Answer:
angle 1 and angle 4 are supplementary because it is exterior alternate angle and sum of alternate exterior angle is always 180 degree(supplementary)
Step-by-step explanation:
Answer:
Volume of a cuboid or rectangular tank = side × side × side
or
volume of a cuboid or rectangular tank = length× width × height
volume of the rectangular tank = 76 × 50 × 40
volume of the rectangular tank = 152000cm³
Therefore the rectangular tank can hold 152000cm³ litres of water
Answer:
14km
Explanation
11km + 11km = 22km is the sum of both the width.
If you want to find the length than minus the perimeter with 22.
50km - 22km = 28km is the sum of both the length.
To know only one side of the length, divide it by 2.
28km/2 = 14km is the length
Answer:
17/20 or 0.85
Step-by-step explanation:
out of 20 hammers 17 are not large so the probability is 0.85
Answer:
Alex can only draw a rectangle with an area of 11 cm²
The reason for the answer is that 11 is a prime number
Step-by-step explanation:
We are told that Alex is drawing rectangles with different areas on a centimeter grid, and he can draw 3 different rectangles with an area of 12 cm²
We have the minimum grid length of centimeters = 1 cm, since we assume that only integers can be used.
That is to say:
12 = 1 x 12
12 = 2 x 6
12 = 3 x 4
These are the 3 different rectangles with an area of 12 cm²
Now we have to find how many rectangles Alex could draw with an area of 11 cm²
11 = 1 x 11
Therefore, only one factorization is possible. Which means that you can only draw a rectangle with an area of 11 cm²
The reason for the answer is that 11 is a prime number, which means only the common factor of 1 and the number itself, that is, 11.
