Answers

Answer:

88 degrees

Step-by-step explanation:

First, notice that when you rotate a point 272 degrees clockwise, there will be 88 more degrees before it returns to its original point (since a 360 turn is equivalent to not moving, and 360-272=88).

Because of that, we can deduce that rotating a point 88 degrees counterclockwise will be equivalent to rotating it 272 degrees clockwise.

We can know that that's the smallest possible positive answer, because any angle smaller than 360 will be the smallest possible way to express it.

2) Ruth borrows $440 at 0.6% simple interest per month. When
Ruth pays the loan back 4 years later, how much interest does
Ruth pay?

Answers

Answer:

$10.56

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 0.6%/100 = 0.006 per year,

then, solving our equation

I = 440 × 0.006 × 4 = 10.56

I = $ 10.56

The simple interest accumulated

on a principal of $ 440.00

at a rate of 0.6% per year

for 4 years is $ 10.56.

Answer:

450.56

Step-by-step

440 x 0.006 x 4 + 440 =450.56

Rewrite the equation 2y - 4x = 10 in function notation where f(x)= y.
f(x)=

Answers

Answer:

Answer:

f(x) = 5 + 2x

y+4x^2-1 is the same as y=-4x^2+1, then replace y with f(x); f(x)=-4x^2+1. After you do that, replace x with 2; f(2)=-4(2)^2+1. 2^2=4, 4 times -4=-16, -16+1=-15. So f(2)=-15.

Answer:

f(x) = 5 + 2x

Step-by-step explanation:

2y - 4x = 10

     +4x    +4x

2y = 10 + 4x

Now we have a new equation but we have to isolate the variable y.

[tex]\frac{2y}{2}[/tex]  = [tex]\frac{10 + 4x}{2}[/tex]  Then divide to solve for y.

y = 5 + 2x

Since f(x) is the same thing/equal to y we can just replace that.

f(x) = 5 + 2x

Hope that helps and have a great day!

One math student, John, can solve 6 math problems in 20 minutes while another student, Juaquine, can solve the same 6 math problems at a rate of 1 problem per 4 minutes. Who works faster?
1.John
2.Juaquine

Answers

Answer:

John

Step-by-step explanation:

6/20=0.3

1/4=0.25

Juaquine is solving problems at a faster rate as compared to John.

What is the rate?

A rate is a type of ratio that compares two values with distinct units. A rate is expressed as a fraction.

As per the question, we can compare their rates of problem-solving by calculating the number of problems they can solve per minute.

For John, this is 6 problems / 20 minutes = 0.3 problems per minute.

For Juaquine, this is 6 problems / (4 minutes/problem) = 1.5 problems per minute.

Since Juaquine can solve 1.5 problems per minute compared to John's 0.3 problems per minute, Juaquine is solving problems at a faster rate.

Hence, Juaquine works faster as compared to John.
