Answer:

9.4.6=216

216.1,3=280

Step-by-step explanation:

[tex] \huge\hookrightarrow \mathbb{ \color{gold}Answer}[/tex]

We know,

[tex] \boxed{volume = l \times b \times h}[/tex]

so,

[tex]\hookrightarrow{volume = 6 \times 4 \times 9}[/tex]

[tex]\hookrightarrow volume = 216 \: m {}^{3} [/tex]

now,

[tex] \boxed{density = \frac{mass}{volume} }[/tex]

So,

[tex] \hookrightarrow1.3 = \dfrac{m}{216} [/tex]

[tex]\hookrightarrow \: m = 216 \times 1.3[/tex]

[tex] \hookrightarrow \: m = 280.8[/tex]

hence, mass of air in the room is 280.8 kg

Answer:

u ≈ 11

Step-by-step explanation:

10² = u² - 2(5)(2)

100 = u² - 20

120 = u²

u = [tex]\sqrt{120}[/tex]

u = [tex]\sqrt{4}[/tex][tex]\sqrt{30}[/tex] = 2[tex]\sqrt{30}[/tex] which is 10.95

Answer:

163 pounds

Step-by-step explanation:

you would use 145 and add 12 to it for the first month, then add 6 for the next month, which will give you a new weight of 163 pounds

Answer:

Sue travels for 3 hours and a half

Sue stays stationary for 2 hours and a half

Step-by-step explanation:

Everytime the curve climbs, it means Sue is travelling. Everytime the curve stays flat, it means Sue is stays stationary. It remains to count up the total for both categories, with one square being 30 minutes.

Sue spends 3.5 hours on travelling and 2.5 hours stationary.

It is a graph which shows how far an object has travelled in a given time.

It is graph of function which represents there is no change in the function value or the function value is constant.

"subtract old value from new value."

For given example,

Given distance-time graph represents a journey made by Sue.

Let 't' represents the travelling time and 's' represents the stationary time.

If we observe the graph,

from 2 pm to 3 pm Sue travelled 5 miles

⇒ t1 = 3 - 2

⇒ t1 = 1 hour

from 3.5 pm to 4 pm she travelled 10 miles

⇒ t2 = 4 - 3.5

⇒ t2 = 0.5 hour

from 5 pm to 6.5 pm she travelled 15 miles

⇒ t3 = 6.5 - 5

⇒ t3 = 1.5 hours

from 7.5 pm to 8 pm she travelled 5 miles

⇒ t4 = 8 - 7.5

⇒ t4 = 0.5 hour

So, the total travelling time would be,

⇒ t = t1 + t2 + t3 + t4

⇒ t = 1 + 0.5 + 1.5 + 0.5

⇒ t = 3.5 hours

Also, Sue spends stationary from 3 pm to 3.5 pm

⇒ s1 = 3.5 - 3

⇒ s1 = 0.5 hour

She spends stationary from 4 pm to 5  pm

⇒ s2 = 5 - 4

⇒ s2 = 1 hour

She spends stationary from 6.5 pm to 7.5 pm

⇒ s3 = 7.5 - 6.5

⇒ s3 = 1 hour

So, the total stationary time would be,

⇒ s = s1 + s2 + s3

⇒ s = 0.5 + 1 + 1

⇒ s = 2.5 hours

Therefore, Sue spends 3.5 hours on travelling and 2.5 hours stationary.

Given:

The vertical height of the trapezoid = 2.9 m

The bases of the trapezoid are 2.3 m and 9.3 m.

To find:

The area of the given trapezoid.

Solution:

The area of a trapezoid is:

[tex]A=\dfrac{1}{2}(a+b)h[/tex]

Where, a, b are bases or length of parallel sides and h is the vertical height of the trapezoid.

Putting [tex]a=2.3,\ b=9.3,\ h=2.9[/tex] in the above formula, we get

[tex]A=\dfrac{1}{2}(2.3+9.3)(2.9)[/tex]

[tex]A=\dfrac{1}{2}(11.6)(2.9)[/tex]

[tex]A=16.82[/tex]

Therefore, the area of the given trapezoid is 16.82 square m.

Answer:

y = 3/4x + 5

Step-by-step explanation:

Slope intercept form is represented by the formula y = mx + b where m is the slope and b is the y-intercept. You were given the slope, but to write the equation, you also need the y-intercept.

First, plot the point they gave you (-8, -1) on a graph. Then use the rise over run of the slope (rise 3 and run 4) to find the next points until x = 0 (where the line crosses the y-axis). As you can see in the image, I plotted the points. 5 is the y-intercept because it is the y value on the line when x = 0.

So with the slope 3/4 and the y-intercept of 5, you can substitute the values and get your equation:

y = mx + b

y = (3/4)x + (5)

y = 3/4x + 5

Answer:       ≈ 0.6181

Step-by-step explanation:

The probability that at least 2 boys choose the same type of watch is 0.6181.

Probability has been introduced in Maths to predict how likely events are to happen. The meaning of probability is basically the extent to which something is likely to happen.

Here, the total number of combinations of styles for 5 boys

   12 X 12 X 12 X 12 X 12 = 12⁵

the total ways that each boy have different styles

   12 X 11 X 10 X 9 X 8

P(None of the boys have same style) = (12 X 11 X 10 X 9 X 8) / 12⁵

                                                                = 0.3819

P(at least 2 boys have same style) = 1 - P(None of the boys have same style)

                                                         = 1 - 0.3819

                                                         = 0.6181

Thus, the probability that at least 2 boys choose the same type of watch is 0.6181.

Step-by-step explanation:

when you find the median you split the numbers in half from the upper to lower parts of the data. then you find the median of the upper part and that is the upper quartile.

median: 32

32, 36, 37, 40, 42, 45, 50

add 40+42 then divide by 2 and you get 41

Answer:

X:6.7

Y:17

Z:33

Step-by-step explanation:

Because their similar to each other, the corresponding angles are equal.

5y-3=82

5y=85

y=17

Angle J=angle M=z=180-82-65=33

3x-2=18.1

3x=20.1

x=6.7

Answer:

x = 6.7

y = 17

z = 33°

Step-by-step explanation:

To find x:

Because IJK≅LMN, you know that 3x-2 = 18.1

3x-2 = 18.1

Add 2 to both sides:

3x-2+2 = 18.1+2

3x = 20.1

Divide both sides by 3:

3x/3 = 20.1/3

x = 6.7

To find y:

5y-3 = 82

Add 3 to both sides:

5y-3+3 = 82+3

5y = 85

Divide both sides by 5:

5y/5 = 85/5

y = 17

To find z:

Because all triangles angles must add up to 180, find 180-82-65:

180-82-65 = 33 degrees

Because IJK≅LMN, z = 33 degrees

Complete Question

Consider greenhouse A with floor dimensions w = 16 feet , l = 18 feet.

A concrete slab 4 inches deep will be poured for the floor of greenhouse A. How many cubic feet of concrete are needed for the floor?

Answer:

96 cubic feet

Step-by-step explanation:

The volume of the floor of the green house = Length × Width × Height

We convert the dimensions in feet to inches

1 foot = 12 inches

For width

1 foot = 12 inches

16 feet = x

Cross Multiply

x = 16 × 12 inches

x = 192 inches

For length

1 foot = 12 inches

18 feet = x

Cross Multiply

x = 18 × 12 inches

x = 216 inches

The height or depth = 4 inches deep

Hence,

Volume = 192 inches × 216 inches × 4 inches

= 165888 cubic inches

From cubic inches to cubic feet

1 cubic inches = 0.000578704 cubic foot

165888 cubic inches = x

Cross Multiply

x = 16588 × 0.000578704 cubic foot

x = 96 cubic feet

Therefore, 96 cubic feet of concrete is needed for the floor
