Hye Lim drank 4/3 gallons of water in 11/2 hours. At this rate, how long will it take her to drink 4 gallons of water?

Answers

Answer:

16.5 hours

Step-by-step explanation:

Here is the explanation. As Hye drinks 4/3 gallons of water in 11/2 hours, we have a constant rate. There are 12 thirds in 4, so we are trying to find how long it takes Hye to drink 12/3 gallon. In this case, 4/3x3=12/3, so we multiply 11/2 by 3 as well, which gives us 33/2 hours. 33/2 in decimal form is 16.5 hours. Hope it helps!

When a standard pair of six sided dice are rolled, what is the probability of getting a 6?
(Express your answer as a decimal rounded to the thousandsth place.)

Answers

Answer:

0.5 because it has a total of 6 sides

Probability of getting a 6 is equal to
1 - the probability of not getting a six.
The probability of not getting a six on a single roll is 5/6. The probability of not getting a 6 for 2 rolls is (5/6)^2.
The probability of getting a six is

1 - (5/6)^2 = 11/36.

D.pi/2, 3pi/4, 5pi/4, and 7pi/4

Answers

Answer:

Choice D:

π/2, 3π/4, 5π/4, and 7π/4

Step-by-step explanation:

correct on edg

The solution of the equation y = cos(2x) will be π/4, 3π/2, 5π/4, and 7π/4. Then the correct option is D.

What is the solution to the equation?

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

The equation is given below.

y = cos(2x)

The x-intercept of the equation in the interval 0 ≤ x < 2π will be given as,

y = 0

cos(2x) = 0

cos 2x = cos (n + 1) π/2

2x = (n + 1)π / 2

x = (n + 1)π / 4

x = π/4, 3π/2, 5π/4, 7π/4

The solution of the equation y = cos(2x) will be π/4, 3π/2, 5π/4, and 7π/4. Then the correct option is D.

A baby weighed 7.25 lb at birth. At the end of 8 months, the baby weighed 2.5 times its birth weight. How many pounds did the baby weigh at the end of 8 months?

Answers

Answer: 18.125 lbs

Explanation: The baby weighed 18.125 pounds at the end of eight months.

The baby weighed 7.25 lbs at birth. Eight months later, he weighed 2.5 or 2½ times its birth weight. Multiply 7.25 by 2.5  (which equals 18.125).

So now eight months later, he's 18.125 pounds.

7.25 x 2.5 = how much baby weighed= 18.125

8/12 the equibalent fraction

Answers

Answer:

An equivalent fraction for 8/12 could be 2/3

Step-by-step explanation:

It could be 2/3 because I divided 8 by 2 which is 4 and 12 by 2 which is 6 and the answer for that is 4/6 as a fraction, now notice how we could still divide the number by 2, so 4 divided by 2 is 2 and 6 divided by 2 is 3. So the answer as a fraction would be 2/3.

The purpose of this warm-up is to elicit the idea that tape diagrams can be used to think about fractions of a whole as percentages of the whole, which will be useful when students interpret and draw tape diagrams in a later activity. While students may notice and wonder many things about these images, the important discussion points are that there are two rectangles of the same length, one of the rectangles is divided into four pieces of equal length, and a percentage is indicated. 80 percent of what number is 100?
100 is 80% of 125

Steps to solve "100 is 80 percent of what number?"

We have, 80% × x = 100
or,
80
100
× x = 100
Multiplying both sides by 100 and dividing both sides by 80,
we have x = 100 ×

80
x = 125

The sequence of transformations R0,90 r x-axis is applied to XYZ to produce X’’ Y’’ Z’’. If the coordinates of Y’’ are (3,0),what are the coordinates of Y?

Answers

Answer:

Y = (0, 3)

Step-by-step explanation:

Notice that the first the transformation is a rotation of 90 degrees around the origin, and then a reflection around the x axis.

If a reflection around the x axis resulted in (3, 0)  that means the point was already on the x axis.

Then in order for a rotation in 90 degrees to take the point Y to (3, 0), Y must have been on the y-axis as (0, 3)

Answer:

Y = (0, 3)

To account for potential differences due to the type of ride and the possible interaction between the method of loading and unloading and the type of ride, a factorial experiment was designed. Use the following data to test for any significant effect due to the loading and unloading method, the type of ride, and interaction. Use α=α= .05.
