex]\begin{aligned}4 &= a(-1)^2 + b(-1) + 3 \\a-b+3 &= 4 \\a-b &= 1 && \text{(II).}\end{aligned}[/tex]

Because both (I) and (II) need to be satisfied, we have the system of equations,

  [tex]\begin{cases}a+b &= -7\qquad\text{(I)}\\a-b &= 1\qquad\text{(II)}\end{cases}[/tex]

which we can easily solve by adding the two equations up to get

  [tex]\begin{aligned}(a+a) + (b-b) &= -7 + 1 \\ 2a&= -6 \\a &= -3.\end{aligned}[/tex]

Then we take any of the previous equations to solve for b:

  [tex]\begin{aligned}a+b &= -7\\-3 + b &= -7 \\ b &= -4\end{aligned}[/tex]

Thus the parabola in standard form is

  [tex]y = -3x^2-4x+3.[/tex]

So with the three points that are given to us, we will plug them into the standard form formula that I had mentioned earlier. Firstly, plug (0,3) into the equation since the 0 will cancel out the a and b variable:

[tex]3=a*0^2+b*0+c\\3=c[/tex]

Now we know that the value of c is 3.

Next, plug (1,-4) into the standard form formula and simplify (Remember to plug 3 into the c variable):

[tex]-4=a*1^2+1*b+3\\-4=a+b+3\\-7=a+b[/tex]

Next, plug (-1,4) into the standard form formula and simplify:

[tex]4=a*(-1)^2+b*(-1)+3\\4=a-b+3\\1=a-b[/tex]

With the last two simplified equations, we will create a system of equations:

[tex]-7=a+b\\1=a-b[/tex]

With this, I will be using the elimination method. Add the two equations together, and the following equation is the result:

[tex]-6=2a[/tex]

From here we can solve for a. For this, just divide both sides by 2:

[tex]-3=a[/tex]

Now that we have the value of a, plug it into either equation to solve for b:

[tex]-7=-3+b\\-4=b\\\\1=-3-b\\4=-b\\-4=b[/tex]

Now, plug the obtained values in our standard form equation and your final answer will be:

[tex]y=-3x^2-4x+3[/tex]

Answer: 3996 meters

Step-by-step explanation:

Given: Maya is camping at the top of mount armstrong at an elevation of 7832 meters.

Consider the pont of sea level be 0.

Then the  height of the point where Mary is = +7832 meters (by using integers)

Juan is scuba diving 160 meters below sea level.

⇒The height of the point where Juan is =-160 meters

The distance between them =[tex]7832-(-160)=7832+160=7992\ meters[/tex]

The mid point of the distance= [tex]\frac{1}{2}\times7992=3996\ meters[/tex]

Hence, Maya & Juan meet will meet at an elevation of 3996 meters .

Final answer:

Maya and Juan will meet at an elevation of 3836 meters.

Explanation:

To find the elevation at which Maya and Juan will meet, we need to calculate the average of their elevations. Maya is at an elevation of 7832 meters and Juan is at an elevation 160 meters below sea level. The average of these two elevations is:

Average = (7832 + (-160)) / 2 = 3836 meters.

Therefore, Maya and Juan will meet at an elevation of 3836 meters.

Answer: 31 nickels and 29 dimes

Step-by-step explanation:

Nickels (.05): x

Dimes (.10): y

 Value:     .05x + .10y = 4.45 →  -20(.05x + .10y = 4.45)   →   -x - 2y = -89

Quantity:        x  +    y  = 60   →       1(x  +    y  = 60)           →   x  + y = 60

                                                                                                       -y  = -29

                                                                                                        y  =  29

Next, substitute "29" for "y" into either equation and solve for "x":

x +  y  = 60

x + 29 = 60

x          = 31

The number of nickels and dimes that are in the jar is 31 and 29 respectively.

Given that,

Based on the above information, the calculation is as follows:

x + y = 60 ........(1)

5x + 10y = 445.......(2)

Here we multiply by 5 in equation 1

5x + 5y = 300

5x + 10y = 445

-5y = 145

y = 29

So, x = 60 - 29

= 31

Therefore we can conclude that the number of nickels and dimes that are in the jar is 31 and 29 respectively.

35% off, deducts $15.05

Step-by-step explanation:

The sale price was $27.95 and is 65% of the original price. This means the sale was 100%-65%= 35% off the original price.

We can create a proportion to find the original price to see how much was deducted. A proportion is an equation where two ratios are set equal to each other. We create two fractions using the prices and percents.

[tex]\frac{27.95}{x} =\frac{65}{100}[/tex]

We begin solving by cross multiplying numerator to denominator of each fraction.

[tex]27.95(100)=65(x)\\2795=65x\\\frac{2795}{65}=\frac{65x}{65}  \\43=x[/tex]

So the original price was $43. The sale price deducts 43-27.95= 15.05
