Need help, 40 points.
Answer:
m∠1 = 94°
m∠2 = 43°
m∠3 = 50°
m∠4 = 50°
m∠5 = 130°
m∠6 = 130°
Step-by-step explanation:
Answer:
m<1 = 80 degrees
m<2 = 57 degrees
m<3 = 57 degrees
m<4 = 43 degrees
m<5 = 137 degrees
m<5 = 123 degrees
Step-by-step explanation:
Angle 1: Vertical angles
Angle 2:
43+80 = 123, 180-123 = 57
Angle 3: Corresponding to m<2
Angle 4: Corresponding to the 43 degree angle
Angle 5: m<1 + m<2 = 137 degrees (Corresponding)
Angle 6: m<3+m<6 = 180 degrees. 180-57=123
–3(2y–9)?
a
n
s
w
e
r
Answer:
-6y+27
Step-by-step explanation:
-3*2y=-6y
-3*-9=27
because multiplying 2 negatives make a positive.
so,
-3(2y-9) = -6y+27
Juan read for ⅚ of an hour, Larissa read for 10/12 of an hour. Who read for a longer period of time?
Answer: They read for a equal amount of time.
Step-by-step explanation:
10/12 simplifies to 5/6, making these equal.

Spencer bought 3 books of stamps and mailed a package. It cost 4.50 to mail the package. Define a variable and write an expression to represent the total amount he spent at the office.
if 3 is added to a number and multiplied the result by 5 gives 55 what is the number
Answer:24
Step-by-step explanation:Let the number we seek be X.
We are Given:
1). (5X+3 ) x (2) = 30
Expand and Rearrange.
(10X +6 ) = 30.
10X = 24.
2). X equals 2.4 . This is the answer for the number we seek.
Always check the answer.
This is Good Working Practice ALWAYS.
For Exams or similar remember:
Presentation (Neat & Tidy), Method & Layout (Show you understand), Accuracy.
All these count in most exams.
The first two points help greatly if your Answer is in error, but your METHOD Is CLEAR & CORECT.
Similarly, if the Check is wrong, mention this, but also, if the case, mention e.g. time ran out .. You may be credited as AWARE if your presentation and Method show you understood what to do and why.
CHECK: Substitute the answer for X into the original equation 1).
Equn. 1). (5X +3)*2 = 30.
Put in the value for X. Expand & Re-arrange.
(( 5 ).( 2.4 ) + ( 3 ).( 2 ) = 30.
( 12 + 6 ) = 30.
24 = 24. Checked & Agreed.
That’s about it.

Find the nth term: 8, 18, 28, 38, 48....
Answer:
The ninth term? That would be 98.
Step-by-step explanation:
Notice how the numbers add 10 every time. If we keep doing that pattern until we get the ninth number, then we get this:
8, 18, 28, 38, 48, 58, 68, 78, 88, 98
Therefore, the answer is 98.
Zack wants to make a profit of more than $300 for painting 4 identical rooms. The profit he makes is equal to the amount he is paid minus the cost of supplies. The cost of supplies is $32.50 for each room. Which inequality and solution represent the dollar amount that Zack must be paid for each room if he is to make a profit of more than $300P 4(n - 32.8) > 1,200; n > 332.5 4(n - 32.5) > 300;n > 107.5 C An - 32.8 > 300; n > 83.123 n- 4(32.5) > 300;n > 430
Please help I have less than 30 mins to get this done!!
Answer:
n-4(32.5) > 300;n > 430
Step-by-step explanation:
Simplify: 300 = 4n - 130
Add 130 to each side. 430 = 4n
Divide by 4 on each side: 107.50= n
300 = 4(107.50) - 130? True
This tells us he must be paid $107.50 to make $300 exactly. Anything larger than $107.51 and up will make more than $300.

Find the length of the
missing side of the triangle
to the nearest tenth.
Answer: 15
Step-by-step explanation:
For this question you have to use pythagoras' theorem.
Pythagoras' theorem is c²=a²+b²
So c is the hypotenuse and the hypotenuse is always opposite the right angle.
So the equation would be c²=9²+12²
Then 9²=81 and 12²=144
So the equation would then be c²=81+144
So c²=225
Then you just want to find c on it's own so you have to square root it which is 15.

The measure of Angle 1 is 35º and it is complementary to Angle 2. The
measure of Angle 2 is 5x. What is the value of x?
Answer:
x = 11
Step-by-step explanation:
35 + 5x = 90 {Complementary angles}
Subtract 35 from both sides
5x = 90 - 35
5x = 55 {Divide both sides by 5}
x = 55/5
x = 11

Which expression is equivalent to
7x+4X^2- 5x?
A 4x^2+ 10x
B 2x + 4x^2
C 2x - 4x^2
D 4X^2 - 2x
Answer:
B
Step-by-step explanation:
Combine like term.
Hers 7x and (-5x) are like terms
7x + 4x² - 5x = 7x - 5x + 4x²
= 2x + 4x²

Explain how you got the answer Please
Answer:
Step-by-step explanation:
Remark
The diameter is 28 cm
Formula
Area = pi * r^2
Givens
pi = 22/7
r = d/2
r = 28/2
r = 14
Area = 22/7 * 14 * 14
Area = 22 * 2 * 14
Area = 44 * 14
Area = 616
arcsin0=? arccos0=? arctan1=?
Answer:
arcsin0= 0 degrees
arccos0= 90degrees
arctan1= 45 degrees
Step-by-step explanation:
To get arcsin0, let the unknown value be x
sin x = 0
Take arcsin of both sides
arcsin(sinx) = arcsin 0
x = arcsin0
x = 0 degrees
Hence arcsin0 = 0degrees
For cos x = 0
Take arccos of both sides
arccos(cosx) = arccos 0
x = arcscos0
x = 90 degrees
Hence arccos0 = 90degrees
For tan x = 1
Take arctan of both sides
arctan(tanx) = arctan 1
x = arctan1
x = 45 degrees
Hence arctan1 = 45degrees

Solve the equation: 12(x + 8) = 11x - 5 What is the solution?
Answer:
We conclude that the solution is:
[tex]x = -101[/tex]Step-by-step explanation:
Given the equation
[tex]12\left(x\:+\:8\right)\:=\:11x\:-\:5[/tex]
Expand 12(x + 8): 12x + 96
[tex]12x+96=11x-5[/tex]
Subtract 96 from both sides
[tex]12x+96-96=11x-5-96[/tex]
Simplify
[tex]12x=11x-101[/tex]
Subtract 11x from both sides
[tex]12x-11x=11x-101-11x[/tex]
Simplify
[tex]x=-101[/tex]
Therefore, we conclude that the solution is:
[tex]x = -101[/tex]
