Which number produces a rational number when added to 0.5?
A. –1.73205081…
B. 1/4
C. 0.54732871…
D. √3
Answer:
Option B is correct 1/4.
Step-by-step explanation:
To find : Which number produces a rational number when added to 0.5?
Solution :
A rational number is defined as number written in simple fraction or in p/q form.
An irrational number is defined as number which cannot be written in p/q form.
We know that,
A rational number adding a rational number gives you a rational number.
A rational number adding an irrational number gives you a irrational number.
Now we take each option and check.
Option A : -1.73205081…
Number has no end and have infinite number of digits so it is irrational number.
No, this number not produce a rational number.
Option B : 1/4=0.25
Number is in form p/q so it is rational number.
Yes, this number produce a rational number.
0.25+0.5=0.75 a rational number.
Option C : 0.54732871…
Number has no end and have infinite number of digits so it is irrational number.
No, this number not produce a rational number.
Option D : \sqrt{3}
\sqrt{3} cannot be written in ratio so it is irrational number.
No, this number not produce a rational number.

Answer:
1) 110*, 2) 84*, 3) 80*
Step-by-step explanation:
These are intersected parallel lines (with only 1 intersecting line), so having missing angles in the questions 1 and 2 opposite from the shown angle is giving the answer away. However, on answer 3, it is on the same side, so for that angle you will need to subtract the angle of the intersecting line by 100* to get 80*. Check by adding the two. 100* + 80* = 180*. Hope this helps.
p−1=5p+3p−8
Anyone help. Its due at 11:59 pm :( please help
Answer:
p = 1
Step-by-step explanation:
p - 1 = 5p + 3p - 8(collect like terms)
p - 1 = 8p - 8(add 1 on each side)
p = 8p - 7(subtract 8p on each side)
-7p = -7 (divide by -7)
p = 1

Step-by-step explanation:
A yellowfin tuna weighs about 380 pounds. A bluefin tuna weighs 620 about pounds. If one fish of each species were caught per day, about how many more pounds of bluefin tuna than yellowfin tuna would be caught in a week? Solve the problem two different ways.
Answer:
1680 pounds
Step-by-step explanation:
Given that :
Weight of yellow fin tuna = 380 pounds
Weight of bluefin tuna = 620 pounds
If one fish of each species were caught per day
about how many more pounds of bluefin tuna than yellowfin tuna would be caught in a week?
Total pound of bluefin tuna caught in a week:
7 * 620 = 4340
Total pound of yellow tuna caught in a week:
7 * 380 = 2660
(4340 - 2660) = 1680 pounds
The amount of money an employee earns is proportional to the number of hours worked. If the employee works 40 hours and earns $1,100, how much does the employee earn per hour?
Answer: $27.5
Step-by-step explanation:
From the question, we are informed that employee works 40 hours and earns $1,100, to calculate the amount that the employee earn per hour will be:
Amount earned = $1100
Number of hours worked = 40 hours
Amount earned per hour = $1100/40 = $27.5

If f(x) = 3x + 2, then find the value of x such that f(x) = -4.
Answer:
See Below
Step-by-step explanation:
Solve by substituting
-4 = 3x + 2
-2 -2
-6 = 3x
3x/3 = -6/3
x = -2
Answer:
x = -2
Step-by-step explanation:
So we are given the function f(x) = 3x + 2 and we are asked to find the value of x that makes f(x) = -4. To do this, we can replace f(x) with -4 in the given function and solve for x.
-4 = 3x + 2
Swap sides.
3x + 2 = -4
Subtract 2 from both sides.
3x = -6
Divide both sides by 3.
x = -2
So we have found that x = -2 when f(x) = -4. This means that when x = -2, f(x) = -4.

Gavin doubles it then adds 15 to get the answer 44.2 what was the original number
Answer:
14.6
Step-by-step explanation:
44.2 - 15 = 29.2
29.2 / 2 = 14.6
Answer:
14.6
Step-by-step explanation:
If you take 44.2 and subtract 15, you get 29.2. You would then just divide 29.2 by 2 to get the original number. You're literally doing the equation backward.

Gina's family goes to a theme park. The family pays a $12 fee to park their car and buys admission tickets for all 5 family members. Her family pays a total of $132 . Which equation can be used to solve for t , the price of one admission ticket?
A.
5(12+t)=132
B.
5t+12=132
C.
5(12)+t=132
D.
5+12+t=132
Answer:
B
Step-by-step explanation:
5t + 12 = 132
We know the price of parking and we know what they paid in total. There are 5 members with the unknown price.
Answer:
B
Step-by-step explanation:
You're trying to find how much a ticket, which is t. you need 5 tickets for the family, plus the twelve dollar fee which is there anyways for the car, and it add up to 132. subtract 12 from 132 and you get 120. 120 divided by 5 is 24. so 24 dollars for a ticket, but the equation you would need is 5t+12=132
