Answer:
Uma is 11 years 11 months 4 days older
Step-by-step explanation:
Given
Let
x = Uma's age
y = Her brother's
So:
x = 12years 9months 5days
y = 10 months 1 day
Required
How much older is Uma
To do this, we simply calculate the difference (d) in their ages:
This gives:
d = [12 years 9 months 5 days] - [10 months 1 day]
Collect like terms
d = [12 years 9 months - 10 months] + [5 days - 1 day]
d = [11 years 11 months] + 4 days
d = 11 years 11 months 4 days
Answer:
10.44 feet
Step-by-step explanation:
You need to use the Pythagorean Theorem twice.
First we have to find the diagonal for the base.
6²+8²=x²
36+64=x²
100=x²
√100=x
x=10
Now we can find d.
10²+3²=x²
100+9=x²
109=x²
√109=x
x=10.44 feet

Answer:
40 degrees
Step-by-step explanation:
The 100 degree angle is supplementary to angle CED. This means CED will end up being 80 degrees. Since the angles in all triangles equate to 180 degrees 80 + 60 + angle D must equal 180 degrees. Therefore, angle D has to be 40 degrees.
Answer:
Step-by-step explanation:
I don't see Wen's work, but I'll show you mine!
We can create a set of coordinates for each of these sets of data, where x is the time in hours, and y is the number of degrees in Fahrenheit.
At time 0, the temp is 0: (0, 0)
5.75 hours late, the temp is -15.5: (5.75, -15.5)
We can find the change in temp per hour by using the slope formula, since slope is, after all, the rate at which something is changing.
That is rounded to the tenths place from -2.695652174 so you can round it however you need. What the interpretation of this number is is that temp is falling at a rate of 2.7 degrees F per hour.
