The oven tray is 600mm by 500mm. A cake tin is 25cm in diameter. How many cake tins can jenny fit on the oven tray at one time?

Answers

Answer 1

Answer: Area of Circle= $\pi$ $r^(2)$
= $(22)/(7)$ x $( (25cm)/(2)) ^(2)$
= 490.87 $cm^(2)$

Area of Oven tray= 60cm x 50cm
= 3000 $cm^(2)$

: . # tin that can hold on bake tray= 3000 $cm^(2)$ / 490.87 $cm^(2)$ = 6.11
Thus making it logically 6.....

What does 6x +3 - 1(-3 + x) equal?

Answers

Answer:

$5x+6$

Step-by-step explanation:

$6x+3-1(-3+x) = 6x+3+3-x$ (expand the brackets)

$=5x+6$ (combine like terms)

∴ $6x+3-1(-3+x) = 5x+6$

Hope this helps :)

It would equal to 6x+5

Form a union for the following sets. K = {2, 3, 5, 8}
L = {3, 5, 7}
a. { }
b. {3, 5}
c. {2, 3, 5, 7, 8}
d. {2, 7, 8}

Answers

Union of the represented sets should include all the sets without repetition
Here is an example for substituton $A= {1,2,3} B={3,4,5} A union B = {1,2,3,4,5}$ . So, logically, the answer is c. {2, 3, 5, 7, 8}

A China cup and saucer cost 12$. The cup on its own cost 3$ more than the saucer. Form an eqaution for s and solve it. Find the cost of the cup

Answers

If the cup = S + 3
and the
saucer = S
then

(S + 3) + S = 12
2s + 3 = 12
2s = 9
s = 4.50

So by itself the saucer costs $4.50. To find the cost of the cup look to the beginning of the problem where we learned that

Cup = S + 3
cup = 4.50 + 3
cup = 7.50

So the saucer is $4.50 and the cup is $7.50...

4.50 + 7.50 = $12.00

It checks!
