7 miles:2.5 hours
10 miles:? hour
10×2.5÷7=25/7. As a result, It took him 25/7 hours or 3 4/7 hours to ride 10 miles. Hope it help!
Answer:
185
Step-by-step explanation:
cause if you add up 80+65+40 right?
Answer:
121°
Step-by-step explanation:
- We have been given a chord and tangent to a circle, and also a minor arc measure that is equal to 118°
- We know that; An angle formed by a secant and tangent of circle is half of the measure of intercepted arc.
Therefore; ∠ x = 1/2 mABC
- We can find intercepted arc by subtracting minor arc measure from 360 degrees because minor and major arcs add up to 360 degrees.
Thus;<em> 360° - 118° = 242°</em>
<em>Using the formula; ∠ x = 1/2 mABC</em>
<em>Then; d = 242/2</em>
= 121°
6)
91 is a composite number because it's divisible by 7 and 13
7)
477 is divisible by 3 and 9, since the sum of its digits (18) is divisible by 3 and 9 ( or the sum is a multiple of 3 and 9) .Not divisible by 6
8)
348:is divisible by 4 because the last 2 digits (48) are a multiple of 4
348:is NOT divisible by 5 because the last digit is neither 5 nor 0
348:is divisible by 6 because it's divisible by 2 and also by 3
9)
23624 is divisible by 8 because te last 3 digits (624) are divisible y 8
(624/8 =78)
None of the others are divisible by 8
10) A number is divisible by 6 IF IT'S DIVISIBLE BY 2 AND BY 3:
213 NO
468 is divisible by 2 since the last digit is divisible by 2. It's also divisible by
3 since the sum of its digits [18] is divisible by 3, hence 468 is divisible by 6
621 it's divisible by 3 but NOT by 2, then it's not divisible by 6
Pretty sure the answer is SAS because SSS only work on right triangles and this triangle has an angle
