Rewrite the expression with parentheses to equal the given value 100-30÷5 value 14

Answers

Answer 1

Answer:

Answer:

$(100 - 30) / 5$

Step-by-step explanation:

In this question we are given an expression.

We have to put parenthesis() in the expression, to make its value correct.

We follow a BODMAS rule, it states that if there are parenthesis in an expression or given equation, we need to first solve them and then followed by division, multiplication, addition and subtraction.

We are give the expression $100 - 30 / 5$ . We have to add parenthesis such that this expression gives a value of 14.

$(100 - 30) / 5\n= 70 / 5\n= 14$

Thus, the right expression is

$(100 - 30) / 5$

Answer 2

Answer: 5/(100-30)=
5/70=
14. this is the answer

Erin runs laps each day on a track that is 4/8 miles long. This week, she ran 4 4/8 miles on the track. How many laps did she run?

Answers

First, we're going to convert the mixed number into a/n improper fraction.
(4 × 8 ) + 4 = 36/8

Now we're going to divide 36/8 by 4/8 since 4/8 = 1 lap.
36 / 4 = 9.

That is how we get our answer, 9 laps.

Our final answer is 9 laps.

Fifth grade 120 dollars Sixth grade 180 dollars Seventh grade 240 dollars Eighth grade 300 dollars. a.Write three statements that the principal could makewhen comparing the goals each grade has set. b. The teachers set a goal of $225. Write two statements the principal could use to compare this goal to the eighth graders' goal

Answers

The statements that the principal could make when comparing the goals each grade has set are: 7th-grade plan to raise double the 5th grade, 6th-grade plan to raise $(3)/(2)$ 5th grade.6th-grade plan to raise $(2)/(3)$ of 8th grade.

How do we compare numbers?
A comparison statement is, in general, just a statement that compares two quantities or values. For instance, "If we add x apples to 3 apples, then the total number of apples is less than 10 apples" or "Mary's height is the same as Milly's height."

In the given question, we have:

The amount with 5th grade is 120 dollars

The amount with 6th grade is 180 dollars

The amount with 7th grade is 240 dollars

The amount with 8th grade is 300 dollars

So, When we double that with 5th grade will be 240 dollar

Hence, The first statement can be a 7th-grade plan to raise double the 5th-grade.

Similarly,

If we multiply $(3)/(2)$ by the amount of 5th grade, we get 180 dollars.

and, when we multiply two-thirds of the 8th-grade amount, we get 180 dollars.

Hence, The three statements that we can write are:

7th-grade plan to raise double the 5th grade.

6th-grade plan to raise $(3)/(2)$ 5th grade.

6th-grade plan to raise $(2)/(3)$ of 8th grade.

(b)The two statements that could use to compare the goal to 8th graders are:

6th-grade plan to raise $(2)/(3)$ of 8th grade.

8th-grade plan multiplied by $(4)/(5)$ gives 7th grade plan.

When we multiply 300 by $(4)/(5)$ the amount we get 240 dollars.

Hence, The statement that the principal could use to compare the goal to the 8th grader's goal is:

6th-grade plan to raise $(2)/(3)$ of 8th grade.

8th-grade plan multiplied by $(4)/(5)$ gives 7th grade plan.

A cylindrical garbage can has a radius of 2.8ft and holds 86.21 cubic feet of trash. whats the height?A) 3.5ft
B) 9.8ft
C) 5.2ft
D) 1.9ft

Answers

Answer:

Correct choice is A

Step-by-step explanation:

The volume of the cylinder can be calculated using formula

$V=\pi r^2 h,$

where r is the base circle radius and h is the height of the cylinder.

In your case, $V=86.21\ ft^3,\ \ \ r=2.8\ ft,$

then

$86.21=\pi\cdot (2.8)^2\cdot h,\n \nh=(86.21)/(7.84\pi)\approx (86.21)/(7.84\cdot 3.14)\approx 3.5\ ft.$
