Answer:

No one.

Step-by-step explanation:

$\frac{(7^0)^3}{[tex]\\\frac{\frac{(7*3*2)^2}{(7*5)(7^0)^3}}{5^{-3} *5^ {-9}} = \frac{\frac{7^2*3^2*2^2}{(7*5)(1)}}{5^{-12}} =\frac{\frac{7*3^2*2^2}{5}}{5^{-12}} =\frac{7*3^2*2^2}{5^{-11}}= 7*3^2*2^2*{5^{11}}=1.23* 10^{10}$ } = \frac{1}{5^ {-12}} = 5^ {12}[/tex]

11. One card is drawn from an ordinary deck of 52 cards. Find the probabilities of drawing the following.

Scilla [17]

Answer:

3/4
4/13
7/26
2/13
5.52

Step-by-step explanation:

<u>(a)</u>

Probability (A heart or a black card) = 13 + 26 / 52
Probability (A heart or a black card) = 39/52
Probability (A heart or a black card) = 3/4

<u>(b)</u>

Probability (A heart or a jack) = 13 + 3 / 52
Probability (A heart or a jack) = 16/52
Probability (A heart or a jack) = 4/13

<u>(c)</u>

Probability (A heart and the ace of clubs) = 13 + 1 / 52
Probability (A heart and the ace of clubs) = 14/52
Probability (A heart and the ace of clubs) = 7/26

<u>(d)</u>

Probability (A 9 or a jack) = 4 + 4 / 52
Probability (A 9 or a jack) = 8/52
Probability (A 9 or a jack) = 2/13

<u>(e)</u>

Probability (The 9 of hearts or a jack) = 1 + 4 / 52
Probability (The 9 of hearts or a jack) = 5/52

An 8-sided die is formed when two square pyramids are attached by their bases. The perimeter of the base shape is 6 centimeters.

lawyer [7]

Answer:

7.5cm²

Complete question:What is the surface area of the 8-sided figure?

Step-by-step explanation:

Consider the half of the 8-sided die i.e the pyramid ABCDE:

As the base is 6 of the perimeter, so each side of the base is 6/4=3/2

Now, the distance between the tallest points is 2 cm, so the height of Pyramid ABCDE is 1 cm.

Considering the right triangle EOM:

EO=1, OM= 3/4 (it is half of AB=3/2) and EM is the hypothenuse, so by the pythagorean theorem length of EM is

$\sqrt{1+ ( \frac{3}{4} )^{2} }= \sqrt{1+ \frac{9}{16} }= \sqrt{ \frac{25}{16} }= \frac{5}{4} (cm)$

5. So side EBC has area

$\frac{1}{2}BC*EM= \frac{1}{2}* \frac{3}{2}* \frac{5}{4}= \frac{15}{16}$

6. The total area is 8*Area(EBC)= $8* \frac{15}{16}= \frac{15}{2}=7.5 ( cm^{2} )$

Can someone please help

ASHA 777 [7]

Answer:

They cost 730 all together.

Step-by-step explanation:

One the surface area of the hall is 310m^2.

so, 310 divided by 25 is 12.4, which means they need 13 tin of paint.

The cost for it is 13*10 which is 130.

For the area of the floor, it is 40*15, which is 600m^2.

Which costs 600.

So, 600+130=730.
