There are 20 books in 4 boxes. How many books are there in 1 box?
Answer:
There are 5 books in 1 box
Step-by-step explanation:
It is quite easy to solve. You have to use division to figure out how many books go in each box. Our division equation will be: 20 ÷ 4 = ?
We will divide 20 by 4 and our answer is 5.
We can double-check our answer by doing multiplication. 5 x 4 = 20, leading us back to the original 20 books that are in boxes.
So, there are 5 books in each box.

Barbie spent $166 on clothes. She bought some shirts that cost $14 each and some pants that cost $22 each. She bought a total of 9 items. Select the system of equations to determine how many shirts and pants Barbie purchased. Let x represent the number of shirts and y represent the number of pants.
x + y = 166
14x + 22y = 9
x + y = 166, , 14x + 22y = 9,
x + y = 9
22x + 14y = 166
x + y = 9, , 22x + 14y = 166,
x + y = 9
14x + 22y = 166
x + y = 9, , 14x + 22y = 166,
x + y = 36
166x + 9y=14x + 22y
The correct system of equations will be;
⇒ x + y = 9
And, $14x + $22y = $166
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Barbie spent $166 on clothes.
The cost of each pant = $22
The cost of each shirt = $14
Total number of items = 9
Now,
Let number of shirts = x
And, The number of pants = y
Since, Total number of items = 9
So, we can formulate;
⇒ x + y = 9
And, The cost of each pant = $22
The cost of each shirt = $14
So, We can formulate;
⇒ $14x + $22y = $166
Therefore, The correct system of equations will be;
⇒ x + y = 9
And, $14x + $22y = $166

The patio shown has an area of 116 square feet. What is the value of h?
Answer:
8 ft
Step-by-step explanation:
if we made this into a rectangle (pretend you chop off one of the triangles and glue it to the other one to make a long rectangle), the length would be 10+4.5, or 14.5. to find what h is, we can just divide 116 by 14.5. our answer is 8.

Rashid can do a piece of work in 8 days, which Tipu can finish in 12 days. If they work at it on alternate days with Rashid beginning, in how many days, the work will be finished?
Answer:
The work will be finished in 10 days.
Step-by-step explanation:
Rashid can do a piece of work in 8 days
This means that each day he works, Rashid does [tex]\frac{1}{8}[/tex] of the work.
Tipu can finish in 12 days.
This means that each day he works, Tipu does [tex]\frac{1}{12}[/tex] of the work.
Each 2 days:
Each 2 days they work, the amount done is given by:
[tex]\frac{1}{8} + \frac{1}{12} = \frac{3 + 2}{24} = \frac{5}{24}[/tex]
Each 2 days, 5/24 of the work is done:
The number of periods of 2 days that is needed to finish the work(100% = 1 completed), is given by:
[tex]d = \frac{1}{\frac{5}{24}} = \frac{24}{5} = 4.8[/tex]
2*4.8 = 9.6
Rounding up
The work will be finished in 10 days.
Convert the following Logarithmic Equation into a Exponential Equation.
log_3(-2x+1)=-2y+6
Answer:
The conversion is given by [tex]3^{-2y+6} = -2x+1[/tex].
Step-by-step explanation:
Logarithmic Equation to Exponential Equation:
To realize the conversion of a logarithmic equation to an exponential equation, we need to understand the meaning of a logarithim. We have that:
[tex]\log_{a} b = c[/tex]
Means that:
[tex]b = a^c[/tex]
We are given the following equation:
[tex]\log_{3} (-2x+1) = -2y + 6[/tex]
It means that
[tex]3^{-2y+6} = -2x+1[/tex]
Which is the conversion.

Answer:

Step-by-step explanation:
I am assuming the question is asking which x value plugged into the function will give you a zero so
(-1)3 -8(-1)2 -23(-1)+30
so that simplyfiys to -1-8(1)+23+30
so that is -1-8+53
so -9+53
= 44
trying 3 we get
(3)3-8(3)2-23(3)+30
so that is 27 -72-69+30
and that is not zero
trying -10
we get
(-10)3-8(-10)2-23(-10)+30
which is -1000- 800+230+30
that is not zero so lastly trying 1 we get
(1)3-8(1)2-23(1)+30
which is 1-8-23+30
which is -7+7 which is zero

How does the function represented in the table change over equal intervals? What
does this tell you about the type of function it is?
For equal intervals changing in the independent variable, the corresponding dependent value does not change by equal differences, so it is not linear. which is the correct answer would be option (B).
What is the Linear function?A linear function is defined as an equation in which the highest exponent of the variable is always one.
The table is given in the question.
As per the given table,
The rate of change will be
During the first interval : (20-10)/(9-7) = 10/2
During the second interval : (30-20)/(11-9) = 10/2
During the third interval : (40-30)/(14-11) = 10/3
The corresponding dependent value does not vary by equal differences when equal intervals in the independent variable change, therefore it is not linear.
Hence, the correct answer would be an option (B).
