What number makes the fractions equivalent?

Answer:

The length is 6 ft

Step-by-step explanation:

The area of a square is given by

A = s^2 where s is the side length

36 = s^2

Take the square root of each side

sqrt(36) = sqrt(s^2)

6 =s

The length is 6 ft

Answer:

6 ft

Step-by-step explanation:

We know that the formula to find the area of a square is :

Area = a² ( length × width)

According to the question they've already given the area of the square as 36ft².

So, to find the the measure of a one side, let the in unknown measure of a side be a.

And now, using the formula let us find the value of a ( length of a one side).

[tex] \sf \: Area = a² \\ \sf 36 = a² \\ \sf \: \sqrt{36} = a \\ \sf6ft = a[/tex]

Mean time = 142 minutes

One of the the most common expression for the mean of a statistical distribution with random variables is the average of all the terms. The mean of  any given data can be found out by adding all numbers in the data set and then dividing that by the number of values.

First calculate the mid point of the time interval :

(15+17)/2=16

(17+19)/2 = 18

(19+21)/2= 20

(21+23)/2= 22

Multiply each time mid point with respective frequency :

16*5=80

18*12= 216

20*7= 140

22*6= 132

Adding this and dividing by the total number of times that is 4:

= (80+216+140+132)/4

= 568/4

Mean time =142 minutes

Answer:

she cannot go on the field trip.

Step-by-step explanation:

Day 1 = 5, done = 3, remaining = 2.

Day 2 = 2 + 5, done = 6, remaining = 1

Day 3 = 1 + 5, done = 2, remaining = 4

Day 4 = 4 + 5, done = 4, remaining = 5

Day 5 = 5 + 5, done = 3, remaining  = 2 + 5

Day 6 = 2 + 5 + 5, done = 7, remaining = 5

Day 7 = 5 + 5, done = 1, remaining = 4 + 5

Day 8 = 4 + 5 + 5, done = 3, remaining = 1 + 5 + 5

Day 9 = 1+ 5+ 5+ 5, done = 2, remaining = 4+5+5

Day 10 = 4+5+5+5, done = 10(maximum assignment done assumed), remaining = 4 + 5

At the end of day 10, she had 9 remaining assignments, so she cannot go on the field trip.

Using percentage we can calculate that 81 students did not take French.

In mathematics, a number or ratio that is expressed as a fraction of 100 is referred to as a percentage. Although the abbreviations "pct" and "pc" are also often used, the percent symbol "%" is the one that is most frequently used. A % is a number that has neither established units of measurement nor dimensions.

The percentage can be calculated by taking the value and dividing it by the total value, then multiplying the result by 100. using the formula (Value/Total Value) × 100% to calculate percentages.

Let the total number of students be x.

Now 91% of this students is equal to 819.

Now using the properties of percentages we can write:

91% of x = 819

or, x = 900

Number of students who did not take French = 900 - 819 = 81

Hence using percentages we can say that 9% or 81 students did not take French.

The value of the distance LM in which M is the midpoint between L and N is 64 units.

What is midpoint?

In mathematics. the term midpoint states the middle line of the line segment joining the two sides of the triangle make the third side parallel to the line segment and it also bisect the third side.

According to the question, the point M is the midpoint between L and N. The given parameters are: LM = 12x-8; MN = 14; and LN = 6x + 30

Using standard midpoint property, the distance LN can be written as:

LN = LM + MN ⇒ 6x + 30 = 12x-8 + 14

Taking variables terms one side, we get

6x = 36 ⇒ x = 6

Therefore,

LM = 12x-8 ⇒ 12(6) - 8 = 72 - 8 = 64

In order to determine the time or times for this ball at a height of 34 feet, we would simply substitute the value of the height into the function h(t) as follows;

h(t) = -16t² + 80t + 5

34 = -16t² + 80t + 5

Re-arranging the equation, we have:

16t² - 80t + 34 - 5 = 0

16t² - 80t + 29 = 0

Next, we would solve the quadratic equation by using the quadratic formula:
