A sweater is marked down 30% off the original price. The original price of the sweater was $42. What is the sale price of the sweater?
Answers
You take the original price and multiply it by .3(30%). Then you’ll take that answer, which is 12.6 and subtract it from 42
42x.3=12.6
42-12.6=$29.40

3. Write the equation of a line in slope-intercept form that passes through the following points: (3,-8) and (-12,2).
Answers
Answer: Y=-2/3x-6
Step-by-step explanation:
we subtract both y1 x1 and y2 x2:
2-(-8)
-12-3 =
10/-15 = -2/3 (Equivalent fraction)
y=-2/3x + b
we need to plug in the first point which is (3.-8)
-8=-2/3(3) the 3 cancels out and we are left with -8=-2
we subtract and get -6 which is our Y intercept

Traveling along a river, a man in a row boat loses his hat when he passes under a bridge. In 15 minutes, he realizes that he lost his hat, and rows his boat the other way until he is able to retrieve his hat 1 km away from the bridge. What is the speed of the river's current?
Answers
Answer:
The speed of the current is 33.33 meter/minute.
Step-by-step explanation:
Let the speed of the boat in still water is x km per minute and the water is r km per minute.
The speed of the boat in downstream is (x + r) km per minute and in upstream is (x - r) km per minute.
First, the man was moving in upstream, because the hat was retrieved 1 km away from the bridge.
After losing the hat the man traveled 15 minutes upstream, hence he went 15(x - r) km far from the bridge.
After 15 minutes he was coming back to collect his hats.
Let, he has traveled downstream for t minutes to get his hat.
Hence, t(x + r) = 15r + tr + 15(x - r) or, tx = 15x or, t = 15.
Again, 15r + 15r = 1 km or, r = 1/30 km = 1000/30 =33.33 meters.
Answer:
2 km/h
Step-by-step explanation:
You want to know the speed of the river's current if a man loses his hat in the river and continues to row downstream for 15 minutes before returning upstream to retrieve his hat, 1 km downstream from where he lost it.
ReferenceSince the hat is moving with the current, the boat is essentially in "still water" relative to the hat. The distance rowed in 15 minutes, relative to the hat, is exactly the distance that must be rowed to retrieve the hat. That is, the return trip takes 15 minutes as well.
The man is away from his hat for 1/2 hour, in which time the current has moved it downstream 1 km. Hence the speed of the current is ...
(1 km)/(1/2 h) = 2 km/h
The speed of the river's current is 2km/h.
__
Additional comment
Interestingly, it does not matter if the original direction is upstream or downstream, nor does it matter how fast the man is rowing (as long as his speed is not zero).

Answers
Answer: 16 degrees
Step-by-step explanation:
Since m||n, then t is a transversal.
Therefore, you can see that x = 16 degrees
Answer:
16°
Step-by-step explanation:
Given that m and n are parallel, we know that the angles on this transversal are equal. Using the Alternate Exterior Angles Theorem we can see that x=16 because 16 degrees is the angle measurement of the alternate exterior angle.

please help! How can this be solved?
Answers
a)
Given
perimeter of the rectangle :36
case 1
given length :9
perimeter =2(l+w) l= length,w =width
36 = 2(9+w)
36 = 18+2w
36 -18 =2w
w = 9
area = length * width
= 9*9
= 81 m^2.
case 2
given length :10
perimeter =2(l+w) l= length,w =width
36 = 2(10+w)
36 = 20+2w
36 -20 =2w
w = 8
area = length * width
= 10*8
= 80m^2.
case 3
given length :11
perimeter =2(l+w) l= length,w =width
36 = 2(11+w)
36 = 22+2w
36 -22 =2w
w = 14
area = length * width
= 11*14
= 154 m^2.

Answers
Answer: 8/35 square yards
Step-by-step explanation:
The formula to find an area of a rectangle is L * W (length * width). Here your length would be 4/7 yards, and your width would be 2/5 yards, so plugging it into the formula would be 4/7 * 2/5 = 8/35 square yards.
