Answer:

<u>6.89 cm</u>

Step-by-step explanation:

Here, the equation is :

  • V = 1/3Bh

Substituting the known values :

  • 34 = 1/3 x 14.8 x h
  • 102 = 14.8h
  • h = 102/14.8
  • h = <u>6.89 cm</u> (approximately)

<h3>Answer:</h3>

height: 6.9 cm

<h3>Explanation:</h3>

\sf Volume \ of \ Pyramid = \dfrac{1}{3} \ x \ Base \ Area \ x \ Height

<h3>Here provided Information:</h3>

<u>Volume</u>: 34 cm³

<u>base area</u>: 14.8 cm²

<h3 /><h3>Solve for Height:</h3>

\sf \rightarrow  \dfrac{1}{3} \ x \ 14.8 \ x \ Height = 34

<u>change side</u>

\sf \rightarrow  Height = \dfrac{34(3)}{14.8}

<u>simplify following</u>

\sf \rightarrow  Height = 6.891892

<u>rounded to nearest tenth</u>

\sf \rightarrow  Height = 6.9

A jar contains a combination of 60 nickels and dimes worth a total of $4.30. suppose that is deemed desirable to determine how m
Taya2010 [7]
We will represent everything in cents
nickles are worth 5 cents and dimes are 10 cents
n=number of nickles
d=number of dimes



60 total coins
n+d=60


total is 430 cents

5n+10d=430
divide both sides by 5
n+2d=86

we gots

n+d=60 and
n+2d=86
eliminate

multiply first equation by -1 and add to 2nd equation

-n-d=-60
<u>n+2d=86 +</u>
0n+1d=26

d=26

so

n+d=60
n+26=60
n=34


34 nickles and 26 dimes

You have a bag with 100 pennies. One of the 100 pennies is weighted so that it lands on heads 90% of the time. The rest of them
masha68 [24]

Answer:

0.160275

Step-by-step explanation:

P(5 time heads) =P(fair penny and 5 time heads + weighted penny and  5 time heads)

probability of fair penny = 99/100 (as one is removed)

probability of heads = 50% = 0.5 flipped 5 times

probability of weighted penny = 1/100

probability of heads for this penny = 90% = 0.9

substituting, we have

=(99/100) * (1/2)*5  +  (1/100) * (0.9)5  = 0.036842

hence from Bayes theorem

P(weighted penny | 5 time heads) =P(weighted penny and 5 time heads) / P(5 time heads)

=(1/100)*(0.9)5 /0.036842 =0.160275

  • sinB = 12/13
  • cosB = 5/13
  • tanB = 12/5

Here as by the given information ,

♦ sinA = Opposite/Hypotenuse

♦ cosA = Adjacent/Hypotenuse

♦ TanA = Opposite/adjacent

So here we need to find the same for angle B so we need to use the same formulas for angle B also .

→ sinB = Opposite/Hypotenuse = 12/13

→ cosB = Adjacent/Hypotenuse = 5/13

→ tanB = Opposite/Adjacent = 12/5
