Answer:
First we will split trapezium on two geometric figure.
One is rectangle and the second is right triangle.
When we subtract 11-4=7cm we get one cathetus of the right triangle a=7cm also we know hypotenuse which is c=16cm.
We will use Pythagorean theorem to find the second cathetus b
b=√16∧2-7∧2= √256-49= √207 ≈ 14.39cm =DC =>
AC =√(DC)∧2+(AD)∧2= √14.39∧2+11∧2= √207+121= √328= 18.1cm
AC=18.1cm
Good luck!!
Answer:
C
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 1, 0) and (x₂, y₂ ) = (0, - 3)
m = 
= - 3
note the line crosses the y- axis at (0, - 3) ⇒ c = - 3
y = - 3x - 3 ← in slope- intercept form
Add 3x to both sides
3x + y = - 3 ← in standard form → C
Answer:
4:49
Step-by-step explanation:
00:15 + 4 hours = 4:15
4:15 + 34 minutes = 4:49
Overall the answer is 4:49
8x7=56, so 56 students can sit at a table, 58-56=2 students without a table.
Your answer would be 2.
Answer:
QS=51
Step-by-step explanation:
It was given that RS = 19 and QR =32
QS=x
Q-R was measured and found to be 32
R-S was measured and found to be 19
Q-S will be the sum of Q-R and R-S which is 32+19= 51
QS=51
