Answer:

Option D: The number of multiple-choice question points plus the number of  short-answer question points is 80 is the correct answer.

Step-by-step explanation:

Given that:

Points worth of test = 80 points

There are Multiple choice questions worth 2 points and short answer questions worth 4 points.

2x+4y=80

Thus,

The number of multiple choice questions points plus the number of short answer question points is 80.

Hence,

Option D: The number of multiple-choice question points plus the number of  short-answer question points is 80 is the correct answer.

Answer:

I have attached a picture of the graph.

Step-by-step explanation:

So for 3 miles, they are charged $6 and for 5 miles, $8. This means that for 5-3 = 2 miles, they are charged $8-$6 = $2.

2 miles = $2

1 mile = $1

We will apply this charging rate for 3 miles since we know there is a flat fee added into it too.

3 miles = $3

Flat fee = $6 - $3

            = $3

That means that at 0 miles, there is a flat fee of $3, and so the graph would start at 3 on the x-axis even when the y-axis (representing the miles) is at 0 (0 miles).

You also know that for each mile, there is an increase of $1, so the graph should increase upwards at 1 dollar per 1 mile. I have attached the graph for you.

16/9 : 8/3 = 2/3

Answer:

17-3-5=9???

Step-by-step explanation:

The number expression is 9 = 17 - 3 - 5 if Daniel found 17 basketballs but 3 of them were broken and another 5 needed pumping. There were only 9 basketballs that could be used.

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.

We have:

"Daniel found 17 basketballs but 3 of them were broken and another 5 needed pumping. There were only 9 basketballs that could be used.’’

Let x be the total number of basketballs that can be used.

x = 17 - 3(broken) - 5(need to pump)

x = 17 - 3 - 5

x = 17 - 8

x = 9

9 = 17 - 3 - 5

Thus, the number expression is 9 = 17 - 3 - 5 if Daniel found 17 basketballs but 3 of them were broken and another 5 needed pumping. There were only 9 basketballs that could be used.

Answer:

Set A is a function

set B is not a function

Answer:

A: 7.5

Step-by-step explanation:

If the length is 5 inches longer than the width, we must multiply the width by 4 and add ten to figure out the perimeter. 7.5 x 4 = 30. 30 + 10 = 40.

Answer: Mount Everest: 8,849.87 meters, Mount Olympus: 2,919.07 meters

Step-by-step explanation: Part A: 5900     Part B: 5930.8         Part C: It's reasonable because part a's answer and part b's answer is pretty accurate and close enough to each other, so yes it is reasonable. But the estimate is very reasonable.

Answer:

nice 44 pts

Step-by-step explanation:

The given equations are

[tex]2x-3y=-1\cdots(i) \\\\y=x-1\cdots(ii)[/tex]

(a) Solution by graphing both the equations:

Graph for both the equations (i) and (ii) are in the figure. The point of intersection of both the graph is the solution of the equations.

From the graph, the point of intersection is (4,3)).

Hence, the required solution is (4,3).

(b) Solution by elimination method:

Equations (ii) can be written as -x+y=-1, now multiply it by 2, we have

[tex]-2x+2y=-2\cdots(iii)[/tex]

Add equations (i) and (iii), we have

2x-3y=-1

-2x+2y=-2

__________

[tex]\Rightarrow -3y+2y=-1-2\\\\ \Rightarrow -y=-3\\\\ \Rightarrow y=3.[/tex]

Putting the value of y=3 in equation (i), we have

[tex]2x-3\times 3=-1 \\\\\Rightarrow 2x=-1+9=8 \\\\\Rightarrow x=8/2=4[/tex]

Hence, the required solution is (4,4).

(c) Solution by substitution method:

Substituting the value of y from equation (ii) to equation (i), we have

[tex]2x-3(x-1)=-1 \\\\\Rightarrow 2x-3x+3=-1 \\\\\Rightarrow -x=-1-4=-4 \\\\\Rightarrow x=4[/tex]

Putting the value of x=4 in equation (i), we have

[tex]y=4-1=3[/tex].

Hence, the required solution is (4,3).

Answer:

231 ft²

Step-by-step explanation:

Given that :

Dimension of each side = 3.5 feets by 11 feets

Area of each side :

Length * width = (3.5 * 11) feets = 38.5 ft²

Number of sides = 6

Hence, number of square feets to paint :

Number of sides * area of each side :

6 * 38.5 ft²

= 231 ft²

Answer:

[tex]Tatiana = \$8.35[/tex]

Step-by-step explanation:

Given

[tex]Total = \$31.50[/tex]

[tex]Felicia = \$4.25[/tex]

[tex]Ingrid = 2 * Felicia[/tex]

[tex]Meiko = \$1.90 + Ingrid[/tex]

Required

Determine amount spent by Ingrid

We have that:

[tex]Ingrid = 2 * Felicia[/tex]

Substitute $4.25 for Felicia

[tex]Ingrid = 2 * \$4.25[/tex]

[tex]Ingrid = \$8.5[/tex]

We also have that:

[tex]Meiko = \$1.90 + Ingrid[/tex]

Substitute $8.5 for Ingrid

[tex]Meiko = \$1.90 + \$8.50[/tex]

[tex]Meiko = \$10.40[/tex]

The total can be represented as thus:

[tex]Felicia + Ingrid + Meiko + Tatiana = Total[/tex]

[tex]\$4.25 + \$8.50 + \$10.40 + Tatiana = \$31.50[/tex]

[tex]\$23.15+ Tatiana = \$31.50[/tex]

Collect Like Terms

[tex]Tatiana = \$31.50 - \$23.15[/tex]

[tex]Tatiana = \$8.35[/tex]

Answer:

1138

Step-by-step explanation:

From the information given:

We can represent it perfectly in an exponential form:

[tex]m = p(q)^x[/tex]

where;

p = initial value = 120

q = base of the exponential form

q = 1 + r

here; r = rate in decimal = 10% = 0.1

Then q can now be = 1 + 0.1 = 1.1

Replacing it into the exponential form, we get:

[tex]m = 120(1.1)^x[/tex]

where;

x = number of days and m = number of shoppers

Thus:

For the first day:

[tex]m = 120(1.1)^x[/tex]

m = 120

For the second day:

[tex]m = 120(1.1)^1[/tex]

m = 132

For the third day:

[tex]m = 120(1.1)^2[/tex]

m = 145.2

For the fourth day

[tex]m = 120(1.1)^3[/tex]

m = 159.72

For the  fifth-day

[tex]m = 120(1.1)^4[/tex]

m = 175.692

For the sixth-day

[tex]m = 120(1.1)^5[/tex]

m = 193.2612

For the seventh-day

[tex]m = 120(1.1)^6[/tex]

m = 212.58732

Thus; the total numbers of shoppers for the first 7 days is:

[tex]= 120+ 132 + 145.2 + 159.72 + 175.692+193.2612+212.58732[/tex]

= 1138.46052

≅ 1138
