Answer:

12

Step-by-step explanation:

[tex]4 \sqrt{9} [/tex]

[tex] \sqrt{9} = \sqrt{ {3}^{2} } = 3[/tex]

[tex]4 \times 3[/tex]

[tex] = 12[/tex]

Step-by-step explanation:

Not sure if I'm right or not but I think your question is

6/4 + 8/4

so I'll solve now

6/4 + 8/4 .........look for the common denominator (4)

6+8/ 4

14/ 4

In decimals = 3.5

In fractions =7/2

Answer:

Step-by-step explanation:

200=2w²h

The equations are -

200 = 2[tex]w^{2}[/tex]h

2w x w x h = 200

We have a prism and the formula to calculate its volume is given.

We have to select all of the equations that rewrite the volume formula by making substitutions for V = 200 cubic centimeter and L = 2w.

A Prism is a three-dimensional shape, which consists of two identical polygons, which do not lie in the same axis.

According to the question, we have -

Volume of Prism = 200 cubic centimeter

L = 2w

The formula to calculate the volume of prism equals to -

V = Lwh

Substituting values, we get -

200 = 2[tex]w^{2}[/tex]h

or

2w x w x h = 200

Hence, the equations are -

200 = 2[tex]w^{2}[/tex]h

2w x w x h = 200

Hi ;-)

[tex]u+51^o=79^o\\\\u=79^o-51^o\\\\\huge\boxed{u=28^o}[/tex]

The required equation is,

→ 51° + U = 79°

Now we should,

find the required value of U.

→ 51° + U = 79°

→ U = 79° - 51°

→ [U = 28°]

Let's check whether the required value of U is correct or incorrect,

→ 51° + U = 79°

→ 51° + 28° = 79°

→ 79° = 79°

→ LHS = RHS

Hence, 28° is the required value of U.

Answer:

Read explanation Please (I spent alot of time on it and its important to understand where the answer came from not just the answer!)

Step-by-step explanation:

This problem is in the form of y=mx+b where m is the ratio y grows accordinly to x and b is the value of y when x is 0 (mx0 is 0, 0+b is b).

In you problem we can identify that 1 is the y intercept or when x is 0. All we have to do is find another point since 2 points make alike. Let's say x was 1. 43 * 1 +1 = 44 so when x is 1 y is 44.

Our two points are, (0,1)(1,44)

Answer: The answer is super easy bc it is only a small difference. The outcome of (-5)^2 will be 25 meanwhile -5^2 will have an outcome of -25

Answer:

(-5)² = 25      -5² = -25

Step-by-step explanation:

When we have (-5)², then -5 gets multiplied to itself. When there are two negative numbers, the answer is always positive. ex. (-5 x - 5 = 25)

(-5)² = 25

-5 x 5 = -25

-5² = -25

Answer:

1 . 4 hrs , 2 . total 400 miles because the first train had travelled 160 miles and 2nd one had travelled 240 miles

Step-by-step explanation:

in 1. use relative motion concept I. e. you sir on 1st train and put velo. of same mag. and in oppo. direction on the train on which you have sit and do the same with the velocity only with 2nd train means you stop the train on which you are sitting and put the velocity of the train on which you are sitting on 2nd train but in oppo. direction , so now the relative velocity comes out to be 20 mph and then apply formula time = Srel / Vrel and here we can find S rel by multiplying the velo. of 1st train by given time I. e. 2 hrs and in 2. multiply the time calculated by us by the velocity of both trains and by which you get the dist. travelled by both trains and then add them to get final answer.

Answer:

54.25%

Step-by-step explanation:

The percent change is given by:

[tex]p=\frac{final-initial}{initial}[/tex] × [tex]100[/tex]

Plugging all the values,

[tex]p=\frac{94-43}{94}[/tex] × [tex]100[/tex]

[tex]P=54.25%[/tex]%

Therefore, the percent change from 94 to 43 is 54.25%

Answer:

1/10

Step-by-step explanation:

1/5 * 1/2 = 1/10

=============================================================

Explanation:

Let's say that all of the 11 songs are 2 minutes each, which is just a bit under the "2 minute 1 second" mark of the shortest song. I'm going for the lowest time value possible and rounding to the nearest minute.

This would mean the entire album is 2*11 = 22 minutes long. This is the lower bound or the shortest the album can be.

If we go to the other end of the spectrum, and say each song is 6 minutes (I rounded "5 minutes 37 seconds" up to the nearest minute), then the album is now 6*11 = 66 minutes long. This is the upper bound or the longest the album can be.

While we don't know how long the album is exactly, due to the fact we don't know the individual song lengths (other than the shortest and longest songs), we do know 100% that the album length is somewhere between 22 minutes and 66 minutes.

In other words, 22 < x < 66 where x is the album length in minutes.

Of the four answer choices, 44 is the only one that fits, i.e. 22 < 44 < 66.

So I would say 44 minutes is a reasonable estimate. Or better yet, we can rule out 4 minutes, 88 minutes and 10 minutes as they don't fit in the interval 22 < x < 66.

Answer: -8 is the answer.

Step-by-step explanation:

according to the question:

{{(8+4)*5}/(-10)}-2

= {[12*5}/(-10)]-2

= [60/(-10)]-2

= -6-2 = -8

Step-by-step explanation:

8+4=12

12×5=60

60÷-6=-6

-6-2=-8

the correct answer is D. -8

Answer:

They're congruent by Side-Angle-Side (SAS)

Step-by-step explanation:

Midpoint Q makes sides LQ and QN equal, as well as MP and QP, so there's a side, depending on which one you choose.

We're told that angle L = angle N, so there's the equal angle.

Finally, we're told that LM = NP, so there's the other side.

Answer: t = 9

Step-by-step explanation:

Given

-t = 9 (t - 10)

Expand parentheses and apply the distributive property

-t = 9 · t - 9 · 10

-t = 9t - 90

Subtract 9t on both sides

-t - 9t = 9t - 90 - 9t

-10t = -90

Divide -10 on both sides

-10t / -10 = -90 / -10

Step-by-step explanation:

This question asks for us to evaluate: (5/7)³

(5/7)³

- 5/7 x 5/7 x 5/7

= 125/343

There are two ways to list the angles:

1) Simply name them based on the points:

∠W , ∠X , ∠Y , ∠Z

2) The way that I believe that you are supposed to list them in this case. List them as such:

∠WYZ , ∠YZX , ∠ZXW , ∠XWY
