If the scale I make for the parking lot is 10 inches long, it should be 7.5 inches wide.
What is a scale?Scale is a term to refer to a drawing and design method in which an object or space and its actual measurements are taken as a reference and subsequently reduced or increased while maintaining the proportions between their measurements.
How to calculate the length of the width of the parking lot to scale?To calculate the width of the parking lot to scale, it is necessary to perform the following mathematical operation.
We need to figure out how much 100 yards is on the inch scale model. So if 400 yards is 10 inches we must divide this value by 4 as shown below:
10 ÷ 4 = 2.5Based on the above, 100 yards equals 2.5 inches on this model. So if your width is 300 yards, the length in inches would be 7.5 inches.

1. Which equation represents a line that has a slope of -3 and an x-intercept of 5?
Answer:
y=-5x+35
Step-by-step explanation:
Use the formula y = mx + b
m = slope, so plug in -5 as the slope
To find x-intercept we set y=0
We want the x-intercept to be 7 so we can plug that into the equation too
0=-5(7)+b
Lastly solve for b and you get your answer
Which is y=-5x-35 :) hope this helps

Step-by-step explanation:
find the value of mn if ab= 9cm, bc= 7.2cm, and LM= 12cm
Answer:
9.6 cm
Step-by-step explanation:
Since the shapes are similar, we can write a proportion. Let x be the length of MN.
9/12 = 7.2/x Write a proportion.
9x = 12(7.2) Use cross products.
9x = 86.4 Multiply.
x = 9.6 Divide both sides by 9.
Side MN is 9.6 cm.

A large western state consists of 3744 million acres of land. Approximately 89% of this land is federally owned. Find the number of acres that are not federally owned.
411.84 million acres
Step-by-step explanation:Hi there !
100% - 89% = 11% (not federally owned)
3744 m ............ 100%
x m........................11%
x = 11×3744/100
= 41184/100
= 411.84 million acres are not federally owned

Un establo con forma de triangulo rectangulo encierra 50 metros cuadrados. Si su lado menor mide cinco,el lado perpendicular a este, ¿Cuantos metros debe de medir?
Veremos que el otro lado del triangulo debe medir 20 metros.
¿Cuanto debe medir el otro lado?
Sabemos que para un triangulo rectangulo de catetos P y K, el area es:
A = P*K/2
En este caso, sabemos que el menor de los catetos mide 5 metros, entonces tenemos:
P = 5m
Y tambien sabemos que el area es de 50m^2, reemplazando eso en la ecuación de arriba obtenemos:
50m^2 = 5m*K/2
Ahora podemos resolver esto para K
(50m^2)/5m = K/2
10m = K/2
2*10m = K = 20m
El otro lado debe medir 20 metros.

Answer:
Step-by-step explanation:
Given the following 3 points:
x y
-56 66
-42 58
-28 50
Check the slope of two line segments between the three points:
(58 - 66)/(-42 - (-56))
= -8/14
= -4/7
(50 - 58)/(-28 -(-42))
= -8/14
= -4/7
As the slopes are the same, the 3 points are on a straight line with slope of - 4/7:
y = -4x/7 + C
Substitute x = -28 , y = 50 into the equation
50 = -4(-28)/7 + C
50 = 16 + C
C = 34
y = -4x/7 + 34
Y-intercept at x = 0:

Answer:
Second option from the top
Step-by-step explanation:
First, let us simplify x + 2 < -3
x + 2 < -3
x + 2 - 2 < -3 - 2
x < -5
Now we can more clearly see which graph is correct.
-> Since we are using < / > and not ≤ / ≥ the dot will be opened and not closed. This rules out the first and third options.
-> Next, we need the direction of the line. Since < is facing to the left, our line will also be going to the left.
-> To satisfy all requirements, since all graphs start at -5 already, the correct answer is the second option from the top.
Answer:
it's the second one
Step-by-step explanation:
it's all just common knowledge
the sign is a less than sign so the sign is an open dot. That eliminated two options. And whatever way the less than sign is pointing is the way the arrow goes
Dinner costs $34.00 You also leave a 20% tip. How much did you pay
in total?
PLEASE ANSWER QUICKLY
Answer:
$40.80
Step-by-step explanation:
First, convert the 20% to an actual number that can be used in a calculation. For percent, this is always done by simply dividing the percent, in this case, 20%, by 100%. So, the conversational term "20%" becomes 20% / 100% = 0.20 in terms of a real mathematical number.
Second, you need to find out what 20% of your $34.00 meal cost is. This is always done by multiplying 0.20 by $34.00, or 0.20 x $34.00=$6.80. So, the amount of tip you are going to leave is $6.80.
This makes the total cost of your meal (to write on your charge slip or other payment)
$34.00 + $6.80 = $40.80.
Answer:
$40.80
Step-by-step explanation:
If you pay for the original cost of the dinner AND leave a 20% tip then the total amount paid will be 120% of the original cost (100% + 20% = 120%).
Convert 120% into a decimal: 120% = 120/100 = 1.2
So 120% of $34.00 = 1.2 × 34 = $40.80
