Answer: 5 with an open circle facing the right.

Step-by-step explanation:

First: you need to know the difference between closed and open circles. Closed means less than or equal to/ greater than or equal to while an open circle just means less than/ greater than.

Second: To know if it will be facing left or right is very simple. It is just if the number is increasing or decreasing in your problem. If increasing it goes right if decreasing it goes left. In this case, the number increases each day so it will face the right.

Third: To start the problem you subtract the number of shells she has already (34) by how many she needs (100) which is 66. then divide 66 by the number of seashells they get a day (12) which would give you 5.5

Fourth: I'm going to guess that you can't do decimals on the graph so all you have to do is put an open circle with the arrow facing the right meaning everything after this point, not including the number it is on.

Answer:

d  ≥  7

Step-by-step explanation:

A closed dot means you CAN use the number in the equality (greater than and equal to or less than and equal to). An OPEN dot means it's just greater than or less than, no equal to. Positive numbers GROW to the right so if the line is going that way it means greater than or greater than and equal to. The same is true for the left side. The left side makes numbers get SMALLER which means less than or less than and equal to. Your problem has a closed dot and an arrow to the right so the inequality is d  ≥  7.

Answer:

C

Step-by-step explanation:

A Pythagorean triple is a 3,4,5 triangle and when you simply multiply by 2 you get 6,8,10 which is also a Pythagorean triple.

Hope this helps!

Answer: it's wrong

Step-by-step explanation: because there are 6 sides of a die, so there is a 1/6 chance of getting any number between 1 and 6.

reason: this'll help you know how to turn it into a fraction.

Chosen possibility of an action    

over (or fraction bar)

total amount of possibilities

so now that you know why, now we find out the possibilities of  rolling an odd and even numbers between 1 and 6.

1, 3, 5 = 3/6 = 1/2

2, 4, 6 = 3/6 = 1/2

which means there is 1/2 chance of getting either an even or an odd. so they are incorrect because they are as likely as to not likely to be rolled on.

Answer: they are wrong

Step-by-step explanation:  there is 6 sides of a die, so there is a 1/6 percent chance and number between 1 and 6

1, 3, 5 = 3/6 = 1/2 = 50%

2, 4, 6 = 3/6 = 1/2+= 50%

Answer:

4 books

Step-by-step explanation:

Our problem here is:

[tex](3.95)3+8.95b=47.65[/tex]

So we have to find B, and that will be our answer (the number of books).

1. Simplify the expression

[tex]3.95\cdot 3+8.95x=47.65[/tex]

Combine like terms:

[tex]11.85+8.95x=47.65[/tex]

2. Group all constants on the right side of the equation

[tex]11.85+8.95x=47.65[/tex]

Subtract  from both sides:

[tex]11.85+8.95x-11.85=47.65-11.85[/tex]

Group like terms:

[tex]8.95x+11.85-11.85=47.65-11.85[/tex]

Simplify the arithmetic:

[tex]8.95x=47.65-11.85[/tex]

Simplify the arithmetic:

[tex]8.95x=35.8[/tex]

3. Isolate the x

[tex]8.95x=35.8[/tex]

Divide both sides by 8.95:

[tex]\frac{8.95x}{8.95}=\frac{35.8}{8.95}[/tex]

Simplify the arithmetic:

[tex]x=\frac{35.8}{8.95}[/tex]

Simplify the arithmetic:

[tex]x=4[/tex]

Answer:

2.25 Miles is how many miles Monica can walk in one hour.

Step-by-step explanation:

You take 3/2 which is 1.5 in decimal form then take the 2 out of 2/3 divide 1.5 by 2, you get 0.75 then you add 0.75 to 1.5 and you get 2.25 which is how many miles she walks in one hour.

Answer: 2550

Step-by-step explanation:

it literally says it in the question

Answer: 108 ft³ 

Step-by-step explanation:

V= 4/3πr³ 

Facts:

Pi= 3

Diameter = 6

Step1; find the radius

Diameter is the length acaross the whole circle, but the radius is just 1/2 the circle. Therefore, if the diameter is 6, then the radius can be found by finding 1/2 of 6.

1/2 of 6= 1/2x6= 3.

R= 3

Step 2:  Plug in the numbers (into the formula)

PEMDAS

(exponents go first)

(then multiply from left to right)

V= 4/3πr³ 

V= 4/3x3x3³ 

V= 4/3x3x (3x3x3)

V= 4/3x3x27

V= (4/3x3)  x 27

V= 12/3x27

V= 4x27

V= 108

Volume= 108 ft³

Answer:

Parallel lines are lines that never meet and are always the same distance apart. Lines X, Y, and Z are all parallel to each other.

Step-by-step explanation:

Answer:

BE

Step-by-step explanation:

This is because it is the part of a line that has two endpoints and is finite in length.

Answer:

∠YDC = 140°

∠FAB = 75°

Step-by-step explanation:

17)
The equation

[tex]13x-3=55+3x+2[/tex]

[tex]13x-3x=55+2+3[/tex]

[tex]10x=60\\x=60/10=6[/tex]

∠FAB = 13(6) - 3 = 78 - 3 = 75°

18)

The equation

[tex]15x+5=80+6x+6[/tex]

[tex]15x-6x=80+6-5[/tex]

[tex]9x=81\\x=81/9=9[/tex]

∠YDC = 15(9)+5 = 135 + 5 = 140°

Hope this helps

Answer:

It is an acute triangle.

Two sides have the same length.

The third angle measures 70°.

Step-by-step explanation:

It is an acute triangle because all triangles are less than 90°.

Two sides have the same length because since we know that two angles, which would be the base angles are the same, then triangle must be isosceles.

180°-(40°+70°)= 110°

The x value is the same, the y value is different,

Y is the up and down movement.

Moving from -8 to -5 is an upward move of 3 units.

Answer: 1, 3 units up.

Answer: 30 inches = 2 1/2 feet

Step-by-step explanation:

30 inches is longer than 2 feet

Answer:

1,256 dm^2 and 400π dm^2

Step-by-step explanation:

The circumference is equal to 2pi times the radius. So 40pi=2pi times the radius so the radius is 20. The area of a circle is pi times the radius squared or 400pi and if using 3.14 for pi this would be 1,256 dm^2

Answer:

Step-by-step explanation:

Because the length width and height of the inch cube are all the same, 1/2 plus 1/2 is 1 so 8 cubes 2 for the length, height and width

as for the cubes volume, 1/2* 1/2* 1/2 = 1/8^3

amd the last ones u solve with the answers to the first 2,

8 Cubes * 1/8^3 = 1inch^3

Hope this helped have a good day

Answer:

(6, 10)

Step-by-step explanation:

Step 1: Substitute 2x-2 for ‘y’ in the first equation:

4x - (2x - 2)= 10

Step 2: Combine like terms

2x -2 =10

Step 3: Add 2 to both sides of the equation

2x = 12

Step 4: Divide both sides by 2

x= 6

Now substitute x=6 into any of the equations given, I chose the bottom one.

Step 5: Plug in x=6 and solve

y= 2(6) -2

y= 12-2

y= 10

Step 6: Write your answer as an ordered pair (x, y).

(6, 10)

Answer:

Isosceles

Step-by-step explanation:

Can't be square or rect.

Common sense, they have 4 points

Is an Isosceles triangle because it has 2 equal sides

Answer:

Explanation:

[tex]\rightarrow 3x(2x +4) -5(x^2 - 2x)[/tex]

[tex]\rightarrow 6x^2 +12x -5x^2 + 10x[/tex]

[tex]\rightarrow 6x^2 -5x^2+12x + 10x[/tex]

[tex]\rightarrow x^2 +22x[/tex]

As the above polynomial has two terms and highest power of 2, the polynomial is a Quadratic Binomial

Answer:

-400 meters below sea level

Step-by-step explanation:

740(1.5) +y=710

740 (1.5)+ 710

1010 + y =710

y= 710 -1110

so y is -400

Answer:

The answer would be C.

Step-by-step explanation:

We can tell that it has been translated, meaning that the answer will either be C or D. A reflection across the x axis would already reflect PQR six units left, meaning the answer would be C. Sorry for the bad explanation I'm really tired, I hope this helps! :)

Step-by-step explanation:

Answer: P= 2640 dam

or 264 hm

or 26.4 km

Step-by-step explanation:

See picture of all side values in the three measurement forms

Answer: I think this is right but I'm not 100 percent sure

26.4 km, 264 hm, 2640 dam

Step-by-step explanation:

Well, permitter is adding all lengths together.

Which is 5 km + 62 hm + 62 hm + 900 dm

Assuming hm stands for Hectometer, I will divide 62/10 = 6.2

Now we are left with the equation 5 km + 6.2 km + 6.2 km + 900 dam

Since 100 dm = 1 km, we will divide 900 dm by 100 which is 9 km

Lastly, we are left of with:

5 + 6.2 + 6.2 + 9 = 26.4 km

Now I will quickly covert everything into the other 2 measurements

26.4 km = 264 hm (10x)

26.4 km = 2640 dam (100x)
