Answer:

A) 7 is your answer.

Step-by-step explanation:

AD is congruent with AB, and because it is a kite, by definition, DC is congruent with BC. Set the two measurements equal to each other.

Set the two measurements equal to each other.

2x + 3 = 3x - 4

Isolate the variable x. Note the equal sign, what you do to one side, you do to the other.

First, subtract 3 and 3x from both sides.

2x (-3x) + 3 (-3) = 3x (-3x) - 4 (-3)

2x - 3x = -4 - 3

Simplify.

- x = -7

Isolate the variable. Divide -1 from both sides.

(-x)/-1 = (-7)/-1

x = 7

A) 7 is your answer.

a store sells a 3lb bag of oranges for $3.60 and a 5 pound bag of oranges for $5.25 what is the difference between the price per

Bumek [7]

The difference between the price per pound for the three pound bag of oranges and the price per pound for the 5 lb bag of oranges is $0.15

Step-by-step explanation:

Given

Price of 3lb bag = $3.60

Price of 5lb bag = $5.25

We have to calculate the per pound price for each bag to compare the per pound price for both

$Price\ of\ one\ pound\ in\ 3lb\ bag=\frac{3.60}{3}\\=\$1.20$

$Price\ of\ one\ pound\ in\ 5lb\ bag = \frac{5.25}{5}\\=\$1.05$

$Difference\ between\ two\ prices = 1.20-1.05\\=\$0.15$

The difference between the price per pound for the three pound bag of oranges and the price per pound for the 5 lb bag of oranges is $0.15

The formula for the area of a circle is A equals xr2 this formula allows you to find the area of a circle if you know the radius

iVinArrow [24]

Answer:

The relation for the area of circle with radius , Diameter , circumference is

A= $\pi$ × radius²

A = $\frac{\pi D^{2} }{4}$

A = $\frac{c^{2} }{4\pi }$

Step-by-step explanation:

Given as :

The formula for the area of circle = $\pi$ × radius²

I.e A = $\pi$ × radius²

Now If we know radius then

Area calculated as A= $\pi$ × radius²

If we know Diameter then

Area calculated as $\pi$ × ( $\dfrac{\textrm Diameter}{2}$ )²

Or, A = $\pi$ × ( $\dfrac{\textrm D}{2}$ )²

I,e A = $\frac{\pi D^{2} }{4}$

If we know the circumference then

∵ circumference = c = 2 × $\pi$ × radius

or, c = 2 × $\pi$ × r

from here we calculate radius

I.e r = $\frac{c}{2\pi }$

And So , Area ( A ) = $\pi$ × radius²

I.e A = $\pi$ × ( $\frac{c}{2\pi }$ )²

Or, A = $\frac{c^{2} }{4\pi }$

Hence The relation for the area of circle with radius , Diameter , circumference is

A= $\pi$ × radius²

A = $\frac{\pi D^{2} }{4}$

A = $\frac{c^{2} }{4\pi }$ Answer

Two cards are drawn from a standard 52-card deck, without replacement. Find the probability that they are both aces.

Delvig [45]

4 aces in a deck = 4/52 = 1/13
then without replacement, 3 aces in 51 cards
so
1/13 * 3/51
= 3/663
= 1/221

answer

for the area of the smaller semicircles

area = 1/2 x 3.142 x 5 x 5

area = 39.275cm²

for the larger circle

area = 1/2 x 3.142 x 10x 10

area= 157.1cm²

but since part of it is out and is replaced again

..total area of shaded part is 157.1cm² + 39.275cm² - 39.275cm²

area =157.1cm²
