I have to find x but I am not sure how to?
Answers
Answer:
Supplementary angles add to 180
So, the angle supplementary to the angle of 112 degrees measures 68 degrees.
If these two lines are parallel, the angles are the same.
So, the triangle has angle measures: 2x, 68, and 68.
2x+68+68=180
2x=44
x=22

Suppose payments were made at the end of each month into an ordinary annuity earning interest at the rate of 2.5%/year compounded monthly. If the future value of the annuity after 10 years is $60,000, what was the size of each payment? (Round your answer to the nearest cent.) $
Answers
Answer:
Monthly payment= $440.71
Step-by-step explanation:
Giving the following information:
Mothly interest rate (i)= 0.025/12= 0.00208
Number of periods (n)= 12*10= 120 months
Future Value (FV)= $60,000
To calculate the monthly payment, we need to use the following formula:
Monthly payment= (FV*i) / [(1+i)^(n) - 1]
Monthly payment= (60,000*0.00208) / [(1.00208^120) - 1]
Monthly payment= $440.71

Answers
Answer:
A. 3.500 + 0.15. 3,500
E. 3,500. (1 + 0.15)
Step-by-step explanation:
Gallons of water used in June = 3,500 gallons
In July, they used 15% more water
Water used in July = 3,500 + 15% of 3,500
= 3,500 + 0.15 * 3500
A. 3.500 + 0.15. 3,500
E. 3,500. (1 + 0.15)
= 3,500 * 1 + 3,500 * 3,500
= 3,500 + 0.15 * 3500
Sue has 4lbs 6oz of apples. Her younger brothers ate some and now she has 2lbs and 10oz how many lbs and oz of apples did they eat
Answers
Answer: 1 lbs 12 oz
Step-by-step explanation:
First and foremost, we should note that 16 ounces = 1 pound
Sue has 4lbs 6oz of apples. This in ounces will be:
= (4 × 16) + 6
= 64 + 6
= 70 ounces
Her younger brothers ate some and now she has 2lbs and 10oz. The ounces of apples left will be:
= (2 × 16) + 10
= 32 + 10
= 42 ounces
Therefore, the amount they ate will be:
= 70 ounces - 42 ounces
= 28 ounces
Since 16 ounces = 1 pounds
= 1 pounds 12 ounces
= 1 lbs 12 oz
how much force is needed to accelerate a 70kg car at 10m/s^2?
Answers
Change in velocity (v) results in change in momentum (p), which is equal to impulse. Impulse (J) is also equal to an applied force (F) over a period of time (t).
Combining p=mv and J=F t together:
m (v final - v initial) = F t
(2,500 kg) (70 m/s - 30 m/s) = F (10 s)
Solving for F we get:
10,000 N of force

24(3x - 1) = 28(x + 7)
72x - 24 = 28x + 196
72x - 28x = 196 + 24
44x = 220
x = 220/44
x = 5

Dakota earned $11.25 in interest in Account A and $25.00 in interest in Account B after 15 months. If the simple interest rate is 3% for Account A and 5% for Account B, which account has the greater principal? Explain.
Which account has the greater principal? Select the correct answer below and fill in the answer boxes to complete your choice.
Answers
Answer:
Step-by-step explanation:
I=Prt
11.25=A(0.03)(15/12)
11.25=A(0.0375)
A=11.25/(0.0375)
A=$300
25=B(0.05)(15/12)
25=B(0.0625)
B=25/(0.0625)
B=$400
So account B has the greater principal.

Ericka is selling baked goods. She sells x cookies for $0.70
each and also sells one cake for $14.50. She makes a total
of $36.90. Write and solve an equation to determine how
many cookies she sold.
Answers
Answer:
.70x + 14.50= 36.90 x=32
Step-by-step explanation:
0.7x=36.9-14.5
0.7x=22.4
x=32
Answer:
i believe the correct answer here is 53
Step-by-step explanation:
so if 1 cookie is 70 cents, then you determine how many cookies is $36.90
you use proportion and say(convert to cents)
70: 1
3690: more
and calculating using proportion, you get 52.714285714286 and when you round it off it's 53. to prove your answer you say 0.7 × 52.7 = 36.9
If x increases by 7 in each row of a table of values, and the first differences are all equal to 45.5, then the rate of change is:
a) 6.5
b) 455/7
c) 7/455
d) 318.5
Answers
Answer:
b i think
Step-by-step explanation: dont yell just tell me if i got it wrong if i did srry
The rate of change when x increases and the first difference equal to 45.5 is 6.5. Then the correct option is A.
What is the slope?The slope is the ratio of rising or falling and running. The difference between the ordinate is called rise or fall and the difference between the abscissa is called run.
The slope is given as
[tex]\rm Slope = \dfrac{Rise \ or \ fall}{Run}[/tex]
If x increases by 7 in each row of a table of values and the first differences are all equal to 45.5. Then the rate of change will be given by the slope.
[tex]\rm \\Slope = \dfrac{45.5}{7} = 6.5[/tex]
The rate of change is 6.5.
