Answer:

A=384

Step-by-step explanation:

For this case we have by definition, that the surface area of a cube is given by:

[tex]SA = 6l ^ 2[/tex]

Where:

l: It's the side of the cube

We have as data, according to the figure, that:

[tex]l = 8ft[/tex]

Substituting in the figure:

[tex]SA = 6 (8) ^ 2\\SA = 6 * 64\\SA = 384 \ ft ^ 2[/tex]

Thus, the surface area of the cube is [tex]384 \ ft ^ 2[/tex]

Answer:

[tex]384 \ ft ^ 2[/tex]

Answer:

B) 4, 8, 10

Step-by-step explanation:

4+8 is greater than 10

4+10 is greater than 8

10+8 is greater than 4

Part A

w = width

L = length

L = w+8 since the length is 8 mm longer than the width

====================================================

Part B

P = perimeter of rectangle

P = 2*(L+W) = 2L + 2W

We want the perimeter to be more than 32 mm, so we want P to be greater than 32

This means we write P > 32

Replace P with either 2(L+W) or 2L+2W. I'll pick 2L+2W

So we go from

P > 32

to

2L+2W > 32

After this, replace L with W+8 (refer to part A above)

We now have

2(W+8) + 2W > 32

====================================================

Part C

Let's solve the inequality found in part B to get...

2(w+8) + 2w > 32

2w + 16 + 2w > 32

4w + 16 > 32

4w + 16-16 > 32-16 ....... subtracting 16 from both sides

4w > 16

4w/4 > 16/4 ......... dividing both sides by 4

w > 4

Answer:

[tex]y = 3x + 5[/tex]

Step-by-step explanation:

First, find the rate of change [slope]:

-y₁ + y₂\-x₁ + x₂ = m

[tex]\frac{-11 + 17}{-2 + 4} = \frac{6}{2} = 3[/tex]

Now, plug the coordinates into the Slope-Intercept Formula instead of the Point-Slope Formula because you get it done much swiftly. It does not matter which ordered pair you choose:

[tex]y = 3x + 5[/tex]

Answer:

The worth of one bill is $20 and the worth of the other bill is $1

Step-by-step explanation:

Let

x----> the worth of one bill

y ---> the worth of the other bill

I assume x > y

we know that

x+y=21 ----> equation A

x=y+19 ---> equation B

Solve the system by elimination

Multiply equation B by -1 both sides

-x=-y-19 ----> equation C

Adds equation A and equation C

x+y=21

-x=-y-19

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

y=21-y-19

2y=2

y=1

Find the value of x

x=y+19 -----> x=1+19=20

therefore

The worth of one bill is $20 and the worth of the other bill is $1

Answer:

C=K-273.15

Step-by-step explanation:

Here we are given the relation between the measurements of temperatures in Celsius C and Kelvin K . The relationship is as under

K=C+273.15

now we have to rewrite this equation so that we can evaluate C in terms of K

In  order to do so , we Subtract 273.15 from both sides.

K-273.15 = C + 273.15-273.15

K - 273.15=C

C=K-273.15

Answer:

A) The rate of change of the cost of parking in the lot is $3.00 per  hour

Step-by-step explanation:

for y=mx+b:

b is the base "cost" ($4)

x is the number of hours parked in the parking lot

m is the slope or how much it costs to be parked PER hour

therefore, for x hours, the cost would be 3*#of hours + $4, so the rate of change of the cost of parking in the lot is $3 per hour (which is shown by m or the slope)

Answer:

Option A

Step-by-step explanation:

we have

x -----> is the number of hours

c(x) ----> is the cost for parking in a city lot

we know that

c(x)=3x+4.00

This is a linear equation in slope intercept form

where

the rate of change or slope m is equal to m=$3 per hour

the y-intercept is equal to b=$4.00 (this is the cost when the number of hours is equal to zero)

therefore

The rate of change of the cost of parking in the lot is $3.00 per

hour

Answer:

k=-5 or k= -13

Step-by-step explanation:

lk+9l=4

k+9=4 or k+9=-4

k=-5 or k= -13

The solutions for the equation |k+9| = 4 are k = -5 and k = -13. We got these results by considering separately the positive and negative cases for the absolute value.

To find the solution to the equation |k+9| = 4, we need to think about what the absolute value operation represents. Absolute value takes the positive version of whatever is inside, no matter if it's positive or negative. So we actually need to consider two separate cases.

So the solutions to the equation are k = -5 and k = -13.

Answer:

{[tex](x,y)|(x=3,y=4)[/tex]}

Step-by-step explanation:

The given system of equations is;

[tex]y-4=0...(1)[/tex]

and

[tex]2x-y-2=0...(2)[/tex]

We rewrite the equations in the standard form to get:

[tex]y=4...(3)[/tex]

[tex]2x-y=2...(4)[/tex]

We now substitute equation (3) into equation (4) to get:

[tex]2x-4=2[/tex]

Group similar terms:

[tex]2x=2+4[/tex]

[tex]2x=6[/tex]

Divide both sides by 2

[tex]\frac{2x}{2}=\frac{6}{2}[/tex]

This implies that:

Answer: Acute Angle

Step-by-step explanation:

Any angle 89 degrees or less will identify as an acute angle.  

A 43 degree angle can be classified as an acute angle.

A 43 degree angle is classified as an acute angle which means it measures less than 90 degrees. Acute angles are commonly found in many geometric shapes.

They are also often associated with sharp corners or narrow angles. In the case of a 43 degree angle, it is smaller than a right angle (90 degrees) but larger than a zero or null angle.

The true statements are for the spinner to be fair, each outcome will be equal, the relative frequencies in the table are relatively close and this means it is likely that the spinner is fair.

Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.

We know that, probability of an event = Number of favourable outcomes/Total number of outcomes.

Given that,

Outcome                      1            2          3           4

Relative frequency    0.26     0.24     0.24     0.26

The spinner has 4 sections

This means that the probability of landing in a section is:

p = 1/4

p = 0.25

Step-by-step explanation:

5*5*5*2

The number must end in 2 or 4.

1 3 and 5 will give you an odd number if either is at the end.

The permutation formula does not lend itself to this problem. That is because repetition is allowed. So 5554 is a possible answer.

You can choose any one of 1 to 5 for the first place.

1 to 5 in the second place independent of what you choose for the first place.

The only thing restricting you is the last place. It must be 1 of 2.

I suppose you could use 2P1 for that.

5 * 5 * 5 * 2P1

For this case we have by definition that one yard equals 91.44 centimeters.

We propose a rule of three that allows you to find the number of centimeters in any number of yards:

1yd ------------> 91.44cm

(28) + 3y = 28

Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. First, subtract 28 from both sides:

28 (-28) + 3y = 28 (-28)

3y = 0

Isolate the variable, y. Divide 3 from both sides:

(3y)/3 = (0)/3

y = 0

y = 0 is your answer.

Expression to simplify: [tex]\frac{8b}{a^{-5} }[/tex]

Remember, when a number has a negative power, it reciprocates (flips over)

First lets write the expression so that the a is in a fraction by itself:

[tex]\frac{8b}{a^{-5} }[/tex] = [tex]8b[/tex] × [tex]\frac{1}{a^{-5} }[/tex]

So to simplify, all we do is reciprocate [tex]\frac{1}{a^{-5} }[/tex] and make the power positive:

[tex]8b[/tex] × [tex]\frac{1}{a^{-5} }[/tex] =  [tex]8b[/tex] × [tex]a^{5}[/tex]

=[tex]8a^{5}b[/tex]

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

Answer:

[tex]8a^{5}b[/tex]

The correct simplification Expression is  [tex]8b/a^-5[/tex]

The correct simplification of the expression "8 times b over a to the power of -5" is [tex]8b/a^-5[/tex]. This can be simplified by using the following rule:

[tex]x^m \times x^n = x^ \ (m + n)[/tex]

Therefore, we can rewrite the expression as:

[tex]8b/a^-5 = 8b \times a^5[/tex]

We can then multiply the numerator and denominator by 8 to get:

[tex]8b \times a^5 = 64b \times a^5[/tex]

Finally, we can rearrange the factors to get:

[tex]64b \times a^5 = 8a^5 \times b[/tex]

Therefore, the simplified expression is [tex]8a^5 \times b.[/tex]
