Answer:

Shape 3

Step-by-step explanation:

It can be seen in the figure that the plane is perpendicular to the base and the top of the elliptical cylinder, therefore the shape formed must have a straight line in its lower and upper sides; this discards shapes 1 and 4. Also, this perpendicularity makes parallel the left and the right side of the shape formed, dicarding shape 2.

<u>Answer</u>

-5/3, -1,  0.7,  √2,   √5


<u>Explanation</u>

√5 = 2.236

-1 ⇒ this is less than 1.  

-5/3 = -1.666667    this is less than 1.  -5/3 < -1

0.7 > -1

√2 = 1.414        ⇒     √5 > √2

Arranging them from the least to the greatest;

-5/3, -1,  0.7,  √2,   √5

almond37 [142]

Answer:

3.

Step-by-step explanation:

Let's break it down.

Sparkles used 12 balloons total to make 4 balloon animals. Divide 12 by 4, and you will get 3.

What I did for part 2 of the equation, is I multiplied 4 and 5 by 3 to ensure the variable matched my calculations. 4x3 is 12, and 5x3 is 15. add 12 and 15, and you will get 27 total balloons.

A number is increased by 50% and then another 25%. By how much is it increased in total?
blsea [12.9K]

Answer:

87.5 percent

Step-by-step explanation:

when you have to increase a number by 50 percent you are multiplying it by 1.5

later when you increase the number by 25 percent you multiply it by 1.25

you can multiply 1.5 by 1.25 to get your answer

1.5 * 1.25 is 1.875

so the percent increase is 87.5 percent
