Answer:
b = 8
Step-by-step explanation:
-2 + 8(b + 3) = 86
Open the parenthesis
-2 + 8b + 24 = 86
Combine like terms
8b + 22 = 86
Subtract 22 from both sides of the equation
8b = 64
Divide both sides by 8
b = 8
The bases of the prism below are right triangles. The volume of the prism is 360
units. Find the height of the prism.
Answer:
15
Step-by-step explanation:
The surface of one of the triangles making the base of the prism is [tex]\frac 12 \cdot 6 \cdot 8 = 24[/tex].
At this point we can express the volume in terms of base surface and height as in [tex]360 = 24\cdot h[/tex] from which we can get the height by dividing by 24 both sides:
[tex]h= \frac{360}{24} = 15[/tex]
Mrs. Lovejoy makes flower arrangements. She has 36 red carnations, 60 white carnations, and 72 pink carnations. Each arrangement must have the same number of each color. What is the greatest number of arrangements she can make if she uses every carnation?
Answer:
12 arrangements
Step-by-step explanation:
We solve this question using the Greatest Common Factor method.
We are told that:
She has 36 red carnations, 60 white carnations, and 72 pink carnations.
The same number of each item should be in each basket.
The greatest number of baskets is calculated as follows:
Step 1
The factors of 36 are: 1, 2, 3, 4, 6, 9, 12, 18, 36
The factors of 60 are: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60
The factors of 72 are: 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72
Step 2
We Identify the number that is greatest and common amongst 36,60, and 72
This is 12.
Then the greatest common factor is 12
Therefore, the greatest number of arrangements she can make if she uses every carnation is 12 arrangements

Step-by-step explanation:
Can someone please help me figure out what’s 18 3/4 as a decimal
Solution:
We know that:
Given fraction: [tex]18\frac{3}{4}[/tex]Since the denominator is divisible by 100, we can solve this using an alternate way.
Step-1: Let's convert the mixed fraction into improper fraction.
Converting the mixed fraction to improper fraction:
[tex]18\frac{3}{4} \\\\= \frac{(18 \times4) + 3}{4} \\\\= \frac{72 + 3}{4} \\\\= \frac{75}{4}[/tex]
Step-2: Somehow, let's change the denominator to a 100.
Changing the denominator to a 100 using a proportion:
[tex]\frac{75x}{4x} = \frac{75x}{100} \\\\ 4x = 100 \\\\ x = 25 \\\\ \bold{Check:} \\\\\frac{75 \times25}{4 \times 25} = \frac{75 \times 25}{100} \\\\ \frac{1875}{100} = \frac{1875}{100} \bold{(True)}[/tex]
Step-3: Adjust the decimal to the right place.
Adjusting the decimal to the right place:
[tex]\frac{1875}{100} = 1875 \div 100 = 18.75[/tex]
Since 100 has 2 zeros, the decimal shifted 2 places to the left.
Thus, [tex]18\frac{3}{4}[/tex] in decimal form is [tex]18.75[/tex].
In decimal, mixed number [tex]18\dfrac{ 3}{4}[/tex] Can be written as 18.75.
To convert the mixed number [tex]18\dfrac{ 3}{4}[/tex] to a decimal, we can first convert the fraction part [tex]\dfrac {3}{4}[/tex] To its decimal equivalent, and then add it to the whole number part 18.
To convert 3/4 to a decimal:
Divide the numerator (3) by the denominator (4):
3 ÷ 4 = 0.75.
The fraction 3/4 is equivalent to 0.75 as a decimal.
Next, add the decimal equivalent of the fraction (0.75) to the whole number (18):
18 + 0.75 = 18.75.
Therefore, [tex]18\dfrac{ 3}{4}[/tex] As a decimal, is 18.75.

What are coordinates of points A, B, C, and D?
Answer:
See below.
Step-by-step explanation:
A = (-2/3, 0)
B = (-1/6, 0)
C = (1/2, 0)
D = (4/3, 0)
Step-by-step explanation:
the interval between 0 and 1 shows us, that on that scale the distance between 2 full numbers is split into 6 parts.
so, every little marker represents 1/6.
A goes 4 markers below 0 (left of 0) and is -4/6 = -2/3.
B goes 1 marker below 0 and is -1/6.
C goes 3 markers above 0 (right of 0) and is 3/6 = 1/2.
D goes 2 markers above 1 and is
1 + 2/6 = 6/6 + 2/6 = 8/6 = 4/3 = 1 1/3
please pick the format your teacher wants you to use to write the result.
if you actually need decimals instead of fractions :
-2/3 = -0.666666666...
-1/6 = -0.166666666...

Answer:
X Greater-than-or-equal-to 12 A closed circle is used on the graph. The arrow on the graph points right.Step-by-step explanation:
This one-step inequality can be solved by adding the opposite of the constant that is added to x. A number line graph of the solution is attached.
x -2.6 ≥ 9.4
x ≥ 12.0 . . . . . . add 2.6 to both sides
The "greater than" relation means that numbers larger than 12 will be included in the solution set. Shading of the number line will be to the right of 12.
The "or equal to" relation means that 12 itself is included in the solution set. This is indicated by a closed circle at 12 on the graph.

You are adding orange juice to a 10-liter capacity jar. The equation 3x – 2y = -5 relates the amount of juice y, in liters, with the number of minutes, x, you add juice. How much juice was in the jar to start?
At what rate is the jar filled?
Answer: 5/2 liters (or 2.5 liters) of juice were in the jar to start.
The jar was filled at a rate of 5 minutes.
Step-by-step explanation: Firstly, rearrange the equation so that y = mx + b. If you move the x over, you get -2y = -3x -5. To get rid of the -2 in front of the y, divide both sides by -2. Then you get y = 3/2x + 5/2.
The amount of juice in the jar initially is b, also known as the y-intercept.
If you look at the equation, you see that 5/2 is our y-intercept which means the jar initially had 5/2 liters of juice at the start (this is the same as 2.5 liters because 5 divided by 2 is 2.5).
To find the rate at which the jar was filled, you need to solve for x. Plug in the 10 liters for the y and solve.
y = 3/2x + 5/2
10 = 3/2x + 5/2
Now, subtract 5/2 from both sides.
7.5 = 3/2x
Divided both sides by 3/2 to get x alone, which will give you the number of minutes in which the jar was filled.
5 = x
The jar was filled at a rate of 5 minutes.

If a polygon has four right angles, then it is either a square or a rectangle.
Answer:
No because squares and rectangles are a type of polygon.
Step-by-step explanation:
A polygon is any shape with straight sides.
Polygon of having four right angles, then it is either a square or a rectangle.
What is polygon?A polygon is a closed object made of line segments rather than curves on a two-dimensional plane. Combining the terms poly, which means multiple, and gon, which means sides, creates the word polygon.
Given that,
A polygon has four right angles.
Since, A polygon of four right angles, then there will be four sides of polygon.
Four sides which are right angle can frame either a square or a rectangle.
A polygon is either a square or a rectangle.
This condition is true, because if all sides of polygon are equal then it will be a square and if all sides are not equal, then it will be a rectangle.
So, polygon with four right angles is either square or rectangle.
