Answer:
108pi
Step-by-step explanation:
We do not need to know the height and radius, as the formula for the volume of a cone is just a third of the volume of a cylinder. So we have 36pi * 3 or 108pi.

At the zoo, Peter saw 9 animals. Some are kangaroos and some are
elephants. There are 30 legs in all. How many of each animal are there?
Answer:
6 elephants and 3 kangaroos in the zoo.
Step-by-step explanation:
Number of animals = 9
Number of legs seen = 30
But an elephant has 4 legs, while a kangaroo has 2 legs.
Let the number of elephant be represented by E, and the number of kangaroo by K.
So that,
E + K = 9 .................. 1
4E + 2K = 30 ............. 2
Multiply equation 1 by 2 to have
2E + 2K = 18 ............ 3
Subtract equation 3 from 1
2E = 12
E = 6
Substitute the value of E in equation 1
E + K = 9
6 + K = 9
k = 3
Thus, there were 6 elephants and 3 kangaroos in the zoo.

Estimate the total weight of two million pounds worth of two pence coins in kilograms. A two pence coin weighs 7.1g.
Answer: 710,000 kg
Step-by-step explanation:
There are 100 pence in one pound.
The number of two pence coins in 1 pound is therefore:
= 100 / 2
= 50 coins
In 2 million pounds therefore, there will be:
= 50 * 2,000,000
= 100,000,000 two pence coins
If one coin weighs 7.1g, weight is:
= 100,000,000 * 7.1
= 710,000,000 g
A kg is 1,000 grams so the weight in kg is:
= 710,000,000/1,000
= 710,000 kg

Find a correct to 2 decimal places.
NOTE: The triangle is NOT drawn to scale.
102
27°
41°
х
Answer:
317.52
Step-by-step explanation:
Label the point where the altitude meets the base P and the end points of the base A and B where m∠A = 27 and m∠B = 41
tan 27 = 102/AP and tan 41 = 102/PB
APtan 27 = 102 PBtan 41 = 102
AP = 102/tan 27 PB = 102/tan 41
AP = 200.186 PB = 117.338
x = AP + PB = 200.186 + 117.338 = 317.52

shopkeeper sells tins of the same dog food in packs of four or packs of six.
Packs of four tins cost £1. Packs of six tins cost £1.20
Which is the best value for money?
You must show your working.
Answer:
Pack of 6
Step-by-step explanation:
Pack of 4 = £1
Packs of 6 = £1.20
Price per unit of each pack:
Pack of 4 ;
Unit price : cost / units
Unit price = £1 / 4 = £0.25
Pack of 6 ;
Unit price : cost / units
Unit price = £1.20 / 6 = £0.20
Pack of 6 is the best value for money as it has a lower unit price

4x + 3y = 6
2x - y = -2
Answer:
Add the equations in order to solve for the first variable. Plug this value into the other equations in order to solve for the remaining variables.
Point Form:
(0,2)
Equation Form:x=0, y=2
Answer:
(0,2)
Step-by-step explanation:
Multiply each equation by the value that makes the coefficients of y opposite.
3*2x-y=3*-2
Simplify
6x-3y=-6
Add the two equations
10x = 0
Divide both by 10 and simplify
x=0
Substitute x into the equations.
4*0+3y=6
