Make a table of ordered pairs for the equation.



y=−1/3x+1



Then plot two points to graph the equation.

Answers

When making a table, be on the safe side and do 2 positive and 2 negative x values.
Choose an x value and substitute it into the equation. The value of y is the y-value.

(3, 0)
(0, 1)
(-3, 2)
(-6, 3)

Then, choose two points and draw a straight line through them, you have a graph.

Hope this helps!

We want to make a table of ordered pairs for the given equation, and then graph two of these points to graph the equation.

We have the equation:

y = (-1/3)*x + 1

We can make the table:

[tex]\left[\begin{array}{ccc}x&y\\-1&\\0&\\1&\\3&\end{array}\right][/tex]

To complete the table, we just need to evaluate the given equation in these x-values. We will get:

y(-1) = (-1/3)*(-1) + 1 = 1/3 + 1 = 4/3

y(0) = (-1/3)*0 + 1 = 1

y(1) = (-1/3)*1 + 1 = 2/3

y(3) = (-1/3)*3 + 1 = 0

Now we just complete the table with the values that we got:

[tex]\left[\begin{array}{ccc}x&y\\-1&4/3\\0&1\\1&2/3\\3&0\end{array}\right][/tex]

Now to graph the equation, we can graph two of these points, for simplicity I will graph (0, 1) and (3, 0).

Once the points are graphed, we just need to draw a line that connects them. The graph can be seen below.

A parking lot has the shape of a rectangle. A scale drawing for the parking lot measures 6cm by 20cm. The scale is 1cm : 15m. Find the area of the parking lot.

Answers

1 cm = 15 m

so 6 cm = (6 * 15) = 90 m
and 20 cm = (20 * 15) = 300 m

A = L * W
A = 300 * 90
A = 27000 m^2 <=

Answer:

The answer for the area of the parking lot is 27,000m²

Step-by-step explanation:

Given that the shape of the parking lot is a rectangle we can model the area using the formula for area of a rectangle Which is

A= length *width

Step two :

Given length 20cm

Width 6cm

Furthermore the scale is

1cm:15m

That is 1cm represents 15m on paper

Therefore the length in meters

=20*15=300m

Width in meter

=6*15=90m

Area =300*90

Area =27,000m²

The total number of candies are 3¹² if there are  (3⁶)² . 3⁰ candies in a store; the answer is 3¹² candies option (D) 3¹² is correct.

What is integer exponent?

In mathematics, integer exponents are exponents that should be integers. It may be a positive or negative number. In this situation, the positive integer exponents determine the number of times the base number should be multiplied by itself.

It is given that:

The number expression is:

= (3⁶)² . 3⁰

As we know, from the properties of the integer exponent:

After using the properties of the integer exponent:

(3⁶)² = 3¹²

3⁰ = 1

(3⁶)² . 3⁰ = 3¹²

Thus, the total number of candies are 3¹² if there are  (3⁶)² . 3⁰ candies in a store; the answer is 3¹² candies option (D) 3¹² is correct.

Barney has 16 1/5 yards of fabric. To make an elf costume, he needs 5 2/5 yards of fabric. How many costumes can Barney make?

Answers

16 1/5 yards divided by 5 2/5 =3. He can make 3 costumes.

Answer:

Barney can make 3 costumes

Step-by-step explanation:

T = 16 1/5 = 81/5 yards

O = 5 2/2 = 27/5 yards/costume.

We have the total fabric (T) and the unitari costume requirement (O). Now, if we want to know the amount of costumes that Barney can make, we can divide total fabric (T) by the unitari costume requirement (O), the result will be the amount of costumes (A).

[tex]A = \frac{T}{O}=\frac{\frac{81}{5}}{\frac{27}{5}} =\frac{81*5}{5*27} =\frac{81}{27}\\A = \frac{81}{27} =\frac{9}{3} = 3 costumes[/tex]

Finally, we can conclude that Barney can make 3 costumes.

There are 35 more musicians in the String section of a city Symphony Orchestra than in its Brass section. There are 29 musicians in the Brass section. 1. How many musicians in all are in the String and Brass sections of the Symphony Orchestra?

Answers

x = string section
y = brass section

x = y + 35
y = 29 .....there are 29 in the brass section

x = 29 + 35
x = 64...there are 64 in the string section

for a total of : 64 + 29 = 93 total musicians <==

Final answer:

There are a total of 93 musicians in both the String and Brass sections of the Symphony Orchestra, with 29 in the Brass and 64 in the String section.

Explanation:

To determine how many musicians are in both the String and Brass sections of the Symphony Orchestra, we start by noting that there are 29 musicians in the Brass section. Since there are 35 more musicians in the String section, we add 35 to the number of Brass musicians to find the total in the String section:

Number of musicians in the String section = Number of musicians in the Brass section + 35 = 29 + 35 = 64 musicians.To find the total number of musicians in both sections, we then add the number of musicians in the Brass section:Total number of musicians in both sections = Number of musicians in the Brass section + Number of musicians in the String section = 29 + 64 = 93 musicians.

the number of students enrolled in school increased by 12% from last year to this year. The enrollment last year was 15,500. What is the enrollment this year?

Answers

Final answer:

To find the enrollment this year, calculate 12% of last year's enrollment and add it to the enrollment from last year. The enrollment this year is 17,360.

Explanation:

To find the enrollment this year, we need to calculate 12% of last year's enrollment and add it to the enrollment from last year.

Calculate 12% of 15,500: 12% × 15,500 = 0.12 × 15,500 = 1,860.Add 1,860 to last year's enrollment: 15,500 + 1,860 = 17,360.

Therefore, the enrollment this year is 17,360.

melissa has 14 reports to file, if each report takes an average of 1 hour and 15 mins, how long would it take to file 70% of them?

Answers

It would take 12 hours and 15 minutes

Answer:

12 hours 15 min

Step-by-step explanation:

Melissa has 14 reports to file.

She file 70% of report. She takes average of 1 hour and 15 minutes for each report.

First we find number of reported by Melissa.

Number of reported = 70% of 14

                                        = 9.8

1 hour 15 min [tex]=\dfrac{5}{4}[/tex] hours

For 1 report of file [tex]=\dfrac{5}{4}[/tex] hours

For 9.8 reports of file [tex]=9.8\times \dfrac{5}{4}\approx 12.25[/tex] hours

She will take 12.25 hours to report 70% of them.

12.25 hours = 12 hours 15 min

Hence, Melissa will take 12 hours 15 min to file 70% of report.

How many peptide bonds are present in a polypeptide that contains 45 amino acids?

Answers

44 peptide bonds. There are n-1 peptide bonds, where n is the amount of amino acids. This is because there are two termini on a polypeptide that makes it "hang off." It is like linking up a chain, if there are two that must bond together then they cannot bond with another chain, therefore there is always one less bond than the total amount of amino acids.
Final answer:

A peptide bond forms between two amino acids by a dehydration synthesis reaction. The number of peptide bonds in a polypeptide is always one less than the total number of amino acids. Therefore, in a polypeptide with 45 amino acids, there would be 44 peptide bonds.

Explanation:

A peptide bond is a chemical bond that forms between two amino acids when a carboxyl group of one amino acid reacts with the amino group of the other amino acid, releasing a molecule of water. This is a dehydration synthesis reaction, and it is how amino acids are linked together to form a polypeptide.

In a polypeptide chain, the number of peptide bonds present is always one less than the total number of amino acids. This is because each amino acid has one peptide bond with the next amino acid in the chain, except the last one. Hence, for 45 amino acids, there would be 44 peptide bonds.
