The length of a leg of an isosceles right triangle can be found using the concept of Pythagoras' theorem by the formula sqrt (hypotenuse ^ 2 / 2) = x.
Since, two sides of an isosceles triangle are equal, let us consider the two equal sides as 'x' and let the hypotenuse of the triangle be 'h'.
Being a right triangle, by Pythagoras' theorem,
h ^ 2 = x ^ 2 + x ^ 2
h ^ 2 = 2x ^ 2
Hence, we can find the length of a leg of an isosceles triangle by:
sqrt (h ^ 2 / 2) = x

Lacey graphed a system of linear equations. What is the solution to the system of
equations?
45678910
(-1,3)
(0,2)
(-4,2)
Answer:
(-1, 3)
Step-by-step explanation:
In order for a point to be a solution to a system of equations, the lines have to intersect at that point in the graph. We can see that the two lines at the graph intersect at (-1,3), so that must be the solution.

Cole bought 10 gallons of gas at the gas station with the lowest price. He paid with two $20 bills. Write and solve an equation to find his change.
Answer:
$4.3
Step-by-step explanation:
Cole bought 10 gallons of gas at the gas station with the lowest price.(the lowest price is $3.57 each gallon.) He paid with two $20 bills. Write and solve an equation to find his change.
two $20 bills = 2 * $20
= $40
Gallons of gas = 10
Lowest price of each gallon = $3.57
Cost of 10 gallons of gas = 10 * $3.57
= $35.7
Let his change = x
His change = Amount paid with - cost of gas
x = $40 - $35.7
x = $4.3
His change = $4.3

Delta math question —-
Answer:
21
Step-by-step explanation:
I think its 21, because the BD line divides the big triangle into 2 ones and they are equilateral triangle, sorry if I'm wrong
Answer:
BD = 21
Step-by-step explanation:
The sector divided AC into two equal pieces and since this is a right triangle the height of the triangle BD is equal to half of the base
(21+21) / 2 = x
42 / 2 = x
21 = x
Esha is seeking to invest for college. She selects an account with a compound interest rate of 2% per year. If she initially deposits $7,000, then how much will her investment be worth at the end of 5 years?
Answer:
$7700
Step-by-step explanation:
Given data
Rate= 2%
Principal= $7000
Time= 5 years
The simple interest expression is
A=P(1+rt)
substitute
A=7000(1+0.02*5)
A=7000(1+0.1)
A=7000*1.1
A=7700
Hence the amount is $7700

Anyone please me on this!!
Answer:
27 degrees
Step-by-step explanation:
So looking at this rhombus, we can make out 4 seperate traingles.
How many degrees are in a traingle? 180.
Looking at the traingle with z angle in it, we can see that it is a right traingle.
Now, lets subtract that 90 degrees from the 180.
This leaves us with the 63 degrees and x that make up the 90 degrees that are left.
Now all we have to do is subtract the 63 degrees from the 90 total degrees that we have left, and we will find out what z is equal to.
90 minus 63 is 27, so the angle of z is:
27 degrees
I hope this helps!
Note that I assumed these are right traingles, however I dont see how you can solve this without these being right trianlges, since you cannot use sin, cos, or tan to find this value without another angle or side length.

Graph f(x) = 6x^2-11+3 and
find the zeroes
Answer:
x = ±1.155
Step-by-step explanation:
We need to graph the given function [tex]f(x) = 6x^2-11+3[/tex] and find its zeroes.
The attached figure shows the graph of the given function.
To find zeroes,
Put f(x) = 0
So,
[tex]6x^2-11+3=0\\\\x=\pm 1.155[/tex]
Hence, this is the required solution.

Fransisco and kazuko guess the number of marbles in a jar. Fransisco guesses 50 marbles and kazuko guesses 60. The actual number of marbles is 55. Kazuko says there is less error in her guess because 50/50=10% and 5/60= 8.3%. Explain why kazuko is incorrect
Answer:
The difference in both the guessed values is 5 unit
Step-by-step explanation:
The less error computation is done by dividing the difference between the guessed value and the actual value.
Here in this case
Error in case of Fransisco = 55-50 = 5
Error in case of Kazuko = 60 -55 = 5
Hence, both have guessed incorrect value and their incorrect values is either 5 units less or 5 units higher than the actual value.

Answer:
9 π^2
Step-by-step explanation:
Let's just fined the area of the rectangle: Area= 2lw = A=60
Now, we know the diameter of the Spehre which is 10 -2 -2 = 6, the radius is half of that = 3
A=πr2 = A≈28.27
add A≈28.27 + 60 = 88.27 = 9 π^2≈88.82643
