Solve for n: 21 K - 3n + 9 p is greater than 3 p + 12
Answer:
n > p + 1 + 7k
Step-by-step explanation:
21k - 3n + 9 > 3p + 12
21k - 3n > 3p + 12 - 9
3n > 3p + 3
3n > 3p + 3 + 21k
n > (3p + 3 + 21k)/3
n > p + 1 + 7k

A man drove 250 miles in 2.5 hours. If the posted speed limit was 75 mph the entire way how many miles per hour over the speed limit was he going?
A. 10 mph
B. 50 mph
C. 25 mph
D. 78 mph
Answer:
C. 25 mph
Step-by-step explanation:
First, find his speed in miles per hour:
250/2.5
= 100
This means he was going 100 mph
To find how much he was going over, subtract 75 from this
100 - 75
= 25
So, he was going 25 mph over the speed limit
The correct answer is C, 25 mph

Find the measure of the missing angles.
Answer:
angles b and c should be 153° each.
Step-by-step explanation:
We know the smaller angle is 27°. The other small angle, vertical to the 27° angle is also 27° because they are vertical angles. Along the lines, two angles should form 180°. So 180-27=153°. All together the angles should be 360°. Check your answer by doing 153+153+27+27=360. therefore the missing angles are both 153°
Triangle A is a scaled version of triangle B. The dimensions of triangle B are twice the dimensions of triangle A. The area of
triangle B is 144 sq cm.
What is the area of triangle A?
Answer:
576 sq cm
Step-by-step explanation:
For example imagine a rectangle, the area of which is width * height = area
If you multiply the dimensions by 2 you multiply the width AND the height which is 2 * width * 2 * height = 4 * width * height
This is true for all scalings, if you times the dimensions by n, you times the area by n^2
144 * 2^2 = 576

The number of people (n) who will attend a dance depends on the admission
price (p), in dollars. This relationship is represented by the equation shown below.
n = 800 - 50p
Show how to solve
Answer:
Step-by-step explanation:
B
The 50 fewer people will attend for every dollar the admission price increases option (b) is the correct interpretation of the slope of this equation.
What is a linear equation?It is defined as the relation between two variables if we plot the graph of the linear equation we will get a straight line.
If in the linear equation one variable is present then the equation is known as the linear equation in one variable.
The number of people (n) who will attend a dance depends on the admission price (p), in dollars. This relationship is represented by the equation shown below:
n = 800 - 50p
The above equation represents the linear equation and the slope of the equation:
m = -50
As we can see the price increases the number of attendants decreases because the slope of the line is negative.
Thus, the 50 fewer people will attend for every dollar the admission price increases option (b) is the correct interpretation of the slope of this equation.

Answer:
33 units²
Step-by-step explanation:
From the net, we can see that the surface area consists of four triangles and one square:
Surface area = 4(area of triangle) + (area of square)
The base of the triangles (b) = 3, and their perpendicular height (h) = 4.
Area of triangle = (1/2)bh
Area of triangle = (1/2)(3)(4)
Area of triangle = 6
The square has side length (L) 3.
Area of square = L²
Area of square = 3²
Area of square = 9
Surface area = 4(area of triangle) + (area of square)
Surface area = 4(6) + (9)
Surface area = 24 + 9
Surface area = 33
A square has a perimeter of 16.4 inches. The
area of the square is
square inches.
Answer:
area = 8.2 sq inch
Step-by-step explanation:
Answer:
The area of square is 16.81 in².
Step-by-step explanation:
Solution :
Firstly, finding the length of side of square by substituting the values in the formula :
[tex] \begin{gathered} \qquad{\twoheadrightarrow{\sf{Perimeter_{(Square)} = 4 \times Side}}} \\ \\ \quad{\twoheadrightarrow{\sf{16.4 = 4 \times Side}}} \\ \\ \quad{\twoheadrightarrow{\sf{Side = \dfrac{16.4}{4}}}} \\ \\ \quad{\twoheadrightarrow{\sf{\underline{\underline{Side = 4.1 \: in}}}}}\end{gathered}[/tex]
Hence, the length of side of square is 4.1 in.
[tex]\begin{gathered}\end{gathered}[/tex]
Now, finding the area of square by substituting the values in the formula :
[tex] \begin{gathered} \qquad{\twoheadrightarrow{\sf{Area_{(Square)} ={(Side)}^{2}}}} \\ \\ \qquad{\twoheadrightarrow{\sf{Area_{(Square)} ={(4.1)}^{2}}}} \\ \\ \qquad{\twoheadrightarrow{\sf{Area_{(Square)} ={(4.1 \times 4.1)}}}} \\ \\ \quad{\twoheadrightarrow{\sf{\underline{\underline{Area = \: 16.81 \: {in}^{2}}}}}} \end{gathered}[/tex]
Hence, the area of square is 16.81 in².

If ANQZ - ACBK, find BK. *
O BK = 39
O BK = 16
O BK = 65
O BK = 27
9514 1404 393
Answer:
(c) BK = 65
Step-by-step explanation:
Corresponding sides are proportional in similar triangles, so ...
ZT/ZQ = KF/KB
27/(2x +7) = 45/(4x+1)
27(4x+1) = 45(2x +7) . . . cross-multiply
3(4x +1) = 5(2x +7) . . . . divide by 9
12x +3 = 10x +35 . . . . . eliminate parentheses
2x = 32 . . . . . . . . . . . . . subtract 10x+3
x = 16 . . . . . divide by 2
Then the length of BK is ...
BK = 4x+1 = 4·16 +1
BK = 65
is -660.3 an integer?
Answer:
no
Step-by-step explanation:
you cannot find this number on a number line. it needs to be a full number with no decimal to be an integer
Answer:
No, it is not.
Step-by-step explanation:
An integer is a number located as a whole number on a number line, or coordinate plane. Due to the fact that the .3 makes it slightly off of -660, it wouldn't be on a plotted point on a number line.

Answer:
5a + 5
Step-by-step explanation:
5(a+1)=
5xa + 5x1=
5a + 5
Answer:
5 (a + 1) = 5a + 5
Step-by-step explanation:
You only have to open the parenthesis to simplify this expression.
5 (a + 1)
You multiply 5 by a, and you get 5a.
You also multiply 5 by 1, and you get 5.
5a + 5
So, 5 (a + 1) = 5a + 5.

which binomial is a factor of 8x^2y^3-18y
Answer:
Please check the explanation.
Step-by-step explanation:
Given the expression
[tex]8x^2y^3-18y[/tex]
Apply exponent rule: [tex]a^{b+c}=a^ba^c[/tex]
[tex]8x^2y^3-18y=8yy^2-18y[/tex] ∵ [tex]x^2y^3=yy^2[/tex]
[tex]=4\cdot \:2yy^2+9\cdot \:2y[/tex]
Factor out common term 2y
[tex]=2y\left(4x^2y^2-9\right)[/tex]
We know that the Binomial is an expression that consists of two terms. Thus,
(4x²y²- 9) represents the binomial factor of [tex]8x^2y^3-18y[/tex]
We can further simplify by Factoring 4x²y² - 9: (2xy + 3) (2xy - 3)
[tex]=2y\left(2xy+3\right)\left(2xy-3\right)[/tex]
Here:
(2xy + 3) and (2xy -3) are the binomial factors of [tex]8x^2y^3-18y[/tex] as each of them consists of two terms.
