The area of a rectangular field is 4526 m².
If the width of the field is 62 m, what is its length?
Answers
Answer:
73 m
Step-by-step explanation:
The formula for the area of a rectangle is a = w(l). Using this, we can plug in the given values and solve for l, the length.
4526 = 62(l)
[tex]\frac{4526}{62} =\frac{62l}{62}[/tex]
l = 73
hope this helps!
Answer: 73 meters
Step-by-step explanation:
The simple formula to calculate the area of a regular rectangle is (Length x Width)
Given the area is 4526, and the width 62, we can use "y" to represent the unknown length.
So, '
62(y)=4526
Divide both sides by 62
1/2[62(y)]=4526/62
Y= 73 meters.
To check, 73x62= 4526, which follows the formula
two times a number less 4 is greater than the same number plus 6. for what number or numbers is true?
Answers
Answer:
n > 10 meaning, n is greater than 10
Step-by-step explanation:
Two times a number : 2n
Less 4 : -4
2n-4
Greater than the same number : >n
Plus 6 : +6
> n+6
2n-4 > n+6
To find n, we have to get n alone and equal to a single number. To do this, we first subtract 6 from both sides.
2n-10 > n
Then, subtract 2n from both sides
-10 > -n
Now, divide by -1
10 < n
So, n is greater than 10
Which expression represents the surface area of the prism?
Answers
Answer:
A, 2 · 8 + 2 · 55 + 88
Step-by-step explanation:
If we find the area of the two triangles above and below, we know the area of one triangle is 8 because (formula for area of triangle: a = bh x 1/2, and a = 8(2) x 1/2 which equals 8). So if we double this area, we would get 2 · 8.
If we were to find the area of both the rectangles that are left and right of this figure, we know the area of one rectangle would be 55 because (formula for area of rectangle: a = l x w, and a = 5(11) would equal 55). So if we'd doubled this, we would get 2 · 55.
If we were to find the area of the rectangle in front of this entire figure, we know the area would be 88 because (formula for area of rectangle: a = l x w, and a = 11(8) which would equal 88).
So if we find the surface area of this figure, we'd just need to piece this together to form:-
2 · 8 + 2 · 55 + 88
Answer:
2 · 8 + 2 · 55 + 88

5x – 5 = 7x + 1 what is this question
Answers
Answer:
x = - 3
Step-by-step explanation:
5x - 5 = 7x + 1 ( subtract 7x from both sides )
- 2x - 5 = 1 ( add 5 to both sides )
- 2x = 6 ( divide both sides by - 2 )
x = - 3
Answer: x = -3
Step-by-step explanation: Here is my explanation...
Step 1: Take away 5x from both sides 5x - 5x - 5 = 7x - 5x + 1.
Step 2: You should then get -5 = 2x + 1, then take away 1 from both sides -5 - 1 = 2x + 1 - 1
Step 3: -6 = 2x, divide 2x on both sides -6/2 = 2x/2
x = -3
Work Check:
5 (-3) - 5 = 7 (-3) + 1
-15 - 5 = -21 + 1
-20 = -20
If the -20 = -20 then this proves that x = -3. I hope this helped!

What is the area of the composite figure? 262 cm2 264 cm2 266 cm2 268 cm2
Answers
The Area is a two-dimensional scalar quantity. The area of the composite figure is 264 cm².
What is the area?The area of a two-dimensional region, form, or planar lamina in the plane is the quantity that represents its extent. On the two-dimensional surface of a three-dimensional object, the surface area is its counterpart.
The composite figure can be broken down into four parts a square(A), a triangle(B) and two rectangles(C and D).
Now, if the area of the composite figure is taken out it will be,
[tex]\text{Area of composite}=\text{Area of Square A} + \text{Area of triangle B} + \text{Area of Rectangle C} + \text{Area of Rectangle D}\\[/tex]
[tex]\text{Area of Composte}=(10^2)+(\dfrac12 \times 6 \times 4)+(8 \times 4)+(20 \times 6)\\\\\text{Area of Composte}= 100+ 12 + 32 + 120 =264\rm\ cm^2[/tex]

Use the Distributive Property ⇒ x(a + b) = xa + xb7(x) + 7(3)7x + 21the sum of two consecutive integers is 23. what are the numbers?
Answers
Answer:
23
Step-by-step explanation:
the 1st number is x
because they are consecutive:
2nd number is (x+1)
now,
x+(x+1)= 23
2x=23–1
2x=22
x=22/2= 11
so two consecutive numbers are 11 & (11+1)=12
now 11+12=23
Answer:
11 and 12
Step-by-step explanation:
Let the integers be x and x + 1.
Sum of two consecutive integers is 23.
x + x + 1 = 23
2x + 1 = 23
2x = 23 - 1
2x = 22
x = 22 / 2
x = 11
x + 1
= 11 + 1
= 12
The numbers are 11 and 12.
Which statements must be true according to the histogram? check all that apply. the data is qualitative. the data is skewed right. there were 31 people at the party. there were children at the party. the most common age of the attendees was 13 years old. the majority of the people at the party were less than 61 years old.
Answers
The statements that must be true according to the data presented by the considered histogram are:
Option 2: the data is skewed right. Option 3: there were 31 people at the party.Option 6: the majority of the people at the party were less than 61 years old.How to identify skewed graph?A skewed distribution is a distribution having bias on one of the two sides (either left or right).
It is like leaning mountain on one side (left or right).
A left skewed graph have elongated tail on the left side of the main mountain like figure. The mountain like figure is after that elongated tail. It is also called negatively skewed graph.A right skewed graph has elongated tail on the right side of the main mountain like figure. The mountain like figure is before that elongated tail. It is also called positively skewed graph.The missing image of the considered histogram is attached below.
Checking all the options:
Option 1: the data is qualitative.It is wrong. The data is numeric, and therefore, not describing qualities, so its not a qualitative data.
Option 2: the data is skewed right.The histogram has long tail on the right side, so its right skewed. Thus, this option is correct.
Option 3: there were 31 people at the party.Age group Frequency (number of people of that age group in party)
0-20 5
21-40 13
41-60 8
61-80 3
81-100 2
total 5+13+8+3+2 =31
So yes, there were total 31 people at the party as a person can be at max in one age group, so no repeated counting.
Option 4: there were children at the party.From 0 to 20 age group, there were 5 people. But it isn't known if they were < 18 or ≥ 18 (this is the side effect of grouped data, the loss of some information). So this option is not necessarily correct.
Option 5: the most common age of the attendees was 13 years old.It is false. The most common age was from the group 21-40 years old. And 13 is < 20, so it doesn't lie in this group.
Option 6: the majority of the people at the party were less than 61 years old.
Total number of people < 61 = 5+13+8 = 26
26 is more than half of 31 people. So yes, this option is correct.
Thus, the statements that must be true according to the data presented by the considered histogram are:
Option 2: the data is skewed right. Option 3: there were 31 people at the party.Option 6: the majority of the people at the party were less than 61 years old.Learn more about skewed distribution here;

Which is the completely factored form of 4x2 28x 49? (x 7)(4x 7) 4(x 7)(x 7) (2x 7)(2x 7) 2(x 7)(x 7)
Answers
The completely factored form of 4x^2 + 28x + 49 is given by: Option C: (2x+7)(2x+7)
How to find the factors of a quadratic expression?If the given quadratic expression is of the form ax^2 + bx + c, then its factored form is obtained by two numbers alpha( α ) and beta( β) such that:
[tex]b = \alpha + \beta \\ ac =\alpha \times \beta[/tex]
Then writing b in terms of alpha and beta would help us getting common factors out.
Sometimes, it is not possible to find factors easily, so using the quadratic equation formula can help out without any trial and error.
For this case, the given quadratic expression is:
[tex]4x^2 + 28x + 49[/tex]
So we've to find two numbers such that:
Their sum = b = 28
Their product = [tex]ac = 4\times 49 = 196[/tex]
We can see that 196 is square of 14, and that 14 added twice forms 28, thus:
14 + 14 = 28
14×14 = 196
Writing b = 28 as sum of 14 twice, we get:
[tex]4x^2 + 28x + 49 = 4x^2 + 14x + 14x +49 \\4x^2 + 28x + 49 = 2x(2x+7) + 7(2x + 7)\\4x^2 + 28x + 49 = (2x+7)(2x+7)[/tex]
Thus, the completely factored form of 4x^2 + 28x + 49 is given by: Option C: (2x+7)(2x+7)

Brainlist A 12" diameter 1-topping pizza costs $8.99. A 14" diameter 1-topping pizza costs $10.99. Which pizza option
gives you more for your money? Justify your answer.
Answers
Answer:
The 14" diameter pizza gives you more pizza for your money since it costs less per square inch.
Step-by-step explanation:
We can find the price per square inch of each pizza.
area = πr²
12" diameter pizza
area = π × (6 in.)² = 36π in.²
cost per in.²: $8.99/(36π in.²) = 0.079 $/in.²
14" diameter pizza
area = π × (7 in.)² = 49π in.²
cost per in.²: $10.99/(49π in.²) = 0.071 $/in.²
The 14" diameter pizza gives you more pizza for your money since it costs less per square inch.
