Answer:

Step-by-step explanation:

Given that ABCD is a parallelogram.

E is the point where the diagonals AC and BD meet.

Consider triangles ABE and CDE

Statement Reason

--------------------------------------------------------------------

1) AB =CD Opposite sides of a parallelogram

2) Angle ABE =

Angle EDC Alternate angles of two parallel lines

3) BE = DE Diagonals bisect each other in a parallelogram

Hence by SAS axiom the two triangles are congruent.

anastassius [24]

Here are the equations
x+y=48
x/y=5/8

but here's how I would solve it

5+7=12
48=12units
divide by 12 both sides
4=1unit

males=5 unit
4=1unit
times 5
20=5unit=males

females=7unit
4=1unit
times 7
28=7unit=females

makvit [3.9K]

Well, if you take x to be 25 seconds, there are 2.4x in 1min. So, that multiplied by 60, would be 144x. Therefore, 1/4 multiplied by 144x should be the answer.

A pound of oranges costs $2 less than a pound of pears. Together, ten pounds of oranges and eight pounds of pears cost $61. How

Thepotemich [5.8K]

Let us say that:

o = cost of oranges per pound

p = cost of pears per pound

so that:

o = p – 2

Therefore:

10o + 8p = 61

10 (p – 2) + 8p = 61

10p – 20 + 8p = 61

18p = 81

p = 4.5

p = $4.5 per pound

So 3 pounds of pears would cost:

total cost = 3 * 4.5

total cost = $13.5

The grades on a history midterm at Gardner Bullis are roughly symmetric with μ = 69 μ=69mu, equals, 69 and σ = 3.5 σ=3.5sigma, e

katrin2010 [14]

Answer:

-1.14

Step-by-step explanation:

The given information in statement is

mean=μ=69

standard deviation=σ=3.5

Let X be the Ishaan's exam score

X=65

The Z score can be computed as

$z=\frac{x-mean}{standard deviation}$

$z=\frac{65-69}{3.5}$

z=-1.1429

z=-1.14 (rounded to two decimal places).

Thus, the computed z-score for Ishaan's exam grade is -1.14.
