Factor : 49c^2 - 25d^6

Answers

Answer 1

Answer: 49c^2 - 25d^6
(7c)^2 - (5d^3)^2
(7c + 5d^3)(7c - 5d^3)

The answer is: (7c + 5d^3)(7c - 5d^3).

Answer 2

Answer: Hello,

$49c^(2)-25d^(6)=(7c)^2-(5d^3)²=[7c-5d^3][7c+5d^3]$

Henry is making a corn grits recipe that calls for 1/4 cup of corn grits for every 1/2 cup of water. How much water will he need if he uses 1 1/2 cups of corn grits? Enter the number in the box.

Answers

The quantity of water that would be needed if he uses $1(1)/(2)$ cup of corn grits is 3 cups of water.

Given the following data:

Quantity of corn A = $(1)/(4)$ cup of corn

Quantity of water A= $(1)/(2)$ cup of water

Quantity of corn B = $1(1)/(2)$ cup of corn

To determine the quantity of water that would be needed if he uses $1(1)/(2)$ cup of corn grits, we would apply direct proportion:

By direct proportion:

$(1)/(4)$ cup of corn = $(1)/(2)$ cup of water

$1(1)/(2)$ cup of corn = X cup of water

Note: $1(1)/(2)=(3)/(2)$

Cross-multiplying, we have:

$X * (1)/(4) = (1)/(2) * (3)/(2) \n\n(X)/(4) = (3)/(4) \n\n4X = 12\n\nX=(12)/(4)$

X = 3 cups of water

Answer: 3 cups of water will be needed .

Step-by-step explanation:

Since we have given that

$(1)/(4)\text{ cups of corn grits for every }(1)/(2)\text{ cups of water}$

so,

$\text{ For every }(1)/(4)\text{ cups of corn grits, cup of water is needed }=(1)/(2)$

$\text{ For every }1\text{ cup of corn grits, cup of water is needed }=((1)/(2))/((1)/(4))=2$

$\text{ For every }1(1)/(2)=(3)/(2)\text{ cups of corn grits, cup of water is needed }=(3)/(2)* 2=3$

Hence, 3 cups of water will be needed .

The shoe size for all the pairs of shoes in a person’s close are recorded. 7,7,7,7,7,7,7,7,7,7A. What is the mean?
B. What is the standard deviation?

Answers

Answer:

To find the mean (average) and standard deviation of the given shoe sizes, you can follow these steps:

A. Mean (Average):

The mean is calculated by adding up all the values and then dividing by the number of values.

Mean = (Sum of all values) / (Number of values)

In this case, the sum of all the shoe sizes is:

7 + 7 + 7 + 7 + 7 + 7 + 7 + 7 + 7 + 7 = 70

And there are 10 values.

Mean = 70 / 10 = 7

So, the mean (average) shoe size is 7.

B. Standard Deviation:

The formula for the standard deviation of a set of values can be quite complex, but for this small dataset with all values being the same, the standard deviation is essentially zero because there is no variability between the values.

In mathematical terms:

Standard Deviation = 0

So, the standard deviation for the given shoe sizes is 0.

Answer:

x=30

Step-by-step explanation:

2 times 1/2(x+6)=18 times 2

x+6=36

x+6-6=36-6

x=30

whomever is reporting me please stop(echo2155)

Answer:

Step-by-step explanation:

First you have to perform distributive property which is

2((x+6)=18) 2

Which will turn to

X+6=36

Then move the constant to the right so

X=36-6 then calculate

So the answer is 30

The value of x is 30

The schedule of a train that travels regularly between Pune and Delhi is given below. Station Arrive Depart Pune 5:30 a.m. 6:00 a.m. Mumbai 8:15 a.m. 8:30 a.m. Surat 4:30 p.m. 5:10 p.m. Mathura 12:40 a.m. 1:25 a.m. Delhi 4:40 a.m. −− How long will it take Sam to travel from Pune to Delhi on this train? hours minutes

Answers

To determine the travel time, we need to calculate the time difference between the departure from Pune and the arrival in Delhi. According to the schedule:

Pune departure: 6:00 a.m.
Delhi arrival: 4:40 a.m.

To calculate the travel time, we can subtract the departure time from the arrival time. However, since the arrival time is the next day, we need to consider that as well. Let's break it down:

From Pune to Mumbai: 8:30 a.m. - 6:00 a.m. = 2 hours and 30 minutes
From Mumbai to Surat: 5:10 p.m. - 8:30 a.m. = 8 hours and 40 minutes
From Surat to Mathura: 1:25 a.m. - 4:30 p.m. = 11 hours and 55 minutes
From Mathura to Delhi: 4:40 a.m. (next day) - 12:40 a.m. = 4 hours

Now, let's add up the individual travel times:

2 hours 30 minutes + 8 hours 40 minutes + 11 hours 55 minutes + 4 hours = 27 hours 5 minutes

Therefore, it will take Sam approximately 27 hours and 5 minutes to travel from Pune to Delhi on this train. ⏰
