You put $500 in a savings account. The account earns $20 simple interest in 6 months. What is the annual interest rate? Write your answer as a percent
Answer:
8%
Step-by-step explanation:
For simple interest, we use the equation I = PRT, where I is the interest earned, P is the principal/amount invested, R is the rate as a decimal, not percentage, and T is the time in years.
For this problem, we have to use 0.5 for T, because 6 months is 1/2 a year.
20 = (500)(r)(0.5)
20 = 250r
r = 0.08 = 8%

A number is divided by 3 and decreased by 5 is 6. What is the number???
Answer:
Given : x/3-5=6
answer = 23
Step-by-step explanation:
x-5=6*3
x-5=18
x=18+5
x=23
Answer:
33
Step-by-step explanation:
let the number be n , then the number divided by 3 is [tex]\frac{n}{3}[/tex] and decreased by 5
[tex]\frac{n}{3}[/tex] - 5 = 6 ( add 5 to both sides )
[tex]\frac{n}{3}[/tex] = 11 ( multiply both sides by 3 )
n = 33
The number is 33

5x + 2y = 15
y = -3x + 4
Answer:
5x+2y=15
y=-3x+4
Substituting the value of y in the first equation..
5x+2(-3x+4)=15
5x-6x+8=15
x = -7
So, y = -3(-7)+4
y = 25

Answer:
[tex]P_1=11.7\\P_2=15.21\\P_n=9\cdot1.3^n\\P_{10}\approx124.07[/tex]
Step-by-step explanation:
An exponential function can be written in the form ...
y = a·b^x
where x is the independent variable, b is the common ratio, and 'a' is the initial value (when x=0). The "common ratio" is the ratio of each term to the one before. For example, b = P₁/P₀.
Here, you are told the initial value (P₀) is a=9, and the common ratio is b=1.3. The independent variable is given as n, so your population formula is ...
P(n) = 9·1.3^n
__
You are asked for values when n = 1, 2, and 10. Since you know the common ratio, you can simply multiply P₀ by 1.3 to get P₁:
P₁ = 1.3·P₀ = 1.3·9 = 11.7
Similarly, ...
P₂ = 1.3·P₁ = 1.3·11.7 = 15.21
__
You could continue up to P₁₀, but it is easier to use a calculator to evaluate the exponential function.
P(10) = 9·1.3¹⁰ ≈ 124.07

Many questions in research can be expressed as two competing statements about the population parameter. These two statements are called the null and the alternative hypotheses. Usually, the researcher hopes the sample evidence will be in favor of the alternative hypothesis, the new theory. It is important to be able to state the theories that are being put to a test. For the scenario below, write out the hypotheses to be put to the test and define the parameter of interest in context of the problem.
Suppose that 70% of all faculty members at large public universities in the US use iClickers in their classrooms. We would like to assess if the proportion of faculty members at UM who use iClickers in the classroom is less than the stated rate.

Can someone tell me what x and y would be
Step-by-step explanation:
20°+120°+I°=180°
I=40°
using sine rule,
I/sin I=x/sinX
12/sin40=x/sin20
x=12sin20/sin40
x=6.4
using similarly and enlargement,
we have, cw/cp=y/120
8/12=y/120
y=80°
A farmer recently sold a large plot of land. The sale decreased his total acreage by 6%. Let v be the original acreage. Find two equivalent expressions that will give the new acreage. Use the expressions to describe two ways to find the new acreage. Name two expressions that would give the new acreage. (A)0.06v
(B)6v
(C)v-6v
(D)0.94v-0.06v
(E)v-0.06v
(F)0.94v
Answer:
[tex]v - 0.06v[/tex] and [tex]0.94v[/tex]
Step-by-step explanation:
Given
[tex]Acreage = v[/tex]
[tex]Decrement = 6\%[/tex]
Required
Determine the new acreage
Because a reduction occur, the new acreage can be calculated using:
[tex]New = Acreage - Decrement * Avreage[/tex]
[tex]New = v - 6\% * v[/tex]
[tex]New = v - 0.06 * v[/tex]
[tex]New = v - 0.06v[/tex] ------ (1)
Evaluate the expression
[tex]New = 0.94v[/tex] ---- (2)

Given:
The rate of interest on three accounts are 7%, 8%, 9%.
She has twice as much money invested at 8% as she does in 7%.
She has three times as much at 9% as she has at 7%.
Total interest for the year is $150.
To find:
Amount invested on each rate.
Solution:
Suppose x be the amount invested at 7%. Then,
The amount invested at 8% = 2x
The amount invested at 9% = 3x
Total interest for the year is $150.
[tex]x\times \dfrac{7}{100}+2x\times \dfrac{8}{100}+3x\times \dfrac{9}{100}=150[/tex]
Multiplying both sides by 100, we get
[tex]7x+16x+27x=15000[/tex]
[tex]50x=15000[/tex]
Dividing both sides by 50, we get
[tex]x=\dfrac{15000}{50}[/tex]
[tex]x=300[/tex]
So, the amount invested at 7% is [tex]300[/tex].
The amount invested at 8% is
[tex]2(300)=600[/tex]
The amount invested at 9% is
[tex]3(300)=900[/tex]
Hence, the stockbroker invested $300 at 7%, $600 at 8%, and $900 at 9%.

9x² - 25
Would this be correct ladies and gents
Answer:
You can use the useful mnemonic: SOH CAH TOA to determine what function to use. Since we have information about the hypotenuse (H) and opposite (O), we should use sine (S) for "SOH".
So yes, sine would be correct.
