A truck driver drove 48 miles in 45 minutes.At this rate,how many miles can the truck drive in one hour?

murzikaleks [220]

Answer:

64 miles

Step-by-step explanation:

Number of miles driven in 45 minutes = 48 miles

We need to find how many miles will the truck drive drive in one hour. Since the rate is the same, the distance covered in each minute remains the same.

Number of miles driven in 1 minute = miles

Since, 1 hour = 60 minutes, we can write:

The number of miles driven in 1 hour (60 minutes) = miles

This means the truck driver can drive 64 miles in an hour.

HOPE THIS HELPS! :)

Given g(x)=Squareroot x-4 and h(x)=2x-8, what is g(h(10))

yan [13]

Answer:

$g(h(10)) = 2\sqrt 2$

Step-by-step explanation:

Given

$g(x) = \sqrt {x - 4$

$h(x) = 2x - 8$

Required

$g(h(10))$

First, calculate $g(h(x))$

We have:

$g(x) = \sqrt {x - 4$

This gives:

$g(h(x)) = \sqrt {h(x) - 4$

Substitute $h(x) = 2x - 8$

$g(h(x)) = \sqrt {2x - 8 - 4$

$g(h(x)) = \sqrt {2x - 12$

Substitute $x = 10$

$g(h(10)) = \sqrt {2*10 - 12$

$g(h(10)) = \sqrt {20 - 12$

$g(h(10)) = \sqrt {8\\$

Split

$g(h(10)) = \sqrt {4} * \sqrt 2$

This gives

$g(h(10)) = 2\sqrt 2$

Rewrite in mathematical language. Every negative integer J is less than or equal to its inverse.

Luda [366]

Answer:

$-J \leq J$

Step-by-step explanation:

Given

Negative integer J

Required

Represent as an inequality of its inverse

The question didn't state if it's additive inverse or multiplicative inverse;

<em>Since the question has to do with negation, I'll assume it's an additive inverse</em>

The inverse of -J is +J

To represent as an inequality (less than or equal), we have:

$-J \leq +J$

Solving further, it gives

$-J \leq J$
