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

* Lets solve the problem

- 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

- Lets find which of them she should to buy

∵ 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

Mrs. Lin is sewing costumes for her grandchildren. She is making three lion costumes, one zebra costume, and two bear costumes.

stepladder [879]

Answer:

$12\frac{1}{8}\ yd$

Step-by-step explanation:

we know that

The total fabric that Mrs. Lin needs is equal to

$3(1\frac{2}{3})+2\frac{5}{8}+2(2\frac{1}{4})$

Convert mixed number to an improper fraction

$1\frac{2}{3}=1+\frac{2}{3}=\frac{5}{3}$

$2\frac{5}{8}=2+\frac{5}{8}=\frac{21}{8}$

$2\frac{1}{4}=2+\frac{1}{4}=\frac{9}{4}$

substitute

$3(\frac{5}{3})+\frac{21}{8}+2(\frac{9}{4})$

$5+\frac{21}{8}+\frac{9}{2}$

$\frac{40+21+36}{8}=\frac{97}{8}\ yd$

Convert to mixed number

$\frac{97}{8}\ yd= \frac{96}{8}+\frac{1}{8}=12\frac{1}{8}\ yd$

What is cos (x)? A) 48/58 B) 58/48 C) 26/58 D) 58/26

arsen [322]

Remark
In order to solve for the Cos(x), you need to find the missing side. You can do that by finding the Sin(x) first and then the Cos of x or you can just use the Pythagorean theorem. I'm going to do the latter.

Formula
a^2 + b^2 = c^2

Givens
a = ???
b = 32
c = 58

Sub and solve
a^2 = ???
b^2 = 1024
c^2 = 3364

a^2 + 32^2 = 58^2
1024 + a^2 = 3364 Subtract 1024 from both sides.
a^2 = 3364 - 1024
a^2 = 2340 Take the square root of both sides.
sqrt(a^2) = sqrt(2340) Break a into its prime factors.
a = sqrt(2 * 2 * 5 * 3 * 3 * 13)

Rule
For every pair of equal factors, one can be brought outside the root sign and the other is discarded.
a = 2 * 3 * sqrt(5*13)
a = 6 sqrt(65)

The cos of an angle = opposite / hypotenuse.
Cos(x) = 6*sqrt(65) / 58 <<<<< This should be the answer
If you are offered choices, you should list them

Another choice would be 6*8.0623 / 58 = 0.8340 <<<<< Answer
