Total number of yards of ribbon available =  25 yards.

Number of yards of fabric available  = 30 yards.

Number of yards of ribbon a child need  = 1.75 yards

Number of yards of fabric a child need = 2.8 yards.

<em>Total number of children participate in the activity for 25 yards of ribbon = 25/1.75 = 14.28 approximately 15 children.</em>

<em>Total number of children participate in the activity for 30 yards of fabric = 30/2.8 = 10.7 approximately 11 children.</em>

<h3>Therefore, maximum 11 children can participate in the activity because each child required both 1.75 yards of ribbon and 2.8 yards of fabric .</h3>

13/35 because you have to find the common denominator which would be 35 and in order to get 7 to 35 you have to multiply the whole thing by 5 making the fraction equal 15/35 and you have to multiply the other fraction by 7 making it 7/35 add the two together which would equal 22/35 so to make that 35/35 it would have to be 13/35

Grade 9 maths!!! Due tonight
Artyom0805 [142]

Answer:

a. 7 by 21

b. a(-12, 2), b(-12, -5), c(9, -5)

Step-by-step explanation:

AD is 3 times the length of AB. X can be the length of AB. Then 3x would be the length of AD. The perimeter is 56, which would also be 3x + x + 3x + x which is 8x. This gives us 8x = 56, meaning that x is 7, or the length of AB is 7. Because AD is 3 times the length of AB (which is 7), AD = 21. Therefore, the dimensions of the rectangle ABCD is 7 by 21.

Coordinates of A have to be 21 units away from D since AD = 21. It goes in the left direction, meaning that 21 is subtracted from 9 (since this is a horizontal edge involving x coordinates) while the y value remains the same. The result is (-12, 2). For coordinate B, it has to be 7 units away from A downwards since AB = 7. This means that you subtract 7 from 2 (involving only the y coordinates), resulting in (-12, -5). For coordinate C, it has to be 21 units from B since BC = AD = 21.  Because C is right compared to B, you have to add 21 to -12 (involving only the x coordinate) resulting in (9, -5).

What value of c is the rational expression below equal to zero? x-4/x-6
RSB [31]

Answer: x=4

Steps: (I am assuming your question has a typo in it and by "c" you meant "x")

The rational expression equals zero

\frac{x-4}{x-6}=0

only when the numerator equals 0 (the denominator cannot ever be zero):

x-4 = 0 \\x = 4

and that happens only for x=4
