Mrs. Kelley asked her students to plot the number of books they read over the summer.

A dot blot titled Books Read Over the Summer goes from 0 to 7. 0 has 1 dot, 1 has 3 dots, 2 has 6 dots, 3 has 2 dots, 4 has 3 dots, 5 has 1 dot, 6 has 2 dots, and 7 has 0 dots.

Using the dot plot, how many students answered the question?

Answer:

d.21

Step-by-step explanation:

840/40=21

Answer:

21 Weeks

Step-by-step explanation:

$840 ÷ 4 weeks = 21

You can also reverse work this by multiplying $40 by the other choices!

$40 x 40 = $1600

$40 x 35 = $1400

$40 x 32 = $1280

$40 x 21 = $840

As we can see, D is the only answer that makes sense, therefore 21 weeks is the answer.

Answer:

75.4

Step-by-step explanation:

v = pi * r^2 * h

v = 3.14 * 4 * 6

v= 3.14 * 24

v= 75.36 m^3

to the nearest tenth is 75.4 m^3

Answer

i know right

Step-by-step explanation:

Answer:

No.

Step-by-step explanation:

Use a vertical line test.

Vertical line test: If you can draw a vertical line and it does not cross two points in the line, then it is a function.

So, we draw a line.

Draw it through 9,0

It intercepts two points so No. This is not a function.

Hope this helps plz hit the crown :D

Answer:

[tex]\begin{array}{| c | c |}\cline{1-2} x & y\\\cline{1-2} -3 & 0\\\cline{1-2} -2 & 1\\\cline{1-2} -1 & 2\\\cline{1-2} 0 & 3\\\cline{1-2} 1 & 4\\\cline{1-2} 2 & 5\\\cline{1-2}\end{array}[/tex]

non-proportional

Step-by-step explanation:

Given equation:

[tex]y=x+3[/tex]

Create a table of ordered pairs using the given equation:

[tex]\begin{array}{| c | c | c |}\cline{1-3} x & x+3 & y\\\cline{1-3} -3 & -3+3 & 0\\\cline{1-3} -2 & -2+3 & 1\\\cline{1-3} -1 & -1+3 & 2\\\cline{1-3} 0 & 0+3 & 3\\\cline{1-3} 1 & 1+3 & 4\\\cline{1-3} 2 & 2+3 & 5\\\cline{1-3}\end{array} \implies \begin{array}{| c | c |}\cline{1-2} x & y\\\cline{1-2} -3 & 0\\\cline{1-2} -2 & 1\\\cline{1-2} -1 & 2\\\cline{1-2} 0 & 3\\\cline{1-2} 1 & 4\\\cline{1-2} 2 & 5\\\cline{1-2}\end{array}[/tex]

Graph

As the given equation is linear, plot two of the ordered pairs and draw a straight line through them.  (See attachment).

Proportional Relationship

A relationship in which two quantities vary directly with each other.

y varies directly as x:

[tex]y=kx[/tex]

(where k is some constant)

To find if the relationship is proportional using the table, find the ratio  [tex]\dfrac{y}{x}[/tex] of each row. If the ratio is the same, the relationship is proportional.

[tex]\begin{array}{| c | c | c |}\cline{1-3} x & y & \dfrac{y}{x}\\\cline{1-3} -3 & 0 & 0\\\cline{1-3} -2 & 1 & -0.5} \\\cline{1-3} -1 & 2 & -2 \\\cline{1-3} 0 & 3 & \text{-}\\\cline{1-3} 1 & 4 & 4\\\cline{1-3} 2 & 5 & 2.5\\\cline{1-3}\end{array}[/tex]

Graphs of proportional relationships pass through the origin (0, 0).

Therefore, the relationship is non-proportional because:

Step-by-step explanation:

The formula for area of a rectangle is A= length times width. They gave you the area of the entire rectangle. But because this is a shape with a cutout, you still need the area of the missing section.

A= 1*4 = 4 units

Now subtract that from 49.

A=49 - 4= 45 square units

Answer:

49-4 = 45

Answer:

[tex]\$1.75[/tex]

Step-by-step explanation:

Total amount paid for the nuts is $19.60

Total amount paid for the ribbons is $11.20

Profit made on each jar is 98￠= $0.98

Cost price of the nuts and ribbon for the 40 jars is [tex]19.6+11.2=\$30.8[/tex]

Cost price for nuts and ribbonn for one jar = [tex]\dfrac{30.8}{40}=\$0.77[/tex]

Selling price is the sum of the cost price and profit.

Selling price for one jar = [tex]0.77+0.98=\$1.75[/tex]

They charged [tex]\$1.75[/tex] for each jar.

Answer:

9

Step-by-step explanation:

From the question,

We are to evaluate the expression : 2a + b - 3 when a=5 and b=2.

We substitute 5 for a and 2 for b in the given expression

2a + b - 3

= 2(5) + 2 - 3

= 10 + 2 - 3

= 12 - 3

= 9

Answer:

x = -8

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Equality Properties

Step-by-step explanation:

Step 1: Define Equation

x + 5 = -3

Step 2: Solve for x

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Here we see that -3 does indeed equal -3.

∴ x = -8 is the solution to the equation.

Answer:

[tex]x=-8[/tex]

Step-by-step explanation:

Subtract 5 from both sides.

[tex]x=-3-5[/tex]

Simplify [tex]-3 -5[/tex] to [tex]-8[/tex]

[tex]x=-8[/tex]

let check if the answer is correct

[tex]x+5=-3[/tex]

Let [tex]x=-8[/tex]

[tex]-8+5=-3[/tex]

Simplify [tex]-8+5[/tex] to [tex]-3[/tex]

[tex]-3=-3[/tex]
