Recall: distance = rate times time.
To determine how far apart the two cars will be after four hours of travel, subtract the sum of the distances traveled from 200 mi:
Distance apart after four hours = 200 mi - (40 mph)(4 hrs) - (35 mph)(4 hrs)
= 200 mi - 160 mi - 140 mi = -100 mi
The wording of your question implies that the cars will not yet have met after four hours of travel. This negative result is absurd. Please ensure that you have copied down the problem completely and accurately.
Answer:
The first, second to last and last stements are true
Step-by-step explanation:
You times 8 by the percentage as
e.g 8 x 1.50 = 12 is the same as marked up by 50%
e.g 8 x 1.70 =13.6 is the same as marked up by 70%
Answer:
D. Place the triangle on a coordinate grid such that QR lies on the x-axis and PQ lies in the y-axis
Step-by-step explanation:
A midsegment of the triangle is the line segment the connects the midpoints of two sides of the triangle. This midsegmet is parallel to the base.
Constructing a triangle with two sides over the x-axis and y-axis respectively makes it easier to verify that the midsegment is half the base.
So, it's D. The best option.
Answer:
Length of sides of poster = 2 Ft
Length of sides of box = 2.41 Ft
Since the box has a longer side than the poster, the poster will lie flat when placed in the box.
Step-by-step explanation:
In order to determine if the poster will lie flat in the box or not, we will determine the length of the sides of the poster and the box, if the length of the side of the square poster is smaller than that of the box, it will lie flat. This is calculated as follows:
Area of poster = 4 square feet
Area of poster = (Length)²
4 = (Length)²
∴ Length = √(4)
Length of poster = 2 Ft
Volume of box = 14 cubic feet
Volume of box = (Length)³
14 = (Length)³
∴ Length = ∛(14)
Length = 2.41 Ft
∴ Length of sides of poster = 2 Ft
Length of sides of box = 2.41 Ft
Since the box has a longer side than the poster, the poster will lie flat when placed in the box.
The perimeter of the school crossing sign is 102 inches
length of each side = ?
in the question number of sides is not mentioned, so the answer may vary for the length of each side. if there is 5 sides divide 102 by 5, we get 20.4 answer so in case of 5 sides length of each side is 20.4 inches. if there is 4 sides divide 102 by 4 and we get 25.5 inches answer for the legnth each side.
