Answer:

D, Option A $\sqrt{3}$

Step-by-step explanation:

CE = $\sqrt{3}$ (by using pythagorean theorem

A = 1/2 bh

Kelsey can buy 2 pounds of apples for 7$. Write an equation to represent the cost, c, for a, pounds of apples.

zmey [24]

$\huge\boxed{c=3.5a}$

First, we need to find how much a single pound of apples costs.

Do this by dividing.

$\frac{\$7}{2\ \text{lbs.}}\div\frac{2}{2}=\frac{\$(7\div 2)}{(2\div 2)\ \text{lbs.}} = \frac{\boxed{\$3.50}}{1\ \text{lb.}}$

Now, write an equation.

$\large\boxed{c=3.5a}$

This represents that the cost equals 3.5 times the number of apples.

How many ways can 5 people be arranged in a line?

Rasek [7]

Answer: 120 ways

Step-by-step explanation: In this problem, we're asked how many ways can 5 people be arranged in a line.

Let's start by drawing 5 blanks to represent the 5 different positions in the line.

Now, we know that 5 different people can fill the spot in the first position. However, once the first position is filled, only 4 people can fill the second spot and once the second spot is filled, only 3 people can fill the third spot and so on. So we have 5 4 3 2 1.

Now, based on the counting principle, there are 5 x 4 x 3 x 2 x 1 ways for all 5 spots to be filled.

5 x 4 is 20, 20 x 3 is 60, 60 x 2 is 120, and 120 x 1 is 120.

So there are 120 ways for all 5 spots to be filled which means that there are 120 ways that 5 people can be arranged in a line.

If g(x) = -5x + 13, find g(-1)

givi [52]

To solve this problem, we must substitute the value of -1 in for x in the function. This means that for every x there is in the equation, we must substitute the value -1 in for it in order to find the value of g(-1). This is modeled below:

g(x) = -5x + 13

g(-1) = -5(-1) + 13

Next, we must simplify using the order of operations. PEMDAS outlines this concept, telling us to simplify parentheses first, exponents next, then multiplication and division, and finally addition and subtraction. In this case, we will solve the multiplication and then the addition, as modeled below:

g(-1) = -5(-1) + 13

g(-1) = 5 + 13

g(-1) = 18

Therefore, your answer is 18.

Hope this helps!

The area of square A is 900cm2, it is 3 times bigger than square B. What is the area of Square B?

emmasim [6.3K]

Answer: 8,100 cm^2

Step-by-step explanation: Area = S^2 so each side is sqrt(900) = 30cm

A square 3 times bigger has sides 30cm*3 = 90cm. The area for that square is 90^2 = 8,100 cm^2
