Answer:
Step-by-step explanation:
7 lenthii=38 inches, 10 lenthii=410
410-225.3=184.7
184.7+38=222.7 222.7+38=260.7
260.7- 4 lenthii=225.3
The answer would be x = -3
The triangle that is formed by AMB is a 45 45 90 triangle, so meaning the legs are equal. so in can be concluded that AD = MD, since M is the midpoint of CD, then CD = 2AD
CD = 2(6) = 12 cm
so the perimeter is of the rectangle ABCD is
P = 2l + 2w
P = 2(6) + 2(12)
P = 12 + 24
P = 26 cm
6.5 because you instantly take $9.50 away from $55. After you get that answer, you will have 45.5. Then divide 45.5 by 7 which will give you 6 and a half hours.
Answer:
40 marbles.
Step-by-step explanation:
Given:
Box A can hold 10 marbles.
Box B is double the height of Box A, four times the length of Box A, and half the width of box A.
Question asked:
How many marbles can Box B hold?
Solution:
Let volume of box A =
Let volume of box B =
Now, suppose:
Length of box A =
Breadth =
Height =
So, volume of box A,
As given, Box B is double the height of Box A, four times the length of Box A, and half the width of box A.
So, Length of box B =
Breadth =
Height =
Volume of box B, =
By dividing volume of box A with volume of box B:
By cross multiplication:
That means volume of box B is 4 times volume of box A;
∵ Box A can hold = 10 marbles
∴ Box B ( 4 times of box A ) can hold =
Therefore, Box B can hold 40 marbles.
