Explain why all squares are similar????? and please help with question below!!!!!!!!!!!!!

Answers

Answer 1

Answer: that's not a squre
anyway, we use ratios
base:person to corner=28:8
height to height=x:5
so
28/8=x/5 becasue same ratio
28/8=14/4=7/2
7/2=x/5
multiply
35/10=2x/10
35=2x
divide 2
17.5=x

x=17.5 feet

Dean is running to raise awareness and money for cancer. He finds 2 people who have pledged to donate money based on the distance he runs. His neighbor says he will donate $0.25 for every 40 feet Dean runs. His aunt also says that she will donate $24 for every mile he runs. If Dean runs a total of 3 miles during the cancer awareness run, how much money will he have raised based on these two donations?

sally can paint a room in 7 hours while it taks steve 9hours to finsh the same room. how ling will it take them to paint if they worked together?

Answers

How much part can sally paint in an hour ?
a ÷ 7 = a/7

And what about Steve ?
a ÷ 9 = a/9

Where, a is the total area of the room.

So, let the time taken by both of them to paint the room together be 't'

So,
t(a/7 + a/9) = a
t(9a/63 + 7a/63) = a
t(16a/63) = a
t = 63/16 ≈ 4 hr

Sally alone can paint the room in 7 hours.

In 7 hours Sally alone does the job.

In 1 hour Sally would do (1/7) of the job.

Steve can paint it alone in 9 hours.

In 9 hours Steve alone does the job.

In 1 hour Steve would do (1/9) of the job.

Both working together in 1 hour would do: (1/7) + (1/9).

(1/7)*(9/9) + (1/9)*(7/7) = 9/63 + 7/63 = (9 + 7) / 63 = 16/63

In 1 hour both will have done (16/63) of the job.

16/63 of the job will be done in 1 hour by both.

Therefore a 1 whole fraction of the job will be done in: 1 hour ÷ 16/63

   = 1 hour × 63/16

   = 63/16 hours = 3.9375 hours

It would take both 63/16 hours or 3.9375 hours.

Let f(x)=√4x and g(x)=x+6, whats the smallest number that is the domain of f^o g?

Answers

f(x) = √(4x)
g(x) = x + 6

(f ο g)(x) = f(g(x))
(f ο g)(x) = √(4(x + 6))
(f ο g)(x) = 2√(x + 6)

The smallest number that is the domain of (f ο g)(x) is -6.

A newborn baby's weight is recorded each month, from the day of birth until 12 months. one baby's weights, in pounds, are recorded below: 7.20, 9.15, 11.01, 12.56, 14.04, 15.43, 16.52, 17.68, 18.77, 19.69, 20.22, 21.05, 21.90 what is the average amount of monthly weight gain, rounded to the nearest hundredth of a pound, each month? a. 1.13
b. 15.79
c. 1.23
d. 16.52

Answers

Answer:

15.79

Step-by-step explanation:

To find the average amount of monthly weight gain, we need to find the average first.

Average is defined as the sum of the values (in our case value of weight in each month) and that sum divided by the number of values (in our case it is the number of months).

Finding the average:

$A=(7.20+9.15+11.01+12.56+14.04+15.43+16.52+17.68+18.77+19.69+20.22+21.05+21.90)/(13)$

Since there are 13 values so we sum up all the values and divided by the number of values.

$A=(205.22)/(13)=15.786\approx15.79$

When rounded to the nearest hundredth of a pound we get 15.79 pounds.

27 is the relationship linear, exponential, or neither? Options: a. Linear b. Exponential c. Neither

Answers

Answer: Here's my answer

Step-by-step explanation:

The relationship given, 27, is neither linear nor exponential.

In a linear relationship, the dependent variable (y) changes at a constant rate for every unit increase in the independent variable (x). This results in a straight line when plotted on a graph. However, the given value, 27, does not provide any information about how the variable changes in relation to another variable. Without this information, we cannot determine if the relationship is linear.

In an exponential relationship, the dependent variable (y) changes at an increasing or decreasing rate based on a constant ratio for every unit increase in the independent variable (x). This results in a curved line when plotted on a graph. Since the given value, 27, does not provide any information about the rate of change or the constant ratio, we cannot determine if the relationship is exponential.

Therefore, based on the given information, the relationship 27 is neither linear nor exponential.
