Answer:
25°
Step-by-step explanation:
A triangle will always add up to 180 degrees when all angles are added.
So:
100 + 55 = 155
180 - 155 = ∠B
180 - 155 = 25
∠B = 25°
What's the equation of a line that passes through points (–1, –5) and (1, 3)?
y = 4x – 1
y = –2x
y = –x + 4
y = 14x – 2
Answers
Answer:
y=4x-1
Step-by-step explanation:
Answer:
y = 4x - 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 1, - 5) and (x₂, y₂ ) = (1, 3)
m = [tex]\frac{3+5}{1+1}[/tex] = [tex]\frac{8}{2}[/tex] = 4 , then
y = 4x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (1, 3 ) , then
3 = 4 + c ⇒ c = 3 - 4 = - 1
y = 4x - 1 ← equation of line

Find the scale factor of the similar shapes below.
Answers
Answer:
x=12 and the scale factor is 1.5
Step-by-step explanation:
From D' to F' is 7.5 and from D to F is 5cm the difference is 2.5. From F' to E' is x and from F to E is 8. This is just understanding what you can see. You find x by figuring out the ratio from 5 to 7.5 is and 8 to x or vise versa. It depends which way you are going. I think you are going from E,D,F to E',D',F'. So from 5cm to 7.5 cm. This is 1.5 because you are dividing 7.5/5. If you needed to find x, it would be 12.

In a math class with 19 students, a test was given the same day that an assignment
was due. There were 12 students who passed the test and 13 students who completed
the assignment. There were 4 students who failed the test and also did not complete
the assignment. What is the probability that a student completed the homework given
that they passed the test?
Answers
======================================================
Work Shown:
A = number who passed test, and did the hwB = number who passed test, but didn't do the hwC = number who failed test, but did the hwD = number who failed test, and didn't do the hwWith a class total of 19, we know that A+B+C+D = 19.
12 students passed the test, which leaves 19-12 = 7 people who failed the test.
Of these 7 people who failed the test, 4 of them didn't do the hw. This leads to D = 4.
Note how C+D = 7 becomes C+4 = 7 and it solves to C = 3.
Since 13 people did the hw, we can say A+C = 13. Plug in that value of C we found earlier, to find that A = 10.
Lastly, solving A+B = 12 leads to B = 2.
------------
To summarize what we found so far:
A = 10B = 2C = 3D = 4Now onto the question your teacher is asking: "What is the probability that a student completed the homework given that they passed the test?"
The key phrase here is "given that they passed the test". Because of this phrase, we'll ignore anyone who didn't pass. We'll focus solely on the 12 students who passed. Of those 12 who passed, we found that A = 10 people did the hw.
Therefore, the probability of picking someone who did the hw, given the passed the test, is 10/12 = 5/6

Which side lengths form a right triangle? please help
Answers
In a right triangle, the side that is opposite of the 90° angle is the longest side of the triangle, and is called the hypotenuse. The sides of a right triangle are commonly referred to with the variables a, b, and c, where c is the hypotenuse and a and b are the lengths of the shorter sides.
Rewrite in simplest terms: 7(-9a + 2a + 8) – 3a
Answers
Answer:
-63a+14a+56-3a
= -52a+56
Here we need to use algebraic properties to simplify an expression, we will get:
[tex]7\cdot (-9\cdot a + 2\cdot a + 8) - 3\cdot a = -52\cdot a + 56[/tex]
The mathematical property we need to use is the distributive property.
[tex]A\cdot (B + C) = A\cdot B + A \cdot C[/tex]
So we start with the expression:
[tex]7\cdot (-9\cdot a + 2\cdot a + 8) - 3\cdot a[/tex]
First, we use the distributive property in the first term so we get:
[tex]7\cdot (-9\cdot a + 2\cdot a + 8) - 3\cdot a \\\\= 7\cdot (-9)\cdot a + 7\cdot 2 \cdot a + 7 \cdot8 - 3\cdot a\\\\= -63 \cdot a + 14\cdot a + 56 - 3\cdot a[/tex]
Now we use the distributive property in the other way, we take "a" as a common factor:
[tex]-63 \cdot a + 14\cdot a + 56 - 3\cdot a\\\\= (-63 + 14 - 3)\cdot a + 56\\\\= -52\cdot a + 56[/tex]
Here we got the simplified expression.

Carla and Deserea bought a dozen cookies from the bakery. Carla ate ¼ of the cookies and Deserea ate ½ of the cookies. Who ate the most
Answers
Answer:
The answer is Deserea.
Step-by-step explanation:
Dont worry, this is simple :)
If you have a dozen cookies, that means you have 12 cookies!
And 1/4 of 12 is simply 12 divided by 4, which equeals 3, so Carla ate 3 cookies.
And Deserea ate ½ of the cookies, which is 12 divided by 2, which is 6! So Deserea ate 6 cookies.
6 is greater than 3. So Deserea ate more Cookies!
