a grocer wants to mix kenyan beans that sell for $8.25 per pound with venezuelan beans that sell for $9.50 per pound to form a 50 pound batch of beans that sells for $9.00 per pound. how many pounds of kenyan beans should go
into the blend?
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.

A student measured the length of a room and obtained the measurement of 3.99m. If the percentage error of his
measurement was 5% and his own measurement was smaller than the length, what is the length of the room?
A. 3.78m B. 3.80m C. 4.18m D. 4.20m
Answer:
D)
Step-by-step explanation:
Percentage word problems:Let the original length be 'x'.
Percentage error = 5 %
So, (100 -5)% = 95% of the original measurement is 3.99 m
95% of x = 3.99
[tex]\sf \dfrac{95}{100}*x = 3.99[/tex]
[tex]\sf x = \dfrac{3.99*100}{95}\\\\x = \dfrac{399}{95}\\\\\\x = 4.2 m[/tex]
Original length = 4.2 m
Find the slope, of m of the line that passed through the points (-2/3, 3/4) and (5/6, -1/2). Enter your answer as a fraction in simplest form in the box
m = (-1/2 - 3/4) / (5/6 - (-2/3))

Jaden and Emilia biked

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. At what speed
(miles per hour) could they have biked each day? Explain.
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.

A) 3
B) 4

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.

a driver charges $3 per mile for the first 2 miles, then $2 for each additional mile. if you traveled 8 miles, what would the total fee be? and if you traveled 50 miles, what would the total fee be?
PLEASE HURRY AND ANSWER!!!!! THIS PAPER IS DUE TOMORROW MORNING! AND ITS FOR A GRADE!!!!
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 value of x in the polygon is 9
What is a Heptagon?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

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.
