Which question can be answered by finding 3 1/2÷1/4
A.You have 3 1/2 meters of ribbon and use 1/4 meter. How much ribbon is remaining?
B.How much is 1/4 of a 3/1/2-meter long piece of ribbon?
C.How many 1/4-meter long pieces of ribbon are needed to have a total of 3 1/2 meters of ribbon?
Answers
Answer: Choice C.
How many 1/4-meter long pieces of ribbon are needed to have a total of 3 1/2 meters of ribbon.
==========================================================
Explanation:
Let's consider a similar problem without the fractions.
Let's say you want to know how many 2 meter lengths of ribbon you can cut from an overall length of 24 meters. That would be 24 ÷ 2 = 12 pieces total.
So we divide the two values (large ÷ small)
The same idea applies to this problem as well. The larger amount (3 & 1/2 meters) is what we cut up, and each slice is 1/4 of a meter. To find the number of pieces, we would compute 3 1/2÷1/4
Note: it might help to convert the mixed number 3 & 1/2 to the improper fraction 7/2

You notice a hot air balloon descending. The elevation h (in feet) of the balloon is modeled by the function h(x)=−6x+330, where x is the time (in seconds) since you first noticed the hot air balloon. ANSWER FASTTTTT!!!
Answers
Answer:
55 secsStep-by-step explanation:
Given the elevation h (in feet) of the balloon modeled by the function h(x)=−6x+330, we can calculate the time it takes the balloon to reach the ground. The hot air balloon hits the ground at h(x) = 0.
Substitute h(x) = 0 into the modeled expression and find x as shown;
h(x)=−6x+330
0 = −6x+330
6x = 330
Divide both sides by 6
6x/6 = 330/6
x = 55 seconds
Hence the hot air balloon hits the ground after 55 seconds

Find the fifth term in the geometric
sequence, given the first term and
the common ratio.
a1 = 2 and r = 3
a5 = [ ?]
Answers
Since a1 = 4
a2 = 4 * (3) = 12 i.e( a1* common ratio)
a3 = 12 * (3) = 36 i.e( a2 * common ratio)
a4 = 36 * (3) = 108 i.e( a3* common ratio)
a5 = 108 * (3) = 324 i.e(a4*common ratio)
and so on
The fifth term is 162 in the geometric sequence.
What is geometric sequence?The geometric sequence defined as a series represents the sum of the terms in a finite or infinite geometric sequence. The successive terms in this series share a common ratio.
The nth term of a geometric progression is expressed as
Tₙ = arⁿ⁻¹
Where a is the first term, r is the common ratio
What is arithmetic sequence?A arithmetic sequence is defined as an arrangement of numbers which is particular order.
The formula to find the general term of an arithmetic sequence is,
aₙ = a₁ + (n-1)d
Given data :
First term of sequence geometric (a₁) = 2
The common ratio of geometric (r) = 3
To determine the fifth term of geometric sequence
Let the fifth term of sequence = a₅
The nth term of a geometric sequence is expressed as :
Tₙ = a₁rⁿ⁻¹
Substitute the values of n = 5, a₁ =2 and r = 3 in the formula,
T₅ = (2)(3)⁵⁻¹
T₅ = (2)(3)⁴
T₅ = (2)(81)
T₅ = 162
Hence, the fifth term is 162 in the geometric sequence

Use the midpoint formula to calculate the midpoint.
Use the formula to find the end point, and double the distance between your endpoint and midpoint to find the other endpoint.
Since the distance between the x coordinate is 8 (from -1 to 7), then the other endpoint is 8 away from -1, or -9.

Mrs. Williams combined 3 ½ cups of peat moss, 5 ¼ cups of compost , and 6 ¾ cups of fertilizer to make plant food for her roses. She evenly distributed the plant food among 4 rose bushes. How many cups of plant food were used for each rose bush?
Answers
Answer:
3 7/8 cups plants food
Step-by-step explanation:
peat moss = 3 ½ cups
compost = 5 ¼ cups
fertilizer = 6 ¾ cups
Total mixture = peat moss + compost + fertilizer
= 3 ½ cups + 5 ¼ cups + 6 ¾ cups
= 7/2 + 21/4 + 27/4
= 14+21+27/4
= 62/4
Total mixture = 62/4 cups
She evenly distributed the plant food among 4 rose bushes
Each rose bush uses = Total mixture / number of rose bushes
= 62/4 ÷ 4
= 62/4 × 1/4
= 62/16
= 3 14/16
= 3 7/8 cups plants food
Each rose bush uses = 3 7/8 cups of plants food

James’s little brother and sister wanted to get a face paint. There were 5 kids in front, each kid takes 15 minutes to get their face painted. How many minutes do they have to wait after 3 kids?
Answers
Answer:
9 minutes
Step-by-step explanation:
As it states in the question it takes 15 minutes to paint 5 kids so you do 15/5=3
So it takes 3 minutes to paint each kid.
In the problem it asks how long does it take to paint three kids.
So now we do 3 minutes*3 kids=9 minutes
So it takes 9 minutes to paint three kids

Answers
Answer:
Since pitch is such a close proxy for frequency, it is almost entirely determined by how quickly the sound wave is making the air vibrate and has almost nothing to do with the intensity, or amplitude, of the wave. That is, "high" pitch means very rapid oscillation, and "low" pitch corresponds to slower oscillation.

For △PQR and △EFD shown, which of the following could be steps to show that the SSS congruence criteria follows from the definition of congruence in terms of rigid motion? Select two correct answers.
A.Translate EFD so that point F maps to point Q.
B. Rotate (Triangle)E'F'D' so that D' E maps to PR.
C. Reflect (Triangle) E"F"D" across PR so that E" F" maps to QR.
D. Translate (triangle) EFD so that point D maps to point P.
E. Rotate (triangle) E'F'D' so that D'F' maps to PQ.
Answers
Answer:
Letter B is the answer.
Step-by-step explanation:
B is the answer because you would want to rotate figure EFD to PQR, where line DE would line up with PR.
A is not correct because a translation would not line up the lines or points. Triangle DEF is facing in a different direction as PQR.
C is not correct because it is only being reflected once and the line upon where it is being reflected wouldn't match up with the triangle PQR. EF would not be able to mapped onto line QR because of the line it is being reflected upon.
D is not correct for the same reason as A, which is because a translation would not line up the lines or points. Triangle DEF is facing in a different direction as PQR.
E gets close because of it being rotated, but it is incorrect since line DF wouldn't match up with line PQ. PQ is only congruent to line EF.
