Answer:

There are 1/7 cookies in the cookie jar. I give 4 to my friends. How many are left?

Step-by-step explanation:

For this case, we have by definition that, the median of a set of numbers is the average number in the set, after the numbers have been ordered from lowest to highest. If there is an even number in the set, the median is the average of the two middle numbers.

So, the given set is:

{4,5,5,6,10,11,12,13}

Since there are 8 numbers, the set is even. Then we find the average of the two numbers in the middle:

[tex]\frac {6 + 10} {2} = \frac {16} {2} = 8[/tex]

The median is 8

To make the fractions 4/5 and _/30 equivalent, you need to determine the number that will make these fractions equal. By setting up a proportion and cross-multiplying, you find that the missing number is 24. Thus 4/5 is equivalent to 24/30.

The equation you are tasked to solve is 4/5 = _/30. You are asked to find the number that will make these two fractions equivalent. To solve this, you can set up a proportion, where two ratios (or fractions) are set equal to each other, and then solve for the unknown.

You have the fractions 4/5 and _/30. Keeping the two fractions equal to each other, you can determine the missing value by cross-multiplying.

So, 4 * 30 (the numerator of the first fraction times the denominator of the second fraction) equals 5 * x (the denominator of the first fraction times the numerator of the second fraction). This gives you: 120 = 5x. Solving for x, divide 120 by 5, which equals 24.

Therefore, the fraction 4/5 is equivalent to 24/30.

Answer:

D

Step-by-step explanation:

First Rhonda makes a 20% down payment.  20% of $85 is:

0.20 × $85 = $17

So what's left is:

$85 - $17 = $68

So the number of monthly payments at $8 per month is:

$68 / 8 = 8.5

Rounding up, it will take 9 months to make all the payments.  If her father's birthday is on the third Sunday of June, she needs to make her ninth and final payment on June 1.  So her first monthly payment needs to be 8 months before that, or October 1.

[tex]g(x) = (4 {x)}^{2} [/tex]

EXPLANATION

We were given that,

[tex]f(x) = {x}^{2} [/tex]

Let

[tex]g(x) = a \times f(x)[/tex]

Or

[tex]g(x) = a {x}^{2} [/tex]

The point (1,16) is on the graph of g(x), hence it must satisfy its equation:

This implies that,

[tex]a {(1)}^{2} = 16[/tex]

[tex]a = 16[/tex]

We substitute the value of 'a' to get,

[tex]g(x) = 16 {x}^{2} [/tex]

Or

[tex]g(x) = (4 {x)}^{2} [/tex]

The correct choice is B.

Step-by-step explanation:

Here is a table.

To complete the table of values for the equation y = 3 - 2x, we substitute different x values into the equation to get the corresponding y values. Thus, values for y will depend on the chosen x values.

The equation given is y = 3 - 2x. To complete the table of values for this equation, you need to substitute different values of x into the equation and solve it to get the corresponding y-values. For example, if x = 0, then y = 3 - 2(0) = 3. Following this process, you can generate a large number of points that satisfy the equation and represent these as a table of x and y values.

Answer:

90% increase.

Step-by-step explanation:

Percent change in altitude = (difference in altitude * 100) / original altitude

= (95-50) * 100 / 50

= 90%.

Answer:

Percent of change in altitude = 90 %

Since the altitude increases from 50 ft to 95 ft the change is positive.

Step-by-step explanation:

Initial altitude, = 50 ft

Final altitude, = 95 ft

Increase in altitude = 95 - 50 = 45 ft

Percentage increase

              [tex]=\frac{45}{50}\times 100=90\%[/tex]

Percent of change in altitude = 90 %

Since the altitude increases from 50 ft to 95 ft the change is positive.

The center of a regular polygon is the center of an inscribed and a circumscribed circle.

The center of a regular polygon is the center of the circumscribed circle, which touches all the vertices of the polygon equally.

The center of a regular polygon is considered the center of the circumscribed circle. This is the circle that touches all the vertices (corners) of the polygon. When dealing with a regular polygon, which has all sides and angles equal, the center of this polygon is also the center of the circle that encloses it. This special circle is known as the circumscribed circle or circumcircle. The center is equidistant to all vertices of the polygon. The centroid of a polygon, which is the geometric center where all the corner points balance evenly, is analogous to the center of the circumscribed circle in regular polygons.

The given trigonometric equation is:

[tex] { \tan}^{2} x + 1 = { \sec}^{2} x[/tex]

We take the LHS and simplify to arrive at the RHS.

[tex]{ \tan}^{2} x + 1 = \frac{{ \sin}^{2} x}{{ \cos}^{2} x} + 1[/tex]

Collect LCM on the right hand side to get;

[tex]{ \tan}^{2} x + 1 = \frac{{ \sin}^{2} x + {\cos}^{2} x}{{ \cos}^{2} x} [/tex]

This implies that

[tex]{ \tan}^{2} x + 1 = \frac{1}{{ \cos}^{2} x} .[/tex]

[tex]{ \tan}^{2} x + 1 = {( \frac{1}{ \cos(x) }) }^{2} [/tex]

[tex]{ \tan}^{2} x + 1 = { \sec}^{2} x[/tex]

This identity has been verified .Therefore the correct answer is true.

Final answer:

The equation tan²(x) + 1 = sec²(x) is true and is derived from the fundamental Pythagorean trigonometric identity.

Explanation:

The statement tan²(x) + 1 = sec²(x) is true. This is based on a well-known trigonometric identity from mathematics.

In trigonometry, the Pythagorean identity for tangent and secant states that:

tan²(x) + 1 = sec²(x)

Which comes from the primary Pythagorean identity:

sin²(x) + cos²(x) = 1

by dividing each term by cos²(x) and recognizing that:

tan(x) = sin(x)/cos(x) and sec(x) = 1/cos(x).

Find the value of the missing angle for the following oblique triangle.

C = 58.1°

The value of missing angle C for the Oblique triangle is [tex]58.1^{0}[/tex]

In given oblique triangle, angle A is [tex]67.7^0[/tex] and angle B is [tex]54.2^0[/tex].

What is Oblique triangle?

An oblique triangle is any triangle that is not a right triangle. It could be an acute triangle (all three angles of the triangle are less than right angles) or it could be an obtuse triangle (one of the three angles is greater than a right angle).

As we know that, Sum of all angles of a triangle is [tex]180^0[/tex].

A + B + C =[tex]180^0[/tex]

[tex]67.7^0 + 54.2^0 + C = 180^0[/tex]

[tex]C = 180^0 - 121.9^0[/tex]

[tex]C = 58.1^0[/tex]

The problem evaluates the expression 47 + 2d, by substituting d = 3. This results in 47 + 2*3, which simplifies to 47 + 6. The final answer is 53.

This is a simple algebraic problem. The expression you're asked to evaluate is

and you've been told to substitute

d = 3

. So substituting, we get 47 + 2*(3). The multiplication operation takes precedence according to the order of operations, so next we calculate 2*3 to get 6. Adding this to 47 gives us 53. Therefore, the solution to 47 + 2d, for d = 3, is 53.
