pleaseeee help thanks.. lol

Answer:

<7 = 47, 2x - 5 + 47 = 180, x = 69

Step-by-step explanation:

<5 and <7 are vertical angles, which means that they have the same degree.

<7 + <6 = 180. <6 = 2x - 5. 2x - 5 + 47 = 180.

Solve

2x - 5 + 47 = 180

2x + 42 = 180

2x = 138

x = 69

Answer:

(-1, 8)

Step-by-step explanation:

Make y the subject:

x + y = 7 ⟹ y = -x + 7

1. Substitute the value for y into 7x + y = 1 and solve for x:

7x + (-x + 7) = 1

7x - x + 7 = 1

6x + 7 = 1

6x + 7 - 7 = 1 - 7

6x = -6

6x ÷ 6 = -6 ÷ 6

x = -1

2. Substitute the given value of x into x + y = 7 and solve for y:

x + y = 7

-1 + y = 7

-1 + 1 + y = 7 + 1

y = 8

Therefore, the solution to this system of equations is: (-1, 8).

Answer: x= 385/12

Step-by-step explanation:

You would first change the denominator to some number that is common. Then combine the like terms. Lastly, subtract the fraction from the equal and you get your x.

[tex]\frac{13}{4} +\frac{1}{6} +x=\frac{71}{2} \\(\frac{39}{12})+(\frac{2}{12})+x=\frac{426}{12} \\\frac{41}{12}+x=\frac{426}{12} \\x=\frac{385}{12}[/tex]

Answer:

35.28 cm³

Explanation:

Volume of triangular prism = Area of Base × Length

Find area of base of the triangle:

1/2 × base × height = 1/2 × 4.2 × 2.8 = 5.88 cm²

Then find volume:

A × L = 5.88 × 6 = 35.28 cm³

1/2 x 4.2 =2.1

2.8 x 6 x 2.1 =

35.28

Answer:

2.25 cm³

Step-by-step explanation:

The volume of a pyramid can be found using the formula:

[tex] \boxed{\text{volume of pyramid= ⅓×base ×height}}[/tex]

Base area

= area of square

= side ×side

= 1.5²

= 2.25 cm²

Volume of paperweight

= ⅓(2.25)(3)

= 2.25 cm³

Answer:

Option c) 72 cm²

Step-by-step explanation:

In the figure attached we can see a rectangle ABCD with length 12 cm and width 9 cm.

A  triangle PEF with height BE and base EF.

Since side AE = 3 cm, so side EB = EC = 9 - 3 = 6cm

and EF = AD = 12 cm

Now we will find the area of of the parts of the card that are not shaded.

Area of parts that are not shaded = Area of rectangle - area of shaded triangle

= (12×9) - 1/2 (BE)(EF)

= 108 - 1/2(6)(12) = 108 - (3)(12) = 72

Option c) 72 cm² is the area of non shaded part.

Answer:

3) 1/6

4) 1/2

5) 1/2

6) 1/3

7) 1/2

8) 1/3

9) 0

10) 1

11) 5/6

12) 1/3

Step-by-step explanation:

3) There is only one 2 on a die. Thus, the probability would be 1/6.

4) There are 3 even numbers on a die (2, 4, 6). Thus, the probability would be 3/6 which simplifies down to 1/2.

5) There are also 3 odd numbers on a die (1, 3, 5). Thus, the probability would be 3/6, which again simplifies down to 1/2.

6) There are only 2 numbers greater than 4 on a die (5, 6). This makes the probability 2/6, which simplifies to 1/3.

7) There are 3 numbers less than 4 on a die (1, 2, 3). This makes the probability 1/2.

8) The probability of getting a 6 or 2 is 1/3. This is because when the probability statement says "or" you add the probabilities of the individual events to get the probability. In this case it would be 1/6 + 1/6 which equals 2/6, simplified to 1/3.

9) The probability of rolling a 7 is 0. There is no 7 on the die, so you would not be able to roll a 7.

10) All the numbers on a die are less than 10, this makes the probability 1.

11) There are 5 other numbers that aren't "5" on the die, this makes the probability 5/6.

12) Composite numbers are a number that can be formed by multiply 2 smaller numbers together. There are only 2 on a die, 4 and 6. Four is a composite number because 2*2 = 4. Six is a composite number because 3*2 = 6. Therefore, the probability will be 1/3 (2/6).

An easy way to answer this question is:

Step-by-step explanation:

Add all the men together and then divide them by their number which in this case is 10.

Do the same thing to women add them all together and then divide them by their number which in this case is 11.

BTW I am doing a 100 point question come if you want points. The question is easy

Answer:

Men is 22.1

Women is 18

Step-by-step explanation:

You should add the numbers of the men and women separately, then divide each by the amount of numbers available.

In this case, you add the digits in Men, equaling 221, then divide them by 10, which will equal 22.1.

Let’s solve for Women, add the digits of women together, you’ll get 198, divide that number by 11, your answer would be 18.

Step-by-step explanation:

<YOZ = 60°

When two lines intersect each other, then four angles are formed. The angles that are opposite to each other at the intersection point are known as vertically opposite angles. VERTICALLY OPPOSITE ANGLES ARE ALWAYS EQUAL.

If < VOX = 90⁰, then <VOW = 60⁰.

<VOW and <YOZ are vertically opposite angles.

Answer:

Step-by-step explanation:

Givens

<VOX = 90 degrees

<WOX = 30 degrees

<YOZ  = ? degrees.

Solution

<VOW is the complement of <WOX

<VOW = <VOX - <WOX                         Substitute values

<VOW = 90 - 30                                     Subtract

<VOW = 60                              

<YOZ = <VOW                                        Property of vertically opposite <s      

<YOZ = 60                                              Substitute value

Answer

<YOZ = 60 degrees

Answer:

Y and Z.

Step-by-step explanation:

My reasoning is that because scalene triangles have all different measurements, Y and Z would be correct since they have multiple different measurements. X is an obtuse triangle, while W is a right triangle, so that leaves Y and Z.

===========================================================

Explanation:

Triangle W is a right triangle because of the square marker. This angle is 90 degrees, also known as a right angle.

Acute triangles on the other hand must have all angles smaller than 90 degrees. This rules out triangle W.

The missing angle of triangle X is 180-40-35 = 105 degrees, showing this triangle is obtuse. Obtuse triangles have exactly one angle that is between 90 and 180. Therefore, we rule out triangle X as well.

Triangles Y and Z are acute because all angles are smaller than 90 degrees. For triangle Y, the missing angle is 180-70-80 = 30. For triangle Z, the missing angle is 180-65-45 = 70 degrees.

---------------

That takes care of the "acute" portion. Now onto the "scalene" part.

All four triangles shown are scalene. Why? Because all three sides are different lengths, as indicated by the different tickmarks.

However, we ruled out triangles W and X since they weren't acute.

Answer:

15 x 1.75 + 1.59

Step-by-step explanation:

Dalton spent $26.25 on the notebooks, along with $1.59 for one marker; adding up to a $27.84 total.

Answer:

$27.84

Step-by-step explanation:

Given :

⇒ 15 notebooks for $1.75 each

⇒ 1 marker for $1.59

==============================================================

Solving :

⇒ Total cost = 15 × 1.75 + 1.59

⇒ Total cost = 26.25 + 1.59

⇒ Total cost = $27.84

Answer:

205.2

Step-by-step explanation:

First get the area's of the 3 triangles on top of the base, the formula is base x height divided by 2

10 x 9 = 90

90 / 2 = 45

Multiply the area of the 3 sides together :

45 x 3 = 135

Now find the area of the base triangle :

9 x 7.8 = 70.2

To find the surface area of the ENTIRE shape you have to add all the sides :

135 + 70.2 = 205.2

Answer:

12 square units

Step-by-step explanation:

The answer might be a little easier to see if we slide that triangle on the left over to turn this shape into a rectangle! This is a technique you can apply to any parallelogram. Looking at the newly constructed rectangle, we can find its area by multiplying its length (2) and width (6) for an area of 2 · 6 = 12 square units.

Answer:

12 units squared

Step-by-step explanation:

Formula for area of a parallelogram:

A = b • h

The base of the parallelogram is 6 units. The height of the parallelogram is 2 units. Multiply the two numbers together. 6 • 2 = 12 units squared.
