A circle above has a radius of 6 cm. What is the area of the circle?
Use = 3.14.
Answer:
113.04
Step-by-step explanation:
formula for area is
pi times radius times radius
if the radius is 6,
do 6 times 6=36
36 times 3.14=113.04
x = 6y – 14
-X + 9y = 17
Answer:
(x, y)=(-8,1) this is substantial method
If it is 11:45 a.m., what will the time be 3 hours and 15 minutes later?

Do values of these triangles form right triangles or not using Pythagorean theorem
Answer:
Yes
Yes
No
Step-by-step explanation:
9-12-15 is just a dilation of a 3-4-5, which is right.
6-8-10 is also a dilation of 3-4-5.
However, 2-4-6 is not a triangle. In fact, it's just a line segment, because 2+4=6

Inverse of t = (120r)/(r+120)
9514 1404 393
Answer:
r = 120t/(120 -t)
Step-by-step explanation:
Given t = f(r), solve for r.
[tex]t(r+120)=120r \qquad\text{multiply by $r+120$}\\\\rt+120t=120r \qquad\text{eliminate parentheses}\\\\rt-120r=-120t \qquad\text{subtract $120t+120r$}\\\\r(t-120)=-120t \qquad\text{factor}\\\\r=\dfrac{-120t}{t-120} \qquad\text{divide by $t-120$}\\\\\boxed{r=\dfrac{120t}{120-t}} \qquad\text{negate numerator and denominator}[/tex]

A car rental company charges a $50 deposit and $25 per day.
Answer:
The equation will be y=25x+50
Step-by-step explanation:
This is because 50 is only being charged once and is the constant.
They are charging $25 per day thus that is the slope.
b. Mills works as a construction worker. He makes a salary of 54,200 a year. After
this year his boss decided to give him a 3.5% raise. What is his new salary?
Answer:
$56,097
Step-by-step explanation:
First, we have to figure out how much his raise was, so we can convert 3.5% directly to a decimal:
3.5% = 0.035
Then we find
3.5% of 54,200 = 0.035 x 54,200 = 1,897
1,897 + 54,200 = 56,097
So, Mills new salary is $56,097

Answer:
The answer is
[tex]y = - 5x - 2[/tex]
Step-by-step explanation:
❃Incase you forgot what the linear equation formula is ☟
[tex]y = mx + b[/tex]
❃Incase you also forgot, The is what the slope formula is ☟
[tex]m = \frac{y_2 - y_1 }{x_2 - x_1}[/tex]
➊ First: We are going to be solving for the slope.
[tex]m = \frac{ - 2 - 3}{0 - ( - 1)} = \frac{ - 5}{ \: \: \: 1} = - 5[/tex]
➋Second: We find the y-intercept.
[tex]y = mx + b \\ 3 = - 5( - 1) + b \\ 3 = 5 + b \\ \frac{ - 5 = - 5 \ \ \: \: \: \: \: \: }{ - 2 = b}[/tex]
➌Third: Plug in.
[tex]y = - 5x - 2[/tex]

Step-by-step explanation:
From 1-10 You can see the numbers going from 0-8 on the left side except you repeat the number 4 twice then proceed. Then on the right side you do it backwards but instead you use the 2 times tables and you’re going to want to work your way from bottom to top and then when you reach to 0 which is the number 10 you repeat the 2 times tables again.

How to make a simplified expression for 4(y + 3) - 5
Answer:
4y + 7
Step-by-step explanation:
Simplify. Use the distribution method, and follow PEMDAS.
PEMDAS is the order of operation. It stands for:
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction
Distribute 4 to all terms within the parenthesis. In this case, you are multiplying 4 to all the terms:
4(y + 3) = (4 * y) + (4 * 3) = 4y + 12
Next, combine like terms (terms with the same amount of variables);
4y + 12 - 5
4y + (12 - 5)
4y + 7
4y + 7 is your simplified expression.

The weights in pounds of 6 members of a basketball team are 125, 136, 150, 119,
and 143. Find the mean and the median *
Answer:
Mean:(137.2)
Median:(139.5)
Step-by-step explanation:
Mean = (125+136+150+119+143) divide by six(6)
= 823/6 = approx 137.2
Median = for the median, you will arrange the numbers in other. from smaller to the bigger number.
119,125,136,143,150, 150. so 136 & 143 is the middle number.
so you will add the middle number and divide by 2.
that is 136+143/2 = 139.5.

Students in elementary school attends school five days each week after three weeks of attendance each student has attended school for a total of 6300 minutes for how many hours each day does each student attend the school
Answer:
Step-by-step explanation:
first lets meake the minutes into hours by dividing our minutes into hours
6300 / 60 = 105
so in total they go 105 hours in 15 days (5 days for 3 weeks is 15 days)
to find how many hours in each day lets divide our hours into the 5 days
105 / 15 = 7 hours a day
