The two angles with the variable x form a linear pair and therefore:

Angles 16x - 18 and 12y are congruent as vertical angles:

Answer:

x = 7.5

y = 8.5

Step-by-step explanation:

Linear Pair

Two adjacent angles that sum to 180° (two angles which when combined together form a straight line).

To find x, equate the sum of the two angles with the variable x to 180° and solve:

⇒ (16x - 18)° + (10x + 3)° = 180°

⇒ 16x - 18 + 10x + 3 = 180

⇒ 26x - 15 = 180

⇒ 26x = 195

⇒ x = 7.5

Vertical Angles Theorem

When two straight lines intersect, the opposite vertical angles are congruent.

Therefore:

⇒ (16x - 18)° = 12y°

Substitute the found value of x into the equation and solve for y:

⇒ 16x - 18 = 12y

⇒ 16(7.5) - 18 = 12y

⇒ 120 - 18 = 12y

⇒ 102 = 12y

⇒ y = 8.5

Answer:

64x4=(256) +13=269

Step-by-Step:

If 64 skittles are in each bowl that means there is 4 bowls filled with 64 skittles so you multiply 4 and 64. After that you add how many skittles Evan ate to find the amount of skittles in the bag originally. So 256+13

Answer:

243

Step-by-step explanation:

since there are 64 skittles in one bowl and there are 4 bowls you have to multiply 64 by 4=256

And he ate 13 so you have to subtract 256 from 256 which gives you 243.

equation= (64 x 4) - 13

Answer:

The monthly cost is 30+0.05n if we call the number of texts n. Heather wants to keep this less than 60, so the inequality is: 30+0.05n < 60

Step-by-step explanation:

Note that we can also subtract

30 from each side: 0.05n<30 We can also divide both sides by 0.05 n < 600

This is the most useful inequality, since it tells Heather she needs to send fewer than 600 texts per month, or about 20 per day.

To estimate the volume using the Midpoint Rule with \(\displaystyle n=5\), we need to divide the interval \(\displaystyle 0\leq x\leq 1\) into \(\displaystyle n\) subintervals of equal width. Since \(\displaystyle n=5\), each subinterval will have a width of \(\displaystyle \Delta x=\frac{1-0}{5}=\frac{1}{5}\).

Now, let's calculate the volume using the Midpoint Rule. The formula for the volume obtained by rotating about the y-axis is:

\(\displaystyle V\approx 2\pi \sum _{i=1}^{n}y_{i}\Delta x\)

where \(\displaystyle y_{i}\) represents the value of the function \(\displaystyle y=\sqrt{1+x^{3}}\) evaluated at the midpoint of each subinterval.

First, let's find the midpoints of the subintervals. Since the width of each subinterval is \(\displaystyle \Delta x=\frac{1}{5}\), the midpoint of the \(\displaystyle i\)-th subinterval is given by:

\(\displaystyle x_{i}=\frac{\Delta x}{2}+\left( i-\frac{1}{2}\right) \Delta x=\frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\)

Substituting \(\displaystyle x_{i}\) into the function \(\displaystyle y=\sqrt{1+x^{3}}\), we obtain:

\(\displaystyle y_{i}=\sqrt{1+\left( \frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\right) ^{3}}\)

Now, we can calculate the approximate volume using the Midpoint Rule:

\(\displaystyle V\approx 2\pi \sum _{i=1}^{5}y_{i}\Delta x\)

Substituting the values of \(\displaystyle y_{i}\) and \(\displaystyle \Delta x\) into the formula, we can evaluate the sum and compute the estimated volume.

Answer:

Based on the information given, we can estimate the number of students who own exactly two internet-compatible devices as follows:

If Brianna surveyed a random sample of 150 students out of a total of 480 students in her school, we could assume that the sample is representative of the population. Let p be the proportion of students in the population who own exactly two internet-compatible devices.

We can estimate p by calculating the proportion of students in the sample who own exactly two internet-compatible devices. Let x be the number of students in the sample who own exactly two internet-compatible devices. Then we have:

p ≈ x/150

We can use this estimate of p to estimate the number of students in the population who own exactly two internet-compatible devices. Let N be the total number of students in the population who own exactly two internet-compatible devices. Then we have:

N ≈ p * 480

Substituting the estimate of p, we get:

N ≈ (x/150) * 480

Simplifying, we get:

N ≈ 3.2x

Therefore, we can estimate that approximately 3.2 times the number of students in the sample who own exactly two internet-compatible devices also own exactly two internet-compatible devices in the population. If, for example, the sample proportion is 0.2 (or 20%), then we can estimate that approximately 3.2 * 0.2 * 480 = 153.6 students in the population own exactly two internet-compatible devices.

Answer: 20 - 2d

Step-by-step explanation:

Since Mark bought 2 drinks and a drink cost d dollars the drinks are represented by 2d.

he brought $20 in all to the game so you would have to subtract how much the drinks cost from the total amount of money he bought to the game.

So you would get the expression 20 - 2d = m

Where m represents the money that he has after the game.

Answer:

alright so every person shook 7 people's hands so 7x and there are 7 people so 7(7) and that is 49

There are 21 handshakes happened.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

There are 7 people meet each other and each shake hands only once with each of the others.

Now,

We know that;

Number of handshakes = n (n - 1) / 2

Here, Number of people = 7

So, we can formulate;

Number of handshakes = n (n - 1) / 2

                                     = 7 (7 - 1) / 2

                                     = 7 × 6 / 2

                                     = 7 × 3

                                     = 21

Thus, There are 21 handshakes happened.

THIS MIGHT NOT BE WHAT YOU ARE LOOKING FOR AND MIGHT NOT BE CORRECT! READ FIRST!

The answer is A. The slope of the line is rise/run = 4/2 = 2.1. This means that each kilometer costs $2.10. The y-intercept is 2.1, which means that the initial fee is $2.10. So the correct statement is: The slope is 2.1. This means that each kilometer costs $2.10.

The other statements are incorrect. The slope is not 5, so each kilometer does not cost $5. The y-intercept is not 5, so the ride does not last 5 kilometers. The y-intercept is the value of the function when the input is 0, which in this case is the initial fee of $2.10.

Step-by-step explanation:

1. Approach

This problem asks one to find the surface area of the given figure. This can be done by splitting the given figure into two similar figures. Then calculate the surface area of each of the similar figures. After doing so, subtract the covered surface areas, the contact point between the two simple figures is not a part of the surface area since it is covered by the other part of the figure. Remember to take away twice the area of this contact point, since it is present on both figures.

2.Find the surface area of the first figure

The surface area of a figure is the two-dimensional space around the figure. In essence, if one were to wrap the figure in paper, the surface area is the amount of paper one would need. Find the 2-dimensional area of each side, this can be done by multiplying all combinations of two dimensions together, adding the results, and then multiplying that value by (2).

(5) * (10) = (50)

(5) * (7) = (35)

(7) * (10) = (70)

Now add thee value together,

(50) + (35) + (70)

= (155)

Double the result,

(155) * (2) = (310)

3. Find the surface area of the other figure

Now repeat the process that was used to find the surface area of the other figure for this figure.

(8) * (4) = (32)

(4) * (3) = (12)

(8) * (3) = (24)

Add the results,

(32) + (12) + (24) = (68)

Double the value,

(68) * (2) = (136)

3. Now subtract the repeated side

Now that one has the value of both simple figures, add up the value and then subtract twice the value of the repeated side.

(310) + (136) = (446)

(446) - ((2)*(4)*(3))

= (446) - (24)

= (422)

First, we need to find how many liters of horchata Ana has in her refrigerator:

7/10 of a liter is the same as (7/10) / (1/1) = 7/10 liters.

To find how many glasses of horchata she can pour, we divide the total amount of horchata by the amount in each glass:

(7/10) ÷ (1/8) = (7/10) x (8/1) = 56/10 = 5.6

Ana can pour 5.6 glasses of horchata. Since she cannot pour a fraction of a glass, she can pour a maximum of 5 glasses of horchata.

Step-by-step explanation:

To subtract 7/12 from 3 1/8, we need to convert the mixed number 3 1/8 to an improper fraction first:

3 1/8 = (3 × 8 + 1) / 8 = 25 / 8

Now we can subtract 7/12 from 25/8:

25/8 - 7/12 = (25 × 3) / (8 × 3) - (7 × 2) / (12 × 2) = 75/24 - 14/24

= (75 - 14) / 24 = 61/24

So, 3 1/8 - 7/12 = 61/24 in simplest form.

Answer: 18x-12

Step-by-step explanation:

18x-12

The perimeter of the shown rectangle is given by the equation:

P = 2*(6x + 2)*(3x - 8)

For a rectangle of length L and width W, the perimeter is:

P = 2*(L + W).

Here we have:

L = 6x + 2

W = 3x - 8

Replacing that in our equation, we get:

P = 2*(6x + 2)*(3x - 8)

So the perimeter is given by the above quadratic equation.
