Answer:
71 %
Step-by-step explanation:
Paper 1 :
65% of 120 = 0.65 X 120 = 78
Paper 2 :
80% of 80 = 0.8 X 80 = 64
Total Percentage:
Add the two scores 78 + 64 = 142
Add the what it was out of 120 + 80 = 200
Use (Score / Total marks available) X 100
(142 / 200) X 100 = 71
Answer:
3
Step-by-step explanation:
Pythagorean Theorem: a²+b²=c²
You can fill in the numbers you know: a²+4²=5²
(Hypotenuse must be side c)
Square those numbers and you have: a²+16=25
Subtract 16 from both sides: a²=9
Square root both sides and you get: a=3
Answer:
length and width = 40 and 10 ft.
Step-by-step explanation:
The perimeter of a rectangular toddler play area is 100 feet.
Perimeter = 2(length + width)
Let the width = w
The length is 10 feet more than 3 times the width. Length = 10+(3w)
now put the values
100 = 2(10+3w + w)
100 = 2w + 20 + 6w
100 = (2w + 6w) + 20
100 = 8w + 20
8w = 100 - 20
w =
w = 10 feet.
Now Length = 10+ (3w)
= 10+( 3 × 10)
= 10 + 30
= 40 feet
Therefore, length = 40 feet and width = 10 feet
Answer:
31.25 percent increase
Step-by-step explanation:
To find the percent increase, we take
percent increase = (new - original)/new * 100 percent
= (420-320)/320 * 100 percent
100/320 * 100 percent
.3125 * 100 percent
31.25 percent increase
