Can someone please answer this for me

Mathematics
1 answer:
adoni [48]2 years ago

Answer:

x = -7, A = 65 degrees

Step-by-step explanation:

[It is important to know that in any triangle, the sum of all three angles is equal to 180 degrees]

Therefore,

x + 72 + x + 51 + 71 = 180

2x + 194 = 180 [collect like terms]

2x = -14 [subtract 194 from both sides]

x = -7 [divide both sides by 2]

To find A, we substitute the value of x into x + 72:

A = (-7) + 72

A = 65 degrees.

Hope this helps! :D

The probability that a 38-year-old white male will live another year is .99813. What premium would an insurance company charge t
alukav5142 [94]

Answer:

The insurance company should charge $1,873.5.

Step-by-step explanation:

Expected earnings:

1 - 0.99813 = 0.00187 probability of the company losing $1 million(if the client dies).

0.99813 probability of the company earning x(price of the insurance).

What premium would an insurance company charge to break even on a one-year $1 million term life insurance policy?

Break even means that the earnings are 0, so:

0.99813x - 0.00187(1000000) = 0

0.99813x = 0.00187(1000000)

x = \frac{0.00187(1000000)}{0.99813}

x = 1873.5

The insurance company should charge $1,873.5.

Last week 40 fifth graders went on a field trip to the science museum.
Artist 52 [7]
PART ONE:
To put this information into a fraction you write part over whole:
 8/40

To change this into a decimal you have to plug in 8÷40 into your calculator:
0.2

PART TWO:
After you subtract 8 from 40, there are 32 fifth graders left.
The fraction will look like this:
32/40

To change this into a decimal you have to plug in 32÷40 into your calculator:
0.8

I hope this was helpful!

Help me plz only 3 questions and answer all 3 of them
a_sh-v [17]
Ok so this is the first page
1.
78 pizzas. 20% of 65 is 13. Add that to 65 and you get 78 pizzas.
It is a 1.08% decrease. When you divide 65/60 you get 1.08. Im not 100% sure about this one

2.
Online store=$208 and the superstore=$224
The difference is $16 so it would be cheaper to get it at the online store

3.
It is $4000. For the first year you would multiply $20,000 by 5% which is 20000*.05=1000. Then multiply 1000 by 4 years to get $4,000
Instead of multiplying the 1000 by 4, multiply by 2 to get 2000. Subtract 4000-2000 to get 2000. You saved $2,000
