The place value digital is in the tenths place as a decimal
Or as you can see if the was 837 And what's the place value of eight .It should be hundreds.Good luck with that and I explain it

A square pyramid has a height of 25 ft and each side of the base has a length of 15 ft.
Naya [18.7K]

Answer:

Surface area of square pyramid is computed as follows:

A = a² + a*√(a² + 4h²)

where <em>a</em> is the base length and <em>h</em> is the height.

If a model of the square pyramid is scaled down by a factor of x, then the surface area will be:

A' = (a/x)² + (a/x)*√[(a/x)² + 4(h/x)²]

A' = a²/x² + a/x * √[a²/x² + 4h²/x²]

A' = a²/x² + a/x * √[(a² + 4h²)/x²]

A' = a²/x² + a/x * √(a² + 4h²)/√x²

A' = a²/x² + a/x² * √(a² + 4h²)

A' = 1/x² * [a² + a*√(a² + 4h²)]

A' = 1/x² * A

That is, the surface area will be 1/x² times the original surface area. If h = 25 ft and a = 15 ft:

A = 15² + 15*√(15² + 4(25)²) =  1008.02 ft²

The factor is not mentioned in the question, nevertheless, the area will be  1008.02/factor² ft²

Mark recorded the growth of a plant over 8 weeks. The equation y=0.2x+2 represents the height y, in inches, after x weeks.
klio [65]

Answer:

Step-by-step explanation:

The equation representing the growth of the plant after x weeks is expressed as

y = 0.2x+2

Where

x represents the number of weeks.

y represents the height of the plant after x weeks in inches.

A.

The height of the plant after week 3 was about 2.6 inches. We can check by substituting x = 3 into the equation. It becomes

y = 0.2 × 3 + 2 = 2 + 0.6 = 2.6 inches. It is correct.

B is incorrect.

C.

The height of the plant after week 9 was about 3.8 inches. We can check by substituting x = 9 into the equation. It becomes

y = 0.2 × 9 + 2 = 2 + 1.8 = 3.8 inches. It is correct.

D is incorrect

Solve<br><br> 1/5 (x+3)=−(2x+3)
Rasek [7]

Answer:

Step-by-step explanation:

just simplify the LHS first.

You can either multiply 1/5 by (x+3) and then solve

or

multiply both sides by 5 to get rid of 1/5 on LHS

I will multiply by 5

(x+3)= -10x-15     ( 5*1/5(x+3)= -5(2x+3)

now rearrange the equation

x+3=-10x-15

-10x-15-x-3=0

-11x-17=0

-11x=17

x= -17/11
