here's your answer hope it helps.
Step-by-step explanation:
1. decimal:
39/50=0.78
2. percentage:
39/50=78%
9/50 to a decimal is 0.78 and a percent is 78%.
To convert fraction into decimal, divide the top of the fraction by the bottom number (39/50) here 39 is the top of the fraction and 50 is bottom of the fraction.
39/50 = 0.78
To convert fraction into percent, divide the top of the fraction by the bottom number then multiple the result by 100 here 39 is the top of the fraction and 50 is bottom of the fraction then multiple the result(0.78) by 100.
39/50 = 0.78 * 100 = 78.
Therefore, 39/50 to a decimal is 0.78 and a percent is 78%.

Answer:
-11 yd/s
Step-by-step explanation:
We basically have to the find slope between the given points
Let h(t)₁ = 0
h(t)₂ = 33
t₁ = 6
t₂ = 3
We have to find the change in distance (h(t)₁ - h(t)₂) then divide it by the change in x (t₁ - t₂)
6 - 3 = 3
This means the change of x is 3
0 - 33 = -33
This means the change in distance is -33
Now divide -33 by 3
-33 ÷ 3 = -11

These 3 please!!! Properties of Kites and Trapzoids exercises 1-3
Answer:
area = 1/2(AC)(BD)yes; BE can be found using the Pythagorean theoremyesStep-by-step explanation:
1.Triangles ADB and CDB are congruent, so each is half the total area. The area of ADB is ...
A = 1/2bh
A = 1/2(DB)(1/2AC) = 1/4(DB)(AC)
The area of the kite is twice this value:
A = 1/2(DB)(AC)
__
2.In order to use the formula derived in part 1, we need to know the length of BE. That can be found using the Pythagorean theorem:
BE² +AE² = AB²
We know that AE = 1/2AC, so the desired dimension is ...
BE = √(AB² -(1/4)AC²)
Then the area of the kite is ...
area = 1/2(DB)(AC)
area = (1/2)(AC)(ED +√(AB² -(1/4)AC²)
__
3.Given three sides of a triangle, the area of it can be found using Heron's formula. If you have not yet seen that in your geometry class, you can always use the Pythagorean theorem and some algebra.
As before, we need to know the lengths of the diagonals. One is given. The other can be found considering the Pythagorean relations:
AD² = AE² +DE²
AB² = AE² +BE²
BE +DE = BD . . . . the sum of the horizontal diagonal lengths
Subtracting the second equation from the first gives ...
AD² -AB² = DE² -BE²
Using the third to write an expression for DE, we get an equation for BE:
AD² -AB² = (BD -BE)² -BE²
AD² -AB² = BD² -2BD·BE +BE² -BE²
(AB² +BD² -AD²)/(2BD) = BE
Substituting this into the original second equation, we can find AE, hence the area of the kite.
AE² = AB² -((AB² +BD² -AD²)/(2BD))²
Which means the kite area is ...
area = BD·AE = BD√(AB² -((AB² +BD² -AD²)/(2BD))²)
area = (1/2)√(4·AB²·BD² -(AB² +BD² -AD²)²
This area formula demonstrates it is possible to find the area of the kite given the three lengths AB, BD, DA.

We have no doubt that the area formula of Part 3 can be rearranged to match Heron's formula. Here, we're interested in demonstrating area can be found.

What are congruent triangles?
23) We are given a rectangle RSTU with diagonal US.
Now, we are told that;
UR is parallel to ST
∠R and ∠T are right angles
We can say that for ΔRSU and ΔTUS, that US is equal to itself in both cases by the reflexive property of congruence.
Now, since ∠R and ∠T are right angles, it means that UR is equal to ST.
Thus for the two triangles;
UR = ST
US = US
∠R = ∠T
There are two corresponding equal sides and one corresponding equal angle and as such, ΔRSU and ΔTUS are congruent by SAS congruency postulate.
18) We are given that;

Answer: 38
Step-by-step explanation:
We know it's a parallelogram b/c there are 2 pairs of opposite parallel sides.
So this means that AB = DC = 9 and BC = AD = 10 since opposite sides of a parallelogram are congruent.
Meaning perimeter = 9 + 9 + 10 + 10 = 38
1) what’s the greatest common factor
35, 28
2) what’s the greatest common factor
36, 27
Answer:
GCF 35, 28 is 7
GCF 36, 27 is 9
Step-by-step explanation:
Greatest means biggest.
Common means same.
Factor means a number that goes evenly into the number. (3 goes into 27, so 3 is a factor of 27. 5 doesn't go evenly into 27, so 5 is not a factor of 27)
The biggest number that goes into both 35 and 28 is 7.
1, 5, 7, 35 are factors of 35.
1, 2, 4, 7, 14, 28 are factors of 28.
The biggest factor that's the same is the 7.
factors of 36:
1, 2, 3, 4, 6, 9, 12, 18, 36
Factors of 27:
1, 3, 9, 27
The biggest same factor is 9

Is triangle EJH congruent to triangle EIH?
Answer: yes
Step-by-step explanation:
Side JH and side HI are congruent and angle J and angle I are congruent so the two triangles are also congruent
The given two triangles EJH and EIH are congruent by the RHS congruency rule of two triangles.
Congruence of triangles:
If two or more triangles having same size and shape, then they are congruent to each other.
Every angle and sides are must be equal to each other and hence area is also equal.
How to show congruence in right angled triangles?
Here we have given that two triangles EJH and EIH, both are right angled triangles.
In any two right angled triangles having same hypotenuse and base side then they are congruent to each other by the RHS congruency
Here we have given side HJ ≅ side HI
∠EJH = ∠EIH = 90°
The common side EH is hypotenuse for both that is side EH = side EH
Therefore by RHS criteria these two triangles are congruent.
