Answer:
A
Step-by-step explanation:
D) 8.17 x 10^8
910000000 - 93000000 = 817000000
817000000 ---> 8.17 x 10^8
Total flour used = Sum of all the cups
Total = 2 cups + 0.5 cups + 1.75 cups
= 4.25 cups of flour
4.25 cups of flour was used.
Hope this explains it.
Answer:
9.2 (1DP)
Step-by-step explanation:
- First you do 10^2 which is 10 X 10 = 100
- Then you do 4^2 which is 4 X 4 = 16
- Then you do 100 - 16. The way Ive learnt it is that if the hypotenuse isn't the one you have to find then minus of it it is then plus. So 100 - 16 = 84
- A^2 + B^2 = C^2 84 is C^2 meaning now you have to square root it
- Square root of 84 is 9.2 to 1 DP
Answer:
44,39 in
Step-by-step explanation:
To find the space diagonal (whatever it's called in English) you begin looking at the bottom of the box. We want to know the diagonal since the diagonal is one of the sides of the other triangle.
To do this we can start by using trigonometry. (SOH-CAH-TOA)
We need to use Sin t. (Since we wanna know the hypothenuse and we have the opposite.)
So...
Sin(40) = 24 in ÷ <em>h</em>
Then we need to actually be able to calculate this, which we will be able to do if we multiply with h on both sides.
hSin(40) = 24 in
Like that. And now we can divide both sides with Sin(40). So we calculate 24 in devided by Sin(40).
h = 24 in ÷ Sin(40) = 37,34 in
Okay so now we now the diagonal, 37,34 in. Now we can use Pythagorean theorem. (2a+2b=2c and c = square root of (2a+2b))
37,34 in^(2) + 24 in^(2) = 1970,28
And now we take the square root of 1970,28.
Which is about 44,39 in.
