The angles of a triangle are 99°, 3x°, and x + 5°. What is the value of x?

Sum of all angles in a triangle is 180°

99 + 3x + x + 5 = 180 | Sum of all the 3 angles = 180

4x + 104 = 180 | Combine like terms

4x = 76 | take away 104 from both sides

x = 19° | Divide by 4 on both sides

Answer: x = 19°

99 + 3x + x + 5 = 180 | Sum of all the 3 angles = 180

4x + 104 = 180 | Combine like terms

4x = 76 | take away 104 from both sides

x = 19° | Divide by 4 on both sides

Answer: x = 19°

X = 19 degrees.

Alex buys 2 1/2 pounds of grapes. He buys 1 1/4 times as many pounds of apples as grapes. How many pounds of apples does he buy?

So if, 2 1/2 = 5/2 and 1 1/4 = 5/4,

then 5/2 * 5/4 = 5*5 / 2*4 = 25/8 is simplified to 3 1/8 pounds.

then 5/2 * 5/4 = 5*5 / 2*4 = 25/8 is simplified to 3 1/8 pounds.

Grapes = 2 1/2 pounds = 5/2 pounds

Apples = 1 1/4 times grapes = 5/4 times grapes

Apples = 5/4 * 5/2 = 25/8 pounds = 3 1/8 pounds

Apples = 1 1/4 times grapes = 5/4 times grapes

Apples = 5/4 * 5/2 = 25/8 pounds = 3 1/8 pounds

If a certain cannon is fired from a height of 9.4 meters above the ground, at a certain angle, the height of the cannonball above the ground, h, in meters, at time, t, in seconds, is found by the function h(t)=-4.9t^2+30.5t+9.4. Find the time it takes for the cannonball to strike the ground.

Answer:

6.5 s

Step-by-step explanation:

The equation provided provides us with the height of the canonball at any time t. When the ball hits the ground, the height of the ball above the ground is zero.

Therefore

h(t)=-4.9t^2+30.5t+9.4 = 0

We then solve for t. Seeing as this is a quadratic equation, we can use the quadratic formula:

The quadratic formula gives two answers, a positive one and a negative one. The positive one is after time zero and the negative one is before time zero. We are interested in the one after time zero (time zero being the time when the canon is fired)

Find the mean 10,12,17,14,20,27,24,28,28

Hi Kimberlys969pdrfzz,

Question:

Find the mean

Mean - "The mean is the average of the numbers: a calculated "central" value of a set of numbers. To calculate it: add up all the numbers, then divide by how many numbers there are."

Solution:

Answer:

Mean = 20

Hope This Helps!

10 + 12 + 17 + 14 + 20 + 27 + 24 + 28 + 28 = 180/9 = 20

mean: 20
