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
Ella said that if she knows the lengths of just two sides of any triangle,
then she can find the length of the third side by using the Pythagorean
Theorem. Is Ella correct? Explain. Lesson 7-1
Answer:
Yes
Step-by-step explanation:
Pythagorean theorem is a^2+b^2 = c^2 where each letter is a side of a triangle. If you know 2 sides then there is only 1 unknown and 1 equation so you can easily find the third side by solving the equation.

Answer:
16, 104, 1000
Step-by-step explanation:
8*2
8*13
8*125
Answer:
1,120
Step-by-step explanation:
We start off the multiples of 8 with 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, 96, 104
The smallest positive 2 digit multiple is 16
The smallest 3 digit multiple is 104
We know 8 x 100 = 800, so we are still in 3 digits
Now we try 8 X 110 = 880
Now let's try 8 x 120 = 960
Now, 8 x 125 = 1,000 which is the smallest 4 digit number we can get
16 + 104 + 1000 = 1,120
Lynne is rolling a six-sided number cube repeatedly. Her goal is to roll an even number 23 times. How many times should Lynne expect to have to roll the number cube to result in an even number 23 times? Enter your answer in the box to correctly complete the statement
Using the binomial distribution, it is found that she should expect to roll the number cube 46 times.
What is the binomial probability distribution?It is the probability of exactly x successes on n repeated trials, with p probability of a success on each trial.
The expected number of trials until q successes is:
[tex]E_s(X) = \frac{q}{p}[/tex]
In this problem:
She wants 23 successes, hence q = 23.Of the six numbers on the cube, three are even, hence the probability of a success on a trial is of p = 3/6 = 0.5.Then:
[tex]E_s(X) = \frac{23}{0.5} = 46[/tex]
She should expect to roll the number cube 46 times.

If the condition f(-x) = -f(x) is satisfy then the function is an odd function. Then the odd function is f(x) = 6x³ + 2x.
What is an odd function?Odd Function - A true function f(x) is said to be an odd function if the output value of f(-x) is the same as the negative of f(x) for all values of x in the domain of f.
The equation should be stored in an odd function:
f(-x) = -f(x)
Then the functions are given below.
f(x) = 3x² + x
f(x) = 4x³ + 7
f(x) = 5x² + 9
f(x) = 6x³ + 2x
Then replace x with the negative x, then we have
f(x) = 3(-x)² + (-x) = 3x² - x =
f(x) = 4(-x)³ + 7 = -4x³ + 7
f(x) = 5(-x)² + 9 = 5x² + 9

Raylan opened a savings account with $100. After 5 years there is $122. 50 in the account. What is his simple interest rate?
4.5% annually
Step-by-step explanation:Simple interest is the amount of interest added to a singular sum of money at a fixed rate.
Formula
The formula for simple interest is A = P(1+rt). In this formula, A is the total amount of money in the account, P is the original amount deposited, r is the rate of interest as a decimal, and t is the time in years.
Calculations
To find the rate, plug the information we know into the formula above
122.50 = 100(1+r*5)Divide both sides by 100
1.225 = 1 + r*5Subtract 1 from both sides
0.225 = r*5Divide both sides by 5
0.045 = rThis gives us the rate as a decimal. So, to find the rate as a percent. Do this by moving the decimal 2 places to the right (or just multiply by 100, they do the same thing). This means that the rate of simple interest is 4.5%.

Suppose that r (cos(θ) + i sin(θ)) is a third root of 27 (cos(π/5) + i sin(π/5)), i.e.
[r (cos(θ) + i sin(θ))]³ = 27 (cos(π/5) + i sin(π/5))
Expand the left side using de Moivre's theorem:
r³ (cos(3θ) + i sin(3θ)) = 27 (cos(π/5) + i sin(π/5))
Matching up real and imaginary parts, we have
r³ cos(3θ) = 27 cos(π/5)
r³ sin(3θ) = 27 sin(π/5)
Right away we see that r³ = 27 ⇒ r = 3, which eliminates A.
We also have
(r³ sin(3θ)) / (r³ cos(3θ)) = (27 sin(π/5)) / (27 cos(π/5))
tan(3θ) = tan(π/5)
3θ = tan⁻¹(tan(π/5))
3θ = π/5 + nπ
(where n is an integer)
θ = π/15 + nπ/3
Now,
• n = 0 ⇒ θ = π/15 ⇒ D is a third root
• n = 1 ⇒ θ = π/15 + π/3 = 2π/5
• n = 2 ⇒ θ = π/15 + 2π/3 = 11π/15 ⇒ C is a third root

Step-by-step explanation:
You have:
[tex] \frac{16}{1} \frac{liters}{minute} [/tex]
You can use the conversion factors to convert liters to milliliters, and minutes to seconds:
1L = 1000mL
1 min = 60 sec
Therefore:
[tex] \frac{16}{1} \frac{liters}{minute} \times \frac{1000}{1} \frac{mililiters}{liter} \times \frac{1}{60} \frac{minute}{seconds} [/tex]
Liters cancel and minutes cancel. The units of mL per second is all that remains:

Lance, Rachael, and Jamie are playing catch. Lance throws the ball to Rachael, Rachael to Jamie, and Jamie back to Lance. The angle formed at Rachael's position measures 90°. The distance from Lance to Rachael is 45 feet, and the angle formed at Lance's position measures 55°. Lance is trying to determine the other measures created by their positions. Give each measurement rounded to the nearest thousandth of afoot. The angle formed at Jamie's position measures degrees.
Answer:
35°
64.267 ft
78.455 ft
Step-by-step explanation:
The given situation can be modeled as a right triangle (see attached).
The interior angles of a triangle sum to 180°
⇒ angle at Jamie's position = 180° - 90° - 55° = 35°
To find the other measures (distances), we can use trig ratios.
[tex]\sf \sin(\theta)=\dfrac{O}{H}\quad\cos(\theta)=\dfrac{A}{H}\quad\tan(\theta)=\dfrac{O}{A}[/tex]
where:
[tex]\theta[/tex] is the angleO is the side opposite the angleA is the side adjacent the angleH is the hypotenuseTo find the distance from Rachael to Jamie:
[tex]\implies \sf \tan(55^{\circ})=\dfrac{x}{45}[/tex]
[tex]\implies \sf x=45\tan(55^{\circ})[/tex]
[tex]\implies \sf x=64.267\:ft\:(nearest\:thousandth)[/tex]
To find the distance from Lance to Jamie:
[tex]\sf \implies \cos(55^{\circ})=\dfrac{45}{y}[/tex]
[tex]\sf \implies y=\dfrac{45}{\cos(55^{\circ})}[/tex]

4x + 5(3x - 10) = 74x + 15x - 50 = 719x = 57x = 3y = 3(3) - 10y = 9 - 10y = -1Solution is (3, -1)Answer:
x = 3y = -1Solution: (3, -1)
Step-by-step explanation:Given equations:
[tex]4x + 5y = 7[/tex][tex]y = 3x - 10[/tex]Step-1: Reorganize the equations with "y" on the L.H.S
[tex]\rightarrow \left \{ {{4x + 5y = 7} \atop {y = 3x - 10}} \right.[/tex]
[tex]\rightarrow \left \{ {{5y = 7 - 4x} \atop {y = 3x - 10}} \right.[/tex]
[tex]\rightarrow \left \{ {{5y = 7 - 4x} \atop y =-10 + 3x}} \right.[/tex]
Step-2: Make the x-variables the same on both equations
[tex]\rightarrow \left \{ {{3(5y = 7 - 4x)} \atop 4(y =-10 + 3x)}} \right.[/tex]
[tex]\rightarrow \left \{ {{15y = 21 - 12x} \atop 4y =-40 + 12x}} \right.[/tex]
Step-3: Add the equations
[tex]\rightarrow (15y + 4y) = (21 - 40) + (-12x + 12x)[/tex]
[tex]\rightarrow 19y = -19[/tex]
Step-4: Divide both sides by 19
[tex]\rightarrow \dfrac{19y}{19} = \dfrac{-19}{19}[/tex]
[tex]\rightarrow y = -1[/tex]
Step-5: Substitute the value of y into any equation
[tex]\rightarrow y = 3x - 10[/tex]
[tex]\rightarrow -1 = 3x - 10[/tex]
Step-6: Simplify the equation
[tex]\rightarrow -1 + 10 = 3x[/tex]
[tex]\rightarrow9= 3x[/tex]
Step-7: Divide 3 both sides
[tex]\rightarrow \dfrac{9}{3} = \dfrac{3x}{3}[/tex]
[tex]\rightarrow x = 3[/tex]
(Optional) Step-8: Convert the solution(s) into (x, y) form
[tex]\rightarrow (x, y) \rightarrow (x = 3; y=-1) \rightarrow (3,-1)[/tex]
Thus, the value of x and y is 3 and -1. The solution is (3, -1).

What number should be added to both sides of the equation to complete the square?
x2 - 6x = 5
Answer:
9
Step-by-step explanation:
The given equation is:
[tex]x^{2}[/tex] - 6[tex]x[/tex] = 5
To complete the square you have to add one number to both sides of the equation.
First, divide the coefficient of the term x by 2 and square the result. This number should then be added to both sides of the equation.
For the equation [tex]x^{2}[/tex] - 6[tex]x[/tex] = 5 the coefficient of the term x is -6.
(6 ÷ 2)² = 9
So you'll add 9 to both sides of the equation.
[tex]x^{2}[/tex] - 6[tex]x[/tex] (+ 9) = 5 (+ 9)
↓
[tex]x^{2}[/tex] - 6[tex]x[/tex] + 9 = 14
This can also be written as:
([tex]x[/tex] - 3)² = 14
