Answer:
5/3
Step-by-step explanation:
We need to rewrite the equation in slope intercept form
y =mx +b where m is the slope
-3x-5y = 7
Add 3x to each side
-5y = 3x+7
Divide by -5
y = -3/5 x -7/5
The slope of this line is -3/5
Perpendicular lines have slopes that are negative reciprocals
-1 / (-3/5)
5/3
The slope of the perpendicular line is 5/3
The directions on a sewing pattern say to cut an extra 15% of fabric to account for error.
Chloe needs 0.75 yardof fabric to make a skirt, and she cuts 0.1125 yard.
Did Chloe cut the correct amount of fabric? Why or why not?
9514 1404 393
Answer:
no; the yardage should be more than 0.75 yards
Step-by-step explanation:
A value that is 15% more than 0.75 will be a number that is greater than 0.75. The number 0.1125 is much less than 0.75, so cannot be the correct amount of fabric.
Chloe did not cut the correct amount.
(the correct amount is 0.8625 yards)
_____
Additional comment
Often, all that is needed for answering a multiple choice question properly is ...
a) an understanding of what the question is asking
b) comprehension of what the answer must look like.
Here, the directions are saying to cut more than 0.75 yards. The result will be a value that is more than 0.75 (and less than 1).
The value 0.1125 yard is 15% of 0.75 yard. The cut amount should be that much in addition to 0.75 yard: 0.75 +0.1125 = 0.8625 yard.
Tickets for a school concert were priced at $7 for students and $9 for non-students. There were twice as many student tickets sold as non-student tickets for a total of $3,220.
Answer:
number of non students=140, students=280
Step-by-step explanation:
let non students be x.
so according to condition, non students=x*9
students=2x*7
now,
2x*7+x*9=3220
so, x=140

When converted to a household measurement, 9 kilograms is approximately equal to a
Answer:
D) 19.8 lbs
Explanation:
1kg in household measurement is equal to 35.274 ounces. 35.274*9=317.466 ounces.
1kg is also equal to 2.205 lbs. 9*2.205=19.8416
9 kg is also equal to 9000 grams, but grams are not a part of the household measurement system
a) 9000 grams. b) 9000 ounces. c) 19.8 ounces. d) 19.8 pounds.

How would Newton’s second law of motion impact the fitness routine of someone who is significantly overweight? Is there any type of fitness activity that a significantly overweight person could do where Newton’s second law of motion would not be a factor?
9514 1404 393
Explanation:
Newton's second law relates force, mass, and acceleration. For the same acceleration, more force is required to change the motion of more mass.
(a) Any fitness routine where velocity changes are involved will be impacted by Newton's second law. A significantly overweight person would have to expend significantly more energy to achieve the same changes of motion in the same period of time.
(b) Any fitness routine in which changes of speed or direction at a specific rate are not required will not be impacted by Newton's second law. These might be Tai Chi routines, weight lifting, or any other routines in which speed of completing a cycle of motion is not a factor.

Which equation represents a line which is parallel to the line Y= 1/2 X +3 1. y-2x=-5 2. 2x+y=-6 3. x-2y=2 4. x+2y=4
Answer:
x-2y=2.
Step-by-step explanation:
1) if to re-write all the given equations of the lines, then
y=2x-5; y=-2x-6; y=1/2x-1; y= -1/2x+4.
2) y=1/2x-1 only is parallel to the given y=1/2x+3.
