Answer 1

Answer:

Step-by-step explanation:

SOHCAHTOA

Cosine = Adjacent  / Hypotenuse (Hypotenuse is the side opposite from the right angle)

The Hypotenuse is BT which has a measure of 25

Legs are the two sides that are not the Hypotenuse.

The adjacent leg to Angle B is SB which has a measure of 20.

Plug the measures in to get SinB = 20/25

What is 4 dollars + 5 quarters + 4 pennies = $_.__​

Answers

Answer:

$5.29

Step-by-step explanation:

five quarters is 1.25. since we start with four dollars, that gives us 5.25, plus the 4 cents from the pennies, making 5.29.

Answer:

$5.29

Step-by-step explanation:

We have a solid 4 dollars to begin with so we will write $4.

Next we see that there are 5 quarters, each being 25 cents, we add this to 125 cents. We know that 100 cents is equal to a dollar so we add that to 4 and we have an excess 25 cents so we would write $4.25. We also have 4 pennies, each being 1 cent, we add that to $4.25 to get $4.29.

I hope this helps. Here is a reference

$1= 100 cents

Quarter= 25 cents

Dime= 10 cents

Nickel= 5 cents

Penny= 1 cent

The following cone has a height of 4 inches and a volume of 12π. What is the radius of the cone? Enter your answer as the correct value, rounded to the nearest tenth, if necessary, like this: 42.5
show work​

Answers

Answer:

radius=3

Step-by-step explanation:

volumes of a cone = 1/3πr²h

12π = 1/3× π × r² × 4

37.7 = 12.6r²/3

cross multiply

37.7×3=12.6r²

113.1=12.6r²

make r² subject of the formula

r²=113.1÷12.6

r²=8.976

r=√8.976

r=2.996

r=3.0 (to the nearest tenth)
