Austin checks the temperature at 10:00 p.m. He notices if the temperature

Alecsey [184]

Answer:

A. t - 5 < 26°

Step-by-step explanation:

Record low temperature for that date = 26°

Temperature at 10:00 PM = t

A fall in temperature by 5° = t - 5

Thus, this is said would mean the record low temperature would be breaking at this point, meaning the new temperature low recorded will be less than 26°.

In mathematical expression, this is expressed as;

t - 5 < 26°

10. Which travels faster, a car that goes 200 miles in 2 hours, or a

umka21 [38]

<h2>Answer:</h2>

<em>Question 10. </em><u><em>The truck travels faster</em></u><em>.</em>

<em>Question 11. </em><u><em>The slug travels faster</em></u><em>.</em>

<h2>Step-by-step explanation:</h2>

<h2><u>Question 10.</u></h2>

<u />

<h3>1. Find the velocity of each vehicle.</h3>

$Speed=\frac{distance}{time}$

$Speed_{Car} =\frac{200(miles)}{2(hours)}=100mi/h. \\\\ Speed_{Truck} =\frac{300(miles)}{2.5(hours)} =120mi/h.\\ \\$

<h3>2. Compare the velocities.</h3>

$Speed_{Car} =100mi/h < Speed_{Truck} =120mi/h.$

<em>Hence, the trucks travels faster than the car.</em>

<h2><u>Question 11.</u></h2>

<em>Apply the same method as in question 10.</em>

<h3>1. Find the velocity of each body.</h3>

<em /> $Speed_{snail}=\frac{20(cm)}{(3 min)} =6.67cm/min.\\ \\Speed_{slug}=\frac{15(cm)}{(2 min)} =7.5cm/min.$

<h3>2. Compare the velocities.</h3>

$Speed_{snail}=\frac{20(cm)}{(3 min)} =6.67cm/min < Speed_{slug}=\frac{15(cm)}{(2 min)} =7.5cm/min.$

Hence, the slug travels faster.

You can work at most 20 hours next week. You need to earn at least $92 to cover you weekly expenses.Your dog- walking job pays $

Anna11 [10]

<h3><u>The system of linear inequalities to model the situation are:</u></h3>

$x+y\leq 20\\\\7.50x+6y\geq 92$

<em><u>Solution:</u></em>

Let "x" be the time spent in dog walking job

Let "y" be the time spent in car wash attendant

Given that,

<em><u>You can work at most 20 hours next week</u></em>

"at most" means "less than or equal to" 20

Therefore,

$x+y\leq 20 ---------- eqn 1$

Also given that,

Your dog- walking job pays $7.50 per hour

Your job as a car wash attendant pays $6 per hour

<em><u>You need to earn at least $92 to cover you weekly expenses</u></em>

"at least" means "greater than or equal to" 92

Thus, a inequality is framed as:

$7.50 \times x + 6 \times y \geq 92$

$7.50x+6y\geq 92 ------------ eqn 2$

Thus eqn 1 and eqn 2 is the system of linear inequalities to model the situation
