a quarter has a diameter of 2.4. if it makes 8 rotations how far did it roll
Answer:
7.536
Step-by-step explanation:
I think it means to find the perimeter and multiply it by 8.
The perimeter of a circle is called the circumference.
C = pi(d)
C = pi(2.4)
C = 7.536
My teacher has us use 3.14 for pi so if your teacher has you use something else just multiply it by 2.4.

An angle measures 14° less than the measure of its complementary angle. What is the measure of each angle?
Answer:
38 and 52
Step-by-step explanation:
x = small angle
Complementary angles add to 90 degrees
x + x+14 = 90
2x = 76
x= 38
90-38 = 52
52-14 = 38
38 +52 = 90

4 h(-10) =
5. g(-1) =
6. h(0) =
7. g(20) =
8. h(-4)=
Answer:
Step-by-step explanation:
1. g(1) = (1)³ - 5(1) = - 4
2. At x = 11 function g(x) is not defined,
3. h(5) = 2(5) - | 5 - 10 | = 5
4 h( - 10) = 2( - 10)² - 2(- 10) + 1 = 221
5. g(- 1) = - (- 1)² - 5(- 1) + 2 = - 1 + 5 + 2 = 6
6. h(0) = 3(0) - (0)³ = 0
7. g(20) = - √[3(20) - 16] = - 2√11
8. h(- 4) = not defined
The value of each function is shown below.
What is Function?A function is an expression, rule, or law in mathematics that describes a relationship between one variable (the independent variable) and another variable (the dependent variable). Functions are common in mathematics and are required for the formulation of physical relationships in the sciences.
From the given function we can find the values as:
g(1) = x³ - 5x
g(1) = 1³ -5 = -4
2. For x= 11 the function g(x) is not defined.
3. h(5) = 2x - |x -10|
h(5) = 4
4. h(-10) = 2x² - 2x + 1
h(-10) = 221
5. g(-1) = -x² -5x + 2
g(-1) = 6
6. h(0) = 3(0) - (0)³
h(0) = 0
7. g(20) = - √[3(20) - 16]
g(20) = - 2√11
8. h(- 4) is not defined for the function h(x).

A gazelle can run at a rate of 65 miles per hour. Is this a faster or slower rate than a cheetah, which takes 30 minutes to swim 32 miles? Show your work.
Answer:
Faster
Step-by-step explanation:
We can find their rates by dividing the number of miles by number of minutes:
First, find the gazelle's. Convert the 1 hour to 60 minutes:
65/60
= 1.083
Then, find the cheetah's:
32/30
= 1.067
Since 1.083 is bigger than 1.067, the gazelle has a faster rate than the cheetah.

What is the measure of angles DEC and GAH?
Answer:
DEC is 30°
because 180° - 50° would be 40°
Find x. Round to the nearest tenth if needed.
Answer:
x = 16
Step-by-step explanation:
Use that the addition of all internal angles of a triangle must add up to 180, and the fact that the two given triangles are similar:
51 + 65 + 4 x = 180
combine and solve for "x"
116 + 4 x = 180
4 x = 180 - 116
4 x = 64
x = 64 / 4
x = 16
Answer:
x = 16
Step-by-step explanation:
A triangle is 180 degrees. Since two of the angles are congruent to each other, the third angle must be congruent as well. This means that the third measure for both triangles is 4x. Knowing all of this, we can solve for x:
65 + 51 + 4x = 180
116 + 4x = 180
4x = 64
x = 16

S= √3+2√3+3√3+...10√3
write S as a√3
Answer:
S = 55√3Step-by-step explanation:
S=
√3+2√3+3√3+...10√3 =√3( 1 + 2 + 3+...+ 10) =√3(1/2)(10)(10 + 1) =√3(55) =55√3S = 55√3
Answer:
s=✓3(1+2+3+...10)
s=✓3[10/2×(10+1)]
here, applying sum of 1st n natural number is n/2×(n+1)
so, s=✓3×5×11
hence, s=55✓3.
Dawn's credit card has an APR of 15%, calculated on the previous monthly
balance, and a minimum payment of 2%, starting the month after the first
purchase. Her credit card record for the last 7 months is shown in the table
below.
The total amount that Dawn has paid in interest over the 7 months is $125.13
What is the basis for computing the interest paid monthly?
The interest in a month is computed on the ending balance as at last month, in other words, in month 7, the interest is based on the ending balance in month 6, bearing in mind that the interest paid in month 7 is based on month 6 ending balance
interest in month 7=APR/12*month 6 balance
APR=annual percentage rate=15%
month 6 balance=$1,637.20
interest in month 7=$1,637.20*15%/12
interest in month 7=$20.47(closest to $20.46)
total ending balances=($1,700+$1687.25+$1674.60+$1662.04+$1649.57+$1637.20)
total ending balances=$10010.66
total interest=$10010.66*15%/12
total interest=$125.13

Seven more than a number, x, is at most 20
Answer:
x+7 ≤ 20
Just take it step by step:
seven more than a number is a number plus 7 (x+7)- keep in mind we dont know what the number is so we use x to represent the number.
it then says it's equal to at most 20.
This means that it cant equal anything above 20 since 20 is the max. Therefore, it must be 20 and below that x+7 equals
x+7≤ 20
≤ -this symbol means less than or equal to
