60 cars to 24 cars what is the decrease percentage​

Answers

Answer:

It decreased 60%

Step-by-step explanation:

TO figure this out we must first find 1% of 60

60/100 = .6

Now we find the difference between 60 and 24

60 - 24 = 36

Now that we know how much it decreased we must now find out what percent 36 is of 60.

.6 x 60 = 36

So 36 out of 60 is 60%

So it decreased 60%

Answers

Answer:

48 degrees

Step-by-step explanation:

1) Solve for x

Complementary angles add up to 90 degrees. Therefore, m<A + m<B is equal to 90:

[tex]A+B=90\\(2x+20)+(3x)=90[/tex]

Open up the parentheses

[tex]2x+20+3x=90\\5x+20=90[/tex]

Subtract 20 from both sides

[tex]5x+20-20=90-20\\5x=70[/tex]

Divide both sides by 5

[tex]\frac{5x}{5} =\frac{70}{5} \\x=14[/tex]

Therefore, x is equal to 14.

2) Determine angle A

[tex]A=2x+20[/tex]

Substitute x with 14

[tex]A=2(14)+20\\A=28+20\\A=48[/tex]

Therefore, the measure of angle A in degrees is 48 degrees.

The area of a triangle is 1/2(base)(height) and since this is a right triangle the two legs can be base and height. So the area is 1/2(2x-4)^2 which becomes 1/2(4x^2-16x+16) which is simplified to 2x^2-8x+8. B is the correct answer.

Step-by-step explanation:

The periods when B = 0.5 and 2 are 4π and π, respectively

How to determine the period?

The period of a sine function is calculated using:

T = 2π/B

When B = 0.5, we have:

T = 2π/0.5

T = 4π

When B = 2, we have:

T = 2π/2

T = π

Hence, the periods when B = 0.5 and 2 are 4π and π, respectively

A school group is raising money for a trip. The group needs $450 for travel and $325 for food. They have 6 weeks to raise money selling $1 candy bars.
What is the least number of candy bars the group needs to sell each week to afford the trip?

Answers

Answer:

Step-In total, the amount of money they will need to raise is:

= 450 + 325

= $775

by-step explanation:

They have 6 weeks to raise this money so the amount they have to raise per week is at least:

= 775/6

= $130

The candy bars cost $1 each. They will therefore have to sell a minimum of 130 candy bars each week to afford the trip.
