Answer:
B
Step-by-step explanation:
the order of a matrix are given as
m × n ( m is the number of rows and n the number of columns
matrix A is of order 2 × 3
matrix B is of order 3 × 2
for the matrices to be conformable for multiplication then
the number of columns in A is equal to the number of rows in B
This is the case here , then the order of the resulting product is
AB : 2 × 3 × 3 × 2 the outer values , that is 2 × 2

A carpenter lays 18 square feet of tile in 2/3 of an hour. How many square feet of tile does the carpenter lay per hour?
Answers
Answer:
x=24
Step-by-step explanation:
there are different ways to solve the problem
set up a proportion:
16/(2/3)=x/1
cross multiply
(2/3)x=16
(3/2)(2/3)x=(3/2)(16)
x=24 square feet per hour
a carpenter lays 16 square feet in 40 minutes (2/3 of an hour)
this means he lays 4 square feet every 10 minutes
8 square feet in 20 minutes
12 square feet in 30 minutes
24 square feet in 60 minutes

A child is flying a kite. If the string is pulled tight to its full length of 40 feet and is held at an angle of 71 degrees above the ground, how high is the kite? Round your answer to the nearest whole foot.
Answers
Answer:
38feet high
Step-by-step explanation:
Given the following
Length of the string = 40feet (hypotenuse)
Angle of elevation = 71 degrees
Required
Height of the kite (opposite)
Using the SOH CAH TOA identity
Sin theta = opp/hyp
Sin 71 = H/40
H = 40sin 71
H = 40(0.9455)
H = 37.82
Hence the kite is 38feet high (to the nearest whole number)

Volume of cuboid is length* breadth" height
Volume of cuboid is length* breadth" height=10*8*6= 480cm³
volume of traingular prism= this I don't know
okay wait...imagine there is other half of the traingle such that it becomes cuboid...now find area of cuboid = 5*5*4= 100
now divide by 2 to get half volume ( one triangular prism)
which is 100/2= 50
Volume of traingular prism= 50cm³
Total volume of figure= 480+50= 530cm³
PLS HELP NO LINKS. Assume that RQ and RS tangent to circle T. solve for x.
Answers
Answer:
x = 6
Step-by-step explanation:
Here, we want to solve for the value of x
mathematically, tangents drawn from the same point to touch two points on a circle, are the same distance from the external point
thus;
QR = RS
Thus;
3x + 8 = 26
3x = 26-8
3x = 18
x = 18/3
x = 6
