Maria can stuff envelopes twice as fast as her friend James. Together they can stuff 6750 envelopes in 4.5 hours. How long would it take each of them working alone? Which of the following equations could be used to solve this problem?
Answers
I thinks it's the last one
hope this helps
Answer:
B. 4.5/t + 4.5/(2t) = 1Step-by-step explanation:
Work = rate*timeMaria's rate = 6750/tJames's rate = 6750/2tTheir rate when working together:
6750/t + 6750/(2t) = 6750/4.5 ⇒ 1/t + 1/(2t) = 1/4.5 ⇒4.5/t + 4.5/(2t) = 1Correct choice is B

What is the solution to |2x-8|<2?
Answers
Answer:
A) 3<x<5
Step-by-step explanation:
Given: |2x-8|<2
Make two inequalities:
First inequality:
2x-8<2
2x<10
x<5
Second inequality:
2x-8>-2
2x>6
x>3
Therefore, your solution is 3<x<5 since the two inequalities pass each other, making an "and" inequality.

If you are trying to build credit by using a credit card, each time you make a purchase with the credit card, deduct that amount from your checking account. That way, when your credit card bill is due, you will have enough to pay the credit card off in full. Kathy Lehner is going to start doing this. She plans on paying her credit card bill in full this month. How much does she owe with a 6% APR and the following transactions? (Round your answer to the nearest cent.)
31-day billing cycle
10/1 Previous balance $ 1,164
10/3 Credit $ 79 cr.
10/12 Charge: King Soopers $ 148
10/15 Payment $ 310 cr.
10/25 Charge: Delta $ 321
10/30 Charge: Holiday Fun $ 61
What would be the amount owed?
Answers
Answer:

Step-by-step explanation:
tell me if this hepls
Ur should be noted that Kathy Lehner owes approximately $1,311.97.
How to calculate the amountPrevious balance (10/1): $1,164
Credit (10/3): $79 credit. This reduces the balance, so the new balance is $1,164 - $79 = $1,085.
Charge: King Soopers (10/12): $148 charge. This increases the balance, so the new balance is $1,085 + $148 = $1,233.
Payment (10/15): $310 credit. This reduces the balance, so the new balance is $1,233 - $310 = $923.
Charge: Delta (10/25): $321 charge. This increases the balance, so the new balance is $923 + $321 = $1,244.
Charge: Holiday Fun (10/30): $61 charge. This increases the balance, so the new balance is $1,244 + $61 = $1,305.
Interest calculation: $1,305 * (6% * (31/365)) = $6.9698 (rounded to the nearest cent, which is $6.97).
Finally, to determine the total amount owed, we add the balance and the interest:
Total amount owed: $1,305 + $6.97 = $1,311.97
Therefore, Kathy Lehner owes approximately $1,311.97.

In an isosceles triangle, angle B is 40 degrees, and angle E is 2x+4. What is x?
Answers
Answer:
x = 40°
Step-by-step explanation:
In order to answer this problem, you will need to know the definition of an isosceles triangle.
An Isosceles triangle is specified as a triangle with 2 of its 3 sides having equal lengths.
Step 1: Draw your triangle.
Since 2 of your 3 sides are equal length and the primary angle measures 100°, you are dealing with an obtuse triangle or, properly named, a obtuse isosceles triangle.
Step 2: Label your angles inside of your triangle.
Remember that the sum of the angles inside of a triangle must add up to equal 180°.
Since we know the triangle we are dealing with in this problem, we can label our unknown angles 'x'.
Caution: The above statement ONLY applies to this type of triangle.
Step 3: Write an equation.
100° + x° + x° = 180°
Step 4: Solve for x.
100° + x° + x° = 180°
100° + 2x° = 180°
2x = 80°
x = 40°
a) Hace diez años las edades de Juan y Diego sumaban 36 años. Ahora Juan tiene el triple de la edad de Diego. ¿Cuál es la edad de cada uno ahora?
Answers
Answer:
Juan: 42
Diego: 14
Step-by-step explanation:
(d - 10) + (j - 10) = 36
d + j -20 = 36
d + j = 56
j = 3d
d + 3d = 4d = 56
d = 56/4 = 14
j = 3d = 3(14) = 42
