Answer:

12 ft^3

Step-by-step explanation:

Given data

Dimension

Lenght= 2ft

Width= 3ft

Height= 2ft

The expression for the volume is

Volume= L*W*H

Substitute

V= 2*3*2

V= 12 ft^3

Hence the volume of the box is 12 ft^3

Here's the solution,

figure 1.

by using trigonometry,

=》

[tex] \sin(60) = \dfrac{5 \sqrt{3} }{y} [/tex]

=》

[tex] \dfrac{ \sqrt{3} }{2} = \dfrac{5 \sqrt{3} }{y} [/tex]

=》

[tex] \dfrac{1}{y} = \dfrac{ \sqrt{3} }{2 \times 5 \sqrt{3} } [/tex]

=》

[tex] \dfrac{1}{y} = \dfrac{1}{10} [/tex]

=》

[tex]y = 10[/tex]

And,

=》

[tex] \cos(60) = \dfrac{w}{y} [/tex]

=》

[tex] \dfrac{1}{2} = \dfrac{w}{10} [/tex]

=》

[tex]w = 5[/tex]

So, values are :

figure 2.

Since, it's an isosceles triangle, w = y,

So, by pythagoras theorem :

=》

[tex] {w}^{2} + {y}^{2} = (7 \sqrt{2} ) {}^{2} [/tex]

=》

[tex] {w}^{2} + {w}^{2} = 98[/tex]

=》

[tex]2 {w}^{2} = 98[/tex]

=》

[tex] {w}^{2} = 49[/tex]

=》

[tex]w = \sqrt{49} [/tex]

=》

[tex]w = 7[/tex]

and we know, w = y, so their values will be equal to 7 units.

Answer:40 miles per hour

Step-by-step explanation:

This is because, If 20 miles is 1/2 of his drive home then 40 miles should be the rest. Multiply 20 by 2 since it is 1/2

Answer:

m puq

Step-by-step explanation:

Answer:

I don’t know but I know 27 times 630 plus 19 times 680 is 29,930 I’ve tried some other ways but it gets really close but not exact

Step-by-step explanation:

Answer:

Step-by-step explanation:

A = 3M

J = 2A

J = 6M

Marie = M

Andre = 3M

Jane = 6M

6M+3M+M = 840

10M = 840

M= 84 Pounds

Andre = 3M

Andre = 84*3

Andre has 252 pounds of apples.

Answer:

Step-by-step explanation:

a + c = 1000

9a + 5c = 6680

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

9a + 9c = 9000

9a+ 5c = 6680

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

4c         = 2320

c           = 580

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

a+ 580 = 1000

a = 420

A = 420

C = 580

If you substitute the numbers into 9a + 5c = 6680, that should give you the right answer.

Answer:

6000

Step-by-step explanation:

so you have to divide 3000 and 6 to get 500

next you would do  500 times 6 equals = 3000

so now you would plus them and get 6000

now that is your answer

Answer:

75 degrees

Step-by-step explanation:

Complementary angles equal 90 degrees together. That is the case with angle X and Y. Set an equation to describe the situation.

Y=1/5X

X=5Y

Now, set another equation:

X+Y=90

Substitute the first equation into the second one.

5Y+Y=90

6Y=90

Y=15

Substitute this once again:

X+15=90

X=75

Answer:

-0.25

Step-by-step explanation:

count how many tick marks are between each number. Since there are four tick marks it is divided by fourths.

f(x) = 3x + 1

f(9) = 3(9) + 1

f(9) = 27 + 1

f(9) = 28

f(9) = 28. I hope this helps! I have a g00gle classroom where I help with algebra including this. If you are interested, please consider joining. I will post the class code in the comments if it would let me. Sorry it wouln't let me type g0ogle properly.

Answer:

28

Step-by-step explanation:

f(9) means when x = 9.

when x = 9,

f(9) = 3(9) + 1

= 27 + 1

= 28

Answer: For Mrs. Bhan, she pay 9.75 each visit for ten time so 10 ÷ 97.50

I don’t know how to answer for Mr. Stewart but I answer Mrs. Bhan. Hope this helps!

Answer:

Step-by-step explanation:

a)

eq 1) 97.50 = fee + 10x

eq 2) 83.50=fee +8x

subtract eq 2 from eq 1

14 = 2x

7 =x

each visit costs $7

b)

97.50 = fee + 10(7)

97.5- = fee +70

27.5 = fee

it costs $27.50 to sign up at the gym

( this seems like an expensive gym )

c)

gym costs = 27.50 + 7 per visit

cost = 27.50 +7x

( let's look for a less expensive gym :D  )

Answer:

any number between 83 and 0. [tex]0\leq x\leq 83[/tex]

Step-by-step explanation:

the number 1,548.4484 has the last two digits of 84.

And since the number has to be less than the other number and you can only switch the last two digits in the decimal's place. It has to be less than 84

Hope that helps :)

Answer:

the digit is 4, because that has 4484 but just put 4444

Answer:

there is a cluster from 1-4

there is a gap from 5-7

The spread is from 1-8

Step-by-step explanation:

These are all true if you look... there is a bunch from 1-4, there is none from 5-7, and all of them are within 1-8, but  the highest amount isn't at 3.

Answer:

m=1/2 & b=-2

Step-by-step explanation:

so in order to find m & b we need to distribute 1/2

y=1/2(x+6)-5

y=1/2x+3-5

y=1/2x-2

y=mx+b so

m=1/2 & b=-2

Answer: i dont know where u got m and b from but y=[tex]\frac{x}{2}[/tex] abd x= 2y+4 :)

Answer:

a. the error is that he wrote 0.05 instead of 0.2

0.148835 ≈ 0.2

b.

0.2 = 2 × 0.1

0.2 = 2 × 10⁻¹

The mass is about 2 × 10⁻¹ kg

Answer:# of cars: 1 | 0 | 0 | 0 | 2 | 4 | 5 | 3 | 0 | 2 | 2 | 1 |

Note: the answers are from left to right in order

Step-by-step explanation:

So this isn't as hard as it seems. You just count the X's and if there is like for example 1 x on 30 then the answer for 30 is 1 since there is only 1 X.

Answer:

x = 136°

Step-by-step explanation:

The opposite angles of a cyclic quadrilateral are supplementary, that is

x + 44° = 180° (subtract 44° from both sides )

x = 136°
