Verizon charges a $40 sign up fee and $60 a month for their new hotspot. T-Mobile charges a $100 sign up fee and then $40 per month for their new hotspot. After how many months of service will the two company's fees be the same?
It will take 3 months for both company's fees be the same
Let
y = total charges
x = number of months
Verizon:
y = 40 + 60x
T-Mobile:
y = 100 + 40x
Number of months it will take both companies to charge the same fee
Equate the total charges of both companies
40 + 60x = 100 + 40x
40 - 100 = 40x - 60x
-60 = - 20x
x = -60 / -20
x = 3 months

What effect will replacing x with (x - 4) have on the graph of the equation y = (x - 3) ^ 2 ?
a. slides the graph 7 units down
b. slides the graph 4 units up
c. slides the graph 1 unit right
d. slides the graph 4 units right
Answer:
d. slides the graph 4 units right
Step-by-step explanation:
When you replace x with x - h, the graph shifts h units horizontally.
Here, the replacement is x - 4.
Compare x - 4 to x - h.
h = 4
The shift is 4 units right.
Answer: d. slides the graph 4 units right

2. The equation y = 7x gives the cost y of x pounds of chicken at the grocery store. Complete the table for the given weights of chicken
Equation representing the relation between the cost and the weight of the chicken has been given as,
y = 7xHere, y = cost of the chicken
x = weight of the chicken
By substituting the values of different weights (x) in the given equation we can find the cost of the chicken (y).
For x = 1,
y = 7×1
y = 7
For x = 2,
y = 7×2
y = 14
For x = 3,
y = 7×3
y = 21
For x = 8,
y = 7×8
y = 56
Therefore, the complete table will be,

And the high of this cylinder is 2 units.
Volume of cylinder is given by the formula :
V= h.pi.r²

9 1/4 inches / 12 inches / foot = .770833 feet to 6 decimal places.
9.770833 feet is the length of the given board.
11.25 inches = 11.25 / 12 = 0.9375 feet
So the amount of board used is 9.770833/0.9375 = 10. 42222 feet used in cutting up the board.
Therefore there is 10.42222187 board cut up. The decimal is the remainder.
0.42222187 * 12 = 5.066 inches or rounded to 5 inches.

A 3cm x 2cm rectangle sits inside a circle with a radius of 4cm
What is the area of the shaded region
round your final answer to the nearest hundredth
The area of the shaded region is 44.24\ cm^{2}44.24 cm2
Step-by-step explanation:
we know that
The area of the shaded region is equal to the area of the circle minus the area of rectangle
step 1
Find the area of circle
The area of the circle is equal to
A=\pi r^{2}A=πr2
we have
r=4\ cmr=4 cm
substitute
A=\pi (4)^{2}A=π(4)2
A=16\pi\ cm^{2}A=16π cm2
step 2
Find the area of rectangle
The area of rectangle is equal to
A=(3)(2)=6\ cm^{2}A=(3)(2)=6 cm2
step 3
Find the difference
16\pi\ cm^{2}-6\ cm^{2}16π cm2−6 cm2
assume
\pi=3.14π=3.14
16(3.14)\ cm^{2}-6\ cm^{2}=44.24\ cm^{2}16(3.14) cm2−6 cm2=44.24 cm2

OAmalOHopeO.
============================================================
Explanation:
For now, we'll just find the perimeter of the full circle. The term "circumference" is the same as the perimeter of the circle.
Use the circumference formula to get
C = 2*pi*r
C = 2*3.14*5
C = 31.4
The distance around the full circle is approximately 31.4 units. It's approximate because pi = 3.14 is approximate.
We don't want the full distance around the circle. Instead, we want just the length of the green arc shown in the drawing. This is exactly 3/4 of the full circle, aka 3/4 = 0.75 = 75% of the full perimeter.
The length of the green arc is about 0.75*C = 0.75*31.4 = 23.55 units long. Imagine using a cloth ruler (used in tailoring clothes) as one way to confirm that this arc length is roughly 23.55 units long. Or you could imagine unwrapping this curved portion to lay it completely straight and flat against a ruler.

Look at the expressions below.
2√8 x √20
Which of these is equivalent to this expression?
A. 2√28
B. 5
C. 8√10
D. 32√10
Answer:
8 sqrt(10)
Step-by-step explanation:
2 sqrt(8) * sqrt(20)
We know sqrt(a) * sqrt(b) = sqrt(ab)
2 sqrt(8) * sqrt(20)
2 sqrt(160)
2 sqrt(16*10)
2 sqrt(16) sqrt(10)
2 *4 sqrt(10)
8 sqrt(10)
Answer:
First, we can write 2√8 as 2 x √8. This will make the next calculations easier.
So the problem becomes 2 x √8 x √20.
We can group together √8 and √20, to get √160.
And we have: 2√160.
However, this can be simplified further, as 16x10 = 160, and so we obtain the final answer of 8√10.

Answer:
0.249
Step-by-step explanation:
tan(theta) = opposite / adjacent (according to the SOH CAH TOA rule), which effectively means y/x in this case.
So -0.242 / -.970 ≈ 0.249
Other explanation:
On a unit circle,
y = sin(θ)
and
x = cos(θ).
And since, tan = sin/cos, tan(θ) = y/x. You y and x are given, so calculating tan is a matter of dividing them.
An equilateral triangle has a perimeter of 15x3 + 33x5 feet. What is the length of each side?
x3 feet
5 + 11x2 feet
5x2 + 11 feet
5x3 + 11x5 feet
Answer:
the answer is 5×3+11×5 feet
Answer:
4th option
Step-by-step explanation:
An equilateral triangle has 3 congruent sides
Divide the perimeter by 3 for length of side
[tex]\frac{15x^3+33x^5}{3}[/tex]
= [tex]\frac{15x^3}{3}[/tex] + [tex]\frac{33x^5}{3}[/tex]
= 5x³ + 11[tex]x^{5}[/tex] ← length of 1 side
You drive 132 miles in 3 hours. At
that speed, how many hours would it take you to drive 110 miles?
Answer and Step-by-step explanation:
To solve, we need to find how many miles are driven in an hour.
Divide 132 by 3.
132/3 = 44
Now, we need to find how many hours it would take to drive 110 miles.
[tex]\frac{44 miles}{1 hour} = \frac{110 miles}{? hours} \\\\[/tex]
Cross multiply.
[tex]44(?) = 110[/tex]
Divide by 44.
[tex]? hours = 2.5 hours[/tex]
So, it would take 2.5 hours to drive 110 miles.
