Answer:

0.75 Of a cup

Step-by-step explanation:

Answer:

0.75 cups

Step-by-step explanation:

1 fluid ounce is 0.125 cups (1/8th of a cup)

Hence,

6 fluid ounces = 0.125 x 6 = 0.75 cups

Answer:

(3,8)

Step-by-step explanation:

THIS IS AN EXAMPLE FOR ANY PROBLEM!!

Get the equation in the form y = ax2 + bx + c.

Calculate -b / 2a. This is the x-coordinate of the vertex.

To find the y-coordinate of the vertex, simply plug the value of -b / 2a into the equation for x and solve for y. This is the y-coordinate of the vertex.

- Good luck!

Answer:1. Use substitution to solve the system of equations:

   -x + 2y=7

    x - 3y = 3

2. Solve the system of equations by the elimination method

a.  2x+ y = -17

   x - y = 2

b. 3x + y = -15

  x + 2y = -10

Answer:

(0, 1)

Step-by-step explanation:

You can solve this by using the substitution or elimination method. For this problem, I'm going to use the substitution method. First, rewrite -4x-2y=-2 in slope-intercept form, which would be y=-2x+1. Substitute the y value in -9x+3y=3 (which would be -9x+3(-2x+1)=3) and solve.

-9x+3(-2x+1)=3

-9x-6x+3=3

-15x=0

x=0

Now, substitute the x value in for the x in any equation. You can do -4(0)-2y=-2 or -9(0)+3y=3. I'm going to use -9(0)+3y=3.

-9(0)+3y=3

3y=3

y=1

Answer:

The answer is 2.6

Answer:

[tex]0.025 = 2.33\sqrt{\frac{0.79*0.21}{n}}[/tex]

Option d.

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].

The margin of error is:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

79 percent of adults age 18 years and older in the United States use the Internet.

This means that [tex]\pi = 0.79[/tex]

98% confidence level

So [tex]\alpha = 0.02[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.02}{2} = 0.99[/tex], so [tex]Z = 2.33[/tex].

Which of the following should be used to find the sample size (n) needed?

We have to find n for which [tex]M = 0.025[/tex]

So the equation is:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

[tex]0.025 = 2.33\sqrt{\frac{0.79*0.21}{n}}[/tex]

Option d.

Answer:

D. 1/8

Step-by-step explanation:

A unit fraction is a fraction with numerator of 1.

Answer:

D 1/8 Because unit factions always have a one as the numarator

Answer:

[tex]Total = 104\ hrs[/tex]

Step-by-step explanation:

Given

[tex]Monday = 15\ hrs[/tex]

[tex]Tuesday = 13\ hrs[/tex]

[tex]Wednesday = 24\ hrs[/tex]

Required

Determine the hours of practice over 6 days

First, we calculate the hours for the given 3 days.

[tex]Hours = Monday + Tuesday + Wednesday[/tex]

[tex]Hours = 15\ hrs + 13\ hrs + 24\ hrs[/tex]

[tex]Hours = 52\ hrs[/tex]

The hours of practice for the other three days is also 52 hours.

So, the total is:

[tex]Total = 52\ hrs + 52\ hrs[/tex]

[tex]Total = 104\ hrs[/tex]

Answer:

Answer:

(4,18); (6,22); (8,26)

Step-by-step explanation:

Plug in the numbers 4, 6, and 8, in for d using the equation.

c=2d+10

c=2(4)+10

c=8+10

c=18

(4,18)

c=2d+10

c=2(6)+10

c=12+10

c=22

(6,22)

c=2d+10

c=2(8)+10

c=16+10

c=26

(8,26)

Answer:

14

18

22

26

Step-by-step explanation:

c = 2d + 10

1st one: substitute 2 for d

c = 2 x 2 + 10

c = 14

2nd one: substitute 4 for d

c = 2 x 4 + 10

c = 18

3rd one: substitute 6 for d

c = 2 x 6 + 10

c = 22

4th one: substitute 8 for d

c = 2 x 8 + 10

c = 26

Sides of the triangle = 3, 4, 5

Here, one thing to remember is, you have to put 5 as the "Hypotenuse" (Longest side) & smaller one's as Base & Perpendicular.

Hope this helps!

Answer:

C

Step-by-step explanation:

7 - 2 = 5

11 - 3(2)

11 - 6 = 5

4(2) - 3

8 - 3 = 5

C is the only one that doesn't equal 5

Answer:

78

Step-by-step explanation:

The range is the difference between the highest and lowest number:

4, 5, 8, 18, 21, 43, 82

The highest number is 82 and the lowest is 4

82 - 4 = 78

The range is 78

Question:

You are making sandwiches for a large party. Each sandwich has two slices of bread, one slice of turkey, two slices of cheese, three slices of tomato and 5 slices of cucumber. How many sandwiches will you get from 10 slices of bread and 20 slices of cucumber? assuming you have plenty of everything

Answer:

4 sandwiches

Step-by-step explanation:

Given

1 Sandwich contains:

[tex]Bread = 2\ slices[/tex]

[tex]Turkey = 1\ slice[/tex]

[tex]Cheese = 2\ slices[/tex]

[tex]Tomato = 3\ slices[/tex]

[tex]Cucumber = 5\ slices[/tex]

Required

Number of sandwiches from 10 slices of bread and 20 slices of cucumber?

Since we are to assume that every other thing is in abundance, we will only consider the unit amount of bread and cucumber

[tex]Bread = 2\ slices[/tex]

[tex]Cucumber = 5\ slices[/tex]

Express as ratio

[tex]Bread : Cucumber = 2 : 5[/tex]

When the ratio is multiplied by 5, the slice of cucumber (25) will exceed the available slices (20).

So, we multiply by 4

[tex]Bread : Cucumber = 2*4 : 5*4[/tex]

[tex]Bread : Cucumber = 8 : 20[/tex]

This implies that:

8 slices of bread and 20 slices of cucumber are used

Hence:

4 sandwiches can be made
