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
cake tin: 25 cm in diameter
convert mm to cm.
1 cm = 10 mm
600mm * 1cm/10mm = 60cm
500mm * 1cm/10mm = 50cm
Area of oven tray = 60cm * 50cm = 3,000 cm²
Area of cake tin = 3.14 * (25cm/2)² = 3.14 * (12.5cm)² = 3.14 * 156.25cm² = 490.625 cm²
3,000cm² ÷ 490.625cm² = 6.11 or 6 cake tins can fit on the oven tray at one time.

Answers
Answer:
5. a,c,b
6. a,b,c
7. v,z,y,w,x
Step-by-step explanation:
5. Given are the measure of sides as 28,17 and 15. The corresponding angles are 'a', 'c' and 'b'.
Using the conjecture: The angle opposite to the greatest side is largest.
Thus for the sides 28,17 and 15. The corresponding angles 'a', 'c' and 'b' are in order from greatest to least.
6. Given are the angles 30, 72 and 75( angles of an isosceles triangle).
Using the conjecture: The angle opposite to the greatest side is largest.
We observe
'a' is corresponding to angle 75°
'b' is corresponding to angle 72° and
'c' is corresponding to angle 36°
Thus a,b,c are the order from greatest to least.
7. Given
'v' is corresponding to angle 122° [180-(30+28)]
'w' is corresponding to angle 42°
'x' is corresponding to angle 34°
'y' is included in three dimensional angle
'z' is included in three dimensional angle
Such that
Thus the order from greatest to least is v,z,y,w,x

if you wanna know how to solve this
here is how:
Simplifying 2p + 7 = 21 Reorder the terms: 7 + 2p = 21 Solving 7 + 2p = 21 Solving for variable 'p'. Move all terms containing p to the left, all other terms to the right. Add '-7' to each side of the equation. 7 + -7 + 2p = 21 + -7 Combine like terms: 7 + -7 = 0 0 + 2p = 21 + -7 2p = 21 + -7 Combine like terms: 21 + -7 = 14 2p = 14 Divide each side by '2'. p = 7 Simplifying p = 7
8 + (-2)
-4 + (-2)

Answers
8 + (-2) = 6
-4 + (-2) = -6
-2 + 8 = 6
Since the third option equals -6, the answer would be: -4 + (-2).

let’s create another system of equation.
Let a = 4
and Let b = -3
First equation
=> Let’s pick any numbers to be used. Let’s have number 5
=> 5a + 5b
=> 5 (4) + 5 (-3)
=> 20 + (-15)
negative and positive is equals to negative
=> 20 – 15
=> 5 (this the first value of our equation, let this be the value of X)
Second
=> Pick another number, Let’s have 6
=> 6a + 6b
=> 6 (4) + 6 (-3)
=> 24 + (-18)
=> 24 – 18
=> 6 (this is the value of our second equation, let this value be Y)
Now, we have (A, B) = (4, -3) and (X, Y) = (5,6)
Answer:
A linear equation can be written in several forms. "Standard Form" is #ax+by=c# where #a#, #b# and #c# are constants (numbers).
We want to make two equations that
(i) have this form,
(ii) do not have all the same solutions (the equations are not equivalent), and
(iii) #(4, -3)# is a solution to both.
#ax+by=c#. We want #a#, #b# and #c# so that
#a(4)+b(-3)=c# (This will make (i) and (iii) true.)

add what you can
21+5+2.75+4+5/6+5/8=

add the fractions by making denom same
5/6+5/8=20/24+15/24=35/24=1 and 9/24=1 and 3/8
28.75+1 and 3/8=29.75+3/8
that is how many barels total
times 205 since that is how many litesr in each bottle
205 times (29.75+3/8)=
205*29.75+205*(3/8)=
