Patty can make 10 purses in 8 hours. At this rate, how many purses can she make in 28 hours?
Answers
Answer:
35 purses
Step-by-step explanation:
Set up a proportion, where x is the number of purses she can make in 28 hours:
[tex]\frac{10}{8}[/tex] = [tex]\frac{x}{28}[/tex]
Cross multiply and solve for x:
8x = 280
x = 35
So, in 28 hours, she can make 35 purses

Solve the formula for c.
b. The area of a rhombus is 35 square feet. The length of one of the diagonals is 10 feet. What is the length of the other diagonal?
c. In a square (which is a rhombus), the lengths of the diagonals are the same. If a square has an area of 32 square feet, then what is the length of each diagonal?

Answers
Answer: next three terms: a_5 = -20, a_6 = -23, a_7 = -26
Step-by-step explanation:
Formula: a_n = a_1 + (n-1)d
We need to find the 5th, 6th and 7th term.
a_5 = -8 + (5-1)(-3)
a_5 = -20
a_6 = -8 + (6-1)(-3)
a_6 = -23
a_7 = -8 + (7-1)(-3)
a_7 = -26

So i'm having difficulty understanding this "When multiplying the same base raised to an exponent __ the base and __ the exponents" Please help i do not understand this.
Answers
Answer:
When multiplying the same base raised to an exponent, keep the base and add the exponents.
Step-by-step explanation:
The exponent "product rule" tells us that, when multiplying two powers that have the same base, you can add the exponents. In this example, you can see how it works. Adding the exponents is just a short cut! The "power rule" tells us that to raise a power to a power, just multiply the exponents.

A ribbon is 5 4/5 yards long. Mae needs to cut the ribbon into pieces that are 4/5 of a yard long. How many pieces of ribbon can she cut?
Answers
The answer is 7 pieces.
If you divide 5.80 (5 4/5) by 0.80 (4/5), you get 7.25. Since Mae probably doesn't want to use a piece of ribbon smaller than the others she will only cut 7 pieces.
Answer:
7
Step-by-step explanation
5 4/5 = 5/5, 5/5, 5/5, 5/5, 5/5, 4/5
so five 5/5 - 1/5 each = 4/5, 4/5, 4/5, 4/5, 4/5 so we now have five 4/5 + the 4/5 we had at the beginning so we have six 4/5 then add all of the 1/5 we took away from all of the 5/5 so 1/5 x 5 = 5/5 = 4/5 Remainder 1/5 so we now have seven 4/5 and an extra 1/5
so, in conclusion, Mae can cut seven pieces of ribbon.

Answer:
c = 29
Step-by-step explanation:
Alright, So from the numbers, we know each side is 7
So overall area is 49
And each triangle is 5(5 x 2/2)
And multiply that by 4 to get 20
49 - 20 is 29
Answer: the length of c is √29
Step-by-step explanation:
The Pythagorean Theorem states that "The square on the hypotenuse is equal to the sum of the squares on the opposite sides."
The formula looks like c² = a² + b²
To apply that here, "c" is the hypotenuse of the right triangle that has "2" and "5" as the opposite sides. We can consider 2 as side a, and 5 as side b.
Square each of those numbers, then add them together.
2² means 2×2=4 and 5² is 5×5=25 4+25 = 29
Now we go into reverse to get the value of c. We have c²=29
So we take the square root of 29 c=√29
That is an "irrational" number, meaning it is not a whole number or a fraction. So we can get an approximate value by using a calculator. (Nowadays! Back in the day, there was a nice long paper and pencil procedure. . .)
√29 is about 5.385164807.... and it keeps going. Just round it off!
(Some math teachers are fine with leaving the irrational roots as √something)
Apparently, the green answer box for this question needs √29
But it helps if you can associate some nearly rational value to make sense of it.
But you know the length of c should be about 5.39. It makes sense if you were to measure the sides with a ruler.
Phillp and Arnold are helping their teacher buy supplies for a research project.
The teacher gave Phillip $39.00 to buy pencils from the school store. The pencils come in boxes of 12 and cost $1.95 per box.
Arnold was given $48.00 to buy index cards at an office supply store. Index cards are sold in packs of 200 cards and cost $4.80 per pack.
Each student will receive a bag containing three pencils and 25 index cards. How much will each bag cost?
Part A. Create an equation to model how many boxes of pencils Phillip can purchase. Solve the equation. (5 points)
Part B: How many pencils was Phillip able to purchase? (5 points)
Part C: Create an equation to model how many packs of note cards Arnold can purchase. Solve the equation. (5 points)
Part D: How many note cards was Arnold able to purchase? (5 points)
Part E. In a complete sentence, answer how many bags of 3 pencils and 25 note cards can Arnold and Phillip create (5 points).
Answers
Answer: Part A
20 boxes of pencils
Part B
240 pencils
Part C
10 boxes of note cards
Part D
2,000
Part E
80 bags
Step-by-step explanation:
Part A
Divide 39.00 by 1.95 and you should get your answer
Part B
take the answer you got from part a and multiply it by the number of pencils that are in the box
Part C
take 48.00 and divide it by 4.80 and you should get your answer
Part D
take your answer from Part C and multiply it by how many card are in a box and you should get your answer
Part E
divide the amount of pencils by three and it gives you 80 and for the cards do the same but take the amount of cards and divide it by 25 and it gives you 80 so the amount is 80 bags.
