Answer:

Step-by-step explanation:

I’m assuming that A has a side of 15 cm and has a volume of 400 cm.

Using our volume formula:

(15/10)^3 = (400/x)

(3/2)^3 = 400/x        <— simplify

27/8 = 400/x

27x = 3200

so the volume of B is 3200/27 or about 118.52cm^3

(if I assumed the wrong side lengths please tell me!)

Let ​g(x)x and ​h(x)<br> . Evaluate .
Maurinko [17]

9514 1404 393

Answer:

  h(g(x)) = (1/5)x² +4/5

Step-by-step explanation:

  (h\circ g)(x)=h(g(x))=h(x^2+2) = \dfrac{(x^2+2)+2}{5}=\dfrac{x^2+4}{5}\\\\\boxed{(h\circ g)(x)=\dfrac{1}{5}x^2+\dfrac{4}{5}}

Write an equation of the line with the same slope as the line given by 5x + 2y = 8 and the same y-intercept as the line given by
kaheart [24]
In y = mx + b form, the slope is in the m position and the y intercept is in the b position.

5x + 2y = 8
2y = -5x + 8
y = -5/2x + 8.....slope (m)  is -5/2

3x - 7y = 10
-7y = -3x + 10
y = 3/7x - 10/7.....y int (b) = -10/7

so ur equation with slope(m) of - 5/2 and y int (b) of -10/7 is :
y = -5/2x - 10/7 <== slope intercept form

Match the expressions to their verbal descriptions. Assume that all variables represent integer values and that none are equal t
Nostrana [21]

The expression for the sum of m and a term depending on m will be m + 3(m - 11)².

<h3>How to depict the expressions?</h3>

The product of m and a multiple of m will be m(-8m).

A product of m and a factor not depending on m will be -3mn²

The difference between n and a factor depending on m will be:

  • m(2mn) - 6m.
  • m - 7mn

Salinas planting a circular flower bed radius of 3 1/2 feet she plans Chase around it with wire fencing that cost 0.89 $ a foot
Brut [27]

Answer:

Total Fencing Cost =$19.57

Step-by-step explanation:

If Rosalina is planning on fencing, we are talking about the Perimeter of the Flower Bed

Perimeter of a Circle = 2\pi r

Radius of the circular flower bed =3.5 ft

Perimeter = 2\pi X 3.5=21.99ft

If Wire fencing Cost $0.89 per foot

Total Fencing Cost = $0.89 X 21.99=$19.57
