the equation for simple interest is I= p r t (I=interest, p=principal, r=rate, t=time) Find the simple interest paid to the nearest cent for a loan of $1750 at 12% for 18 months (1.5 years).
Answer:
Simple Interest = $315
Step-by-step explanation:
The formula for Simple Interest
I = P× R × T
I=interest, p=principal, r=rate, t=time
P = $1750
R = 12% = 0.12
T = 1.5 years
I = $1750 × 0.12 × 1.5
I = $315
For the function f (x) = 3 (x + 7), find -1().
Given:
The function is [tex]f(x)=3(x+7)^{\frac{1}{4}}[/tex].
To find:
The function [tex]f^{-1}(x)[/tex].
Solution:
We have,
[tex]f(x)=3(x+7)^{\frac{1}{4}}[/tex]
Substitute f(x)=y.
[tex]y=3(x+7)^{\frac{1}{4}}[/tex]
Interchange x and y.
[tex]x=3(y+7)^{\frac{1}{4}}[/tex]
Divide both sides by 3.
[tex]\dfrac{x}{3}=(y+7)^{\frac{1}{4}}[/tex]
Taking power 4 on both sides.
[tex]\left(\dfrac{x}{3}\right)^4=y+7[/tex]
Subtract 7 from both sides.
[tex]\left(\dfrac{x}{3}\right)^4-7=y[/tex]
[tex]y=\left(\dfrac{x}{3}\right)^4-7[/tex]
Substitute [tex]y=f^{-1}(x)[/tex].
[tex]f^{-1}(x)=\left(\dfrac{x}{3}\right)^4-7[/tex]
Therefore, the correct option is C.

Solve for r.
Ar + By = C
Answer:
r = (C - By) / A
Step-by-step explanation:
Ar + By = C
_________
-By -By
[Subtract both sides by By (Subtraction poe)]
Ar = C - By
________
(Ar) = (C - By)
[Use parenthesis to group both terms (Associative property of equality)]
________
÷A ÷A
[Divide both sides by A to isolate r so it can be solved (Division poe)]
________
r = (C - By) / A
Which expression can be used to find the total cost of 4 bags of apples at $3.30 per bag and 6 candy bars at $1.25 each? *
4(1.25) + 6(3.3)

4(3.30) + 6(1.25)
4(3.30) - 6(1.25)
Answer:
a
Step-by-step explanation:
Answer:
4(3.30)+ 6(1.25)
Step-by-step explanation:

*The length of the congruent sides of an isosceles triangle is 17cm. If the base of the triangle is 16 cm, find the length of the median.*
1️⃣ 18 cm
2️⃣ 8 cm
3️⃣ 15 cm
4️⃣ 8.5 cm
Answer:
The median is 15cm.
Step-by-step explanation:
Given that the The length of the congruent sides of an isosceles triangle is 17cm . the base of the triangle is 16 cm . And we need to find the median .
We know that in a isosceles triangle
All perpendicular bisector , altitude and median concide with each other.This means that the base will be divided into two equal parts For Figure refer to attachment .
Using Pythagoras Theorem :-⇒ BM² + AM² = AB²
⇒ (17cm)² = (8cm)² + AM²
⇒ 289 cm² = 64cm² + AM²
⇒ AM² = 289 cm² - 64 cm²
⇒ AM² = 225 cm²
⇒ AM = √225 cm²
⇒ AM = 15 cm .
Hence the measure of median is 15 cm .I need number 4 solved please

Answer:
26/35
Step-by-step explanation:
6/35+4/7
you need to make the second fraction have the same denominator
to do this, you need to do 7 times 5 to make 35
times the numerator by the same
this would mean:

The entry ticket to a local football game costs $10 for an adult and $5 for a child. A group of 100 people paid an entry fee of $710. How many adults and how many children were there in this group?
Answer: Adults = 58
Children = 42
Step-by-step explanation:
Let adults be denoted as a
Let Children be denoted as c
a + c = 100 ...... i
10a + 5c = 710 ...... ii
Multiply I by 5
Multiply ii by 1
5a + 5c = 500 ...... iii
10a + 5c = 710 ...... iv
Subtract iii from iv
5a = 210
a = 210/5
a = 42
Since a + c = 100
c = 100 - 42 = 58.
Adults = 58
Children = 42

6 x 1 +2=8
At n=2
6 x 2 +2 = 14
At n=3
6 x 3 +2 = 20
At n=4
6 x 4 +2 = 26
Does 1.414213562 round to the nearest tenth.
Hey there!
Yes, it does. It rounds to 1.4.
1.414213562 rounded to the nearest tenth is 1.4, since the next number is less than 5, the 4 stays the same. If the next number was a 5 or greater, it would be 1.5, instead of 1.4.
Hope this helps! Good luck and have great day!

HELP ! PROBABILITY !
Easy
Answer:
The probability is zero
Step-by-step explanation:
Probability
There are 3 white counters and 2 black counters in a bag. One of them is chosen at random.
It's required to calculate the probability that a green counter has been chosen.
The probability of an outcome is defined as the frequency of the number of times the outcome occurs relative to the number of times that it could have occurred.
The equation to calculate the probability is:
[tex]P=\frac{f}{n}[/tex]
Where f is the number of favorable cases and n is the total cases.
Since there are no green counters in the bag, it's impossible to choose a green counter, thus f=0 out of n=5 total cases:
[tex]P=\frac{0}{5}[/tex]
P = 0
We have put the cross in the mark 0 on the probability scale below
