Step-by-step explanation:
Three hundred sixty five ten thousands means 3 hundred and 65 thousands
The number will be written in figures as 365,000
The hundred defines the 300 and the sixty-five ten thousands define 65,000
ten thousands is added in the number to define the nature of sixty-five.
Round 757,960 to the nearest hundred thousand.

You want to rent a car for the day.Prestige car rentals charges $47 plus $0.07 per mile to rent a midsize vehicle . Gateway Auto changes a $35 fee plus $0.12 per mile for the same car. For what number of miles will both companies charge the same price?
Answer:
240 miles
Step-by-step explanation:
Given that:
Charges offered by Prestige car rentals for renting a midsize vehicle:
Fixed charges = $47
Per mile charges for renting a midsize vehicle = $0.07
Charges offered by Gateway Auto for renting a midsize vehicle:
Fixed charges = $35
Per mile charges for renting a midsize vehicle = $0.12
To find:
Number of miles for which both the companies charge the same price?
Solution:
Let the number of miles for which both the companies will charge the same price = [tex]x[/tex] miles
Charges for one mile by Prestige car rentals = $0.07
Charges for [tex]x[/tex] miles by Prestige car rentals = $0.07[tex]x[/tex]
Total charges by Prestige Car rentals = $47 + $0.07[tex]x[/tex]
Charges for one mile by Gateway Auto = $0.12
Charges for [tex]x[/tex] miles by Gateway Auto = $0.12[tex]x[/tex]
Total charges by Gateway Auto = $35 + $0.12[tex]x[/tex]
As per question statement, the charges are same:
[tex]\$47 + \$0.07x = \$35 + \$0.12x\\\Rightarrow 12=0.05x\\\Rightarrow x=\dfrac{1200}{5}\\\Rightarrow \bold{x=240\ miles}[/tex]
Find the length and width of the frame
Answer:
The width is - 4 the lengeth is - 7
Step-by-step explanation:
w*l = 28in²
w = ?
l = w+3
w=2
2+3 = 5
5*2 = 10
w = 3
3+3 = 6
6*3 = 18
w = 4
4+3 = 7
7*4 = 28
So,
W = 4 L = 7
Al llegar al hotel nos han dado un mapa con los lugares de interés de la ciudad, y nos han dicho que 5 centímetros del mapa representan 600 metros de la realidad. Hoy queremos ir a un parque que se encuentra a 8 centímetros del hotel en el mapa. ¿A qué distancia del hotel se encuentra este parque?
Answer:
La distancia real entre el hotel y el parque es 960 metros.
Step-by-step explanation:
Este es un caso de factor de escala, donde 5 centímetros en el mapa equivalen a 600 metros a escala real. Por tanto, la distancia entre el parque y el hotel en el mapa halla su equivalente mediante la siguiente regla de tres simple:
[tex]x = \frac{600\,m}{5\,cm}\times 8\,cm[/tex]
[tex]x = 960\,m[/tex]
La distancia real entre el hotel y el parque es 960 metros.

In this instance:
a = e
b = 3x
c = 7
Rewrite as the logarithmic equation:
[tex]log_{e}7 = 3x[/tex]
Solve. Evaluate [tex]log_{e}7[/tex] and use algebra to find x:

Answer:
XZ ≈ 14.4 cm
Step-by-step explanation:
Using the cosine ratio in the right triangle, that is
cos29° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{YZ}{XZ}[/tex] = [tex]\frac{12.6}{XZ}[/tex] ( multiply both sides by XZ )
XZ × cos29° = 12.6 ( divide both sides by cos29° )
XZ = [tex]\frac{12.6}{cos29}[/tex] ≈ 14.4 cm ( to 3 significant figures )

Answer:
AE = 30
GD = 5
GF = 10
Step-by-step explanation:
Centroid of medians divide median in the ratio 2 : 1
Therefore,
AG : GE : 2 : 1
Let AG = 2x & GE = x
Since, AG = 20....(given)
Therefore, 2x = 20
x = 20/2
x = 10
GE = x = 10
AE = AG + GE = 20 + 10 = 30
CG : GD : 2 : 1
Let CG = 2x & GD = x
Since, CG = 10....(given)
Therefore, 2x = 10
x = 10/2
x = 5
Since, GD = x
Therefore, GD = 5
BF = 30
2x + x = 30
3x = 30
x = 30/3
x = 10
GF = 10
Solve the system of equations - x - y = 6 and 5x -7y=66 by combining the equations
Answer: Let's solve for x.
−x−y=6
Step 1: Add y to both sides.
−x−y+y=6+y
−x=y+6
Step 2: Divide both sides by -1.
−x
−1
=
y+6
−1
x=−y−6
Answer:
x=−y−6
Let's solve for x.
5x−7y=66
Step 1: Add 7y to both sides.
5x−7y+7y=66+7y
5x=7y+66
Step 2: Divide both sides by 5.

So, 180 - 118 = 62
which linear function represent the table?
Answer:
Step-by-step explanation:So, if the graph is a straight line, it is the graph of a linear function. From a table, you can verify a linear function by examining the x and y values. The rate of change for y with respect to x remains constant for a linear function. This rate of change is called the slope.Mar 9, 2011

The equation y = 40x shows the number
of words Diego types in x minutes. What is
the constant of proportionality?
Answer:
40
Step-by-step explanation:
i would say 40? because it will be a constant for how many times you do X. for example if it's Y = 40 (2) it would equal 80 because no matter what number you put in X 40 will have to be multiplied
