Can someone plzzzzz help me ASAP

Answer:

45°

Step-by-step explanation:

A and B are Alternate exterior angles and congruent, thus

5x - 15 = 2x + 21 ( subtract 2x from both sides )

3x - 15 = 21 ( add 15 to both sides )

3x = 36 ( divide both sides by 3 )

x = 12

Thus

∠ A = 5x - 15 = 5(12) - 15 = 60 - 15 = 45°

∠ B = 2x + 21 = 2(12) + 21 = 24 + 21 = 45°

Answer:

0.375

6/16

37.5%

Step-by-step explanation:

Can't be above 50% because that would be 4/8, which rules out 62.5%, 50%, and 3.75, and 3.75% is super low, which leaves 4 answers, but 1/4 doesn't equal any of the others. Also, 3/8 x 2 is 6/8, and 0.375 = 37.5%

Answer:

the final temperature is 39.0

Answer:

For part A its called a ray.For part B it would be EA.

Step-by-step explanation:

Part A would be called a ray because B is the endpoint while C is continuous and a ray has only one endpoint.Part B is EA because E would be the endpoint while A would be continuous.  

Answer:

3

Step-by-step explanation:

We know that -3 is on the x axis and 3 is on the y axis.

and the y axis usually determines if you are going to have a positive slope or negative since it would either rise or decrease. In this cause (-3, 3) shows that 3 is going to be our slope.

Answer:

y=3

Step-by-step explanation:

In a normal equation, y=mx+b, m=slope. If slope=0 in this equation, then it is safe to say that the equation is y=b. Since the Y coordinate is 3, then we can safely assume that the equation is equal to y=3

Answer:

4,4,64,larger,larger,would

Step-by-step explanation:

Begin by finding the dimensions of the poster. Since it is in the shape of a​ square, each edge will be the same length. and 16 divided by 4 is 4 and then you do 16 x 4 you get 64 and then you know is the box larger or not in this case the box is larger.

Answer:

A counterclockwise rotation of 270º about the origin is equivalent to a clockwise rotation of 90º about the origin. Given a point (4, 5), the x-value, i.e. 4 and the y-value, i.e. 5 are positive, hence the point is in the 1st quadrant of the xy-plane.

Answer:

1) 2/11

2) 2/121

Step-by-step explanation:

1. Because there are 2 E's, you have to chances out of your 11 changes, thus why the fraction 2/11 is the solution.

2. You know that 2/11 is the first fraction, so now find R. R has a 1/11 chance of getting chosen, so you multiply 2/11 and 1/11 to get 2/121.

Answer:

1) 2/11

2) 2/121

Step-by-step explanation:

Answer:

24 does not work as a common denominator because it is not the Lowest Common Multiple of 6, 4 and 5.

Step-by-step explanation:

In that above question, we are told that:

A student is trying to find the sum of 5/6 + 3/4 + 1/5

Step 1

The first step would be to find the Lowest Common Multiple of the denominators (6, 4, 5).

Lowest Common Multiple can be defined as the number that is the lowest quantity of the multiple of 2 or 3 number.

The lowest common multiple for 6, 4, 5 = 60. This is that number that the 3 denominators can be divided in

Hence,

5/6 + 3/4 + 1/5

= 5 × 10 + 3 × 15 + 12× 1/60

= 50 + 45 + 12/60

= 107/60

= 1 47/60

24 does not work because it is not the Lowest Common Multiple of 6, 4 and 5.

The lowest common multiple for the 3 denominators = 60, therefore 60 should be used.

Answer:

7.

Step-by-step explanation:

28 = 2^2 * 7.

To multiply 28 to get a perfect square, we can multiply it by 7 to get 2^2 * 7^2, which is 14 squared.

Step-by-step explanation:

Answer: sometimes

explanation:

if there are two points then there could be a line to connect them, however, there could always be two points that are separate on their own.

Answer:

Always

Step-by-step explanation:

If 2 distinct points lie on the plane then it determines the line. You can also verify if you can find the slope, with these 2 coordinate points, and then find the equation of the line but using point slop form and/or slope intercept form which is y=mx+b

Answer:

Step-by-step explanation:

x/3 = 14

x = 42

Step-by-step explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

From the question the equation of the line is

y = 3x - 4

Comparing with the general equation above

The slope /m = 3

The y intercept / c = - 4

Hope this helps you

Answer:

So it's going to be 3 times 2 minus 8 3 times 2 is 6 6 minus 8 is negative 2 and that's the answer.

Step-by-step explanation:

Answer:

Step-by-step explanation:

The direct proportion equation is y = kx which reads, "y is directly proportional to x". k is the constant of proportionality. In our case, we read this is as, "the number of calories is directly proportional to the number of apples eaten." Our equation would look like c = ka. We first are given that a = 4 and  = 380. We will use that to solve for k:

380 = k4 so

k = 95. Now that know the value of k, we will use that along with the number of calories (1045) to find the number of apples, a:

1045 = 95a so

a = 11

This means that it will be 11 apples that contain 1045 calories.

Number of hairs in day 1 , a = 5.

Every day number of hairs increases by , d = 4.

So, it is an Arithmetic Progression with first term a = 5 and common difference d = 4.

So, number of hair in nth days is given by :

[tex]a_n=a+(n-1)d\\\\a_n=5+(n-1)4[/tex]

Let, after x days number of hairs are 73.

[tex]73=5+(x-1)4\\\\x-1=\dfrac{73-5}{4}\\\\x=18\ days[/tex]

Therefore, Zider is 18 days old.

Hence, this is the required solution.
