write the formula for the surface area of a rectangular prism​

Answer:

A) 29 plants

B) $90.75

Step-by-step explanation:

A) Divide 79.75 by 2.75. It will give you the plant number.

B) Multiply 4 and 2.75 which should equal 11. Add that to 79.75.

Good Luck!!!!!!!

[tex] \bullet [/tex] Radius (r) of the cone is 3 ft.

[tex] \bullet [/tex] Height (h) of the cone is 9 ft.

The volume of the cone.

We know,

Formula of Volume of cone is [tex] \frac{1}{3} [/tex]πr²h

So, Volume of the cone = [tex] \frac{1}{3} [/tex] × [tex] \frac{22}{7} [/tex] × (3)² × 9

Volume of the cone = [tex] \frac{1}{3} [/tex] × [tex] \frac{22}{7} [/tex] × 3 × 3 × 9

Volume of the cone = [tex] \frac{22 \: × \: 3 \: × \: 3 \: × \: 9}{3 \: × \: 7} [/tex]

Volume of the cone = [tex] \frac{1782}{21} [/tex]

Volume of the cone = 84.86 cubic ft.

Answer:

B) 1153000

Step-by-step explanation:

Given

See attachment

Required

Number of households without computer in 2009

From the attachment, we have:

[tex]n=5170000[/tex] --- survey

[tex]p = 22.3\%[/tex] --- proportion without computer

So, the actual number is:

[tex]Number = p * n[/tex]

[tex]Number = 22.3\% * 5170000[/tex]

[tex]Number = 1152910[/tex]

[tex]Number \approx 1153000[/tex]

Hence: (B) is correct

Answer:

All of them except the second one and third one are true .

Answer:

1/3, 3, -1/3

Step-by-step explanation:

A rational number is a number that can be expressed with a fraction. In this case we have:

1/3 , 3 (all natural numbers are also rational: in fact for example 3 can be expressed with the fraction: 3/1) , -1/3

333/0 is not a rational number because the division is impossible

√3 is not rational because can’t be expressed with a fraction

Answer:

$2,825.00

Step-by-step explanation:

First, I found out what 6.5% of 2,500 is, so 6.5% x 2,500 = 162.5 . Then I did 162.5 x 2, which equals 325. I then added 325 to 2,500 and got 2,825.

Answer:

range = 13

median = 23

mode = none

mean = 22

Step-by-step explanation:

Answer:

mean: 22

median: 23

mode: none

range: 13

Step-by-step explanation:

mean

the mean of a data set is the sum of all the terms divided by how many terms there is, so:

23 + 29 + 25 + 16 + 17 ÷ 5 = 22

median

the median of a data set is the middle number so we arrange in order:

16, 17,  23, 25, 29

23 is the middle, so that's the median

mode

the mode is the number that's repeated the most, there isn't any repeats, so there isn't a mode

range

The range is the lowest value (16) subtracted from the highest value (29)

29 - 16 - 13

hope this helps:)

Answer:

Explanation:

according to the coordinates the triangles is right at the pair (2, -3)

the area of the triangle = height × base × 1/2

the height is the line passing through the pairs (-1, 6) and (2, -3)

h² = (2-(-1))²+(-3-6)²

h² = 3² + (-9)²

h² = 9 + 81

h² = 90

h = √90

the base is the line passing through the pairs (5, -2) and (2, -3)

b² = (2-5)²+(-3-(-2))²

b² = 3² + (-3+2)²

b² = 9 + 1

b² = 10

b = √10

A = h×b×1/2

A = √90×√10×1/2

A = √900×1/2

A = 30×1/2

A = 15 u²

Answer:

A

Step-by-step explanation:

The Pythagorean theorem only works for right triangles. A right triangle has one 90-deg angle. This triangle has no 90-deg angle, so it is not a right triangle, and the Pythagorean theorem does not work to solve it.

Answer: A

Answer:

26°

Step-by-step explanation:

The angle 123° is on a straight line. All angles on a straight line add up to 180°, so the first thing you should do is subtract 123 from 180.

(180-123)

Now, your answer should be 57°, and that is equal to angle W.

You now know two angles. Angles in a triangle add up to 180°, too, so all you do now is the following:

97 + 57 = 154

180- 154 + 26

And there's your answer!

Answer:

x=4

y=7

Step-by-step explanation:

x=4 because the left and right sides are equal

the upper side should equal the bottom side

so y+5=12

y=12-5

y=7

Answer:

C.

Step-by-step explanation:

If you think about it, it makes a little bit of sense. You pay $3.99 for the bag of cookies when the initial price was $4. To you, it sounds cheaper. But you're technically paying the same amount of cash as you would for the previous amount of cookies, as nobody in America keeps 99 cents in their pockets at all times, and 99 cents obviously rounds up to a dollar, so it's technically the same price as before. Overall, this would be essentially just a cheap marketing technique that they're using to get more money out of a larger group of people. If they're trying to get rid of old cookies, they wouldn't lower the price by just a cent, lowering the price by just a cent in order to improve the reviews might as well do the opposite, and paying an extra cent doesn't make much of a difference considering the old price.  So thus the answer is C.

Have a good rest of your day.

Answer:

the measure of <ABD = 1/2 the measure of <ABC is the answer :)

Step-by-step explanation:

Answer:

V = 4800 cm^3

SA = 2000 cm^2

Step-by-step explanation:

V = l x w x h

V = 20 x 8 x 30

V = 4800 cm^3

20 x 8 x 2 = 320 cm^2

20 x 30 x 2 = 1200 cm^2

8 x 30 x 2 = 480 cm^2

320 + 1200 + 480 = 2000 cm^2

Answer: 5 outfits

Step-by-step explanation: 17.63x2=35.26

                                             437.63+35.26+18.11=491

                                              680-491=189

                                              189 divided by 35.19= 5 (rounded)

Answer:

40

Step-by-step explanation:

1. Plug in the given value for n

6(5) + (5)2

2. Solve using PEMDAS

(I'm not sure if the 2 after the n is supposed to be squared, but if it was n^2 then the correct answer would be 55, I think)

30 + 10 = 40

Therefore, the answer is 40

Hope this helps :)

Answer:

The length of the side JH is approximately 31.5 feet long.

Step-by-step explanation:

There is a trigonometry law called the law of sines, which states the sine of an angle divided by its opposite side is equivalent to the sine of all the other angles in that right triangle divided by its corresponding opposite side. You can use this law to help you solve for x. By applying the law of sines, you'll get that [tex]\frac{sin(90^{o})}{88} =\frac{sin(21^{o})}{x}[/tex] ⇒ [tex]\frac{88}{sin(90^{o})} =\frac{x}{sin(21^{o})}[/tex] ⇒ [tex]x = \frac{88*sin(21^{o})}{sin(90^o)}[/tex] ⇒ [tex]x=31.5ft.[/tex]
