Answer:
141 1/4
Step-by-step explanation:
You are looking for TOTAL change, thus, both values will be positive. In order to add both fractions, you need to convert the denominator for 90 1/2 into a 4. This becomes 90 2/4.
Now add both mixed fractions.
3/4 + 2/4 = 1 1/4
90 + 50 = 140
140 + 1 1/4 = 141 1/4
The answer is 14.87.
a^2+b^2=c^2
10^2+11^2=c^2
100+121=c^2
221=c^2
Square root both sides
14.87=c
Hope this helps!!
2 onea and 8 tens is a way to express it
Answer:
y = (-8/9)x + 0.77777
Step-by-step explanation:
We already know the slope, so the only thing left to find is the y-intercept.
To find the y-intercept, we can <u>plug in the slope and point to the slope-intercept form equation</u> (y = mx+b, where m=slope and b=y-int.)
y = m * x + b
(7) = (-8/9)*(-7) + b
<u>Now, just solve for b!</u>
(7) = (-8/9)*(-7) + b
7 = 56/9 + b
7 - (56/9) = b
b = 0.777777 (repeating decimal, usually signified by a little line above the 7)
so now we just <u>plug in the slope and y-intercept we found into y = mx + b.</u>
y = mx + b
y = (-8/9)x + 0.77777
i would say D) 12 is your answer
