Answer:
40 and 20
Step-by-step explanation:
- Uncle Jason's age = x
- Nephew Ralph age = y
<h3>Solution</h3>
<u>Age now:</u>
<u>Age 10 years ago: </u>
<u>Substituting x in the second equation:</u>
- 2y - 10 = 3y - 30
- 3y - 2y = 30 -10
- y = 20
<u>Then, finding x:</u>
<u>Answer:</u> Uncle Jason is 40 and nephew Ralph is 20 years old
I'm assuming that 5π3 is in fact 5π/3
convert radian to degrees:
5π / 3 = 5(180°) / 3 = 900° / 3 = 300°
Area of the circle = π r²
A = 3.14 * (6 ft)²
A = 3.14 * 36 ft²
A = 113.04 ft²
Area of the sector:
113.04 ft² * 300°/360° = 94.2 ft²
The area of the sector formed by a central angle measuring 5π/3 radian is 94.2 ft²
Answer:
84 ft^2.
Step-by-step explanation:
Use Pythagoras to find the value of h:
25^2 = h^2 + 7^2
h^2 = (25-7)(25+7)
h^2 = 576
h = √576 = 24
Area = 1/2 * 7 * 24
= 84.
6. 40 minutes (15/3 = 5 minutes/mile) - 5*8 = 40 min
7. 15,840 ft / 5 = 3.168 ft
Answer:
the equation would be b. y=2x-3.
