Cups by the water cooler are in the shape of a cone. The height is 15 cm and the diameter is 7.6 cm.

What is the volume of one water cooler cup, in cubic centimeters? (Use 3.14 for
π.)

Answers

Answer 1

Answer:

226.7 cm³

Step-by-step explanation:

The cone volume formula is V = (1/3)(base area)(height).

Here that comes out to V = (1/3)(pi)(3.8 cm)^2·15 cm, or 226.7 cm³

Write an equation for this graph

Answers

Answer:

y = 3x

Step-by-step explanation:

m = (6-3)/(2-1) = 3/1 = 3

Answer: y=3x

Step-by-step explanation:

To write an equation, the first step is to look at the rise/run. In this graph, the rise is 3 and the run is 1. 3 divided by 1 is still 3 so in the equation mx+b, the m, also known as the slope, would be 3.

3x+b

And the b is the y-intercept where the line crosses the y axis.

3x+0=y

Therefore;

3x=y

HOPE THIS HELPED!!!

Answer:

[tex]\huge\boxed{\boxed{12a-60}}[/tex]

Step-by-step explanation:

Hello.

The Distributive Property states that

a(b+c)=ab+ac

Where

a, b, and c can be either constants or variables

we distribute a by multiplying it times b and c, and simplify if necessary.

In this case, we should distribute 12:

12(a-5)

12 times a and 12 times (-5):

12a-60

And we're done!

I hope it helps & have an outstanding day!

At the start of a hike, a hiker was at an elevation of -50 feet (where 0 represents sea level). The hiker climbs at a rate of 15 feet per minute. a. Write an inequality that represents t, the number of minutes after the start of the hike, when the hiker’s elevation was higher than 5 feet above sea level.

Answers

Answer:

15t - 50 > 5

Step-by-step explanation:

Initial point = -50 ftClimbing rate = 15 ft / minTime = t

Required inequality:

15t - 50 > 5

Solution:

15t > 55t > 55/15t > 3 10/15 = 3 40/60 min = 3 min 40 seconds

Answer:

Solution given:

Initial point = -50 ft

Climbing rate = 15 ft/min

Time = t(let)

So Required inequality:

15t-50 > 5

adding 50 on both term

15t> 55

dividing both term by 15

t > 55/15

t> [tex] 3 \times \frac{10}{15} [/tex]=

Mold B

Mold C

Mold D

Answers

Answer:

mold B

Step-by-step explanation:

The molds are of cylindrical shape. The volume of a cylinder is given by:

Volume = πr²h

where r is the radius and h is the height.

For mold A: diameter = 2 inches, hence radius = 1 inch. Height = 7 inches

volume = π(1²)7 = 7π in³

For mold B: diameter = 2 inches, hence radius = 1 inch. Height = 4 inches

volume = π(1²)4 = 4π in³

For mold C: diameter = 3 inches, hence radius = 1.5 inch. Height = 3 inches

volume = π(1.5²)3 = 6.75π in³

For mold C: diameter = 4 inches, hence radius = 1.5 inch. Height = 3 inches

volume = π(2²)3 = 12π in³

Therefore mold B has the smallest volume

The Monday after Thanksgiving is called Cyber Monday. Amazon is
offering deals on many popular items. The same drone helicopter
is normally sold for $179.99, but on Cyber Monday, Amazon will be
selling it for $125.99. What is the percent change on the drone. Round to the nearest percent

Answers

Answer:

the percentage change on the drone is 42.86%

Step-by-step explanation:

The computation of the percentage change is shown below:

Since the helicopter was sold for $179.99

But amazon would be selling it for $125.99

So, the percentage change would be

= (Sale value -  sale value by amazon) ÷ ( sale value by amazon) × 100

= ($179.99 - $125.99) ÷ ($125.99) × 100

= 42.86%

Hence, the percentage change on the drone is 42.86%
