Answer:

Answer with explanation:

Perimeter of watermelon field yard

1 yard =3 feet

So, perimeter

feet

Width of Watermelon field = 44 feet

Kaisa , plants watermelon in the field in rows which are feet apart.

Number of watermelon planted in a single row =x

Let , Length of Watermelon field

Perimeter of field = 2 *[Length +Breadth]

Number of watermelon in a row =24(approx)

Length of watermelon field

feet

Let number of rows of watermelon = y

= 2 Rows(approximately)

Answer: She should be able to plant about 4 rows

What’s the missing value in the solution to the equation of y+2=-3(x-4) If y =-2

Answer:

-2+2=-3(x-4)

0=-3x+12

-12=-3x

4=x

pam uses 1 half cup of milk for each milkshake if she makes 18 milk shakes how many cups of milk does she use

I am not going to give you the answer, but I am going to tell you how to do it. You first put 18 over 1, and multiply that by one half. (You multiply across.)

When two six-sided dice are rolled, Find the probability that the sum is not 4.

Short Answer: 11/12

Step One

How many ways can you throw two dice?

There are 6 faces on a cube. Each cube has a different number. (Opposite sides add up to 7 -- that last fact is not important, but it is interesting).

So the total number of ways you can throw 2 dice is 6 * 6 = 36

Step Two

How many of those 36 will give you 4? To make the problem slightly easier to understand, make 1 dice red, and 1 blue and just list the ways.

Red Blue

1 3

3 1

2 2

That's Three ways that you can throw a four

Step Three

What's the probability of throwing a 4?

3 successful ways 36 total ways.

3 / 36 = 1 / 12

Step Four

What is the probability of not throwing a 4?

1 - P(4) = 1 - 1/12 = 11/12

By proportion

9/7 = 72/x where x = amount of flour

x = (7*72) / 9

= 7*8

= 56 ounces.

What is the result when the number 17 is increased by 7.3%

Answer: 18.241

Step-by-step explanation:you have to take 17 times .073. Which is 1.241. Then add that to 17

HIGH SCHOOL

What percent of 77 is 7?

So what ya do is multiply 77% and 7 to get 5.36.

**Note: when you see the word of in a percent problem then it prob. means that you are going to multiply.*

**Note: when you see the word of in a percent problem then it prob. means that you are going to multiply.*

You take .77 and multiply it by 7 to get 5.39

A timber fence is to be built on sloping land, with the shortest piece of timber 1.2m and the longest 1.8m. there are 61 pieces of timber in the fence. b) what length of timber is needed for the fence altogether?

Tn=a+(n-1)d

1.8=1.2+60d

d=.001m=1mm

this is d difference in length

sum=n/2(a+tn)

=61/2*3

=91.5m

1.8=1.2+60d

d=.001m=1mm

this is d difference in length

sum=n/2(a+tn)

=61/2*3

=91.5m

What number is represented by a point 6 units to the left of -5 on the number line shown?

Answer:

The number is -11

Step-by-step explanation:

So let us stand at -5 on the number line.

We then move 6 units to the left.

This will give us the expression

We simplify this to get:

Therefore the new point will be at -11
