Can you help me find the measure of each angle? Diagram attached

never [62]

<u>Answer:</u>

5x = 100°

4x = 80°

<u>Step-by-step explanation:</u>

We are given a diagram with a straight line AC being intersected by another line BD and we are to find the two mentioned angles.

We know that the two angles (5x° and 4x°) are supplementary so their sum would be equal to 180°.

So we can write it as:

$5x+4x=180$

$9x=180$

$x=\frac{180}{90}$

$x=20$

Finding the measure of both the angles:

$5x = 5(20) =$ 100°

$4x = 4(20) =$ 80°

The function f(t) represents the cost to connect to the Internet at an online gaming store. It is a function of t, the time

EleoNora [17]

The true statement about the Internet connection cost is D. Any amount of time over an hour and a half would cost $10.

<h3>How to explain the cost?</h3>

In this situation, the function is f (t), when t is a value between 0 and 30. The cost is $0 for the first 30 minutes

When t is a value between 30 and 90, the cost is US$ 5 if the connection takes between 30 and 90 minutes.

Here, the true statement about the Internet connection cost is D. Any amount of time over an hour and a half would cost $10.

The average weight of full-grown beef cows is 1,470 pounds with a standard deviation of 230 pounds. if the weights are normally

creativ13 [48]

Answer: The percentile is 89

Step-by-step explanation:

This question can be solved using concept for t tables

In a normal distribution the curve. $\mu= 1470 , \sigma = 230, x=1750$

The relationship between z score, mean and standard deviation is given by

$x = \mu+z\sigma$

So the z value according to this is given by the formula

$1750=1470+z(230)\\ z=\frac{280}{230} \\\\z = 1.217$

From the z table we can infer that p value for z=+1.217 is 88.82

So 1750 is 89th percentile
