The pyramid is shown in the diagram below.
The pyramid is built from four congruent triangles and one square as the base
We have the side of the square, so the area is = 10×10 = 100
We need the height of the triangle to work out its area. We can find out by using the height of the pyramid and half of the length of the side of the square.
Using the Pythagoras rule
Height of triangle =
Area of one triangle = 1/2×10×12=60
Surface area of the pyramid = 100 + (4×60) = 340 square inches
Answer:
Step-by-step explanation:
It must end in (divisible by 2 rule) and the digits must sum to a multiple of 9(divisible by 9 rule).
The digit sum is .
We want to make as low as possible because it's a higher digit than .
If is as low as possible, we have that the sum is . Uh-oh. has to be even! So doesn't work.
If , we have that the sum is . Yay!
So, the answer is
Answer:
5 i believe correct me if im wrong
Step-by-step explanation:
To work this problem out you would do it as if it were just a simple equation
7x-19<16 (you would first have to add 19 to both sides)
7x<35 (then you would divide by 7 to get the variable by itself)
x<5 ( you answer would then be 5)
