Question 2

irakobra [83]

Answer :

2 hours 36 minutes

Step-by-step explanation :

speed = distance / time

Distance = 150 km

time = 1 hour 30 minutes

= 1,5 hours

$speed = \frac{150 \: km}{1.5 \: hours}$

$speed = 100 \: km/hour$

<h3>Answer :</h3>

How long will it take the car to cover a distance of 260 km at the same average speed ?

Time = Distance/Speed

= 260 km / 100 km/hour

= 2,6 hours

____________________

to convert hours to hours and minutes we can multiply by 60.

2, 6 hours

2 hours and 0,6 hours

0,6 = 3/5

3/5 × 60

60 ÷ 5 × 3

36 minutes

2,6 hours = 2 hours 36 minutes

Find the scale factor of the two cylinders:

Figure A has an r of 4 and figure B has an r of 2:

2 / 4 = 0.50, so Figure B is half the size of Figure A.

Since you want the volume, which is measured in cubic units, you need to cube the scale factor:

0.5^3 = 0.125

Multiply the volume of Figure A by the scale factor:

352 x 0.125 = 44 cubic feet.

Jamal bought a diamond ring at a 20% discount. He paid $2640 for the ring. Naomi bought a similar ring but was given a discount

Fudgin [204]

Answer: 72%

Step-by-step explanation:

Set Jamal's original ring price = x

$x - x(0.2) = 2640\\x(1-0.2)=2640\\x(0.8)=2640\\x=\frac{2640}{0.8}=3300$

Jamal's original ring price = $3300

Set Naomi's discount = y

$3300-3300(y)=924\\=3300(1-y)=924\\1-y=\frac{924}{3300} \\-y=\frac{924}{3300} -1\\y=1-\frac{924}{3300}=1-0.28=0.72$

Naomi's discount is 0.72 = 72%
