At a football game Jasmine bought a soft pretzel for $2.25 in a bottle of water for $1.50 she paid with a $5 bill how much thing

andrew11 [14]

Answer:

$1.25.

Step-by-step explanation:

We have been given that at a football game Jasmine bought a soft pretzel for $2.25 in a bottle of water for $1.50 she paid with a $5 bill.

First of all let us find how much Jasmine spent on soft pretzel and water bottle by adding the cost of both items.

$\text{Total amount spent on both items}=2.25+1.50$

$\text{Total amount spent on both items}=3.75$

To find the amount that Jasmine will get as a change we will subtract the amount spent on both items from 5.

$\text{Amount of change that Jasmine will get}=5-3.75$

$\text{Amount of change that Jasmine will get}=1.25$

Therefore, Jasmine will get $1.25 back as change.

Answer:

The answer is 10⁴ × 4⁵.

Step-by-step explanation:

First, you can seperate the fraction :

$\frac{ {10}^{4} \times {4}^{10} }{ {4}^{5} }$

$= {10}^{4} \times \frac{ {4}^{10} }{ {4}^{5} }$

Next, you have to apply Indices law :

${a}^{m} \div {a}^{n} = {a}^{m - n}$

So for this question :

${10}^{4} \times \frac{ {4}^{10} }{ {4}^{5} }$

$= {10}^{4} \times {4}^{10 - 5}$

$= {10}^{4} \times {4}^{5}$
