Joylin’s work to solve a math problem is shown below.

Problem: Manny walked StartFraction 5 Over 16 EndFraction of the distance to the library in One-third of an hour. If he walks at a constant rate, what is the total amount of time he will spend walking to the library?

Step 1:
StartFraction 5 Over 16 EndFraction divided by one-third = h
Step 2:
StartFraction 16 Over 5 EndFraction times StartFraction 3 Over 1 EndFraction = h
Step 3:
StartFraction 48 Over 5 EndFraction = h
Answer:
9 and three-fifths = h

What was Joylin’s first error?
She switched the divisor and the dividend when creating an equation to model the problem in step 1.
She replaced both the divisor and the dividend with their reciprocals when changing division to multiplication in step 2.
She multiplied the two numerators and the two denominators to generate her product in step 3.
She reduced the improper fraction incorrectly when getting her final answer.

Step-by-step explanation:

the answer is 50 because 2x-=76 is k :)

Answer:

k (oats in cups) = 25 (grams of almonds)

Step-by-step explanation:

If you look at the coordinates given in the question (1,k) where we are told to find k.

A coordinate is a pair of one x and y value, an input and output in a relationship.

2d coordinates are in the form of (x,y), this means that (1,k) is representing what k will be when x is 1. So to find k, we must look at where y (the amount of almonds in this instance) is when x (the oats) is 1.

This graph looks to be y = 25x.

Where y is the oats in cups, and x is the grams of almonds. This is a proportion which means that there are 25 grams of almonds for every 1 cup of oats.

Answer:

7/8

Step-by-step explanation:

well first when you put them together like 3/8 and 7/9 you have to simplfy first. You have to cross simplify 3 and 3. Since they are the saem both turn into one. Now you mulitpy. 7 times 1 is 7 and 8 times one is 8. 7/8

Answer:

[tex]\frac{7}{24}[/tex]

Step-by-step explanation:

To factor an integer, we need to repeatedly divide it by the ascending sequence of primes (2, 3, 5...).

The number of times that each prime divides the original integer becomes its exponent in the final result.   In our example,  Prime number [tex]2^3=8[/tex]

[tex]\frac{3*7}{2^3*3^2}[/tex]

We need to perform a multiplication. The following rule is applied:

[tex]\frac{A}{B}*\frac{C}{D}=\frac{AC}{BD}[/tex]

In our example, the factors in the new numerator are 3,7

The factors in the new denominator are [tex]2^3, 3^2[/tex]

Answer:

how many trucks ?

Step-by-step explanation:

It is solved using the rule of three simple ones, where the number of trucks is for the quantity of material transported. We have that 1 is for 8 as X is for 104 (Look attached).

Multiplying cross, we have to:

8X = 104

X = 104/8

X= 13

96.666..., or about 97 minutes/every mile.

Step-by-step explanation:

Answer:

340 total people (see below)

Step-by-step explanation:

So first, you need to find the number of children. To do that, the percentage of adults must be 55% because is 45% of 100% are children, the remaining are adults. You can use a ratio to find the amount of children:

x children  =  45%

187 adults     55%

Now, cross multiply:

55x = 187 (45)

55x = 8415

x = 8415/55

x = 153

There are 153 children.

To find the total amount of people in the theater, add the two amounts:

187 adults + 153 children = ? people

                                           = 340 people

Answer: -2

Step-by-step explanation:

Slope=rise/run

In this case we rise up 4

And we run 2 to the left which makes it a negative

So in this case the slope is -4/2

Which can be simplified to -2

Answer:

$24

Step-by-step explanation:

James

Allowance per week = $6

He spends = $4

Balance = $6 - $4 = $2

Mike

Allowance per week = $7

He spends = $3

Balance = $7 - $3 = $4

Their mother's birthday is in 4 weeks

how much money can they save together in that time to buy her present?

James savings per week × 4 weeks

= $2 × 4

= $8

Mike's savings per week × 4 weeks

= $4 × 4

= $16

Total amount James and Mike can save together = $8 + $16

= $24

Answer:

468

Step-by-step explanation:

and this is how you spell answers

The value of 78 × 6 is 468

Multiplication is the process of calculating the product of two or more numbers. The result of multiplication is called product.

If a × b = c , this means that a and b are the factors and c is the product.

For example if each student has 5 apples and there are 100 students in the camp, the total number of apples in the camp is

100 × 5 = 500 mangoes.

Similarly, 78 × 6

= 70 × 6 + 8 × 6

= 420 + 48

= 468

Therefore the product of 78 and 6 is 468

Given:

Volume of a cubed room = 8000 cubic ft

Cost of floor hardwood = $10 per square foot

To find:

The total cost of floor hardwood.

Solution:

Let the each side of cubed room be x ft.

Volume of a cube is cube of its side.

Volume of a cubed room is 8000 cubic ft. So,

[tex]x^3=8000[/tex]

Taking cube root on both sides.

[tex]x=20[/tex]

So, length of each of room is 20 ft.

Area of base = length × breadth

So, area of base of room is

[tex]20\times 20=400\text{ ft}^2[/tex]

It means, 400 sq ft  hardwood is required for the floor.

Cost of floor hardwood is $10 per square foot. So, total cost of hardwood floor is

[tex]400\times 10=4000[/tex]

The hardwood floors will cost ​$4000.

Step-by-step explanation:

ATQ,

Let d be the number of kilograms of dark chocolate she buys and m be the number of kilograms of milk chocolate she buys.

She needs to buy 120 kg of chocolate in total for her next order, and her recipe calls for twice the amount of dark chocolate as milk chocolate.

So,

m = 2d .....(1)

m + d = 120 ...(2)

We can also solve the above equations,

Put m = 2d in equation (2)

2d + d = 120

3d=120

d = 40

Put d = 40 in equation (1)

m = 2(40)

m = 80

Hence, she will need 40 kg of dark chocolate and 80 kg of milk chocolate.

Answer:

d+m=120

d=2m
