Mathematics
1 answer:
STatiana [176]4 years ago

Answer:

B) 32.50

Step-by-step explanation:

First you need to figure out what information you need, as this is two parts

  • <em>31 year old</em>
  • <em>nonsmoker male</em>
  • <em>100,000</em>

     2.

  • <em>30 year old</em>
  • <em>nonsmoker female</em>
  • <em>75,000</em>

Using only the first two parts, we can figure out where their premium would be at 25,000

1 would be 25,000:5.50

2 would be 25,000:3.50

but you do not need what their premium would be at 25,000, so you need to multiply. to get 10,000 from 25,000, you need to multiply both sides by four. To get 75,000 from 25,000, you need to multiply both sides by 3.

  1. 25,000:5.50=100,000:22
  2. 25,000:3.50=75,000:10.50

so you get 22 and 10.50

add them and you get 32.50

I hope this helped.

If m∠SRQ = 6x + 2 and m∠QRP = 2x + 10, find the value of x . *
Neko [114]

Answer:

for m∠SRQ x =  3

for m∠QRP x = 5

Step-by-step explanation:

1. 6x +2. 6 is being multiplied by a number so to find that number we do teh opposite

6x/2 = 3

drop the x then u have x = 3

2. 2x+10. 2 is being muliplied by a number so to find that number we do teh opposite

10/2x = 5

drop the x then u have x = 5

Pls help :Find the missing side or angle.<br> Round to the nearest tenth.
Nitella [24]

Answer:

C° = 71.6056

Step-by-step explanation:

Law of Cosines: c² = a² + b² - 2abcosC°

Step 1: Plug in known variables

29² = 30² + 15² - 2(30)(15)cosC°

Step 2: Evaluate

841 = 900 + 225 - 900cosC°

-59 = 225 - 900cosC°

-284 = -900cosC°

71/225 = cosC°

cos⁻¹(71/225) = C°

C° = 71.6056

And we have our answer!

Someone help me with these questions pls-
Andrews [41]

When finding the reciprocal, it is basicaly flipping the numerator and denominator of the number. For instance, the reciporcal of 2 is 1/2, because the denominator of 2 would be 1. For an example more straight forward, the reciporacle of 3/5 is 5/3. This applied to the question goes as followed.

1. 3/5 is 5/3

2. 1/4 is 4

3. 1 is 1

Similarly when dividing fractions or an integer to a fraction, the fraction that is dividing the number turns into the reciprocal then you would multiply.

4.   3/(3/4) is 3*4/3= 4

5.   5/(3/4) is 5*(4/3)= 20/3

6.   8/(4/7) is 8*(7/3)= 56/3

7. 6/(3/5) is 6*(5/3)= 10

8. 2/(5/8) is 2*(8/5)= 16/5

9. 4/(8/9) is 4*(9/8)= 9/2

Mary purchases four book online. The book were the same price each, and the shipping fee was $7.25. If the total cost was $55.25
Sonja [21]

Answer:

The price per book that Mary purchased is $12

Step-by-step explanation:

Mary's total cost can be expressed as;

C=(p×n)+s

where;

C=total cost

p=price per unit of books

n=number of books purchased

s=shipping fee

In our case;

C=$55.25

p=unknown

n=4

s=$7.25

replacing;

55.25=(4×p)+7.25

4 p+7.25=55.25

4 p=55.25-7.25

4 p=48

p=48/4

p=12

The price per book that Mary purchased is $12
