Answer:

C) Addition property of equality and division property of equality

Step-by-step explanation:

To find the answer, let's first solve the equation for x...

3x-6=12

Add 6 to both sides (Addition property of equality)

3x=6

Divide both sides by 3 (Division property of equality)

x=2

We used both the addition property of equality and the division property of equality therefore the answer is C

Okay, so the function is to do x times 2, then subtract 4.

6 x 2 = 12, 12 - 4 = 8. The first one is 8.

2 x 2 = 4. 4 - 4 = 0.

-4 x 2 = -8. -8 - 4 = -12. The last is -12.

With this information we can tell that it is C, 8, 0, -12.

A factor is what makes up a multiplication sentence. It is a number that is multiplied with another number that gives us the product, the answer to a multiplication sentence.

Answer:

x = 21

Step-by-step explanation:

Using ratios:

75 : 25 = x : 7

75/25 = x/7

3 = x/7

21 = x

Using Pythagoras' Theorem a² + b² = c², where a and b are the legs and c is the hypotenuse of a right triangle:

[tex]72^2+x^2=75^2[/tex]

[tex]\implies x^2=75^2-72^2[/tex]

[tex]\implies x=\sqrt{75^2-72^2}[/tex]

[tex]\implies x=21[/tex]

Answer:

21 degrees

Step-by-step explanation:

I'm assuming that the 0 is supposed to be theta, which I'm replacing with x to make it easier for me to type.

Because these angles are acute, we can use the fact that if two angles A and B are complementary, then sinA = cosB.

So we can get that x+4+3x+2=90

4x+6=90

4x=84

x=21

Answer:

The cost for a towel at 4 for $17 is:

17/4 = 4.25 $/towel

The cost for a towel at 2 for $9 is:

9/2 = 4.5 $/towel

So Shaunda is correct, as the cost per towel for 4 at $17 is lower.

Answer:

[tex]\displaystyle y = \frac{1}{4}\, x + 2[/tex].

Step-by-step explanation:

The question is asking for the slope-intercept equation of a line. The slope-intercept form equation of a line is in the form [tex]y = m\, x + b[/tex], where:

For example, the equation of the first line, [tex]y = -4\, x + 1[/tex], is given in slope-intercept form. The slope of that line is [tex]m_{1} = (-4)[/tex] while the [tex]y[/tex]-intercept of that line is [tex]b_{1} = 1[/tex].

Both [tex]m[/tex] and [tex]b[/tex] need to be found for the second line.

Start by finding the slope [tex]m_{2}[/tex] of the second line.

Make use of the fact that if two lines in a plane are perpendicular to one another, the product of their slopes would be [tex](-1)[/tex]. In other words, if a line with slope [tex]m_{1}[/tex] is perpendicular to a line with slope [tex]m_{2}[/tex], then [tex]m_{1}\, m_{2} = (-1)[/tex]. Rearrange to obtain [tex]m_{2} = (-1) / m_{1}[/tex].

In this question, since the slope of the first line is [tex]m_{1} = (-4)[/tex], the slope of the second line (perpendicular to the first line) would be [tex]m_{2} = (-1) / (-4) = (1/4)[/tex].

Thus, the equation of the second line would be of the form [tex]\displaystyle y = (1/4)\, x + b_{2}[/tex] for some constant [tex]b_{2}[/tex] that needs to be found.

Make use of the fact that the second line goes through the point [tex](-4,\, 1)[/tex] to find the value of [tex]b_{2}[/tex]. Since the point [tex](-4,\, 1)\![/tex] is on the second line, the equation of the second line should hold after substituting in [tex]x = (-4)[/tex] and [tex]y = 1[/tex]. That is:

[tex]1 = (1/4)\times (-4) + b_{2}[/tex].

Solve this equation for [tex]b_{2}[/tex]:

[tex]b_{2} = 2[/tex].

Therefore, the equation of the second line would be [tex]y = (1/4)\, x + 2[/tex].

Hope this helped

Step-by-step explanation:

the volume of the tank is

80×50×45 = 180,000 cm³

3/4 of that volume is

180000 × 3/4 = 135,000 cm³

so, we want to know how long it takes to fill 135,000 cm³.

the water intake flow is 9 l / minute.

now we need to know that a cube of 10 cm side length contains exactly 1 liter of water.

such a cube has the volume

10×10×10 = 10³ = 1000 cm³

so, 1000 cm³ = 1 liter.

and we need to fill 135,000 cm³.

how many times fit 1000 cm³ into 135,000 cm³ ?

135000/1000 = 135 times.

and that means it would take 135 minutes to fill it, if the flow was 1 l / minute.

but it is faster (9 times faster) : 9 l / minute

so, how many minutes ?

135 / 9 = 15 minutes

it takes 15 minutes to fill 3/4 of the tank.

Answer:

15 minutes

Step-by-step explanation:

The volume (V) of the tank is calculated as

V = lbh (l is the length, b the breadth and h the height (

here l = 80, b = 50, h = 45 , then

V = 80 × 50 × 45 = 180000 cm³

1 litre = 1000 cm³ , then

9 litres = 9 × 1000 = 9000 cm³

Divide the volume of the tank by 9000 for time in minutes

180000 ÷ 9000 = 20 minutes

It takes [tex]\frac{3}{4}[/tex] × 20 = 15 minutes to fill [tex]\frac{3}{4}[/tex] of the tank

Answer: 2x+3 and -1

Step-by-step explanation:

a)

[tex]A=\pi r^2 = 4\pi x^2 + 12\pi x + 9\pi\\r^2 = 4x^2 + 12x + 9\\r^2 = (2x+3)^2\\r = 2x+3[/tex]

b) Radius has to be greater than 0, so 2x + 3 > 0

2x > -3

x > -1.5

So least possible integer value is -1

Answer:

Step-by-step explanation:

We can count two heads out of 3 coin tosses, this is 10 out of 25:

The experimental probability of getting exactly 2 heads out of 3 coin tosses is 40% option second is correct.

It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.

The total outcome set

T = {HTT, HHH, HTH, THT, THH, THT, THH, THT, HHT, TTH, HHH, TTT, HHT, THH, HTT, HHH, THT, HTT, HHT, HTH, THH, HTT, THH, TTH, HTT}

n(T) = 25

Total favourable outcome n(E) = 10

The probability = 10/25 = 0.4

= 0.4×100 = 40%

Thus, the experimental probability of getting exactly 2 heads out of 3 coin tosses is 40% option second is correct.

Answer:

it's C

Step-by-step explanation:

Astronomers measure large distances in light-years. One light-year is the distance that light can travel in one year, or approximately  5.88\times 10^{12}5.88×1012 miles. Suppose a star is 2.23\times 10^22.23×102 light years from Earth.

To find : In scientific notation, how many miles away a star is from earth?

Solution :

One light-year is the distance that light can travel in one year is 5.88\times 10^{12}5.88×1012 miles.

In 2.23\times 10^22.23×102 lights year the distance is  

=5.88\times 10^{12}\times 2.23\times 10^2=5.88×1012×2.23×102

=1.31124\times10^{15}=1.31124×1015

Therefore, Option C is correct.
