Answer:
The probability that a point randomly chose in the rectangle is in the triangle is 
, so the answer would be A
Step-by-step explanation:
To find the probability of a random point being in the triangle, we must find the area of the triangle and the area of the rectangle.
The area of the rectangle can be found by multiplying the width by the height, so the equation would be
The area of the the triangle can be found by the formula 
This means that the equation would look like
Now that we have both the area of the triangle and the rectangle, we can create a ration of the area of the triangle to that of the rectangle. It would look like this
This would simplify to
Answer:
850 x 0.3 /1.7 = 150ltr
We round up to 200ltr. for 1sf
Step-by-step explanation:
Answer:
(a). 2.251 cm
, 2.349 cm, 2.295 cm
(b). 0.023 meters.
Step-by-step explanation:
(a). We are asked to to choose the options that shows the actual measurement of the rainfall.
Since the rounded figure is 2.3 cm, this means that either the tenths digit is 3 with hundredths digit less than 5, or tenths digit is 2 with hundredths digit greater than or equal to 5.
Let us check our given choices one by one.
Therefore, the correct choices are 2.251 cm
, 2.349 cm and 2.295 cm.
(b) We know that 1 cm equals 0.01 meters.
To convert 2.3 cm to meters, we will multiply 2.3 by 0.01.
Therefore, the rounded measurement of rain would be 0.023 meters.
Answer:
0
Step-by-step explanation:
Substitute x = - 3 into the expression
x² + 4x + 3
= (- 3)² + 4(- 3) + 3
= 9 - 12 + 3
= 0
