Answer:
$90.00
Step-by-step explanation:
40% of What is 36?
40/4 = 10 (10%)
36/4 = 9 (9 is 10% of the answer we are looking for)
Multiply both answers (9 and 10) by each other.
You get 90
Answer:
The correct answer is 15 cm.
Step-by-step explanation:
Let the width of the required poster be a cm.
We need to have a 6 cm margin at the top and a 4 cm margin at the bottom. Thus total margin combining top and bottom is 10 cm.
Similarly total margin combining both the sides is (4+4=) 8 cm.
So the required printing area of the poster is given by {( a-10 ) × ( a - 8) } 
This area is equal to 125 as per as the given problem.
∴ (a - 10) × (a - 8) = 125
⇒ 
- 18 a +80 -125 =0
⇒ - 18 a -45 = 0
⇒ (a-15) (a-3) = 0
By law of trichotomy the possible values of a are 15 and 3.
But a=3 is absurd as a 
4.
Thus the required answer is 15 cm.
Answer:
The best option is c
Step-by-step explanation:
The same textbooks contains a total of 848 pages . Which represent the total number of pages , y , of any number of the same textbooks , x.
The number of same text book = x
Each of this textbook contains a total of 848 pages .
The total number of pages can be computed as
y = 848x
for 4 same text book
y = 848 × 4 = 3392 pages
for 3 same text book
y = 848 × 3= 2544 pages
for 7 same text book
y = 848 × 7 = 5936 pages
for 8 same text book
y = 848 × 8 = 6784 pages
for 11 same text book
y = 848 × 11 = 9328 pages
Hi There!
Dori leaves her house at 12pm.
50 steps per minute until 12:20pm.
Dori has a 20 minute advantage over Malory, find the amount of steps she is ahead by,
12 - 12:20pm. steps = 20 minutes = 20 x 50 = 1000 steps
Malory leaves her house at 12:20pm.
Walks 90 steps per minute.
12:20 - 12:30 pm. = 10 minutes = 10 x 90 = 900
Dori 12:20 - 12:30pm. = 10 minutes = 10 x 50 = 500
500 + 1000 = 1500
Mallory 12:30 - 12:40 = 10 minutes = 10 x 90 = 900
900 + 900 = 1800
Dori 12:30 - 12:45pm. = 15 minutes = 15 x 50 = 500
1750 + 500 = 2250
Mallory 12:40 - 12:45pm. = 5 minutes = 10 x 90 = 900
450 + 1800 = 2250
Answer: they have the same number steps at 12:45 p.m.
Hope This Helps :)
The answer is 37!
(-8)^2 - 5(-8) + 7 = 111
(111)(1/3) = 37
