Answer:
35 times
Step-by-step explanation:
7/10 * 50 = 35
Use the formula for the area of a triangle.
Simplify:
Divide 2 to both sides:
Answer: 1120
Step-by-step explanation:
Since 12 out of every 180 frogs in the popluation have spots on their back, this means that (180 - 12) = 168 do not have spot on their back. This can be represented in a fraction as:.= 168/180 = 14 / 15
With a study of a population of 1,200 frogs, the number of frogs that do not have a spots on their back will be:
= 14/15 × 1200
= 1120
Answer:
The number of boys is 34 And The number of girls is 16
Step-by-step explanation:
Given as :
Total number of boys and girls = 50
Total amount to be divided between boys and girls = Rs 41
The amount given to each boys = 90 paise = Rs 0.9
The amount given to each girls = 65 paise = Rs 0.65
Let The number of Boys = B
The numbers of girls = G
So, According to question
0.9 B + 0.65 G = Rs 41
And B + G = 50
Or, 0.9 B + 0.65 G = Rs 41 .......1
And 0.9 B + 0.9 G = 45 ......2
Now, ( 0.9 B + 0.9 G ) - ( 0.9 B + 0.65 G ) = 45 - 41
Or, 0.25 G = 4
∴ G = = 16
And The number of boys = B = 50 - G = 50 - 16 = 34
Hence The number of boys is 34 And The number of girls is 16 Answer
Q -------------R------------S
suppose this is your line,
R is the mid point
and it's given that
QR = 2x
and
RS = x+3
as R is the mid point of QS
so,
QR = RS
then,
2x = x + 3
2x - x =3
x = 3
as,
it's given that RS = x + 3
then,
RS = 3 + 3
= 6 units.
