Answer:

[tex]225 {m}^{3} [/tex]

Step-by-step explanation:

To find the volume of the shape first we have to split the shape into two rectangles; a large one at the bottom and a small one at the top. The formula to find volume of a rectangle is

[tex]v = length \times width \times height[/tex]

note that after both volumes are found they should be added to determine the volume of the entire shape*

The length of the large rectangle is 5m, the width is 7m, and the height is 6m. Therefore the volume is

[tex]v = l \times w \times h \\ v = 5 \times 7 \times 6 \\ v = 210 {m}^{3} [/tex]

The length of the small rectangle is 5m, the width is 3m, and the height is 1m. Therefore the volume is

[tex]v = l \times w \times h \\ v = 5 \times 3 \times 1 \\ v = 15 {m}^{3} [/tex]

[tex]210 {m}^{3} + 15 {m}^{3} = 225 {m}^{3} \\ therefore \: the \: volume \: of \: the \: \\ entire \: shape \: is: \\ 225 {m}^{3} [/tex]

Answer:

[tex]V_{\ total}=225\ m^3[/tex]

Step-by-step explanation:

Step 1:  Find the volume of the big box

[tex]V_{\ big} = l * w * h[/tex]

[tex]V_{\ big} = 7\ m * 5\ m * 6\ m[/tex]

[tex]V_{\ big} = 210\ m^3[/tex]

Step 2:  Find the volume of the small box

[tex]V_{\ small} = l * w * h[/tex]

[tex]V_{\ small} = 3\ m * 5\ m * (7\ m - 6\ m)[/tex]

[tex]V_{\ small} = 3\ m * 5\ m * 1\ m[/tex]

[tex]V_{\ small} = 15\ m^3[/tex]

Step 3:  Combine the volumes

[tex]V_{\ total}=V_{\ big} + V_{\ small}[/tex]

[tex]V_{\ total}=210\ m^3 + 15\ m^3[/tex]

[tex]V_{\ total}=225\ m^3[/tex]

Answer: [tex]V_{\ total}=225\ m^3[/tex]

Count how many there are per meat mixed with all three different veggies, sounds weird in writing but makes sense if clarified by speech. anyways hope this helped have a great night!

1) Correct option is C)

A fair coin is tossed 100 times and the head occurs 58 times and tail 42 times.

The experimental probability of getting a head is :

P(E)=

Total outcomes divided  by Number of head

58/100 = 29/50 (29/50x100) = 58% (C)

2) 19%​

​

Answer:

1. 42%

2. 33%

Step-by-step explanation:

1. Relative frequency = Number of successful trials ÷ Total number of trials

plug the numbers in and we get 42/100. 42/100 = 0.42 = 42%

2. Experimental probability = Number of in which the outcome occurs ÷ Total number of trials

plug the numbers in and we get 2/6 = 1/3 = 33%

Answer:

D

Step-by-step explanation:

4 times 40 is 160 and 3189 divided by 160 is 19.93

have a great day

Step-by-step explanation:

The semi-perimeter is:

s = (a + b + c) / 2

= (10 + 24 + 26) / 2

= 47

We will find the area of the triangle using the Heron's formula.

A = √[s (s - a) (s - b) (s - c)]

= √[47 (47 - 10) (47- 24) (47 - 26)]

= √10 × 37 × 23 × 21

= √ 56513

Answer:

The answer is 148.6666667

Step-by-step explanation:

1) Set a linear quation

[tex] \frac{22.30}{x} = \frac{15}{100} [/tex]

2) Cross multiply

[tex]15x = 22.30 \times 100[/tex]

3) Multiple the right side

[tex]15x = 2230[/tex]

4) Divide both side by 15

[tex] \frac{15x}{15} = \frac{2230}{15} [/tex]

5) Solve the linear equation

[tex]x = 148.6666667[/tex]

$180

Step-by-step explanation:

Just calculate the perimeter...

4 yards = 12 feet

And add everything up-

18+10+(18-10)+12+12

=60 feet

60 x 3 =180

There you go

Answer:

Yes,

Step-by-step explanation:

16/22 = 0.72727272727

24/33 = 0.72727272727

When translated into decimals, they both equal 0.72 reoccurring.

x = 0.72727272727...

10x = 7.2727272...

100x = 72.727272727...

100x - x = 90x = [tex]\frac{72}{90}[/tex] which can be translated/simplified into [tex]\frac{16}{22}[/tex] and [tex]\frac{24}{33}[/tex]

Answer:

Graph 3

Step-by-step explanation:

equation: y = mx + b → y = 1/3x - 4

- m is the slope (slope = rise / run):

- b is the y intercept (when x = 0): -4

Graph 1 is incorrect because the y-intercept is 1.5 on this graph when the equation is -4

Graph 2 is incorrect because the slope is 3 / 1, the rise is 3 and the run is 1

the correct equation for this graph is y = 3x - 4

Graph 3 is correct because the slope is 1/3, the rise is 1 and the run is 3

and the y intercept is -4

Graph 4 is incorrect because the y-intercept is not even shown

Answer:

(9 - 5)^3 = ?

or

9^3 - 5^3 = ?

Answer:

64

Step-by-step explanation:

The computation inside the parentheses must be done first according to Order of Operations rules:

(3² - 5)³  =  (9 - 5)³  =  4³  =  64

Answer:

48 inches.

Step-by-step explanation:

The triangle is an isoscele triangle.

An isosceles triangle is a triangle with two sides of the same length.

h is opposite of the other side of 48 inches and judging by the picture, it looks exactly the same, therefore the answer is 48 inches.

Answer:

48 inches

the guy a bouve me is right

Answer: The answers are in the screenshots

Step-by-step explanation:

For the first one you have to find the points first then multiply each of the points by 2 because it is dilated by 2, then you will get the answers of the two windows.

For the second one you have to -10 for the y axis, then you will have to make all the x values negative, then you will get the points for the door. (I did not do the doorknob, you can try doing it)

If you need help search the formula for dilation, translation, reflection and more.

Hope this helps

Answer:

B.) 36/60

Step-by-step explanation:

some

equivalent fractions of 9/15:

3/5 = 6/10 = 9/15 = 12/20 = 15/25 = 18/30 = 21/35 = 24/40 = 27/45 = 30/50 = 33/55 = 36/60

Answer:

36/60

Step-by-step explanation:

Either Cross Multiply or Turn into decimal to find the following answer.

For this question I suggest to turn into decimal.

Cross multiply would take longer time, but if you wish you could use both ways to check your answer.

I will be turn into decimal:

Main Fraction: 9/15 ⇒ 0.6

3/10 ⇒ 0.3

36/60 ⇒ 0.6

27/35 ⇒ 0.77142857142

20/30 ⇒ 0.66666666666

As you can see out of all the fractions:

36/60 is equal to 9/15

Answer: feet: 1, 2, 3, 4, 5

          inches: 12, 24, 36, 48, 60

Step-by-step explanation:

There are 12 inches in a foot, therefore if you have 1 foot you have 12 inches, if you have 2 feet you have 24 inches becauase 2*12 = 24 and so on...
