A cellular phone tower services a 20-mile radius. A rest stop on the highway is 5 miles east and 12 miles north of the tower. If you continue driving due east, for how many more miles will you be in range of the tower?
Answer: 11
I just need a explanation, thank you!
The tower will work within next 11 miles inasmuch the drives moves through the road.
How to determine a distance inside a cellular phone towerThe maximum distance corresponds to the radius of the tower ([tex]r[/tex]), in kilometers, the east direction corresponds to the +x semiaxis and the north direction corresponds to the +y semiaxis. The angle and magnitude of the rest stop are found below:
[tex]l = \sqrt{5^{2}+12^{2}}[/tex]
[tex]l = 13[/tex]
[tex]\theta = \tan^{-1}\left(\frac{12}{5} \right)[/tex]
[tex]\theta \approx 67.380^{\circ}[/tex]
To determine distance within the cellular phone tower works we need to solve the following system of linear equations representing vector components:
[tex]5 + x = 20\cdot \cos \theta[/tex] (1)
[tex]12 = 20\cdot \sin \theta[/tex] (2)
By (2):
[tex]\theta = 36.869^{\circ}[/tex]
By (1):
[tex]x = 11[/tex]
The tower will work within next 11 miles inasmuch the drives moves through the road. [tex]\blacksquare[/tex]

A room is 12 feet long, 14 feet wide, and 11 feet high. The walls, ceiling, and floor are all to be painted the same color. How many square feet must be covered with paint?
Answer:
908 feet²
Step-by-step explanation:
To paint walls, we will be looking for surface area.
Since this is a room and we have three measurements, we can assume there will be the floor, the ceiling, and four walls. This means we will be looking for 6 sides in total.
-> See attached for a diagram I made of the sides we need
-> Keep in mind opposite pairs of walls will be the same, and the floor and ceiling will be the same.
We end up with the following sides:
11 * 12
11 * 12
11 * 14
11 * 14
12 * 14
12 * 14
We can simplify this to the following:
(2(11 * 12)) + (2(11 * 14) + (2(12 * 14) = 908 feet²
908 feet² must be covered with paint.
A fundraiser is being held to raise money for a new school playground. Of every $20 raised, $16 will be spent on playground equipment. If the goal of the fundraiser is $320.00 for olayground eauipment, how much money will it need to raise?
To meet the goal of $320.00 for the playground, they need to raise a total of $400.00
How much they need to raise?
We know that for each $20 raised, they get $16 for the playground. They need to get $320.00 for the playground.
Taking the quotient:
N = $320.00/$16 = 20
This means that they need to raise $20 20 times, so they get $16 20 times which is equal to $320.
Then, we can conclude that they need to raise a total of:
$20*20 = $4,000

PLEASE HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!What is the solution to −3/4x+2≤−7 ?
x≥−12
x is greater than or equal to negative 12
x≥12
x is greater than or equal to 12
x≤12
x is less than or equal to 12
x≤−12
x is less than or equal to negative 12
Answer:
[tex]x\geq 12[/tex]
x is greater than or equal to 12
Step-by-step explanation:
We first start off with recognizing that this is an inequality, and that the answer choices involve solving for [tex]x[/tex].
I suggest that you write out the steps one-by-one and don't skip any so that making a mistake is less likely.
Rewrite the original equation:
[tex]-\frac{3}{4}x + 2 \leq -7[/tex]
Use reverse PEMDAS (Parentheses, Exponents, Multiplication/Division, Addition/Subtraction) order to isolate [tex]x[/tex]:
Subtract 2 from both sides: [tex]-\frac{3}{4} x \leq -9[/tex]
Divide both sides by [tex]-\frac{3}{4}[/tex] (this flips the inequality symbol since we're dividing by a negative number): [tex]x\geq 12[/tex]
Your final answer is:
[tex]x \geq 12[/tex]
x is greater than or equal to 12

The tree diagram represents an
experiment consisting of two trials.
The probability defined as P(A and C) is the probability of P(A) × P(B) = (0.6 × 0.3) = 0.18
The probability of A ; P(A) from the tree diagram is 0.6
The probability of B ; P(B) from the tree diagram is 0.3
The probability, P(A and B) equals ;
P(A) × P(B) = 0.6 × 0.3 = 0.18
Therefore, probability of A and B is 0.18

Given: m A = 60

Both angle D and angle C are 120
1. Find the x- and y-intercept of the line. (1 point)
x - y = 12
The x-intercept is when the value of the y-coordinate is 0.
[tex]x - 0 = 12\\ x = 12[/tex]
Thus the x-intercept is at (12,0).
The y-intercept is when the value of the x-coordinate is 0
[tex]0-y=12\\y = -12[/tex]
Thus the y-intercept is at (0,-12)
Find the y-intercept and the slope of the line.
y=2/3
Answer:
y-intercept = 2/3
Slope = 0
Step-by-step explanation:
Equation of Line is y=mx+c
where m is the Slope
and c is the y-intercept
so for our Problem
y=2/3
which can be rewritten as y=0x+2/3 (y=mx+c)
so Slope =m=0
and y-intercept = c = 2/3
solve for y in terms of x.

Which one is the smallest decimal .5 .53 .053 .503
Answer:
.053
Step-by-step explanation:
The decimal places go all the way out to the thousandths place. In order to properly compare all of the decimals, it's best to add zeroes in place of any empty decimal places in any of the numbers.
.5 would now be .500
.53 would now be .530
And the other two numbers are already in the thousandths place, so those don't need to be changed.
Now, we can put all the numbers next to each other and compare. You compare decimals the same way you compare normal numbers- just act as if the decimal points aren't there.
If the numbers were 500, 530, 053, and 503, we know that 053 would be the smallest number. Therefore, the decimal .053 is the smallest.

Answer:
2.2
Step-by-step explanation:
11÷5 because 20 goes into 100 5 tines hope this helps!:)
Answer:
a = 55
Step-by-step explanation:
1. Set up the equation: 0.2a = 11 (20% is equal to 0.2 because to convert a percentage to a decimal you divide it by 100. In math, "of" means "times" and "is" means "equals" so the equation is 0.2 x a = 11, which can be shortened to 0.2a = 11).
2. Divide both sides by 0.2. You will be left with a = 55.
