Martina started with 228 boxes of cookies and sold the same number each day for 4 days. After 4 days of selling, she was left with 100 boxes of cookies. Enter the slope of the line representing the change in Martina's inventory of cookies over this period of time.

Answers

Answer:

[tex]m = -32[/tex]

Step-by-step explanation:

Let x = days and y = box of cookies

So, we have:

[tex](x_1,y_1) = (0,228)[/tex] -- When she started

[tex](x_2,y_2) = (4,100)[/tex] --- After 4 days

Required

Determine the slope

The slope (m) is calculated using:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{100 - 228}{4 - 0}[/tex]

[tex]m = \frac{-128}{4}[/tex]

[tex]m = -32[/tex]

The slope is -32

Colton solved an equation incorrectly, as shown below:
Step 1: x - 13 = 26
Step 2: x = 26 - 13
Step 3: x = 39
Which statement best explains why Step 2 is incorrect in Colton's solution? (4
points)
He did not divide 26 by 13.
He did not multiply 26 by 13.
O He did not subtract 13 from 26.
He did not add 13 to 26.

Answers

Answer:

He didn't add 13 to 26

Step-by-step explanation:

he would need to add -13+13 to get rid of it. and add 13 on the other side 13+26

A business traveler was wondering how the taxi meters in a particular city work. She kept track of the distance traveled on each of her taxi rides and the amount
she paid for each of her fares. She then plotted the data points and found that while they didn't exactly form a line (probably due to varying times spent stuck in
traffic), they could be approximated by the line y = 1.75x+2.25, where x is the distance traveled in miles and y is the fare in dollars. According to the model, about
how much will a 3 mile ride cost?
A. $5.25

B. $6.75

С. $7.50

D. $8.50

Answers

C because you plug 3 in for x and the equation becomes 1.75(3)+2.25=5.25+2.25=7.50

Amy needs to buy 12 notebooks and a pack of pens from the store. The pack of pens cost $2.50 and she has a budget of $30. Which inequality represents the situation if a represents
the maximum amount she can spend on each notebook?
A 12.6 +2.50 > 30
B) 12 +2.50.3 < 30
C) 12. + 2.50 < 30
D 12 +2.50 < 30

Answers

I think it’s c, because if the . next to the 12 means x then yes. There should be an c near 12 because we have no clue how much the notebooks are. If the . doesn’t mean x then it should be d.

Please find the areas for these different shapes it would really help tysm

Answers

1-
Answer:
12

Explanation:
Let’s divide the shape into two triangles and a rectangle.
triangle area = base x height /2
= 2 x 4 /2
= 8 / 2
= 4
The other triangle is identical, so also 4.
Rectangle area = length x width
= 1 x 4
= 4
Add them: 4 + 4 + 4 = 12, which is the total area.

Determine the slope-intercept equation of a line with a slope of 3/2 that passes through (2, -1).

Answers

Answer:

[tex] \orange{ \bold{y = \frac{3}{2}x -4 }}[/tex]

Step-by-step explanation:

Slope of line (m) = [tex] \frac{3}{2} [/tex]

Line passes through the points [tex] (2,\:-1)=(x_1, \:y_1)[/tex]

Equation of line in point slope form is given as:

[tex] y-y_1 =m(x-x_1)[/tex]

Plug the values of m, [tex] x_1\: \&\: y_1[/tex] in the above equation, we find:

[tex]y - ( - 1) = \frac{3}{2} (x - 2) \\ \\ y + 1 = \frac{3}{2}x - \frac{3}{2} \times 2 \\ \\ y + 1 = \frac{3}{2}x -3 \\ \\ y = \frac{3}{2}x -3 - 1 \\ \\ \purple{ \bold{y = \frac{3}{2}x -4 }}\\ \\ [/tex]

This is the required equation of line in slope-intercept form.

2/5+7/15 in its simplest form

Answers

Answer:

13/15

Step-by-step explanation:

First convert the fractions to have a common denominator

2/5 = x/15

Cross multiply

2 × 15 = 5 × x

30 = 5x

Divide both sides by 5 to isolate the variable

30 ÷ 5 = x

6 = x

Plug x into the new fraction

6/15

Now add this to the other fraction

6/15 + 7/15

Only add the numerators. The denominators will remain the same number

6 + 7 / 15

13/15

It cannot be reduced anymore so this is simplest form

V=πr^2h

V=π(3)^2(11)

V=99π

This is about 311.02

Now find the volume of the salsa remaining

V=V=π(3)^2(5)

V=45π

Probability of blue is 0.4 red 0.3 yellow 0.3 there are 30 blue cubes in box what total number of cubes in box

Answers

Answer:

Step-by-step explanation:

The computation of the total number of cubes in box is shown below:

Given that

The probability of blue = 0.4

For red it is 0.3

And, for yellow it is 0.3

As if there is 30 blue cubes in a box

So for red it is = 30 × 0.3 ÷ 0.4 = 22.5

And, for yellow = 30 × 0.3 ÷ 0.4 = 22.5

Now the total number of cubes in a box is

= 30 + 22.5 + 22.5

= 75

Then the conquistadores, few in number but courageous, conquered the Amerindian civilizations, which, for all their temples and gold, were evidently no more than paper tigers. . . . British, French, Dutch, and other European soldiers, merchants, and settlers did much the same thing in those parts of the New World not yet claimed by the Iberians. The history of the New World subsequently became the struggle of European imperialist powers for domination, and Amerindians ceased to be important. . . .[A new generation of historians, however, took] a fresh look at the origins of European imperialism, [examining] perhaps elements less dramatic than gold and God and heroes. . . . [According to these historians], in 1492 two systems, one of the Old World and the other of the New World, collided. The Old World peoples had some distinct advantages in the biological competition that followed. . . . The decisive advantage of the [European] invaders of America was not their plants or animalsand certainly not their muskets and rifles, which Amerindians eventually obtained in quantitybut their diseases. . . .
