Lucy can type 300 words in 5 minutes. How many words can Lucy type in 32 minutes?
Answer:
1920 words
Step-by-step explanation:
Set up a proportion, where x is the number of words Lucy can type in 32 minutes:
[tex]\frac{300}{5}[/tex] = [tex]\frac{x}{32}[/tex]
Cross multiply and solve for x:
5x = 9600
x = 1920
So, in 32 minutes, Lucy can type 1920 words

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

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
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
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?
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?
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!

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?
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.

What should the following equation be multiplied by in order to eliminate the fractions? 2y/3+1/3=y/2+1/6
A. 25
B. 6
C. 5
D. 9
Answer:
B
Step-by-step explanation:
Because if you multiply the fractions by 6, the denominator would be a multiple.
For example, 2/3y x6/1= 12/3y= 4y
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
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
Ella has 425 more bracelets to sell. She wants to
store these in bags that hold 20 bracelets each. She
estimates she needs about 25 bags. Do you agree?
Why or why not?
Answer:
I disagree . I don’t agree because if you have 25 bags with 20 braclets in each then you would just waste So many bags because you can fit 500 bracelets in those bags all together.
Step-by-step explanation:
HOPE THIS HELPS
PLZZ MARK BRAINLIEST
She needs about 20 bags, the exact amount needed 22.
Why:
22 x 20 = 440. Either she'd have five over (then it'd be 21 bags) or a not full bag.
FIND THE VALUE OF X.
1.
(5x - 2)°
(3x + 4)
Answer:
If 5x-2 = 3x+4, then x=3
Step-by-step explanation:
5x-2=3x+4
Add 2 to both sides, and you get 5x=3x+6. Subtract 3x from both sides, and you get 2x=6. Divide both sides by 2, and what's left is x=3. Hope this helps. :)

Step-1 : Multiply the coefficient of the first term by the constant 1 • -2 = -2
Step-2 : Find two factors of -2 whose sum equals the coefficient of the middle term, which is 1 .
-2 + 1= -1
-1+ 2= 1 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -1 and 2
x2 - 1x + 2x - 2
Step-4 : Add up the first 2 terms, pulling out like factors :
x • (x-1)
add up the last 2 terms, pulling out common factors :
2 • (x-1)
Step-5 : Add up the four terms of step 4 :
(x+2) • (x-1)
(x + 2) • (x - 1) = 0

The angles of elevation of a balloon from two points A and C on level ground are 24.5 and 41.3, respectively . Points A and C are 3.5 miles apart and the balloon is between the points. Approximate the height of the balloon above the ground.
Answer:
height of the balloon = 1.0494 miles
Step-by-step explanation:
I drew a triangle and labeled angles A, B and C and sides a, b and c.
a = (c · sin A) / sin C = (3.5 · sin 24.5°) / sin 114.2° = 1.4514 / 0.9121 = 1.59 miles
now we have a 90° triangle
h = (a · sin B) / sin 90° = (1.59 · sin 41.3°) / sin 90° = 1.0494 / 1 = 1.0494 miles
