What is the measure of an exterior angle of a regular 45-gon?
Answer:Sum of exterior angle of any polygon is 360o . As each exterior angle is 45o , number of angles or sides of the polygon is 360o45o=8 . Further as each exterior angle is 45o , each interior angle is 180o−45o=135o .
Step-by-step explanation: hope this helps ;)
Answer:
8
Step-by-step explanation:
6- 4(2r - 5) < 26 - 8r
This is algebra
Answer:
r>1
Step-by-step explanation:
6-4(2r-5)<26-8r do () first
6-8r+20<26-8r subtract 6 from both sides
-8r+20<20-8r Since this is the same on both sides, r>1 to make the equation not come out as 0

110=-8(2x+9)-3 this is urgent HELP
Answer:
∴x=-11.5625
Step-by-step explanation:
110 = -8 (2x+9 ) -3
110 = -16x - 72 -3
185 = -16x
∴x=-11.5625
which expression can be an integer when simplified? i will give so many points and brainliest plz answer!
a.6^-3/6^-1
B. 12^-2/12^2
C. 2^-10 x 2^3
D. 4^7 X 4^-2
Answer:
D
Step-by-step explanation:
when simplify 4^7, using a calculator, you get 16384. When you simplify 4^-2 , you get 0.0625. When multiplied together, the total is 1024, which is an integer. Answer a, b, and c were not integers, because when multiplied or divided, the answer was less than zero and showed up as a decimal starting with 0.*** . An integer is defined as any whole number, and not a fraction, therefor D is the only correct answer.

Based only on the information given in the diagram, which congruence
theorems or postulates could be given as reasons why AJKL= AQRS?
Check all that apply.
O A. HL
B. SAS
O C. LL
O D. HA
D E. LA
F. SSS
Answer: HL, SAS, LL, SSS
Step-by-step explanation:
its that easy
ΔJKL and ΔQRS are congruent by HL, SAS, SSS, and LL postulates.
Options A, B, C, and F are the correct answer.
What is triangle congruency?
There are ways to prove that two triangles are congruent.
- Side-Side-Side (SSS) Congruence.
The three sides of one triangle are equal to the corresponding three sides of another triangle.
- Side-Angle-Side (SAS) Congruence.
The two sides and the included angle of one triangle are equal to the corresponding two sides and included angle of another triangle.
- Angle-Side-Angle (ASA) Congruence.
The two angles and the included side of one triangle are equal to the corresponding two angles and included side of another triangle.
- Angle-Angle-Side (AAS) Congruence.
We have,
LL congruency
Two triangles are said to be congruent under LL congruence if they have two pairs of corresponding sides that are equal in length and the included angles between these pairs of sides are also equal.
HL congruency
If two right triangles have the same hypotenuse and one corresponding leg, then the two triangles are congruent (have the same shape and size).
Now,
The two triangles are right triangles.
So,
From the definition of congruency, we can say,
ΔJKL and ΔQRS are congruent by:
HL, SAS, SSS, and LL.
Thus,
ΔJKL and ΔQRS are congruent by HL, SAS, SSS, and LL postulates.

Find the amplitude, the EoA=y, the period, and the phase shift in terms of cosine for this graph.
Answer:
Step-by-step explanation:
or
Step-by-step explanation:
has:
1) amplitude=|a|
2) phase shift=b
3) period=2pi/c
d) vertical shift=d
--------------------------------------------------
You are given the amplitude is 2. This means a could either be 2 or -2.
You are given phase shift is -1/8. This means b is -1/8.
You are given the period is pi. So we need to solve pi=2pi/c.
pi=2pi/c
Dividing both sides by pi gives:
1=2/c
Multiply both sides by c gives:
c=2
The vertical shift is -2 so d=-2.
The equation could either be:
y=2cos(2(x-(-1/8)))-2
or
y=-2cos(2(x-(-1/8)))-2
Simplifying a little gives:
y=2cos(2x+1/4)-2
y=-2cos(2x+1/4)-2
The sum of two consecutive integers is two more than the third integer. Find the integers
Answer:
3, 4, 5Step-by-step explanation:
x - the first integer
x+1 - the next integer consecutive to x (the second consecutive integer)
x + x+1 - the sum of two consecutive integers
x+1+1=x+2 - the integer consecutive to x+1 (the third consecutive integer)
x+2 + 2 - two more than the third integer
x + x+1 = x+2 + 2
2x + 1 = x + 4
x + 1 = 4
x = 3
x+1 = 3+1 = 4
x+2 = 3+2 = 5

Answer:
f = 2
Step-by-step explanation:
Hope this helps you! :3
Answer:
f = 2
Step-by-step explanation:
2+1.25f = 10 - 2.75f
Add 2.75f to both sides
2 + 4f = 10
Subtract 2 on both sides
4f = 8
Divide by 4 on both sides to isolate the variable f
f = 8/4
f = 2
solve for w and simplify the answer
Answer: w=20/3
Step-by-step explanation: start by multiplying -3/2 by 2 and multiply -10 by 2 as well. you would get -3w = -20. divide both sides by -3 and you’ll get 20/3.
Smith & Johnson produces a variety of men’s clothing. Their highest selling items are their fitted dress shirts. The profit earned from the sale of these shirts can be modeled by the expression -20x2+1,800x, where x is the price of one dress shirt. If p is the maximum profit earned from the sale of the dress shirts, write an equation that shows how the expression can be rewritten to model the price at which the shirts should be set in order to maximize profit.
Answer:
P=x(-x+90)Step-by-step explanation:
Step one:
given
Price
[tex]P= -20x^2+1800x[/tex]
where P is the maximum profit
x is the price of one shirt
Step two:
To rewrite the expression let us first divide through by 20
[tex]P= \frac{-20x^2}{20} +\frac{1800x }{20}\\\\P=-x^2+90x[/tex]
Factoring x out we have
[tex]P=-x^2+90x\\\\P=x(-x+90)[/tex]
Hence the rewritten expression equation for the price is
P=x(-x+90)

If you have a square with a perimeter of 18 inches, what is the area of the square after
scaling it by 7? Round to the nearest tenth is needed.
Answer:
992.3 in^2 to the nearest tenth.
Step-by-step explanation:
The new perimeter will be 7*18 = 126 inches.
So the side of the new square will be 126/4 = 31.5 inches,
and it's area = 31,5^2
= 992.25

Which equation is parallel to CD which passes through through points C (-3,4) and D (7,-2)?
Answer:
y = - [tex]\frac{3}{5}[/tex] x + 1
Step-by-step explanation:
Parallel lines have equal slopes
Calculate m of CD using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = C(- 3, 4) and (x₂, y₂ ) = D(7, - 2)
m = [tex]\frac{-2-4}{7+3}[/tex] = [tex]\frac{-6}{10}[/tex] = - [tex]\frac{3}{5}[/tex] , thus
y = - [tex]\frac{3}{5}[/tex] x + 1 ← is parallel to CD
