Answer:
14>3
Step-by-step explanation:
you would need to turn the 3 in the parenthesis into a fraction which would result in 9/3. 2/3 - 9/3= -7/3
Multiply the 7/3 by 6 and by what I have always been taught, you only multiply the top of the fraction. This would leave it to be 42/3 which would be known as 14.
So therefore the answer would be 14>3
Answer:
$84.87
Step-by-step explanation:
The mover costs $69
23% of 69 is $15.87
add the two together to get $84.87
(or just multiply 69 by 1.23)
Answer:
Step-by-step explanation:
<u>Area formula:</u>
<u>The height is:</u>
- h = (x + 2)sin 45° = √2(x + 2)/2
<u>Substitute the area value an set an equation:</u>
- 4√2 = (2x - 3)√2(x + 2)/2
- (2x - 3)(x + 2) = 8
- 2x² + x - 6 = 8
- 2x² + x - 14 = 0
- D = 1 + 4*2*14 = 113
- x = (-1 + √113)/4 = 2.41 (rounded)
Note. the second root ignored as negative
Volume of a cone can be found using the equation 1/3 π r² h (or π r² h / 3)
r = 11
h = 4.5
π ≈ 3.14
(1/3) (3.14) (11²) (4.5) =
(1/3) (3.14) (121) (4.5) =
(1/3) (3.14) (544.5) =
(1/3) (1709.73) = 569.91
569.91 rounded to the nearest tenth is 569.9 so your answer would be 569.9 in³
