Can someone explain these questions to me, especially the last one please.

Firlakuza [10]

Answer:

Step-by-step explanation:

A is 0.5 x 10 because the thickness of the sheets is 0.5 and there are ten sheets stacked together that thickness so how thick is the pile.

for B it is the answer of A plus one more sheet which is ( answer for A) + 0.5

for c just add another sheet on all sides wich is + 0.5 for each side and when you get that add that number to answer B and that it.

If an angle of a parallelogram is two-third of

balandron [24]

Answer:

We know that in a parallelogram two opposite angles are equal -

$\\ \implies \sf \: 2x + 2y = 360 {}^{ \circ} \\ \\ \\ \implies \sf \: x + y = 180 {}^{ \circ} \qquad \quad \: (i) \\$

Given - 

angle x is equal to the two - third of it's adjacent angle y.

$\\ \implies \sf \: x = \frac{2}{3} y \\ \\ \\ \implies \sf \frac{x}{2} = \frac{y}{3} = k \\ \\ \\ \qquad \sf \small \underline{ x = 2k \: \: \& \: \: y = 3k} \\$

Now, by using equation (1) :

$\\ \implies \sf \: 2k + 3k = 180 \\ \\ \\ \implies \sf \: 5k = 180 \\ \\ \\ \implies \sf \: k = \frac{180}{5} \\ \\ \\ \large{ \boxed{ \sf{k = {36}^{ \circ} }}} \\$

Now, by putting the value of k in x and y. 

x = 2k = 2 × 36 = 72°
y = 3k = 3 × 36 = 108°

Therefore, the right option and smallest angle is b) 72°.

A can contained 5.5 ounces of tuna. Joey used 2.88 ounces of the tuna to make a sandwich. To find the amount of tuna remaining i

Veseljchak [2.6K]

Answer:

Yes

Step-by-step explanation:

A full can of tuna has a certain amount in it, if a portion is removed from the can it is therefore subtracted from the total amount. This means that Joey's work is correct and the tuna can would have

5.5 oz - 2.88 oz = 2.62 oz

The best way to tell if his work is correct would be to weigh the remaining tuna in the can and see if it matches Joey's answer.
