1/2 a 6 ounce glass is 3 ounces. He drinks 3 ounces in 2/3 of an hour.
3/2 = 1.5. He drinks 1.5 ounces in one third of an hour. 1.5 * 3 = 4.5
C. 4.5 ounces in one hour
0.5 will be rounded to 1.0
1.2 will be rounded to 1.0
1.7 will be rounded to 2.0
3.4 will be rounded to 3.0
Answer:
a = 1.5
VW = 9 ft
Step-by-step explanation:
Since the tangent lines connect both circles, we know that the line VU and VX are congruent (equal). Thus, we can set them equal to each other and solve for a:
a + 4 = a² + 0.25 Set equal
a² - a = 3.75 Isolate a values
a² - a + 0.25 = 3.75 + 0.25 Complete the square
(a + 0.5)² = 4 Factor
a + 0.5 = 2 Simplify
a = 1.5
Now we need to calculate VW, but thats easy because its equal to TV, and since we know a, we can just plug it in:
((1.5) + 7.5) ft
9 ft
Isn't it B because if y was squared, y^2, and the quotient of 28 and 7 was decreased from it, then wouldn't it look like the expression of B? (This is because the quotient of 28 and 7 is represented by 28/7, because fractions actually mean to divide). I hope this helps! (But I'm a 6th grader, so at least I hope someone agrees with me!) :D
