Answer:

42 girls and 18 boys

Step-by-step explanation:

if you write out 7 lines 6 times to represent the girls you have 42 and 3 lines 6 times to represent boys you have 18. 18+42=60. sometimes it just helps to draw it out to visualize it

Y² - 12y + 32

The middle term must be written in such a way that the sum of two numbers is -12y and the product is 32y²

The two such numbers are -4y and -8y

So, we can write:

y² - 4y - 8y + 32

= y(y - 4) - 8(y - 4)

= (y - 4)(y - 8)

So, option B gives the correct answer

A two gallon container had all of its dimensions tripled. How many gallons does the new container hold?
Vaselesa [24]

Answer:

8

Step-by-step explanation:

In this situation if the two gallon container will have all of its dimensions tripled, then that means the the volume of the container will also get tripled.

When all the dimensions of a shape are changed, the volume will then also change accordingly.

Since the original container held 2 gallons, we will then solve for the value by simply raising 2 to the power of 3.

2³ = 8

Now why did we raise the number of gallons by three instead of multiplying it directly by 3?

We did that, because we need to consider that the entire container had all of its dimensions tripled. When a shapes dimensions are all increased, this means that it will grow exponentially.

Suppose you invest $2250 in a D that earns 3% APR and is compounded monthly. The Cd matures in 2 years. How much will this CD be
olasank [31]

Answer:

$2388.95

Step-by-step explanation:

  • Principal, P= $2250
  • Annual Interest Rate, r= 3% =0.03
  • Time, n= 2 years
  • Since it is compounded monthly, Period, k= 12 Months

The worth of a compound deposit after a period of n years is calculated using the formula:

A(n)=P(1+\frac{r}{k})^{nk}

A(2)=2250(1+\frac{0.03}{12})^{12 \times 2}\\\\=2250(1+0.0025)^{24}\\=2250(1.0025)^{24}\\=\$2388.95

At maturity, the deposit will be worth $2388.95.
