The army bus has 12 seats on one side. Two soldiers can sit in each seat. If five seats are reserved for equipment, how many bus

marissa [1.9K]

Answer:

80 buses will be required for 1120 soldiers.

Step-by-step explanation:

Given:

Number of seats on One side = 12 seats.

Now Given:

five seats are reserved for equipment.

So we can say that;

Number of seats used by soldiers = $12-5=7\ seats$

Number of soldiers on Each seat =2

So we will now find number of soldiers on each bus.

number of soldiers on each bus is equal to Number of seats used by soldiers multiplied by Number of soldiers on Each seat.

framing in equation form we get;

number of soldiers on each bus = $7\times2 = 14\ soldiers$

Now we know that;

For 14 soldiers = 1 bus

So 1120 soldiers = Number of buses required for 1120 soldiers.

By Using Unitary method we get;

Number of buses required for 1120 soldiers = $\frac{1120}{14} =80$

Hence 80 buses will be required for 1120 soldiers.

If 10^2y = 25, then 10^-y equals: (a) -1/5 (b) 1/625 (c) 1/50 (d) 1/25 (e) 1/5

Gemiola [76]

<h3>given:</h3>

$10 ^{2y} = 25$

${10}^{y} = .......$

<h3>solution:</h3>

$10 ^{2y} = 25$

$(10y {)}^{2} = {5}^{2}$

$10y = 5$

$\frac{1}{ {10}^{y} } = \frac{1}{5}$

${10}^{ - y} = \frac{1}{5}$

therefore, the correct answer is option E.

1 and 3/4 divided by -21

Over [174]

Let's firstly convert the mixed fractions to "improper", and then divide,

$\bf \stackrel{mixed}{1\frac{3}{4}}\implies \cfrac{1\cdot 4+3}{4}\implies \stackrel{improper}{\cfrac{7}{4}}
\\\\\\
\cfrac{7}{4}\div -21\implies \cfrac{7}{4}\div \cfrac{-21}{1}\implies \cfrac{7}{4}\cdot \cfrac{1}{-21}\implies \cfrac{7}{-84}\implies \stackrel{simplified}{-\cfrac{1}{12}}$
