Answers

Answer:

The answer is -10/77 .

Step-by-step explanation:

In order to find the value of xy/z, you have to substitute the value of x, y and z into the expression :

[tex] \frac{xy}{z} = xy \div z[/tex]

[tex]( \frac{2}{3} \times \frac{5}{7}) \div - \frac{11}{3} [/tex]

[tex] = \frac{10}{21} \times - \frac{3}{11} [/tex]

What is the distance between points A and B on the grid? (the grid is shown in the image). A. 3 units B. 4.5 units C. 5 units D. 5.5 units

Answers

Answer: C. 5 units

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

Explanation:

Since the x coordinates are the same, we can subtract the y coordinates to get

1.5 - (-3.5) = 1.5 + 3.5 = 5

Note how subtracting a negative is the same as adding.

-------

We can subtract in the other order

-3.5 - 1.5 = -5

but we need to make this result positive. A negative distance is not allowed. Absolute value is applied to make the result positive

|-5| = 5

The answer is 5 since both have 1.5 you don’t do anything with that you add the 3.5 and 1.5

In triangle PQR, m∠P = 83°, PQ = 7.6, and PR = 8.6. What is m∠R to the nearest degree? A. 45° B. 55° C. 35° D. 41°

Answers

Answer:

The unknown measurement of angle R to the nearest degree is 41°

Step-by-step explanation:

As you can see, we made a diagram form the given information in the problem. We are trying to find the measurement of angle R which is our unknown angle represented by the question mark.

in order to solve this problem, we are going to be using tangent. Tangent uses the opposite side and the adjacent side from the given or from the unknown angle measurement.

So, our equation will look like this.

[tex]tanx=\frac{7.6}{8.6}[/tex]

Since, we do not know the measurement of the unknown angle, then are going to use the inverse of tangent.

[tex]x=\frac{7.6}{8.6}(tan^-^1)[/tex]

Now, we solve. You can use a calculator to do these calculations.

The unknown measurement of the unknown angle to the nearest degree is 41° which is answer choice D.

These cones are similar. Find the volume
of the smaller cone. Round to the
nearest tenth.

Answers

Answer:

19.5

Step-by-step explanation:

The Volume of a cone is h/3(r²)[tex]\pi[/tex]

That means, for the larger cone,

66=h/3(3²)([tex]\pi[/tex])

66=h/3*9[tex]\pi[/tex]

66/9[tex]\pi[/tex]*3=h

h=7, so the height of the larger cone is seven

Since the cones are similar, it has to have the same ratio. 7/3 of 2 is 4.6666.  So the height of the smaller cone is 4.66666.

Putting that in the formula,

V=(4.66666/3)(2²)[tex]\pi[/tex]

V=1.555555*4*[tex]\pi[/tex]

V=19.547

Find RS. A. 5 B. 10 C. 9 D. 12

Answers

Answer:

RS = 5

Step-by-step explanation:

To find x use the equation 2x - 6 + 1 + x - 4 = 18

When you solve this x should equal 9

To find RS plug in x in (x-4)

9 - 4 (5)

Answer:

5 (Answer A)

Step-by-step explanation:

From the diagram we know that 2x - 6 + 1 + x - 4  must equal  18.

Then 2x - 6 + 1 + x - 4 = 18.  Combining like terms, we get:

3x - 5 - 4 = 18, or 3x - 9 = 18

Then 3x = 27, and so x must be 9.

Then the length of RS is 9 - 4 = 5 (Answer A)

Guys pls help me in this coz im very confused in this

Answers

Answer:

Step-by-step explanation:

1. Copy the diagram using ruler for parallel lines * ensure they (the parallel lines) each have the same distance each point to one another before drawing or adding the transversal line L(3)

The transversal doesn't have to be exact to the diagram but the parallel lines do have to be correct to prove that angle 1 + 5 are identical and fit into each other.

2. They only become corresponding because of being on transversal to add to 180 degree. As you will see when you draw angle 1 on colored paper near the first blue/green circle and match with 5 below in the second blue/green circle.

3. The reason they want tracing paper afterwards of the same shape is so you can use alternatively to cover angle 5 in your book.  

You will see they do cover each other.

Additional

''When two lines are crossed by another line (which is called the Transversal), the angles in matching corners are called corresponding angles. ''

Should you enter search for the above statement it will show you an interactive tool you can use for regarding maths transversal.

Here you can compare parallel lines like l(1) and l(2) as even if they were not parallel they would still be corresponding angles. As you will see.

● BE = ED

● (2/3)x = x-10

Substract x from both sides

● (2/3)x -x = x-10 - x

● (2/3) x - x = -10

Multiply x by 3 then ubstracr it from 2x

● (2x-3x)/3 = -10

● -x/3 = -10

Multiply both sides by -3

● (-x/3)×(-3) = -10 ×(-3)

Which ordered pair is a solution of the equation? 2x+4y=6x−y

Answers

Answer:

Step-by-step explanation:

"Which ordered pair" implies that there were several answer choices for this problem.  It's important that you share such answer choices.

2x+4y=6x−y reduces to 5y = 8x, and so y = (8/5)x

If we choose x = 2, then y = (8/5)(2) = 16/5 is a solution of the given equation.  There are an infinite number of such solutions.  All lie on the line y = (8/5)x.

A bin contains seven red chips, nine green chips, three yellow chips, and six blue chips. Find each probability. drawing a yellow chip, replacing it, and choosing a blue chip.

Answers

We will use the Multiplication Rule of Probability to find the answer.

This rule states that to find the intersection of two events, multiply them together.

First find the probability of drawing a yellow chip. Do this by creating a fraction.

Probability of drawing a yellow chip:

3 <— 3 yellow chips

25 <— 25 total chips

Then find the probability of drawing a blue chip:

6 <— 6 blue chips

25 (still 25 as you put the yellow chip back in)

Now that we have the two probabilities multiply them together.

3/25 * 6/25 = 18/625 = about 2.8% chance

The probability of drawing a yellow chip, replacing it, and choosing a blue chip will be 18/625.

What is probability?

Its basic premise is that something will almost certainly happen. The percentage of favorable events to the total number of occurrences.

A bin contains seven red chips, nine green chips, three yellow chips, and six blue chips.

Then the total number of the event will be

Total event = 7 + 9 + 3 + 6

Total event = 25

The probability of getting a yellow chip will be

Favorable event = 3 {yellow chip}

Then the probability will be

P(Y) = 3 / 25

The probability of getting a blue chip will be

Favorable event = 6 {blue chip}

Then the probability will be

P(B) = 6 / 25

Then the probability of drawing a yellow chip, replacing it, and choosing a blue chip will be

P = P(Y) x P(B)

P = (3/25) x (6/25)

P = 18 / 625

The probability of drawing a yellow chip, replacing it, and choosing a blue chip will be 18/625.

Write an absolute value equation to satisfy the given solution set shown on a number line. PLEASE HELP

Answers

Answer: Ix - 4I ≤ 4

Step-by-step explanation:

You can see a black dot in the zero, and a black dot in the 8.

So those are the extremes of our set and are included in the set of solutions, we have that the set is defined by:

0 ≤ x ≤ 8.

Now we want to construct an absolute value equation such that the set {0 ≤ x ≤ 8} is the set of solutions.

The first step is to find the middle value of that set:

The middle value is equal to half of the difference between the extremes:

m = (8 - 0)/2 = 4.

Now we know the middle point, so we can write the equation:

Ix - mI ≤ m

m = 4

Ix - 4I ≤ 4

That is our inequality.

Where the "equal" part of ≤ is for the values x = 0 and x = 8.

Answers

Answer:

Step-by-step explanation:

First we need to define the formula for surface area

2(wl+hl+hw)=100

Now we can replace length with x

That makes width .5x and height x+3

2(.5x^2+x^2+3x+.5x^2+1.5x)=100

2(2x^2+4.5x)=100

2x^2+4.5x=50

2x^2+4.5x-50=0

Insert into quadratic equation (a=2x^2, b=4.5, c=-50)

x=4 or -6.25

x can't be negative so x is 4

Answer:

8

Step-by-step explanation:

Since this isosceles triangle has been broken down into two right triangles, and we already know that two sides are the exact same (note that there are 2 x's) that means BD and BC are going to be the exact same length. Since BD is 4, that means BC will be 4, and that means

[tex]4+4=8[/tex]

The answer is 8. Since BD is only 1/2 of the line and it equals 4. Since the other half of the line is the same length as BD the total would be 8 because 4•2=8.

p% = 750/1000

p% =75%

You paid 75%

The discount is 100 -75%

25 % discount

Answer:

Below

Step-by-step explanation:

First item)

The original price of the video games is 80$ wich is 100%

This item has a 20% discount.

Let x be the value of the dicount in dollars.

● 80 => 100

● x => 20

● x =(80×20)/100 = 16$

So the amount of the discount is 16$.

● 80-16 = 64 $

So the amount that was paid is 64$

■■■■■■■■■■■■■■■■■■■■■■■■■■

Second item):

The price that was paid is 11.2$out of 14$ initially.

Let x be the percentage of 11.2

● 14$ => 100%

● 11.2$ => x

● x = (11.2×100)/14 = 80%

● 100-80 = 20%

So the percentage of discount was 20%

■■■■■■■■■■■■■■■■■■■■■■■■

Third item):

The laptop was boughr for 750$ out of 1000$ initially

No need to do calculations here.

Notice that: 750/1000 = 3/4 = 0.75 = 75%

● 1000-750 = 250

So 250 is the amount discounted wich is 25% of 1000$

Answer:

The correct option is;

Left object volume = right object volume

Step-by-step explanation:

The shapes given in the question are two circular cones that have equal base radius and equal height

The formula for the volume, V of a circular cone = 1/3 × Base area × Height

The base area of the two shapes are for the left A = π·r², for the right A = π·r²

The heights are the same, therefore, the volume are;

For the left

[tex]V_{left}[/tex] = 1/3×π·r²×h

For the right

[tex]V_{right}[/tex] = 1/3×π·r²×h

Which shows that

1/3×π·r²×h  = 1/3×π·r²×h and [tex]V_{left}[/tex]  = [tex]V_{right}[/tex], therefore, the volumes are equal and the correct option is left object volume = right object volume.
