HELP ! In right triangle RST, measure of angle S = 90° and measure of angle R ≠ measure of angle T. If cos(R) = a and sin(R) = b, which is equal to cos(T)/sin(T)?

The choices are

a+b
a-b
b-a
ab
a/b
b/a

Answer:

200 miles

Step-by-step explanation:

Given data

Rapid Rental Car

charges a $55 rental fee

$20 for gas, and

$0.65 per mile driven

let the number of miles be x, the total charges y

y=55+20+0.65x

y= 75+0.65x----------1

Capital Cars

charges $55 for rental and gas and

$0.75 per mile.

let the number of miles be x, the total charges y

y=55+0.75x

y= 55+0.75x----------2

Required

The number of miles driven before the two Rental companies charge the same amount

equate 1 and 2

75+0.65x= 55+0.75x

collect like terms

75-55= 0.75x-0.65x

20= 0.1x

x= 20/0.1

x= 200miles

Hence the distance will be 200 miles for the charges to be the same

Answer:

x = 60

Step-by-step explanation:

So, ever triangle, no matter what shape or size, is always going to equal 180 degrees. You start off by trying to find angle L which is 71. The way you find this is you subratch 109 from 180 which ultimately gives you 71.

180 - 109 = 71

After that you have to add what you already have (49 degrees) with what you just found (71 degrees)

49 + 71 = 120

Now that you have 120, you have to again subtract 180 by 120 to get your answer, 60 degrees. And that's it.

180 - 120 = 60

Step-by-step explanation:

Answer:

An Enlargement is the only transformation that changes the size of a shape. Two items of information are required to enlarge a shape: the Centre of Enlargement and the Scale Factor. ... If a shape is being enlarged by a scale factor of 2, the distance from the centre of enlargement to each vertex will be twice the size.

Answer: 130 ft

Step-by-step explanation:

a^2 + b^2 = c^2

Where a and b are the legs that form the right angle and c is the hypotenuse (the side directly opposite of the right angle)

50^2 + 120^2 = c ^2

2,500 + 14,400 = c^2

16,900 = c^2

Take the square root of 16,900 to get c.

C = 130

Hypotenuse length is 130

Answer:

B

Step-by-step explanation:

Since UV is a tangent then ∠ WUV = 90°

WZ = WU = x - 1 ( both radii of the circle ) , then

WV = x - 1 + 2 = x + 1

Using Pythagoras' identity in the right triangle

WU² + UV² = WV² , that is

(x - 1)² + (2x - 4)² = (x + 1)² ← expand factors using FOIL

x² - 2x + 1 + 4x² - 16x + 16 = x² + 2x + 1

5x² - 18x + 17 = x² + 2x + 1 ← subtract x² + 2x + 1 from both sides

4x² - 20x + 16 = 0 ← divide through by 4

x² - 5x + 4 = 0

(x - 1)(x - 4) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 1 = 0 ⇒ x = 1

x - 4 = 0 ⇒ x = 4

But x ≠ 1 as radius x - 1 = 0

Thus x = 4 → B

Step-by-step explanation:

3÷1/5=3×5=15

when you want to divide by a fraction (n/d), flip the numbers and make multiply sign, but make sure always flip the second number (the number after the divide sign) and not the first and change the divide to multiply

Answer:

The explicit formula for the geometric sequence is [tex]c(n) = -40\cdot \left(\frac{1}{2} \right)^{n-1}[/tex].

Step-by-step explanation:

By definition of geometric sequence, we should use the following expression:

[tex]c(n) = c_{1}\cdot r^{n-1}[/tex], [tex]n \ge 1[/tex] (1)

Where:

[tex]c_{1}[/tex] - First term.

[tex]r[/tex] - Geometric rate.

[tex]n[/tex] - Position of the element within the series.

If we know that [tex]c_{1} = -40[/tex] and [tex]r = \frac{1}{2}[/tex], then the explicit formula for the geometric sequence is:

[tex]c(n) = -40\cdot \left(\frac{1}{2} \right)^{n-1}[/tex]

The explicit formula for the geometric sequence is [tex]c(n) = -40\cdot \left(\frac{1}{2} \right)^{n-1}[/tex].

Answer:

Step-by-step explanation:

Technically we cannot solve this without knowing how many days a week that she works.

f=(16mi*d)(gal/19mi)

f=(16/19)d

We would have to assume that she works a certain amount of days. If we assume she works every day

f=7(16/19)=112/19, approximately 5.9 gal

Answer: The possible number of minutes is 5 minutes.

Step-by-step explanation: First, we should subtract: 46 - 16, since we already have 16 liters and need to get up to 46 liters. 46 - 16 gives us 30. 30 means that it is the liters needed to be filled.

Step-by-step explanation 2: Next, we know that 6 liters is filled every minute. So, basically just do 30 divided by 6, which gives us 5. 5 means the minutes.

Sooo, The possible number of minutes to fill the tank by 6 liters would be 5 minutes

I tried to explain it the best way I could. Hope it isn't confusing.

Answer:

∠6 = 125°

Step-by-step explanation:

__________________________________________________________

FACTS TO KNOW :-

When any 2 lines intersect each other at any point , the vertical angles are always equal to each other .

__________________________________________________________

According to the figure ,

∠6 is present vertically opposite to the angle whose measure is 125°.

∴ Hence ∠6 = 125°.

Answer:

38

Step-by-step explanation:

A triangle is 180 degrees.

You have to add 99 and 43 first.

99 + 43 = 142

You then subtract 142 from 180 to find the missing angle.

180 - 142 = 38
