Select ALL the values that make the inequality true: n < -15

Answer:

Step-by-step explanation:

We know he earns $14 per child under 12

So he'll earn 22 times 14 which is $308 earned.

46% of 308 is basically 0.46 X 308=$141.68 spent on props.

He profits $166.32

If only 10 children attend.

He earns 10 times 14= $140

46% of these earnings is for props and 54% is profit so

0.54 X 140=$75.60.

Thus he profits $75.60 if 10 children attended.

The profit will amount to $75.60 when only 10 children under the age of 12 attend the party.

The percentage is defined as a ratio expressed as a fraction of 100.

We are aware that he receives $14 for each child under the age of 12.

Thus, he will make $308 after multiplying 22 by 14.

In other words, 46% of 308 is 0.46 × 308 or $141.68 spent on props.

He earns $166.32.

If just 10 kids show up.

He makes $10 multiplied by 14 for a total of $140.

Props account for 46% of these revenues, while profits make up 54%, therefore

0.54 × 140=$75.60.

So, if 10 kids showed up, he makes $75.60.

Thus, the profit will amount to $75.60 when only 10 children under the age of 12 attend the party.

Step-by-step explanation:

Graph Solution to System of Equations

One approach to solving systems of equations of two variables is the graph method.

Both equations are plotted in the same grid and we find the intersection point(s) of both graphs. Those are the feasible solutions.

The annual premium p as a function of the client's age a for two companies are given as:

Company A: p= 2a+24

Company B: p= 2.25a+13

The graphs of both functions are shown in the image below.

The red line indicates the formula for Company A and the blue line indicates the formula for Company B.

It can be seen that both lines intersect in the point with approximate coordinates of (44,112).

The age at which both companies charge the same premium is 44 years

Step-by-step explanation:

You really just need a calculator for this but to solve by hand just simply separate all the variables and coefficients and then multiply them together at the end.

[tex]-9x^5y^2[/tex]

Since x = -1

[tex]-1^5[/tex] = [tex]-1*-1*-1*-1*-1[/tex] = -1

[tex]\frac{1}{3}^2= \frac{1}{3}*\frac{1}{3}=\frac{1}{9\\}[/tex]

It should be noted that the value of the expression 5 - 2 - 2 + 10 will be 11.

Mathematical operators like addition, subtraction, multiplication, and division are used to create expressions in writing.

You must substitute a number for each variable and carry out the arithmetic operations in order to evaluate an algebraic expression.

For example, x + 6 = 12. Since 6 + 6 equals 12, the variable x in the example above is equal to 6. We can substitute the variables with their values and then evaluate the expression if we know the values of our variables.

Based on the information illustrated, it should be noted that the value of the expression 5 - 2 - 2 + 10 will be 11.

x < -6 means that x is lesser than -6. Thus, C and D are wrong. A filled up dot means that -6 is also a possible number for x, but here it says that x is lesser than -6, so it cannot be -6 itself. Thus, B with the filled up dot is also wrong.

Answer:

The component form of the vector P'P is [tex]\left \langle -7, 2 \right \rangle[/tex]

Step-by-step explanation:

The component form of the vector that translates P(4, 5) to P'(-3, 7), is given as follows;

The x-component of the vector = The difference in the x-values of the point P' and the point P = -3 - 4 = -7

The y-component of the vector = The difference in the y-values of the point P' and the point P = 7 - 5 = 2

The component form of the vector P'P = [tex]\left \langle -7, 2 \right \rangle[/tex]

Step-by-step explanation:

Reason 3 is supposed to be prove

Triangle second and third can be shown to be similar using AA similarity when we take two angles between them.

In Euclidean geometry, two objects are similar if they have the same shape, or one has the same shape as the mirror image of the other.

In second and third triangle two angles whose measures are 24 degrees and 67 degrees are in both triangles, which is the condition of AA similarity.

To check AA similarity we have to check whether two angles are equal in two triangles to be similar.

Answer:

Cost of child movie = x = $8

Cost of adult movie = y = $10.25

Step-by-step explanation:

Let cost of child movie = x

Cost of adult movie = y

Now converting statements into mathematical expressions:

Hansen family bought 2 child and 2 adult movie tickets and paid $36.50.

[tex]2x+2y=36.50[/tex]

Owens family bought 5 child and 2 adult tickets and paid $60.50. [tex]5x+2y=60.50[/tex]

Let:

[tex]2x+2y=36.50--eq(1)\\5x+2y=60.50--eq(2)[/tex]

Subtract both equations:

[tex]2x+2y=36.50\\5x+2y=60.50\\- \:\:\: - \:\:\:\:\:\:\:\: -\\--------\\-3x=-24\\x=\frac{-24}{-3}\\x=8[/tex]

So, we get Value of x =8

Now, putting value of x in eq(1) to find value of y

[tex]2x+2y=36.50\\Put \: x=8\\2(8)+2y=36.50\\2y=36.50-16\\2y=20.5\\y=\frac{20.5}{2}\\y=10.25[/tex]

So, we get Value of y = 10.25

So,

Cost of child movie = x = $8

Cost of adult movie = y = $10.25
