Answer:

153.86 inches²

Step-by-step explanation:

How do we find the radius of a circle?

The radius of a circle is 1/2 of the diameter, so 14/2 = 7 inches

How do we find the area of a circle?

We can find the area of a circle by using πr², where r = radius. We're given the radius as 7 inches and pi as 3.14.

Solving

$3.14*7^2$
$3.14*49$
$153.86$

Therefore, the answer is 153.86 inches².

Have a lovely rest of your day/night, and good luck with your assignments! ♡

Answer:

the number of hamburgers sold on Thursday were 325.

Step-by-step explanation:

The total number of hamburger and cheese burger is missing

i will replace it with any figure, you can replace it wit your given data and you will get the solution.

A local hamburger shop sold a combined total of 593 hamburgers and cheeseburgers on Thursday

There were 57 fewer cheeseburgers sold than hamburgers

How many hamburgers were sold on thursday

Let h be the number of hamburgers and c be the number of cheeseburgers.

Using this information we can set up two equation as:

$h+c=593\\c=h-57$

Now we need to solve these two equations to get the value of number of hamburgers. For that we use substitution method as shown below:

$h+h-57=593\\2h-57=593\\2h=650\\h=325$

Therefore, the number of hamburgers sold on Thursday were 325.

4. The following intervals were plausible population proportions for a given sample. Find the margin of error in each case.

Vedmedyk [2.9K]

Answer: a. 0.15 b. 0.03 c. 0.055 d. 0.05

Step-by-step explanation:

For plausible intervals of population proportions , the margin of error is basically half of the difference between upper limit and lower limit.

a. Interval = From 0.35 to 0.65

Upper limit = 0.65

Lower limit = 0.35

Difference = Upper limit- Lower limit

= 0.65-0.35=0.30

Margin of error = (Difference)÷2 =(0.30)÷2=0.15

b. Interval = From 0.72 to 0.78

Upper limit = 0.78

Lower limit = 0.72

Difference = 0.78-0.72 = 0.06

Margin of error =(0.06)÷2=0.03

c. Interval = From 0.84 to 0.95

Upper limit = 0.95

Lower limit = 0.84

Difference =0.95-0.84= 0.11

Margin of error = (0.11)÷2 = 0.055

d.Interval = From 0.47 to 0.57

Upper limit = 0.57

Lower limit = 0.47

Difference = 0.57-0.47=0.10

Margin of error = (0.10)÷2=0.05

CAN SOMEONE HELP ME WITH THIS MATH ITS ABOUT FUNCTIONS HELPPPPPPPPPPPPPPPP

RSB [31]

Answer:

Step-by-step explanation:

The slope intercept form of a line is y=mx+b, where m is the slope of the line and b is the y intercept. Therefore, for A, the y intercept is 15, and for C it is -3. For B, the y intercept can be seen to be at -2, and for D it crosses the y axis at 2. Since -3 is the smallest of all of these, the correct answer is C. Hope this helps!

Savatey [412]

1 inch drop for every 25 inches length
40 feet= 12 x 40 = 480 inches
There are 19.2-25 inch lengths in 480 inches.
So there is a 19.2 inch drop in 40 feet.

Hope this helps :)
