Answer: (4x + 5y = 4) =4/5=0,8
(2x - y = 9)= 9/2=-0,9
Step-by-step explanation:
Answer:
8 units squared.
Step-by-step explanation:
Assuming the numbers are the length and width, we can use the formula for finding the area of the rectangle.
The area should be eight units squared.
Question 1 - Answer:
Angle bisector – ray that divides an angle into two congruent adjacent angles. Triangle – the figure formed by three segments joining three noncollinear points. Each of the three points is a vertex of the triangle and the segments are the sides.
Question 2 - Answer:
Two adjacent angles whose noncommon sides are opposite rays. Two angles whose measures sum to 90 degrees. Two angles whose measures sum to 180 degrees. If two angles form a linear pair, then they are supplementary.
Question 3 - Answer:
The sides of a right triangle have different names: The longest side, opposite the right angle, is called the hypotenuse. In the diagram, the hypotenuse is labelled c. The other two sides are called the legs of the triangle.
Answer:
106
Step-by-step explanation:
Given :
Number of the set of siblings = 20
This 20 pair yields = 103.29, = 103.75, requals = 0.899, P-value = 0.000
Let x represents the IQ score of the younger child.
And y is the predicted value of Y(^).
So according to the question,
x = 105
and y = -9.5 + 1.1 x
Then,
y = -9.5 + 1.1 (105)
y = -9.5 + 115.5
y = 106
So the best predicted value of Y(^) is 106
A = (1/2)base*height
Since this is an equilateral triangle each side is 34 inches, the altitude bisects the base into two 17 inch segments
There is now a right triangle with a base of 17 inches and a hypotenuse of 34 inches, so the pythagorean theorem (a^2 + b^2 = c^2) can be used
17^2 + b^2 = 34^2
or b^2 = 34^2 - 17^2
b^2 = 867 (take the square root of both sides)
b = 17
so the height of the equilateral triangle is 17
A = (1/2)(34)(17
)
A = 500.56 square inches
