We know the rule of change: a b/c= (ac+b):c
So we have 2 7/8= (2x8+7):8= 23/8
and the second: 2 1/4 = (2x4+1):4= 9/4
We do the division: 23/8: 9/4= 23/8 x 4/9= (23x4):(8x9)= 23/18= 1 5/18
According to above figure, the angles (8x - 20)° and (5x + 37)° are pairs of vertical opposite angles, so
Answer:
The area is 35
The perimeter is 24
Step-by-step explanation:
You can count the individual units of the length and the width of the rectangle.
The width is 5, the length is 7
The area is 5*7=35
The perimeter is 5+5+7+7=24
That is not a trapezoid, it is a general quadrilateral. All 2-dimensional, 4-sided figures have an internal angle sum of 360 (triangles are 180). So if you assume angles P and Q are right, they are each equal to 90 degrees, for a total of 180.
Subtract: 360 - 180 = 180. We know that S + R must equal 180. If you subtract 180 - 65, you get 115, which is obtuse (greater than 90 degrees). This matches the drawing as the unknown angle is clearly greater than 90. So the answer is 115 degrees.
Answer:
13 white cars
Step-by-step explanation:
Let us represent:
Number of
Red cars = x
Blue cars = y
White cars = z
Sharon has 23 toy car that are colored red, blue, and white.
x + y + z = 23
x = 4
2 fewer blue cars than red
y - 2 = x
y - 2 = 4
y = 4 + 2
y = 6
Hence,
x + y + z = 23
4 +
Number of white cars is calculated as:
23 - (6 + 4)
23 - 10
= 13 white cars
