Answer: 1 in = 3.6 ft
Step-by-step explanation:
The small car is a model of the large car. The small car is 5 inches long while the large car is 18 feet long.
We currently have a ratio of: [tex]\frac{18 ft}{5 in}[/tex]
We need to get either the 18 or the 5 to one single unit.
18 ft : 5 in
Divide both sides by 5 to isolate 1 inch.
[tex]\frac{18}{5}[/tex] ft : [tex]\frac{5}{5}[/tex] in
Simplify.
3.6 ft : 1 in
We found that the ratio of the scale model is 1 inch of the model is equal to 3.6 ft of the real car.
Therefore, 3.6 ft = 1 in, which is equivalent to 1 in = 3.6ft

For his phone service, Ryan pays a monthly fee of $10, and he pays an additional $0.06 per minute of use. The least he has been charged in a month is $92.74. What are the possible numbers of minutes he has used his phone in a month? Use m for the number of minutes, and solve your inequality for m.
Answers
Answer:
$92.74 = 0.06m + $10
m = 1545.67 (or 1546 if rounded to the nearest whole minute)
Step-by-step explanation:
m represents the number of minutes, which we have been told are charged at $0.06 per minute.
$10 is the constant because he is charged this every month.
Set up the equation with these numbers:
92.74 = 0.06m + 10
Now solve the equation
Subtract 10 from both sides to get m by itself:
92.74 - 10 = 0.06m + 10 - 10
82.74 = 0.06m
Divide each side by 0.06 to get m as a whole number
92.74/0.06 = 1545.67
0.06m/0.06 = m
Therefore
m = 1545.67 (or 1546 if rounded to the nearest whole minute)

Q.1. The potter at a pottery store makes two sizes of vases. The larger size takes six hours to make, and the smaller size takes 1.5 hours to make. The potter works 30 hours a week. She needs to make at least six total vases a week, including at least two of each size. Give one example of how many of each type of vase the potter can make.
Answers
Answer:
Step-by-step explanation:
Let x and y be the large (x) and small (y) vases the potter makes in one week.
We are told that the large and small vases require 6 hours for each large(x) and 1.5 hours for each small (y) vase. The combination of large and small vases made in one week thus requires a total time of:
6x + 1.5y = total hours/week
We are told that the potter works 30 hours per week, so:
6x + 1.5y = 30 hours
We also learn that she needs to make at least 6 vases in a week, so:
x + y => 6
Plot the two equations:
6x + 1.5y = 30, and
x + y => 6
This will produce the attached grap, Vases1. The inequality appears as the shaded area in the upper area. Any point in the shaded area satisfies the inequality of x + y => 6. The x and y intercepts are at (0,6) and (6,0), representing either all large (x) or small vases (y).
The lines intersect at (4.67,1.33). This represents a fictional combination of 4.67 large and 1.33 small vases. This results in 6 vases (4.67 + 1.33) that require a total of 30 hours to make (6*4.67 + 1.5*1.33) = 30 hours. If you want to select whole number answers, they appear at (0,6), (2,4), (4,2), and (6,0). (x,y or large,small). All combinations result in 6 vases, but eould require less than the 30 hours of time available. Any whole number combination in the area below the line 6x + 1.5y = 30, but above the line x+y =>6 are valid, such as (4,4). This area is shown in Vases2. The valid area for making choices has the darkest shade, where the two inequalities are both satisfied.

Answers
The expression a/b * c/d is an illustration of number types
The truth value of 8.96 is yesThe truth value of 5√6 is noThe truth value of 15 is yesThe truth value of π/4 is yesHow to determine the true values of the numbers?The expression is given as:
a/b * c/d
Next, we test the given numbers
(a) 8.96
Express 8.96 as a fraction
8.96 = 896/100
Express the numerator and the denominator as products
8.96 = (224 * 4)/(50* 2)
Split the fraction
8.96 = 224/50 * 4/2
The above equation shows that 8.96 can be written in the form a/b * c/d.
Hence, the truth value of 8.96 is yes
(b) 5√6
Express 5√6 as a product expression
5√6 = 5 * √6
Evaluate the product
5√6 = 12.2474.....
The result of 5√6 is a non-terminating decimal
Hence, the truth value of 5√6 is no
(c) 15
Express 15 as a fraction
15 = 90/6
Express the numerator and the denominator as products
15 = (9 * 10)/(3 * 2)
Split the fraction
15 = 9/3 * 10/2
The above equation shows that 15 can be written in the form a/b * c/d.
Hence, the truth value of 15 is yes
(d) π/4
Express π as 22/7
π/4 = 22/7/4
Rewrite the expression as products
π/4 = 22/7 * 1/4
The above equation shows that π/4 can be written in the form a/b * c/d.
Hence, the truth value of π/4 is yes

Indira drew 3 animals: an eagle, a snake, and a shark. She drew each animal twice, once with green eyes and once with red eyes. Ten students chose their favorite drawing. Three of them chose the shark with red eyes.
How many possible outcomes are there in the sample space of her experiment? Based on the results, what is the experimental probability that a shark with red eyes is not picked, written as a percent?
(PLEASE HELP!!)
Answers
Since each of the 10 students has 3 choices, there are [tex]3^{10}[/tex] possible outcomes in the sample space of her experiment.
Using the probability concept, it is found that there is a 70% experimental probability that a shark with red eyes is not picked.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
For an experimental probability, these numbers of outcomes are taken from previous trials.
In this problem, out of 10 students, 3 choose the shark with red eyes, hence 7 did not choose them, thus:
p = 7/10 = 0.7 = 70%.
Hence, there is a 70% experimental probability that a shark with red eyes is not picked.
For the total number of outcomes, there are 10 students, each with 3 choices, hence there are there are [tex]3 \times 3 \times 3 \cdots \times 3 = 3^{10}[/tex] possible outcomes in the sample space of her experiment.

which is an equation of the axis of symmetry of the graph of the equation y= x^2-6x+2?
1) x=-3
2) y=-3
3) x=3
4) y=3
Answers
Answer:
x=3
Step-by-step explanation:
The equation is written in the form ax2+bx+c. As you can see, a=1, b=-6 and c=2. The axis of symmetry is worked out by x=−b2a.
−(−6)2(1) = 62=3
Substituted this value of x back into the equation to find the y coordinate.
y=(3)2−6(3)+2
y=9−18+2
y=−7q

Find the missing side lengths. ( BC and DE)
Answers
Answer:
BC= 24, DE= 15
Step-by-step explanation:
You can use the Pythagroean theorem which is a^2+b^2=c^2.
So AC is the hypotenuse, so a^2+10^2=26^2=a^2+100=676. Subtract 100, a^2=576. Then take the square root of 576 which is 24.
EC is the hypothenuse for triangle EDC, so a^2+36^2=39^2, a^2+1296=1521. Then subtract to 1296 to get 225. Then take the square root which is 15.

Two numbers whose sum is 29 and their difference is 15
Answers
Answer:
22 and 7
Step-by-step explanation:
Let x and y be the two numbers we are looking for:
The statement “their sum is 29” means x + y = 29
The statement “their difference is 15” means x - y = 15
we get this system:
x + y = 29 (1)
x - y = 15 (2)
Let’s solve it :
(1) + (2) ⇒ x + y + x - y = 29 + 15 ⇒ 2x = 44 ⇒ x = 44/2 = 22
Now we replace x by 22 in equation (1) :
22 + y = 29 ⇒ y = 29 - 22 = 7
A group of climbers begin climbing at an elevation of 6500 feet and ascend at a steady rate of 600 vertical feet per hour. what is their elevation after 3.5 hours?
Answers
y = mx + b (m is the slope and b is the y intercept)
slope is rise/run - the climbers 600ft (rise) every 1 hour (run) … m = 600/1
on the graph the x axis would be time and the y axis would be the climbers elevation.
at time(t) = 0 which is the same as saying x = 0 the climbers are already 6500 up so that is your y-intercept.
thus the equation is:
y = 600/1 x + 6500 or y = 600x + 6500
when time(t) or x = 3.5
y = 600(3.5) + 6500
y = 2100 + 6500
y = 8600
The climbers elevation after 3.5 hrs is 8600ft.
