Find the value of x. 7/10=x/105

Mathematics
1 answer:
GalinKa [24]4 years ago
3 0

Answer:

The value of x is 73.5.

Step-by-step explanation:

Given:

7/10=x/105.

Now, to find the value of x.

\frac{7}{10} =\frac{x}{105}

So, to get the value of x we use cross multiplication:

\frac{7}{10} =\frac{x}{105}

By cross multiplying we get:

735=10x

By dividing both sides by 10 we get:

73.5=x

x=73.5

Therefore, the value of x is 73.5.

PLEASE HELP!!<br><br><br>Find the area of the following triangle enter the exact answer as a decimal
Marta_Voda [28]

Answer:

75.06239187

Step-by-step explanation:

1/2bh= Area of a Triangle

6^2+b^2=8.5^2 because we are missing a side we need to use the pythagorean theorem.

36+b^2=72.25

b^2=36.25

b=6.02

6.02+19= base

25.02

Now area

1/2bh

1/2 (25.02*6)

25.02*6= 150.1247

150.1247/2= 75.06239187 is Area

The above decimals before area are rounded.

Two different antibiotics can be used to treat an infection. Treatment with antibiotic 1 is known to be successful 80% of the ti
Deffense [45]

Answer: Option D

D. $108

Step-by-step explanation:

We must calculate the expected cost per patient to use treatment method B.

The expected cost for a discrete random variable x is:

C = \sum x_i * P (x_i)

Where x_i is the cost associated with the probability P(x_i)

In this case, the random variable x is represented by the cost of each treatment.

For treatment B there is a possibility that antibiotic 2 works, in that case the cost x would be $ 100 and P (x) = 0.9

There is also the possibility that it does not work, in this case the cost x would be $180 and the probability P (x) = 0.10

The expected cost  is:

C =\$100*0.9 + \$180*0.1\\\\C = \$108
