FIRST
We need to make a comparison for peanuts and raisins they need.
peanuts : raisins = 1 3/8 : 2/3
peanuts : raisins = 11/8 : 2/3

Simplify the ratio so it's not on a fraction form
peanuts : raisins = 11/8 × 3/2
peanuts : raisins = 33 : 16
For 33 pounds of peanuts, we need 16 pounds of raisins

SECOND
Calculate the need of peanuts using ratio above
the sum of ratio = 33 + 16 = 49

need of peanuts = ratio of peanut/sum of ratio × sum of pounds
need of peanuts = 33/49 × 245
need of peanuts = 8,085/49
need of peanuts = 165

They need 165 pounds of peanuts to make 245 pounds of trail mix

14. Two cars are traveling on two different roads that are perpendicular to each other. On a coordinate
Klio2033 [76]

Answer:

-68/7

Step-by-step explanation:

slope1 of Car 1 that pass (-5,-8) (2,7)

= (y1-y2)/(x1-x2)=(2-(-5))/(7-(-8))=7/15

Slope2 of car 2 that pass (5,1) (10,y)

slope 1 and slope2 are perpendicular =>slope 2 =-15/7

make slope2 y=(-15/7)x+b

for it pass(5,1) => 1=(-15/7)5+b =>b=82/7 => y=(-15/7)x+82/7

put (10,y) in => y=(-15/7) 10+82/7=-68/7

The two-way table below describes the quality of sweatshirts and T-shirts screen printed at a local store.
zhuklara [117]

Answer:

There is an association because the relative frequencies by row are different.

Step-by-step explanation:

The relative frequencies by row are:

90 perfect t-shirts out of 90+6=96 t-shirts is:

90/96 = 0.9375

6 flawed t-shirts out of 96 t-shirts is:

6/96 = 0.0625

40 perfect sweatshirts out of 40+10=50 sweatshirts is:

40/50 = 0.8

10 flawed sweatshirts out of 50 sweatshirts is:

10/50 = 0.2

The relative frequencies by row are different; this means there is an association.

How many solutions exist for the system of equations graphed below?<br><br> Help please !
kiruha [24]

Answer:

none (0) ...

think of two lines (or chop sticks places on a table) ...

there are three (3) possible orientations that they can be in.

1) they cross each other at one point

2) they are on top of each other (they touch everywhere)

3) they are side by side (parallel)

in situation one we say we have a solution

in situation two we say there is an infinite solutions (the same line)

in situation three (your problem) we say there is no solution (parallel lines)

What is the length of the longest side of a triangle that has vertices at (7, 6), (7, 1), and (-5, 6)?
iren2701 [21]

Answer: The Answer is going to be B.

Step-by-step explanation:

We can find the distance between each pair of points using the distance formula Sqrt((x1-x2)^2 + (y1-y2)^2),(x1 and x2 are the x ordinates of each point, and y1 and y2 are the y ordinates. Sqrt stands for square root, and ^2 is to the power of two.

Using this we can find the side between 7,6 and 7,1 is 5.

The side between 7,1 and -5,6 is 13

The side between 7,6 and -5,6 is 12

After using the formula we can conclude the side between 7,1 and -5,6 is the longest, and it equals 13. Therefore the answer is B.

Darla spent $120.37 on groceries in January, $108.45 in February, and $114.86 in March. What was the average monthly cost of Dar
kari74 [83]
In order to find an average, you have to add all the numbers and divide by the number of things you added.

120.37 + 108.45 + 114.86 = 343.68
343.68/3 = 114.56

She spent an average of $114.56 each month on groceries.
