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%

Solve |x–1| = 6x + 12
Answer:
[tex]x = - \frac{11}{7} [/tex]
Step-by-step explanation:
1) Break down the problem into these 2 equations.
[tex]x - 1 = 6x + 12[/tex]
[tex] - (x - 1) = 6x + 12[/tex]
2) Solve the first equation. x - 1 = 6x + 12
[tex]x = - \frac{13}{5} [/tex]
3) Solve the second equation: -( x - 1 ) = 6x + 12.
[tex]x = - \frac{11}{7} [/tex]
4) Collect all solution.
[tex]x = - \frac{13}{5}. - \frac{11}{7} [/tex]
5) Check solution.
When x=-\frac{13}{5}x=−513, the original equation |x-1|=6x+12∣x−1∣=6x+12 does not hold true.
When x=-\frac{13}{5}x=−513, the original equation |x-1|=6x+12∣x−1∣=6x+12 does not hold true.We will drop x=-\frac{13}{5}x=−513 from the solution set.
6) Simplify.
[tex]x = - \frac{11}{7} [/tex]
Therefor, the answer is x = - 11/7.
Cual es la ley que establece que la suma o producto de dos números reales no dependen del orden en que se presentan los factores en la multiplicación y los sumados en la aducción ?
Answer:
Conmutativa
Step-by-step explanation:
Propiedad conmutativa : El orden de los factores no varía el producto o la suma. Un ejemplo seria 3 x 10 da lo mismo que 10 x 3 que es 30.
Con la suma 3+ 5 es lo mismo que 5+3 que es 8.
Nada mas funciona con SUMA o MULTIPLICACION. Nunca en la resta.

can you help me with my math homework erica Turner please it's just like yesterday
Answer:
yup what´s your question I can try
Step-by-step explanation:
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.

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%.
In science class, the girl to boy ratio is 3 to 7.

Answer:
35 are boys and other are girl
Answer: 35 boys
Step-by-step explanation:
So we know the ratio of girls to boys for every 10 student is 3 girls to 7 boys from there we can multiply each number by 5 to give us a total of 50 students which would be 15 girls to 35 boys.
How do you which equation symbol to use?

Find the area of the shaded area using the given dimensions:
The shaded area is divided up into two triangles, each with a base of 2 cm and a height of 2 cm. Use the following equation to solve for area:
A = 1/2(bh)
A = 1/2(2 · 2)
A = 1/2(4) = 2 cm²
There are two triangles, therefore:
2 × 2 = 4 cm²
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°
