The number of applicants to a university last year was 11,450. This year, the number of applicants grew by 2%. How

LenKa [72]

Answer:

The number of students on this year = 11679

Step-by-step explanation:

Number of applicants last year = 11450

The growth on this year = 2 %

So the number of students in this year becomes = 11450 × $\frac{102}{100}$

Thus the number of students = 11679

These are the number of students present on this year.

Find the slope of the line passing through (-7,-8) and (5,-8)

zhenek [66]

Answer:

slope = 0

Step-by-step explanation:

Calculate the slope m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 7, - 8) and (x₂, y₂ ) = (5, - 8)

m = $\frac{-8+8}{5+7}$ = $\frac{0}{12}$ = 0

If you were filling the cylinder up with water using a cone that has the same height and diameter, how many cones will it take t

aleksandrvk [35]

Answer:

It required 3 cones to fill up the cylinder with the same height and diameter.

Step-by-step explanation:

Let the radius of the cone and cylinder be r.

Let the height of the cone and cylinder be h.

As we know that $\text{Volume of cylinder}=\pi r^2h$ ....(1)

$\text{Volume of cone}=\frac{1}{3}\pi r^2h$

It can be observed that the volume of a cone is $\frac{1}{3}$ rd the volume of the cylinder. so, multiply the volume of the cone by 3.

$3 \times \text{Volume of cone}=3 \times \frac{1}{3}\pi r^2h$

$3 \times \text{Volume of cone}= \pi r^2h$

$3 \times \text{Volume of cone}= \text{Volume of cylinder}$ (From equation 1 )

Hence, It required 3 cones to fill up the cylinder with the same height and diameter.

Which of the following is the correct point-slope equation for the line that passes through the point (-6, -1) and is parallel t

inn [45]

Answer:

A. y + 1 = 7(x + 6)

Step-by-step explanation:

1) Point slope form is

y - y1 = m(x - x1)

where m is the slope and (x1, y1) is a point on the line

2) Parallel lines have the same slope

in this case m = 7

-------------------------------

Plug in m = 7 and (x1, y1) = (-6, -1)

y + 1 = 7(x + 6)

which is answer A
