Answer:
23 hoursStep-by-step explanation:
To solve, we need to substitute into the given equation:
T = d/a − j + d/a + j
T = 2468/510 (-115 + 2468/510 + 115)
T = 4.83921568627 (-115 + 4.83921568627 + 115)
T = 23.4180084582
Approx: 23 hours
I'm always happy to help :)
Answer:
10.2
Step-by-step explanation:
ok so simplified your equation is [tex]T=\frac{2da}{(a+j)(a-j)}[/tex] so you plug in your numbers.
[tex]T=\frac{2(2468)(510)}{(510+115)(510-115)}[/tex] after adding 510 and 115 you get 625 but both 510 and 625 are divisible by 5 so divide each by 5. you should have:
[tex]T=\frac{2(2468)(102)}{(125)(395)}[/tex] so just solve basically. [tex]T=\frac{503472}{49375}[/tex] it comes out to 10.196 but after some rounding its 10.2

Convert the polar equation r = 2 costheta in Cartesian equation form.
Answer:
To transform from polar coordinates into Cartesian coordinates we have:
x = r x cos(theta)
y = r x sin(theta)
r^2 = x^2 + y^2
=> r = 2*cos(theta)
<=> r = 2*(x/r)
<=> 2x = r^2
<=> 2x = x^2 + y^2
Hope this helps!
:)
Answer:
x² + y² - 2x = 0
Step-by-step explanation:
r = sqrt(x² + y²)
x = r cos(theta)
r = 2 cos(theta)
Multiply both sides by r
r² = 2r cos(theta)
x² + y² = 2x

What is the radius and diameter of the following circle?
14 cm
Radius
cm
Diameter
cm
Answer:
Radius = 7cm
Diameter = 14cm
Step-by-step explanation:
Radius is a straight line that connects the center of a circle to a point on the circumference (outside of the circle).
Diameter is a straight line that goes through the center of a circle and connects two points on the circumference (outside of the circle).
The line shown goes across the entire circle, so it is the diameter
Diameter = 14 m
The radius of a circle is half the length of the diameter.
r = [tex]\frac{d}{2}[/tex]
r = [tex]\frac{14}{2}[/tex]
r = 7 cm
This is why the radius is 7cm, and the diameter is 14cm.
Hope this helped!
Question 7

Assuming that the Earth is a sphere of radius 4000 miles, find the
distance between the following two cities whose latitudes are given.
You may assume that these cities are on the same basic longitude.
Cincinnati, Ohio (39° 8' 46" N) and Huntsville, Alabama (34° 43'41"N)
Next >
Answer:
308.4miles
Step-by-step explanation:
Given that radius of earth= 4000miles
Change in latitude = 39° 8' 46" - 34° 43'41"
= 4° 25' 5"
= 4+25/60+5/3600
4+0.4166+0.00138
θ = 4.417°
Converting to radian = 4.417°×π÷180
= 4.417×0.0174
= 0.07710
Distance between the cities = rθ
S = 4000×0.07710
S= 308.4miles
Final answer:
The distance between Cincinnati, Ohio and Huntsville, Alabama is calculated by first converting their latitudes to radians, finding the difference, and then using the arc length formula on a sphere (assuming both cities are on the same longitude). The estimated distance is approximately 308 miles.
Explanation:
The question is asking to calculate the distance between Cincinnati, Ohio and Huntsville, Alabama, assuming the Earth is a sphere with a radius of 4000 miles and that both cities are on the same longitude. To calculate the distance, we first convert the latitudinal degrees to radians and then use the formula for arc length on a sphere, which is:
Arc Length = radius times (latitude1 - latitude2)
Firstly, convert the latitudes from degrees, minutes, and seconds to decimal degrees:
Cincinnati, Ohio: 39 degrees, 8 minutes, 46 seconds N = 39 + (8/60) + (46/3600) = 39.1461° NHuntsville, Alabama: 34 degrees, 43 minutes, 41 seconds N = 34 + (43/60) + (41/3600) = 34.7281° NThen, convert the decimal degrees to radians:
Cincinnati: 39.1461° times (π/180) = 0.6832 radHuntsville: 34.7281° times (π/180) = 0.6062 radCalculate the difference in latitude in radians:
Difference in latitude = 0.6832 rad - 0.6062 rad = 0.077 rad
Finally, use the arc length formula:
Arc length = 4000 miles times 0.077 rad = 308 miles
Therefore, the distance between Cincinnati, Ohio, and Huntsville, Alabama, is approximately 308 miles.

What is algebraic Expression?Any mathematical statement that includes numbers, variables, and an arithmetic operation between them is known as an expression or algebraic expression. In the phrase 4m + 5, for instance, the terms 4m and 5 are separated from the variable m by the arithmetic sign +.
To solve for x in equation 5x - 3 = 12, we need to isolate x on one side of the equation.
First, we can add 3 to both sides of the equation:
5x - 3 + 3 = 12 + 3
Simplifying the left-hand side:
5x = 15
Next, we can divide both sides of the equation by 5:
5x/5 = 15/5
Simplifying the left-hand side:
x = 3
Therefore, the solution to the equation 5x - 3 = 12 is x = 3.

Keesha bought 11 binders and notebooks
from the store and spent $45. Binders cost
$6 each and notebooks cost $2.50 each. Which
two equations can be used to find the number
of binders, b, and notebooks, 11, she purchased?
Answer:
sssssssss
Step-by-step explanation:
Given,
Keesha bought = x binder.
Let Keesha bought (11-x) notebook.
Total money spent = $45
Cost of each binder = $ 6
Cost of each notebook = $ 2.50
Now,
Equation
$ 6 × x + $ 2.50 × (11-x) = $ 45
$ 6 x + $27.5 - $ 2.50 x= $ 45
$ 3.50 x = $ 17.5
x = 5
Number of binder = 5.
Number of cover = 11-5 = 6.
Final answer:
The two equations to determine the number of binders (b) and notebooks (n) Keesha purchased are: b + n = 11 and 6b + 2.50n = 45. These equations are based on the total number of items and the total cost of the items.
Explanation:
To determine the number of binders and notebooks Keesha purchased, we need to set up two equations based on the given information. The first equation will represent the total number of items purchased, and the second will represent the total cost of those items.
Equation 1 (total number of items):
b + n = 11
Equation 2 (total cost):
$6 × b + $2.50 × n = $45
In the above equations, b represents the number of binders and n represents the number of notebooks. These two equations can be used to solve for the variables b and n using methods such as substitution or elimination.
One month Jane rented 5 movies and video games for a total of .$34 The next month she rented 2 movies and video games for a total of .$73 Find the rental cost for each movie and each video game.
Answer: each movie costs $6.80, each game costs $29.7
Step-by-step explanation:
First to find the movie cost i divided 34/5, and it gave me an answer of 6.80, then i multiplied 6.80 by 2 because it said you bought 2 movies along with 2 video games, 6.80 times 2 is 13.6. afterwards i subtracted, 73-13.6, my answer was 59.4, later i divided that by 2, and each game is $29.7, and each movie is $6.80

The original price of a computer games is 45$. The price is marked down by 18$. What percent of the original price is the markdown?
Answer:
40%
Step-by-step explanation:
When we say the price of an object is marked down, it means the price of the object was reduced or decreased from the initial or original price.
In the above question:
The original price of a computer game = $45
The price is marked down or decreased by $18
We are asked to find the percent of the original price that is marked down.
This is calculated as:
(The price that the original price is marked down by ÷ Original price ) × 100
= ($18 ÷ $45) × 100
= 40%
Therefore, the percent of the original price that is marked down is 40%.

Marble Slab Creamery is creating a cone-shaped paper wrapper for its new green Baby Yoda waffle cone. The wrapper should have a radius of 5 cm and a slant height of 10 cm. One location wants to offer the cones a weekend earlier, so they plan to make the cone-shaped wrappers for first 25 waffle cones sold that Saturday. About how many square cm of wrapper paper will they need? (Round up to the nearest cm.)
Answer:
3927 cm² wrapping paper will be required.
Step-by-step explanation:
Lateral surface area of a cone shaped wrapper = πrl
where, r = radius of the waffle cone
and l = slant height of the cone
It has been given in the question, radius 'r' = 5cm
and lateral height 'l' = 10 cm
Lateral surface area of the cone = π(5)(10)
= 50π
= 157.08 cm²
If they plan to make 25 waffles then wrapper paper required
= 25×157.08
= 3927 cm²
Therefore, 3927 cm² wrapping paper will be required.

Suppose triangle ABC is dilated with center (0,0) and scale factor 0.25, and the resulting image is then reflected in the x-axis to make triangle PQR. What are the coordinates of point P?
Coordinate of P, after the sequence of transformation is
(-1.25, -1)
How to find the coordinate of P
To find the coordinate of P we first establish that P is in corresponding position with A
Coordinate of A is (-5, 4)
Dilation by 0.25 will result to (-5 * 0.25, 4 * 0.25) → (-1.25, 1)
Reflection over the x-axis is done as follows
(-1.25, 1) → (-1.25, -1)
what is 100 percent if 27 is 45%
Answer:
YOUR WRONG 27 IS NOT 45%
Step-by-step explanation:
[tex]\frac{27}{100}[/tex]=27%
100%=1 whole
Answer:
It is 60
Step-by-step explanation:
A better way to rephrase the problem is:
"what is 100 percent of something if 27 is 45% of something. ?"
so
100% * X = ?
given: 27 = 45% * X
Solve for X,
27/ 45% = X
X = 27 / 0.45 = 60
so. 100% * X = 100% * 60 = 1 * 60 = 60
