Answer:A

Step-by-step explanation:1 cup is equal to 8 fluid ounces so 48/8=6 and since he needs to drink 8 cups of water the answer is 2 more.

The number of cups of water Gethyn need to drink more is 2 cups. Therefore, option A is the correct answer.

Metric Conversion refers to the conversion of the given units to desired units for any quantity to be measured.

Given that, Gethyn drinks 48 fluid ounces of water in one day.

We know that, 1 ounce = 0.125 cups

Here, 48 fluid ounces = 48×0.125

= 6 cups

Number of cups of fluid = 8-6

= 2 cups

Therefore, option A is the correct answer.

Answer:

115

Step-by-step explanation:

Answer: x = 115 degrees

Step-by-step explanation:

a triangle we know all angles had up to 180 degrees

for the first triangle we have 65 + 90 = 155 then we do 180 - 155 = 25

so for the small triangle one angle is 25 degrees

now for the other triangle we have 80 + 60 = 140 then 180 - 140 = 40

so now we have all angles except x and to find that we do 25 + 40 = 65 then to find x do 180 - 65 = 115

Answer:

Assuming that a and b are not the hypotenuse then B would be equal to A, so B would equal 25m

The ladder is 5.09 m long

Step-by-step explanation:

Given that,

The height of the wall, P = 5 m

The base of the ladder is 1 m away from the wall.

We need to find the length of the ladder. Let it is H. We can solve it using the Pythagoras theorem. It can be given by :

[tex]H^2=P^2+B^2\\\\H^2=5^2+1^2\\\\H^2=25+1\\\\H=\sqrt{26} \\\\H=5.09\ m[/tex]

So, the ladder is 5.09 m long.

The exact value of the given trigonometric function sin(140°)cos(20°) – cos(140°)sin(20°) is -√3/2.

Trigonometric functions are defined as the functions which show the relationship between the angle and sides of a right-angled triangle.

To find the exact value of sin(140°)cos(20°) – cos(140°)sin(20°), we can use the angle addition formula for sine:

sin(A+B) = sin(A)cos(B) + cos(A)sin(B)

We can use this formula to rewrite the expression as:

sin(140°)cos(20°) – cos(140°)sin(20°) = sin(120°+20°) - sin(120°-20°)

Then, using the angle addition formula for sine, we get:

sin(120°+20°) - sin(120°-20°) = sin(120°)cos(20°) + cos(120°)sin(20°) - sin(120°)cos(20°) + cos(120°)sin(20°)

This simplifies to:

2sin(120°)cos(20°) = 2sin(120°)cos(20°)

The value of sin(120°) is -1/2, and the value of cos(20°) is √3/2, so the final value of the expression is:

2(-1/2)(√3/2) = -√3/2

Answer:

1. Not similar

2. Similar, ABC is similar to FED by SSS

Step-by-step explanation:

1. Not similar.

The interior angles of a triangle always have to add up to 180, and since the first triangle has angles 30 degrees and 90 degrees, you know the third angle will have to be 180 - 30 - 90 = 60 degrees.

The second triangle's third angle will have to be 50 degrees because 180 - 90 - 40 = 50 degrees.

Since the three angles of the triangle are not the same, they are not similar.

2. Similar, ABC is similar to FED by the SSS triangle similarity postulate.

First, AB is similar to FE because AB = 15 and FE = 5, so the scale factor is 3

Next, BC is similar to ED because BC = 9 and ED = 3, so the scale factor for these sides is also 3

Lastly, CA is similar to DF because CA = 12 and DF = 4, so the scal factor for this is also 3.

Since the scale factor for all of the sides is 3, these two triangles are similar.

Difference between 1/2 and 1/3 is 1/6 and 110 logs is 1/6 of the total logs

Answer:

C. 9.24

Step-by-step explanation:

x is the height here, looking at the triangle.

To find x, however, we first have to find the hypotenuse. To formula for that is b (side we know)/cos(α) (angle we know). Substitute b for 6, and α for 57.

6/cos(57) would equal about 11.0647.

Now back to x. To figure that out, subtract 6² from 11.01647². Then, find the square root of that.

x = √11.01647² - 6²

x = √121.3626112609 - 36

x = √85.3626112609

x = 9.23918888544335

x ≈ 9.24, so C is the answer.

The average rate of change of f(x) = 2x^2 - x - 4 over the interval -4 < x < 2 is -5.

To find the average rate of change of a function over an interval, we need to calculate the difference in the function values at the endpoints of the interval and divide it by the difference in the x-values.

The given function is f(x) = 2x^2 - x - 4.

Let's calculate the function values at the endpoints of the interval: -4 and 2.

For x = -4:

f(-4) = 2(-4)^2 - (-4) - 4 = 32 + 4 - 4 = 32.

For x = 2:

f(2) = 2(2)^2 - 2 - 4 = 8 - 2 - 4 = 2.

Now, we can calculate the difference in the function values: f(2) - f(-4) = 2 - 32 = -30.

Next, we calculate the difference in the x-values: 2 - (-4) = 6.

Finally, we can calculate the average rate of change by dividing the difference in the function values by the difference in the x-values:

Average Rate of Change = (f(2) - f(-4)) / (2 - (-4)) = -30 / 6 = -5.
