We just multiply the scale to the dimensions
2 in to original is: 2×40= 80 cm
or do proportions:
\frac{2}{x}=\frac{1}{40}
=\frac{2*40}{1}=x
=80 cm=x the original dimension.
Same thing to the other side.
1.5×40=60 cm
or proportions again:
\frac{1.5}{y}=\frac{1}{40}
\frac{1.5*40}{1}=y
60 cm=y 
60 cm is the original dimension
80 cm times 60 cm ORIGINAL DIMENSION

Equation practice with angle addition
Triss [41]

Answer:

36 degrees

Step-by-step explanation:

since, m<AOB is a right angle, we shall just create an equation:

M<AOB+M<BOC=90 degrees

Substitute: 6z-12+3z+30=90

Solve: 6z+3x=9z

-12+30=18

so, 9z+18=90 degrees

           -18  -18

9z=72

z=8

So if z=8, then we should fit it so that it matches measure of AOB.

6z-12

6 times 8=48

48-12= 36

A large mixing tank currently contains 225 225 gallons of water, into which 5 5 pounds of sugar have been mixed. A tap will open
kkurt [141]

Answer: Hello mate!

you put every number twice, I will consider that in this problem we have:

225 gallons of water initial with 5 pounds of sugar. then each minute you add 20 gallons of water and 4 pounds of sugar.

the concentration is defined as pounds of sugar divided by the gallons of water. The gallons of water are 225 initially and 20 per minute, this is written as 225 + 20tt, where t is the minutes. The pounds of sugar is 5 + 4 per minute, then this can be written as 5 + 4t

C(t) = \frac{5 + 4t}{225 + 20t}

this is the equation that describes the concentration in pounder per gallon after t minutes.
