Answer:

16

Step-by-step explanation:

ratio is 5:4:1

David: Malachy: Paul

David gets 20 (that is 4 times more than the original ration. so need to multiply everything by 4)

4*4=16

1*4=4

new ration- 20:16:4

So David gets 20

Malachy gets 16

Paul gets 4

Write an absolute value equation to satisfy the given solution set shown on a number line.
aivan3 [116]

Answer: IX - 4I ≤ 4

Step-by-step explanation:

In the numer line we can see that our possible values of x are in the range:

0 ≤ x ≤ 8

And we want to find an absolute value equation such that this set is the set of possible solutions.

An example can be:

IX - 4I ≤ 4

To construct this, we first find the midpoint M of our set, in this case is 4.

Then we write:

Ix - MI  ≤ IMI

Notice that i am using the minor and equal sign, this is because the black dots means that the values x = 0 and x = 8 are included, if the dots were empty dots, it would be an open set and we should use the <  > signs.

Can someone help Find the surface area
ankoles [38]

Answer:

1861.39 cm²

Step-by-step explanation:

Given:

d = 15 cm

radius (r) = ½(15) = 7.5 cm

Height = 32 cm

Surface area of a cylinder = 2πrh + 2πr²

Plug in the values

Surface area = 2*π*7.5*32 + 2*π*7.5²

= 1861.39 cm²

Which equation has the least steep graph?
MAVERICK [17]

Answer:

y=\frac{1}{4}x+6

Step-by-step explanation:

y=\frac{1}{4}x+6 is the least steeped graph

  1. The greater the slope, the steeper the line.
  2. Also you use the absolute values of the slopes when determining the steepness.
  • So here it would be: \frac{3}{4},7,\frac{1}{4},2
  • Now, arrange them from least to greatest: \frac{1}{4},\frac{3}{4},2,7

As you can see, \frac{1}{4} is the smallest number/slope.

Hope this helps!

Factor the perfect square trinomial.<br> x(Squared)+4x+4
Nataliya [291]

Answer:

(x + 2)²

Step-by-step explanation:

Given

x² + 4x + 4 ← is a perfect square of the form

(x + a)² = x² + 2ax + a²

Compare like terms

a² = 4 ⇒ a = \sqrt{4} = 2, thus

x² + 4x + 4 = (x + 2)²
