For a cone, if the radius was quadrupled and the slant height was reduced to 1/6 of its original size what would be the formula to find the modified surface area.

Answers

Let r be the radius of the cone's base and \ell the slant height.

The surface area of a cone is

A=\pi r^2+\pi r\ell

If the radius is quadrupled (r\to4r) and the slant height scaled by a factor of \frac16, then the new area is

A=\pi(4r)^2+\pi (4r)\left(\frac\ell6\right)
A=16\pi r^2+\frac23\pi r\ell

after elsa baked muffins, her brother ate 4 of them. he ate 2 5 of all of the muffins. how many muffins did elsa bake?

Answers

If you would like to know how many muffins did Elsa bake, you can calculate this using the following steps:

2/5 of all of the muffins = 4 muffins
2/5 * x muffins = 4
2/5 * x = 4        /*(5/2)
x = 4 * 5/2
x = 10 muffins

The correct result would be 10 muffins.

A painter built a ladder using 18 rungs. The rungs on the ladder were 5.7 inches apart and 1.1 inches thick. What is the distance from the bottom of the lowest rung to the top of the highest rung?

Answers

The distance from the bottom of the lowest rung to the top of the highest rung 116.7 inch

What is Unitary method?

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given:

Total rungs = 18

distance between rungs = 5.7 inch

thickness = 1.1 inches

So, the distance from the the lowest rung to top of highest rung is

=18* 5.7 + 17* 1.1

=116.7 inch

Bradley is in a class of 15 boys and 10 girls. 40% of the class takes the bus to school. How many students do not take the bus to school?

Answers

Answer:

30 Students

Step-by-step explanation:

As given

Bill is in a class of 15 boys and 35 girls.

Total number of students in the class = Number of boys + Number of girls

                                                             = 15 + 35

                                                             = 50

As given

40% of the students in the class take the bus to school.

40% is written in the decimal form.

= 0.40

Number of students take bus to school = 0.40 × Total students in class.

                                                                 = 0.40 × 50

                                                                 =  20

.Thus

Students not take bus to school = Total students - Number of students take bus to school

                                                     = 50 - 20

                                                     =  30

Therefore 30 students not take bus to school .

Answer:

15 students

Step-by-step explanation:

First of we have to calculate how many students there are in the class. There are 15 boys and 10 girls, whish means there are 25 people in total (15+10=25).

Since 40% takes the bus to school, 60% of the sudents do not take the bus to school. The easiest way to calculate how many students is 60% is to first divide the students with 10. 25/10 is 2.5. 2.5 students is 10% of 25 students (100% divided by 10 is 10%).

To get 60%, the number of students has to be multiplied with 6, because 10% times 6 is 60%.

2.5 (10%) times 6 is 15, so the answer is 15.
