Answer:
2 61/64 m2
Step-by-step explanation:
V = length * width * height
2.25 * 7/8 * 1.50
V = 2 61/64 m2
* = multiplication symbol
V = Volume
Answer: 3, 5, 7
Step-by-step explanation:
There is a "trick" to determine divisibility by 3: if the sum of the digits is divisible by 3, the number is divisible by 3.
3 + 1 + 5 = 9 which is a multiple of 3, so 315 is divisible by 3.
It works for 9 also. since the sum of the digits is 9, 315 is divisible by 9.
Divisibility by 5: any number that has the units digit 5 or 0 is divisible by 5.
For 7, I just tried it 315÷7= 45
Only even numbers are divisible by 2.
If a 3-digit number is divisible by 11, the middle digit will be the sum of the first and last digits. (That is not the case for 315) But 385 is divisible by 11, also 495, 253, and many others you can try for fun.
Answer:
The answer to your question is At = 48 + 36
Step-by-step explanation:
Area = Area of the base + Lateral area
a) Area of the base
Area = length x height / 2
length = 12
height² = 12² - 6²
= 144 - 36
= 108
height = 
= 6
Area = 12 x 6
= 36
b) Lateral area
height² = 10² - 6²
= 100 - 36
= 64
height = 8
Area = 12 x 8/2
= 48
c) Total area
At = 48 + 36
Answer:
She sneezed for 138.286 weeks in a row. You need days of week to create a proper conversion.
Step-by-step explanation:
There are 7 days in a week. There are 978 days shown.
You can depict it as this:
978 = 7x; x is the amount of weeks.
Divide both sides by 7
138.285714 = x
Round to three decimals
x = 138.286
It means break them down so u get just one factor
