A woman has 31 coins in her pocket, all of which are dimes and quarters. If the total value of the coins is $ 5.20, how many dimes and how many quarters does she have?
Answer:
D+Q = 31
10D + 25Q = 595
10D + 10Q = 310
subtract to get
15Q = 285 Q = 285/15 = 19 quarters D = 31-19 = 12 dimes

A small business celebrates serving 5110 customers in their first year of business how many customers did they average each day
The no. of customers they serve per day is equal to 14.
It is given that the total number of customers served in first year of business was 5110.
We have to find that what will be the average of servings per day ?
What do you mean by average ?
The average is the ratio of sum of all numbers to the total no. of numbers.
As per the question ;
Total number of people served in a year = 5110
We know that ;
1 year = 365 days
So ;
To calculate the average of servings per day we need to divide total number of servings by no. of days in 1 year.
i.e.,
Average of customers per day ;
= 5110 ÷ 365
= 14 customers per day
Thus , the no. of customers they serve per day is equal to 14.

Answer:
B
Step-by-step explanation:
Given the 2 equations
a - b + c = 3 → (1)
a + b + c = 7 → (2)
Subtract (1) from (2) term by term to eliminate a and c
a - a + b - (- b) + c - c = 7 - 3 , that is
0 + b + b + 0 = 4
2b = 4 ( divide both sides by 2 )
b = 2 → B

Flying against the wind, an airplane travels 4720 kilometers in 8 hours. Flying with the wind, the same plane travels 4040 kilometers in 4 hours. What is the rate of the plane in still air and what is the rate of the wind?
The rate based on the information will be 590 kilometers per hour and 1010 kilometers per hour
How to calculate the rate?Rate in Mathematics simply demonstrates how many times one number can be able to fit into another number. It should be noted that rate contrast two numbers by dividing them. In this case, A/B will be the formula if one is comparing one variable (A) to another variable (B).
Since the an airplane travels 4720 kilometers in 8 hours. The rate is:
= 4720 / 8
= 590 kilometers per hour
Flying with the wind, the same plane travels 4040 kilometers in 4 hours. The rate will be:
= 4040 / 4
= 1010 kilometers per hour

Answer:
8 x 6 = 48, 48 divided by 2 (x 1/2) = 24 , 24 x 2(there are two triangles) = 48
12 x 10 = 120
8 x 12 = 96
12 x 6 = 72
Now let's add all the given areas:
48 + 120 + 96 + 72 = 336 ft^2 is your answer.

Answer:
C
Step-by-step explanation:
These are not line plots; they are dot plots. Each dot (×) represents one data point. The dot is placed above the corresponding value on the horizontal axis. There are 7 data points, so should be 7 dots. 3 of the data points are 3/4 hour.
Only plots C and D show 7 data points. Only plot C shows three of those data values being 3/4 hour. Plot C is the correct choice.
Find the volume of this sphere.
Use 3 for T.
d=6in
V ~ [?]in3
V = Tr3
Answer:
V = 108 in³
Step-by-step explanation:
Given:
Volume of sphere = ⁴/3πr³
π = 3
d = 6 in.
r = ½(6) = 3 in.
Required:
Volume of sphere
Solution:
V = ⁴/3πr³
Plug in the values
V = ⁴/3 * 3 * 3³
V = ⁴/3 * 3 * 27
V = 4 * 27
V = 108 in³
Round 0.25773438 to the nearest hundredth
Answer:
The answer is 0.26.
I wish you luck on your assignments.
Answer: 0.26
Step-by-step explanation:
1. The hundredths place is two digits from the decimal point
2. Look at the thousandths place and if it is larger or equal to 5 then we round up, otherwise we round down and the hundredths digit remains the same
3. 7 is larger than 5 therefore the hundredths place digit of 5 rounds to a 6
4. Our final answer is 0.26

Five student government officers want to go to the state convention. It will cost them $115 for registration, $365 for transportation and food, and $55 per person for the hotel. There is $485 budgeted for the convention in the student government savings account. They can earn the rest of the money they need by having a car wash. If they charge $6 per car, how many cars must they wash in order to have enough money to pay for the trip?
Answer:
45 cars
Step-by-step explanation:
115+365+(55*5) = 755
755 - 485 =270

The probability that tomorrow's temperature will be average is 55%. The probability that the temperature will be above average is 25%. Work out the probability that the temperature will be BELOW average
Answer:
Probability that the temperature below average = 20%
Step-by-step explanation:
Given:
Probability that tomorrow's temperature average = 55%.
Probability that the temperature above average = 25%
Find:
Probability that the temperature below average
Computation:
Probability that the temperature below average = 100% - Probability that tomorrow's temperature average - Probability that the temperature above average
Probability that the temperature below average = 100% - 55% - 25%
Probability that the temperature below average = 100% - 80%
Probability that the temperature below average = 20%
In this article, Attitudes About Marijuana and Political Views (Psychological Reports, 1973), researchers reported on the use of cannabis by liberals and conservatives during the 1970s.
To test the claim (at 1% significance) that the proportion of voters who smoked cannabis frequently was lower among conservatives, the hypotheses were:
H0:p1−p2=0(p1=p2)
Ha:p1−p2<0(p1
In the hypothesis test about cannabis use by conservatives and liberals, the test statistic was z = -4.27, with a corresponding p-value of about 0.00001.
Which conclusion is most appropriate in the context of this situation?
Answer:
The pvalue of the test is 0.00001 < 0.01, which means that we have sufficient evidence to conclude that the proportion of voters who smoked cannabis frequently was lower among conservatives than liberals.
Step-by-step explanation:
We test:
If the proportion of voters who smoked cannabis frequently was lower among conservatives than liberals.
Corresponding p-value of about 0.00001.
The pvalue of the test is 0.00001 < 0.01, which means that we have sufficient evidence to conclude that the proportion of voters who smoked cannabis frequently was lower among conservatives than liberals.
