Answer:
Yes, they are proportional
Step-by-step explanation:
First, simplify each fraction
30/80 can be simplified by dividing each number by 10
30/80
= 3/8
24/64 can be simplified by dividing each number by 8
24/64
= 3/8
So, each fraction will simplify to 3/8, meaning that they are proportional.

Write the equation of a circle whose center is at (-11,–8) and whose radius is 4.
Answer:
Step-by-step explanation:
[tex](x_c,y_c)=(-11,-8) \quad r=4\\(x-x_c)^2+(y-y_c)^2=r^2 \quad (x+11)^2+(y+8)^2=4^2[/tex]
2(x+3) = 5x+10 - x
Explain your reasoning
Answer:
x= -2
Step-by-step explanation:
2(x+3)=5x+10-x (we need to distribute first)
2x+6=4x+10 (then add like terms)
-2x=4 (now divide)
x= -2

Step-by-step explanation:
The board of a major credit card company requires that the mean wait time for customers when they call customer service is at most 4.50 minutes. To make sure that the mean wait time is not exceeding the requirement, an assistant manager tracks the wait times of 53 randomly selected calls. The mean wait time was calculated to be 4.94 minutes. Assuming the population standard deviation is 2.10 minutes, is there sufficient evidence to say that the mean wait time for customers is longer than 4.50 minutes with a 98% level of confidence?
1. State the null and alternative hypotheses for the test.
2. Compute the value of the test statistic.
3. Draw a conclusion and interpret the decision.
Answer:
H0 : μ = 4.50
H1 : μ > 4.50
Test statistic = 1.525
we conclude that there is no sufficient evidence to conclude that the mean wait time for customers is longer than 4.50.
Step-by-step explanation:
H0 : μ = 4.50
H1 : μ > 4.50
Test statistic :
(xbar - μ) ÷ s/sqrt(n)
(4.94 - 4.50) ÷ 2.10/ sqrt(53)
0.44 / 2.10/ sqrt(53)
= 1.525
α = 1 - 98% = 0.02
Decision region :
Reject H0 ; if Pvalue < α
Pvalue = p(Z < 1.525) = 0.936
Pvalue = 0.936
Since Pvalue > α ; We fail to reject H0
Hence, we conclude that there is no sufficient evidence to conclude that the mean wait time for customers is longer than 4.50.

Just take 30 and - 10% = 27
Because you are looking for the wrong one so you always have to see how many it was before and how many it was after. Sometimes you can minus the number and then that's the answer you get from minusing

Without using your calculator work out 1 7/12 + 13/20. Give answer in its simplest from
Answer:
31/15
Step-by-step explanation:
First, find the common multiplier of 20 and 12 (the lowest number that both fractions can be increased to). This is 60 (12 x 5 = 60, 20 x 3 = 60) and adjust the numerators accordingly: multiply 17 by five to get 85, and multiply 13 by three to get 39. Add them up to get 124/60, and then simplify - the answer will be 31/15! Hope this helps! Sorry if this was tough to understand, typing off my phone, so feel free to ask any questions :)
Answer:
0.720833

Lastly cancel the numerator and denominator if possible
Oriole Rental Company provided the following information to its auditors. For the year ended March 31, 2017, the company had revenues of $876,223, general and administrative expenses of $352,479, depreciation expenses of $131,455, leasing expenses of $108,195, and interest expenses equal to $78,122. If the company's average tax rate is 34 percent, what is the cash flow from operating activity for Oriole Rental? (Round intermediate calculations and final answer to the nearest whole dollar, e.g. 5,275.) Cash flow from operation
Answer:
the cash flow from operation is $267,397
Step-by-step explanation:
Given that
Revenues be $876,223
General and admin expense $352,479
Depreciation expense $131,455
Leasing expense $108,195
Interest expense $78,122
Tax rate is 34%
We need to find out the cash flow from operation
As we know that
Cash flow from operation = (Revenue - general & admin expense - depreciation - leasing - interest) × (1 - tax rate) + depreciation
= ($876,223 - $352,479 - $131,455 - $108,195 - $78,122) × (1 - 0.34) + $131,455
= $205,972 × (1 - 0.34) + $131,455
= $267,397
Hence, the cash flow from operation is $267,397
x = 8 – 2y
x + 3y = 12
9514 1404 393
Answer:
(x, y) = (0, 4)
Step-by-step explanation:
Since we have an expression for x, substitution works nicely.
(8 -2y) +3y = 12 . . . . . . use the first equation to substitute for x in the 2nd
y = 4 . . . . . . . . . . . . subtract 8, collect terms
x = 8 -2(4) = 0 . . . . substitute for y in the first equation
The solution is (x, y) = (0, 4).

2 A line passes through the point (9,-8) and has a slope of 3 ving Write an equation in point-slope form for this line.
Answer:
y=3x-35
Step-by-step explanation:
y=ax+c
a=slope=3; x and y are given, 9 and -8. put into the formula and solve for c.
-8=9*3+c
-35=c
y=3x-35

In the following triangle what is the length of the hypotenuse?
Answer:
Hypotenuse: 6
Step-by-step explanation:
Sin45°=(BC/AC)
Sin45°=(3√2/AC
1/√2=3√2/AC
AC=3×2=6
so hypotenuse = 6
hope it helps
have a great day!!
Answer:
6
Step-by-step explanation:
here's your solution
=> sin 45° = perpendicular/hypotenuse
=> sin 45° = 1/√2
=> perpendicular = 3√2
=> 1/√2 = 3√2/hypotenuse
=> Hypotenuse = 3*√2*√2
=> Hypotenuse = 3*2
=>. Hypotenuse = 6

A man took out a $44,000 construction loan to remodel a house. The loan rate is 8.5% simple interest per year to be repaid in three months. How much is paid back?
9514 1404 393
Answer:
$44,935
Step-by-step explanation:
The amount due will be ...
A = P(1 +rt) . . . . principal P at annual rate r for t years
__
3 months is 3/12 = 1/4 years, so the amount is ...
A = $44,000(1 +0.085×1/4) = $44,935 . . . amount paid back
A person invests $4,250 in an account that earns 5.25% interest compounded annually. let f(t) be the value in dollars of the account after t years. give an equation for f f(t)=______. what will be the value of the account after 5 years? round your answer to the nearest cent. $_______. after 10 years? round your answer to the nearest cent $______
Answer:
see the answers below
Step-by-step explanation:
Given data
P=$4,250
Rate= 5.25%
Time= t years
1. The compound interest expression is
A=4250(1+0.0525)^t
A=4250(1.0525)^t
2. P=$4,250
Rate= 5.25%
Time= 5 years
1. The compound interest expression is
A=4250(1+0.0525)^5
A=4250(1.0525)^5
A=4250*1.2915
A=$5488.875
3. P=$4,250
Rate= 5.25%
Time= 10years
1. The compound interest expression is
A=4250(1+0.0525)^10
A=4250(1.0525)^10
A=4250*1.6680
A=$7089
