4) A cell phone company would like to run a promotion for a limited time. The cellphone
company is activating a phone line for $40. People will have to pay $50 each month for
phone service. Which equation can be used to find y, the amount that someone will pay
for x months?
y = 40x + 10
y = 40x + 50
y = 40 + 50x
y = 10x + 40
In a two-digit number, the units digit is six less than three times the tens digit. Four times the units digit minus five times the tens digit equals 11. Find the digits.
Answer:
The tens digit = 5
The units digit = 9
The two digit number is 59
Step-by-step explanation:
Let the tens digit be represented by x
The units digits be represented by y
In a two-digit number, the units digit is six less than three times the tens digit.
y = 3(x) - 6
y = 3x - 6
Four times the units digit minus five times the tens digit equals 11.
4(y) - 5(x) = 11
4y - 5x = 11
We substitute
4(3x - 6) - 5x = 11
12x - 24 - 5x = 11
Collect like terms
12x - 5x = 11 + 24
7x = 35
x = 35/7
x = 5
y = 3x - 6
y = 3(5) - 6
y = 15 - 6
y = 9
Hence,
The tens digit = 5
The units digit = 9
The two digit number is 59
Answer:
5=tens 9=units

The radius of a circle is 8 in. Find its area in terms of \piπ.
Answer:
201.06 in
Step-by-step explanation:
I'm guessing you meant πr² because that's what you use to find the area of a circle.
Anyways, we know what the radius is, it's 8, so now we just need to plug it in.
π8² = 201.06
or you can do
3.14(8²) = 200.96
Using π just makes it more exact.
Answer:
201.1 in (approx.)
Explanation:
ok x so first I will multiply 8^2 by pi, that gives me an infinite decimal.. but after rounding it up to 1d.p, we get 201.1 inches which is your answer

use the multiplier method to increase £258 by 43
Answer:
The new value after an increase
of £258 by 43 will be: 368.94
Step-by-step explanation:
As we have to increase £258 by 43 using the multiplier method.
Let 'n' represent the new value after the increase of £258 by 43 using the multiplier method.
Using the formula
n = 258 + percentage increase
[tex]=258+\left(43\%\:258\right)[/tex]
[tex]=258\:+\:43\%\:\times 258[/tex]
Factoring out 258
[tex]=\left(1\:+\:43\%\right)\:\times \:258[/tex]
as 1 = 100 / 100 = 100%
so
[tex]=\left(100\%\:+\:43\%\right)\:\times \:258[/tex]
[tex]=143\%\:\times \:258[/tex]
[tex]=\frac{143}{100}\times 258[/tex]
[tex]=\:\frac{143\times 258\:\:}{100}[/tex]
[tex]=\:\frac{36,894\:\:}{100}[/tex]
[tex]=368.94[/tex]
Therefore, the new value after an increase
of £258 by 43 will be: 368.94

Does the table show a proportional relationship? If so, what is the value of y when x is 11
Answer:
Yes, the table shows a proportional relationship
The value of y when x is 11 is 1331
Step-by-step explanation:
Let us check the relation between x and y in the table
∵ x = 4 and y = 64
∵ 64 = 4³
∴ y = x³
∵ x = 5 and y = 125
∵ 125 = 5³
∴ y = x³
∵ x = 6 and y = 216
∵ 216 = 6³
∴ y = x³
∵ x = 10 and y = 1000
∵ 1000 = 10³
∴ y = x³
∵ All the values on the table give the same relation
∴ x and y are proportion
∴ The table shows a proportional relationship
∵ y = x³
∵ x = 11
∴ y = (11)³
∴ y = 1331
∴ The value of y when x is 11 is 1331

Two trains leave Raleigh at the same time one traveling north and the other south the first train travels at 50 miles per hour and the second at 60 miles per hour in how many hours will the trains be in 275 miles apart
Answer:
2.5 hoursStep-by-step explanation:
Step one:
given data
for train one
speed= 50miles per hour
for train two
speed= 60miles per hour
the total distance between both trains=275miles
Step two:
the expression for speed= distance/time
so that, distance= speed*time
let the time be t
we are going to combine both distances
train one distance =50t
train two distance =60t
Hence total distance
50t+60t=275
110t=1=275
t=275/110
t=2.5 hours
It will take 2.5 hours
