Answer:
99
Step-by-step explanation:
You can solve it by Squaring/multiply 18 by itself and 15 by itself then subtract them both:
(18 × 18) - (15 × 15)
324 - 225
99
You could also do difference of two squares:
(x² - y²)
= (x + y) (x - y)
= (18 + 15) (18 - 15)
= (33) (3)
= 99
Answer:
99Step-by-step explanation:
Evaluate
= (18)^2-(15)^2
= 324 - 225
= 99

In the figure, x=2y, y=2z, and z=2w. Find the value of w. A. 12° B. 30° C. 36° D. 45°
Answer:
w=12
Step-by-step explanation:
put it like this
x=x
x=2y
x=4z
x=8w Now, x=8w, y=4w because there are 2 y's and 8/2 is 4, same thing goes with z so z=2w and w=w.
8+4+2+1=15 180/15=12
Write the slope-intercept form of the equation of each line.
11x + 8y = -45
Answer:
y= -11x/8 - 45/8
Step-by-step explanation:
Write this equation in slope intercept form:
y= mx + b
11x + 8y = -45
8y= -11-45
y= -11x/8 - 45/8

Solve the equations in Parts A and B using inverse operations. Check your solutions. In your final answer, include all of your work.
Part A: 5 + x^2 = 2x^2 + 13
Part B: 5 + x^3 = 2x^3 + 13
Answer:
x = - 2√2
x = -2
Step-by-step explanation:
A . 5 + x² = 2 x² +13
5 + x² - 2 x² - 13 = 0
- x² -8 = 0
- x² = 8
x² = -8
x = - √8
x = - 2√2
B . 5 + x³ = 2 x³ + 13
5 + x³- 2 x³ - 13 = 0
- x³ -8 = 0
-x³ = 8
x³ = -8
x = - ∛8
x = -2

Step-by-step explanation:
Evaluating expressions involve solving and simplifying the expression
The result of [tex]\mathbf{-12 - 27}[/tex] is -39The result of [tex]\mathbf{8 + 53 * 0.4 - ( 23-3.2)}[/tex] is 9.4The expressions are given as:
[tex]\mathbf{(a)\ -12 - 27}[/tex]
[tex]\mathbf{(b)\ 8 + 53 * 0.4 - ( 23-3.2)}[/tex]
[tex]\mathbf{(a)\ -12 - 27}[/tex]
Subtract 27 from -12
[tex]\mathbf{-12 - 27 = -39}[/tex]
Hence, the result of [tex]\mathbf{-12 - 27}[/tex] is -39
[tex]\mathbf{(b)\ 8 + 53 * 0.4 - ( 23-3.2)}[/tex]
Start by evaluating the expression in brackets
[tex]\mathbf{8 + 53 * 0.4 - ( 23-3.2) = 8 + 53 * 0.4 - 19.8}[/tex]
Evaluate the products
[tex]\mathbf{8 + 53 * 0.4 - ( 23-3.2) = 8 + 21.2 - 19.8}[/tex]
Add and subtract
[tex]\mathbf{8 + 53 * 0.4 - ( 23-3.2) = 9.4}[/tex]
Hence, the result of [tex]\mathbf{8 + 53 * 0.4 - ( 23-3.2)}[/tex] is 9.4

A radio station is giving away a $100 bill to every 30th caller and movie tickets to every 10th caller. If there are 120 callers, how many callers will get both the $100 and the movie tickets?
Answer:
4 callers
Step-by-step explanation:
Because 10 is a factor of 30, we don't have to worry about it. Every 30th caller will get both rewards. 120/30=4 so the answer is 4.

Divide 2 from both
=-3/1 or -3
Slope= -3
Finding y-intercept= y=mx+b
Choose any point on the line to plug in the x and the y then plug in the slope.
I choose (1,3)

Step-by-step explanation:
How to name a ray:
A ray is part of a line. It has an endpoint and contains all points of the line to one side of the endpoint. To name a ray, use two points on the ray. The first one must always be the endpoint. The second point is any other point on the ray. The arrowhead above the two letters always points to the right.

What is 10 1/5 as an improper fraction?
Answer:
51/5
Step-by-step explanation:
Multiply 10 by the denominator to get the numerator and keep the denominator the same.
The value of the mixed fraction 10¹/₅ as an improper fraction is 51/5.
What is a fraction?Any number of equal parts is represented by a fraction, which also represents a portion of a whole. A fraction is a number that is a component of a whole. By breaking a whole into a number of parts, it is evaluated.
To convert 10¹/₅ to an improper fraction, multiply your whole number (10) by your denominator (10 x 5 = 50), then add your numerator (1) 50 + 1 = 51. Now multiply that by your original denominator (5) to get 51/5.

Karrisa is going water skiing. She has a choice on either renting or purchasing the skis. She must also rent a safety jacket. She can purchase skis for $125 a pair. The rental fee for skis and a safety jacket is $30 per hour. The rental fee for only the safety jacket is $5 per hour. How many hours must she ski for the price of renting skis and purchasing the skis to be the same?
Answer:
5 hours
Step-by-step explanation:
The rental option for h hours costs ...
r = 30h
The purchase option for h hours costs ...
p = 125 +5h
These costs are the same when ...
r = p
30h = 125 +5h
25h = 125 . . . . . subtract 5h
h = 5 . . . . . . . . . divide by 25
Karrisa must ski for 5 hours for the prices to be the same.
The water level of a lake fell by 1 1/2 inches during a 1 2/3-week-long dry spell. Find the average rate at which the water level changed every week.
Answer: The average rate at which the water level changed every week = [tex]-\dfrac35[/tex] inches per week.
Step-by-step explanation:
Given: Change in water level in [tex]1 \dfrac23[/tex] week = [tex]-1\dfrac12[/tex] inches = [tex]-\dfrac32[/tex] icnhes
To find : The average rate at which the water level changed every week.
i.e. Change in water level per week.
As [tex]1\dfrac23 = \dfrac52[/tex]
Change in water level in 1 week = [tex]-\dfrac{3}{2}\div\dfrac52 = -\dfrac32\times \dfrac25= -\dfrac35[/tex]
Hence, the average rate at which the water level changed every week = [tex]-\dfrac35[/tex] inches per week.
We want to find the average rate of change at which the water level changed in a given time period.
We will find that the average rate of change is:
[tex]r = - 0.9 in/week[/tex]
We define the average rate of change as the quotient between the total change and the time it takes.
Here we have:
total change = -(1 + 1/2) in
Time = (1 + 2/3) weeks
Then the average rate of change is:
[tex]r = \frac{-(1 + 1/2) in}{(1 + 2/3) weeks} = - 0.9 in/week[/tex]
This means that the water level decreases, in average, 0.9 inches per week.
