Daniel worked for 213213 hours and earned $18.20. How much would he make if he worked for 514514 hours? Enter your answer in the box.

Answers

Answer 1
Answer: convert the hours to improper fractions

2 and 1/3 hours=2+1/3=6/3+1/3=7/3
5 and 1/4=5+1/4=20/4+1/4=21/4

ratio and proprtion
time/pay=(7/3)/18.2
if work 21/4 hours how much is pay
(7/3)/18.2=(21/4)/pay
times both sides by 18.2pay aka cross multiply
(7/3)pay=(21/4)18.2
(7/3)pay=382.2/4
times both sides by (3/7) to clear fraction (7/3 times 3/7=21/21=1)
pay=1146.6/28
pay=40.95

will earn $40.95 in 5 and 1/4 hours

Answer:

1. ∠A and ∠B are right angles.                      Given

2. m∠A = m∠ B                                               All right angles are congruent.

3. ∠BEC≅ ∠AED                                              Vertical angles are congruent

4. ΔCBE ~ ΔDAE                                               AA

Step-by-step explanation:

A proof always begins with the givens.

1. ∠A and ∠B are right angles. -------------->Given

2. m∠A = m∠ B  are equal since----------->  All right angles are congruent.

3. ∠BEC≅ ∠AED  are also equal since---->Vertical angles are congruent

4. ΔCBE ~ ΔDAE since two angles are equal----------> AA

a geologist had two rocks on a scale that weighed 2 1/2 pounds together rock A weighed a total of 1/7 of the weight how much did rock A weigh

Answers

Answer:

Let A and B be the two rocks.

As per the statement: a geologist had two rocks on a scale that weighed 2 1/2 pounds together rock

⇒Total weight of rock (A+B) = 2(1)/(2) pounds

or

A+B= (5)/(2)

Also, it is given A weighed a total of (1)/(7) of the weight.

A = (1)/(7) * (\text{Total weight})

then;

A = (1)/(7) * (5)/(2) = (5)/(14)

Therefore, (5)/(14) pounds did rock A weight.

It is already given in the question that the combined weight of two rocks is  2 /1/2 pounds. The weight of rock A is also known and it is 1/7 of the total weight of the two rocks. This is enough to find the desired solution.
Now
Total weight of the two rocks = 2 1/2 pounds
                                               = 5/2 pounds
Then
Weight of Rock A = (5/2)/(1/7) pounds
                             = (5 * 7)/2 pounds
                             = 35/2 pounds
                             17 1/2 pounds
So Rock A weighs 17 1/2 pounds. This is the weight of Rock A and it is only required for this question. If you are eager to find the weight of rock B then you have to subtract the weight of Rock A form the total weight of the two rocks.
