A grocery store sells a store-made brand of raisin bran in bulk (by the pound). The store sells this mixture for $3.14 per pound. When the store mixes its raisin bran, the employees use raisins that are $4.50 per pound and bran flakes that are $2.80 per pound. If the store makes 50 pounds of raisin bran, how many pounds or raisins and bran flakes does the store need?
Answer: quantity of raisins = 10 pounds, quantity of bran flakes = 40pounds.
Step-by-step explanation:
Let r= quantity of raisins, b = quantity of bran flakes.
As per given,
r+b=50 (i)
4.50r + 2.80b= 3.14(50)
⇒4.50r + 2.80b=157 (ii)
Multiply (i) by 2.80, we get
2.80r+2.80b=140 (iii)
Now, subtract (iii) from (ii), we get
1.7r = 17
⇒ r= 10
Put this in (1), we get
[tex]10+b=50\Rightarrow\ b= 40[/tex]
Hence, quantity of raisins = 10 pounds, quantity of bran flakes = 40pounds.
Find the slope of the line.

a deli charges 5 for a sandwich and 2 for a drink in one day the deli made 230 selling a total 55 sandwiches and drinks . how many drinks were sold at the deli that day
Answer: 15
Step-by-step explanation:
Let the number of sandwich sold be a
Let the number of drinks sold be b
The following can be formed as.an equation from the question:
5a + 2b = 230 ....... i
a + b = 55 ....... ii
Multiply equation i by 1
Multiply equation ii by 5
5a + 2b = 230 ........ iii
5a + 5b = 275 ........ iv
Subtract iv from iii
-3b = -45
b = 45/3
b = 15
The number of drinks sold were 15

Find the measures of the numbered angles in the following rectangle.
The measures of Angle 1 is 29 degrees, Angle 2 is 61 degrees, Angle 3 is 90 degrees, Angle 4 is 29 degrees, Angle 5 is 90 degrees.
What is Triangle?A triangle is a three-sided polygon that consists of three edges and three vertices.
In the given figure there are two right angle triangles.
By angle sum property, the sum of three angles is 180 degrees.
Now let us find angle 4
61+angle 4=90
Angle 4=90-61
Angle 4 =29 degrees
Now let us find angle 1
Angle 5 is 90 degrees.
61+90+Angle 1= 180
151 + Angle 1=180
subtract 151 from both sides
Angle 1=180-151
Angle 1 is 29 degrees.
Now let us find angle 2
Angle 1+ Angle 2 =90
29+ Angle 2=90
Angle 2=90-29
Angle 2 is 61 degrees.
Angle 3 is 90 degrees.
Hence, the measures of Angle 1 is 29 degrees, Angle 2 is 61 degrees, Angle 3 is 90 degrees, Angle 4 is 29 degrees, Angle 5 is 90 degrees.

a. Write a system of equations that is equivalent to this system. Describe what you
did to the original system to get the new system.
b. Explain how you know the new system has the same solution as the original
system.
The new system of equations is 2p + 16q = -16 and p + 10q = -10, and they have the same solution with the old because it can be converted
A new system of equationsThe system of equations is given as
p + 8q = -8
1/2p + 5q = -5
To generate a new system of equations, we can multiply the old equations by 2
So, we have the following computations
2(p + 8q = -8)
2(1/2p + 5q = -5)
Evaluate the products
2p + 16q = -16
p + 10q = -10
Why they would have the same solutionsThey would have the same solutions because the new equations can be converted to the old equations
This is done by dividing the new equations by 2

A police car drives at a constant speed of 108 km/h. How long will it take to travel a distance of
378 kilometers?
Answer:
3 hours 50 minutes
Step-by-step explanation:
since speed equals distance multiplied by the time taken, using the same formula time taken will be the distance divided by the speed. so 378kilometres divided by the 108 kmper hour you get the answer 3 hours 50 minutes

Hector solves and equation by subtracting 8 from both sides of the equation. Then he multiples both sides of the equation by 3. The result is m=15. What was the original equation? How do you know?
Given:
The result is [tex]m=15[/tex].
To find:
The original equation.
Solution:
We need to apply the opposite operations from bottom to top in the resultant equation to get the original equation.
It means opposite operation of last operation will be applied first.
We have,
[tex]m=15[/tex]
Divide both sides by 3.
[tex]\dfrac{m}{3}=5[/tex]
Add 8 on both sides.
[tex]\dfrac{m}{3}+8=5+8[/tex]
[tex]\dfrac{m}{3}+8=13[/tex]
Therefore, the original equation is [tex]\dfrac{m}{3}+8=13[/tex].

Answer:
1: A because the proportions are off
2: yes, since the second and third hippos are both 4 feet tall, however one of them looks different. we know that the first and last hippos are not distorted because their proportions are equal, but the second one is much wider with a very different body shape, and looking at the original, we can easily tell that the ratio is incorrect. also, the color is very different from the original.

Step-by-step explanation:
We are going to solve the system by subtracting one equation from another in this case the second from the first.
Now we are going to divide 30 by 6 which will give you the value of x.
Now we will substitute x into one of the equations to solve for y.
Now we multiplied 6 by 5.
Now we will subtract 30 from 60 giving you the value of 2y.
Now you divide 30 by 2 giving you the value of y.
Now check you answers by inserting the values you got for x and y into one of the original .

Answer:
x = 16, y = 10
Step-by-step explanation:
(8x - 14) and (5x + 34) are alternate exterior angles and congruent, thus
8x - 14 = 5x + 34 ( subtract 5x from both sides )
3x - 14 = 34 ( add 14 to both sides )
3x = 48 ( divide both sides by 3 )
x = 16
Then
8x - 14 = 8(16) - 14 = 128 - 14 = 114
(5y + 16) and (8x - 14) are adjacent angles and supplementary, thus
5y + 16 + 114 = 180 , that is
5y + 130 = 180 ( subtract 130 from both sides )
5y = 50 ( divide both sides by 5 )
y = 10

Which situation could NOT represent a proportional relationship? * The amount an employee who makes $9.50 per hour earns in h hours The cost of purchasing p pounds of bananas for $0.36 per pound The weight in x weeks of a puppy that gains 4 pounds per week if its starting weight is 16 pounds The number of gallons of water in x barrels with 33 gallons of water in each barrel
Answer:
The weight in x weeks of a puppy that gains 4 pounds per week if its starting weight is 16 pounds
Step-by-step explanation;
Let us analyze the option one after the other
1. "The amount an employee who makes $9.50 per hour earns in h hours"
This represents a proportional relationship, because for the more the employee works the more he earns
2. "The cost of purchasing p pounds of bananas for $0.36 per pound"
This represents a proportional relationship, because the more the pound the greater the cost
3. "The weight in x weeks of a puppy that gains 4 pounds per week if its starting weight is 16 pounds"
This is not because there was an existing 16 pounds, although it will get to a point where the relationship becomes a proportional relationship.
4. "The number of gallons of water in x barrels with 33 gallons of water in each barrel"
This is a proportional relation, because more barrels will contain more gallons of water.

What is the equation in the slope-point form of the line that passes through the points (-5,-9) and (7,9) A. y - 9=1.5(x - 5) B. y + 9=1.5(x - 7) C. y - 5=1.5(x + 9) D. y - 9=1.5(x - 7)
Answer:
D. y - 9 = 1.5(x-7)
Step-by-step explanation:
First find the slope using this formula. y2-y1/x2-x1
Plug in with (-5, -9) & (7, 9)
9-(-9)/7-(-5) = 18/12 (simplify)
18/12 ÷ 3 = 6/4 ÷ 2 = 3/2
The slope is 3/2 or 1.5
To find the y-intercept plug in one of the points (7, 9)
9 = 3/2(7) + b (b represents the y-intercept)
9 = 10.5 + b
-1.5 = b
The equation is y = 1.5x - 1.5
A. y = 1.5x + 1.5
B. y = 1.5x - 19.5
I'll just skip C the answer is D I'll show the work
y - 9 = 1.5(x-7) (distribute 1.5 to x and -7)
y - 9 = 1.5x - 10.5 (add 9 on both sides)
y = 1.5x - 1.5
