Answer:
The answer, also the only answer, is C.
Step-by-step explanation:
A: 20 is 1/2 of 40, so you would arrive at Seneca Falls in half an hour.
B: Same as a, 2 is 1/2 of 4, so you would also arrive to school in half an hour.
C: 60 is double 30, so it would take two hours to get from Albany to New York City.
Answer:
Step-by-step explanation:
sum of angles of a triangle= 180°
x+2x+2x+10=180
5x+10=180
5x=170
x=170/5
x=34
.:
x=34°
2x=34×2=68°
2x+10=2×34+10=68+10=78°
Answer:
4(x-6)(x-1) = 0
Standard form: 4x^2-28x+24=0
Step-by-step explanation:
First, let's write an equation where the roots are 6 and 1.
To do that, we can use the intercept form <em>a(x-p)(x-q) = 0</em>, where <em>a</em> is the leading coefficient, and <em>p </em>and <em>q</em> are the roots.
We can therefore plug what we know into this equation:
4(x-6)(x-1) = 0
Answer:
sale prices = $252
Step-by-step explanation: 280 - (280 x 10%) = 280 - 28 = $252
We know the area of the middle rectangle is 48 (length * width). removing that rectangle leaves us with two semicircles. you can combine those semicircles to be the equivalent of one circle. the area for a circle is r^2 * pi. we know the diameter is 4 because that is where we cut the semicircles. radius is half the diameter, so r is 2. 2^2 is 4, 4* pi is 12.56. add 12.56 (area of semicircles) with 48 (area of rectangle) and we get 60.56
