A box has dimensions 6in x 3in x 7in. What is the volume?

Answer:

x=28

m<ACD=68°

Step-by-step explanation:

2x+(180-124)+(180-4x)=180

-2x+236=180

-2x=180-236

-2x=-56

x=28

m<ACD=180-4x=180-4(28)=180-112=68

Answer:

The answer is <ACD = 68°

Step-by-step explanation:

Using the property that the sum of interior angles in a triangle is equal 180°,we have:

<DAC + <ACD + <ADC = 180°

[tex]2x + (180 - 4x) + 56 = 180 \\ - 2x + 56 = 0 \\ 2x = 56 \\ x = \frac{56}{2 } \\ x = 28[/tex]

Finally, calculating the angle <ACD, we have:

<ACD = 180 - 4x

<ACD = 180 - 4 . 28

<ACD = 180 - 112

ACD = 68°

Answer:

no

Step-by-step explanation:

4(3a-3)+2a when you expand youget

((4x3a)-(4x3)) + 2a = 12a - 12 + 2a then we collect the like term first 12a + 2a - 12

14a -12

therefore 14a - 12 is not equal to 14a- 3

Answer:

Domain is all real numbers.

Step-by-step explanation:

Domain is the x-values, as you see the function goes on forever on the x-axis because of the arrows.

Answer:

25 + 14

Step-by-step explanation:

Sum means addition of values.

Answer:

25+14

Step-by-step explanation:

expression doesn’t use an equal sign and sum is addition :)

Answer:

x<−1

Step-by-step explanation:

Answer:

x < -1

2(3x - 4) + 14 > -2(-3x - 5) + 4x

<=> 6x - 8 + 14 > 2(3x + 5) + 4x

<=> 6x + 6 > 6x + 10 + 4x

<=> 4x + 4 < 0

<=> 4x < -4

<=> x < -1

Answer:

115 m

Step-by-step explanation:

Answer:

[tex]\boxed{\textsf {The given polynomial is a quadratic polynomial. }}[/tex]

Step-by-step explanation:

A polynomial is given to us and we need to make the polynomial by its degree . Here the given polynomial is 3x² + 5x -3 .

[tex]\sf\implies p(x)= 3x^2+5x-3 [/tex]

So here we can see that the highest power of the variable in the given polynomial is 2 . So the polynomial is a quadratic polynomial .

★ More to Know :-

When we equate this quadratic polynomial with 0 , it becomes a quadratic equation.

That is ,

[tex]\sf\implies p(x)= 3x^2+5x-3=0[/tex]

This is done in order to find the zeroes of the polynomial. The zeroes of the polynomial are the values for which the polynomial becomes 0 .

Answer:

h = [tex]\frac{3v}{\pi r^{2} }[/tex]

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

Answer:

30

Step-by-step explanation:

The angle for BOF is going to be 180.

So if the angle for COF is 150, then COB is going to be the complement angle.

This means it's 180 - 150 = 30.

Answer: 4f^2 -4f+1

Step-by-step explanation:

2f-1)^2

This is equal to

(2f-1) * (2f-1)

FOIL

first: 2f*2f = 4f^2

outer: 2f*-1 = -2f

inner: -1*2f = -2f

Last = -1*-1 = 1

Add them together: = 4f^2 -2f-2f+1

Combine like terms 4f^2 -4f+1

Answer:

(2f-1)(2f-1)

2f^2-2f-2f+1

2f^2-4f+1

Answer:

12.5

Step-by-step explanation:

37.50÷15=2.5

2.5×5=12.5

Answer: $12.50

Step-by-step explanation:

You have to divide 37.5 by 15 which is 2.5 then multiply that by 5 which is 12.5.

Answer:

7

Step-by-step explanation:

well let’s just think that there’s already 10. let’s ignore the 10 for later.

now let’s think about 6x. of course the x is unknown (variable) which we have to find, so what you want to do, (easy way) think of every multiple of the number 6. so that of course includes 6, 12, 18... etc. now if you continue, you will get to the number 42. now it might not click right there but 42... is what we need since we already have the 10. since 42 + 10 = 52, now we just need to find out what 42 divided by 6 is... 7! 7x6 or 7(6) is 42, plus the starting 10 is 52!

therefore, x = 7.

Answer:

The time it will take is 8hours 45mins.

Step-by-step explanation:

Since y = –240x represents a submarine descent. We are looking for how long, that is the time, it will take for the submarine to make a descent of 2100. We know that y is the elevation, if it is descending it will be in the negative direction, making it -ve.

A descent of 2100 means y = –2100. Hence,

–2100 = –240x

x = –2100/–240 = 8.75hours = 8hours 45minutes. (0.75hours = 3/4hours = 3/4 x 60mins = 45mins).
