A surfboard was originally priced at $75 but went on sale for 60% off. If Quincy bought the surfboard and paid 10% sales tax, how much did he pay in total?

Answers

Answer:

$49.5

Step-by-step explanation:

60% of 75$ = 45$

60/100 x 75/100   = 4500

4500/100 = 45

10% sales tax on 45$ = 49.50$

10/100 x 45/100 = 450

450/100 = 4.5

4.5 + 45 = $49.5

Answers

I will be using * as the degree symbol

Answer:

a) 105*

b) 105*

c) 105*

Step-by-step explanation:

a) the car is facing west or left. If you imagine it spinning completely around to face east, it would be turning 180*. However it does not go that last 75* shown on the map. So 180 - 75 = 105

b) The angle diagonal to the 105* angle is also 105*. And since 3rd and 4th street are parallel so is the angle you are trying to find

c) This is the same turn as the first one but opposite

I need a set of coordinates to model a relation that is a linear function quick please.

Answers

Answer:

y=2x+1

Step-by-step explanation:

The linear function is a function that has a straight line graph.

Response:

A set of coordinate that model a linear function is presented as follows;

{(0, 5), (1, 8), (2, 11), (3, 14), (4, 17), (5, 20)}

Method by which the above set of coordinates is obtained

A linear function is a function that can be written in the form; y = m·x + c

Where;

m = The slope of the graph is a constant

c = The y-intercept of the graph is a constant

Therefore,

Therefore, a set of coordinates can be obtained by setting the values of m and c as follows;

When m = 3, and c = 5, we have;

y = 3·x + 5

Using the above equation, we get;

[tex]\begin{tabular}{|c|c|} \underline{x} & \underline{y = 3 \cdot x + 5}\\0&5\\1&8\\2&11 \\3&14\\4&17\\5&20\end{array}\right][/tex]

Using the above table of values, a set of coordinates that model a linear function is therefore;

{(0, 5), (1, 8), (2, 11), (3, 14), (4, 17), (5, 20)}

Answer:

7m^3-11m^2+5m+17

Step-by-step explanation:

it'll be really hard to show work so just trust me on this one-

hope it helps <3

For m^3 : Because you are subtracting a negative from a negative, that means you are adding, therefore the first part should be 7m^3

For m^2 : because you are subtracting a positive from a negative, that means you are subtracting, so it would be -11m^2

For m : because you are subtracting a negative from zero, it would turn into a positive, making it just 5

For the constant : subtracting positive 8 from negative 9 makes it a positive from the double negative. Therefore you would add 8+9, giving you 17

FINAL ANSWER : B. (7m^3)-(11m^2)+5m+17

The circle graph represents a family’s monthly budget. If the total monthly budget is $6,500.00, how much more does the family spend on housing than food?

Answers

Answer:

Use the percentages to help you.

Ask yourself, what is 25% of $6,500.00?

Turn your percent into a decimal which is 0.25

then multiply $6,500 by 0.25

you should get 1625.

Find the amount of money spent on the food and find the difference of the two.

C. $390.00

Explanation:

Housing: 6,500/.25= $1,625
Food: 6,500/.19= $1,235

Subtraction:
$1,625 - $1,235= $390

The family spends $390.00 more dollars in housing than food.
