Answer:

Part A

x is 46°

Part B

Alternate angles are angles that are in relatively opposite locations relative to a transversal

Step-by-step explanation:

Part A

∠DRP  = 110° (Given)

∠QPA = 64° (Given)

∠QPR =

Given that AB is parallel to CD, we have;

∠DRP is congruent to ∠APR (Alternate angles to a transversal RP of parallel lines AB and CD)

Therefore, ∠APR = 115°

∠APR = ∠QPA + ∠QPR (Angle addition postulate)

∴ 115° = 64° +  ∠QPR

∠QPR = 110° - 64° = 46°

x = 46°

Part B.

Given that AB is parallel to CD, the lines common (that intersects) both lines are the transversal lines

The angles formed between the parallel lines and the transversal lines have special relationships based on their position with respect to each other

In the question, the angle 110° given between CD and the transversal RP, is found to at an alternate position to the angle ∠APR between the same transversal RP and AB and given that alternate angles are always equal, angle ∠APR is therefore also equal to 110°.

D. 27 party favors w/ 37 cents left

The number of favors Gianna and Moriah can buy is 27 favors with $0.37 left over. Option C is correct.

Given that,

Gianna had $4.75 and Moriah had $6.42. They put their money together to buy party favors that cost $0.40 each.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

here,

The total money Gianna and Moriah spend = 4.75 + 6.42 = $11.17

They put their money together to buy party favors that cost $0.40 each.

Number of favors bought = 11.17/ 0.40 = 27 + 0.37/0.40

Thus, the number of favors Gianna and Moriah can buy is 27 favors with $0.37 left over. Option C is correct.

system:

y+3x=180

y+5x=270

y=180-3x (and we put that instead of 'y' in the second equation)

(180-3x)+5x=270

180+2x=270

2x=90

x=45

so one book costs $45

and school bag:

y+3×45=180

y+135=180

y=180-135

y=45

Answer:

Each book costed 45$.

Step-by-step explanation:

Let x represent the price of a school bag and y represent the price of a book.

we get the following system of equations:

x+3y=180  (equation 1)

x+5y=270 (equation 2)

using equation 1: x=180-3y

then we substitute x in equation 2 in order to find y:

180-3y+5y=270

180+2y=270

2y=270-180=90

y=90/2=45

and we know that y represents the price of a book, so each book costs 45$.

Answer:

Step-by-step explanation:

#7- Irrational; The adding of one 8 every time it well, gets to an 8, changes the pattern. For a decimal to be rational, it has to be steady, set from the beginning, and has to keep that pattern the whole time.

#9- C and E;

C. Pi (3.14…) is a continuous number that goes on forever and has no pattern to it, thus making it irrational.

E. Is one of those decimals that just decide to be different and difficult and have no repetition of patterns and goes on forever

#10- Just the square root of 15; Square root of 196 is 14; 5/9 is 0.5repeating… which I beliiieeeeve is rational?; and 7.27repeating have the same ongoing pattern

#11- 26, -3/2, 0, 9;

26 is a whole number; -3/2 would be -1.5 as a decimal, no extra numbers; 0 just… well… 0, so rational; and 9 is a whole number.

Answer:

Step-by-step explanation:

Step 1 is to find the total number of balls in the pail.

There are 8 balls in total

Now that you know there are 8 balls, you have to find out how many of those 8 are green. This is because you want to pull out a green ball. You would do the same thing for any other colored ball.

Since 4 out of the 8 balls in the pail are green, you can write this as 4/8

The last step is to simplify to get 1/2 which in other terms is 50%.

So the probability of you pulling a green ball is 50%

Answer:

Sure, I'll explain the cosine rule and sine rule in simple terms:

The cosine rule (also known as the law of cosines) is used to find the length of a side or the measure of an angle in a triangle given the lengths of the other sides and the angle between those sides. It states that c^2 = a^2 + b^2 - 2ab cos(C), where c is the length of the side opposite angle C, and a and b are the lengths of the other two sides.

Here's an example of how to use the cosine

Suppose we have a triangle with sides a=6, b=8, and an angle between them c=45 degrees. We want to find the length of the remaining side of the triangle, side a.

Using the cosine rule:

a^2 = b^2 + c^2 - 2bc * cosA

where A is the angle opposite side a, we can plug in our values and solve for a:

a^2 = 8^2 + 6^2 - 2(8)(6) * cos(45)

a^2 = 64 + 36 - 96 * 0.707

a^2 = 10.56

a = sqrt(10.56)

a = 3.25 (rounded to two decimal places)

Therefore, the length of side a is approximately 3.25 units.

Answer:

x < 3

Step-by-step explanation:

−2(5−4x)<6x−4

Use the distributive property to multiply −2 by 5−4x.

−10+8x<6x−4

Subtract 6x from both sides.

−10+8x−6x<−4

Combine 8x and −6x to get 2x.

−10+2x<−4

Add 10 to both sides.

2x<−4+10

Add −4 and 10 to get 6.

2x<6

Divide both sides by 2. Since 2 is >0, the inequality direction remains the same.

x= 6/2

Divide 6 by 2 to get 3.

x= 3

Answer:

r=4-2\sqrt{2}

Step-by-step explanation:

Let's set up an equation! (most cringe phrase ever, but hey, it works)

Because this is a square, we can do something like this: \(\frac{r}{\sqrt{2}}\)+r=2

If we multiply all sides by \(\sqrt{2}\), then we get \(r+r\sqrt{2} = 2\sqrt{2}\)

Time to solve it! (you could've gotten here another way, tho)

\(r(1+\sqrt{2} )=2\sqrt{2}\)

\(r=\frac{2\sqrt{2} }{1+\sqrt{2} }\)

Rationalizing the denominator, we get \(r=4-2\sqrt{2}\)

Answer:

47.5% of students fall within heights of 100 cm to 120 cm

Step-by-step explanation:

We are given that heights of Grade 1 students are normally distributed

Mean = \(\mu = 100 cm\)

Standard deviation = \(\sigma = 10 cm\)

a)

Empirical rule

68% of data lies within the first standard deviation from the mean i.e\(.(\mu-\sigma , \mu+\sigma)=(100-10,100+10)=(90,110)\)

95% of all the data will fall within two standard deviations  i.e.\((\mu-2\sigma , \mu+2\sigma)=(100-2(10),100+2(10))=(80,120)\)

99.7% of data lies within the three standard deviations i.e.\(( \mu - 3 \sigma , \mu +3 \sigma)=(100-3(10),100+3(10))=(70,130)\)

b)Percentage of students fall within heights of 100 cm to 120 cm

Using the normal distribution curve

Percentage of students fall within heights of 100 cm to 120 cm = \(\frac{1}{2} \times 95\% = 47.5\%\)

Hence 47.5% of students fall within heights of 100 cm to 120 cm

Option (C) 484 ft²

The Five Sided figure can be divided into 2 Triangles and 1 Rectangle.

Length of the triangle = 22 Feet

Breadth of the triangle = 8 Feet

Area of the triangle = (Length * Breadth) / 2

                                 = (22 * 8) / 2

                                 = 176/2

                                 = 88 ft²

Length of the triangle = 22 Feet

Breadth of the triangle = 4 Feet

Area of the triangle = (Length * Breadth) / 2

                                 = (22 * 4) / 2

                                 = 88/2

                                 = 44 ft²

Length of the rectangle = 22 Feet

Breadth of the rectangle = 16 Feet

Area of the triangle = (Length * Breadth)

                                 = (22 * 16)

                                 = 352 ft²

The Total Area of the Five Sided figure can be found by summing up the areas of the Triangles and the Rectangle.

The Total Area of the figure is 88 + 44 + 352 = 484 ft²

So, the total area of the figure is 484 ft².

The area of the trapezoid is 308 ft2, the correct option is D.

We are given that;

Shorter side= 16 feet

b2​=6+6=12 ft

Height= 22 feet

Now,

To find the area of a trapezoid, you need to know the lengths of the two parallel sides (the bases) and the height. The formula for the area of a trapezoid is:

A=21​(b1​+b2​)h

where b1​ and b2​ are the lengths of the bases and h is the height1.

Substitute these values into the formula and simplify:

A=21​(16+12)×22

A=21​×28×22

A=14×22

A=352

Therefore, by the area the answer will be 308 ft2.
