Answer: 7
Step-by-step explanation:
It's a 1 : 3 ratio so the answer should be 7
Answer:
let's work this out backwards
6:00-10 minutes to get home
5:50-3 hours spent volunteering
2:50-30 minutes to get to food bank
2:20
You need to leave for the food bank at the latest 2:20.
Answer:
Infinite series equals 4/5
Step-by-step explanation:
Notice that the series can be written as a combination of two geometric series, that can be found independently:
The first one: is a geometric sequence of first term () "1" and common ratio (r) " ", so since the common ratio is smaller than one, we can find an answer for the infinite addition of its terms, given by:
The second one: is a geometric sequence of first term "1", and common ratio (r) " ". Again, since the common ratio is smaller than one, we can find its infinite sum:
now we simply combine the results making sure we do the indicated difference: Infinite total sum=
Let C be the center of the circle. The measure of arc VSU is , so the measure of the minor arc VU is . The central angle VCU also has measure .
Triangle CUV is isosceles, so the angles CVU and CUV are congruent. The interior angles of any triangle are supplementary (they add to 180 degrees) so
UT is tangent to the circle, so CU is perpendicular to UT. Angles CUV and VUT are complementary, so
So finally,
degrees.
