Naomi made a triangular pyramid from cardboard. The triangular base has a height of 4 inches and a base length of 15 inches. The

height of the pyramid is 6 inches. If Naomi wants to double the volume of the pyramid, which method can she use? She can double the base length of the base so that the new volume is 120 cubic inches. She can double the base length of the base so that the new volume is 360 cubic inches. She can double both the base length and height of the base so that the new volume is 240 cubic inches. She can double both the base length and height of the base so that the new volume is 720 cubic inches.

tyrone opens an account at the local bank by depositing $50 of his birthday money. He continues to deposit $50 each month for 5
Pavel [41]

<u>Answer-</u>

<em>The amount will be </em><em>$8944.62</em><em> after 5 years.</em>

<u>Solution-</u>

We know that,

\text{FV of annuity}=P[\dfrac{(1+r)^n-1}{r}]

Where,

P = Payment = $50 monthly

r = rate of interest compounded monthly= 3\frac{1}{4}=3.25\%=0.0325

n = number of period = 5 years = 5×12 = 60 months

Putting the values in the formula,

\text{FV of annuity}=50[\dfrac{(1+0.0325)^{60}-1}{0.0325}]

=50[\dfrac{(1.0325)^{60}-1}{0.0325}]

=50[\dfrac{6.8140-1}{0.0325}]

=50[\dfrac{5.8140}{0.0325}]

=50\times 178.8923

=8944.62

Therefore, the amount will be $8944.62 after 5 years.

HELP?? A lunch combo has the following options: Entree: Hamburger, Hotdog, Chicken sandwich Side: Apples, Salad Drink: Milk, Wat
murzikaleks [220]

Using the Fundamental Counting Theorem, the sample size of these outcomes is of 12.

<h3>What is the Fundamental Counting Theorem?</h3>

It is a theorem that states that if there are n things, each with n_1, n_2, \cdots, n_n ways to be done, each thing independent of the other, the number of ways they can be done is:

N = n_1 \times n_2 \times \cdots \times n_n

Considering the number of options for Entree, Side and Drink, the parameters are:

n1 = 3, n2 = 2, n3 = 2.

Hence the sample size of outcomes is:

N = 3 x 2 x 2 = 12.

A 14-foot ladder is leaning against a building as shown. It touches a point 11 feet up on a building. How far away from the base
Luden [163]
We can assume that the point the ladder creates with the ground and building is a triangle. You can use the Pythagorean theorem to solve this.

A^2 + B^2 = C^2

The ladder is C, and the building can act as A or B, so for the purpose of this explanation, I’ll make it A.

11^2 + B^2 = 14^2
Figure out the squares

121 + B^2 = 196
Subtract 121 from both sides

B^2 = 75
Square root B^2 and 75

B = 5 root3
