Answer:
21
Step-by-step explanation:
84% of 25 is 21
The maximum score is 100%, 100÷25= 4, meaning each question was 4 points or 4% of the total grade 84÷4=21 .
Answer:
21 questions were correctly answered
Step-by-step explanation:
If one scores an 84% on a quiz, that means that as an expression out of 100, a person has gotten 84 correct. To find how much the 84% equates to, one must convert the percent to a decimal. This means that one must divide the 84 by 100. After doing so, multiply the result by the number of questions on the quiz. The value attained will be the number of questions answered correctly.
Convert percent to decimal:
84% / 100 = 0.84
Multiply by the number of questions to find the amount answered correctly:
25 * 0.84 = 21

Step-by-step explanation:
Answer:
#2 is 2^-9. #3 is 1/6^15. #4 is 10^8.
Step-by-step explanation:
Remember that with exponents, division is subtraction, and multiplcation is addition.
So for the first problem, 2^-5 / 2^4 is really:
2^-5-4
This is simply 2^-9 power.
Next we have (6^-3)^5. I dont mean to confuse you, so just remember. When, and ONLY when and exponent is INSIDE parentherse, can it be multplilied by another exponent that is OUTSIDE of the parenthesese. SO we can write this as:
6^-3*5
This equals:
6^-15
Which can further be simplyfied to:
1/6^15
Countinuing on we have 10^-12 / 10^-20. Since we are dividing, we subtract to exponenets. So we can write this as:
10^-12 - -20
This is just 10^8 power.
Hope this helps! :)
(2) please find the area please and thanks
Answer:
38.5
Step-by-step explanation:
Use the trapezoid area formula which is (a+b)h/2. We know that a=6, b=8 and h=5.5. Plugging it it to the formula, we get (6+8)*5.5/2 which is 38.5.

The numerator of the given fraction is 4 less than the denominator. If 5 is added to both numerator and denominator, the resulting fraction is equivalent to 5/7 . What is the original fraction?
Answer:
5/9
Step-by-step explanation:
Let the denominator be x and numerator be y.
Given, numerator is 4 less than denominator
=> y = x - 4 ...(1)
When 5 is added to both:
Numerator = y + 5 , and, denominator = x + 5
Now their ratio is 5/7.
=> (y + 5)/(x + 5) = 5/7
=> 7(y + 5) = 5(x + 5)
=> 7y + 35 = 5x + 25
=> 7y - 5x = 25 - 35
=> 7(x - 4) - 5x = -10 {y=x-4}
=> 7x - 28 - 5x = -10
=> 2x = 18
=> x = 9
Thus,
Fraction is y/x = (x-4)/x = (9-4)/9 = 5/9

If I asked you is 5 a solution to the equation p +13= 21, how would you determine whether or not 5 works?Plz help I'll mark brainliest Thxs
Answer:
All you have to do is replace p with 5, and see if it works. In this case it doesn't because 5+13 does not equal 21.
Answer:
Not a solution
Step-by-step explanation:
You would plug 5 into the equation where it says p. If 5+13=21, then it is a solution. If it equals to something different, then it is not a solution. In this case, it adds up to 18, making it not a solution.

Step-by-step explanation:
[tex] m\angle CBD = m\angle FBG[/tex]
(Vertical angles)
[tex] \because m\angle FBG = 35\degree [/tex]
[tex] \therefore m\angle CBD = 35\degree [/tex]

(Linear pair angles)
[tex] m\angle DBE +m\angle CBD + m\angle ABC = 180\degree [/tex]
[tex] m\angle DBE + 35\degree + 53\degree = 180\degree [/tex]

6x + 238= 3x + 178
Answer:
x = -20
Step-by-step explanation:
Answer:
x = -20
Step-by-step explanation:
6x + 238 = 3x + 178
Subtract 3x from both side
3x + 238 = 178
Subtract 238 from both side
3x = -60
Divide by 3
x = -20

In a company's first year in operation, it made an annual profit of \$333,500$333,500. The profit of the company increased at a constant 8% per year each year. How much profit would the company make over the course of its first 24 years of operation, ?
P × R × T ÷ 100
333,500 × 8% ×24 ÷ 100
64,032,000÷100
640,320
The amount of profit would the company make over the course of its first 24 years of operation should be $2,114,784.
Calculation of the amount of profit:Since annual profit is $333,500
The profit percentage should be likely 8%
And, the number of years should be 24
So, the amount of profit should be
[tex]= $333,500 * (1 + 0.08)^{24[/tex]
= $2,114,784
hence, The amount of profit would the company make over the course of its first 24 years of operation should be $2,114,784.
