When a number is subtracted from half of its own square the result is 60. What is the number?

Answer:

A

Step-by-step explanation:

Because |x| would be absolute value.

Absolute value is always positive so If you had

|-7| it would equal 7.

The number line in option A is the only one that shows it.

Answer: option A

Step-by-step explanation:

Remember, the number line that is option A has absolute value.

So, it would mean this number line is the answer.

Hope it helps!

Answer:

70.68 inch is the volume of the rectangular prism

Step-by-step explanation:

V = w × h × l

V = 3.8 inch × 3 inch × 6.2 inch

V = 70.68 inch is the volume of the rectangular prism

To check:

70.68 ÷ 3.8 ÷ 6.2 = 3 inch (height)

70.68 ÷ 6.2 ÷ 3 = 3.8 inch (width)

70.68 ÷ 3.8 ÷ 3 = 6.2 inch (length)

Answer:

Domain: [-4,4]

Step-by-step explanation:

Domain is representative of the space on the graph that x occupies. Because all the points are closed, there should be closed or inclusive brackets outside of the domain. Because the lowest inclusive point is -4, that should be the first domain point. The graph continues until -2, where that line stops, but the second line begins at -2, so we include this point too, and there is no need to mention it in the domain. The second line ends at 4, so that is the highest end of the domain and would be the second domain point. Therefore the domain is [-4, 4]. Remember to keep closed brackets because of the closed points.

Answer:

x=20

Step-by-step explanation:

Complementary = 2 angles which = 90 degrees

so 2x+10 + x+20 =90

combine like terms

3x+30=90

    -30  -30

3x=60

x=20

lets check!        (2(20)+10) + (20+20)

                           50       +        40  =90 degrees

Answer:

x = 20

angle 1 = 50

angle 2 = 40

Step-by-step explanation:

complementary angles add up to 90

so, you can make this equation:

2x + 10 + x + 20 = 90

combine like terms

2x + x + 10 + 20 = 90

3x + 30 = 90

subtract 30 from both sides of the equation

3x + 30 - 30= 90 - 30

3x = 90 - 30

3x = 60

divide both sides of the equation by 3

3x/3 = 60/3

x = 60/3

x = 20

now, plug x into the angles:

2x + 10

2 * 20 + 10

40 + 10

the first angle is 50°

x + 20

20 + 20

the second angle is 40

Answer:

They are dependent

Step-by-step explanation:

A dependent event is one in which its chances of happenning greatly relies on another event. An independent event which is the opposite is one in which its chances of happening is unaffected by another event. In the event described in the question above returning the rented movie after the due date would result in receiving a late fee.

One of the events- receiving a late fee, depends on when the rented movie is returned. This means that the events are dependent.

Answer: 1 time

255 times 1 is 255. 255 plus 255 is 505. So only goes into 375 once.

Answer:

Step-by-step explanation:

Distance = speed * time

For Ben:

speed = 3mi/hr

Time = (x+1.5)hr

Distance = 3 * (x+1.5)

Distance = 3(x+1.5)

For Amanda:

Speed = 7mi/hr

time = 1x

Distance = 7x

Since they cover the same distance then:

3(x+1.5) = 7x

3x + 4.5= 7x

3x-7x = -4.5

-4x =-4.5

x = 4.5/4

x =  1.125 hr

The time taken  by Amanda is 1.125 hr

250%=2.5C=2.5100%=1C=1

Answer:

80 milligrams

Step-by-step explanation:

The volume of bottle is 16-ounce, and the amount of vitamin C in the bottle is 200 mg.

Since the 16-ounce bottle of orange juice says it contains 200 milligrams of vitamin C, which is 250% of the daily recommended allowance of vitamin C for adults. Then for 100% of the daily alowence, we need to multiply 200/250 by 10. We get 80. The picture shows a dubble number line for paper homework. Good luck!

Answer:

1,530

Step-by-step explanation:

box 1 (left one): 10*9*9=810

box 2 (right one): 18*4*10=720

720+810=1,530

Answer:

1530 cm^3

Step-by-step explanation:

They are two Rectangular Prism.

prism 1.

length l = 18 cm

width w = 10 cm

height h = 4 cm

diagonal d = 20.976177 cm

total surface area S_tot = 584 cm^2

lateral surface area S_lat = 224 cm^2

top surface area St_op = 180 cm2

bottom surface area S_bot = 180 cm^2

volume V = 720 cm^3

Prism 2.

length l = 10 cm

width w = 9 cm

height h = 9 cm

diagonal d = 16.1864141 cm

total surface area S_tot = 522 cm^2

lateral surface area S_lat = 342 cm^2

top surface area Stop = 90 cm^2

bottom surface area Sbot = 90 cm^2

volume V = 810 cm^3

Add 720 cm^3+810 cm^3 = 1530 cm^3

Agenda: l = length

w = width

h = height

d = diagonal

S_tot = total surface area

S_lat = lateral surface area

S_top = top surface area

S_bot = bottom surface area

V = volume

Formula: Volume of Rectangular Prism:  V = lwh

Answer:

$120

Step-by-step explanation:

$120-75% is $30. 1/4 of $120 is $30, so 3/4 is $90. $120-$90 is $30. To find the answer to future equations like this, just multiply the sales price by 4 if the percentage is 75.

It is not $52.50, because 75% of that is $39.375, making that one's sales price 13.125.

Answer:

$52.50 is the original price

Step-by-step explanation:

In order to find the answer, multiply $30 * 0.75 which equals $22.50 and add $30 + $22.50 which would equal $52.50

[tex]B = 30\%[/tex]

Required

Determine the probability that three selected are acceptable

This can be represented as:
