Formula for "18 is 32% of what number w?"

I NEED HELPPPPPP It’s about constant rate I DONT GET THIS AT ALL :’( Explanation needed PLEASEEEEEEEE

Vika [28.1K]

Answer:

D Antenna #4

Step-by-step explanation:

As per given graph we can write the function

the intercept is zero, as x=0, y=0

at x=2, y=30 ⇒ 30= 2*15
at x=4, y=60 ⇒ 60= 4*15

The slope is 15, so the function is

y=15x

And the function for the antenna revolving at twice the rate would be

y=30x

Comparing data in given tables we can see it is D Antenna #4

x= 22 ⇒ y= 22*30= 660
x=24 ⇒ y= 24*30= 720

The price of a cup coffee was 2.40 yesterday. Today, the price fell to 2.15 find the percentage decrease. Round the answer to th

irakobra [83]

ANSWER

The percentage decrease is 10.4%.

EXPLANATION

To calculate percentage decrease, use the formula,

Percentage decrease

$= \frac{new \: price - old \: price}{old \: price} \times 100\%$

Yesterday the price of coffee was 2.40. This is the old price.

Today the price is 2.15. This is the new price.

$= \frac{2.15 - 2.40}{2.40} \times 100\%$

$= \frac{ - 0.25}{2.40} \times 100\%$

$= - 0. 10416667 \times 100\%$

$= - 10.416667\%$

To the nearest tenth, we have:

$- 10.4\%$

Therefore the percentage decrease is 10.4%.

What is the height of a rectangular prism that has a volume 192 cubic feet and a base with an area of 48 square feet?

Westkost [7]

Answer:

A rectangular prism has 3 measurements: length (l), width (w), and height (h)

The volume of a rectangular prism has the formula: V=lwh

The area of the base of the rectangular prism is its length times its width; or

Area of base = lw

So, the volume of the rectangular prism can be written as:

Volume = area of the base * height

Substitute in your numbers:

192=48*h

h=192/48

h=4

So the height is 4 feet

Step-by-step explanation: Hope this helps. :))

Gavin likes biking. He never misses a chance to go for a ride when the weather is nice. This week his goal is to bike about 65 t

kvv77 [185]

Answer:

Total Miles he drives first day = 8 miles

Total Miles he drive second day = 12miles

Total Miles he drives third day = 18miles

Total Miles he drives fourth day = 27 miles

Step-by-step explanation:

This is a problem of linear equations in 1 variable:

The linear equations in one variable is an equation which is expressed in the form of ax + b = 0, where a and b are two integers, and x is a variable and has only one solution.

It is given in the question that ,

This week his goal is to drive bike about 65 total miles over four days. Each day, he wants to ride 1.5 times as far as he rode the day before.

Let, on the first day, he drives x miles. On second day, he drives 1.5x. On the third day, he drives 1.5(1.5x) and on the fourth day, he drives 1.5(1.5(1.5x)).

So the equation is :

x +1.5x + 1.5(1.5x) + 1.5(1.5(1.5x)) = 65miles

x + 1.5x + 2.25x + 3.375x = 65miles

8.125x = 65 miles

x = 65/8.125 miles

x = 8 miles

so after solving the equation we get, on the first day Gavin drives 8 miles

similarly, on the second day he drives 12miles

on third day 18 miles

and on the fourth day 27miles
