Answer:
Step-by-step explanation:
Area of polygon = area of square + area of triangle
Square:
Side = 12 cm
Area of square = side *side
= 12 * 12
= 144 sq.cm
Triangle:
base (b) = 12 cm
Height h = 19 cm
\(Area =\frac{1}{2}bh\\\\=\frac{1}{2}*12*19\\\)
= 6 * 19
= 114 sq.cm
Area of polygon = 144 + 114 = 258 square cm

The solution to the equation is:
\(x=-5\)
Step-by-step explanation:
Step 1: Rearrange the equation
Since we have to solve the equation for \(x\), let's bring the \(\frac{x}{6}\) to the other side with all the other variables:
\(\frac{5x}{3}-x=\frac{x}{6}-\frac{5}{2}\\\\\text{Subtract}~\frac{x}{6}~\text{from both sides of the equation:}\\\frac{5x}{3}-x-\frac{x}{6}=\frac{x}{6}-\frac{x}{6}-\frac{5}{2}\\\\\text{Simplify:}\\\frac{5x}{3}-x-\frac{x}{6}=-\frac{5}{2}\)
Step 2: Make use of the distributive property
The property states that when there's an expression like \(3(2x+6)\), it can be written as \(3(2x)+3(6)\), or vice versa.
In the equation we have found above, the left hand side of the equation has a common variable: \(x\)
Using the principle of distributive property, we can arrange the left hand side differently:
\(\frac{5x}{3}-x-\frac{x}{6}=-\frac{5}{2}\\x(\frac{5}{3}-1-\frac{1}{6})=-\frac{5}{2}\)
We have arranged the left hand side as such, that distributive property is applicable for it.
Step 3: Solving
First, let's simplify the equation:
\(x(\frac{5}{3}-1-\frac{1}{6})=-\frac{5}{2}\\\\\text{Add the numbers inside the bracket:}\\x(\frac{1}{2})=-\frac{5}{2}\)
Now, let's solve it:
\(\frac{1}{2}x=-\frac{5}{2}\\\\\text{Multiply both sides of the equation by}~2:\\\frac{1}{2}x\times 2=-\frac{5}{2}\times 2\\\\\text{Calculate:}\\\frac{2}{2}x=-\frac{10}{2}\\x=-5\)

First we start with the formula for cylinders v=(pi)r(squared)h filled in Thats v=(3.14)(8 squared) (8) which brings us to the answer 1607.68 but you must round to the nearest tenth aka 1607.7
Answer:
The first option, V ≈ 1607.7 in²
Step-by-step explanation:
Find the volume of the given cylinder.
\(\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}\)
Given:
r = 8 in
h = 8 in
π = 3.14
Find:
V = ?? in³
\(\hrulefill\)
Now solving,
Substitute the given values into the formula:
=> V = (3.14)(8)²(8)
Using a calculator to simplify:
=> V = 1607.68 in²
Rounded to the nearest tenth:
∴ V ≈ 1607.7 in²
Thus, the first option is correct.
Solve -16x = -80. A. -64, B. -5, C. -96, D. 5
Answers
-16x= -80
x has to be a positive number in order to be multiplied by a negative number and still get a negative answer. Therefore D is the only correct option.
Answer:
B. -5
Step-by-step explanation:
-16x = -80
Divide both sides by -16, so that the x stands alone
(-16x) / (-16) = (-80) / (-16)
The two -16's cancel each other out on the left side
x = 80 / -16
So now all we have is 80 divided by -16, which we can simplify to
x = -5

Write the math sentence as an equation: Negative eight times the sum of a number and 14.5 is 64.5
−8(r − 14.5) = 64.5
−8r + 14.5 = 64.5
−8(r + 14.5) = 64.5
−8r − 14.5 = 64.5
Answers
Answer:
The correct equation is −8(r + 14.5) = 64.5
Step-by-step explanation:
This equation states that negative 8 times the sum of a number (r) and 14.5 is equal to 64.5.
The other equations are not correct because they do not correctly represent the given statement. In equation 1, the minus sign is in the wrong place, and in equation 3, the minus sign is missing before the 14.5. In equation 4, the minus sign is missing before the 8.
I hope this helps. Let me know if you have any further questions.
You start with -8, then to multiply it my a sum you need to put that addition equation in parentheses so -8(r+14.5), then we know the whole thing is equal to 64.5, so -8(r+14.5)=64.5
By process of elimination: We know A is not correct because it has a subtraction problem in the parenthesis, and we know it should be addition because of the key word “sum” with refers to an addition problem.
We know B is not correct because there are no parenthesis, and since we need to multiply -8 to the sum/total of the addition problem, it wouldn’t work without parenthesis.
We know D is not correct for the same reasons as A and B, there are no parenthesis and there is not addition sign
I’m knew to this, and I tried to simplify my answer so if you need any clarification let me know! Good luck!

Answers
Answer: Ok, fast. Here we go: Basically the number sequence increases by 3 every number. 7+3=10 10+3=13. Etc, etc.
Step-by-step explanation:
So just go from 19 (which is the 5th term) and count up.
19+3=22(6th term) 22+3=25(7th term) 25+3=28(8th term) 28+3=31(9th Term) 31+3=34(10th term)
34 is your answer.
a: We can quickly find the answer by multiplying 3 by 5, then by adding the quantity of the numbers to 19.
\(5(3) + 19\)
15 + 19 = 34
Therefore, the 10th term in this number sequence is 34.
b: n represents the numbered term of the number sequence.
3 can represent x in the expression we make.
\(3x = n\)
Therefore, a possible expression for this number sequence is 3x = n.
A restaurant serves you a 16-fluid ounce glass of juice that is 30% ice. How many fluid ounces of juice do you actually get? Show all of your work
Answers
to solve how much ice there is you need to do 16 • .30, which would get you 4.8
Now you need to subtract 4.8 from 16, since the 4.8 is the amount of ice in the glass of juice.
So you would actually get 11.2 ounces of juice.

D 1313
E 17
Answers
Answer:
Mean = 16
Step-by-step explanation:
MEAN can be find bg the sum of all score divided by the amount of the score.
Mean = total amount / number of amount
Total amount = 2 + 3 + 5 + 9 + 17+ 22 + 31 + 39
= 128
number of amount = 2, 3, 5, 9, 17, 22, 31, 39
= 8
Then we can calculate mean as
Mean = 128/8
Mean = 16
2+3+5+9+17+22+31+39=128
128/8=16

Banana Cupcakes
makes 10 cupcakes
1 cup granulated sugar
cup vegetable oil
1 large egg
4 tablespoons sour cream
2 medium-sized ripe bananas, mashed
1 cups all-purpose flour
1 teaspoon baking soda
teaspoon salt
1 teaspoon vanilla extract
pinch of nutmeg
You will use the recipe above to answer the following questions:
This recipe serves 10, but you need to serve 30. What number will you need to multiply the amount of each ingredient by to adjust the recipe? How did you determine this number?
How much vegetable oil do you need for 30 cupcakes?
How much flour do you need for 30 cupcakes?
What is the difference in the amount of vanilla extract you would need for 30 cupcakes?
What is the difference in the amount of salt you would need for 30 cupcakes?
In the real world, even though you make adjustments to a recipe to accommodate the number of people you need to serve, you sometimes round the amount of an ingredient instead of using an exact amount. Which ingredient would it make more sense to round rather than coming up with the exact amount? Why?
Answers
Answer: Hey give me 1 hour and ill answer it I'm doing odessyware rn so Ill get back to you later appreciate yo patients.
Step-by-step explanation:
Then, if we want to make 30 servings, we need to use that recipe 3 times. (because x*10 = 30, then x = 30/10 = 3)
This would be equivalent to multiply each ingredient by 3.
for 30 cupcakes we need:
3 cups of vegetable oil.
3 cups of all-purpose flour
(because for each one of these ingredients we needed only 1 cup to make 10 cupcakes).
for 10 cupcakes we need 1 teaspoon of vanilla.
for 30 cupcakes we need 3 teaspoons of vanilla, the difference is 3 - 1 = 2.
So the difference is 2 teaspoons.
About which quantities we should round are those where we may have mixed numbers or big numbers.
For example, we have 4 tablespoons of sour cream for 10 servings, then for 30 servings we should have:
3*4 = 12 tablespoons.
We could round this down to 10 tablespoons.
