Answer:

  $503.85

Step-by-step explanation:

The amortization formula can help with this.

  A = P(r/12)/(1 -(1 +r/12)^(-n))

where P is the loan value, A is the monthly payment, r is the annual interest rate, and n is the number of monthly payments.

We want to find P. All of the other values are given.

  P = A(1 -(1 +r/12)^-n)/(r/12)

  P = 32.48(1 -1.012667^-18)/(0.012667) = 31.48·16.0054

  P ≈ 503.85

The equivalent cash price is about $503.85.

Answer:

7.35 Million

Step-by-step explanation:

So you already have the function and all you have to do is find the years.

p(t)=3.98(1.02)^t

I'm thinking that you should find the difference between 2021 and 1990. The answer would be 31 and just substitute that from t.

p(t)=3.98(1.02)^31

From here you would jut plug this function into your calculator and get a final answer of:

7.35 Million

Step-by-step explanation:

i dont know

Answer:

I think it is correct and is 1 and 2

Step-by-step explanation:

5×4^(x+1)-16^x=64

0=64+16^x-5×4¹×4^x

0=(4^x)²-2×4^x×10+10²-10²+64

0=(4^x-10)²-36

(4^x-10)²=36

4^x-10=√36

4^x=+-6+10

when positive

4^x=4²

:.x=2

when negative

4^x=4

:.x=1

:.x=1,2 answer.

Problem 3

Explanation: The angles opposite the congruent sides, are congruent angles. We consider these the base angles. This triangle is isosceles.

==================================================

Problem 4

Explanation:

Refer to the diagram below. Note how I've added in the variable y and marked another angle as 53 degrees which is one of the base angles of the left triangle. The base angles of the triangle on the right are y degrees each. Also, note the vertical angles both are y.

For the left triangle, the three angles add up to 180 which means we can solve for y to go from 53+53+y = 180 to y = 74

Then the interior angles of the triangle on the right has the three angles (y,y,x) add to 180 as well. So we have y+y+x = 180 which turns into 74+74+x = 180. That solves to x = 32

==================================================

Problem 5

Explanation:

Refer to the diagram below. I've added another base angle x, and the angle 90-x is complementary to this. This is because the two pieces must add to 90.

For the triangle on the bottom, the two base angles 74 and 74, add to the third angle 90-x and we would get 180. So we solve 74+74+(90-x) = 180 to get x = 58

Answer:

3. x = 47

4. x = 32

5. x = 58

Step-by-step explanation:

Answer:

y = -15x + 35

Step-by-step explanation:

3x + 1/5y = 7

1/5y = -3x + 7

y = 5( -3x + 7)

y = -15x + 35

Answer:

110

Step-by-step explanation:

They are equal to each other.

23x-5= 21x +5

2x = 10

x = 5

21(5) +5 = 110°

23(5) -5 = 110°

So it works. Angles are 110°

Answer:

The submarine would be 179 feet below sea level

Step-by-step explanation:

m = 7

13 x 7 = 91

-270 + 91 = -179

After 7 minutes submarine was at -17 feet.

An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.

Given that, the expression - 270+ 13m represents a submarine that began at a depth of 270 feet below sea level and ascended at a rate of 13 feet per minute.

A) Here, m=7

-270+13(7)

= -270+91

= -179

B) No

Therefore, after 7 minutes submarine was at -17 feet.

Complete question :

Angela makes a pillow in the shape of a wedge to use for watching TV. The pillow is filled with 0.35 m3 of fluffy material, with base 0.5 m and height 1m

What is the length of the pillow?

Answer:

1.4 m

Step-by-step explanation:

The volume of wedge is given by:

V = Area of triangle * length

Area of triangle = 1/2 * base * height

Volume of wedge = 1/2 * base * height * length

Volume of wedge = 0.35m³

0.35 = 0.5 * 0.5 * 1 * length

0.35 = 0.25 * length

Length = 0.35 / 0.25

Length = 1.4 m

1.4

I took the test! Hope this helps <3

Answer:

See explanation below

Step-by-step explanation:

This is actually pretty easy to explain, and we all need to do is work with fractions.

So we have a recipe for chicken and rice, but the person decides to use 2/3 of the recipe. to determine the quantity of each ingredient to be used, we just need to multiply the cups of each ingredient by 2/3, and that's it.

Let's go with each ingredient, one by one:

Chicken broth 2 2/3 cups:

In this case, let's convert the 2 2/3 to a simple fraction. (We just multiply the denominator by the single number and then, sum the numerator)

2 2/3 = (3*2) + 2 / 3 = 8/3 of cups

8/3 * 2/3 = 16/9 cups of chicken.

But to do this better, let's convert this into a mix fraction:

16 : 9 = 1  and the rest is 7 so:

Chicken 1 1/2 cups:

We'll do the same thing as before:

1 1/2 = (2*1) + 1 / 2 = 3/2 of cups

3/2 * 2/3 = 1

3/4 cups or rice:

3/4 * 2/3 = 1/2
