In one particular suburb, 85% of families own a beagle. If 34 families own a
beagle in this neighborhood, then how many families are in this suburb?
Answers
Answer:
There are 40 families in the suburb.
Step-by-step explanation:
Given that 85% of the families own a beagle.
Let x be the total number of families in the suburb.
It is also given that 34 families own a beagle
Which means that 85% of x is 34
This can be written as:
[tex]34 = 85\%\ of\ x\\34 = 0.85x\\\frac{0.85x}{0.85} = \frac{34}{0.85}\\x = 40[/tex]
Therefore, there are 40 families in the suburb.

Mika has three and seven - sixteenths cm wire.She needs only two and five - eights cm wire for her project in TLE .How much wire does she need to cut?
Answers
Answer:
13/16 cm wireStep-by-step explanation:
Length of wire that Mika has H = 3 7/16 cm = 55/16 cm
length of wire that she needs N = 2 5/8 cm = 21/8 cm
Total length of wire she has (H) is the sum of total length that she need (N) and the length that she cuts (C). This can be expressed as;
H = N+C
Length of wire she needs N = H-C
Substitute the given values into the expression;
N = 55/16 - 21/8
Find the LCM
N = (55-42)/16
N = 13/16
Therefore she needs thirteenth-sixteenth cm wire

Mrs. Myane had 3/5 kg of sugar. She used 1/4 of it to make fruit pies. How much sugar did she use to make the fruit pies?
Answers
Answer:
3/20
Step-by-step explanation:
What if Mrs. Myane used a similar approach to the problem, but used simpler numbers? Consider this:
Mrs. Myane had 8 kg of sugar. She used 1/4 of it to make fruit pies. How much sugar did she use to make the fruit pies?
We can see that all we need to do here is divide by four or multiply 1/4. Using the same technique, we can figure out that (in the original problem) Mrs. Myane can create an expression similar to this:
(3/5)*(1/4)
This expression can work too: (3/5) ÷ 4
Following that, we get (3/20).
Good luck and keep studying! Apologies for the late reply. I hope it still helps!

7. Tricia and Melanie are both saving money for their summer vacations. They both
began saving at the same time. Tricia started with $10.25 and adds $5.15 to her
savings every month. Melanie did not have a starting amount but adds $10.25 to
her savings every month. Which equation could be used to determine how many
months, m, it will take before Tricia and Melanie both have saved the same
amount of money?
i
Answers
Answer:
5.15m + 10.25 = 10.25m
It will take about 2 months for them to have the same amount of money.
Step-by-step explanation:
Tricia : 5.15m + 10.25
Melanie : 10.25m
Set them equal to each other and solve for m:
5.15m + 10.25 = 10.25m
10.25 = 5.1m
2.01 = m
Sumi rides at a constant speed of 10 ft/s. Write an equation that expresses the distance d that sumi has traveled as a function of the time s in seconds since she started riding her bike
Answers
Answer:
d = 10s
Step-by-step explanation:
The formula for calculating the speed of Sumi is expressed as;
Speed = distance/time
Given
Speed = 10ft/s
time = s seconds
Required
Distance travelled as a function of time;
from the formula;
Distance = Speed * time
Distance = 10 * s
d = 10s
Hence the equation that expresses the distance d that sumi has traveled as a function of the time s in seconds since she started riding her bike is;
d = 10s

Part A: About ⅔ of the students chose to go to the arcade. Calculate the number of buses needed for the arcade trip if each bus can transport 42 students. Explain your step
Answer:
2 buses would be needed for the Arcade trip
Step-by-step explanation:
Step 1
Total number of students = 126
We find 2/3 of the total number of students
2/3 want to go to the Arcade.
Hence,
2/3 × 126 = 252/3
= 84 students.
84 students want to go to the Arcade
Step 2
We are told in the question that
1 bus can transport 42 students
Hence,
42 students = 1 bus
84 students = x bus
Cross Multiply
42 × x = 84 × 1
x = 84 /42
x = 2 buses.
Hence, 2 buses would be needed for the Arcade trip

Answer:
transaction amount for transaction 3 is: -155.15
transaction amount for transaction 4 is: -223.75
Step-by-step explanation:
We need to fill the blanks in the table.
For Transaction 3 and 4 we need to find the transaction amount.
For Transaction 3
The account balance after transaction 2 was 337.50 and account balance after transaction 3 was 182.35.
The transaction amount is: 337.50-182.35 = 155.15
So, transaction amount for transaction 3 is: -155.15
For Transaction 4
The account balance after transaction 3 was 182.35 and account balance after transaction 4 was -41.40
The transaction amount is: -41.40-182.35 = -223.75
So, transaction amount for transaction 4 is: -223.75
