The stucco column is 4.2 meters tall.
You have to set up a ratio.    X              2.1           
                                            ----------  =    ----------  
                                                 4               2  
Make sure to keep the heights and shadow equal to each other. then cross multiply (2.1*4) and divide (8.4/2)

What is base number​
seropon [69]

Answer: Base numbers are the number of units, or numbers, we use in our counting system, also called a number system. The most common base number is ten because the digits 0-9 are used in the number system. In other words, whenever we want to tell a number to someone we don't use any numbers besides 0-9. If it was a base-5 number system we would only use five different digits, like 0-4.

Jay sells 10 packs of apples for 80p. He wants to make £75 at the end of the year. How many packs of apples does he need to sell
ipn [44]

Answer:

937.5 packs of apples

Step-by-step explanation:

Note that:

100p = £1

80p = x

Cross Multiply

100x = 80p × £1

x = 80/100

x = £0.8

Jay sells 10 packs of apples for 80p.

Hence:

£0.8 = 10 packs of apples

£75 = x

Cross Multiply

£0.8 × x = £75 × 10 Packs

x = £75 × 10 Packs/£0.8

x = 937.5

Therefore, to make £75 at the end of the year, he has to sell 937.5 packs of apples

Given a soda can with a volume of 36 and a diameter of 4, what is the volume of a cone that fits perfectly inside the soda can?
Tomtit [17]
First we need to find the heigh of the soda can be rearanging the volume formula, V = pi * r^2* h. We can make that h =  \frac{V}{pi * r^2} We know that V is 36 and radius is half of the diameter, so radius is 2. h =  \frac{36}{pi * 2^2}
h =  \frac{36}{pi * 4}
h = 2.87

Now, we can use the height to figure out the volume of a cone. The volume of a cone is V = pi * r^2 *  \frac{h}{3}
R is 2 again and h is 2.87
V = pi * 2^2 *  \frac{2.87}{3}
pi * 4 * .96
12.56*.96 = 12.0576
So a cone with a volume of 12.0576 is the largest that will fit into the soda can
