Mathematics

When adding 10 to any two digit number, increase the left digit by 1. For example 20+10= 30. 55+10=65. If a problem says 10+ (a number), you can reverse the order the numbers are in because of the commutative property of addition. Example: 10+50 eqauls 50+10. Both equations equal 60. Also, Rodney would have 39 pieces of fruit since 20+19 is 39.

It depends. Multiples of 10 are:
10, 20, 30, 40, 50...........
And a 2 digit number can be anything between 10 and 99.

To comment: Rodney would have 39 pieces of fruit.

The weight of water is 62 1/2 lb per cubic foot. Water that weighs 350 lb will fill how many cubic​ feet?
valentinak56 [21]

The question is worded incorrectly.  It should say the DENSITY of water is 62 1/2 lbs per cubic foot.  Divide the weight by the density to get volume.

(150 lbs) / (62.5 lbs/ft3) = ? ft3 (the two 3's are exponents. so it'd be ft then an exponent of 3.)

Find the area of the shaded regions of the following figures. Will Give Brainliest!! Answer ASAP
Butoxors [25]

Answer:

Rectangle 1 area: 53 units squared

Shape 2 area: 43.75 units squared

Step-by-step explanation:

Shape 1:

We need to find the area of the two triangles in this rectangle and subtract it from the total area of the rectangle.

Total area of the rectangle:

13 * 5 = 65

Area of triangles (they are congruent):

1/2 * 4 * 3 = 6

6 * 2 = 12

65 - 12 = 53

The area of the shaded part is 53 (I don't know what your unit of measurement is. Just say units.)

Shape 2:

First, let's find the area of the parallelogram at the top.

10 * 3 = 30

Now, let's find the area of the rest of the shape. Triangle first...

1/2 * 4 * 1.5 = 3

Now, the rectangle and the tiny triangle we can section out at the end:

7 * 1.5 = 10.5 + 1/4 (Triangle) or 0.25 = 10.75

Total area: 10.75 + 3 + 30 = 43.75

Is the answer 24 ?? Someone please help
ELEN [110]
Yes the answer is 24 cm2
because the width is 4 cm then 2 width = 2(4) = 8 cm
perimeter = 20 cm
20-8=12 cm
so 12 cm left is 2 length then the length is 12/2= 6;cm
that's why the area is 4*6= 24 cm2
