Answer:
[tex] {h =}^{2} = {p}^{2} \: + {b}^{2} [/tex]
[tex] {h}^{2} = {16}^{2} + {12}^{2} [/tex]
[tex] {h}^{2} = 256 + 144[/tex]
[tex]h = \sqrt{400} [/tex]
[tex]h = 20[/tex]
therefore the length of the ladder is 20ft
Find the area of the shaded region.
Answer:
60+4.5pi
Step-by-step explanation:
6×10 obv + area of circle pi(r^2) and half that for a semi cirxle
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

The solution of system of equations y=x-1 , 2x+y=8 are x=3 and y=2 which we get by substitution method.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The given system of equations are
y=x-1 ...(1)
2x+y=8...(2)
By using substitution method we solve the value of x and y.
Substitute y value in equation (2)
2x+x-1=8
Combine the like terms
3x-1=8
Add 1 on both sides
3x=9
Divide both sides by 3
x=3
Now plug in x value in y equation.
y=3-1
y=2
Hence, the solution of system of equations y=x-1 , 2x+y=8 are x=3 and y=2 which we get by substitution method.

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
simplify the expression

Lacey graphed a system of linear equations. What is the solution to the system of
equations?

(-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.

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

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:
7.9
Step-by-step explanation:
the first thing to do is find the second projection.
16-7 = 9
than we can use a proportion to find BD
7 : BD = BD : 9
BD = √9 x 7 = √63 = 7.9
we have to use the square root because in the proportion BD Is repeated two times. If we don’t use it, we find BD^2

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.
