Answer:
1.78 miles
Step-by-step explanation:
3/4 = .75 of a mile + 1.3 = 1.78
The answer is 2.05.
you can make the fraction into a decimal, 3/4=0.75, then you just add 0.75 to 1.3.
Scale shows weight = 193
Weight of assistant = 135
Weight of dog = x
x = 193 - 135
x = 58
The dog weighs 58 pounds.
17y = 85x
A) Yes
B) No
C) 5
D) 1/5
2) Determine whether the relationship is a direct variation.
X : 3, -1 , -4
Y : -6, 2, 8
A) yes
B) No
3) Is the relationship shown a direct variation? (it's not absolute value is a table chart)
| X | Y |
| -2 | 5 |
| 1 | 3 |
| 4 | 1 |
A) yes
B) No
4) Determine whether the relationship is a direct variation.
------------------------------
| X | 6 | 9 | 17 |
-------------------------------
| Y | 13.2 | 19.8 | 37.4 |
-------------------------------
A) yes
B) no
5) Determine which equation does NOT represent a direct variation.
A) 6x - y = 0
B) y = 4x + 1
C) y = -2x
D) y = 1/3x
6) (multiple answer pick 2) Tell whether the equation represents a direct variation. If so identify the constant of variation. y + 3x = 0
A) Yes
B) No
C) -3
D) 1/3
E) 3
1.) The answer is (B) No, because direct variation is written as y = kx, but the problem was not written that way.
2.) Answer: Yes; if you write x = ky, you will find that each x value given multiplied by a common k equals a corresponding y value.
3.) Answer: No; each x value does not multiply by a constant k to get the y values.
4.) Answer: Yes; each x value multiplies by 2.2 to get each corresponding y value.
5.) Answer: B; this is the only one that isn't or can't be written in y = kx form.
6.) Answer: Yes & -3; y + 3x = 0 can be written as y = -3x, which is a direct variation equation. The constant is just the -3.
1) b
2) no
3) c
4) a
Answer:
5/16
Step-by-step explanation:
Answer:
Chubby ran a distance of 6,283 m
Step-by-step explanation:
The length of one run is simply equal to the circumference of the circle
Mathematically, C = pi * d
C = 22/7 * 20 = 62.83 cm
So if one rotation is a distance of 62.83 cm, then 100 rotations will be a distance of;
62.83 * 100 = 6,283 m
