Step-by-step explanation:

Because < this means less than. So therefore 5 is less than 12

Given:

Samantha purchased dinner at a restaurant and spent $38 on food and beverages.

Rate of sales tax = 7%

To find:

How much will Samantha pay for sales tax in dollars and cents?

Solution:

Amount spent on food and beverages = $38

Rate of sales tax = 7%

Sales tax = 7% of $38

[tex]\text{Sales tax}=\dfrac{7}{100}\times 38[/tex]

[tex]\text{Sales tax}=\dfrac{266}{100}[/tex]

[tex]\text{Sales tax}=2.66[/tex]

Therefore, the sales tax is $2.66.

Answer:

Number of 7 inch plate = 8

Number of 12 inch plate = 7

Step-by-step explanation:

There are 15 plates in a kitchen cabinet. The diameter of each plate is either 7in or 12in. The diameter of all 15 plates combined is 140in. Which system of equations can be used to find the number of 7in plates, x , and the number of 12in plates, y , that are in the cabinet?

Given that :

Total Number of plates = 15

Diameter of each plate : 7 in or 12 in

Diameter of all 15 plates = 140 in

Let number of 7 in and 12 in diameter plates = x and y respectively ;

x + y = 15 - - (1)

7x + 12y = 140 - - - (2)

x = 15 - y

Substitute x = 15 - y in (2)

7(15 - y) + 12y = 140

105 - 7y + 12y = 140

105 + 5y = 140

5y = 140 - 105

5y = 35

y = 7

From x = 15 - y

x = 15 - 7

x = 8

Number of 7 inch plate = 8

Number of 12 inch plate = 7

Answer:

Tim purchased 6 video games.

Step-by-step explanation:

Let's set the number of games Time purchased as x.

Due to each game costing $25, the total amount of money used on buying games would be ($25)x.

Hence, as the total amount of money used to buy both the console and the video games would be $350, the equation can be set as:

[tex]\$25x + \$200 = \$350[/tex]

[tex]\$25x = \$(350 - 200)[/tex]

[tex]x = \frac{\$150}{\$25}[/tex]

[tex]x = 6[/tex]

Therefore, Tim purchased 6 video games.

Step-by-step explanation:

A perpendicular bisector is a line that cuts a line segment connecting two points exactly in half at a 90 degree angle. To find the perpendicular bisector of two points, all you need to do is find their midpoint and negative reciprocal, and plug these answers into the equation for a line in slope-intercept form.

Answer/Step-by-step explanation:

9. 17x = 16x + 5 (alternate exterior angle)

17x - 16x = 5

x = 5

Measure of bolded angle = 17x = 17 * 5 = 85

10. 21x - 6 = 20x (corresponding angels)

21x - 20x = 6

x = 6

Measure of bolded angle = 20x = 20(6) = 120

11. (x + 95) + (x + 105) = 180 (linear pair angles)

2x + 200 = 180

2x = 180 - 200

2x = -20

Divide both sides by 2

x = -10

Measure of bolded angle = x + 105 = -17 + 105 = 88°

12. 12x - 4 = 11x + 3 (vertical angles)

Collect like terms

12x - 11x = 4 + 3

x = 7

Measure of bolded angle = 11x + 3 = 77 + 3 = 80°

Answer:

75 seconds

Step-by-step explanation:

Here, we want to get her time 6 weeks ago.

We shall have an exponential model to link this all up

The exponential model would look like;

y = I(1 - r)^n

where y is the present time

I is the initial time she started with which we are calculating

r is the rate of change which is 2% = 2/100 = 0.02

n is the week number which is 6 in this case

So we have;

66 = I(1 - 0.02)^6

66 = I(0.98)^6

I = 66/0.8858

I = 74.5 seconds

This is approximately 75 seconds

Her time 6 weeks ago is 75 seconds

Step-by-step explanation:

Sum of angles in this pentagon = 540°.

Therefore 13x + 241 = 540, x = 23

Hence Angle P = 4(23) + 2 = 94°.

The measure of angle P is 94°

"It is a polygon with five vertices and five sides."

For given example,

We know, the sum of all interior angles of a pentagon is 540°

⇒ ∠P + ∠Q + ∠R + ∠S + ∠T = 540°

⇒ (4x + 2)° + (132)° + (4x - 10)° + (5x - 11)° + 128° = 540°

⇒ 4x + 4x + 5x + 2 + 132 - 10 - 11 + 128 = 540

⇒ 13x + 241 = 540

⇒ 13x = 299

⇒ x = 23

So, the measure of angle P would be,

4x + 2

= 4 (23) + 2

= 94°

Therefore, the measure of angle P is 94°

The percentage of coach passengers who did not check their bags will be 43.82 %.

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.

It is given that the total number of passengers is, 162 of which 71 bags didn't check while 91 bags got checked.

We have to find the percentage of coach passengers who did not check their bags.

It is found by dividing the total number of passenger bags not checked by the total number of passengers.

=71 / 162 × 100

=43.82 %

Thus, the percentage of coach passengers who did not check their bags will be 43.82 %.

The sum of angle in the triangle BCD is 180 degrees

Given;

<B = 4x  -14

<C = x - 1

<D = 6x + 8

Required

Find x

Since <B + <C + <D = 180, hence;

4x - 14 + x - 1 + 6x + 8 = 180

11x -7 = 180

11x = 180+7

11x = 187

x = 187/11

x = 17

Hence the value of x is 17

Answer:

0.0476

Step-by-step explanation:

To solve 20/420,

We first reduce the numerator and denominator to its lowest terms(we are not using long division method) :

In the fraction 20/420, we cancel out the zeros =2/42

In the fraction 2/42, 2 will divide numerator and denominator so =1/21

To find the actual quotient, we are sure to get a result of decimal number since numerator is already smaller than denominator,

Therefore 1/21= 0.0476 to 4 decimal places

Note : we add zero to the numerator till it can be divided by 21(even with a remainder) hence the "0.0" before 4

Step-by-step explanation:

The y intercept is when x = 0.

In the function y=-2x+8, when x=0, y=8.

In the graph, when x=0, y=8. You can see on the x axis 0 is in the middle, and if you move up the y axis, you see the line intersects y=8.

Thus both have the same y intercepts of 8.
