Answer:
Square, rectangle and trapezoid are use to make an octagon.
Step-by-step explanation:
We need to find how to make an octagon with 3 smaller shapes. We can make an octagon using three shapes : rectangle , square and trapezoid.
Square is a quadrilateral with four sides equal .
Rectangle is a quadrilateral with opposite sides equal .
Trapezoid is a quadrilateral with one pair of opposite sides parallel.
Place a square in the central/middle of the octagon. Then place two rectangles on the top and bottom of the square and finally complete the octagon by placing two trapezoids on the left and the right of the square.
Answer:
73.9
Step-by-step explanation:
multiply 5.50 by 8 and 14.95 by 2
EDIT: then add the products together
Answer:
option D
Step-by-step explanation:
In the given graph 4 lines have been used.
(1) First one is x = 0
(2) second is y = 0
(3) Third line is y = -x + y
(4) Fourth line is y = x + 2
Now we have to tell the inequalities which form the colored area.
(1) y axis is a solid line with colored area on the right side so y ≥ 0 is the inequality.
(2) x axis is a solid line with colored area upwards so x ≥ 0 is the second inequality.
(3) Colored area is below the solid line y = -x + y so inequality will be y ≤ ( -x +4 ).
(4) Colored area is below the dotted line y = x + 2 so the inequality representing the colored area will be y< x + 2
System of inequalities will be x ≥ 0, y ≥ 0, y < x + 2 and y ≤ (-x + 4)
Therefore, option D is the answer.
Answer: D
Step-by-step explanation:
P=mgh
Answer choices:
H=P-mg
H=pg/m
H=p/mg
H=P+mg
Answer:
The answer is H = p/mg.
Step-by-step explanation:
Give the variables actual values, and then solve. Let's say:
H = 4
G = 3
M = 2
The equation P = mgh tells us to multiply m x g x h. 3 x 2 x 4 = 24, so P = 24.
Now our values are:
P = 24
H = 4
G = 3
M = 2
So now we have to find which equation is equal to 4, or the value we have substituted for H.
So let's test the answer choices out.
H = P - mg. This would say that 4 = 24 - 2 x 3. 2 x 3 = 6, and 24 - 6 is 18. 18 is not equal to 4, so H = P - mg is not the correct answer.
H = pg/m. This would say that 4 = 24 x 3 divided by 2. 24 x 3 is 72, and 72 divided by 2 is 36. 36 is not equal to 4, so H = pg/m is not the correct answer.
H = P + mg. This would say that 4 = 24 + 2 x 3. 2 x 3 is 6, and 24 + 6 is 30. 30 is not equal to 4, so H = P + mg is not the correct answer.
H = p/mg. This would say that 4 = 24 divided by 2 x 3. 2 x 3 is 6, and 24 divided by 6 is 4. 4 is equal to 4, so H = p/mg is the correct answer.
This formula of substituting the variables for values can work for any value. Just do yourself a favor and make it easy for yourself, by not choosing values like 13045. That's just a waste of time.
