Answer:

376

Step-by-step explanation:

312,336,336,368,384,416,488,624

the middle numbers are 368 and 384

the median is the middle of the middle numbers

to find this number we add up 368 and 384 and divide the answer by 2

368+384=752

752/2=376

Answer:

376

Step-by-step explanation:

1. To find the median you have to first arrange the numbers in numerical order.

2. Count how many numbers you have.

3. Divide by 2. Go to the number in that position and average it with the number in the next highest position to get the median.

So considering you have 8 numbers if you divide 8 ÷ 2 = 4

the 4th number arranged is 368. Now to average 368 and 384. 368+384=752

752 ÷ 2 = 376

Answer:

x= 8 inches

Step-by-step explanation:

you left out the other lengths but since i had this same question once, the other lengths are 12 and 2-

dimensions of the box:

12 in x 2 in x ?

=272 square inches

and we know that there are 6 faces

area=  2 *(12 * 2) + 2 *(2*x) + 2 *(12*x)

area = 272 sq. in.  = 48 + 4x + 24x

272 = 48 + 28x

272 - 48 = 28x

224 = 28x

x = 8 inches

good luck :)

i hope this helps

brainliest would be highly appreciated

have a nice day!

Answer:

= 8p

Step-by-step explanation:

Steps

5/12

Step-by-step explanation:

5/6 of 1/2 is basically 5/6 times 1/12 which is 5/12.

Answer:

Evaluate for x=0.02,y=0.1,z=0.3

(3)(0.02)−(2(0.12)+0.33)

(3)(0.02)−(2(0.12)+0.33)

=0.013

Answer:

14.4 miles

Step-by-step explanation:

Amanda can jog 18 miles in 5 hours.

At the same rate how many miles can Amanda jog in 4 hours=??

solution:

Distance covered by Amanda in 5 hours = 18 miles

Distance covered in  1 hour = 18/5 miles

Distance covered in  1 hour is =3.6

Distance covered in 4 hours = 4*3.6=14.4

Hence Amanda can jog 14.4 miles in 4 hours

Answer:

Both represent a proportional relationship

Step-by-step explanation:

This is because when the independent variable in each table increases, the dependent variable increases as well, making the relationship proportional.

Answer:

Sum of volumes = (16.6 ± 0.03) cm³

Difference of volumes = (3.8 ± 0.03) cm³

Step-by-step explanation:

Solution

V₁ = (10.2 ± 0.02) cm³ and V₂ = (6.4 ± 0.01) cm³.

∆V = ± (∆V₁ + ∆V₂)

= ± (0.02 + 0.01) cm³

= ± 0.03 cm³

V₁ + V₂ = (10.2 + 6.4) cm³ = 16.6 cm³ and

V₁ - V₂ = (10.2 - 6.4) cm³ = 3.8 cm³

Hence, sum of volumes = (16.6 ± 0.03) cm³

and difference of volumes = (3.8 ± 0.03) cm³

Answer:

9/4

Step-by-step explanation:

First multiply denominator by the whole

That is: 4 x 2 = 8

Secondly, whatever answer you got add it to the numerator

That is: 8 + 1 = 9

Lastly, whatever answer you got, take that as the numerator and the denominator remains the same

That is: 9/4

Finally, this is your improper fraction of the number provided!

Answer:

150 ft²

Step-by-step explanation:

Area of trapezoid = ½(a + b)h

Where,

a = 24 ft

b = 24 + 12 = 36 ft

h = √(13² - 12²) = √25 = 5 ft (pythagorean theorem was applied here)

Plug in the values

Area of trapezoid = ½(24 + 36)*5

= ½(60)*5

Area of trapezoid = 150 ft²

Answer: About 10 ft.

Use Pythagorean's Theorem!

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

9 * 9 = 81

3 * 3 = 9

81 + 9 = 90

[tex]\sqrt{90\\}[/tex] = 3[tex]\sqrt{10}[/tex] ≈ 10 ft.

Answer:

0.75 or 3/4 sheet of paper

Answer:

3/4 of each sheet

Step-by-step explanation:

You have to divide the number of sheets of paper by the number of people sharing them, which gives you 3/4. This makes sense because if there are more people than paper, each person will get less than a full sheet.

Answer:

1. 160cm²

2. 176.25cm²

3. 33.75ft²

Step-by-step explanation:

Area triangle = (1/2)(base)(height)

1)

total area = 2(area small triangle) + 2(area big triangle)

= 2(0.5(8)(9))+2(0.5(8)(11))

=72+88=160cm²

2)

total area = 2(area small triangle) + 2(area big triangle)

= 2(0.5(7.5)(7.5))+2(0.5(7.5)(16))

= 56.25 + 120 = 176.25cm²

3)

total area = 2(area small triangle) + 2(area big triangle)

= 2(0.5(4.5)(2.5))+2(0.5(4.5)(5))

= 11.25+22.5 = 33.75ft²
