Answer:
It's carbon tetrachloride.
It's Dinitrogen Pentoxide.
Hope this helped!!!
Answer:
D. Using the new pesticide produces bigger tomatoes than using the
old pesticide.
Explanation:
This hypothesis is best to test for the effect of the new pesticide on the tomato plant.
A pesticide is chemical formulation used to kill pests of farm crops.
Pests prevents the healthy and proper growth of plants thereby resulting in poor yield on the farm.
For the farmer to ascertain the effect of the pesticide on his farm crop, he must compare the yield of his produce. Some tomato might grow well but would not bear good fruit. If the farmer focuses on the fruit produced, he would have derieved a good hypothesis in his experiment.
Oh shoot I don’t k is if I’d correct on this
Answer:
A = 356 cm²
Explanation:
In this case, you need to use the formula to calculate the area of regular solid.
This is the following expression:
S = 2LH + 2LW + 2WH
Where:
L: length
W: Width
H: Height
But we do not know the height of the solid. We should calculate it with the given data first:
1424 = 2*28*H + 2*28*16 + 2*16*H
1424 = 56H + 896 + 32H
1424 - 896 = 88H
H = 528/88
<em>H = 6 cm</em>
Now that we know the height we can calculate the area of the other solid. In the other solid the length has been reduced to half, so I will assume that the Width and height is also reduced to half.
L2 = 14 cm
W2 = 8 cm
H2 = 3 cm
Replacing we have:
S = (2*14*3) + (2*14*8) + (2*8*3)
<u>S = 356 cm²</u>
<u>And this should be the total surface area, assuming the width and height is reduced to half too.</u>
If you don't assume it's reduced to half, then use the original values of Width and Height. Doing so, the Surface would be:
S = (2*14*6) + (2*14*16) + (2*6*16)
S = 808 cm²
