Ramon places a mirror on the ground 45 ft from the base of a geyser. He walks backwards until he can see the top of the geyser in the middle of the mirror. at that point, Ramon eyes are 6 ft above the ground and he is 7.5 ft from the mirror. Use similar triangles to find the geyser

Answer:

16

Step-by-step explanation:

To find 80% of 20, multiply .80 x 20

.80×20 = 16

This is how you multiply percentages--put the decimal point 2 places to the left, then multiply.  In this case, you're looking at 80%, so move the decimal point two places to the left

80.0 becomes .80

Then multiply that by the number you're trying to find the percentage of

Please check the explanation.

Step-by-step explanation:

Given the expression

[tex]V=\sqrt[3]{x-1}+3[/tex]

Determining the domain:

We know that the domain of a function is the set of input values for which the function is defined.

From the given graph, it is clear that the function has no undefined points nor domain constraints.

Therefore, the domain is:

In other words:

[tex]\mathrm{Domain\:of\:}\:\sqrt[3]{x-1}+3\::\quad \begin{bmatrix}\mathrm{Solution:}\:&\:-\infty \:<x<\infty \\ \:\mathrm{Interval\:Notation:}&\:\left(-\infty \:,\:\infty \:\right)\end{bmatrix}[/tex]

Determining the range:

We know that the range of a function is the set of values of the dependent variable for which a function is defined.

It is clear from the graph that the range can be any real number.

i.e. the range is:

{y|y is a real number}

In other words,

[tex]\mathrm{Range\:of\:}\sqrt[3]{x-1}+3:\quad \begin{bmatrix}\mathrm{Solution:}\:&\:-\infty \:<f\left(x\right)<\infty \\ \:\mathrm{Interval\:Notation:}&\:\left(-\infty \:,\:\infty \:\right)\end{bmatrix}[/tex]

Tip: Try taking care of, that pet and make more money to buy eggs to trade or hatch and thats an easy way to get rich if you don't have robux

Step-by-step explanation:

No, sorry. But I have a tip/hack for everyone! (I don't know if it still works)! Get 3 cracked eggs, and 1 royal egg... take care of them all until their last need. Hatch your cracked eggs first, THEN the royal egg last ... there should be a legendary in the royale egg! I tried this two times and I got a legendary each time! <3

Answer:

2.5 hours

Step-by-step explanation:

Let t = time in hours for reach friend's house

(t-1.5) = time for friend to drive her home

:

Both trips are the same distance, Write a distance equation from this fact:

Distance = speed * time

Drive distance = Bike distance

Equation-

step1)   25 (t-1.5) = 10t          (here u multiply 25 by t and 25 by 1.5)

step2)  25t - 37.5 = 10t        (move 37.5)          

step3)  25t - 10t = +37.5      (subtract 25t from 10t)

step4)  15t = 37.5                 (divide 37.5 by 15)

step5)  t = 2.5                     (time it took Luke to reach his aunt's house)

Answer:

X=1/7

Step-by-step explanation:

In linear equation, 1.05 feet  the total distance traveled by the ball.

What are a definition and an example of a linear equation?

A linear equation with one variable is one that contains just one variable. It has the formula Ax + B = 0, with A and B being any two real numbers and x being an ambiguous variable with only one possible value. One such linear equation in one variable is 9x + 78 = 18.

dropped from 10 feet and caught at highest

So ,   10 / 9 = 1

 h = v² / 29  = 0.05 feet

  1 = 0.05 = 1.05 feet

Answer:

Frequency is 3

Step-by-step explanation:

A sine function repeats in periods and it's frequency can be gotten using:

y(x) = sin(2πfx) where f is the frequency

We are given x = 4sin(6πx) + 1

This can be rewritten as: x = 4sin(3*2πx) + 1

Therefore, our f = 3.

Hence frequency of the sine function is 3.

Answer:

Below in bold.

Step-by-step explanation:

26.

First convert each mixed number to an improper fraction:

-12 2/3 = -38/3

- 1 1/9 = -10/9

-38/3 = -10/9 * y

y = -38/3 / -10/9

y = -38/3 * -9/10

  = -38 * -3 / 10

  = 114/10

  = 57/5

  = 11 2/5.

27,

1 5/7 = 1 13/14 a

12/7 = 27/14 a

a = 12/7 / 27/14

  =  12/7 * 14/27

  = 24/27

  = 8/9.

Answer:

y=4x-9

Step-by-step explanation:

The equation of a line is typically written in slope-intercept form, which is y=mx+b. Here's what the variables mean:

y=the y-coordinate

m=the slope

x=the x-coordinate

b=the y-intercept (the point on the line that intercepts the y-axis)

The only values that we have to calculate to find the equation are the slope of the line and the y-intercept. Let's start off by finding the slope.

To find the slope of a line, we would need to find 2 points that fall on the line, [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] and plug them into the expression [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]. Let's use the points (1, -5) and (3, 3).

[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\frac{3-(-5)}{3-1}[/tex]

[tex]=\frac{3+5}{3-1}\\= \frac{8}{2}\\= 4[/tex]

Therefore, the slope of the line is 4.

To find the y-intercept, all we need to do is look at which point the line crosses the y-axis, and that point is -9.

Finally, we plug the slope and the y-axis into the equation y=mx+b as m and b.

y=mx+b

y=4x-9

I hope this helps!

Answer:

1. Answer is 160 m

2. Answer is 1500 m²

Step-by-step explanation:

perimeter = 2(l+b)

which implies 2( 28.3 + 53.7) m = 160 m

Area is length× breadth

which implies 28.3× 53.7 = 1500 m²
