Calculate the area of the triangle below.
Answer:
D- 52.5
Step-by-step explanation:
12ft + 3ft = 15ft
base= 15ft
height=7ft
area = 0.5 * b * h
area = 0.5 * 15 * 7
Answer:
52.5 ft^2
Step-by-step explanation:
7ft * 12ft = 84
84 / 2 = 42
7ft * 3ft = 21
21 = 2 = 10.5
42 + 10.5 = 52.5
To solve for a right sided triangle simply multiply the sides as if you were solving a square and then divide it by two. If you split these into two right sided triangles you can just solve each one and then add them

Elise is making 42 chocolate ice cream sundaes. The number of quarts of ice cream she needs is directly proportional to the number of people served. Suppose it takes 3 quarts of ice cream to serve 18 people. Which statements are correct for this situation?
A) Elise needs 7 quarts of ice cream
B) Elise needs 6 quarts of ice cream.
C) The constant of proportionality is 1 /6.
D) The constant of proportionality is 6/ 1.
E) The constant of proportionality is 1/ 8.
Answer:
A (Elise needs 7 quarts of ice cream)
Step-by-step explanation:
Okay so we know that Elise is serving 42 people, since she's making 42 chocolate ice cream sundaes.
Since it takes 3 quarts to serve 18 people, we know that the amount of people divided by 6 will equal the quarts.
So 42 people divided by 6 equals 7 quarts.

Answer:
148cm²
Step-by-step explanation:
seriously why, just why? okay, hold on, we're gonna be here a while
Let's start with the triangles, they're all equal, and we already have their measurements and the formula for the area of a triangle is base x height ÷ 2, so all we have to do is plug:
5 x 8 = 40
40 ÷ 2 = 20
Now we have to multiply by 3 because there's 3 of these abominations:
20 x 3 = 60
So we put that on a back burner while we do the semicircle
So the formula for the area of a circle is pi x radius², so we have to find the radius. We know that each of the triangle bottoms is 5cm, so we just multiply by 3:
5 x 3 = 15
So the diameter of the semicircle is 15cm, now we divide that by two to find the radius:
15 ÷ 2 = 7.5
Now we just plug that into our formula (we're using 3.14 for pi)
7.5² = 56.25
3.14 x 56.25 = 176.625
Usually, we'd stop there, but it's only half of a circle, so:
176.625 ÷ 2 = 88.3125
So now we add both of our areas:
60 + 88.3125 =
148.3125
Normally, that would be the answer, but since we're supposed to be estimating, we round it to the nearest whole number:
148.3125 -> 148
So the area of the figure is 148cm²
if this is wrong, let me know so I can fix it
hope this helps:)

Answer:
10
Step-by-step explanation:
A net has a rectangle at the center and 4 triangles on the sides. The rectangle has a length (c) of 6 meters and height (b) of 2 meters. The triangle labeled a has a height of 6 meters.
Label the net by defining each variable.
a =
m
b =
m
c =
m
Answer:
Area of the rectangular pyramid is 82.8m²
Step-by-step explanation:
Number of rectangle = 1
Number of triangles = 4
Dimension of Rectangle = Length = 6 metres; Height = 2 metres
Dimension of 2 triangles: Base = 6 metres and Height = 8.8 metres
Dimension of other 2 triangles: Base = 2 metres and Height = 9 metres

An alcohol solution was made by mixing 6 fl. oz. of a 20% alcohol solution and 4 fl. oz. of a 5% alcohol solution. What is the concentration of the mixture?
NO LINKS PLZ!!!!
A) 20%
B) 5%
C) 17%
D) 14%
The concentration of the mixture made by mixing 6 fl. oz. of a 20% alcohol solution and 4 fl. oz. of a 5% alcohol solutions is 14%
What is an equation?An equation is an expression used to show the relationship between two or more numbers and variables.
Let x represent the concentration of the mixture, hence:
(6 * 20%) + (4 * 5%) = x * (4 + 6)
1.2 + 0.2 = 10x
x = 0.14 = 14%
The concentration of the mixture made by mixing 6 fl. oz. of a 20% alcohol solution and 4 fl. oz. of a 5% alcohol solutions is 14%

Step-by-step explanation:
The scale factor on the map is 557.
What is scale factor?When a shape is magnified and each side is multiplied by the same number, this is known as a scale factor. The scaling factor is this figure. Scale factors are used on maps to accurately depict distances between locations.
We have,
1 unit = 557 miles.
now, we have to find the scale factor,
i.e., the amount that must be multiplied by the map's unit of measurement to obtain the original distance between the two locations.
So, it means that the x unit = 557 x miles.
i.e. the scale factor = 557
Hence, The scale factor on the map is 557.

Step-by-step explanation: if there are 500 pieces of paper and the entire stack is 1.875 inches tall, you devide the total height by 500. I know Deigo is wrong because you can easily reverse check his work by multiplying 0.015 by the total number of papers 500 you will get 7.5 which is not the height of the stack
1.875/500=0.00375

=> c = 24/25
Answer:
c=0
Step-by-step explanation:
Remove the parentheses
10c - 15 = 9c - 15
10c = 9c
Move the variable to the left
10c-9c=0

what is the value of x in this equation?
(2.4x10^3)x(3x10^x)=7.2x10^9
Answer:
x=6
Step-by-step explanation:
1. (2.4x10^3)x(3x10^x)=7.2x10^9. Divide both sides of the equation by
2.4 x 10^3)x3
which is 10^x = 10^6
2. 10^x = 10^6. since the bases are the same, set the exponents equal
x = 6
so the answer is x = 6
