Answer:
180 ft²
Step-by-step explanation:
In order to find the total area to paint, you need to find the surface area of the entire figure, which is the sum of the areas of all the sides. Since there are 5 faces to the prism, including the bottom, you will need to add the area of all five faces. The sides of the ramp are triangles with a base of 12 ft and height of 5ft. The area of a triangle is: A = 1/2bh. Since there are two triangles with the same dimensions:
12 x 5 = 60 ft²
Next, the top of the ramp is a rectangle with a length of 13 ft and width of 4 ft:
13 x 4 = 52 ft²
The bottom of the ramp is also a rectangle with length of 12 ft and width of 4 ft:
12 x 4 = 48 ft²
Lastly, the height of the ramp is 5 ft with a width of 4ft, also in the shape of a rectangle:
5 x 4 = 20 ft²
Add them all together:
20 + 48 + 52 + 60 = 180 ft²
Answer:
<h2>
<em><u>A=28</u></em></h2>
Step-by-step explanation:
A=0.5bh
A=0.5*8*7
A= 28
Answer:
Ralphie's dad can eat 8 fruit bars without going over his calorie allotment.
Step-by-step explanation:
Given,
Per day calorie intake limit = less than 2126 calories
Calories are already taken = 1586 calories
Calories in each fruit bar = 66 calories
Let,
x be the number of fruit bars that Ralphie's dad can consume.
Calories in each fruit bar*Number of fruit bars + calories already taken < per day limit
Dividing both sides by 66
Answer:
52
Step-by-step explanation:

(I replaced
with
since we are to find
.)
(By the order of operations, we take care of the exponents before whatever else we have here.)
(By the order of operations, we take care of the multiplication as we see if left to right.)
(By the order of operations, we perform addition/subtraction as we see it left to right.)
(This completes the simplification.)
We could have also put this in our calculator as:
4(4)^2 - 2(4) - 4
This would have returned 52.
