Mathematics

Alex Ar [27]2 years ago

Step-by-step explanation:

You want to set one of the equations equal to either x or y. For this, I put x+y=-2 equal to y which would be y=-x-2. Then you plug this in to the other equation for y. This would give you 5x+2(-x-2)=2. When you factor the two into the parenthesis, combine like terms, and keep the x values on ones side and the other numbers on the other side, you get 3x=6

naomi's fish is 40 millimeters long. her guinea pig is 25 centimeters long. how much longer is the guinea pig than her fish
horrorfan [7]
Hi there!

The correct answer is 6.25 times.

This is how you get there:

1) First off, you are going to need to have the same unit (either cm or mm). I used millimeters for this problem. 25cm=250mm

2) This next part is very easy to get wrong. You need to figure out what you are dividing, and by what. Simply look at the problem. <span><em>"How much longer is the guinea pig than her fish?" </em>This shows what numbers you should be getting. The guinea pig is 250mm long, where the fish is only 40. This means that her guinea pig should be larger. 250÷40=6.25

If you did this problem the other way, you would've ended up with .16. If you put the sizes into perspective, you will notice that this is highly unlikely.

I hope that I have been able to simplify this problem for you!

△RQS is similar to △TQU by the AA similarity postulate. What is the measure of angle R ?
natta225 [31]

Answer:

  60°

Step-by-step explanation:

The sum of angles in a triangle is 180°.

  ∠R + 88° + 32° = 180°

  ∠R = 60° . . . . . . subtract 120° from both sides of the equation

Anna71 [15]

Answer:

Actual volume=3,773,000 in³

Step-by-step explanation:

Scale 1:35

Actual Width=Model Width×Scale factor=(2×35)=70 inches

Actual Length=Model Length×Scale factor=(11×35)=385 inches

Actual Height=Model Height×Scale factor=(4×35)=140 inches

Actual volume =(Base Area×Height)=Length×width×height=(385×70×140)=3,773,000 in³

Actual volume=3,773,000 in³
