how do you do percent proportions? I'm learning those right now, and I have no idea what to do. my teacher isn't the best at explaining things. an example of what I don't get is "4% of what number is 10?" also things such as "16 is what percent of 64?"

Answers

Answer 1
Answer:
Remember these tips:

=>  To turn apercent into a decimal, move the decimal point 2 places to the left.
4%means 0.04 ,  and  50% means 0.5 .

=>  To turn a decimal into percent, movethe point 2 places to the right.
0.062 means 6.2% .

=>  Inmath, whenever you see the word "of", it almost always means "times".
So your 2nd example means

                                    16 = (mystery number) x (64).

Divide eachside by 64 :    16/64 = mystery number = 1/4 = 0.25 .

Move the point 2places to the right.    0.25 = 25% .

Bradley dropped a ball from a roof 16feet high. Each time the ball hits the ground it bounces 3/5 the previous height. Find the height ball will bounce after hitting the ground the fourth time

Answers

Answer:

The ball will bounce to 2.07 feet after 4th drop.

Step-by-step explanation:

Bradley dropped a ball from a roof 16 feet high. So, its the initial height.

Each time the ball hits the ground it bounces 3/5 the previous height.

Means after 1st drop, the ball will again rise to (3)/(5)*16= 9.6 feet.

Similarly after 2nd drop, it will bounce to  (3)/(5)*9.6=5.76

After 3rd drop, it will bounce to (3)/(5)*5.76=3.456 feet

After 4th drop, it will bounce to (3)/(5)*3.456=2.0736 feet

Hence, the ball will bounce to 2.07 feet after 4th drop.

Answer: 2.0736 ft

Step-by-step explanation:

Bounce 1: 16*3/5=9.6

Bounce 2: 9.6*3/5=5.76

Bounce 3: 5.76*3/5=3.456

Bounce 4: 3.456*3/5=2.0736

Suppose Monica Walks 1 kilometer every 15 minutes. How many meters further can she walk in 1 hour at this new rate? EXPLAIN how you found your answer

Answers

Well every 15 minutes he walks 1 step. So divide an hour which is 60minutes by 15 minutes. Then the answer to that you multiply by 1. So the equation would be (60/15)x1= and you will find the answer.

Find the surface area of a triangular prism that has the following dimensions. Use the formula SA = 2 B + Ph . B = 84 mm 2 P = 56 mm h = 5 mm

Answers

the answer is 448 
2 x 84=168
56 x 5 = 280 
168 + 280 is 448

Explain how to find the value of a line's y-intercept using its point-slope equation.

Answers

To find the value of a line's y-intercept using its point-slope equation, you can rearrange the equation to the form y = mx + b, where m represents the slope and b represents the y-intercept. The y-intercept is the value of y when x is equal to 0.

! To find the y-intercept of a line using its point-slope equation, you can substitute the coordinates of any point on the line into the equation and solve for the y-intercept. The point-slope equation is in the form y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope. Once you substitute the values and solve for y, the resulting value will be the y-intercept.
