140/7=20
220/20=11
the answer is 11
Answer:
(0, - 2)
Step-by-step explanation:
The y-intercept is the value of y when x = 0. Substitute 0 for x in the equation and solve for y.
When x = 0, y = - 2.
Answer:
base(b)=10 and height(h)=6
Step-by-step explanation:
From the question,
base(b)=x feet
height(h)=(x-4) feet
Area(A)=30 square feet
Now,
We know,
Area of triangle(A)=1/2*b*h
or, 30=1/2*x*(x - 4)
or, 30=1/2*x^2 -4x
or, 30*2=x^2 -4x
or, 60=x^2 -4x
or, 0 = x^2 -4x -60
or, 0 = x^2 +6x - 10x -60
or, 0 = x(x + 6) -10(x + 6)
or, 0 = (x+6) (x-10)
Either,
x+6=0. or, x-10=0
or,x= -6. or, x= 10
Since, the base of the triangle can not be negative number then, x≠ -6feet but x=10feet
Lastly,
Height(h)=X - 4
=10 - 4
=6 feet
Answer:
2/5
Step-by-step explanation:
To figure out which is larger, you must first find the common denominator.
Multiply the denominators to find a common denominator:
8 x 5 = 40
Then, cross-multiply to find the new numerators:
2 x 8 = 16 3 x 5 = 15
You now have:
2/5 = 16/40 and 3/8 = 15/40
So, 2/5 is larger!
<span>I found the following about exponential notation at this site:
http://www.vendian.org/envelope/dir0/exponential_notation.html
"Exponential notation lets you move the decimal point in a number. It
simplifies numbers by getting rid of zeros, and making math easier. Getting
rid of zeros helps with big 100,000,000 and small 0.000,000,001 numbers.
