Answer:
69
Step-by-step explanation:
I'm mathematics, the word 'of' transfers into becoming 'times or Multiply'
Therefore, the expression can be rewritten as:
10/100 of x = 30
10x / 100 = 30
Cross Multiply the equation to solve for x
10x = 100 * 30
10x = 3000
x = 3000 / 10
x = 300
(Since we gotten the value of x as 300) let's find 23% of it.
Therefore,
23% of x, ( when x is 300)
= 23/100 * 300
= 23 * 3
= 69
(Well, although that's the workable solution, the option doesn't seen to tally)
Maybe you check the source, but am certain about the Solution.
Let's keep learning, maths is fun !
Answer:
Quadrilateral ABCD is not a square. The product of slopes of its diagonals is not -1.
Step-by-step explanation:
Point A is (-4,6)
Point B is (-12,-12)
Point C is (6,-18)
Point D is (13,-1)
Given that the diagonals of a square are perpendicular to each other;
We know that the product of slopes of two perpendicular lines is -1.
So, slope(m) of AC × slope(m) of BD should be equal to -1.
Slope of AC = (Change in y-axis) ÷ (Change in x-axis) = (-18 - 6) ÷ (6 - -4) = -24/10 = -2.4
Slope of BD = (Change in y-axis) ÷ (Change in x-axis) = (-1 - -12) ÷ (13 - -12) = 11/25 = 0.44
The product of slope of AC and slope of BD = -2.4 × 0.44 = -1.056
Since the product of slope of AC and slope of BD is not -1 hence AC is not perpendicular to BD thus quadrilateral ABCD is not a square.

Answer:
12 divided by 2 + 4 - 2 x 3 is 4
Step-by-step explanation:
I did 12 divided by 2 first which was 6 then added 4 subtracted it by 2 then multiplied it by 3 and got 4.
