Answer:
C) 15% off with a $15 rebate
Step-by-step explanation:
So a rebate is like a refund which means:
A) 120(.8) = 96 You use .8 because you’re paying 80%
B) 120-30= 90
C) 120(.85) = 102 you use .85 because you’re paying 85%, now
102-15= 87 Subtract 15 since you get a $15 rebate
D) 120(.9)=108 You use .9 since you are paying 90%
108-20= 88 Subtract 20 since you get a $20 rebate
since C ended up with the lowest price, the answer is C
A regular octagon with side length a cm can be made by cutting off
the four corners of a square board. How long should the sides of the
board be?
Answer:
one side = [tex]\frac{a\sqrt{2}}{2}[/tex]
Step-by-step explanation:
if you draw an octagon on a piece of paper, you can draw a square around it, you should be able to see a diagram of this attached, ignore the 6.
Let's say TP = a
since it's a regular octagon, TP = HT
and using the Pythagoras Theorem, we know a² + b² = c² and thus:
√(AT² + HA²) = HT
and since AT = HA which we will call x, the equation becomes:
√(2x²) = HT = a
rearrange the equation to solve for x and you get:
2x² = a²
x² = [tex]\frac{a^{2} }{2}[/tex]
x = [tex]\frac{a}{\sqrt{2}}[/tex]
which, if you rationalise the denominator, you get:
x = [tex]\frac{a\sqrt{2}}{2}[/tex]

10x+10=180
10x =170 = x = 17
Step-by-step explanation:
Answer:
answer: x = 17 Hope this helps!
2 x 17 + 5 = 39 8 x 17 + 5 = 141
Straight angles are 180 degrees
39 + 141 = 180
So x = 17

(x+2)·2x + (x-1)^2= 2 ?
Answer:
x = 1/3, x = -1.
Step-by-step explanation:
2x(x + 2) + (x - 1)² = 2
Distribute the 2x into x + 2.
2x² + 4x + (x - 1)² = 2
Square (x - 1).
2x² + 4x + x² - x - x + 1 = 2
Combine terms.
2x² + x² + 4x - 2x + 1 = 2
Combine terms again.
3x² + 2x + 1 = 2
Subtract 2 from both sides.
3x² + 2x - 1 = 0
Factor.
(3x - 1)(x + 1) = 0.
Finding the x-values here is the same thing as finding the 0s, so set both of the expressions to 0.
3x - 1 = 0
Add 1 to both sides.
3x = 1
Divide by 3.
x = 1/3.
x + 1 = 0
Subtract 1 from both sides.
x = -1.
Answer:
3x^2+2x+1 primero lo multiplicas y lo que te de lo sumas y asi sacas 3x^2+2x+1

Convert 2 3/5 cups to pints.
Answer:
Decimal Form: 1.3
Exact Form: 13/10
Mixed Number Form: 1 3/10
Step-by-step explanation:
1 pint = 2 cups
Convert the mixed fraction into an improper fraction. 2 3/5 = 13/5 cups
You divide 13/5 by 2, since there are 2 cups in one pint, and you are trying to get pints. 13/5 divided by 2:
Decimal Form: 1.3
Exact Form: 13/10
Mixed Number Form: 1 3/10
A car motercycle leaves at noon from the same location, heading in the same direction. The average speed of the car is 30mph slower than twice the speed of the motorcycle.
Answer:
speed of motorcycle = 40 mph
speed of car = 50 mph
Step-by-step explanation:
Here is the complete question
A car and a motorcycle leave at noon from the same location, heading in the same direction. The average speed of the car is 30 mph slower than twice the speed of the motorcycle. In two hours, the car is 20 miles ahead of the motorcycle. Find the speed of both the car and the motorcycle, in miles per hour.
Speed = distance / time
This question would be solved using simultaneous equation
let m = average speed of the motorcycle
c = average speed of the car
c = 2m - 30 equation 1
20 =(c - m) x 2 equation 2
insert equation 1 into equation 2 and divide through by 2
10 = (2m - 30) - m
solve for m
m = 40 mph
substitute for m in equation 1
2(40) - 20 = 50 mph
I need help please. Find 4 solutions of the equation (sin x)^2 = 1/4 for x between 0 and 360. Please show how you found it if not u will be reported.
Step-by-step explanation:
(sinx)²=1/4sinx=√1/4sinx =1/2sinx=sin30°x=30°hope it helps.
Answer:
x = 30, 150, 210, 330 degrees.
Step-by-step explanation:
(sin x)^2 = 1/4
sin x = +/- √1/4
sin x = +/- /2
In the first quadrant x = angle whose sine is 1/2 = 30 degrees.
There is also a solution in the other 3 quadrants.
In second quadrant where sine = 1/2 , x = 180-30 = 150 degrees,
In 3rd and 4th where sine x = -1/2 the angles are 210 and 330 degrees.

The correlation coefficient between two quantitative variables is approximately 0.02. What does the value of this correlation coefficient indicate about how well the model
fits the data?
O A. The correlation coefficient is not within the correct range.
O B. The model is a good fit.
OC. No conclusion can be drawn regarding how well the model fits the data.
The model is not a good fit.
Answer:
The model is not a good fit
Step-by-step explanation:
The correlation Coefficient is a metric used to evaluate the strength of the relationship between 2 variables, the correlation Coefficient ranges from - 1 to + 1 with values closer to either ±1 depicting the strongwr and better relationship. A value of 0 means no relationship exists and values close to zero means the relationship is weak. Wutb a correlation Coefficient value of 0.02, this value is very close to 0 and hence shows that the relationahip is extremely weak. Hence, the model is not a good fit.

Find the angle measures
Answer:
m<1 = 140º
m<2 = 40º
Step-by-step explanation:
5x + x + 12 = 180
6x + 12 = 180
6x = 180 - 12
6x = 168
x = 28
<1 = 28 x 5 = 140º
<2 = 28 + 12 = 40º
