2320 - 195 = 2125

2125 divided by 425 = 5

Your answer is B, 5

195 + 425p < = 2320
425p < = 2320 - 195
425p < = 2125
p < = 2125 / 425
p < = 5............the maximum number of palettes is 5

If a large cylinder has a volume of 28260 cubic cm, how many cylinders can be filled out of the large cylinder if the small cyli
inysia [295]
Hi,

To find the number of small cylinders that fit inside the big cylinder. You need to divide volume of small cylinder with the volume of big cylinder. We do this by using formula to calculate volume of cylinder:


v = \pi \times  {r}^{2}  \times h


To find radius just divide diameter with 2.

v = \pi \times   {2}^{2}  \times 6 \\ v = \pi \times 4 \times 6 \\ v = \pi \times 24 \\ v = 3.14 \times 24 \\ v = 75.4 {cm}^{3}


Now just division:

28260 \div 75.4 = 374.8

Answer: You could fit 374.8 smaller cylinders inside a big cylinder.

Hope this helps.

A square with an area A2 of is enlarged to a square with an area of 25A2. How was the side of the smaller square changed?
makvit [3.9K]
Given:
a square with an area of a² is enlarged to a square with an area of 25a².

The side length of the smaller square was changed when The side length was multiplied by 5.

Area = (1a)² = a²
Area = 1a * 5 = 5a ⇒ (5a)² = 25a²

A sample of 2,000 licensed drivers revealed the following number of speeding violations. Number of Violations Number of Drivers
Arturiano [62]

Answer:

The probability that a particular driver had exactly two speeding violations is 0.009.

Step-by-step explanation:

We are given that a sample of 2,000 licensed drivers revealed the following number of speeding violations;

           <u>Number of Violations</u>               <u>Number of Drivers</u>

                         0                                              1,910

                          1                                                46

                         2                                                 18

                         3                                                 12

                         4                                                  9

                         5 or more                             <u>       5      </u>

                        <u>Total</u>                                      <u>    2000  </u>

<u />

Now, the data means that 1,910 drivers had 0 speeding violations and so on.

Now, we have to find the probability that a particular driver had exactly two speeding violations, that means;

Number of drivers having exactly two speeding violations = 18

 Total numbers of drivers = 2000

So, the required probability  =  \frac{\text{No. of drivers having two speeding violations}}{\text{Total no. of drivers}}

                                               =  \frac{18}{2000}  =  <u>0.009</u>
