Answer:

He needs to score 28 points.

Step-by-step explanation:

1^{st}\,\,score: 30\,\,points;\\\\2^{nd}\,\,score: 18\,\,points;\\\\3^{rd}\,\,score: 28\,\,points;\\\\4^{th}\,\,score: \,\,?

Let's calculate Dante's 4th score, given that the average is 26 points:

\frac{S1 + S2 + S3 + S4}{4} = 26\\\\\frac{30 + 18 + 28 + S4}{4} = 26\\\\76 + S4 = 104\\\\S4 = 28\,\,points.

On a treasure map, a X is placed at point (9, -7). if the pirates are currently on point (9,3), how many units away are they?​
Alex_Xolod [135]

They are 10 units away from the treasure

Step-by-step explanation:

Notice that the points (9, -7) and (9, 3) are both located at the same x-value (9) while their y-values are in one case 3 units above the x-axis, and in the other 7 units BELOW the x-axis. Therefore thy differ by 3 - (-7) units , which totals 10 units.

aleksklad [387]

Answer:

<u>5.56 hours</u>

Step-by-step explanation:

Margo read 42 pages in 2.5 hours.

Pete read six fewer pages in the same amount of time.

So, The number of pages that Pete reads = 42 - 6 = 36 pages

So, Pete read 36 pages in 2.5 hours.

let the time needed to read 80 pages x

∴ 36 pages ⇒ 2.5 hours

   80 pages ⇒  x   hours

∴\frac{36}{80} = \frac{2.5}{x}

Using cross multiplication:

∴x = \frac{80*2.5}{36} = \frac{200}{36}=5\frac{5}{9}=5.56

So, The time taken to read 80 pages

= <u>5.56 hours = 5 hours and 33.33 minutes</u>
