Answer:

(C). 6

Step-by-step explanation:

[tex]3\frac{9}{10}[/tex] + [tex]5\frac{1}{x}[/tex] = [tex]9\frac{1}{15}[/tex]

[tex]5\frac{1}{x}[/tex] = [tex]9\frac{1}{15}[/tex] -  [tex]3\frac{9}{10}[/tex] =  [tex]6\frac{2-27}{30}[/tex] = [tex]5\frac{32-27}{30}[/tex] = [tex]5\frac{5}{30}[/tex] = [tex]5\frac{1}{6}[/tex] ⇒ x = 6

Step-by-step explanation:

Answer:

the answer is 11.

if 16 inches of wire cost 48 cents your goal i to figure out how many inches of wire cots 33 cents to do so you have to find out how many cents each inch is. to do that you have to divide 48 by 16 and you get 3 so that mean that 1 inch costs 3 cents. after you figure that out you do 33 divided by 3 and you get 11. the answer is 11 inches costs 33 cents.

Step-by-step explanation:

18 - [ 18 - [ 18 - ( 18 - 1)]]

= 18 - [ 18 - [ 18 - 17]]

=18 - [ 18 - 1]

= 18 -17

=1

We will see that as x tends to ± ∞, the function tends to -∞.

We define the end behavior as how the function behaves as x tends to very large, in absolute value, values.

In this case we have a quadratic equation:

f(x) = -0.5*x^2 - 3*x - 4

Here you can see that the leading coefficient is negative, thus, the arms of the graph will go downwards.

This means that in the limits of x ⇒ ∞ and x ⇒ -∞, the function will tend to negative infinity.

Then the end behavior can be written as:

Answer:

Yes, y is a function of x.

Explanation:

Based on the information given, the equation will be y = 9.6x.

From the equation given, it was stated that the amount Lin's sister earns at her part-time job is proportional to the number of hours she works and that she earns $9.60 per hour.

Therefore, writing the equation in the form y=kx to describe this situation will be:

y = (9.6 × x)

y = 9.6x

Answer:

c÷0.35

Step-by-step explanation:

Because you are trying to find the amount it costs for 1s, you need to divide 0.35s by 0.35 to get 1s, and you need to divide c by 0.35 as well. So, you get c÷0.35

Answer:

74.5

Step-by-step explanation:

The median is the middle number of a data set.

However, when the total amount of numbers in the data set add up to an even number, such as this one adding up to 8, we take the middle number, or 4, and the number above it, or 5. 72 and 77 are numbers 4 and 5 when the data set is in numerical order, so now we add 72 and 77, and get 149.

Finally, we divide 149/2 because there are 2 numbers contributing to the median total. The answer to 149/2 is 74.5.

Answer:

The answer is 74.5

Step-by-step explanation:

The median is the number in the middle the two numbers that are in the middle is 72 and 77. Arrange the data in an ascending order and the median is the middle value. If the number of values is an even number, the median will be the average of the two middle numbers.

Answer:

75 in²

Step-by-step explanation:

From the diagram, you can see that the shape is made up of a square and 4 triangles. (We know it's a square as the width = length).

First, find the area of the square.

Area of a square = width x length = 5 x 5 = 25 in²

All the triangles are the same, so we need to find the area of one of the triangle and multiply it by 4.

Area of a triangle = [tex]\frac{1}{2}[/tex] x base x height = [tex]\frac{1}{2}[/tex] x 5 x 5 = 12.5 in²

So total area of 4 of these triangles = 4 x 12.5 = 50 in²

Therefore the total surface area = 25 + 50 = 75 in²

Answer:

$45

Step-by-step explanation:

shoes=$75

jacket=40% of shoes

         =2/5x75

          =$30

total=$75+$30=$105

change=$150-$105=$45

Answer:

She has $30 dollars left over.

Step-by-step explanation:

We already know she spent $75 on the shoes. So, if the jacket was 40% of what the shoes cost, we can start solving.

Therefore, she has $30 leftover.

Whichever method you use, the x coefficient is 13.

Step-by-step explanation:

sum of angle 1 and angle 2 is 180°

so,

4x + 14 + 8x + 10 = 180

12x + 24 = 180

12x = 180 - 24 = 156

x = 156/12 = 13

x = 13°

therefore, value of x is 13 and option C is correct.

Answer:

15 and 18

Step-by-step explanation:

33 split into groups of 5 and 6

The good approximation for the value of the function, f(x), when x = 18 is -2.

Given

A line of best fit is for the set of points in the table.

The standard form of the linear equation is;

[tex]\rm y =mx+c[/tex]

Where m is the slope of the line and c is the intercept.

Therefore,

By using the equation for the line of best fit, what is a good approximation for the value of the function, f(x), when x = 18 is;

[tex]\rm f(x) = -0.86x + 13.5\\\\f(18)= -0.86(18)+13.5\\\\f(18)= -15.48 + 13.5 \\\\ f(18)= -1.98[/tex]

Hence, The good approximation for the value of the function, f(x), when x = 18 is -2.

Answer:

m = -1

Step-by-step explanation:

Formula we'll use: [tex]\frac{y2}{x2} -\frac{y1}{x1} =m[/tex]

m = slope.

y2 = -4

x2 = -5

y1 = 6

x1 = 5

Substitute -4, -5, 6, 5 into the formula:

Subtract both top and bottom:

m = -10/-10

m = -1

The perimeter of a shape is the sum of its side lengths

The corresponding side length for shape B is 20 feet

The length-perimeter ratio is given as:

Ratio = Length : Perimeter

For both shapes, we have:

12 : 36 = Length : 60

Express as fraction

[tex]\frac{12}{36} = \frac{Length}{60}[/tex]

Multiply both sides by 60

[tex]Length = \frac{12}{36} * 60[/tex]

[tex]Length =20[/tex]
