Trudy is making a picture frame and needs nails that measure 0.375 inch at the hardware store nails that measure in fractions of
Evgen [1.6K]

Answer:

She should buy the nails that measure in fraction 375/1000 inch

Step-by-step explanation:

* Lets explain how to change the decimal number to fraction

- Write down the decimal divided by 1

- Multiply both top and bottom by 10 for every number right to the

 decimal point

- Simplify the fraction

- Ex: convert 0.65 to fraction

# 0.65/1

# Multiply up and down by 100 because there are two numbers

  right the decimal point (0.65)(100)/(1)(100) = 65/100

# Divided up and down by 5 to simplify it to 13/20

* <em>Lets solve the problem</em>

- Trudy is making a picture frame and needs nails that measure

 0.375 inch

- the hardware store nails that measure in fractions of an inch

  125/1,000 inch , 25/100 inch , 375/1,000 inch

- <em>Lets find which of them she should to buy</em>

∵ The decimal is 0.375

- Divide it by 1

∴ 0.375 = 0.375/1

∵ There are 3 number right to the decimal point

∴ Multiply up and down by 1000

∴ 0.375 = 375/1000

∴ She should buy the nails that measure in fraction 375/1000 inch

What is the value of a?
Kisachek [45]
The answer is 41.41
Since we know the side that is opposite to a, and the hypotenuse, we have enough information to get the cosine of a. The cosine is 45/60. If we know the cosine of an angle, we can get the arccos of that value to get the angle. The arccos of 45/60 is about 41.41.

A waitress sold 17 ribeye steak dinners and 16 grilled salmon​ dinners, totaling ​$571.16 on a particular day. another day she s
avanturin [10]
Let x = ribeye steak cost, y = grilled salmon cost. With this we set up two equations:

17x + 16y = 571.16
21x + 8y = 583.22

We must now pick which dinner we could like to find the cost of first. I choose the ribeyes. To do so, I'm going to divide the first equation by - 2. I will explain why:

- 8.5x - 8y = - 285.58
21x + 8y = 571.16

Now we combine like terms. Notice that the y-variables cancel each other out. This why I divided by - 2. It causes this cancellation leaving us with only one variable to solve. This gives us:

12.5x = 297.64

Divide both sides by 12.5 to isolate variable x.

x = 23.8112 or x ≈ 23.81. I round two decimal points since we're dealing with money. 

Now, we plug this cost into either of the two equations and solve for variable y. I'll use the first one.

17(23.81) + 16y = 571.16
404.77 + 16y = 571.16

Subtract 404.77 from both sides to isolate the variable and its coefficient. 

16y = 166.37

Divide by 16 on both sides to get rid of the coefficient

y ≈ 10.3993 or y ≈ 10.40 since we're dealing with money. 

Cost of ribeye steak -- $23.81
Cost of grilled salmon -- $10.40
