HELP PLEASE IM ON A TIMER!!!
To buy a PS5 bundle, Amir borrowed $850 for 2 years at a simple interest rate of 2.5%. How much did he have to pay back in all? A.$42.50 B.85.00 C.$850 D.$892.50
Answers
Answer:
d.
Step-by-step explanation:
Answer:
D. $892.50
Step-by-step explanation:
First we find out the interest:
850 * 2.5% = 21.25
Since this is 2 years we multiply the interest by 2.
21.25 * 2 = 42.50
Now we add the interest with the amount borrowed.
850 + 42.50 = $892.50
So, the answer is $892.50 in total.
Hope this helps! :)

if f(x)=2x+1 and g(x)=x2 find fg(3)
Answers
Given:
The functions are:
[tex]f(x)=2x+1[/tex]
[tex]g(x)=x^2[/tex]
To find:
The value of [tex]fg(3)[/tex].
Solution:
We have,
[tex]f(x)=2x+1[/tex]
[tex]g(x)=x^2[/tex]
Substitute [tex]x=3[/tex] in each function.
[tex]f(3)=2(3)+1[/tex]
[tex]f(3)=6+1[/tex]
[tex]f(3)=7[/tex]
And,
[tex]g(3)=(3)^2[/tex]
[tex]g(3)=9[/tex]
We know that, product of two functions is defined as:
[tex]fg(x)=f(x)\times g(x)[/tex]
Using this rule, we get
[tex]fg(3)=f(3)\times g(3)[/tex]
[tex]fg(3)=7\times 9[/tex]
[tex]fg(3)=63[/tex]
Therefore, the value of [tex]fg(3)[/tex] is 63.

Answer: V = 600 unit 2
Step-by-step explanation:
We have that
the volume of the rectangular pyramid is
V = (1/3) BH
where
B is the area of the rectangular face
H is the height of the pyramid
step 1
Find out B
B = (15)(10) unit 2
step 2
Find the volume
B = 150 unit 2
H = 12 unit
substitute
V = (1/3)(150)(12)
V = 600 unit 2

Answers
Answer:
BD = 3.2.
CD = 2.4.
Step-by-step explanation:
By Pythagoras:
AB^2 = 3^2 + 4^2 = 25
AB = 5.
Triangles ADC and ACB are similar, so
AC / AB = AD / AC
3 / 5 = AD / 3
AD = 3*3/5
AD = 9/5 = 1.8
So BD = 5 - 1.8
= 3.2.
CD^2 = AC^2 - AD^2 (Pythagoras)
CD^2 = 3^2 - 1.8^2 = 5.76
CD = 2.4.

The volume of a cylinder is 720π cm3. The height of the cylinder is 20 cm. What is the radius of the cylinder?
Answers
Answer:
Radius = 3.38 cm
Step-by-step explanation:
Here's your solution
=> The volume of cylinder = 720π cm^3
=> The height of cylinder = 20 cm
=> Radius = ?
=> Formula of volume of cylinder = πr^2h
=> 22/7 * r^2 * 20 = 720π cm^3
=> r^2 = (720*7)/20*22
=> r^2 = 11.45
=> r = √11.45
=> r = 3.38 cm
