If 40% of the students in the class are boys, and if there are 15 girls in the class, then how many students are in the class? * 1 point

Answers

Answer 1

Answer:

25

Step-by-step explanation:

15/6.0=2.5

2.5x4=10

2.5x6=15

10+15=25

10 boys and 15 girls

Answer 2

Answer:

25

Step-by-step explanation:

Let's set up "x" as the total number of students. So now we can set up an equation:

40%x+15=x rewritten as:

.4x+15=x Subtract .4x from both sides will give us:

 

15=.6x Now divide each side by .6 to be:

25=x Therefore we know there are 25 students in the class.

Make sense?

Roger jarred 15 liters of jam after 2 days. How much jam did Roger jar if he spent 6 days making jam?​

Answers

Answer: 45 liters

Step-by-step explanation:

If Roger jars 15 liters of jam in 2 days, we can divide to see how much liters of jam Roger can jar in 1 day. We can divide 15 by 2 to find how much jam can be jarred in one day.

15 / 2 = 7.5.

Roger can jar 7.5 liters of jam every day.

Now we can multiply 7.5 by 6 to find how much jam Roger can jar at the end of 6 days.

7.5 x 6 = 45.

Therefore, Roger can jar 45 liters of jam in 6 days.

What is the volume of a cube with an edge length
of 2/3 foot?

Answers

Answer:

V= 512 inches or, 42.67 feet

Step-by-step explanation:

So a cube has the same length on all sides so you would multiply length times with times area or V = a^3

So, 2/3 foot is equal to 8 inches so you would do V = 8^3 which would get you the answer,

The length of a rectangle is 16 units more than its width. The area of the rectangle can be expressed as
x^4 – 64.
Which expression represents the width of the rectangle?

Hiiii your answer is (x2+8)(x2-8)

The width of the rectangle represented by the expression (x⁴ – 64)/x.

What is rectangular shape?

A quadrilateral with parallel sides that are equal to one another and four equal vertices is known as a rectangle.

Given:

The length of a rectangle is 16 units more than its width.

Let the length is x units.

Then width = (x + 16) units.

The area of the rectangle can be expressed as

x⁴ – 64 = length x width

x⁴ – 64 = x (x + 16)

x + 16 =(x⁴ – 64)/x

Therefore, the width expression is (x⁴ – 64)/x.

The Patel family looks at map to plan their family vacation. They plan to travel from Smithville to Jonesville, which are 3 3/4 inches apart on the map. Then they plan to travel from Jonesville to Clarksville, which are 5 1/4 inches apart on the map. The scale on the map is 1/2 inch equals 4 miles. What is the actual distance the Patel family will travel by the time they reach Clarksville? Enter your answer in the box

Answers

Answer: 72 miles

Step-by-step explanation:

The total distance from Smithville to Clarksville will be:

= 3 3/4 + 5 1/4

= 9 inches

Since the scale on the map is:

1/2 inch = 4 miles

1 inch = 4 × 2 = 8 miles

Therefore, 9 inches will be:

= 9 × 8 = 72 miles

The actual distance that the Patel family will travel by the time they reach Clarksville will be 72 miles.
