4^-3 would be 1/64 since you flip the 4 over when you have a negative power and 4^5 would be 1024 (4 x 4 x 4 x 4 x 4) so your final answer would be 16
because you have to divide 1024 by 64
Answer:
7
Step-by-step explanation:
If each pack of green beans makes 12 bowls of soup then it would take 7 packs to make 84. 84/12=7
Answer:
B
Step-by-step explanation:
make sure calculator is in degrees mode and insert equation to get -7.5
Let the time taken by computer for virus scan be, 'x' days
We are given that Computer A runs a virus scan in every 2.75 days and Computer B runs a virus scan in every 3.5 days.
<h3>Amount of work done by computer A⤵️</h3>
Amount of work done in one day = 
Amount of work done in x days = 
<h3>Amount of work done by Computer B⤵️</h3>
Amount of work done in one day = 
Amount of work done in x days = 
Since, They are doing the same work the amount of work done is 1.

Solve for x ~






➪ <em>Thus, the time taken when both computers run a virus scan at the same time again is, 1.54 days</em>
In one hour the plane will cover a distance of 1238 km.
<h3>
What is a linear equation?</h3>
- A linear equation has one or two variables.
- No variable in a linear equation is raised to a power greater than 1.
- No variable is used as the denominator of a fraction.
- A linear equation is defined as an equation that is written in the form of ax+by=c.
- When solving the system of linear equations, we will get the values of the variable, which is called the solution of a linear equation.
solving this we will get the valve of Y is x is given.
calculation:-
today distance = 9904 km.
total time is taken = 8 hours.
∴total distance covered in one hour = 9904/8
= 1238 km.
