They could have biked on first day at the speed of x/4 miles per hour and on the second day at the speed of (88-x)/6 miles per hour where x is the distance covered on first day.

According to the question,

We have the following information:

Jaden and Emilia biked 88 miles from Daytona Beach to Jacksonville in 2 days. They spent 4 hours biking the first day and 6 hours biking the second day. They biked at one speed the first day and a different speed the next day.

Now, let's take the distance covered on first day to be x miles.

Distance covered on second day = 88-x miles

Following formula is used to find the speed of an object:

Speed = distance/time

Speed of first day = x/4 miles per hour

Speed of the second day = (88-x)/6 miles per hour

Hence, they could have biked on first day at the speed of x/4 miles per hour and on the second day at the speed of (88-x)/6 miles per hour where x is the distance covered on first day.

The mean age (nearest year) of all the people in the office is 22.4.

Age for women

Age = 12 women × 22 years old / 12

Age = 264 /12

Age = 22

Age for men

Age = 3 men × 24 years old / 3

Age = 72/3

Age = 24

Now let find the mean age

Mean age = Sum of men and women age / Number of men and women

Mean age = 264 + 72 / 12 +3

Mean age = 336 /15

Mean age = 22.4

Therefore the mean age is 22.4.

Hey there! I would be glad to help you out.

For the first two miles, the price would be six dollars total.

For every mile after that, you would be charged two dollars.

Assuming that you travel 8 miles, you would have to pay six dollars for the first two miles (3*2), and twelve dollars for the last six miles, totaling eighteen dollars.

So the price of an eight mile ride would be eighteen dollars.

You can use this logic for the 50 miles trip too. After traveling 2 miles ($6), there will be 48 more miles.

For these 48 miles, it'll only charge you two dollars each, which would total 96 dollars.

So the price of a fifty mile ride would total $102.

The number of short sleeves that Maria sold is 819.

Ratio demonstrates how many times one number can fit into another number. Ratios contrast two numbers by ordinarily dividing them.

In this case, Maria’s clothing store sold 1547 shirts with the ratio of short sleeve to long sleeve shirt being 9:8.

The number of short sleeves will be:

= Ratio for short sleeve / Total ratio × Total number of clothes

= 9 / (8 + 9) × 1547

Grocer will mix 20 pounds of the kenyan beans $8.25per/lb one and another 30 pounds of the venezuelan beans $9.50per/lb one.

Let's x be the kenyan beans that sell for $8.25 per pound and y be venezuelan beans that sell for $9.50 per pound.

Altogether there are 50 pounds of beans.

The algebraic equation would be x + y = 18.

At $9.00 per pound, he will make 50 * $9.00 = $ 450.0

So, how many of the x and y kinds of coffee should he use to make the $9.00 per pound mixture which will net him $450.0.

The algebraic equation would be 8.25x + 9.50y = 450

We now have two equations

x + y = 50 --(i)

8.25x + 9.50y = 450 --(ii)

Substituting x= 50 - y in the second equation gives us

8.25(50-y) + 9.50y = 450

412.5 - 8.25y + 9.50y = 450

1.25y = 450 - 412.5

1.25y = 37.5

y = 30

Substitute the value of y in equation(i)

x + y = 50

x = 50 - 30

x = 20

Hence, Grocer will mix 20 pounds of the kenyan beans $8.25per/lb one and another 30 pounds of the venezuelan beans $9.50per/lb one.

Step-by-step explanation:

Edmentum it's right.

In the year 2018, the amount that Chase owes in federal income taxes is $16, 280.70

In 2018, Chase earned $91, 630 which put him in the 24% tax bracket. Here, his tax is $14,089.50 plus 24% of every dollar above $82,500.

The amount that Chase made above $82, 500 is:

= 91, 630 - 82, 500

= $9, 130

The federal income tax that Chase owes is therefore:

= 14, 089.50 + (9, 130 x 24%)

= 14, 089.50 + $2, 191. 20

Answer: $16,280.70

Step-by-step explanation:

First, find the difference between $91,630 and $82,500 to find the amount that is taxed at the 24% tax rate.

$91,630−$82,500=$9,130

Now, multiply $9,130 by 24% to find the additional amount of tax.

$9,130⋅24%=$2,191.20

Add $2,191.20 to $14,089.50 to find the total amount of federal income taxes Chase owes.

$2,191.20+$14,089.50=$16,280.70

Therefore, Chase owes $16,280.70 in federal income taxes for 2018.

What is z-sore ?

The z-score of a value is the count of the number of standard deviations between the value and the mean of the set. You can find it by subtracting the value from the mean and dividing the result by the standard deviation.

Here given that,

The value of x in the polygon is 9

A heptagon is a polygon that has seven sides. It is a closed figure having 7 vertices. A heptagon is also sometimes called Septagon.

In Geometry, the shape that is bounded by at least three straight lines or at least three interior angles is called polygon. The most common examples of polygons are

Triangle ( 3 sided polygon)

Quadrilateral ( 4 sided polygon)

Pentagon ( 5 sided polygon)

The polygon is a heptagon with number of sides n = 7

sum of interior angles of a polygon = (n - 2) x 180

if n = 7,

Sum of the interior angles = (7 -2) x 180

                                            = 5 x 180

                                            = 900

summing all the angles in the given polygon, we have

135 + 3x + 31 + 4x + 15 + 6x - 8 = 120 + 7x - 64 + 5x - 4 = 25x + 675

25x + 675 = 900

25x = 900 - 675

25x = 225

x = 225/25

x = 9

According to the concept of unitary method, the number of pennies are 6.

Unitary method:

The process of finding the value of a single unit, and based on this value is called as unitary method.

Given,

Out of 150 coins, 90 are quarters. Of the remaining coins, 40% are nickels and the rest are dimes and pennies. There are 5 dimes for every penny.

Here we need to find the number of pennies in the coins.

Here we know that the total number of coins are 150, thus includes

=> Quarters + nickels + dimes + pennies = 150 

Here the number of Quarters are 90 

Therefore, the remaining coins are calculated as,

=>  150 − 90 = 60

Here the percent of nickels is 40, then the number of nickels is

=> 60x 40/100

=> 24 numbers

Now, the remaining coins such as dimes and pennies are

=> 60 − 24 = 36 numbers.

Here we know that, in (5 + 1) = 6 coin of dimes and pennies there is 1 penny

So, in 36 coin of dimes and pennies there are,

=>36 / 6

=> 6 

Therefore, there are 6 pennies.
