Can you guys plz help me

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

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

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:

Answer:

Step-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: the answer is b=1

The 4 angles inside EVERY 4-sided figure ALWAYS add up to 360 degrees.

Now you have been found !

Answer:

25) B obtuse scalene

26) A acute isosceles

27) A acute isosceles

28) D obtuse isosceles

29) D right scalene

30) C obtuse isosceles

31) C obtuse scalene

32) C acute scalene

Step-by-step explanation:

A scalene triangle has sides of no equal measures (no side has the same length as another). An isosceles triangle has two sides of the same length. An equilateral triangle has three sides that all have the same lengths.

An acute triangle has all three angles that each measure less than 90°. An obtuse triangle has one angle that measures greater than 90°. A right angle has one angle that measures exactly 90°.

Hope this helps :)

Answer:

I am pretty sure the answer would be 51 feet

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.

Answer:

40

Step-by-step explanation:

The Interior of a triangle adds up to 180. 180 - 90 - 50 = 40

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.

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

Answer:

Give me some time let me do it

Answer:

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)

Answer:

∴x=-11.5625

Step-by-step explanation:

110 = -8 (2x+9 ) -3

110 = -16x - 72 -3

185 = -16x

∴x=-11.5625

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

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
