It would cost $16.65
$9.99 divided by 3 is 3.33 so we know one pizza costs $3.33. So now if I multiply the 5 pizzas times the cost of one I get 5 x $3.33 = $16.65
Step-by-step explanation:
Convert 34 Decimeters to Kilometers (dm to km) with our conversion calculator and conversion tables. To convert 34 dm to km use direct conversion formula below.
34 dm = 0.0034 km.
You also can convert 34 Decimeters to other Length (popular) units.
Answer:
33600 m²
Step-by-step explanation:
The top and bottom horizontal sides are parallel, so this is a trapezoid with bases DC and AB. The height is BC.
area of trapezoid = (a + b)h/2
where a and b are the lengths of the bases, and h is the height.
We need to find the height, BC.
Drop a perpendicular from point A to segment DC. Call the point of intersection E. E is a point on segment DC.
DE + EC = DC
EC = AB = 360 m
DC = 600 m
DE + 360 m = 600 m
DE = 240 m
Use right triangle ADE to find AE. Then BC = AE.
DE² + AE² = AD²
DE² + 240² = 250²
DE² = 62500 - 57600
DE² = 4900
DE = √4900
DE = 70
BC = 70 = h
area = (a + b)h/2
area = (600 m + 360 m)(70 m)/2
area = 33600 m²
Answer:
1. -3x^2 + 13x + 5
2. 10y^2 - 7
Step-by-step explanation:
1. (7 + 4x - 8x^2) - (2 - 9x - 5x^2)
Combine Like Terms —›
(7) - (2) = 5
(4x) - (-9x) —› (4x) + (9x) = 13x
(-8x^2) - (-5x^2) —› (-8x^2) + (5x^2) = -3x^2
-3x^2 + 13x + 5
2. (2y^2 + 5xy - 8) - (5xy -1 - 10y^20)
(2y^2) - (-10y^2) —› (2y^2) + (10y^2) = 10y^2
(5xy) - (5xy) = 0
(-8) - (-1) —› (-8) + 1 = -7
10y^2 - 7
Definitions:
Perpendicular bisector: A line that bisects (split into two equal parts) a line segment at a right angle (90°)
Angle bisector: A line that bisects a angle.
Median of a triangle: Line segment drawn from a vertex to the middpoint of the opposite side to the vertex.
Altitude of a triangle: Perpendicular segment form a vertex of a triangle to the opposite side.
a) With the given information you can describe FI as:
Median of triangle FGH:
Line segment drawn from a vertex (F) to the middpoint of the opposite side to the vertex (GH). The two marks in red indicates that the segments have the same measure (then the point I is the middpoint of the side GH.
Theres is not indication of a perpendicular angle, or a bisection of the angle. Then you can not describe FI as any of the other options.
