in this picture lines AB and CD are parallel. Find the measures of the following angles. Explain your reasoning.

Answer:

The PLATO answer...

Answer:

See below

Step-by-step explanation:

[tex]2(x+5)-3 =15[/tex]

Using the distributive property in the LHS we get

[tex]2x+10-3 =15[/tex]

[tex]2x+7=15[/tex]

Now add -7 both sides. So we have the subtraction property of equality.

[tex]2x+7+(-7)=15+(-7) \text{ This is what I meant for add}[/tex]  

[tex]2x+7-7=15-7[/tex]

[tex]2x=8[/tex]

Now divide both sides by 2. So we have the division property of equality

[tex]\dfrac{2x}{2} =\dfrac{8}{2}[/tex]

[tex]x=4[/tex]

Answer:

Amount made from selling pool rafts on Friday is equal to $108.02

Step-by-step explanation:

Total amount made from selling pool rafts = $564

Amount made from selling pool rafts on Monday = $132.56

Amount made from selling pool rafts on Tuesday = $107.38

Let amount made on each of the days - Wednesday, Thursday, and Friday be equal to $x.

Therefore,

[tex]132.56+107.38+x+x+x=564\\239.94+3x=564\\3x=564-239.94\\3x=324.06\\x=\frac{324.06}{3}\\ x=$108.02[/tex]

So,

amount made from selling pool rafts on Friday is equal to $108.02

Answer:

$1,126.37

Step-by-step Explanation:

Given:

Account balance for:

Month 1 = $1285.12

Month 2 = $961.36

Month 3 = $1132.63

Required:

Average balance of account

SOLUTION:

Average balance of account = sum of account balance for the 3 months ÷ 3

Average balance of account = [tex] \frac{1285.12 + 961.36 + 1132.63}{3} [/tex]

Average balance of account = [tex] \frac{3,379.11}{3} [/tex]

Average balance of account = [tex] 1,126.37 [/tex]

Answer:

$1,126.37

Answer:

The submarine is at -1260 ft.

It descends 5 ft/min for 12 min.

12 min * 5 ft/min = 60 ft.

It descended 60 ft, so you must subtract 60 ft from -1260 ft.

-1260 ft + (-5)(12) ft = -1260 ft - 60 ft = -1320 ft

The error in the last line in the problem is that (-5)(12) = -60, not 60.

The correct line is:

-1260 + (-5)(12) = -1260 - 60 = -1320

Step-by-step explanation:

Answer:

The correct answer is: A

Step-by-step explanation:

The value of the slope and intercept is:

=0.92(42268/27569)

=1.410518

a=y-bx

=634235-1.410518×326845

=173214.3716

The eququation for the least-square regression line is:

y=173214.3716 + 1.4105518x

Round to the 2 decimal place:

=173,214.37 +1.41x

The equation for the least squares regression line for number of property crimes compared with number of battery crimes is (b) y = 141x + 173214.37

The given parameters are:

Calculate the slope (m) using:

m = r * Sy/Sx

This gives

m = 0.92 * 42268/27569

Evaluate

m =1.41051761036

Approximate

m = 1.41

The y-intercept (c) is calculated using:

c = μy -m * μx

So, we have:

c = 634235 - 1.41051761036 * 326845

Evaluate

c = 173214.371642

Approximate

c =173214.37

The least-square regression line equation is represented as:

y = mx + c

So, we have:

y = 141x + 173214.37

Hence, the equation for the least squares regression line for number of property crimes compared with number of battery crimes is (b) y = 141x + 173214.37

Answer: D. 50 students

pls give me brainliest.

Step-by-step explanation: First we find the area of the classroom which is worked out below and it is the shape of a rectangle;

Area of a rectangle = Length * Breadth

                               = 60 ft * 40 ft

                               = 2400 ft²

Now to find the number of students that she will allow in the classroom, we have to divide the area of the classroom which is 2400 ft²by the amount of space allocated to each student which will be;

=

= 50

This means she will  allow 50 students into her class.

[tex]Probability = \frac{7}{253}[/tex]

Step-by-step explanation:

Given

[tex]Orange = 7[/tex]

[tex]Green = 6[/tex]

[tex]White = 1[/tex]

[tex]Black = 7[/tex]

[tex]Yellow = 2[/tex]

Required

Probability of selecting a yellow then orange rock

From the question, we understand that the probability is that of without replacement.

Since the yellow, is first picked.

We need to determine the probability of picking a yellow rock, first.

[tex]P(Yellow) = \frac{n(Yellow)}{Total}[/tex]

[tex]P(Yellow) = \frac{2}{7 + 6 + 1 + 7 + 2}[/tex]

[tex]P(Yellow) = \frac{2}{23}[/tex]

The rock has reduced by 1;

Next is to determine the probability of picking an orange rock

[tex]P(Orange) = \frac{n(Orange)}{Total - 1}[/tex]

[tex]P(Orange) = \frac{7}{7 + 6 + 1 + 7 + 2- 1}[/tex]

[tex]P(Orange) = \frac{7}{22}[/tex]

The required probability is calculated as thus:

[tex]Probability = P(Yellow) * P(Orange)[/tex]

[tex]Probability = \frac{2}{23} * \frac{7}{22}[/tex]

[tex]Probability = \frac{14}{506}[/tex]

[tex]Probability = \frac{7}{253}[/tex]
