Step-by-step explanation: so

l*w*h
7.5ft*4ft*8ft

that would be 240ft^3

Then 2.5^3

would be 15.625^3

Answer:

[tex]3500[/tex]

Step-by-step explanation:

Given the following question:

[tex]3.5\times10^3[/tex]

To convert a scientific notation into standard form we first need to keep in mind that the exponent in indeed a positive. Knowing this we know that the decimal point is going to move to the right.

Since the exponent is three, we know that the decimal point is going to move to the right THREE times.

[tex]3.5\times10^3[/tex]
[tex]3.5\times10^3=3.5.0.0.[/tex]
[tex]3.5.0.0.=3500[/tex]
[tex]=3500[/tex]

Your answer in standard form is "3500."

Answer:

To find the total number of diagonals in a polygon, multiply the number of diagonals per vertex (n - 3) by the number of vertices, n, and divide by 2 (otherwise each diagonal is counted twice).

Step-by-step explanation:

Explanation:

I'm assuming the rope is fully taut and connects the top of the flag pole with the tip of the shadow.

Draw a right triangle that has a horizontal leg of 5 feet and a hypotenuse of 13 feet. I'll call these a = 5 and c = 13.

Use the pythagorean theorem to find b

[tex]a^2 + b^2 = c^2\\\\5^2 + b^2 = 13^2\\\\25 + b^2 = 169\\\\b^2 = 169-25\\\\b^2 = 144\\\\b = \sqrt{144}\\\\b = 12[/tex]

The vertical leg of the right triangle is 12 feet, which is the height of the flag pole. We have a 5-12-13 right triangle.

Answer:

(g ￮ f)(- 5) = 4

Step-by-step explanation:

evaluate f(- 5) then substitute the value obtained into g(x)

f(- 5) = (- 5)² + 6(- 5) + 3 = 25 - 30 + 3 = - 2 , then

g(- 2) = 2(- 2) + 8 = - 4 + 8 = 4

Answer:

358 feet²

Step-by-step explanation:

Answer:

358

Step-by-step explanation:

A= 12 x 5

= 60

x 2 = 120

A= 5 x7

= 35

x 2 = 70

A = 12 x 7

= 84

x2 =168

(I multiply by 2 because 2 sides are equall)

Add:

120 + 70 + 168 = 358

Hope this helps!

Answer:

a = 146

Step-by-step explanation:

The line is 180 degrees so one angle is 34 degrees and the other one would have to add up with it to make 180 degrees. This is where the 146 degrees comes in.

146 + 34 = 180 = degrees

Answer:

x = 54

Step-by-step explanation:

Seven minus a number split into 9 equal parts in one

7 - 1 = (1/9)x

(1/9)x = 6

x = (9)(6)

x = 54

Answer:

the 35th term or a(35) is 69

Step-by-step explanation:

the first thing you must do to solve this equation is to write for the nth term

this is

a(n) = 209 - 4n

i got 209 by adding 4 to 205 to find the 0th term

so to solve the equation for the 35th term oyu just plug it in

a(35) = 209 - 4(35)

a(35) = 209 - 140

a(35) = 69

Answer:

-21, 12

Step-by-step explanation:

We first have to solve each of the list of numbers:

-45 -21 = -66

-21 - 16 = -37

-16+12=-4

33+40=73

-45-16=-61

-45+33 = -12

-45 + 12 = -33

-21 + 12 = -9

Hence, we can conclude that -21 and 12 add up to -9

It’s option A, Choi’s option A

Step-by-step explanation:

The surface area of the actual ramp is 16.8 ft²

An area is the amount of space occupied by the two dimensional shape or object.

The height of the actual ramp = 1.2 feet and the height of the model = 6 cm

Scale factor = 1.2 feet / 6 cm = 0.2 ft/cm

Actual base = 16 cm * 0.2 ft/cm = 3.2 ft

9 cm = 9 cm * 0.2 ft/cm = 1.8 ft, 10 cm = 10 cm * 0.2 ft/cm = 2 ft,

Surface area of actual ramp = 2(0.5 * 3.2 ft * 1.2 ft) + 2(2 ft * 1.8 ft) + (1.8 ft * 3.2 ft) = 16.8 ft²

The surface area of the actual ramp is 16.8 ft²
