Step-by-step explanation:
the area of a rectangular painting is 5346cm square. if the width of the painting is 66 centimeters what is its lenght
The area of a rectangle is length*width
Since we have the width, we can do 5346/66 to get the length
So the length is 81 cm
Hope this helped
Answer:
81 cm
Step-by-step explanation:
Area = Length × Width
5346cm² = length × 66cm
Length = 5346 ÷ 66
Length = 81cm

possible. Otherwise, approximate to the
nearest tenth.

(6) The value of [tex]\sqrt{64}[/tex] is 8.
(7) The value of [tex]-\sqrt{31}[/tex] is -5.6
(8) The value of [tex]-\sqrt{16}[/tex] is -4
Explanation:
(6) The expression is [tex]\sqrt{64}[/tex]
Since, 64 is a perfect square, this can be written as [tex]8 \times 8[/tex].
Thus, the expression can be written as
[tex]\sqrt{64}=\sqrt{8 \times 8}=\sqrt{8^{2} }[/tex]
The square root gets cancelled. Thus, we have,
[tex]\sqrt{64}=8[/tex]
Thus, the value of [tex]\sqrt{64}[/tex] is 8.
(7) The expression is [tex]-\sqrt{31}[/tex]
Since, 31 is not a perfect square and solving the expression using a calculator, we get,
[tex]-\sqrt{31}=-5.56776[/tex]
Rounding off to the nearest tenth, we get,
[tex]-\sqrt{31}=-5.6[/tex]
Thus, the value of [tex]-\sqrt{31}[/tex] is -5.6
(8) The expression is [tex]-\sqrt{16}[/tex]
Since, 16 is a perfect square, this can be written as [tex]4\times 4[/tex]
Thus, the expression can be written as
[tex]-\sqrt{16}=-\sqrt{4\times 4}=-\sqrt{4^{2} }[/tex]
The square root gets cancelled. Thus, we have,
[tex]-\sqrt{16}=-4[/tex]
Thus, the value of [tex]-\sqrt{16}[/tex] is -4.

Justin has $7.50 more than Eva ,and Emma has 12$ less than Justin. Together, they have a total of $63.00 How much money does each person have?
Eva has $20.00, Justin has $27.50 and Emma has $15.50
Step-by-step explanation:
The given is:
Justin has $7.50 more than EvaEmma has 12$ less than JustinTogether, they have a total of $63.00We need to find how much money each person has
Assume that Eva has $x
∵ Eva has $x
∵ Justin has $7.50 more than Eva
- Add 7.50 to x
∴ Justin has = x + 7.50
∵ Emma has $12 less than Justin
- Subtract 12 from (x + 7.50)
∴ Emma has = x + 7.50 - 12 = x - 4.50
∵ Together, they have a total of $63.00
- Add x , (x + 7.50) and (x -4.50), then equate the sum by 63.00
∴ x + (x + 7.50) + (x - 4.5) = 63.00
- Add like terms
∴ (x + x + x) + (7.5 - 4.5) = 63.00
∴ 3x + 3 = 63.00
- Subtract 3 from both sides
∴ 3x = 60.00
- Divide both sides by 3
∴ x = 20.00
Substitute x by 20.00 in each expression above
∴ Eva has = $20.00
∴ Justin has = 20.00 + 7.50 = $27.50
∴ Emma has = 20.00 - 4.50 = $15.50
Eva has $20.00, Justin has $27.50 and Emma has $15.50

Identical twins happen once
in 250 births. How many pairs
of these twins might be at a
school with 2,750 students?
Answer:
11
Step-by-step explanation:
if there are twins born every 250 births take your large number (2,750) and divide it by 250 to get your answer
There are 11 pairs of twins at a school with 2750 students.
What is division?Repetitive subtraction is the process of division. It is the multiplication operation's opposite. It is described as the process of creating equitable groups. When dividing numbers, we divide a larger number down into smaller ones such that the larger number obtained will be equal to the multiplication of the smaller numbers.
Given identical twins happen once in 250 births,
total number of students in school = 2,750
to find the pair of twins divide the total number of students by 250
= 2750/250 = 11
Hence there are 11 pairs of twins in 2,750 students.

what is the sum of 2/10 + 6/100
Answer:
26/100 which is simplified to 13/50
Step-by-step explanation:
you have to get equal denominators so multiply 2/10 by 10 on top and bottom to get 20/100 then you can add 6/100 plus 20/100 which is 26/100 . denominators stay the same 26/100 can be simplified to 13/50
The sum of 2/10 and 6/100 is 13/50.
To find the sum of 2/10 and 6/100, we'll first find a common denominator and then add the fractions together.
The common denominator for 10 and 100 is 100, as it is the smallest multiple that both denominators can evenly divide into.
Now, we'll rewrite both fractions with the common denominator of 100:
2/10 = (2/10) * (10/10) = 20/100
6/100 = 6/100
Now that both fractions have the same denominator, we can add them together:
20/100 + 6/100 = (20 + 6)/100 = 26/100
Now, we have the sum of the fractions as 26/100. To simplify this fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 2:
(26 ÷ 2) / (100 ÷ 2) = 13/50

Hours Spent at Water Park A 2-column table with 4 rows titled Hours Spent at Water Park. Column 1 is labeled Hours with entries 4, 5, 6, 7. Column 2 is labeled Tally with entries 4, 5, 3, 4. Write a statistical question that might have been asked to gather the data. Then explain why it is statistical.
Answer:
The question is: How much time do people spend in the water park?It is a statistical because the answer comes from a sample instead of from the entire population.
Explanation:
Rewrite the table
Hours Spent at Water Park
Hours Tally
4 4
5 5
6 3
7 4
These data could be the results of a survey whose target was to detemine how many hours people spent at a water park.
The size of the sample should be the number of tally, which is 4 + 5 + 3 + 4 = 16.
And the question most likely was made at the exit of a water park, when the people were leaving the park.
Thus, the statistical question could be How much time do people spend in the water park?
It is a statistical because the survey is made to a sample of the people who went to the water park instead to all the people. All the people who go to the water park is the population about whom you want to determine how much time they spend in the water park, but,since it is impossible to survey all the people, you need to survey a sample.
The resulting values from a sample are named statistical. The values for an entire population are named parameters. A statistical permits to draw conclusions for populations using just one or more samples, which should be random samples.
Answer:
sample responce
Step-by-step explanation:
“How many hours did you spend at the water park today?” It is statistical because the responses will vary among individuals and the responses will be numeric.

Answer:
Therefore (28,45,53) is a Pythagorean triple.
Step-by-step explanation:
A Pythagorean triple consists of three positive integers a,b and c such that
a²+b²=c²
1.
3²+6²=45 and 12²=144
∴3²+6²≠144
Therefore (3,6,12) is not a Pythagorean triple.
2.
8²+16²= 330 and 32²= 1024
∴8²+16²≠32²
Therefore (8,16,32) is not a Pythagorean triple.
3.
12²+34²=1024 and 34²=5611
∴12²+34²≠34²
Therefore (12,34,30) is not a Pythagorean triple.
4.
28²+45²=2809 and 53²=2809
∴28²+45²=53²
Therefore (28,45,53) is a Pythagorean triple.
What is the product? 3 x [1 -4 5 -7]
Answer:
A
Step-by-step explanation:
3,-12,15,-21
The product 3 x [1 -4 5 -7] of [ -3 12 -15 21 ]
In mathematics, when we multiply a scalar (a single number) by a vector, the result is a new vector where each element of the original vector is multiplied by that scalar.
In this case, we have the scalar 3 and the vector [1 -4 5 -7].
1. Multiply each element of the vector by the scalar 3:
3 x 1 = 3
3 x (-4) = -12
3 x 5 = 15
3 x (-7) = -21
2. Arrange the results in order:
-3 12 -15 21
So, the product of 3 and the vector [1 -4 5 -7] is the new vector [-3 12 -15 21].
In this process, we essentially scaled each component of the original vector by a factor of 3, either increasing or decreasing the magnitude based on the sign of the original component.

Choose a linear function for the line represented by the point-slope equation y-5= 3(x - 2).
f(x) = 3x + 1
f(x) = 3x - 1
f(x) = 8x + 10
f(x) = 8x – 10
f(x) = 3x - 1 is the linear function for the line represented by the point-slope equation
Solution:
Given point slope equation is:
[tex]y - 5 = 3(x-2)[/tex]
We have to find the linear function for the line
The formula y = mx + b is said to be a linear function
Rearrange the given equation
[tex]y - 5 = 3(x-2)\\\\y - 5 = 3x - 6\\\\Move\ the\ varibale\ y\ to\ one\ side\ and\ constants\ and\ x\ to\ other\ side\\\\y = 3x - 6 + 5\\\\y = 3x - 1[/tex]
Let y = f(x)
Then we get,
f(x) = 3x - 1
Thus the linear function is found
Answer:
the answer will be B. f(x)=3x-1
