HELP!!!!!!!!!!!!!!!!!!!!!!!
Answer:
79
Step-by-step explanation:
m<1 = 90 -38 = 52
m<3 = 90 - 52 = 38\
m<2 = 180-38-63 = 79
Answer:
Step-by-step explanation:
<1 + <3 = 90 Parallel lines produce interior angles that add to to 90
<1 + 38 = 90 Substitution
<1 = 90 - 38 52
<3 = 90 - 52
<3 = 38
38 + 63 + <2 = 180 Sum of angles in a triangle always = 180
101 + <2 = 180
<2 = 79

A number to the 8th power divided by the same number to the 6th power equals 64. What is the number?
The number is
Answer:
4
Step-by-step explanation:
Let the number = X
You have X^8 / X^5
When dividing two numbers with powers, Simplify the expression by subtracting the powers.
8-5=3
so X^8 / X^5 becomes x^3
Now you have x^3 = 64
To find x take the cubic root of 64:
X = ∛64
X = 4
The number is 4
Write the equation of the piecewise function. Algebra 2
Answer:
C. [tex]y=\begin{cases}2-x&x<0\\5-3x&x\ge 0\end{cases}[/tex]
D. [tex]y=\begin{cases}-2&x<-3\\4&x>-3\end{cases}[/tex]
Step-by-step explanation:
C. The line to the left of x=0 has a slope of -1 and a y-intercept of 2. That portion of the function does not include x=0. The line to the right of x=0 has a slope of -3 and a y-intercept of 5. That portion of the function includes the case x=0.

12. Given y-3 = (x + 1), convert it to standard form.
Answer:
x - y = -4
Step-by-step explanation:
Standard Form: Ax + By = C
A is non-negative
Step 1: Define equation
y - 3 = (x + 1)
Step 2: Solve to Standard Form
Add 3 to both sides: y = x + 4Subtract x on both sides: y - x = 4Factor out negative: -(x - y) = 4Divide by -1 on both sides: x - y = -4

the base of the tringle would be 8 and the height would be 7 use pythagorus
Answer:
≈ 10.6 units
Step-by-step explanation:
Calculate the distance d using the distance formula
d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = p(3, - 1) and (x₂, y₂ ) = q(- 5, 6)
d = [tex]\sqrt{(-5-3)^2+(6+1)^2}[/tex]
= [tex]\sqrt{(-8)^2+ 7^2}[/tex]
= [tex]\sqrt{64+49}[/tex]
= [tex]\sqrt{113}[/tex] ≈ 10.6 ( to 1 dec. place )

Here's the general rule for rounding: If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up. Example: 38 rounded to the nearest ten is 40. If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down.
Find the distance between the two points rounding to the nearest tenth (if necessary).

To measure a stone face carved on the side of a mountain, two sightings 700 feet from the base of the mountain are taken. If the angle of elevation to the bottom of the face is 35 and the angle of elevation to the top is 38 , what is the height of the stone face?
Answer:
75feet

To measure a stone face carved on the side of a mountain, two sightings 700 feet from the base of the mountain are taken. If the angle of elevation to the bottom of the face is 35 and the angle of elevation to the top is 38 , what is the height of the stone face?
Iet us say we have two right triangles. With a base of 700. The first has angle of 35o and the other has an angle of 38degree
Then we need the Height
From trigonometry
Tan = opposite/adjacent.
In this case the adjacent is 800
Tan 35 = 0.7002
Tan 38 = 0.781

A It remains the same
B It doubles
C It halves
D Not enough information
Select the equivalent expression.
Answer:
The answer is B
Step-by-step explanation:
This is because when you distribute the -4 to 9^6 and 7^-24 you will get 9^-24 and 7^36. Then, you can move the 7^-24 to the denominator because of the negative exponent rule.

Bruce owns a business that produces widgets. He must bring in more in revenue than he pays out in costs in order to make a profit. • It costs $10 in labor and materials to make each of his widgets. • His rent each month for his factory is $4,000. He sells each widget for $25. What is the smallest number of widgets Bruce needs to sell each month to make a profit?
Answer:
Bruce needs to sell 267 widgets each month to make a profit.
Step-by-step explanation:
From the information given, you can write that the cost of the monthly rent plus the cost in labor and materials to make each widget for the number of widgets is equal to the amount of sales:
10x +4000 = 25x
Now, you can solve for x:
4000 =25x-10x
4000=15x
x= 266.67→267
According to this, the answer is that Bruce needs to sell 267 widgets each month to make a profit.
Which statement that describes show that figure a is congruent to figure b
Answer:
E.
Step-by-step explanation:
Translation: slide of the shape or figure, it does NOT change its shape, size, and form, count how many units the shape moves.
Reflection: flip of the shape, does NOT change its shape, size, and form, either can be flipped or reflected over the x or y axis.
Rotation: turn of the shape, does NOT change its shape, size, and form, either can be rotated counter clock wise left, (opposite of a clock direction), or clockwise, the direction a clock moves right. It can also be rotated 90° (1 turn), 180° (2 turns), 270° (3 turns) or 360° (4 turns). In highschool, you will get introduced to more degrees of rotation, this is just middle school level.
Solve for the letter A. ab+d=c
Answer:
a=c/b-d/b
Step-by-step explanation:
Answer:
a=c-d/b
Step-by-step explanation:
We first need to isolate the variable "a" by doing the opposite operation.
1. subtract "d" on both sides
After step 1- ab=c-d
2. divide both sides by "b" because that is the only way to isolate a permanently
After step 2- a=c-d/b
