With speed=10 m/s, the rope will hit ground after 3.36 seconds.

Speed is a measure of how fast an object is moving, usually measured in units of distance per unit time, such as meters per second (m/s) or kilometers per hour (km/h). It is a scalar quantity, meaning it only has magnitude and no direction.

Mathematically, speed is defined as the distance an object travels per unit time. The formula for calculating speed is:

Speed = Distance / Time

where Distance is the distance traveled by the object, and Time is the time taken to cover that distance.

here, we have,

Now,

To find when the rope will hit the ground, we can use the kinematic equation:

y = vi * t + (1/2) * a * t²

where:

y = 50 m (the height of the cliff)

vi = 10 m/s (the initial velocity of the rope)

a = 9.8 m/s² (the acceleration due to gravity, acting downward)

t = time it takes for the rope to hit the ground

We can solve for t by setting y=50 and solving for t:

50 = 10t + (1/2) * 9.8 * t²

50 = t(10 + 4.9t)

t = 50/14.9=3.36 s

Therefore, the rope will hit the ground after 3.36 seconds.

The oven will heat up by 18 degrees in 1 minute at this rate.

What is expressions ?

Expressions can be simplified, evaluated, or manipulated using mathematical rules and operations. They are used in a variety of mathematical contexts, such as algebra, geometry, calculus, and more.

We can start by finding the rate of temperature increase per minute. Since the temperature rose 3 degrees in 1/6 of a minute, we can multiply both sides by 6 to find the rate per minute:

3 degrees ÷ (1/6 minute) = 18 degrees per minute

So the oven heats up at a rate of 18 degrees per minute. To find how much the oven will heat up in 1 minute, we simply multiply the rate by the time:

18 degrees per minute × 1 minute = 18 degrees

Therefore, the oven will heat up by 18 degrees in 1 minute at this rate.

Answer:

the answer is multiply (200.96)(22)

Step-by-step explanation:

you have to multiply.

The value of m if the ratio of their heights is equal to 1:m is 4/3.

Ratio is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.

We are given that;

Area of A=144cm²

Area of B=256cm²

Ratio of heights= 1:m

Now,

The ratio of the areas of two similar solids is equal to the square of the ratio of their corresponding heights. So, we have:

(area of A) / (area of B) = (height of A)^2 / (height of B)^2

Substituting the given values, we get:

144 / 256 = 1^2 / m^2

9 / 16 = 1 / m^2

Multiplying both sides by m^2, we get:

9m^2 / 16 = 1

Multiplying both sides by 16/9, we get:

m^2 = 16/9

Taking the square root of both sides (and noting that m must be positive since it is a length), we get:

m = 4/3

Therefore, by the given ratio answer will be 4/3.

Answer: 15 3/4 cups

In order to figure out how much peanut butter they have used we must multiply our amount by the number used.

4 1/2 times 3 1/2 can also be written as 4.5 and 3.5, respectively.

So our equation would be 4.5 x 3.5

4.5 x 3.5 is 15.75  

The number .75 can be written as the fraction 3/4, since 75 is 3/4th of 100.

This means the cafeteria used 15 3/4 cups of peanut butter.

I hope this helped & Good Luck <3 !!!

To calculate the amount of peanut butter used, multiply the number of jars (3 1/2) by the quantity in each jar (4 1/2 cups). This equals 15 3/4 cups of peanut butter.

To find out how many cups of peanut butter the cafeteria has used, we need to multiply the number of jars used by the number of cups in each jar. We know that there are 4 1/2 cups in one jar of peanut butter and the cafeteria has used 3 1/2 jars. So, we multiply 4 1/2 by 3 1/2 to get the total number of cups used.

This can be done by converting the mixed fractions to improper fractions: 4 1/2 becomes 9/2 and 3 1/2 becomes 7/2. Multiplying these gives 63/4, which converts back to the mixed number 15 3/4.

So, the cafeteria has used 15 3/4 cups of peanut butter.

What is Algebraic expression ?

Algebraic expression can be defined as combination of variables and constants.

The problem asks us to construct a boxplot and identify the 5-number summary of a set of data. The data represents the amounts of strontium-90 (in millibecquerels, or mBq) in a sample of baby teeth from residents born after 1979. The data is as follows:

124, 127, 131, 135, 138, 142, 142, 143, 147, 150, 154, 156, 157, 160, 163, 168, 170, 171, 174, 181

To construct the boxplot, we need to first find the 5-number summary, which consists of the minimum value, the first quartile (Q1), the median (Q2), the third quartile (Q3), and the maximum value. We can find these values by putting the data in ascending order and then using the following formulas:

Q1 = median of the lower half of the data

Q2 = median of the entire data set

Q3 = median of the upper half of the data

Using these formulas, we find the 5-number summary to be:

Minimum value: 124 mBq

Q1: 138 mBq

Median: 150 mBq

Q3: 168 mBq

Maximum value: 181 mBq

We can now use this information to construct the boxplot. The horizontal axis represents the values in the data set, and the vertical axis represents the frequency or density of those values. The boxplot consists of a box that extends from Q1 to Q3, with a line segment drawn through the box at the median (Q2). Whiskers extend from the top and bottom of the box to the minimum and maximum values, respectively, unless there are outliers. Outliers are plotted as individual points beyond the whiskers.

Therefore, In this case, the boxplot is option A, which shows the box extending from 130 to 165.5 mBq, with a line segment drawn through the box at 160.75 mBq. The whiskers extend from 114 to 201 mBq, with no outliers.

If to display charts and other educational material, your teacher has requested that two rows of strips be placed around the entire room. the total length of strips is: 4L + 4W.

To find the total length of strips required, we need to know the dimensions of the room. Let's assume that the room has a length of L and a width of W.

If we place two rows of strips around the entire room, one at the top and one at the bottom, the length of each strip will be equal to the perimeter of the room.

The perimeter of the room can be calculated as:

P = 2L + 2W

So, the length of strips required for one row around the room will be:

L1 = P = 2L + 2W

Since we need two rows of strips, the total length of strips required will be:

L2 = 2L1 = 2(2L + 2W) = 4L + 4W

Therefore, the total length is 4 times the length of the room plus 4 times the width of the room.
