Answer:

The box is 7.5 in long.

Step-by-step explanation:

Calculate the total surface area of the sides of this box (neglecting the ends).

If the base is 3" by 3" and the length of the box is 6", then the total surface area (without ends) is 4 times 3" by x, or  12x in².  80% of this "lateral surface area" is 0.80(12x in²), or 9.60x in° and this 9.60x in² represents the surface area covered b y the label.  That label surface area is 4(3 in by 6 in), or 72 in²

Equating 9.60x in² and 72 in² and solving for x yields  x = (72 in²) / (9.60 in²:

x = 7.5 in

The box is 7.5 in long.

The airplane in the scale drawing has a wingspan of a feet and a tail span of b feet. If the tailspin in the drawing is 2 inches
xeze [42]

Correct answer is: actual wingspan of airplane is 6 inches.

Solution:-

We are given that wingspan is 'a' feet and tail span is 'b' feet in a scale drawing.

And we are also given that tail span is 2 inches that is b=2 inches and \frac{a}{b}=3

Let us plugin the b value in above equation.

\frac{a}{2}=3

Multiplying with 2 on both sides.

a=3X2=6 inches.

Hence actual wingspan of airplane is 6 inches.

Which inequality is true use the number line to help​
Nata [24]

Answer:

-3 1/2 > -4.5

Step-by-step explanation:

1.5 > 2 1/2 False

1/2 > 0.5 False

-2.5 > -1.5 False

-3 1/2 > -4.5 True

1.5 > 2 1/2

1/2 = 0.5

2 + 0.5 = 2.5

1.5 is not > 2.5

1.5 < 2.5

1/2 > 0.5

1/2 = 0.5

0.5 is not > 0.5

0.5 = 0.5

-2.5 > -1.5

Negative numbers are oposite of positive numbers when using inequalities. Just as 0 < 1, -1 < 0.

-2.5 is not > -1.5

-2.5 < -1.5

-3 1/2 > -4.5

1/2 = 0.5

3 + 0.5 = 3.5

-3.5 > -4.5

mel-nik [20]

9514 1404 393

Answer:

  • 4 3-point baskets
  • 7 2-point baskets

Step-by-step explanation:

Let x represent the number of 2-point baskets Nicoli made. Then (x -3) is the number of 3-point baskets. The total number of points is ...

  2x +3(x -3) = 5x -9 = 26

  5x = 35 . . . . . . add 9

  x = 7 . . . . . . . divide by 5

  (x -3) = 4 . . . find the number of 3-point baskets

Jokic made 7 2-point baskets and 4 3-point baskets.

LekaFEV [45]

Answer: Insufficient Information

The probability of selecting a red ball, a blue ball or a white ball is unknown.
