A first number is four more than seven time a second. The sum of the number is 92. Find the number.
Answers
Answer:
11
81
Step-by-step explanation:
x = 7y + 4
x + y = 92
Solve for x in the second equation
x = 92 - y
92 - y = x
Equate the 2 xs
92 - y = 7y + 4 Add y to both sides
92 = 7y+y + 4 Combine
92 = 8y + 4 Subtract 4 from both sides
88 = 8y Divide by 8
88/8 = y
y = 11
===========
x = 7y + 4
x = 77 +4
x = 81

If the ratio of red to white is 2:10 then then there are 200 white cars.
Explanation:
15 divided by 3 is 5. So you multiply 8 by 5 to get 40. 40:15 reduces to 8:3.
With 40 red cars the ratio of 2:10 would be made into 40:200.
The fractions/ratios have to remain proportional.

The scale of a square map indicates that each inch on the map
corresponds to 5 miles. Write an expression that describes the area of
land shown on the map. If the map is 8 inches on one side, what is the
area of land shown on the map?
Answers
Answer:
Area of land: 800 miles.
Step-by-step explanation:
Since the map is a square, you can assume that all 4 sides will equal 8 inches. (Giving you a perimeter of 32, and an area of 64.) Since each inch corresponds to 5 miles, you multiply 8 by 5 which equals 40.

Which equation represents a line that passes through (0,–8) and (–5,–23)?
A) y = 4x – 8
B) y = –8x + 3
C) y = 5x – 8
D) y = 3x – 8
Answers
The equation of line that passes through points (0,-8) and (-5,-23) is y=3x-8 which is option d.
Given that the line passes through (0,-8) and (-5,-23).
We are required to find the equation of the line that passes through (0,-8) and (-5,-23).
Equation is like a relationship between two or more variables expressed in equal to form. Equation of two variables look like ax+by=c. It may be linear equation, quadratic equation, cubic equation, and many more depending on the power of the variable.
The formula to form the equation from two points is as under:
[tex](y-y_{1}) =(y_{2} -y_{1} )/(x_{2} -x_{1} ) * (x-x_{1} )[/tex] in which [tex](x_{1} ,y_{1} ),(x_{2} ,y_{2} )[/tex] are the points.
(y+8)=(-23+8/-5-0)(x-0)
y+8=(-15/-5) x
y+8=3x
y=3x-8
Hence the equation of line that passes through points (0,-8) and (-5,-23) is y=3x-8 which is option d.

The side length of the base of a square pyramid is 30 centimeters. The height of the pyramid is 45 centimeters.
What is the volume of the pyramid in cubic centimeters?
Answers
Answer:
volume = 13500 [tex]cm^{3}[/tex]
Step-by-step explanation:
For a given pyramid, its volume can be determined by:
volume of pyramid = [tex]\frac{lwh}{3}[/tex]
Where: l is the base length, w is the base width and h id the height of the pyramid.
For the given question, l 30 cm, w = 30 cm and h = 45 cm.
So that,
volume = [tex]\frac{30*30*45}{3}[/tex]
= [tex]\frac{40500}{3}[/tex]
= 13500
volume = 13500 [tex]cm^{3}[/tex]
The volume of the pyramid is 13500 [tex]cm^{3}[/tex].
The volume of the square-based pyramid is [tex]13500cm^3[/tex]
The volume of a pyramid is given by
[tex]V=\dfrac{Ah}{3}[/tex]
where
[tex]A=\text{area of the square base}\\h=\text{perpendicular height}[/tex]
The area of the square base, [tex]A[/tex], is calculated as follows
[tex]A=side^2\\=(30cm)^2\\=900cm^2[/tex]
substitute the value of [tex]A[/tex], and [tex]h[/tex] ([tex]45cm[/tex]) into the volume formula to calculate the pyramid's volume
[tex]V=\dfrac{Ah}{3}\\\\=\dfrac{900\times 45}{3}\\\\=13500cm^3[/tex]
Therefore, the volume of the pyramid is [tex]13500cm^3[/tex]
