Yes, this is the right answer
Three main methods come to mind: Substitution method, Elimination method, Matrix row-reduction.The first two methods are taught in early grades in most high schools. Matrix row-reduction is taught in senior years in high school, or more likely, in the early years of a university math or science program.
Answer:
A
Step-by-step explanation:
angle A is 90 and c and b have to be equal
Answer:
28.4in³
Step-by-step explanation:
Volume of the square based pyramid = L²H/3 where;
L is the length of a side of the square base
H is the height of the prism
Given
Perimeter of the base = 13.4 in
Height of the pyramid = 7.6in
First we need to get the length of the square base
Perimeter of a square = 4L
13.4 = 4L
L = 13.4/4
L = 3.35 in
Next is to find the required volume of the pyramid
V = L²H/3
V = 3.35²(7.6)/3
V = 85.291/3
V = 28.4 in³
Hence the volume of the pyramid to nearest tenth is 28.4in³
Answer:
1.0125
Step-by-step explanation:
Since b/a is 0.75 and a is given as 0.35
Then let's start by solving for b
Ok...how
b/a=0.75
a=0.35
Then make b the subject of formula
b=0.75×a
Then substitute the value of a
b=0.75×0.35
b=0.2625
Let's continue
b and a means b + a
0.75+0.2625
1.0125
Therefore the final answer is 1.0125
