find AC A.6 B.12 C.16 D.10

Answer:72.9

Step-by-step explanation:

Answer:

72.9

Step-by-step explanation:

Fractions method:

[tex]81*\frac{90}{100}[/tex] because 90/100 is the same thing as 90%

That gives us 7290/100, from 81*90/100

Simplify: =729/10 = 72.9

Decimals method:

81*9 = 729, add in decimal and that's 72.9

Cross-multiplication:

90    100

?         81

This is read as 90 to 100, (as a ratio) so how many to 81? To solve, cross-multiply - 81*90=7290, then divide by 100 to get 72.9.

Step-by-step explanation:

To find the equation of the line given a point and slope we use the formula

[tex]y - y_{1} = m(x - x _{1})[/tex]

where

m is the slope

( x1 , y1) is the point

From the question

The point is (6, 8) and

slope - 2

The equation of the line is

[tex]y - 8 = - 2(x - 6) \\ y - 8 = - 2x + 12 \\ y = - 2x + 12 + 8[/tex]

Answer:

x = [tex]\frac{11}{3}[/tex]

Step-by-step explanation:

Given

[tex]\frac{2}{3}[/tex] = [tex]\frac{x-1}{4}[/tex] ( cross- multiply )

3(x - 1) = 8

3x - 3 = 8 ( add 3 to both sides )

3x = 11 ( divide both sides by 3 )

x = [tex]\frac{11}{3}[/tex]

Answer:

12¢

Step-by-step explanation:

Let the unit price of a pencil be x and the unit price of a pen be y.

2x+3y=78¢

3x+2y=72¢

(2x)+3y=78¢

(3x)+2y=72¢

=2x=78¢-3y

=2x/2=78¢/2+3y/2

=x=36¢-1.5y

You then use the equation 3x+2y=72¢.

3(36¢-1.5y)+2y=72¢

=117¢-4.5y+2y=72¢

=117¢-72¢=4.5y-2y

=45¢=2.5y

=45¢/2.5=y

=18¢=y

So a pen costs 18¢.

You then use x=36¢-1.5y

x=36¢-1.5(18¢)

=x=36¢-27¢

=x=12¢

Therefore, a pencil costs 12¢.

Answer:

y=12x/5

x=5y/12

Step-by-step explanation:

y:3x-y=4

y=4(3x-y)

because if there is divide sign if it will go to another side it will be multiply

y=12x-4y

y+4y=12x

5y=12x

y=12x/5

or, x=5y/12

I think a spinner is not a type of probability model.

I am not sure tho

Option (c) A spinner is not a probability model

A probability model is a mathematical representation of a random phenomenon.

Here,

In systematic list, the outcomes for an event can be listed in an organized or systematic way to make sure that none of the possible outcomes is missed out.

In area model, area models can be used to represent simple probabilities.

A probability tree diagram is used to represent the probability of occurrence of events without using complicated formulas.

The value of x in the expression will be 100.

A line segment in geometry is a section of a line that has two clearly defined endpoints and contains every point on the line that lies within its confines.

Given that FG = (2x) meters, GH = 1,000 meters, and FH = 1,200 meters,

The value of x will be calculated by making an equation for the line segment below:-

FG + GH = FH

2X+1000=1200

2X = 1200 - 1000

2X = 200

X = 100 meters

2X + 1000= 1200

Therefore, the value of x in the expression will be 100.

Answer:8

Step-by-step explanation: she makes $100 a day so you would subtract that from the total (276) then you would divide the remainder (176) by the amount she makes an hour (22) then you would end up with 8 hours

Answer:

8 hours

Step-by-step explanation:

For $22=1 hour

For $1=1/22 hours

For $176=176/22 hours=8 hours

And she gets also $100 extra

So for $276 she works 8 hours.

Answer:

Square root 8 over three, (square root of 4)/2, and pi/3.

Step-by-step explanation:

First of all, square the radicals to make solving this easier. Squarer root 8 over three will become 8/9, and square root 4 over 2 will now become 4/4, which is 1. Pi/3 is greater than 1, so we can now order this from least to greatest. 8/9 is the least, 1 is the second greatest value, and pi/3 is the greatest value.

Answer: 8squared/3 4squared/2 Pi/3

Step-by-step explanation:

8 squared = 2.8... = 2.8/3 (least)

4 squared = 2 = 2/2 = 1 (second least)

Pi over 3 = 3.14159.../3 = 1 .14159/3 (greatest)

Step-by-step explanation:

Angle A = 4x + 12 = 4(15) + 12 = 72°.

Acute is for angles that are less than 90°.

Obtuse is for angles that are between 90° and 180°, not inclusive.

Right is for angles that are 90°

Hence the answer is acute.

The angle is an acute angle

An acute angle is an angle that is less than 90 degrees

An obtuse angle is an angle that is greater than 90 degrees and less than 180 degrees

In order to determine which type of angle it is, solve for angle A

4x + 12

4(15) + 12

60 + 12 = 72

The angle is acute because it is less than 90 degrees

Answer:

[tex]\frac{m^3}{2} - 4[/tex]

Step-by-step explanation:

Required

Determine an expression for the given statement

The expression can be rewritten as:

one-half    *     the cube of m       subtracted by      4

Convert each statement to mathematical expressions:

One half = [tex]\frac{1}{2}[/tex]

The cube of m = [tex]m^3[/tex]

one-half    *     the cube of m = [tex]\frac{1}{2} * m^3[/tex]

At this stage, we have:

[tex]\frac{1}{2} * m^3[/tex] subtracted by 4

This gives:

[tex]\frac{1}{2} * m^3 - 4[/tex]

[tex]\frac{m^3}{2} - 4[/tex]

Hence, The corresponding expression is [tex]\frac{m^3}{2} - 4[/tex]

One-half the cube of m subtracted by 4 is [tex]0.5\sqrt[3]{m} -4[/tex]

Based on the information given, one-half the cube of m subtracted by 4 is expressed as:

Subtracting 4 from the result will give the final expression as [tex]0.5\sqrt[3]{m} -4[/tex]
