Phantasy [73]

Given:

$m\angle ABC=60$

To find:

The $m\angle ADC$ .

Solution:

In circle B, $\angle ABC$ is central angle and $\angle ADC$ is inscribed angle from two points A and C.

According to central angle theorem, central angle is always twice of inscribed angle.

$m\angle ABC=2(m\angle ADC)$ [Central angle theorem]

$60=2(m\angle ADC)$

Divide both sides by 2.

$\dfrac{60}{2}=m\angle ADC$

$30=m\angle ADC$

Therefore, $m\angle ADC=30$ .

I have 3 times as much money as my brother. Our total is $24. How much does each of us have?I have 3 times as much money as my b

musickatia [10]

Answer:

Brother's money = $6

Money I have = $18

Step-by-step explanation:

Hi, to answer this question we have to write an equation with the information given:

<em>I have 3 times as much money as my brother: </em>

Money I have = 3x

Where x is the money that my brother has:

Brother's money = x

<em>Our total is $24 </em>

So, 3x+x =24

Solving for x

3x+x=24

4x =24

x =24/4

x = 6

Replacing with the value of x.

Brother’s money = x = $6

Money i have = 3x =3(6) = $18

write an equation to represent the relationship, and find the amount of peanut butter used to make 25 cracker packages. the tabl

Nadusha1986 [10]

We are given 4 points.

$(\frac{1}{2},2)$

$(\frac{5}{8},\frac{5}{2})$

$(\frac{3}{4},3)$

$(\frac{7}{8},\frac{7}{2})$

Using this, we can make an equation.

$y=4x$

I got $m=4$ by using the slope formula.

$m=\frac{2.5-2}{0.625-0.5}$

$m=\frac{0.5}{0.125}$

$m=4$

So the equation we have is $y=4x$

Now, we can solve for how much peanut butter is used to make 25 packages by plugging in 25 for $y$ , which is the number of cracker packages.

$25=4x$

$x=\frac{25}{4}$

We need to use $\frac{25}{4}$ teaspoons of peanut butter to make 25 packages of crackers.

Hope this helps.

頑張って!

Answer with explanation:

$\text{Average}=\frac{\text{Sum of all the observation}}{\text{Total number of Observation}}$

Average Height of tallest Building in San Francisco

$=\frac{260+237+212+197+184+183+183+175+174+173}{10}\\\\=\frac{1978}{10}\\\\=197.8$

Average Height of tallest Building in Los Angeles

$=\frac{310+262+229+228+224+221+220+219+213+213}{10}\\\\=\frac{2339}{10}\\\\=233.9$

→→Difference between Height of tallest Building in Los Angeles and Height of tallest Building in San Francisco

=233.9-197.8

=36.1

⇒The average height of the 10 tallest buildings in Los Angeles is 36.1 more than the average height of the tallest buildings in San Francisco.

⇒Part B

Mean absolute deviation for the 10 tallest buildings in San Francisco

|260-197.8|=62.2

|237-197.8|=39.2

|212-197.8|=14.2

|197 -197.8|= 0.8

|184 -197.8|=13.8

|183-197.8|=14.8

|183-197.8|= 14.8

|175-197.8|=22.8

|174-197.8|=23.8

|173 -197.8|=24.8

Average of these numbers

$=\frac{62.2+39.2+14.2+0.8+13.8+14.8+14.8+22.8+23.8+24.8}{10}\\\\=\frac{231.2}{10}\\\\=23.12$

Mean absolute deviation=23.12
