230-190=40
From 230 the decrease was 40
from 100 the decrease is 100 x 40 divided by 230
The percent decrease was 17,39 about 17,4
So the correct answer is B
The answer is 8.
Ratio is a relationship among two numbers representing how many times the first number contains the second. The tip with ratios is to constantly multiply or divide the numbers by the same value.
When you multiply each number by four the sum will be 28.
2 x 4 = 8
5 x 4 = 20
The total is 28.
Answer:
Total amount earned after 25 years=$27,897.16
Step-by-step explanation:
Step 1: Express formula for calculating total amount
The total amount after 25 years can be expressed as;
A=P(1+r)^n
where;
A=total amount after 25 years
P=principal amount
r=annual interest rate
n=number of years
Step 2: Substitute values in the expression
In our case;
P=$6,500
r=6%=6/100=0.06
n=25 years
replacing in the original expression;
A=6,500(1+0.06)^25
A=27,897.16
Total amount earned after 25 years=$27,897.16
Let f(x) = ax³ + 9x² + 4x – 10
g(x) = 0⇒x - 3 = 0
⇒ x = 0 + 3
⇒ x = 3
On dividing f(x) by x - 3, it leaves a remainder 5.
Now keeping, f(3) = 5
⇒a(3)³ + 9(3)² + 4(3) - 10 = 5
⇒ a × 27 + 9 × 9 + 4 × 3 - 10 = 5
⇒ 27a + 81 + 12 - 10 = 5
⇒ 81 + 12 - 10 - 5 = 27a
⇒ 81 + 12 - 15 = 27a
⇒ 93 - 15 = 27a
⇒ 78 = 27a
⇒ a = 27/78
⇒ a = 0.3461
