Maya has 54 cubic feet in her garden she already has 4.5 cublc feet of soil .Soil bags have 1.5 how many bags should maya purchace.

Answers

Answer: 33

Step-by-step explanation:

The cubic feet needed is 54 and she already has 4.5 cubic feet of soil. This mean that she will need 49.5 more.

= 54 - 4.5

= 49.5

Since each soil bag has 1.5, the number of soil bags needed will be:

= 49.5 / 1.5.

= 33

Therefore, she'll need 33 bags

The first snack is 270 calories for 3 servings, and the second snack is 450 calories How many servings does the snack have to have in order to equivalent to the first snack?

Answers

Answer:

5 servings

Step-by-step explanation:

Given that:

For a particular first snack  to be = 270 calories;

the servings = 3

Then, for the second snack, the calories = 450.

To estimate the servings for the second snack; we need to equate the first snack with the second snack.

Let y be the value of the unknown second snack

Then:

270 calories = 3 servings

450 calories = y servings

y servings = (450 calories × 3 servings) / 270 calories

y servings = 5 servings

Thus; the second snack needs to have 5 servings in order to be equivalent to the first snack

what is the solution set of this inequality x < -10 i need help

Answers

Answer:

x= 1 (any number greater than -10)

Step-by-step explanation:

">" this sign shows that any number greater than -10 can be x. There is no specific answer.

Answer:

The solution set of an inequality is < (less than) or > (greater than) to compare two or more numbers. Example 12 > - 10.

Step-by-step explanation:

When comparing two numbers, like 5 and 8, you probably recognize that the number 5 is less than the number 8. You probably also realize that the number 8 is greater than the number 5. In math, we use the inequality symbols < and > to compare two or more numbers.

There were 220 people who voted at the 6th grade meeting. Sixty percent of the voters are in favor of changing the school mascot. How many people are against changing the mascot? Use numbers and words to explain your answer.

Answers

Step-by-step explanation:

First I had to find 60% of 220.

220 × .60 = 132.

132 people are in favor so I have to subtract that number from 220 to find how many people were against.

220-132 = 88

88 people were against changing the mascot.

[tex]P(Hits) = 0.70[/tex]

Step-by-step explanation:

Given

[tex]Throws = 120[/tex]

[tex]Hits = 84[/tex]

[tex]Miss = 36[/tex]

See attachment for result

Required

Determine the probability of hitting the target

This calculated using:

[tex]P(Hits) = \frac{n(Hits)}{n(Throws)}\\[/tex]

[tex]P(Hits) = \frac{84}{120}[/tex]

[tex]P(Hits) = 0.70[/tex]

Hence, the probability of hitting the target is 0.70

The sum of two numbers is 46 and their
difference is 20. What is the smaller
number?

A) 40
B) 13

D) 12

Answers

46/2 is 23
20/2 is 10
The number is + or - 23
So 13 and 33
13

Answer:

B. 13

Step-by-step explanation:

We have two unknown numbers, let's have two variables for these two unknown numbers, X and Y.

"The sum of two numbers is 46 and their difference is 20."

Meaning we have two equations :

X + Y = 46

X - Y = 20

Looking at the last part of "their difference is 20." We can assume X = Y + 20

So substitute the assumed equation into X + Y = 46

(Y + 20) + Y = 46

2y + 20 = 46

Subtract 20 from both sides :

2y = 26

Divide 2 by both sides :

y = 13

There you go.
