Radius = sqr v/(pi * h)
Radius = sqr 401.92/(3.14 * 2)
Radius = sqr 401.92/6.28

Twenty percent of the students received an A on the last math test. How many students received an A? / Jean Junction is selling jeans at 15% off the regular price. The regular price is $25.00 per pair. What is the discount?/ if you can answer these Ill do another 100 points but please I really need help

Answers

Answer 1↷

Given that ,

The sweater shack is offering 20% discount,

and the regular price is $ 15 .00,

so, the discount given would be

⇢ $ 15 x 20/100

⇢$ 15 x 0.2

⇢$ 3

selling price

⇢Regular price - Discount price

⇢$15 - $(20/100 x 15)

⇢$15 - $3

⇢$12

Answer 2

Given that,

20% out of 30 students scored an A in previous math test,

so ,the number of students who got an A in the test

⇢ 30 x 20/100

⇢30 x 0.2

⇢6

Hence ,6 students secured an A grade in last math test

Answer 3↷

Given that,

The Jean junction is selling the jeans at the discount rate of 15% of the regular price which is $25.00,

so, the discount is

⇢$25.00 x $ ( 15/100 )

⇢$25.00 x $ 0.15

⇢$3.75

selling price

⇢ $25.00 - $25.00 x $ ( 15/100 )

⇢$25.00- $25.00 x $ 0.15

⇢$25.00 -$3.75

⇢$21.25

My teacher keeps adamantly telling me that the answer is D, and I insist it’s B. Am I right or is she right?


My reasoning, question asks for an ALWAYS true statement. Question gives 6 defined points that if plotted will show it will need to cross the x axis twice to connect all the points while being continuous. Yet functions aren’t always straight and simple so two is the bare mininum and there may be more as in between those defined points the line may have crossed multiple times. However D and C assume its exactly 2 or more than 2, therefore they are wrong. If D and C merged together then that would be better than B. Yet B is still correct on the terms of being an “always” correct statement.

Answers

the picture below is more or less some quick mockup of what that might be, and yes, 2 solutions or zeros is the bare minimum, because we know only 5 points on this continuous line, but it could have jumped a few times before going forwards and we are not privy to those points.

well, we can say that

f(x) has more than one zero

f(x) has exactly two zeros

I think within the circumstance both are acceptable, exactly 2 zeros is also acceptable, but is not exclusively the only valid choice, if any we could say "exactly 2 zeros" is a subset of the superset "more than one zero".

kinda like saying Sandra has Felines and she also has 3 cats, well, 3 cats are an exact number, but the plural Felines contains them, so both statements are equally valid, one is more general than the other, is all

Answer:

The Distance from the center ( B ) of the smaller circle to its edge is the radius of the circle therefore  length BD = length AB

From the given diagram

The center of the bigger circle is at C while

The center of the smaller circle is at point B .

The smaller circle cuts through the bigger circle creating two segments BD and AB which starts from the middle of the smaller circle to the intersecting edges of the circles.

Hence the length of segment BD = length of segment AB because they both start from point B .

You and your friend join a new gym that requires a one-time joining fee and monthly payments. Your friend chooses the 1 year plan and pays $687, while you elect the 18 month contract which costs $981. Use this information to determine the linear model used to calculate cost from months of membership.

Answers

Answer:

C = 99 + 49m

x = $99

y = $49

Step-by-step explanation:

Let

x = one time joining fee

y = monthly payment

Your friend:

1 year = 12 months

x + 12y = $687

You:

x + 18y = $981

x + 12y = 687 (1)

x + 18y = 981 (2)

Subtract (1) from (2)

18y - 12y = 981 - 687

6y = 294

Divide both sides by 6

y = 294 /6

= 49

x = $49

Substitute y = 49 into

x + 12y = 687

x + 12(49) = 687

x + 588 = 687

x = 687 - 588

= 99

x = $99

C = 99 + 49m

Where,

C = total charges

m = number of months

99 = a one time joining fee

49 = charges per month

The length of Rectangle A is 5 inches more than its width. The perimeter of Rectangle B is 17. The difference between the perimeters of the rectangles is less than 9. What are the possible integer values for the width of Rectangle A?

Answers

Based on the perimeter value, the width of the rectangle is 1.75 inches

What are perimeters?

The perimeter of a shape is the sum of the side lengths of the shape

For all regular quadrilaterals, you add up the side lengths to determine the perimeter

How to determine the width of the rectangle?

The given parameters about the rectangle are

Perimeter = 17

Length = Width + 5

Rewrite the above equations as

l = w +  5

p = 17

The perimeter of a rectangle is

p = 2 x (l + w)

Substitute p = 17 in the above equation

So, we have

2 x (l + w) = 17

Substitute l = w+ 5 in the above equation

So, we have

2 x (w + 5 + w) = 17

Evaluate the like terms in the above equation

So, we have

2 x (2w + 5) = 17

Open the bracket in the above equation

So, we have

4w + 10 = 17

Evaluate the like terms in the above equation

So, we have

4w = 7

Divide both sides of the above equation by 4

So, we have

w = 1.75

Hence, the width of the rectangle is 1.75 inches

Samantha is taking out a loan for $17,452 at 6% simple interest for one year. How much interest will she pay?

Answers

Answer:

She will pay $1,047.12 interest for one year

Step-by-step explanation:

Simple Interest

Occurs when interest is calculated on the original principal only.

Unlike compound interest where the interest earned in the compounding periods is added to the new principal, simple interest only considers the principal to calculate the interest.

The interest earned is calculated as follows:

I=P.r.t

Where:

I = Interest

P = initial principal balance or loan

r = interest rate

t = time

Samantha takes out a loan for $17,452 at r=6%=0.06 simple interest for t=1 year. Calculating the interest:

[tex]I=\$17,452*0.06 *1[/tex]

I = $1,047.12

She will pay $1,047.12 interest for one year
