F + g = 23
f+g-g=23-g
f = 23-g
f + 2g =34
23-g+2g=34
23+g=34
23-23+g=34-23
g = 11

f + g = 23
f + 11 = 23
f +11-11 =23-11
f = 12

Check
f + 2g =34
12 + 2(11) =34
12 + 22 = 34
34=34

She made 11 free throws and 12 field goals

Monica took out a 30-year loan for $130,000 at an APR of 8.4%, compounded monthly, and she is making monthly payments of $990.39

Over [174]

Answer: $ 40331.781 (Approx)

Step-by-step explanation:

Let Monica pay off $ x in 12 years,

Thus, for 12 years, his present value, PV = $ x

Given, APR of the loan = 8.4% = 0.084

Thus, the monthly rate of the loan, r = 0.084/12 = 0.007

The number of period in 12 years, n = 144

And, the monthly payment, P = $ 990.39

Thus, by the formula,

$\frac{r(PV)}{1-(1+r)^{-n}}=P$

$\frac{0.007 x}{1-(1+0.007)^{-144}} = 990.39$

$\frac{0.007 x}{1-0.36623195919}=990.39$

$\frac{0.007 x}{0.6337680408 } = 990.39$

$0.007 x=990.39\times 0.6337680408$

$0.007 x=627.677529937$

$x=89668.2185624$

Thus, He pay off $ 89668.2185624 of the original amount of the loan.

⇒The amount of loan left after 12 years

= 130,000 - 89668.2185624

=40331.7814376 ≈ $ 40331.781

For a project, you need to make three triangles out of cardboard. Each triangle has a height of 5 inches and a base of 10 inches

pashok25 [27]

Answer:

Option 1st is correct

$3 \cdot (\frac{1}{2} \cdot 10 \cdot 5)=x$

Step-by-step explanation:

Area of the triangle is given by:

$A = \frac{1}{2}bh$

where,

A is the area of the triangle

b is the base and

h is the height of the triangle.

As per the statement:

For a project, you need to make three triangles out of cardboard.

Each triangle has a height of 5 inches and a base of 10 inches

⇒b = 10 inches and h = 5 inches

$\text{Area of each triangle} = \frac{1}{2} \cdot 10 \cdot 5$

Since, you need to make three triangles out of cardboard

⇒ $\text{Area of 3 triangle}(x) =3 \cdot (\frac{1}{2} \cdot 10 \cdot 5)$

Therefore, an equation can you use to solve for the total amount of cardboard you will need is,

$3 \cdot (\frac{1}{2} \cdot 10 \cdot 5)=x$
