Jared and Pedro walk 1 mile in about 15 minutes. They can keep up pace for several hours. About how far they walk in 65 minutes

VladimirAG [237]

<h2><u>Answer:</u></h2>

Jared and Pedro walked a total of <u>4.3 miles</u>

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

The equation for distance is <u>speed = distance ÷ time.</u>
Rearrange the equation to make distance the subject:

<em>(multiply both sides by time)</em>

<em> </em><u>Distance = Speed × Time</u>

Convert your numbers into suitable units:

1 mile ÷ 15 = <u>0.06m/minute</u>

Finally, substitute the numbers into the equation and solve:

Distance = 0.06 × 65 = <u>4.3miles</u> (rounded to the nearest decimal place)

Divide. (3 3/4)÷(−2 1/2) Enter your answer as a mixed number, in simplified form, in the box.

neonofarm [45]

$3 \frac{3}{4} = \frac{15}{4}$

Because (4*3) + 3 = 15. Similary find the improper fraction for -2 1/2.

(15/4) / (-5/2) = -3/2

Convert -3/2 into a mixed fraction.

Therefore, -3/2 = -1 1/2.

Step-by-step explanation:

According to the <em>Slope-Intercept</em><em> </em><em>Formula</em><em>,</em><em> </em>[y = mx + b], <em>m</em><em> </em>represents the <em>Rate of Change</em> [<em>Slope</em>]. Since we ONLY have the y-intercept of [0, 7], that makes the slope 0.

A teacher is making a history test composed of the same number of multiple-choice questions as short-answer questions. She estim

STALIN [3.7K]

Answer:

The inequality is $5.5n \leq 45$

Step-by-step explanation:

Total time:

The total time to complete the test is the sum of the number of multiple-choice questions multiplied by the time it takes to solve each and the number of short-answer questions multiply by the time it takes to solve each.

In this question:

Same number(n) of both.

Multiple-choice takes 2 minutes, short-answer takes 3.5 minutes. The total time is given by:

$T = 2n + 3.5n = 5.5n$

Write an inequality to determine how many questions, n, the teacher can include if the test must take students less than 45 minutes to complete.?

This means that:

$T \leq 45$

So

$5.5n \leq 45$

The inequality is $5.5n \leq 45$
