Answer 1

Answer:

1. 5/40

2. 3/20

4. 0

Step-by-step explanation:

1. 5/40

There are 5 pairs of 6 inch pliers out of a basket with 40 pliers in the basket. So there is only a 2% chance one of those pliers would get chosen so its impossible to happen.

2. 3/20

There are 3 large hammers in the basket which has 20 hammers in it. So there is only a 15% chance so its not likely to happen.

3. I don't really know about this one

4. 0%

There are no 6 inch pliers in the second basket whish only has 20 hammers in it so it is impossible to pick one out because there's a 0% chance of it happening

The surface area of a cube is 96 square inches. What is the length of an edge of the cube, in inches?
plz help, 7th grade math

Answers

Answer:

16 inches

Step-by-step explanation:

A cube has 6 sides and to find the surface area you would multiply one side by 6, or add the six sides together. So instead, to find the length of one side, you divide the surface area, 96, by 6 to get 16.

Hope this helps you :)

Answer:

Step-by-step explanation:

let x be the length of cube=x in

surface area=6 x²

6 x²=96

x²=96/6=16

x=√16=4 in

The equivalent expression to 3(x+ 1) is (3x+3).

What is Expression?

An expression is a grouping of terms that have been joined together using mathematical operations such as subtraction, addition, multiplication, and division. In mathematics, the terms involved in an expression are:

A constant is an unchanging numerical value.Variable: A variable is a symbol with no fixed value.A term might be a single constant, a single variable, or a combination of a variable and a constant multiplied or divided.A coefficient is a number in an equation that is multiplied by a variable.

We have the Expression 3(x+1)

Now, using the Distributive Property

a x ( b + c) = a x b + a x c

So, 3(x+1)

= 3(x) + 3(1)

= 3x+ 3

So, the equivalent expression is (3x+3).

Find the perimeter and the area of the polygon with the given vertices.

A (12,2), B (12,13), C (15,13), D (15,2)
The perimeter is __ units.

The area is __ square units.

Answers

Answer:

Step-by-step explanation:

As points A and B have same x-coordinate, length of AB will be given by the difference of y-coordinate

AB = 13 - 2 = 11 units

As points C and D have same x-coordinate, length of CD will be given by the difference of y-coordinate

CD = 13 - 2 = 11 units

As points B and C have same y-coordinate, length of BC will be given by the difference of x-coordinate

BC = 15 - 12 = 3 units

As points A and D have same y-coordinate, length of AD will be given by the difference of x-coordinate

AD = 15- 12 = 3 units

AB = CD = 11 units

BC = AD = 3 units

So,ABCD is a rectangle

Area = 11 * 3 = 33 square units

Perimeter = 11+11+3+3 = 28 units

Answer:

Solution :-

At first

Length of AB = 13 - 2 = 11 cm

Length of CD = 13 - 2 = 11 cm

Length of BC = 15 - 12 = 3 cm

Length of AD = 15 - 12 = 3 cm

Now

Perimeter = 11 + 11 + 3 + 3

Perimeter = 22 + 6

Perimeter = 28

Area = 11 × 33 = 33 cm

Tell whether the angles are complementary or supplementary. Then find the value of x.

Answers

supplementary and x=13

8x+2+74=180
8x+76=180
180-76= 104
8x=104
104/8=13
x=13

The answer is that it’s supplementary and that x=13

You now know a lot about all the angles formed from two straight lines that intersect. You know which angles are congruent and which angles are supplementary. Based on this information, you can find the angle measurements of all the angles even when you only know the measurement of one angle. In the figure below, angle 2 measures 145 degrees. What are the measurements of angles 1, 3 and 4? A angle 1 = 35 degrees, angle 3 = 145 degrees, angle 4 = 35 degrees B angle 1 = 30 degrees, angle 3 = 30 degrees, angle 4 = 160 degrees C angle 1 = 35 degrees, angle 3 = 35 degrees, angle 4 = 145 degrees D angle 1 = 135 degrees, angle 3 = 145 degrees, angle 4 = 35 degrees

Answers

Answer:

This is the correct way to set up the equation:

9x + 88 + 6x + 182 = 180

I'm going to move some things around so we can combine like terms. It now reads:

9x + 6x + 88 + 182 = 180

9x + 6x = 15x, so the equation now reads:

15x + 88 + 182 = 180

88 + 182 = 270, so the equation reads:

15x + 270 = 180

Subtract the 270 from both sides. 180 - 270 is -90:

15x = -90

Divide both sides by 15. -90 divided by 15 = -6:

x = -6

Now we can substitute -6 back into the separate equations.

9(-6) + 88 = ?

9 times -6 is -54. -54 + 88 = 34.

6(-6) + 182 = ?

6 times -6 = -36. -36 + 182 = 146

Now we can add 34 and 146 together.

34 + 146 = 180

Find the value of x - this is circle segments.

Answers

Given:

Diagram of a circle and its two secant from an exterior point.

To find:

The value of x.

Solution:

We know that, If two secant are on a circle from an exterior point, then the products of measure of secants and measure of external segments of secants are equal.

Using the above property, we get

[tex](x+7)x=(2+2)2[/tex]

[tex]x^2+7x=(4)2[/tex]

[tex]x^2+7x=8[/tex]

[tex]x^2+7x-8=0[/tex]

Splitting the middle term, we get

[tex]x^2+8x-x-8=0[/tex]

[tex]x(x+8)-1(x+8)=0[/tex]

[tex](x+8)(x-1)=0[/tex]

Using zero product property, we get

[tex](x+8)=0[/tex] and [tex](x-1)=0[/tex]

[tex]x=-8[/tex] and [tex]x=1[/tex]

Side cannot be negative.

Therefore, the only possible value of x is 1.
