=> .31x = 21
=> .31x / .31 = 21 / .31
=> x = 67.8 total number of raisins inside the box, or let's convert it to whole number

Earth revolves on its axis once every 24 hours. Which statement are true ? Check all that apply
zhuklara [117]

Answer:

The angular velocity of Earth is π/12 radians per hour.

The angular velocity of Earth is 2π radians per day.

Step-by-step explanation:

A full circumference of a circle (as the Equator line on Earth) is 2π radians.

Since the planet does a full revolution in 24 hours... that means it makes a full turn in a day.

So, we can see that in a day, the planet rotates 360 degrees... or 2π radians per day!

Now, if you want to find the angular velocity per HOUR... you divide that by 24... so  2π/24 = π/12 radians

So, we can also say it does π/12 radians per hour.

salantis [7]

Answer:

C) 6 inches

Step-by-step explanation:

Given function:

Y=1.3x-0.8

The function compares plant height in inches to the age of plant in weeks.

So, we can say

Y represents height of plant in inches.

x represents age of the plant in weeks.

In order to predict the height of the plant in 5 weeks, we will plugin x=5 in the given function and evaluate Y

⇒ Y=1.3(5)-0.8

⇒ Y=6.5-0.8

⇒ Y=5.7 inches

Thus the approximate height of plant in 5 weeks would be \approx 6 inches

The base of an isosceles triangle is one and a half times the length of the other two sides. A smaller triangle has a perimeter
stira [4]

Answer:

P = 1.5x.

Step-by-step explanation:

Let the length of each side of the first triangle be x, then

Perimeter of this triangle

= 2x + 1.5x

= 3.5x.

So perimeter of smaller triangle is:

P = 1/2 * 3.5x

P = 1,.5x.
