Sheena purchased 12 meters of cloth. She used 3 7/9 meters of cloth for curtains and 2 4/7 for a bed sheet. How much cloth does she have left

Answers

Answer: Sheena has 5 41/73 meters of cloth left.

Step-by-step explanation:

First, add 3 7/9 and 2/47 to add them follow these steps:

Convert any mixed numbers to fractions,

3 7/9 = 34/9  

2 4/7 = 18/7

Next: Multiply the new fractions,

(34 x 7) + (18 x 9)

         9 x 7  

After multiplying, solve the new problem,

238 + 162    

     63

Your new fraction should be,

400/63

Convert 400/63 to a mixed number, which is 6 22/63.

After that subtract 12 - 6 22/63.

To find the answer, you do the same thing.

Convert any mixed numbers to fraction

12 = 12/1

6 22/63 = 400/63

Then multiply the fraction,

(12 x 63) - (400 x 1)

          1 x 63

After multiplying, solve your new problem,

756 - 400

     63

Your new fraction should be,

356/63

Convert t356/63 into a mixed number, which is 5 41/63

So, your answer should be 5 41/63.

a support wire to a newly planted tree makes a 32° angle with the ground.
determine the angle made by the wire at the point of contact to the tree by finding the complement of 32°

Answers

Answer:

58°

Step-by-step explanation:

Since the angle made by wire with ground and at the point of contact to the tree are complementary.

So,

Required angle = 90° - measure of the angle formed by wire with ground

Required angle = 90° - 32° = 58°

find x. round to nearest hundredth. PLS HELP. will award brainliest

Answers

Answer:

[tex]x[/tex] = 29.64 to the nearest hundredth

Step-by-step explanation:

The three sides of a right-angled triangle have specific names:

The hypotenuse (H) is the longest side. It is opposite the right angle.The opposite side (O) is opposite the angle in question.The adjacent side (A) is next to the angle in question.

The 3 trigonometric ratios are:

[tex]sin(\theta)=\frac{O}{H} \\\\cos(\theta)=\frac{A}{H} \\\\tan(\theta)=\frac{O}{A}[/tex]

For the given triangle we are given the angle and the side that is OPPOSITE to the angle, and need to find the hypotenuse.

Therefore, we would use the trig ratio:  [tex]sin(\theta)=\frac{O}{H}[/tex]

Substituting the values from the triangle:  [tex]sin(35)=\frac{17}{x}[/tex]

Multiply both sides by [tex]x[/tex]:  [tex]xsin(35)=17[/tex]

Divide both sides by [tex]sin(35)[/tex]:  [tex]x=\frac{17}{sin(35)}[/tex]

Therefore, [tex]x[/tex] = 29.63859553...

So [tex]x[/tex] = 29.64 to the nearest hundredth

Ann and her friends are visiting chocolate shops in Hampton. They take a cab from one chocolate shop to another. On a map, the two are separated by 1.5 inches. The scale of the map is 3 inches = 5.2 miles. In real life, what is the distance between the two chocolate shops?

Answers

Answer:

Ann and her friends traveled 2.6 miles to go to another chocolate shop in the cab.

Step-by-step explanation:

As we know, that 1.5 is half of 3. And to understand that better. Let's do this

1.5--> 15

3-->30

30-15=15. So, 15 (1.5), is half of 30. (3)

We know that 3 inches on the map equals 5.2 miles, and if we have to basically find the half of 5.2 to get the answer, then, let's do this.

5.2÷2=2.6

So, hence, 2.6 miles is our answer.

One interior angle of a regular polygon is 175 degrees. What is the measure of one exterior angle?​

Answers

The exterior angle of the regular polygon is: 5°

What is an Interior Angle of a Regular Polygon?

Each interior angle of a regular polygon = (n - 2)180/n

Given:

interior angle = 175°

Thus:

175 = (n - 2)180/n

175n = 180n - 360

175n - 180n = -360

-5n = -360

n = 72

Thus,

Measure of one exterior angle = 360/72 = 5°
