Answer:
The Volume, Area, and Surface Area can be found with division and multiplication. Like so: (1st question, start) = 12m divided by 6m which equals 2. That is the answer for the first one.
Step-by-step explanation:
Multiplication for finding Volume, and Division for finding Area, and Surface Area.
Answer:
<u><em>The error Vikam made:</em></u><u><em> He actually used the wrong expression to represent the area of the base of the given pyramid. </em></u>
Step-by-step explanation:
The surface area of the pyramid that is given = 4 * (0.5 * 34.2 * 28.4) + 34.2 * 34.2
Now, the Total area of it is = (2 * 0.5 * 36.5 * 25.6) + (2 * 0.5 * 37.8 * 16.2) + (25.6 * 16.2)
= (36.5 * 25.6) + (37.8 * 16.2) + (25.6 * 16.2)
1 cup = 128 grams
X cups = 96 grams
Cross multiply
128X = 1*96
X=96/128 cups = 6/8 = 3/4 cups.
If she has already added 1/2 cups, then she needs to add (3/4-1/2)=1/4 cup more sugar.
Also please remind her to do the calculations before adding ingredients to avoid ruining a recipe.
24.25 i think would be the answer
Answer:
252°
Step-by-step explanation:
In the figure attached, the diagram is shown. There, we can see that
∠DOB = ∠AOD + ∠AOC + ∠COB
Replacing with the equivalences: ∠DOB has a measure of 3.5y, the measure of ∠AOD is y, and ∠AOC + ∠COB measure 180°, we get:
3.5y = y + 180°
3.5y - y = 180°
2.5y = 180°
y = 180°/2.5
y = 72°
Therefore, ∠DOB = 3.5*72° = 252°
