Answer: i say B is correct
Answer:
B --> y is 1/3 of x
Step-by-step explanation:
x:y is 3:1
=> x is bigger than y
=> x is 3x bigger than y
=> x = 3 lots of y
=> [tex]x = 3y[/tex]
=> [tex]\frac{x}{3} = y[/tex]
=> [tex]\frac{1}{3} x = y[/tex]
Therefore y is [tex]\frac{1}{3}[/tex] of x
This means that B is correct
Brianna and two friends went to
Popeyes for lunch. Each of them purchased a #5
combo for x dollars. Brianna is the only one they
purchased a drink for $4.50. The total amount spent
was $26.00 before tax. Write and solve an equation
to determine the cost of a #5 combo meal. (Round
to the nearest tenth)
Answer:
The Popeyes Chicken Sandwich is around $3.99. If you order the sandwich as a combo meal with a side, biscuit, and a drink, it will be closer to $8.00. However, prices may vary by location.

The probability of a basketball player hitting a foul shot is 1/3. How many shots would you expect her to make in 90 attempts?
Answer:
60
Step-by-step explanation:
1/3 of all attempts expected to be foul shots
1/3*90= 30 fouls
90-30= 60 success
37 is 60% of what number?
Answer:
61 2/3 = n
Step-by-step explanation:
Is means equals and of means multiply
37 = 60% * n
37 = .60n
divide each side by .60
37 / .60 = .60n/.60
61.6666666 repeating = n
61 2/3 = n

The perimeter of a triangle is 27 feet. One side is 3 feet longer than the shortest side, and the longest side is twice as long as the shortest side. How long is each side?
Answer:
6, 9, 12
Step-by-step explanation:
Let s be the shortest side. Using the information you're given, you can create an equation. 27= s + s+3 + 2s. Now just solve the equation. Subtract 3 from both sides. 24=4s. Divide by 4 on both sides. 6=s. So the shortest side is 6 feet long, so we add 3 to that for the one that is neither the shortest or the longest. That side is 9 feet long. We double s to get 12, which is the longest side.
Answer:
Long side: 12
Middle side: 9
Shortest side: 6

A movie channel sends an email survey to all customers who purchase their service each month. The previous month, 182,000 people purchased
subscriptions. Surveys were sent to 9,000 of these people, chosen at random, and 1,080 people responded to the survey. Identify the population and the
sample.
The population is 182,000 and the sample is 1,080.
The population is 9,000 and the sample is 1,080.
The population is 182,000 and the sample is 9,000.
The population is 9,000 and the sample is 182,000.
Answer:
The population is 9,000 and the sample is 1,080
Step-by-step explanation:
Your population is 9,000 because that is how many people got the survey. The number 182,000 is irrelevant because that information does not matter with regards to the surveys. Your sample is 1080 because that is the number of people that responded.

The probability of choosing a number less than 7 and then a multiple of 4 is?
Answer:
Total probability (first tile less than 7, second tile multiple of 4) = 2/21
Step-by-step explanation:
The question is not complete as the number of tile are not given. Howover, I could find the complete question on internet so I would solve for that. I hope it helps. (SEE THE ATTACHMENT)
QUESTION
You randomly choose a tile. Without replacing the first tile, you choose a second tile. Find the probability of the compound event. Write your answer as a fraction or percent rounded to the nearest tenth. THE PROBABILITY OF CHOOSING A NUMBER LESS THAN 7 AND THEN A MULTIPLE OF 4 IS?
ANSWER
As we can see in the picture that there are a total of 7 tiles, so n = 7
These tiles are numbered as 5, 6, 7, 8, 9, 10, 20
Tiles having a number less than 7 = 5, 6
No. of tiles having a number less than 7 = 2
So probability of choosing a number less than 7 is = 2/7
After picking one tile and without replacing it, total no. tiles become n = 6
Tile having multiples of 4 = 8, 20
No. of tiles having multiples of 4 = 2
Probability of choosing a second tile with multiple of 4 = 2/6
Total probability (first tile less than 7, second tile multiple of 4) = (2/7) · (2/6) = 4/42 = 2/21

What is the smallest and largest perimeter of a polygon with an area of 20?
Answer:
The polygon with the smallest perimeter is the megagon
The polygon with the largest perimeter is the triangle
Step-by-step explanation:
An equilateral triangle with area = 20 has
0.5× a²×sin60 = 20
a= 6.796
Hence, perimeter = 20.39
A square of area 20 has perimeter= 4×√20 = 17.9
A regular pentagon of area = 20 has perimeter = 3.41 × 5 = 17.05
Hence as the number of sides is increasing, the ratio of the Area to the Perimeter also increases
Therefore, a triangle has the largest perimeter with an area of 20 while a megagon with a million sides has the smallest perimeter with an area of 20.

(q^4)^z=q^12
find the value of z
Answer:
z = 3
Step-by-step explanation:
Using the rule of exponents
[tex](a^{m}) ^{n}[/tex] = [tex]a^{mn}[/tex]
Thus
[tex](q^{4}) ^{z}[/tex] = [tex]q^{4z}[/tex] , so
[tex]q^{4z}[/tex] = [tex]q^{12}[/tex]
Since the bases on both sides are equal then equate the exponents
4z = 12 ( divide both sides by 4 )
z = 3
Answer:
The value of z is 3.
Step-by-step explanation:
You have to use Indices Law,
[tex] {( {a}^{m}) }^{n} \: ⇒ \: {a}^{mn} [/tex]
So for this question, first you have to get rid of brackets :
[tex] { ({q}^{4} )}^{z} = {q}^{12} [/tex]
[tex] {q}^{4z} = {q}^{12} [/tex]
Next you can solve it since both have the same bases :
[tex] {q}^{4z} = {q}^{12} [/tex]
[tex]4z = 12[/tex]
[tex]z = 3[/tex]

0 24 and 25
O 27 and 25
O 23 and 26
Answer:
Option B, C and E are supplementary angles.
Step-by-step explanation:
We need to find supplementary angles.
Supplementary angles are those angles who sum up to 180 °.
I have attached picture for reference.
Looking at the figure given:
We have supplementary angles:
∠4 and ∠3
∠4 and ∠5
∠5 and ∠6
∠7 and ∠8
∠3 and ∠6
But the options given are: ∠4 and ∠3,∠4 and ∠5, ∠3 and ∠6
So, Option B, C and E are supplementary angles.
Supplementary angles are pair of adjacent angles that add up to 180 degrees
Conditions for supplementary anglesFor a pair of angles to be supplementary, then the following must be true
The angles must be adjacent i.e. side by sideThe angles must add up to 180 degreesThe image is not given.
So, I provided a general explanation

Answer:
Option (2)
Step-by-step explanation:
Measure of angle formed by two tangents from a point outside the circleis half the difference of the measures of the intercepted arcs.
From the figure attached,
m∠C = [tex]\frac{1}{2}[m(\text{major arc AB})-m(\text{minor arc AB)}][/tex]
= [tex]\frac{1}{2}[(360-m\widehat{AB})-m(\widehat{AB})][/tex]
= [tex]\frac{1}{2}[360-2m(\widehat{AB})][/tex]

= 180 - 150
= 30°
Therefore, measure of angle C will be 30°.

Answer:
-9.88.
Step-by-step explanation:
1. Write it out.
4.25-x=14.13
2. Make it a bit easier to read.
4.25-x=14.13 is also the same thing as... -x+4.25=14.13. Now it's easier to tell that 4.25 is positive.
3. Isolate x and get it by itself.
Since we have a number on x's side, we have to move it to the other side. The opposite of addition is subtraction, so we subtract 4.25 by both sides!
-x+4.25=14.13
-4.25 -4.25
-x=9.88
Technically, x can't really be negative, so we can just divide by negative one on each side to get rid of the negative x.
-x=9.88
/-1 /-1
x=-9.88
That's finally the answer and sorry if the explanation took forever! Hope you understand :)
A cylinder of base radius 4cm is opened at one end . If the ratio of the area of it's base to that of it's curved surface area is 1:4, Calculate the height of the cylinder
Answer:
Height = 8cm
Step-by-step explanation:
I hope it helps
The required height of the cylinder is 8cm.
A cylinder of base radius 4cm. The ratio of the area of it's base to that of it's curved surface area is 1:4. Height of cylinder is to be determine.
Surface area is defined as the area of the surface that are uncovered.
Here,
area of circle/surface area of cylinder=1/4
πr²/2πrh=1/4
r/2h=1/4
h=2r
where r = 4cm
h = 2*4
h = 8cm
Thus, the required height of the cylinder is 8cm.
