BC= 12cm
AC = 5cm
According to Pythagoras theorem ,
12^2 + 5^2 = AB^2
144+25 =169 ..
so AB^2 = 169
AB=√169 ..
Therefore, AB= 13cm ..

I thought of a number, subtracted it from 6 1/4 , multiplied the difference by 1 2/3 and then by 2 4/5 . The result was the same as the result of division of 146 by 5 3/14 . What was my number?
Answer:
The number was 1/4
Step-by-step explanation:
Let the
number be x
from the question, we have
6 1/4 - x
multiplied difference;
(6 1/4 - x) 1 2/3
The
next multiplication will give;
1 2/3 * 2 4/5
= 5/3 * 14/5 = 14/3
So we have;
(6 1/4 - x) 14/3
Result is same as:
146 divided by 5 3/14
= 146 * 14/73 = 28
Thus;
(61/4 - x) * 14/3 = 28
(25/4 - x) * 1/3 = 28/14
(25/4 - x) * 1/3 = 2
(25-4x)/4 = 6
25-4x = 6(4)
25-4x = 24
25-24 = 4x
4x = 1
x = 1/4

What is the volume of the triangular prism
Hight 10in
Base 14 in
Length 6
Answer:
[tex]V=336\ in^3[/tex]
Step-by-step explanation:
Triangular Prism
Given a triangular prism of base area A and height H, its volume is obtained with the formula:
V = AH
The area of the base is calculated as follows:
[tex]A = \frac{WL}{2}[/tex]
Where W is the width and L is the length. Both dimensions must be perpendicular.
The triangle of the base has a hypotenuse equal to 10 in and the width is 6 in, the length is calculated by:
[tex]L=\sqrt{10^2-6^2}[/tex]
[tex]L=\sqrt{100-36}=\sqrt{64}[/tex]
L = 8 in
The area is:
[tex]A = \frac{6*8}{2}[/tex]
[tex]A = 24\ in^2[/tex]
Finally, the volume is:
[tex]V = 24\ in^2*14\ in[/tex]
[tex]\boxed{V=336\ in^3}[/tex]

How do you simplify square roots.
Answer:
Simplifying a square root just means factoring out any perfect squares from the radicand, moving them to the left of the radical symbol, and leaving the other factor inside the radical symbol. If the number is a perfect square, then the radical sign will disappear once you write down its root.

How much space does Riya have left in the room. Give your answer in metres.
Answer:
1.84 (precisely)
Step-by-step explanation:
width of the cupboard = 1m
1m to cm
1 × 100= 100cm
100cm + 84cm = 184cm
1m = 100cm
184/100 = 1.84m

This sign shows when a lift is safe to use.
Total mass of people must be 480 kg or less
Fred and some other people are in the lift and their total mass
is 565 kg to the nearest 5 kg.
Fred, who has a mass of 88 kg to the nearest kg, gets out of the lift.
Is the lift now safe to use?
You must show your working and clearly state 'Yes it is safe' or 'No it is not safe'
Answer:
Yes it is safe
Step-by-step explanation:
lower bound of fred's weight (88kg) = 87.5kg
upper bound of total mass (480kg) = 567.5 kg
567.5kg - 87.5kg = 480 kg
The total mass in the lift after Fred gets out is [tex]477[/tex] kg which is less than the safe limit of [tex]480[/tex] kg. So, the lift is safe to use.
Maximum mass in the lift [tex]= 480[/tex] kg.
Total mass of Fred and other people in the lift [tex]= 565[/tex] kg.
Mass of Fred, in nearest kg, [tex]= 88[/tex] kg.
Fred gets out of the lift. So, subtract the mass of Fred from the total mass in the lift.
Total mass of people in the lift [tex]= 565-88 = 477[/tex] kg, which is less than safe limit of mass in the lift.
So, the lift is safe to use now.

A force of 450 N is exerted with a pressure of 15 N/m2.
Calculate the area to which the force has been applied.
134356377489486467347
Step-by-step explanation:
Force (F) = 450 N
Pressure (P) = 15 N/m² or 15 pa
Area (A) = ?
We know the force acting normally per unit area is pressure so,
P = F / A
15 = 450 / A
A = 450 / 15
A = 30 m²
The area to which the force has been applied is 30 m².
