Use the diagram and the given angle measure to find the other three measures.

m∠1=143∘

m∠2=

m∠3=

m∠4=

Answers

Answer:

angle 2 = 37⁰

angle 3 = 153⁰

angle 4 = 37⁰

Step-by-step explanation:

I guess this refers to two intersecting lines which form 4 angles.

Angles 1 and 2 are supplementary angles whose sum is 180⁰.

Angle 1 + angle 2 = 180⁰

143⁰ + angle 2 = 180⁰

angle 2 = 180⁰ - 143⁰

angle 2 = 37⁰

Angles 1 and 3 are vertical angles so do with angles 2 and 4. Therefore it is easy to find their measures because vertical angles are congruent in measures.

Hope this helps...

Answer:

m∠1 = 143°

m∠2 = 37°

m∠3 = 143°

m∠4 = 37°

Amelia and her brother had a snow day, so they played in the snow for 3 hours. During that time, it snowed another 4.8 inches. If the snow fell at a steady pace, how much snow fell each hour?

Answers

Answer:

1.6

Step-by-step explanation:

The amount of snow fell each hour is 1.6 inches per hour.

What is Unit Rate?

Unit rate is the amount of one quantity for a unit amount of the other quantity.

In other words it compares 1 unit of some quantity with different amount of another quantity

Given that,

Time Amelia and her brother played in the snow = 3 hours

Amount of snow fell at that time = 4.8 inches

That is 4.8 inches of snow per 3 hours

We have to calculate the unit rate of the amount of snow falling in an hour.

Amount of snow in 1 hour = 4.8 / 3 = 1.6 inches per hour

Hence the 1.6 inches of snow is falling per hour.

Hanna says you cannot represent the fraction 1/4 on the number line.

Answers

Answer:

The answer is D; Hanna is not correct,. The fraction 1/4 is equal to 2/8, so you can graph it on the second tick mark to the right of zero.

Step-by-step explanation:

Because the number line is broken up into 8 parts, the points on the graph are, 1/8, 2/8, 3/8, 4/8, 5/8, 6/8, 7/8, 8/8 (also known as one)

1/4 = 2/8. We know this because if we multiply 1/4 by 2, we get 2/8.

So, because 2/8 is the same as 1/4, we know that Hanna is not correct, and that you can graph 1/4 on this number line, because it is the same as 2/8.

I hope that this helps :)

The function f (x) = 6x + 13 defines a
sequence for x > 1. What are the first three
terms of the sequence?

Answers

Answer:

15, 21, 27

Step-by-step explanation:

Given the function :

f(x) = 6x + 13 ; which defines a sequence for x > 1

The first three terms of the sequence ;

x > 1 ;

Hence x = 2, 3, 4

The sequence :

f(2) = 6(2) + 3 = 12 + 3 = 15

f(3) = 6(3) + 3 = 18 + 3 = 21

f(4) = 6(4) + 3 = 24 + 3 = 27

find the slope and the y intercept of the points (0,1) and (2,-3)​

Answers

Answer:

The slope is -2 and y intercept is 1

Step-by-step explanation:

The slope is found by finding the run, or change in x coordinates from coordinate 1 to 2, which is 2 in this problem, and the rise, or change in y coordinates from coordinate 1 to 2, which is -4 in this problem. To find the y-intercept, you need to find the point on the line that has a x coordinate of 0, which is (0,1) on this line, which means the y-intercept is the y value of the coordinate, or 1.

State the solutions of the equation |x| + 2 = 4.

Answers

I think thats 2

Because 2+2=4

answer: 2 and -2

explanation: if you plug in 2 or -2 or x, then it would always become 2. this is because if you take the absolute value of any number, then it would become positive. this makes the equation true because 2 + 2 = 4

Like Ashoka and Gandhi, Akbar constructed a religious ideology that served to hold together a diffuse polity as it fed his own soul.It began with pragmatic policies of tolerance. Akbar had inherited the throne, at the age of 13, in 1556. In 1579 he abolished the jiziya, a tax imposed on all but the poorest non-Muslims. This was the most notable in a series of measures to recruit the Hindu majority and others to the cause of unifying and expanding his empire. He could be ruthless: his troops massacred 20,00025,000 non-combatants after a four-month siege of Chitor, a nearly impregnable Hindu fortress in Rajasthan. But he preferred incentives to coercion. He defeated the war-like Rajputs, but gave them rank and married their princesses, who were permitted to conduct Hindu rites in the harem.
