The interest earned by Ryan is $131.44  and the interest earned by Brian is $32.86    .

In the question,

it is given that

amount deposited by Ryan = $775

time for which the amount is deposited = 4 years

rate at which the amount is deposited = 4.24%

So the simple interest = (p*r*t)/100

= (775 * 4.24*4 ) /100

= 13144/100

= 131.44

amount deposited by Brian = $775

time for which the amount is deposited = 1 years

rate at which the amount is deposited = 4.24%

So the simple interest = (p*r*t)/100

= (775 * 4.24 * 1 ) /100

= 3286/100

= 32.86

Therefore , the interest earned by Ryan is $131.44  and the interest earned by Brian is $32.86    .

The given question is incomplete , the complete question is

Ryan deposits $775 in an account that pays 4.24% simple interest for four years. Brian deposits $775 in an account that pays 4.24% simple interest for one year. Find the interest earned by both Ryan and Brian ?

The cost or unit price for purchasing each pair of work gloves is $1.19.

The cost of 7 dozen pairs of padded work gloves purchased by the contractor is $99.96.

The incorrect unit price calculated by the contractor is $14.28 per pair.

Now, we know 1 dozen is equal to 12 units.

Therefore,

The number of pairs of gloves purchased = 7 × 12 = 84

As the total cost is $99.96, the cost of each pair will be:

= $99.96 ÷ 84

= $1.19

The error by the contractor was that she didn't consider the word dozen in his calculation. She simply divided the total cost by 7 to calculate the price per pair.

The unit price of purchasing each pair of work gloves is $1.19.

Yoona will charge $20.75 to walk 8 dogs based on the trend of Yoona charges to walk dogs.

First, find the pattern in the amount that Yoona charges to walk each additional dog.

Additional cost to walk 2 dogs:

= 40 - 37.25

= $2.75

Additional cost to walk 3 dogs:

= 37.25 - 34.50

= $2.75

Additional cost to walk 4 dogs:

= 34.50 - 31.75

= $2.75

Every extra dog therefore leads to a fall in price by $2.75. For eight dogs, Yoona would charge:

= 40 - (7 x 2.75)

= 40 - 19.25

= $20.75

Step-by-step explanation:

Using exponent properties, we can rewrite the expression using a single whole-number exponent as:

(0.25³)⁵  = 0.25¹⁵

Here we have the numerical expression:

(0.25³)⁵

Here we need to use the exponent property:

(xᵃ)ᵇ = xᵃ*ᵇ

Using that in our expression, we will get:

At the unit rate of reading 93.5 books in 8.5 months, Annarose expects to read 132 books annually.

The unit rate is the ratio or speed that Annarose reads books.

From her established unit reading rate, she reads 11 books in a month.

The unit rate is computed by ensuring that the denominator becomes 1 after the division operation.

The number of books she read in 8.5 months = 93.5 books.

The number of books she can read in 1 month = 11 books (93.5/8.5).

The number of books she can read in 12 months = 132 books (11 x 12).

Thus, given Annarose's reading unit rate, she expects to read 132 books annually, at an average of 11 books every month.

The approximate perimeter of the entire shape is 50.27 inches.

The perimeter of a figure is the sum of the whole sides of the figure.

Therefore, the perimeter of the entire shape can be calculated as follows:

The shape is made of three sides of a square and half a circle.

Therefore,

circumference of the semi circle = πr

r = 11 / 2 = 5.5 inches

circumference of the semi circle = 5.5π

Hence,

perimeter of the shape = 11 + 11 + 11 + 5.5π

perimeter of the shape = 33 + 5.5(3.14)

perimeter of the shape = 33 + 17.27

Answer:

148              

Step-by-step explanation:

The triangle are similar because the angle measurements are the same.  

180-51-34 = 95

180-95-51 = 34

If we match up the corresponding sides we see that the side with 45 corresponds to the side with 36.  Now we need to find the scale factor.

Let s = the scale factor

45s = 36  Divide both sides by 45

s = .8

This means that the corresponding length of the triangle on the right is .8 of the triangle on the left.

The corresponding side to x is 79, so 79 x .8 = 63.2.  Now that we know the three sides we can add them together to find the perimeter.

63.2 + 36 + 48.8 = 148

The balance in the account at the end of two years is $864.

The interest earned by Suki during that time is $64.

The initial principal amount "P" is $800.

The interest rate "R" is 4%.

The interest is compounded quarterly.

This means the value of "n" is 4.

The time period for which the interest is earned is 2 years.

The formula for compound interest is :

A = P*[1 + (R/n)]^(n*t)

A = 800*[1 + (0.04/4)]^(4*2)

A = 800*[1 + 0.01]^(4*2)

A = 800*[1.01]^(8)

A = 800*1.08

A = 864

The total interest earned is the final amount minus the principal amount.

The total interest earned is $864 - $800.

The total interest earned is $64.

f(x) = 12x - 3

First, replace f(x) with y:

y = 12x - 3

Now, make x the subject of the function:

y + 3 = 12x

Now, replace x with f-1(x) and y with x:

That is the inverse function.

The correlation coefficient between the number of volunteers x and the number of bags of trash collected y, so the percentage of variation in the number of bags of trash collected is 92.92 %.

You may gauge how closely two variables are related by looking at their correlation coefficients. Pearson's correlation coefficient is the most often used of the several correlation coefficient types. Often employed in linear regression, Pearson's correlation (also known as Pearson's R) is a correlation coefficient. It's likely that you'll learn about Pearson's R first if you're just getting started in statistics. Actually, Pearson's is typically mentioned when someone mentions the correlation coefficient.

According to the question,

The correlation coefficient i.e., r between x and y is 0.964.

r = 0.964

Squaring on both sides :

r² = 0.964²

r² = 0.9292

Now, convert this into percentage form by multiplying it will 100.

⇒0.9292 × 100

= 92.92 %.

Hence, the percentage of the variation will be 92.92 %.
