Answer:

100 x 3

Step-by-step explanation:

Well, it's a pretty simple problem.

If she already has 100 ants and it triples every month then, we'd multiply.

Key words like triple, double, twice as much can signal that a problem requires multiplication.

In this case, we'd do 100 x 3

which means that after one month, she'd have 300 ants.

Answer: C- 17 hrs /2 weeks

Step-by-step explanation:

Write the number of hours in the numerator and the number of weeks in the denominator.

68 hrs/8 weeks

Simplify by dividing 4 into both the numerator and denominator.

68/8 = 17/2

Answer:

-720

Step-by-step explanation:

10x^3y^2    If x = -2 and y = -3

10 * (-2^3) * (-3^2)

10 * (-8) * (9) = -720

Answer:

A.) -720

Step-by-step explanation:

10x^3y^2

10 times x^3 times y^2

x = -2

y = -3

10 times (-2)^3 times (-3)^2

-2^3 = -2 x -2 x -2 = -8

-3^2 = -3 x -3 = 9

-8 x 9 = -72

10 x -72 = -720

Answer:

she can earns $28

Step-by-step explanation:

Answer:

$24.40

Step-by-step explanation:

if she gets $8 per hour than in 3 hours she would have earned $24 cause 8*3=24.

since she works for 3h and 30 min to find the 30 min we have to divide 8 by 2 becasue 30 min is halve an hour so by doing this you get 8/2=4

Answer:

18:19

Step-by-step explanation:

Given that,

The radius of circle A = 9 cm

The diameter of circle B = 19 cm

We know that,

Radius = diameter/2

The radius of circle B = 19/2 cm

The circumference of circle A is :

[tex]C_A=2\pi r_A[/tex] ....(1)

And that of circle B is :

[tex]C_B=2\pi r_B[/tex] ....(2)

Dividing equation (1) and (2) :

[tex]\dfrac{C_A}{C_B}=\dfrac{2\pi r_A}{2\pi r_B}\\\\=\dfrac{r_A}{r_B}\\\\=\dfrac{9}{\dfrac{19}{2}}\\\\\dfrac{C_A}{C_B}=\dfrac{18}{19}[/tex]

Hence, the ratio of circumferences of Circle A and Circle B is 18:19.

Answer:

I think is (x+0,5)^{2} - 6,25

Step-by-step explanation:

a(x-h)square + k

Answer: y = x² + x - 6

the equation is y = ax² + bx + c (a ≠ 0)

see in the graph, the equation passed through (-3;0), (2;0) and (0;-6), so we have:

9a - 3b + c = 0

4a + 2b + c = 0

c = -6

=> a = 1

    b = 1

    c = -6

=> the equation is y = x² + x - 6

[tex]2\ cm[/tex]

Step-by-step explanation:

[tex]We\ are\ given\ that,\\Radius\ of\ the\ conical\ vessel=5\ cm\\Height\ of\ the\ conical\ vessel=24\ cm\\Hence,\\As\ we\ know\ that,\\Volume\ of\ a\ cone=\frac{1}{3}\pi r^2h\\Hence,\\The\ volume\ of\ the\ conical\ vessel=\frac{1}{3}\pi (5)^224= \frac{1}{3}\pi 25*24=200\pi \\Hence,\\The\ volume\ of\ the\ conical\ vessel=The\ amount\ of\ water\ filled\ in\ it\\Hence,\\The\ amount\ of\ water\ filled\ in\ the\ conical\ vessel=200\pi\\Lets\ consider\ the\ cylindrical\ vessel:\\Volume\ of\ a\ cylinder=\pi r^2h[/tex]

[tex]As\ we\ are\ not\ said\ that\ the\ cylindrical\ vessel\ was\ empty,\ let\ its\ initial\\ height\ be\ h_1\\Radius\ of\ the\ Cylindrical\ vessel=10\ cm\\Initial\ height\ of\ the\ cylindrical\ vessel=h_1\\Initial\ volume\ of\ the\ cylindrical\ vessel=\pi *10^2*h_1=100h_1\pi \\Initial\ amount\ of\ water\ in\ the\ cylindrical\ vessel=100h_1\pi \\Hence,\\Final\ amount\ of\ water\ in\ the\ cylindrical\ vessel=Final\ amount\ of\ water\\ in\ the\ cylindrical\ vessel +Amount\ of\ water\ in\ conical\ vessel[/tex]

[tex]Hence,\\Final\ amount\ of\ water\ in\ the\ cylindrical\ vessel=100h_1\pi +200\pi \\Now,\\Let\ the\ final\ height\ be\ h_2\\Hence,\\Final\ amount\ of\ water\ in\ the\ cylindrical\ vessel=\pi *10^2*h_2=100h_2\pi \\Hence,\\100h_2\pi =100h_1\pi +200\pi \\Hence,\\100h_2=100h_1+200\\100h_2-100h_1=200\\100(h_2-h_1)=200\\h_2-h_1=2\\Hence,\\As\ the\ rise\ in\ level\ is\ the\ difference\ between\ the\ initial\ and\ final\\ heights:\\The\ rise\ in\ level\ of\ water=2\ cm[/tex]

Answer:

1/2

Step-by-step explanation:

Since you are going from the biggest to smallest, it would be 1/2. If you are going from the smallest to biggest it would be 2. So the answer is 1/2. :)

Given:

[tex]\dfrac{10}{24}[/tex] and [tex]\dfrac{5}{12}[/tex].

To find:

The relationship between the ratios.

Solution:

We have, two ratios in the fraction form.

[tex]\dfrac{10}{24}[/tex] and [tex]\dfrac{5}{12}[/tex]

First ratio = [tex]\dfrac{10}{24}[/tex]

                = [tex]\dfrac{2\times 5}{2\times 12}[/tex]

                =[tex]\dfrac{5}{12}[/tex]           (Cancel out the common factors)

First ratio = Second ratio

Since, the both ratios are equal to each other, therefore, the given ratios are equivalent ratios.

Answer:

her average speed is 7 and 2/3 miles per hour

Step-by-step explanation:

The solution of the equation 70 = 1.4y is 50.

Two or more expressions with an Equal sign is called as Equation.

The given equation is 70 = 1.4y.

Seventy equal to one point four y.

In the given equation the variable is y.

We need to solve for the y.

70 = 1.4y.

Divide both sides by 1.4

70/1.4=y

Seventy divided by one point four equal to y

50=y

The value of y is fifty.

Hence, the solution of the equation 70 = 1.4y is 50.
