The surface areas of two cubes have a ratio of 49to 81. What is the ratio of the edge lengths of the two cubes
Answer:it is 3 to 4
Step-by-step explanation:
This is correct
The ratio of the edge lengths of the two cubes is 7 : 9.
What is surface area of cube?The surface area of the cube can be defined as the total area covered by all six faces of the cube.
Given
The surface areas of two cubes have a ratio of 49 to 81.
Formula of surface area of cube = 6[tex]a^{2}[/tex]
Surface area of cube 1 = [tex]6a^{2} _{1}[/tex]
Surface area of cube 1 = [tex]6a^{2} _{2}[/tex]
Surface areas of two cubes have a ratio of 49 to 81.
[tex]\frac{6a^{2} _{1} }{6a^{2} _{2}}=\frac{49}{81}[/tex]
⇒ [tex]\frac{a^{2} _{1} }{a^{2} _{2}}=\frac{49}{81}[/tex]
⇒ [tex](\frac{a_{1} }{a_{2} } )^{2} =\frac{49}{81}[/tex]
⇒ [tex]\frac{a_{1} }{a_{2} } =\sqrt{\frac{49}{81} }[/tex]
⇒ [tex]\frac{a_{1} }{a_{2} } =\frac{7}{9} }[/tex]
⇒ [tex]a_{1}:a_{2} = 7:9[/tex]
Hence, the ratio of the edge lengths of the two cubes is 7 : 9.

On the map below, 14 inch represents one mile. Candler, Canton, and Oteen are three cities on the map.
Map_problem_figure_aff1d9be1f7b39bb6155b3bcf9b3ddd4
If the distance between the real towns of Candler and Canton is 9 miles, how far apart are Candler and Canton on the map?
If Candler and Oteen are 312 inches apart on the map, what is the actual distance between Candler and Oteen in miles?
Commentary
The purpose of this task is for students to translate between information provided on a map that is drawn to scale and the distance between two cities represented on the map. This task is a very straightforward application of the mathematics described in 7.G.A.1. This task would be appropriate for assessment.
Solutions
Solution: 1
A distance of nine miles means 9 quarter inches on the map. This is
9×14=94
or 214 inches between Candler and Canton on the map.
Map_problem_a_425ac563f0de413ec7618e8fe79c1b90
How many 14 inches are in 312 inches? To find this, we divide:
312÷14=72×41=14
So it is 14 miles between Chandler and Oteen.

The price of gas at Bob's Gas Station is $0.25 less per gallon than Phil's Gas Station. Which equation shows the price of gas at Bob's Gas Station?
A p = 2.59
OB. p = 2.79
oc. p= 2.759
OD p = 39
Answer: A
Step-by-step explanation:
The equation p = 2.5g shows the price of gas at Bob's Gas Station.
What is equation?The definition of an equation in algebra is a mathematical statement that proves two mathematical expressions are equal.
Types of Equations:
Linear Equation: More than one variable may be present in a linear equation. An equation is said to be linear if the maximum power of the variable is consistently 1.
Quadratic Equation:This equation is of second order. At least one of the variables in a quadratic equation needs to be raised to exponent 2.
Cubic Equation: A third-order equation is this one. At least one of the variables in cubic equations needs to be raised to exponent 3.
Rational Equation: A fractional equation having a variable in the numerator, denominator, or both is referred to as a rational equation.
the equation of price of gas at Phil's station is:
for p = 2.7g +0.25g
p(5) = 2.7*5+0.25*5
= 14.75 (which is not true)
hence,
p = 2.5g + 0.25*g
p(5) = 2.5*5 + 0.25*5
p(5) = 13.75
hence equation of price of gas at Bob's station is:
p = 2.5g

If the Volume of a box is 250 feet3 and the height is 5 feet and the length is 5
feet, what is the measurement of the width?
Answer:
10 feet
Step-by-step explanation:
Use the volume formula, V = lwh, to solve for w
Plug in the values we know:
V = lwh
250 = (5)(w)(5)
250 = 25w
10 = w
So, the width is 10 feet

If the distance from the center of a Ferris wheel to one of the seats is approximately 90 feet what is the distance traveled by a seated person, to the nearest foot, in four revolutions r=90 feet
Answer: 2261.9 ft
Step-by-step explanation: One trip around is one circumference of a circle. The circumference is 2πr. That's 2(π)(90 ft) = 565.4867 ft. Multiply by 4 trips around for a total distance of 2261.9 ft If you care about significant figures, then you only have report sig fig, so that's 2000 ft.
The total distance traveled by the seated person is 2260.8 feet.
How do you calculate the distance?Given that the distance from the center of the wheel to the seat is 90 feet. The seated person travels for 4 revolutions.
The distance traveled by the seated person in one revolution will be equal to the circumference of the wheel has a radius of r. Hence the circumference of the wheel is given below.
One revolution = [tex]2\pi r[/tex]
One revolution = [tex]2 \times 3.14\times 90[/tex]
One revolution = 565.2 feet
Hence the distance covered in four revolutions can be calculated as below.
Total Distance = [tex]4 \times 565.2[/tex]
Total Distance = 2260.8 feet
Hence we can conclude that the total distance traveled by the seated person is 2260.8 feet.

A museum curator needs to frame a rectangular painting. The painting is 30 inches by 17 inches. If the frame has a width of x on all sides, what is the quadratic function that models the area of the painting and frame?
Answer:
(30 + 2x) * (17 + 2x)
Step-by-step explanation:
Dimension of painting = 30 by 17 inches
Width of frame on all sides = x
Painting and frame takes the shape of a rectangle :
Area of rectangle = Length * Width
Area of painting = (30 * 17)
Area of frame ;
Length = (x + x) = 2x ;
Width = (x + x) = 2x
Area of frame = 2x * 2x
Equation for the Area of painting and frame :
(30 + 2x) * (17 + 2x)
