What number increased by ¼ of itself is equal to 30?
Answer:
x = 24
Step-by-step explanation:
let x be the number we want to determine its value
The statement x increased by ¼ of itself is equal to 30
is equivalent to :
[tex]x + \frac{x}{4}=30\\\\then[/tex]
[tex]\frac{4x+x}{4} = 30\\\\then[/tex]
[tex]\frac{5x}{4} = 30\\\\then[/tex]
5x = 4× 30
then
5x = 120
then
x = 120/5
then
x = 24
Upon review of production results, it was determined that 130 pieces out of 3,500 were "out of spec." What percent of the production was "out of spec"?
A. 0.03 percent .
B. 3.71 percent .
C. 30 percent
D. 37.1 percent
Answer:
Option B
Step-by-step explanation:
Given:
130 pieces of 3500 were out of specTo determine the percentage of the production was out of spec, we need to use the percentage formula (x/y × 100).
[tex]\implies \dfrac{x}{y} \times 100[/tex]
The value of "x" is the the number of pieces that were out of spec and the value of "y" is the total pieces in the production results.
[tex]\implies \dfrac{130}{3500} \times 100[/tex]
Simplify the expression to determine the percentage of the pieces that were out of spec.
[tex]\implies \dfrac{13000}{3500}[/tex]
[tex]\implies \dfrac{130}{35} = \dfrac{130 \div 5}{35 \div 5} = \dfrac{26}{7} = 3.714... \%[/tex]
When the percentage is estimated to nearest hundredth, we get 3.71%
(Option B)
Answer:
B) 3.71%
Step-by-step explanation:
[tex]\textsf{130 out of 3500}\sf =\dfrac{130}{3500}[/tex]
To convert to a percentage, multiply by 100:
[tex]\implies \sf \dfrac{130}{3500} \times 100\%=0.03714.. \times 100\%=3.71\%[/tex]

What is the explicit formula for this geometric sequence?
8, 4, 2, 1, …
Answer:
[tex]a_{n} = \frac{8}{2^{n-1} }[/tex]
Step-by-step explanation:
A geometric sequence has a constant ratio (r) and is defined by:
[tex]a_n=a_1r^{n-1}[/tex]
Since the first value is 8, [tex]a_{1}[/tex] = 8.
[tex]a_n=8r^{n-1}[/tex]
We can also see that a_n is double that of the next value in the sequence [tex](a_{n} = 2a_{n+1}})[/tex], hence r = 1/2
[tex]a_n=8\left(\frac{1}{2}\right)^{n-1}[/tex] or
[tex]a_{n} = \frac{8}{2^{n-1} }[/tex]

Lisa cut out 36 paper snowflakes to decorate her room.
Then her brother gave her 28 paper snowflakes that he had made.
If she chooses to use only half of the snowflakes to decorate, how many will
she have left over?
Answer: 32
Step-by-step explanation:
We know that the original number of paper snowflakes was 36, plus 28 given by her brother. The new total would be 64 paper snowflakes and she only uses half of the paper snowflakes. The answer would be 32.

what value would you put
A. 0.0063
B. 0.00525
C. 0.525
D. 6.3
The value that would be put for r is; 0.063
Interest ratesWe are given the monthly payment formula for present value as;
M = (Pr(1 + r)ⁿ)/(1 - r) - 1
Where;
P is Present Value
r is interest rate
n is number of times compounded
Now, we are told the interest rate is given as 6.3% and so we can write that; r = 6.3/100 = 0.063

What is the value of a if 3(a − 5) = 2(a +5)?
Answer:
a= 25
Step-by-step explanation:
STEPS FOR SOLVING LINEAR EQUATION
3(a−5)=2(a+5)
Use the distributive property to multiply 3 by a−5.
3a−15=2(a+5)
Use the distributive property to multiply 2 by a+5.
3a−15=2a+10
Subtract 2a from both sides.
3a−15−2a=10
Combine 3a and −2a to get a.
a−15=10
Add 15 to both sides.
a=10+15
Add 10 and 15 to get 25.
a=25

color. Which statement is not true?
Answer:
C. The likelihood of having brown eyes is 35%
Step-by-step explanation:
Add the total number of people, which gives you 50.
To find the percent of brown-eyed people out of 50, divide 35 by 50, then multiply the result (0.7) by 100 to get 70%.
70% of people are brown-eyed, thus, C is a false statement.
