Find ac. Round to the nearest tenth

Answers

Answer 1

Answer:

Answer:

AC=6.37

Step-by-step explanation:

First you need to find m∠C

A triangle = 180 so you need to add 108 and 31

subtract 180-139

you get 41, so m∠C=41

Now we know all the angle measures.

Next we will use the law of sines

Go to google and type "law of sines calc"

google can usually provide with the formula and will even do the equation for you if you type in the numbers

So all you do is plug in the numbers and google will give you 6.37

A graph Includes the ordered pair (2,4). Write two different rulesA graph Includes the ordered pair (2,4). Write two different rules that would be possible for this graph. Explain how you found your answer.

Answers

All you have to do is make up some answers that when the ordered pair is substituted, it is a valid answer.

Here are some I made up:

$y=2x$

and

$y=x+2$

When substituting your ordered pair into this, it will be correct.

Apply the distributive property to create an equivalent expression.

(6e−3f−4)⋅2

Answers

Answer:

$12e-6f-8$

Step-by-step explanation:

We have been given an expression: $(6e-3f-4)\cdot 2$ and we are asked to create an equivalent expression by using distributive property.

To apply distributive property let us multiply each term in parenthesis by 2.

$6e* 2-3f* 2-4* 2$

Let us combine like terms.

$(6* 2)e-(3* 2)f-(4* 2)$

Now let us simplify our expression.

$12e-6f-8$

Therefore, expression $12e-6f-8$ is equivalent to our given expression.

(6e−3f−4)⋅2

Apply the distributive property

= 6e (2) - 3f (2) - 4(2)

= 12e - 6f - 8

Hope it helps.

Question #1:

The surface area of a prism is the area of the outside of the prism, the volume is how much the inside of the container holds.

Let's find the volume and surface area of the prism given.

V = lwh

Plug in what we know:

V = (18.4)(10.9)(8.7)

Multiply:

V = 1744.872 m^3

SA = 2(wl + hl + hw)

Plug in what we know:

SA = 2((10.9)(18.4) + (8.7)(18.4) + (8.7)(10.9))

Multiply:

SA = 2(200.56 + 160.08 + 94.83)

Add:

SA = 2(455.47)

Multiply:

SA = 910.94 m^2

Now find the difference:

Note that these are different measurements.

The volume is measured in cubic meters and the surface area is measured in square meters.

910.94 m^2 = 27493.793 m^3

Find the difference:

27493.793 m^3 - 1744.872 m^3 = 25748.921

Question #2:

The formula for the surface area of a rectangular prism is:

SA = 2(wl + hl + hw)

Plug in what we know:

SA = 2((5)(6) + (3)(6) + (3)(5))

This is the equation we use to find the surface area of this figure.

Multiply:

SA = 2(30 + 18 + 15)

Add:

SA = 2(63)

Multiply:

SA = 126 cm^2

Chet's father is five times as old as Chet. In six years, his father only be three times as old. How old is Chet now?

Answers

12 bc if u take a random number like 6 times it by 5 you get thirty so his dad is 30 years old and chet is 6 then add six years and chet is 12 and his dad is 36 and 12 goes into 36 3 times. I hope this helped. :-)
