Answer:

QT = RT

Step-by-step explanation:

When drawing triangle PQR the perpendicular bisector cuts the triangle in half, which results in two sides that are congruent. This makes QT and RT congruent.

natima [27]

Answer:

1.5 batches take 12.375 hour

Step-by-step explanation:

The first batch takes 10.5 hours, meaning only .5 batches are left. You then take the time that each new full batch takes (4.25) and divide it by 2 as you only need half of one batch. Meaning 0.5 of a batch takes 2.125 hours. You then take the time of the two batches (10.5, and 2.125) and add them, leaving you with 12.625. Meaning 12.375 is the most viable answer.

Neko [114]

Distance traveled in the first hour = 50 miles

Distance traveled in the second hour = 72 miles

Distance traveled in the third hour = 46 miles

Total distance = 50 + 72 + 46 = 168 miles

23 miles = 1 gallon

168 ÷ 23 = 7.30 gallons (nearest hundredth)

Answer: 7.30 gallons

A cylinder and a cone have the same base and height. The cylinder can hold about 4,712 mc015-1.jpg of sand. Jared says that the

exis [7]

The correct answer is C. So, lets go first to the equations that determine the volume of these solids. For the cylinder, that is simple; pi*r*r*h where r is the radius, h is the height and pi is the constant 3.14. For the cone, it is not easy to derive but one gets that the formula is: $\frac{ \pi*r^2*h}{3}$ .

We notice thus that $V_{cyl}=\pi*r^2*h=3V_{cone}$ . That holds irrespective of their radius or height; we only need to know that the heights and radii of the two objects are the same. Now, we have thus that:
$\frac{V_{Cyl}}{V_{Cone} } =1/3$ .

We can check if this holds for Jared's statement; 1178/4712=0.25=1/4. So, it does not hold and thus Jared's statement is incorrect.
