Answer:
130 offices are in the building
Step-by-step explanation:
first 39/x = 30/100
secondly, you cross multiply 39 x 100 and 30 x x
100 x 39= 3900
3900/30 = 130
Answer:
ANS. = 130
30% or 30/100=39offices
use cross multiplication
100/30 x 39/1 (note 30/100 is inversed to 100/30) math. law
10/3 x 39/1 (using divisor 10)
10/1 x 13/1 (using divisor 3)
10 x 13 = 130
Ans = 130 offices
Ans.Checked
30% of 130 offices
30/100 x 130/1
3/10 x 130/1 (10 as divisor)
3/1 x 13/1 (10 as divisor)
3 x 13 = 39

As a fundraiser for a band trip, the Edison Middle School Band plans to sell hats that feature the
school logo. The company producing the hats will charge the band $240 for the design and set-up
costs, plus $8 per hat. The band members have decided to sell the hats for $12 each.
a. Write an equation that represents the production cost in dollars to make the hats. Describe
what your variables represent.
b. Write an equation that represents the amount of money the band will make from selling the
hats. Describe at your variables represent
Answer:
a. c=240+8x
b. e=12x
Step-by-step explanation:
a. The equation would indicate that the production cost in dollars is equal to the design and set-up cost plus the cost per hat for the number of hats produced:
c=240+8x, where c is the production cost in dollars and x is the number of hats produced.
b. The equation would indicate that the amount of money the band will make from selling the hats is equal to the price per hat for the number of hats sold:
e=12x, where e is the amount of money the band will make from selling the hats and x is the number of hats sold.

The provided arithmetic sequence adds up to 60.
What is an arithmetic sequence?The difference between every two successive terms in an arithmetic series is always the same. The number "a" is the first term, and "d" is the common difference between the sequence. The nth term of an arithmetic sequence is given by. aₙ = a + (n – 1)d
Given an arithmetic sequence 12, 14,16,18
The general formula for the Sum of arithmetic sequence:
Sn = n/2 [2a+(n−1)d]
where: n = the number of terms to be added.
a = the first term in the sequence.
d = the constant value between terms.
In our case,
a = 12
n = 4
and d = 14 - 12 = 2
thus
Sum = 4/2(2*12 + (4- 1 )2)
Sum = 2( 24 + 6)
Sum = 60
therefore, the Sum of the given Arithmetic sequence is 60.

A local bank charges $9 per month plus 24 per check. The credit union charges $7 per month plus 4e per chock. How many checks should be written each month to make the credit union a bottor deal?
The credit union is a better deal when writing or fower checks per month
This question was not properly written
Correct Question
A local bank charges $9 per month plus 2c per check. The credit union charges $7 per month plus 4cper check. How many checks should be written each month to make the credit union a better deal?
The credit union is a better deal when writing fewer checks per month
Answer:
Writing between 0 to 99 checks makes the credit union a better deal.
Step-by-step explanation:
Let the number of checks be represented by x
Note, 1 cent = $0.01
A local bank charges $9 per month plus 2c per check.
2c = $0.02
$9 + 0.02× x
= 9 + 0.02x
The credit union charges $7 per month plus 4c per check.
4c = $0.04
= $7 + 0.04 × x
= 7 + 0.04x
The credit union is a better deal when writing fewer checks per month
Hence:
Credit union < Local bank
7 + 0.04x < 9 + 0.02x
Collect like terms
0.04x - 0.02x < 9 - 7
0.02x < 2
x < 2/0.02
x < 100 checks
Hence, writing less than 100 checks (i.e writing between 0 to 99 checks) makes the credit union a better deal.

Answer:
A) There is a rational relationship, B) Given ratio is not an integer.
Step-by-step explanation:
A) Is the relationship in Part A rational or irrational? Justifty your answer.
From Mathematics we remember that a rational number can formed by dividing a natural number by another natural number. Since Kara and Nathan had two natural numbers {32, 40} as their times of participation in the maze race, ratio between those times can be considered a rational number.
Hence, there is a rational relationship.
B) Can the times for each be written as integers?
The times represents the ratio of the upper number (40) to the lower number (32), the "times" can be written as integer if and only if denominator is equal to 1 after simplifying the ratio. That is:
[tex]x = \frac{40}{32}[/tex]
[tex]x = \frac{20}{16}[/tex]
[tex]x = \frac{10}{8}[/tex]
[tex]x = \frac{5}{4}[/tex]
In consequence, this ratio does not represent an integer. ([tex]1.25=\frac{5}{4}[/tex])

triangle DEF is a right triangle and the of angle D is 28° what are the measures of the other two angles if the measures of angle E is greater than the measure of angle F
Answer:
A possiable answer to solve this could be E is 86 and F is 66
Step-by-step explanation:
All triangles have a 180 degree to them. I just subtracted 28 from 180. Diveded that by 2 then gave one ten degrees more and the other has ten degrees less
The measure of the angle E will be 90° and the measure of the angle F will be 62°.
What is the triangle?A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.
The triangle DEF is a right triangle and the of angle D is 28°.
In a right-angle triangle, one angle will be 90°.
If the measure of angle E is greater than the measure of angle F. Then the angle E will be 90°. Then the measure of the angle F will be given as,
We know that angle D and angle F are complementary. Then the equation is given as,
∠F + ∠D = 90°
∠F + 28° = 90°
∠F = 62°
The measure of the angle E will be 90° and the measure of the angle F will be 62°.

D. 95%
E. 99.7%
Answer:68%
Step-by-step explanation:
just took this test
The percentage of values is within the interval 111 to 139 will be "68%".
ProbabilityAccording to the question,
Mean = 125
Standard deviation = 14
Let,
The random variable be "X".
Now, the probability:
→ P(111 < X < 139) = P (111 - 125 < X - 125 < 139 - 125)
= P(-14 < X - 125 < 14)
= P(-[tex]\frac{14}{14}[/tex] < [tex]\frac{(X-125)}{14}[/tex] < [tex]\frac{14}{14}[/tex])
= P(-1 < Z < 1)
When, Distribution function "[tex]\phi[/tex]" now,
= [tex]\phi[/tex](1) - [tex]\phi[/tex](-1)
= [tex]\phi[/tex](1) - 1 + [tex]\phi[/tex](1)
= 2 × [tex]\phi[/tex](1) - 1
= 2 × 0.8413 -1

Step-by-step explanation:
mark me brainliestt please
The Amount will be $607.75 and Interest is $ 107.75 after 4 years.
What is Compound Interest?In order to compute compound interest, multiply the principle of the original loan by the annual interest rate multiplied by the number of compound periods minus one.
The interest you earn on interest is known as compound interest.
Given:
Garrison deposited $500.
Interest = 5%
Time= 4 years.
First, convert R as a percent to r as a decimal
r = R/100
r = 5/100
r = 0.05 rate per year,
Then solve the equation for A
A = P[tex](1 + r/n)^{nt[/tex]
A = 500.00[tex](1 + 0.05/1)^{(1)(4)[/tex]
