Answer:

(5)(8)(14)

Step-by-step explanation:

Answer:

z = 100°

x = 40°

Step-by-step explanation:

Triangle CBD is isosceles so there are two 50°

DBC = 50°

That means BDC = 80° because 180(sum of angles in triangle) - 50 - 50 = 80

Z = 100° bc angle of straight line is 180° and 180 - 80 = 100

Now triangle ADB is also isosceles because there are two sides of equal length

So there will be 2*x + 100 = 180

x = 40°

Answer:

SA = 288 cm

Step-by-step explanation:

l = 12

w = 4

h = 6

SA = 2lw + 2wh + 2lh

SA = (2 x 12 x 4) + (2 x 4 x 6) + (2 x 12 x 6)

SA = 96 + 48 + 144

SA = 288

Answer:

Simplify 3(x+1)−5.

3x−2=3x−2

Move all terms containing x to the left side of the equation.

−2=−2 Since −2=−2 , the equation will always be true for any value of x

Step-by-step explanation:

Answer:

A=32.3

P=24.6

Step-by-step explanation:

P= 2(8.5)+2(3 4/5) = 24.6 or 24 3/5

A=3 4/5 * 8.5=32.3

Answer:

1.

perimeter: 14.6

area: 32.3

Step-by-step explanation:

convert 3 4/5 into a fraction (3.8)

then for perimeter you add all the sides

for area you multiply length x width (3.8 X 3.5)

Answer:

I believe it is because it is being transferred to kinetic energy

Step-by-step explanation:

As the puck falls, it loses potential energy and gains kinetic energy because it is now falling, which causes movement due to gravity. And as we know, kinetic energy is energy which a body possesses by virtue of being in motion

Answer:

first we have to convert mm to cm or cm to mm,but I prefer to convert mm to cm so 1cm is equals to 10mm so 12mm×10=120mm

Step-by-step explanation:

15cm:120cm

both are divisible by 15 so we will divide both by 15

15cm÷15:120cm÷15

1cm:8cm

Answer:

1/2 ÷ 4 = 8

Step-by-step explanation:

Dividing fractions is as easy as pie. Flip the second and multiply.

1/2 ÷ 4 = 1/8

A whole number secretly has a 1 underneath, like this: 4/1

Flip the second number over to get 1/4, then multiply straight across.

[tex]\frac{1}{2}[/tex] × [tex]\frac{1}{4}[/tex] = [tex]\frac{1}{8}[/tex]

Try to do the same for the other answers and see if they're right (they're not).

1/8 x 1/6 = 1/48

1/3 x 1/4 = 1/12

1/9 x 1/2 = 1/18

Explanation:

We can start with the relations ...

  [tex]\displaystyle\left(x+\frac{1}{x}\right)^3=\left(x^3+\frac{1}{x^3}\right)+3\left(x+\frac{1}{x}\right)\\\\\left(x+\frac{1}{x}\right)^5=\left(x^5+\frac{1}{x^5}\right)+5\left(x^3+\frac{1}{x^3}\right)+10\left(x+\frac{1}{x}\right)\\\\\textsf{From these, we can derive ...}\\\\x^5+\frac{1}{x^5}=\left(x+\frac{1}{x}\right)^5-5\left(\left(x+\frac{1}{x}\right)^3-3\left(x+\frac{1}{x}\right)\right)-10\left(x+\frac{1}{x}\right)[/tex]

  [tex]\displaystyle x^5+\frac{1}{x^5}=\left(x+\frac{1}{x}\right)^5-5\left(x+\frac{1}{x}\right)^3+5\left(x+\frac{1}{x}\right)\right)\\\\x^5+\frac{1}{x^5}=3^5 -5(3^3)+5(3)\\\\=((3^2-5)3^2+5)\cdot3=(4\cdot9+5)\cdot3=(41)(3)\\\\=\boxed{123}[/tex]

Answer:

75.5

Step-by-step explanation:

9,524 divided by 126 is equal to 75 with a remainder of 30.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

To perform the division of 9,524 by 126, you can use long division as follows:

 126 | 9,524 | 75

      882

      ---

      1124

     1008

     ----

      1164

     1134

     ----

        30

In other words:

9,524 ÷ 126 = 75 R 30

Therefore,

9,524 divided by 126 is equal to 75 with a remainder of 30.

Step-by-step explanation:

Answer:

3.05 or 31/2 pounds

56 ounces

Step-by-step explanation:

To find the total weight all the weights have to have the same units of measurements

It is either pounds is converted to ounces or ounces is converted to pounds

1. convert ounces to pound

1 ounce = 0.0625

12 ounces = 0.0625 x 12 = 0.75 pounds or 3/4

add together = 1 1/2 + 3/4 + 1 1/4 = [tex]1\frac{1}{2} + \frac{3}{4} + 1\frac{1}{4}[/tex]

[tex]2\frac{2 +3 + 1}{4}[/tex] = [tex]2\frac{6}{4}[/tex] = 3 1/2

2. 16 ounces = 1 pound

flour = 16 x 1 1/2 = 24

sugar = 16 x 1 1/4 = 20

total = 24 + 20 + 12 = 56 ounces
