2. answer:

explanation:540 is 12% of 4500. I don't quite understand what that number is but I'm assuming it's the percentage number and that number is 12 and that's 12% out of 100. if it means what percentage 540 is out of 100 then its 540%

3. answer:30
explanation: 4 out of 20 is 20% converted to decimal is 0.2 then multiply it by 15 0 and that adds to 30.

i hope this helped and i hope its correct

At Dunkin Donuts the corn muffins they make represent 40% of the total muffins they bake everyday. On Monday they make 20 corn m

stellarik [79]

Answer:

50 muffins

Step-by-step explanation:

20 : 40%

y : 100%

$\frac{20}{y} :\frac{40}{100}$

y · 40 = 20 · 100

40y = 2000

40y ÷ 40 = 2000 ÷ 40

y = 50

The volume of a certain right circular cone is 30 cubic inches. What is the volume, in cubic inches, of a second right circular

mrs_skeptik [129]

Answer:

V = 15 in.³

Step-by-step explanation:

The original cylinder has radius r and height h.

V = πr²h

Its volume is 30 in.³, so

πr²h = 30 in.³

The new cylinder has radius (1/2)r and height 2h.

Its volume is

V = π(r/2)²(2h)

V = πr² × 2h/4

V = πr²h/2

πr²h is the volume of the original cylinder, and it is 30 in.³.

V = 30 in.³/2

V = 15 in.³

Solve for x 2(x-7)=0.2(x+2)+5.11

Kryger [21]

Answer:

Step-by-step explanation:

You start off by rewriting the equation:

$2(x-7)=0.2(x+2)+5.11\\$

Then you have to factor:

$2x-14=0.2x+0.4+5.11$

Then you subtract the 0.2x:

$1.8x-14=0.4+5.11$

Add the positives on the right:

$1.8x-14=5.51$

Add 14:

$1.8x=19.51$

Divide:

$x=10.84$

You get x is approximately equal to 10.84

Make b the subject of the formula<br><br>A=1/2bh

r-ruslan [8.4K]

Answer:

$\blue{b = \dfrac{2A}{h}}$

Step-by-step explanation:

$A = \dfrac{1}{2}bh$

Step 1. Switch sides.

$\dfrac{1}{2}bh = A$

Step 2. Since the fraction 1/2 multiplies b, multiply both sides by the reciprocal of 1/2 which is 2.

$2 \times \dfrac{1}{2}bh = 2 \times A$

$bh = 2A$

Step 3. Since h is multiplying b, and you want b alone, divide both sides by h.

$\dfrac{bh}{h} = \dfrac{2A}{h}$

Answer:

$b = \dfrac{2A}{h}$
