Answer:
28 questions
Step-by-step explanation:
In the first 10 mins she answered 2/5 of 40 which is 16. The remaining amount is 24 questions and half of that is 12. So she answered 12 questions in 15 mins. Finally you add them to get 28 questions in 25 minutes.
Answer:
so x = 4 and x = -2/3
Step-by-step explanation:
Solve for x using the Master Product:
3x^2-10x-8=0
we see 3*(-8) = -24 and 2 * (-12) = -24 and 2 + -12 = -10
so 3x^2 + 2x - 12x - 8 = 0
x (3x + 2) -4 (3x + 2) = 0
(x - 4)(3x + 2) = 0
so x = 4 and x = -2/3
Answer:
This needs more information for it to be solved.
Step-by-step explanation:
Are there answer choices?
or a chart with specific information of the appropriate measurements that can be put into the equation to solve it?
I wish i could give you a proper answer, but without the numbers I can't answer this for you. I'm sorry.
Answer:
Percent (%)' means 'out of one hundred':
p% = p 'out of one hundred',
p% is read p 'percent',
p% = p/100 = p ÷ 100.
91% = 91/100 = 91 ÷ 100 = 0.91.
100% = 100/100 = 100 ÷ 100 = 1.
Decrease number by 91% of its value.
Percentage decrease = 91% × 843
New value = 843 - Percentage decrease
Calculate the New Value
New value =
843 - Percentage decrease =
843 - (91% × 843) =
843 - 91% × 843 =
(1 - 91%) × 843 =
(100% - 91%) × 843 =
9% × 843 =
9 ÷ 100 × 843 =
9 × 843 ÷ 100 =
7,587 ÷ 100 =
75.87
Calculate absolute change (actual difference)
Absolute change (actual difference) =
New value - 843 =
75.87 - 843 =
- 767.13
Proof.
Calculate percentage decrease:
Percentage decrease =
91% × 843 =
91 ÷ 100 × 843 =
91 × 843 ÷ 100 =
76,713 ÷ 100 =
767.13
Step-by-step explanation:
