I need help! I don't really understand.... Can someone help for these 2 questions?? Part A and B??

Answer:

2^x-4=4

add 4 to both sides

2^x=8

8 is equal to 2*2*2 or 2^3

2^x=2^3

The bases are now both 2 and you can find x.

Answer:

6n - 5 = c, 6n - 5 + n, 7n - 5

Step-by-step explanation:

Pretty much whatever Nina has, Clayton has 6 times that and minus 5. n = Nina, c = Clayton. 6n - 5 + n should also work if they are asking to add both, which can be simplified to 7n - 5.

Hopefully, this helps since the question is kind of worded to confuse, but the answer I gave should be good.

Answer:

c. 3680

Step-by-step explanation:

In 2010, the population was 8000.

In 2014, it increased by 15%.

Population in 2014 :

= 8000 + 15/100×8000

= 8000 + 1200

= 9200.

Now, 2/5 of the population was age 12 or under.

= 2/5 × 9200

= 2×1840

= 3680

Answer - c) 3680

Answer:

76017.69 mm²

631000 mm³

295045.04 mm³

Step-by-step explanation:

Surface area = bh + 2ls + lb

Since the sides of the triangular prism are equal (equilateral triangle) = 60 mm each

Height = 405 mm

The surface area of triangular = 76017.69 mm

The volume of triangular prism :

1/2 * base * height * length

Volume = 631000 mm³

If amount of chocolate inside = 335954.96 mm3

Empty space =

Volume of triangular prism - amount of chocolate inside

631000 - 335954.96

= 295045.04 mm³

Answer:

5/6

Step-by-step explanation:

This is because when you roll three times, there are 18 possible numbers (six numbers three times). If you want to get less than five each time, that is 5 number x 3 rolls = 15 numbers.

So...You get 15/18 which simplifies to 5/6

Answer:

The angles are called Vertical Angles. And vertical angles are always equal. So,

Answer:

46 in x 28 in = 1288 in^2

Step-by-step explanation:

First you would have to find the height and the width. Then you would have to times the height time width with the height is 28 in and the width is 48 in then you just have to multiply the witch you then turn out with 1288 and you just put the in^2 at the end so your answer is 1288 in^2.

Answer:

Yes,

Step-by-step explanation:

The measures given which are median and interquartile range have no effect on what the maximum value of a certain distribution will be.

In essence, the information given about the samples of fruits and apples do not point to which fruit sample should possess the sample with maximum weight as the information only gives a general description of each distribution. This means that either samples of orange or apple could have the heaviest piece of fruit.

Answer: About 72 feet

The more accurate value is roughly 71.7260397 feet (however, this value isn't fully exact either).

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

Explanation:

Check out the diagram below. It's effectively the same diagram your teacher provided, but I've added points M and N. I've left out any unnecessary lines.

We're told that "(the length of cable from) E to the ground is 35 feet", so this is the red portion of cable that I've marked this as NE = 35, ie segment NE is 35 feet long. We're also told that NF = 40 feet, which is also shown in red.

The blue portions are chords of the circle. We're given one chord as LE = 80 ft, while the other chord JF is what we want to find out.

-----------------

What we need to find is the radius of this circle. Right away, it's not clear what the radius is; however, we can use the chord LE = 80 to help find it.

It turns out that the chord length c is connected to the radius r and central angle theta like so:

c = 2*r*sin(0.5*theta)

where theta must be in radian mode. The central angle subtends the arc that forms the chord in question.

If we started at point L, and counted the number of spaces to get to E while going clockwise, then we can see that there are 5 spaces

Those five spaces could be written as

Or you could mark it as such on the diagram for a visual reference. Overall, the circle has been cut into 12 equal slices. So going from L to E, going clockwise, will have us take up 5/12 of the full circle.

There are 2pi radians in a full circle, meaning the central angle LME is (5/12)*2pi = 5pi/6 radians.

-----------------

Plug theta = 5pi/6 and c = 80 into the formula mentioned. Isolate the radius.

c = 2*r*sin(0.5*theta)

80 = 2*r*sin(0.5*5pi/6)

80 = 2*r*sin(5pi/12)

80 = 2*r*0.9659258

80 = 2*0.9659258*r

80 = 1.9318516r

1.9318516r = 80

r = 80/1.931 8516

r = 41.4110483

The radius is approximate. The radius is in feet. Make sure your calculator is in radian mode.

-----------------

Now that we know the radius, we can determine how long chord JF is.

The central angle for chord JF is angle JMF

If we start at J and go to F, along the shorter path, then we've gone 4 spaces. This is 4/12 = 1/3 of the full circle. So the radian measure of angle JMF is (1/3)*2pi = 2pi/3 radians.

So,

c = 2*r*sin(0.5*theta)

c = 2*41.4110483*sin(0.5*2pi/3)

c = 71.7260397

Chord JF is roughly 71.7260397 feet long.

When rounding to the nearest foot, that's about 72 feet.

Luis Salary is  1800 dollars

Step-by-step explanation:

Ration of Luis´s salary and Andres´s salary is 5:3

[tex]\frac{L}{A} = \frac{5}{3}\\3L -5A = 0[/tex] -- Eq (1)

Let Luis salary be X

Then Andrews salary in July would be A + 720 while Luis salary in July is L

L = A + 720  ---E q (2)

Substituting the values in above equation 1, we get -

[tex]3 ( A +720 ) -5A = 0\\2 A = 720 *3\\A = 1080[/tex]

Luis Salary is

[tex]A + 720 = 1800[/tex]

Answer:

5.33 trays must be sold to cover all costs including labor

Step-by-step explanation:

Party trays, which cost $14.00 to make not including labor, are sold for $35.00. Profit on party trays excluding labour cost = $35 - $14 = $21 Now we will find total labor cost for making party tray for a day Total labor hours * wages per hour* No. of labors = $7 * $8*2 = $112 Therefore to find how many trays must be sold to cover all costs including labor just divide total labour cost for making party tray for a day by profit on party trays excluding labour cost. = $112/$21 = 5.33 It means 5.33 trays must be sold to cover all costs including labor.

Answer:

The correct Answer is 8164964.62715

Step-by-step explanation:

Since the number couldn't be multiplied by by another number by itself it will give a bunch of numbers, that would somewhat try.

Example: 36, Square root of 36 is 6, since 6 times 6 is 36. Easy!

Answer:

15/28 = 53.57%

Step-by-step explanation:

E 1 = select a red marble

E2 = select a red marble

E 1 ∩ E2
