I really don’t know how to do it.

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

Answers

Answer/Step-by-step explanation:

1. <ABC and <BCD are alternate interior angles. Alternate interior angles are equal, therefore, since m<ABC = 38°, then m<BCD = 38°

2. m<ECF = m<BCD (corresponding angles)

m<ECF = 38° (substitution)

3. m<DCF + m<ECF = 180° (linear pair)

m<DCF + 38° = 180° (substitution)

m<DCF = 180° - 38° (Subtraction property of equality)

m<DCF = 142°

The measure of the following angles are as follows;

∠BCD = 38°

∠ECF = 38°

∠DCF = 142°

Angles form when a transversal cut parallel lines

When a transversal line cut across parallel lines, the angles form include corresponding angles, alternate angles etc.

Therefore,

∠BCD = 38 degrees(alternate angles)

∠ECF = 38 degrees(corresponding angles)

∠DCF = 180 - 38 = 142 degrees(angles on a straight line)

Step-by-step explanation:The statement which describes the meaning of the slope is " The boiling point decreases by 1.8 degrees as the altitude increases by 1,000 feet " ⇒ D

Step-by-step explanation:

The boiling point of water (measured in degrees), at altitude (measured in feet), is modeled by the function T(a) = −0.0018 a + 212, where

a is the altitude measured in feet

T(a) is the boiling point of water in degree

The form of the linear function is f(x) = mx + b, where m is slope (the rate of change), and b is the y-intercept (the value of f(x) at x = 0)

By comparing between the form of the function and the given function

∴ m = -0.0018 ⇒ degrees per foot

∵ The sign of the slope is negative

∵ The slope = Δf(x)/Δx

- That means T(a) is decreasing function

∴ The boiling point is decreases when the altitude increasing

∵ -0.0018 =  degrees per feet

∴ The boiling point decreases by 18 degrees as the altitude

   increases by 10,000 feet or the boiling point decreases by 1.8

    degrees as the altitude increases by 1,000 feet

The statement which describes the meaning of the slope is " The boiling point decreases by 1.8 degrees as the altitude increases by 1,000 feet "

Step-by-step explanation:

Since AB and CD are straight lines, vertical angles formed by them are congruent. Angle DOB is equal to angle AOC which is equal to 2x. Since you know that a straight angle is equal to 180 degrees, you can say :

2x + 90 + x = 180

3x + 90 = 180

3x = 90

Question 1: Write an equation.


Question 2: How long will the job be when both companies will cost the same amount?


Question 3: How much will they charge?

Answers

Answer:

BelowI hope it helps ♥

Step-by-step explanation:

1.  Equation representing when both companies will cost the same amount :

[tex]350 + 15x = 275 + 20x[/tex]

2. Let x equal the number of hours a job takes , then the first house painting company will charge 350+15x , the second house painting will charge 275 +20x. If the two companies charge the same amount , we will have;  

[tex]350 +15x = 275+20x\\\\350 - 275 = 20x - 15x\\\\75 = 5x\\\\\frac{75}{5} = \frac{5x}{5} \\\\15 = x\\\\x = 15\:hours[/tex]

3. For a job that takes 15 hours , the first company will cost ;

[tex]350 + 15(15) = 575[/tex]

Kelly purchased 6 equally-priced CDs for a total of $75.30 what is the cost per CD?

Answers

Answer:

$12.55 per CD

Step-by-step explanation:

If each CD is of equal price, you must then divide the price by the number of CD's. (75.30/6=12.55)

Answer:

$75.30/6 = $12.55 per CD

Step-by-step explanation:

Since the CDs are equally-priced, my thought is that you would divided the quantity that you purchased by your total to get your answer. So, your total, $75.30 divided by, the amount of CDs purchased, 6. This would lead you to the answer $12.55, which is the cost of each CD. To check your answer you would multiply $12.55 by 6 to get $75.30.

what is
5y+3=4y+8=146

Answers

Answer: y=15

Step-by-step explanation:

Solution for (5y+3)+(4y+8)=146 equation:

Simplifying

(5y + 3) + (4y + 8) = 146

Reorder the terms:

(3 + 5y) + (4y + 8) = 146

Remove parenthesis around (3 + 5y)

3 + 5y + (4y + 8) = 146

Reorder the terms:

3 + 5y + (8 + 4y) = 146

Remove parenthesis around (8 + 4y)

3 + 5y + 8 + 4y = 146

Reorder the terms:

3 + 8 + 5y + 4y = 146

Combine like terms: 3 + 8 = 11

11 + 5y + 4y = 146

Combine like terms: 5y + 4y = 9y

11 + 9y = 146

Solving

11 + 9y = 146

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Add '-11' to each side of the equation.

11 + -11 + 9y = 146 + -11

Combine like terms: 11 + -11 = 0

0 + 9y = 146 + -11

9y = 146 + -11

Combine like terms: 146 + -11 = 135

9y = 135

Divide each side by '9'.

y = 15

If Syn spends 15 minutes running, he burns 200 calories. How long will it take Syn to burn 150 calories?

Answers

Answer:

11 minutes and 15 seconds (11.25 minutes/ 11 and 1/4)

Step-by-step explanation:

create the corresponding ratio by dividing 200 by 15, 200 calories per 15 minutes. Which equates to 40 calories every three minutes which means 40/3 or 13 1/3 calories every minute. You can verify this by multiplying 15 and 40/3 to get 200 again.

The last step is to divide the calories burned by the corresponding ratio (40/3)

150/(40/3) = 11.25

and .25 or 1/4 of 60 seconds(in a minute) is 15 since 60/4 = 15.
