Answer:
Difference= $25.28
Step-by-step explanation:
Giving the following information:
She took $48.95 with her to spend. She spent $23.57 at one store.
<u>To calculate the money she has left, we need to use the following formula:</u>
Difference= total amount of money - money spent
Difference= 48.95 - 23.57
Difference= $25.28
Answer:
a K=2
b A =200
c B = ±2
Step-by-step explanation:
A = kB^2
When A =50 B=5
Substitute these values in
50 = k * 5^2
50 = k*25
Divide by 25
50/25 = k25/25
2 =k
A = 2B^2
When B = 10
A = 2*10^2
A = 2 *100
A = 200
When A =8
8 =2B^2
Divide by 2
8/2 = 2/2B^2
4 = B^2
Take the square root
±sqrt(4) = sqrt(B^2)
±2 = B
Answer:
645 m²
Step-by-step explanation:
This figure has four similar sloping sides, each of which is a triangle with base 15 m and height 14 m.
The formula for the area of a triangle of base b and height h is A = (1/2)(base)(height).
In this case, the area of each of the four triangles is
A = (1/2)(15 m)(14 m) = 105 m².
Since there are four such triangles, the total area of the triangular sides is 4(105 m²) = 420 m².
The area of the base is A = (15 m)² = 225 m²
Combining side area with base area, we get a total surface area of
A = 225 m² + 420 m² = 645 m²
Please note: I am not familiar with the "net" you mention. If you want a problem solved in a particular way, and can share the necessary tool or tools, please do so.
The equation is y=mx+c, in which m is the slope(1/2), c is the y intercept (5), and x is the x intercept (0)
thus, the equation is:
y=(1/2)(0)+5
y=5
hope it helps!
