Answer:

48

Step-by-step explanation:

Answer: Her mom is 48 years old.

Step-by-step explanation:

If

12 = 1/4 of x (her mom's age)

12 divided by 1/4

12    x  4                       = 48

1            1

x = 48

Step-by-step explanation:

5.5 litres paint needed for 1 stool

1  litres paint needed for  1/ 5.5

20 litres paint needed for  20/5.5

= 3.636

And now comes the twist, you can't paint 3.6 stools. also You can't paint 4 stools. You need to round down to 3

Answer:

n = -18/7

Step-by-step explanation:

Represent the number with n.

Then:

n - 6 = -6(n + 4)

Performing the indicated multiplication, we get:

n - 6 = -6n - 24

Combining like terms results in 7n = -18, so n = -18/7

Answer:

This is a geometric sequence and the ratio is equal to 4.

Step-by-step explanation:

Arithmetic means you can continue the sequence through addition or subtraction.

Geometric means you can continue the sequence through multiplication or division.

To get from 3 to 12, we could either add 9 (arithmetic) or multiply by 4 (geometric).

To get from 12 to 48, we could either add 36 or multiply by 4.

Since we are looking for a pattern, the sequence would be geometric. This is because the sequence can be continued by multiplying by 4 each time. It cannot be arithmetic because we cannot add by 9 each time.

On a side note, common difference is used when describing arithmetic while ratio is used to describe geometric.

Answer:

49 is equal to 7 times 7

Step-by-step explanation:

perfect squares are a number that are the product of the same number e.g. 4*4=16, 5*5=25

Answer:

X - 1 = X + 4

2 3

X- 2 = X + 12

2 3

3(x - 2) = 2(x + 12)

3x - 6 = 2x + 24

X = 18

Answer:

51, 52, 53

Step-by-step explanation:

51, 52, and 53 are all greater than 50, but less than 54

The possible numbers that Adam could have written are any number between 50 and 54, such as 51, 52, or 53.

Number systems are mathematical systems that are used to express numbers in various ways.

Given that the number is "greater than 50 and less than 54", which means it must be strictly between those two values.

Here, the range of numbers that Adam could have written is (50, 54), which means any number greater than 50 and less than 54, but not including 50 and 54 themselves.

Thus, the possible numbers that Adam could have written are any number between 50 and 54, such as 51, 52, or 53.

Answer:

10x

Step-by-step explanation:

Given the expression 60x^3- 10x^2+ 30x, we are to find the GCF

First let us find the factors of each terms

60x³ = 6 * (10 * x) * x²

10x² = 1 * (10 * x) * x

30x = 3 * (10 * x)

From the three factors, you can see that 10*x is common to them all. Hence the GCF of the expression will be 10x

Answer:

The maximum height of the ball is 380.25 feet in the air.

Step-by-step explanation:

The quadratic function:

[tex]h(t)=-16t^2+132t+108[/tex]

Models the ball's height h(t), in feet, above the ground t seconds after it was thrown.

We want to determine the maximum height of the ball.

Note that this is a quadratic function. Therefore, the maximum or minimum value will always occur at its vertex point.

Since our leading coefficient is leading, we have a maximum point. So to find the maximum height, we will find the vertex. The vertex of a quadratic equation is given by:

[tex]\displaystyle \left(-\frac{b}{2a},f\left(\frac{b}{2a}\right)\right)[/tex]

In this case, a = -16, b = 132, and c = 108. Find the t-coordinate of the vertex:

[tex]\displaystyle t=-\frac{132}{2(-16)}=-\frac{132}{-32}=\frac{33}{8}=4.125[/tex]

So, the maximum height occurs after 4.125 seconds of the ball being thrown.

To find the maximum height, substitute this value back into the equation. Thus:

[tex]h(4.125)=-16(4.125)^2+132(4.125)+108=380.25\text{ feet}[/tex]

The maximum height of the ball is 380.25 feet in the air.

Answer:

$4

Step-by-step explanation:

32/4 = $8 per pound

so 1/2 pound = 1/2 x 8 = $4

it is either the second one or the last one

Answer:

For (a) the answer is 450, 50(9)=450 total blocks.

Step-by-step explanation:

For (c), you will have to use a scale of 1 to 5, so, 450(5)=2,250.

For (b), if the map is 21 square inches and you want to enlarge it to the size you want, you would have to take the total value of the original map and multiply it by whatever factor it has to be multiplied by.

Now finally for (d), I applied proportional reasoning by looking at the dimensions and adding them all together to get the area value, then comparing the area value to the enlarged figure or decreased figure.

(I did this quite a long while ago, I'm going based on my memory and math skills, sorry if I failed horrendously.)

Number of households without computer in 2009

From the attachment, we have:

[tex]n=5170000[/tex] --- survey

[tex]p = 22.3\%[/tex] --- proportion without computer

So, the actual number is:

[tex]Number = p * n[/tex]

[tex]Number = 22.3\% * 5170000[/tex]

[tex]Number = 1152910[/tex]

[tex]Number \approx 1153000[/tex]

Answer:

(√6x√20) / √3 = 2√10

Step-by-step explanation:

hello :

(√6x√20) / √3 =√2x√3 x√4x√5 / √3

because : √6 = √2x√3 and √20= √4x√5 = 2x√5

now simplify by √3 :(√6x√20) / √3 =√2x2x√5

(√6x√20) / √3 = 2√10 so : a =2 and b =10

Answer:

B

Step-by-step explanation:

To find the y- intercept let x = 0

From the table for f(x)

When x = 0 → f(x) = - 4

That is the y- intercept = - 4

Given

g(x) = 3 [tex](2)^{x}[/tex]

let x = 0 , then

g(0) = 3 [tex](2)^{0}[/tex] [ [tex]2^{0}[/tex] = 1 ]

       = 3 × 1

       = 3

That is the y- intercept = 3

Thus the y- intercept of g(x) is greater → B
