1.what is definition and
properties of kite.
2.write definition and properties of parallelogram along with diagram
Answer:
1..ans- kite is a quadrilateral in which two disjoint pairs of consecutive sides are congruent (“disjoint pairs” means that one side can't be used in both pairs). ... The opposite angles at the endpoints of the cross diagonal are congruent (angle J and angle L).
The sum of the ages of two brothers is 37.7 years. The older brother is
7.9 years older than the younger brother. The line graphed on the
coordinate grid represents the first of two equations in a system of linear
equations that can be used to find their ages.
If the second equation is x+y=37.7 , which value is closest to x, the age of the older brother in years?
a. 8
b. 15
c. 23
d. 30
Answer: 15
Step-by-step explanation: because 7.5 is in the middle of 5 and 10 and it goes straight down to 15
A rectangles base is 2in. Shorter than twice its height. The rectangles area is 40in^2. Find it's dimensions.
Answer:
5 in by 8 in
Step-by-step explanation:
Given that :
Area, A of rectangle = 40 in²
Let
height = x
Base = 2x - 2
Area of rectangle = L * B
40 = x * (2x - 2)
40 = 2x² - 2x
2x² - 2x - 40 = 0
x² - x - 20 = 0
x² - 5x + 4x - 20 =0
x(x - 5) +4(x - 5) = 0
x - 5 = 0 or
x + 4 = 0
x = 5 or x = - 4
X cannot be negative
X = 5
Height = 5
Base = 2*5 - 2 = 8

48-12=36
4x=36
divide by 4
x=9
Answer: A) x=9
48-12=36.
36/4=9
More detailed explanation:
4x+12=48
-12 -12

/4 /4
x = 9
Step-by-step explanation:
subtract 12 from both sides , then divide both sides by 4

f(x)=
Answer:
f
f(x) =-3/4x +2
Step-by-step explanation:
You have points (0,2) and (-4,5) Soo the slope is 5-2/-4-0 = 3/-4
Then f(x) = mx+b. So f(x) = -3/4x + 2 because the y intercept is (0,2).
Answer:
f(x)= -x+2
Step-by-step explanation:
Looking at the graph gives us this information:
SLOPE
you can see that for every 1 unit over, it goes one unit down.
slope = rise / run which would be -1/1 which is also just -1
INTERCEPT
the y intercept is 2
equations are typically written in y=mx+b form (where m is the slope and b is the intercept)
so we have y = -1x +2
you don't need to write the 1 because -1x is the same as -x
sof(x)= -x+2
Find the length of BC
Answer:
It would be 123
Step-by-step explanation:
If r varies directly as t andr= -20 when t = 4, find r when t= -6.
Answer:
Step-by-step explanation:
t r = k/t Where k = constant of proportionality 132 = k/4 k = 4 x 132 k = 528 Formula r = 528/t Using formula r = 528/32 r = 16.5 Hope this helps :-) ...
The value of r should be considered as the 16.5 at the time when t = 4.
Calculation of the value of r:Since we know that
t r = k/t
here k = constant of proportionality
So,
132 = k/4
k = 4 x 132
k = 528
Now
r = 528/t
r = 528/32
r = 16.5
hence, The value of r should be considered as the 16.5 at the time when t = 4.

If y varies directly as x, and y =6 when x =10, find x when y=18
Answer:
X=30
Step-by-step explanation:
y=kx
6=10k
k=0.6
y=0.6x
18=0.6x
X=18/0.6
x=30
The value of x when y = 18 is 30.
What is Direct Variation?Direct variations are defined as the functions of the form y = kx, where k is a constant.
Here when y increases, x increases and if y decreases, x also decreases.
Given that y varies directly as x.
That is the equation relating y and x can be written as,
y = kx, for some constant k.
Given that,
When x = 10, the value of y = 6.
Substitute in the equation.
6 = 10k
k = 6/10 = 3/5
Now we have to calculate the value of x when y = 18.
Substitute the found values and given values in the equation.
18 = (3/5) x
x = (18 × 5) / 3
x = 30
Hence the value of x is 30 when y = 18.

B 5 1/2
Hope it helped!!!
pls tell me how to do it
Answer:
1) 35
2) 125
Step-by-step explanation:
1)
angle adc = x
x+ 90 + 20 = 180 (triangke sum property)\
x = 180 - 110 = 70
angle bdc = 70/ 2 = 35 ( the median cuts the angle into 2)
2) cbd = x = 125
x + c + bdc = 180
x + 35 + 20 = 180
x = 180 - 55 = 125
I hope im right!!!

9514 1404 393
Answer:
9 miles
Step-by-step explanation:
Of course, 45 min = 45/60 hours = 3/4 hours.
__
The relationship between time, speed, and distance is ...
distance = speed · time
distance = (12 mi/h) · (3/4 h) = 9 mi
Her position will be 9 miles from 0 after 3/4 hour.

Jenny and Laura share £30 in the ratio of 3:2 work out how much money jenny gets
Answer:
Jenny gets €18.
Step-by-step explanation:
Jenny gets 3 of every Laura's 2. First you add together both numbers in the ratio. 3+2=5. Then you divide the constant, 30, by the sum, 5. 30/5=6. Then you multiply each number of the ratio by the quotient. 3 x 6=18.
One question, seventh grade question, please help! It’s not long!
Answer:
The Correct Answer Is 4
Step-by-step explanation:
So if you have $12 and you can buy $3 with each box of envelopes, you think, how many times can 3 go into 12
count in your head, 3 6 9 12 therefore, ITS 4
here is your equation to match this:
3 x ? = 12
You probably already know this, but i simple way to figure this out is to flip the equation to
12/3 = ?
so from here you can tell that 3 goes into 12 4 times
so the equation is
3 x 4 = 12

Number 13 Find the measures of angles 1, 2, and 3.
Answer:
1. 37
2. 26
3. 26
Step-by-step explanation:
Subtracting 63 from 180, you find the linear pair, being 117 which helps find an angle in the lower triangle. The sum of all angles is 180, and to find 2, you subtract the known angles ( 180-(37+117)) which equals 26. Knowing the shape is a parallelogram, and the opposite sides are parallel, we can say 2 and 3 are congruent through the alternate interior angles theorem. 1 is found through applying the same theorem.
