Answer:

2.35

Step-by-step explanation:

Based on the annual premium, the cash value of the policy, and the number of years, the traditional net cost of this policy over the first 10 years is 5.76.

First, find the net cost over 10 years:

= Total premium over 10 years - cash value

= (1,608 x 10) - 13,740

= $2,340

The net cost per year is:
= 2,340 / 10

= $234

The traditional net cost of this policy, per thousand per year for the first 10 years is:

= 234 / 50,000 x 1,000

= 4.68

Yup, u need answer choices

The percentage of the calls were greater than 30 minutes in duration is 69%.

Let N = 77 Total long-distance calls

X= 24 calls are less than or equal to 30 minutes duration

Y = N - X= 77 - 24= 53 calls are greater than 30 minutes duration

To find the percentage of calls greater than 30 minutes duration. This goes thus:

= Number of calls greater than 30 minutes / Total calls

= 53 / 77

= 0.69

Therefore, 69% of the call were greater than 30 minutes in duration.

If f(x) = x² ₋ 4x ₋ 6 then we get the following answers for f(0),f(3) and f(-2) respectively. And the expression f(1/2) = f(7/2) and f(2₋h) = f(2₊h) is therefore proved.

f(0) = -6

f(3) = -9

f(-2) = 6

Given the function is f(x) = x² ₋ 4x ₋ 6

we need to find for f(0):

f(0) = 0² ₋ 4(0) ₋ 6

f(0) = ₋6

f(3) = 3² ₋ 4(3) ₋ 6

f(3) = 9 ₋ 12 ₋ 6

f(3) = ₋9

f(₋2) = (₋2)² ₋ 4(₋2) ₋ 6

f(₋2) = 4 ₊ 8 ₋ 6

f(₋2) = 6

we need to prove f(1/2)f(7/2)

now, f(1/2) = (1/2)² ₋ 4(1/2) ₋ 6

f(1/2) = 1/4 ₋ 2 ₋ 6

f(1/2) = 1 ₋ 8 ₋ 24 / 4

f(1/2) = ₋31/4

f(7/2) = (7/2)² ₋ 4(7/2) ₋ 6

f(7/2) = 49/4 ₋ 14 ₋ 6

f(7/2) = 49 ₋ 56 ₋ 24 / 4

f(7/2) = ₋31/4

therefore, f(1/2) = f(7/2)

f(2₋h) = (2₋h)² ₋ 4(2₋h) ₋ 6

f(2₋h) = (4 ₊ h² ₋ 4h) ₋ 8 ₊ 4h ₋ 6

f(2₋h) = h² ₊ 4 ₋ 4h ₋ 8 ₊ 4h ₋ 6

f(2₋h) = h² ₋ 10

f(2₊h) = (2₊h)² ₋ 4(2₊h) ₋ 6

f(2₊h) = 4 ₊ h² ₊ 4h ₋ 8 ₋ 4h ₋ 6

f(2₊h) = h² ₋ 10

therefore, f(2₋h) = f(2₊h)

Hence proved.

26% is equal to 26/100

you have to figure out a common denominator for all three numbers. the easiest for me was 600

to get from 1/6 to x/600 you multiply by 6 so you do the same to the top. equaling 100/600

for 26/100 you times top and bottom by 6 equaling 156/600

for 33/200 you multiply by 3 on both equaling 99/600

The partial products of 3706 × 4 is ( 3000 × 4 ) + ( 706 × 4 ).

Calculating the product of two or more numbers is the procedure known as multiplication in mathematics. When two integers are multiplied together in mathematics, the result is a product or an expression that describes the factors to be multiplied.

The decimal numeral system is widely used to express both integer and non-integer numbers. The way of representing numbers in the decimal system is known as decimal notation.

The given product is 3706 × 4 and can be written as:-

3706 × 4 = [ 3000 + 706 ] × 4

3706 × 4 = ( 3000 × 4 ) + ( 706 × 4 )

Step-by-step explanation:

The values of a and b are 8 and 54 respectively.

As WX and YZ are perpendicular to each other and they intersect at point V, so both ∠WVY and ∠XVY are 90°.

Given that,

∠WVY = (4a + 58)°

∠XVY = (2b - 18)°

Which means:

4a + 58 = 90

4a = 90-58

4a = 32

a = 32/4

a = 8

and 2b - 18 = 90

2b = 90+18

2b = 108

b = 108/2

b = 54°

hence we get the values of a and b as 8° and 54°

Let the cost of one tacos = t

Let the cost of one burritos = b

So, we have this system

                    t + b = 60      (eq-1)

2.50t + 4.00b = 175.50        (eq-2)

We take equation-1,

We can write,

              t + b = 60

              t= 60-b            (eq-3)

Substitute equation-3 into equation-2,

We can write,

          2.50t + 4.00b = 175.50

          2.50(60-b) + 4.00b = 175.50

 Multiply the values,

         2.5(60)-2.5b+4b = 175.5

         150-2.5b+4b = 175.50

Subtract the values,

           1.5b = 175.5-150

            1.5b = 25.5

             b = 25.5/1.5

Divide the values,

             b = 17

Replace the value 'b' in equation-3,
