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

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%

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%

Answer:

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

each piece of paper is 0.00375

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

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

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

Answer:

Step-by-step explanation:

1.)

3x=3

x=1

2+y=0

y=-2

solution: (1,-2)

2.)

6y = -36

y = -6

-4x+12 = -12

-4x=-24

x = 6

solution: (6,-6)

Answer:

Top: x=1, y= -2

Bottom: x= 6, y= -6

Step-by-step explanation:

Top:

Isolate x for y: 2(3+y) + y = 0  

Simplify: 6+3y=0

Isolate y for 6+3y=0: y = -2

For x= 3 + y: x = 1

Bottom:

Isolate x for : -4x - 2y= -12:     x= [tex]\frac{-6 + y}{2}[/tex]

Simplify: 6y+ 12 = -24

Isolate y for 6y+ 12 = -24: y = -6

For x= [tex]-\frac{-6 -6 }{2} = 6[/tex] : x = 6

5(2c - 3) = 3(3c - 5)

=> 10c - 15 = 9c - 15c

=> 10c+15c = 9c + 15c

=> 25c = 24

=> 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

Collect like terms

then solve it and you'll get c=0

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:

"1 unit" is about 7.5 on the scale and the distance between Chicago and New York is about 10.8 on the scale.

Step-by-step explanation:

The scale factor on the map is 557.

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.
