Answers

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

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.

A collector bought 47 coins at auction, some bronze and some silver. The bronze coins cost him $ 14 each and the silver coins, $ 18 each. If in total he spent $ 750, how many bronze coins did he buy and how many silver?

(with the steps)

please help me, it's for an exam

Answers

24 bronze coins and 23 silver coins

B= bronze coins S = silver coins
$14xB + $18 x S =$750
B + S = 47 total coins
Get in terms of S=47-B by subtracting B from each side, then replace the S in the first equation with this so that:
14xB+18x(47-B)=750
14B+846-18B=750
Subtract the 846 and combine the abs
-4B=-96 then divide the -4 on both sides
To get B=24 then 47-24=23=S

The population P, in millions, of a certain country can be modeled by the function P(t) = 3.98(1.02)t, where t is the number of years after 1990.

Answers

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

What is the value of x?

Thanks

Answers

Answer:

x = 6√3

Step-by-step explanation:

Let's just look at the right triangle. This is a 30° 60° 90° triangle. The value of the large leg (x) will be the value of the small leg times √3. The value of the hypotenuse (12) is the value of the small leg times 2. Since we know that, we can divide 12 by 2 to find out the value of the small leg will be 6. Finally, know that we know that 6 is the value of the small leg, we can multiply 6 by √3 to find that the value of x = 6√3.

Answer: [tex]6\sqrt{3}[/tex]

Step-by-step explanation:

This is a 30-60-90 triangle because we know that there is a right angle and a 60 degree angle

the side opposite to 30 degrees is a, 90 degrees is 2a, and the side opposite to 30 degrees is [tex]a\sqrt{3}[/tex]

2a = 12 so a = 6 and  [tex]a\sqrt{3}[/tex] is [tex]6\sqrt{3}[/tex]
