Answer: L = 1.27 radians.

Step-by-step explanation:

Here we have a triangle rectangle, for the triangle rectangle and one given angle θ we have the relations:

cos(θ) = (adjacent cathetus)/hypotenuse

sin(θ) = (opposite cathetus)/hypotenuse

tan(θ) = (opposite cathetus)/(adjacent cathetus)

Here we have the adjacent cathetus = 18in, and the hypotenuse = 60in.

Sowe can use the cosine relation:

Cos(L) = 18in/60in = 0.3

Acos(cos(L)) = L = Acos(0.3) = 1.266

We want to round it to the nearest hundredth, so we would have:

L = 1.27 radians.

A bottle holds 5/12 gallon of water. How many bottles can be filled with 2 1/4<br> gallons of water?
tekilochka [14]

Answer: 0.185 gallons

Step-by-step explanation:

Divide 5/12 by 2 1/4

First convert the improper fraction to a proper fraction, 2 1/4 = 9/4

5/12 ÷ 9/4

= 5/12 × 4/9

= 5/27 = 0.185

Which of the following is the equation of
Neporo4naja [7]

Answer:

a) Option A is correct.

b) Option C is correct.

Step-by-step explanation:

a) Which of the following is the equation of  the line passing through the points (1, 1)  and (-3,5)?

We will use the equation

(y-y₁)=m(x-x₁)

m= (y₂-y₁)/(x₂-x₁)

m= (5-1)/(-3-1)

m= 4/-4

m= -1

Consider point (1,1) and Putting value of m

(y-y₁)=m(x-x₁)

(y-1)=1(x-1)

y-1=x-1

y=x-1+1

y=x

So, Option A is correct.

b) Which of the following is the equation of a  line with a slope of 0 passing through (2,5)?

The formula used is:

y= mx+b

Finding b:

5=0(2)+b

=> b = 5

So, equation is:

y = mx+b

y=0x+5

y=5

So, Option C is correct.

A student must have an average​ (the mean) on five tests that is greater than or equal to​ 80% but less than​ 90% to receive a f
Greeley [361]
<span>46 <= grade < 96 First, let's write the equation for the lower limit that the student must get for a B. (x + 92 + 82 + 88 + 92)/5 = 80 Multiply both sides by 5 giving x + 92 + 82 + 88 + 92 = 400 Subtract 92, 82, 88, 92 from both sides x = 400 - 92 - 82 - 88 - 92 = 46 So the student has to get 46 or higher on the test to make a B. Now let's compute the upper limit (x + 92 + 82 + 88 + 92)/5 < 90 Multiply both sides by 5 (x + 92 + 82 + 88 + 92) < 450 Subtract 92, 82, 88, 92 from both sides x < 450 - 92 - 82 - 88 - 92 ) = 96 So the student has to get a grade of less than 96 to get a B.</span>
