Dominic Needs A New Bike Mirror His Old Mirror Was A Square With A Side Length Of 9cm He Wants The New

Answers

Answer 1

Answer:

If his old mirror had a side length of 9cm, that means the area would be 81cm (9 times 9)

For the circles:

A radius of 8: 201.06

A radius of 7: 153.94

A radius of 5: 78.54

The only one of these answers that is remotely close to dominics original mirror would be C: the radius of 5. 81 is close to 78.5!

Suppose you want to buy a $151,000 home. You found a bank that offers a 30-year loan at 4.7% APR. What will be your monthly payment? (Round to the nearest cent.)

Answers

Answer:

the monthly payment is $783

Step-by-step explanation:

The computation of the monthly payment is shown below:

Given that

PV = $151,000

NPER = 30 × 12 = 360

RATE = 4.7% ÷ 12 = 0.39166

FV = $0

The formula is shown below

= PMT(RATE;NPER;-PV;FV;TYPE)

AFter applying the above formula, the monthly payment is $783.14

A biologist was studying a certain species of earthworm. She collected samples of 6 adults from 2 different populations and measured their lengths in centimeters. The data are shown below.

Sample 1: 26, 25, 27, 19, 24, 26

Sample 2: 24, 23, 24, 26, 25, 25

Compare the means and ranges of the data for the 2 samples. Use your comparison to conclude the samples. Show and explain your work.
CAN YOU EXPLAIN WHY ALSO CAN YOU DO THIS AS SOON AS POSSIBLE PLEASE AND THANK YOU?

Answers

Answer:

Calculating the means:

Sum each length from each sample and divide it by the number of worms.

Sample 1: 26 + 25 + 27 + 19 + 24 + 26 = 147/6 = 24.5

Sample 2: 24 + 23 + 24 + 26 + 25 + 25 = 24.5

They each have the same sample mean.

Ranges: Take the largest length and subtract the smallest.

Sample 1: 27 - 19 = 8

Sample 2: 26 - 23 = 3

Sample 1 has a greater range.

Find the values of x and y. Write your answers in simplest form.

Answers

Step-by-step explanation:

You have this rule, if there is < 30° then value of y is

y=12✓3:2

y=6√3

And Pitagora's theorem:

c²=a²+b²

In this case:

(12√3)²=y²+x²

Then x is:

x²= (12√3)²-y²

x²= (12√3)²-(6√3)²

x²=432- 108

x²= 324

x=✓324

x=18cm

QUESTION 8 of 10: Juanita, the stadium manager, spends $10,000 on a broadcast TV ad, $15,000 on a cable TV ad, and $4,000 on a radio ad
What percentage of radio advertising did she do? (Round to the nearest percent.)

Answers

Answer: 13.79%

Step-by-step explanation:

Amount spent on broadcast TV advertisement = $10000

Amount spent on cable TV advertisement = $15000

Amount spent on radio advertisement = $4000

Total amount spent advertisement = $10000 + $15000 + $4000 = $29000

The Percentage of radio advertisement done will be:

= (Amount spent on radio advertisement / Total amount spent advertisement ) × 100

= (4000 / 29000) × 100

= 13.79%

Answers

Answer:

A + B + C + D = 52.35

Step-by-step explanation:

Here, we want to get the sum of A, B , C and D

from the question, s represents the number of small candies

L represents the number of large candies

Let us start with the cost;

small candies cost 10 cents; that is same as 10/100 = $0.1

large candies cost 25 cents, that is same as 25/100 = $0.25

so therefore, A is 0.1 and B is 0.25

C and D represents the total number of candies bought and that is 52

So, the sum of A, B , C and D is ;

0.25 + 0.1 + 52 = 52.35

A stage in the shape of a semi circle had a diameter of 42 ft. What is area of the stage? Use 22/7 for π. PLZ I NEED FAST TEST

Answers

A semi circle is half a full circle. Find the area of the full circle and divide it by 2.

Area of a circle = pi x r ^2

R is half the diameter

Area of full circle:

Area = 22/7 x 21^2

Area = 1386 sq. Ft

Area of stage = 1386/2 = 693 square feet

Answer:

3.14 x 42 x 42 = 5538.96ft

If your wondering why used 3.14 instead of 22/7 is because they are exactly the same just one is a whole number and the other is a fraction. I suggest you use 3.14 because its easier than 22/7.
