Answer:
Step-by-step explanation:
We are given a ΔKLM, in which KL=LM=13 in and KM=10 in which means two sides of the given triangle are same and thus is an isosceles triangle.
Its median drawn from L to the KM will be altitude. Therefore, ΔKLN and ΔLMN are right triangles.
In ΔKLN, using the pythagoras property, we have
Now, Area of triangle= 1/2×base×height
=1/2×10×12
=60 squared inches.
Answer:
Step-by-step explanation:
You would time the denominator by 3 so 11*3 would be 33 then times the numerator by the same so 6*3 soot would be 18/33
Answer:
8) v = 312
9) s = -12/13
Step-by-step explanation:
8) Multiply left and right by -14, then you get
v-18 = -21*-14
v-18 = 294
Add 18 left and right:
v = 294 + 18
v = 312
9) Add 26 left and right
-13s = -14 + 26
-13s = 12
Divide left and right by -13
s = -12/13
The register contains 8 number of $20 bills and 13 number of $100 bills.
<h3>What is termed as the linear equation in two variables?</h3>
- A linear equation in two variables is one that is written in the form ax + by + c=0, where a, b, and c are real numbers as well as the coefficients of x and y, i.e. a and b, are not equal to zero.
Let 'x' be the of $20 bills.
Let 'y' be of $100 bills.
Total bill = 21
x+y = 21
y = -x+21 ......eq1
Now,
Total price = $1460.
20x + 100y = 1460
Put value of y from eq 1.
20x + 100(-x+21) = 1460
20x-100x+2100=1460
-80x=-640
x=8 (Number of $20 bill)
And,
-8+21=13
y=13 (Number of $100 bills)
Thus, the register contains 8 number of $20 bills and 13 number of $100 bills.
