Pavlova-9 [17]

<h2>It represents that , the amount of money in the bank account is $1680 after 50 months.</h2>

Step-by-step explanation:

Given , the amount of money in a bank account can be represented by the equation A(m) = 30m +180, where A(m) is measured in dollar and m is measured in month.

When A(m) = 1680

1680 = 30m +180

⇔30m = 1680 -180

⇔30m = 1500

⇔ $m= \frac{1500}{30}$

⇔ m = 50

It represents that , the amount of money in the bank account is $1680 after 50 months.

Choose the correct factorization for the polynomial.

Natasha_Volkova [10]

Answer:

D (4y-5)(3x-5)

Step-by-step explanation:

12xy -15x -20y +25

I will factor by grouping

12xy -15x -20y +25

Factor out 3x from the first group and -5 from the second group

3x(4y-5) -5(4y-5)

Now factor out (4y-5)

(4y-5)(3x-5)

Find the volume of the cone. Use 3.14 for π. Round to the nearest tenth.

Leviafan [203]

$Volume\,\,of\,\,cone=1527.1\,\,cm^3$

So, Option C is correct.

Step-by-step explanation:

We need to find Volume of cone.

We are given:

π = 3.14

Length = 27 cm

Diameter = 15 cm

The formula used to find Volume of cone is:

$Volume\,\,of\,\,cone=\frac{1}{3}\pi r^2h$

We are given diameter but we need radius in the formula

So, Radius = Diameter/2 = 15/2 = 7.5 cm

We need to find height of cone.

Using Pythagoras theorem:

$h^2=p^2+b^2\\ (27)^2=p^2+(7.5)^2\\729=p^2+56.25\\p^2=729-56.25\\p^2=672.75\\Taking\,\,square\,\,root:\\p=25.93$

So, Height of cone = p= 25.93

So, r= 7.5 and h= 25.93 and π = 3.14

Putting values in the formula:

$Volume\,\,of\,\,cone=\frac{1}{3}3.14*(7.5)^2*25.93$

$Volume\,\,of\,\,cone=1526.62$

Rounding off to the nearest tenth:

$Volume\,\,of\,\,cone=1527.1\,\,cm^3$

So, Option C is correct.

SSSSS [86.1K]

Answer:

The answer is B. He spent 3 minutes eating lunch for every 10 minutes.

Step-by-step explanation:

He spent stuck inside during the brainstorm for:

20+18+12+10= 60 minutes in total.

And now we want to know what he did for every 10 minutes he spent in the rainstorm. To do that we need to divide what he did for every 10 minutes by the total of minutes that he was stuck:

$\frac{10}{60} =\frac{1}{6}$
