A pedestrian sees a cat stuck in the tree that is 40.4 feet tall and calls 911. A fire truck
arrives and sends a fireman up in a rescue lift to save the cat. If the rescue lift is ascending at
a 45° angle of elevation, how far must the rescue bucket reach to save the cat?
Answer:
the cat should be about 6 or 7 inches away
Step-by-step explanation:
I'm sorry if I was wrong I hope I help
Answer:
57.3 feet
Step-by-step explanation:
Make a right angle triangle. Angle is 45 degrees
hight is 40.4 which is opposite to this angle, that means it's opposite side. And the distance of the bucket to rescue cat is hypotenuse, that's what we are looking for.
apply trig ratio
Sinθ = opposite leg/ hypotenuse
[tex] \sin( 45) = \frac{40.4}{x} \\ x = \ \frac{40.4}{ \sin(45) } \\ x = 57.275 \\ x = 57.3[/tex]

Answer:
x>10
Step-by-step explanation:
Think of the < and > signs as arrow marks
Whichever direction the arrows pointing, that's where you should plot.
The line graph shown goes rightwards, so use the sign that looks like it's pointing right. (>)
Finally, don't use the greater than or equal to sign because the circle isn't colored in. This means that it doesn't include 10, only numbers higher than 10.

Answer:
c. 12x > 24
Step-by-step explanation:
Only one choice has the "greater than" symbol. It is C.
A number is the variable x.
The product of 12 and a number is 12 × x which is written simply as 12x.
12x is greater than 24.
The symbol for "greater than" is >.
Answer: c. 12x > 24
what fraction of a dollar is 7 dimes and 8 pennies
Answer:
78/100 or if simplified 39/50
Step-by-step explanation:
Add together the 70 cents and 8 pennies to get 78 cents. One dollar is 100 cents so you automatically get the fraction 78/100 and you can simplify by dividing it by 2 in order to get 39/50.

Answer:1.4.
Step-by-step explanation:
Finding the surface area
Answer: so you do length times width times height and then you divide by two
Step-by-step explanation:
The shopkeeper agrees to give him a total discount of $70, but charges $9 for every pen. what is the maximum number of pens he can buy now?
To determine the maximum number of pens he can buy, we need to consider the total discount of $70 and the cost of each pen, which is $9.
Assume he buys an "x" number of pens.
The total discount he receives can be calculated by multiplying the number of pens by the cost of each pen:
$9x
Based on, the shopkeeper agrees to give him a total discount of $70, so we have the equation:
$9x = $70.
To determine the maximum number of pens he can buy, we need to solve for "x".
Dividing both sides of the equation by $9:
x = $70 / $9.
x= 7.77.
Therefore, the maximum number of pens he can buy is 7.

Using a system of equations, it is found that there are 10 baskets that hold 4 meals in the shop.
What is a system of equations?A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the variables are given by:
Variable x: Number of baskets that hold 2 meals.Variable y: Number of baskets that hold 4 meals.There are 25 baskets in the shop, hence:
x + y = 25 -> x = 25 - y
They can hold a total of 70 meals, hence:
2x + 4y = 70
2(25 - y) + 4y = 70
2y = 20
y = 10

Answer:
x = 2, y = 13, z = 1
Step-by-step explanation:
2 * 2 * 13 * 13 * 17 is equal to 2x * 13y * 17z.
knowing that 2x = 2 * x
therefore

Find the least number which must be subtracted from 1381 so as to get a perfect square number. Also find the square root of the square number so obtained.
Answer:
12.
Square root = 37,
Step-by-step explanation:
40^2 = 1600
35^2 = 30 * 40 + 25 = 1225
So the requred square is between 35 and 40
38^2 = 1444
37^2 = 1369 - so its this one.
Required difference = 1381 - 1369 = 12.
mean: _.5
Median: 5._
Answer: Mean=4.5
Median=5.5
Step-by-step explanation:
MEAN= Add all of the numbers together then divide by 18 to get 4.5
Median=To find the median, first order your data. Then calculate the middle position based on n, the number of values in your data set. If n is an odd number, the median lies at the position (n + 1) / 2. If n is an even number, the median is the mean of the values at positions n / 2 and (n / 2) + 1. This should get you 5.5
3 . Which graph represents a function?
Answer:
There is no graph....
Step-by-step explanation:
But I believe this is the graph you are talking about
Therefor Graph D represents a function.
Write the equation of the line that is perpendicular to the graph of y=1/2x +6, and whose y-intercept is (0,-2).
keeping in mind that perpendicular lines have negative reciprocal slopes, let's check for the slope of the equation above
[tex]y = \stackrel{\stackrel{m}{\downarrow }}{\cfrac{1}{2}}x+6\qquad \impliedby \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array}[/tex]
so then
[tex]\stackrel{~\hspace{5em}\textit{perpendicular lines have \underline{negative reciprocal} slopes}~\hspace{5em}} {\stackrel{slope}{\cfrac{1}{2}} ~\hfill \stackrel{reciprocal}{\cfrac{2}{1}} ~\hfill \stackrel{negative~reciprocal}{-\cfrac{2}{1}\implies -2}}[/tex]
so we're really looking for the equation of a line whose slope is -2 and passes through (0 , -2)
[tex](\stackrel{x_1}{0}~,~\stackrel{y_1}{-2})\qquad \qquad \stackrel{slope}{m}\implies -2 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{(-2)}=\stackrel{m}{-2}(x-\stackrel{x_1}{0}) \\\\\\ y+2=-2x\implies y=-2x-2[/tex]

simply because the right graph shows that the curve goes through
(4, 0) and (-4, 0)
and
(0, 3) and (0, -3)
but if I am mistaken about b showing that, please pick the graph that shows this.
the reason is to think when is the x term being 1, when y = 0, and when is the y term being 1, when x = 0.
these are some "cornerstones" for the graph based on the functional definition.

evaluate sin 315 without a calculator
Answer:
-0.7071.
Step-by-step explanation:
The value of function sin 315 is -1/2.
What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
Sin 315 degrees can be found by using the unit circle.
The unit circle is a circle with the radius of one centered at the origin of a coordinate plane.
Every point on the unit circle is a point that is one unit away from the origin.
The unit circle is used to help find the exact values of the trigonometric functions at specific angles.
The angle 315 degrees is in the fourth quadrant of the unit circle, so the x-coordinate is negative and the y-coordinate is negative.
Using the x-coordinate, we can calculate the sine to be -1/2.
Hence, the value of function sin 315 is -1/2.

deviation = ((absolute value of the difference between expected heads and observed heads) + (absolute value of the difference between expected tails and observed tails)) divided by total number of tosses. This value should always be positive.
1. In tossing one coin 10 times, what are your chances for tossing a head? a tail?: When I tossed one coin 10 times, I got heads 4 times and I got tails 6 times.
2. In tossing one coin 100 times, what are your chances for tossing a head? a tail?: I got heads 55 times and tails 45 times when I tossed one coin 100 times.
3. In tossing one coin 200 times, what are your chances for tossing a head? a tail?: When I flipped one 200 times, I got heads 92 times, and tails 108 times.
4. What is the deviation for 10 tosses?: 0.1
5. What is the deviation for the 100 tosses?
6. What is the deviation for 200 tosses?
7. How does increasing the total number of coin tosses from 10 to 100 affect the deviation?
8. How does increasing the total number of tosses from 100 to 200 affect the deviation?
When a coin is tossed ten times, the probability of getting a head will be 1/2.
How to solve the probability?In probability, one can either get a head or a tail. Therefore, when a coin is tossed ten times the probability of tossing a head will be:
= 5/10 = 1/2
In tossing one coin 100 times, the chances for tossing a head will be:
= 1/2 × 100 = 50
In tossing one coin 200 times, the chances for tossing a head will be:
= 1/2 × 200
= 100
In conclusion, the deviation for 10 tosses is 0.1
