Answer:

14oz soup/ person

Step-by-step explanation:

the answer would be 14oz of soup/person

multiply 7 (cans of soup) by 16 (oz per can)

7*16=112

divide 112 (oz of soup total) by 8 (number of people feeding)

112/8=14

Answer:

3 hours

Step-by-step explanation:

Total cost = 144 + 80h

Where h = number of hours

How many hours can Michelle afford to pay the mechanic if she can spend no more than $384?

384 = 144 + 80h

Subtract 144 from both sides

384 - 144 = 144 + 80h - 144

384 - 144 = 80h

240 = 80h

Divide both sides by 80

h = 240 / 80

= 3

h = 3 hours

Answer:

English homework = 19/30h or 38 minutes

Total time spent = 22/15h or 88 minutes

Step-by-step explanation:

Mathematics homework = 5/6h

= 5/6 × 60

= 300/6

= 50 minutes

He took 1/5 h less to complete his english homework.

English = 5/6h - 1/5h

= 25h-6h/30

= 19/30h

= 19/30 × 60

= 1,140/30

= 38 minutes

English homework = 19/30h or 38 minutes

Total time spent on his homework = mathematics homework + English homework

= 5/6h + 19/30h

= 25h+19h/30

= 44/30h

= 22/15h

= 22/15 × 60

= 1,320 / 15

= 88 minutes

Answer:

  (0.5, -2.5)

Step-by-step explanation:

Each of the coordinates of B(1, -5) is multiplied by the scale factor, 0.5:

  B' = (0.5·1, 0.5·(-5)) = (0.5, -2.5)

The coordinates of B' are (0.5, -2.5).

Answer:

D 3

Step-by-step explanation:

Answer:

D) 3

Step-by-step explanation:

The rise of the line is 3 and the run is 1. Rise/Run is the answer so in this case, it is 3/1 or 3. Since the line rises left to right, the slope is positive.

Answer:

Discount selling price= $172.5

Step-by-step explanation:

Giving the following information:

Selling price= $230

Discount rate= 25%

To calculate the discount selling price, we need to use the following formula:

Discount selling price= selling price*(1 - discount rate)

Discount selling price= 230* (1-0.25)

Discount selling price= $172.5

Answer:

1/2x+5=10

subtracting 5 from both sides 1/2x+5-5=10-5

1/2x=5

divide both sides by 1/2

1/2x÷1/2=5÷1/2

x=5×2/1

x=10

Answer:

The constant of proportionality is 1/25.

Step-by-step explanation:

Chart values:

 a    |    b

75         3

200      8

1525   61

10       0.4

To find the constant, divide your "b" values by your "a" values.

3/75 simplifies to 1/25 (GCF is 3)

8/200 simplifies to 1/25 (GCF is 8)

61/1525 simplifies to 1/25 (GCF is 61)

0.4/10 becomes 4/100, which simplifies to 1/25 (GCF is 4)

Since all four come to the same constant, 1/25 is the constant of proportionality.

The equation here would be:

[tex]b=\frac{1}{25}a\\b=\frac{a}{25}[/tex]

The first one is normally, the second is in slope form.

Answer:

$2.25

Step-by-step explanation:

Let c represent the price of cheese pizza and let p represent the prize of pepperoni pizza

3c + 2p= 11.75

2c + 1p = 7

Solve using elimination method

3c + 2p= 11.75 × 2

2c + 1p = 7 × 3

6c + 4p = 23.5

-

6c + 3p = 21

p = 2.5

Substitute 2.5 for p in equation 1

3c + 2p= 11.75

3c + 2(2.5) = 11.75

3c + 5 = 11.75

3c = 11.75-5

3c = 6.75

c= 6.75/3

c= 2.25

Hence the price of one slice of cheese pizza is $2.25

Step-by-step explanation:

1-2sin²∝=cos 2∝

1-2sin²(105)=cos(2×105)

=cos 210

=cos (180+30)

=-cos 30

[tex]=-\frac{\sqrt{3}}{2} \\[/tex]

The correct answer is option A which is the value of the expression is -√3/2.

The branch of mathematics sets up a relationship between the sides and the angles of the right-angle triangle termed trigonometry.

The expression will be solved as:-

1-2sin²∝=cos 2∝

1-2sin²(105)=cos(2×105)

1-2sin²(105=cos 210

1-2sin²(105=cos (180+30)

1-2sin²(105=-cos 30

1-2sin²(105 = -√3/2.

Therefore the correct answer is option A which is the value of the expression is -√3/2.

Step-by-step explanation:

The domain is the set of x-values for which the relation is defined.

The domain of the graph will be -2 ≤ x ≤ 9 which is shown in the given figure.

The domain of the function includes all possible x values of a function, and the range includes all possible y values of the function.

The domain of a graph is the set of all possible input values (also called the independent variable) that can be plotted on the graph. In other words, it is the range of values that the horizontal axis (also called the x-axis) of the graph covers.

To determine the domain of a given graph, you will need to look at the labels and scale of the x-axis.

The domain of a graph is the set of all possible input values in intervals as -2 ≤ x ≤ 9 that can be plotted on the graph.

Thus, the domain of the graph will be  -2 ≤ x ≤ 9, as indicated in the illustration.
