Combine like terms to simplify the following polynomial.

6x + 7y – 9 – x + 8y + 5

A. 4x + 12y – 5
B. 42xy – 8xy – 45
C. 5x + 15y – 4
D. 13x + 7y – 4

Answer:

x = 32.6°

Step-by-step explanation:

Using the sine ratio in the right triangle

sin x = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{7}{13}[/tex] , then

x = [tex]sin^{-1}[/tex] ([tex]\frac{7}{13}[/tex] ) ≈ 32.6° ( to the nearest tenth )

Answer: 34.54feet

Step-by-step explanation:

Thw circumference of the pool will be calculated by using the formula:

= 2πr

where

π = 3.14

r = 5.5

Therefore, circumference = 2πr

= 2 × 3.14 × 5.5

= 34.54feet

Therefore, the circumference of the pool to the nearest hundredth is 34.54feet.

Answer:

8km

Step-by-step explanation:

The three points form a right-angled triangle with 15km as the height and 17km as the hypotenuse.

To find the distance between Lowell and the port which is the base use the pythagorean theorem.

=√17² - 15²

=8km

Answer:

Step-by-step explanation:

Percent increase:

A. Angle E = 113°

B. x = 16°

Number A

92 + 70 + 85 + ? = 360

162 + 85 + ? = 360

247 + ? = 360

? = 360 - 247

? = 113°

Number B

108 + 84 + ( x + 30 ) + ( 2x + 18 ) = 360

(180 + 84 + 30 + 18) + (x + 2x) = 360

312 + 3x = 360

3x = 360 - 312

3x = 48

x = 48/3

x = 16°

Answer:

it nonlinear i think

Step-by-step explanation:

on the x it goes from a 3 3/5 to 5 2/5 then drops down to ten.

we already know this is wrong because linear means going straight and proportional when displayed on a graph instead of having zigzag and sharko lines

The volume of the cone in terms of pi is 324π cubic cm.

Volume in mathematics describes how much space a three-dimensional item takes up. It is a measurement of the object's capacity, or the volume of fluid it can store. Typically, cubic units like cubic metres (m3) or cubic centimetres are used to determine an object's volume.

A three-dimensional object's shape affects the formula used to determine its volume. A rectangular prism's volume, for instance, can be determined by multiplying its length, width, and height.

The volume of the cone is given by the formula:

V = (1/3)πr²h

Now, for r = 9 and h = 12 we have:

V = (1/3)πr²h

V = (1/3)π(9²)(12)

V = 324π cubic cm

Hence, the volume of the cone in terms of pi is 324π cubic cm.

Answer:

1/8

Step-by-step explanation:

The probability of getting tails on a single flip is 1/2.

Each of the flips is an independent event so you must multiply the probability of getting tails on each flip together.

So, your answer will look like this

[tex]\frac{1}{2}[/tex] x [tex]\frac{1}{2}[/tex] x [tex]\frac{1}{2}[/tex] ; which equals;

1/8

Answer:

1/8

Step-by-step explanation:

To calculate the probability you have to name all possible results first. If you mark a result of a single coin flip as  H  for heads or  T  for tails all results of  3  flips can be written as:

Ω = { ( H , H , H ) , ( H , H , T ) , ( H , T , H) , ( H , T , T ) , ( T , H , H ) , ( T , H , T ) , ( T ,T , H ) , ( T , T , T ) }

Each triplet contains results on  1st,  2 nd and  3 rd coin. So you can see that in total there are  8  elementary events in  Ω.

| Ω |  =  8

Now we have to define event  A  of getting tails three times.

The only elementary event which satisfies this condition is  ( T , T , T )  so we can write that:

A  =  { ( T, T , T ) }

| A |  =  1

Now according to the (classic) definition of probability we can write, that:

P ( A )  =  | A|/  | Ω |  =  1 /8

So finally we can write the answer:

The Probability of getting 3 tails in 3 coin flips is  1 /8 .

Answer:

He is incorrect. He would need 225g of cocoa powder

Step-by-step explanation:

1. Lets calculate how much powder do we need per one cupcake, so 60 divided by 20, since 60g makes 20 cupcakes, 60/20 = we get 3g of cocoa powder per one cupcake.

2. Now we can multiply that by 75, 75*3=225, and 225g is more than 210g
