Step-by-step explanation:
Petra jogs 2 miles in 24 minutes. At this rate, how long would it take her to jog 12 miles?
Answer:
144 minutes or 2 hours and 24 minutes
Step-by-step explanation:
12 miles divided by 2 miles = 6
24 * 6 - 144
So the final answer is 144.
Answer: 144 minutes
Step-by-step explanation:
If she can run 2 miles in 24 minutes and she needs to run 12 miles you need to multiple 24 and 6 ( You get a six because 24 minutes is for TWO miles. So you need to split the 12 in half.)

Byron and Cari are best friends. Byron wants to give a collage photo frame to Cari on her birthday. He measures the photo frame at 12 inches by 18 inches. He wants to cover the photo frame with a golden cloth at a cost of $7 per square inch. How much will it cost for Byron to cover his photo frame?
Answer:
The answer is $1512.
Step-by-step explanation:
First, multiply 12 by 18, you get 216. Then multiply that by 7, you get 1512. Bryon will need $1512 to cover his photo frame.

What is equation modelling? What is a mathematical equation and expression? Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.A mathematical equation is used to equate two expressions.We have a oatmeal cookie recipe that calls for 1/2 cup of butter to make 5 dozen cookies. Wyatt needs to make 12 dozen cookies for the bake sale.
1/2 cup butter is needed for 5 dozen cookies.
For 1 dozen cookies, (1/2)/5 = (1/10) cups of better are needed.
For 12 dozen cookies, 10/12 cups or 5/6 cups of better are needed.
Therefore, for 12 dozen cookies, 5/6 cups of better are needed.

The area of this rectangle is 8cm2
(3x + 1) cm
(2x + 5) cm
Work out the value of x
Answer:
The value of [tex]x = \frac{1}{6}[/tex]
The length of the rectangle [tex]= \frac{3}{2}[/tex] cm
The width of the rectangle = [tex]\frac{16}{3}[/tex] cm
Step-by-step explanation:
Step(i):-
Given that area of the rectangle = 8 cm²
Length of the rectangle (l) = 3x+1
width of the rectangle (w) = 2x+5
The area of the rectangle = length × width
Given that area of the rectangle = 8 cm²
Step(ii):-
Now
(3x+1) ( 2x+5) = 8
⇒ 3x(2x+5) +1(2x+5) =8
6 x² + 15x + 2x +5 =8
⇒ 6 x² + 17x -3 =0
⇒ 6 x² + 18x -x -3 =0
⇒ 6 x ( x+3) -1(x+3) =0
⇒ 6x -1 =0 and x +3 =0
[tex]6x = 1[/tex] and x =-3
[tex]x = \frac{1}{6}[/tex]
The length of the rectangle
[tex]= 3 (\frac{1}{6} ) +1 \\= \frac{3}{2}[/tex]
The width of the rectangle
[tex]= 2 (\frac{1}{6} ) +5[/tex]
= [tex]\frac{16}{3}[/tex]

Look at the angle. Which description is true?
It's less than 90°
It's equal to 90°
It's greater than 90°. HELP ASAP
Answer:
Less than 90 degrees
Step-by-step explanation:If it were equal to 90 degrees it could make a perfect square as the angle and if its more it would be open wide i guess im a bad explainer sorry
Hence , Option B is correct. It is less than 90 degrees.
What is an Angle?A figure which is formed by two rays or lines that shares a common endpoint is called an angle.
How To Solve:Observe the given figure. A perfect Right Angle is in the shape "L"(or opposite/mirror L also). One can measure or construct it using a protractor.
If the L seems to be bent inwards , then its an acute angle and if the L is bent outwards, then it is an obtuse angle.
From the given figure it can be concluded that the angle formed is an acute angle and hence its is less than 90 degrees.

Step-by-step explanation:
Plug the values in and solve.
G = 5u + 2y
G = 5(2.89) + 2(5.7)
G = 14.45 + 11.4

Tommorrow is my test I really need to get goingI need some help?
Answer:
m = 2, c = -8.
Step-by-step explanation:
The general form of a straight line equation is
y = mx + c where m = the slope and c is the y-intercept.
We are given the line
y = 2x + 4
Comparing this with the general form we see that the slope of this line = 2 and the y-intercept C is 4.
Now the given line y = mx + c is parallel to y = 2x + 4 which means that their slopes are the same so we conclude that m = 2.
Now we need to find the value of c which is the y intercept of y = mx + c.
Consider the points A and B:
A is the point where the line y = 2x + 4 intersects the x axis so y = 0 at this point , So substituting in the equation:
0 = 2x + 4
-4 = 2x
x = -2.
So the point A is (-2, 0)
B is the point where y = 2x + c cuts the x axis so here y = 0:
0 = 2x + c
2x = -c
x = -c/2.
Now we are given that the 2 intercepts are 6 units apart, so:
-c/2 - (-2) = 6
-c/2 + 2 = 6
-c/2 = 4
-c = 8
c = -8.

A plane is going to fly 300 miles at a planned speed of 530 mph. The flight will have an average headwind of w miles per hour the entire time, meaning the plane is flying directly against the wind. The time
Tin hours of the flight is a function of the speed of the headwind w, in mph, and can be modeled by
300
T(W) =
530-W
I need help with the bottom part. What does t(110) mean I’m this situation etc.
Answer:
T(100) represents that the plane flies against the wind at 110mph for 0.714 hours
Step-by-step explanation:
Given
[tex]w = headwind[/tex]
[tex]T = time[/tex]
Model:
[tex]T(w) = \frac{300}{530 - W}[/tex] -- This was not properly presented in your question
Required
What does T(110) means
First, we calculate T(110):
Substitute 110 for w in [tex]T(w) = \frac{300}{530 - W}[/tex]
The expression becomes
[tex]T(110) = \frac{300}{530 - 110}[/tex]
[tex]T(110) = \frac{300}{420}[/tex]
[tex]T(110) = 0.714[/tex] -- approximated
T(100) represents that the plane flies against the wind at 110mph for 0.714 hours
