two times a number less 4 is greater than the same number plus 6. for what number or numbers is true?
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
7th grade math and serface area
Answer:
108 square yards
Step-by-step explanation:
l = 6 yd
w = 4 yd
h = 3 yd
Surface area of rectangular prism = 2*(lw +wh + hl)
= 2*(6*4 + 4*3 + 3*6)
= 2* ( 24 + 12 + 18)
= 2 *54
= 108 square yards
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.
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 expression represents the surface area of the prism?
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

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.
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.

The amount that will be withheld from his paycheck for income tax in all is d. $189.42.
What is the amount withheld?The amount withheld is a credit against the income taxes the employee must pay during the year.
The amount withheld from his paycheck for income tax in all is given by;
Amount withheld = State income tax + ( State income tax× Percentage of federal income tax)
Where:
State income tax=$154.00
Percentage of federal income tax=23%
Substitute all the values in the formula
Amount withheld=$154.00+($154,00×23%)
Amount withheld=$154.00+$35.42
Amount withheld=$189.42
Hence, the amount that will be withheld from his paycheck for income tax in all is d. $189.42.

the sum of two consecutive integers is 23. what are the numbers?
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.

Answer:
Each angle has a measure of 75 degrees
Step-by-step explanation:
First of all, we know that angle Z has a measure of 120 degrees and that angle W is a right angle. This means that the measure of angle W would have to be 90.
Next, we know that because the shape is a quadrilateral, the sum of its interior angles has to be equal to 360. Since we know that the measure of angles X and Y are equal (by definition of congruent), we will label them both with the variable x. We can then say the following:
2x + 90 + 120 = 360
We can then proceed to simplify this:
2x + 210 = 360
2x = 150
x = 75
So, the measure of x and y are 75.
For what values of x is x2 2x = 24 true? –6 and –4 –4 and 6 4 and –6 6 and 4
The value of the x of the equation x² + 2x = 24 is negative 6 and 4, then the correct option is C.
What is a factorization?It is the method to separate the polynomial into parts and the parts will be in multiplication. And the value of the polynomial at this point will be zero.
The expression equation is given below.
x² + 2x = 24
x² + 2x – 24 = 0
On factorization, we have
x² + 2x – 24 = 0
x² + 6x – 4x – 24 = 0
(x – 4)(x + 6) = 0
x = –6, 4
The value of x is –6 and 4.

Answer:
73 m

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
