Answer:
<u>Tabatha needs 25 feet of additional feet of pink ribbon to complete all the hair bows.</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Amount of pink ribbon Tabatha has = 3 1/3 yards
Amount of pink ribbon Tabatha needs to make all the hair bows = 35 feet
2. How many more feet of ribbon will Tabatha need to complete all the hair bows?
1 yard = 3 feet
3 1/3 yards = 10 feet
Additional feet of pink ribbon Tabatha needs = Amount of pink ribbon Tabatha needs to make all the hair bows - Amount of pink ribbon Tabatha has
Additional feet of pink ribbon Tabatha needs = 35 - 10
<u>Additional feet of pink ribbon Tabatha needs = 25 feet</u>
The answer is 6/35, cross multiply
This is a system of equations problem:
Part one set up general equations
1) Peanuts = 3x ($3 per pound)
2) Jellybean = 1.5y ($1.50 per pound)
Relate x and y to the information you have
He wants 30lb. total: x + y = 30
He also wants the mixture to be valued at $2.50 per pound = 3x + 1.5y = 30(2.5)
*I'm taking $2.50 times 30 because you want the total cost to equal since he wants $2.50 per pound.
You want to substitute one equation into the other.
x + y = 30
3x + 1.5y = 75
1) x + y = 30 => x = 30 - y
2) 3(30 - y) + 1.5y = 75
3) 90 - 3y + 1.5y = 75
4) -1.5y = -15
5) y = 10lb.
Then plug that into one of the original equations to get x.
6) x+ y = 30 => 10 + x = 30 => x = 20lb.
He wants 20lb. of peanuts and 10lb. of jellybeans
Answer:
3/1
Step-by-step explanation:
The average rate of change is the distance between y values divided by the distance between x values. We know this as rise/run or slope for linear equations. For non-linear equations, we calculate the average over an interval.
This function has y-values of -1 at x=0 and 5 at x=2.
We add -1+5=6 and divide this by 2-0=2.
6/2=3.
The y-values on average change 3 units for every 1 unit of the x-values.
Ok so ... the answer is B:264 because you multiply all the numbers because volume = l x w x h... which also is 6 x 11 x 4 and that’s how I got B :)
