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.

Answer:

the equation of the above is

y= 10x - 5

Answer:

a) 23 and 24

b) see step-by-step

c) 23.2

Step-by-step explanation:

a)  find the greatest square number below 540?

    find the smallest square number above 540?

23² = 529   and   24² = 576

    529 < 540 < 576

⇒ √529 < √540 < √576

⇒ 23 < √540 < 24

Hence, √540 lies between 23 and 24

b) **I'm not sure how accurate they want this, so I've added several options**

√540 = 23.23790008...

23.23790008... - 23 = 0.2379000772...

0.2379000772... = 2,379,000,772 / 10,000,000,000

Therefore, √540 = 23 and 2,379,000,772 / 10,000,000,000

Or 23 and 2,379 / 10,000

Or 23 and 24/100 = 23 and 6/25

Or 23 and 2/10 = 23 and 1/5

c) (√540)² = 540

So we are looking for a number whose square is 540.

We know that √540 lies between 23 and 24 (from part a), so let's start with 23.5:

   23.5² = 552.25

552.25 > 540 so try a smaller number

   23.3² = 542.89

542.89 > 540 so try a smaller number

  23.2² = 538.24

538.24 < 540

  23.24² = 540.0976

540.0976 > 540

So √540 lies between 23.2 and 23.24, therefore, the decimal approximation is 23.2 to the nearest tenth place

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.

Step-by-step explanation:

The total number of children's ticket bought is 28 - x

The total cost of adult's ticket is $30x.

The total cost of children's ticket is 420 - 15x.

The total cost of the tickets is 420 - 15x.

The total number of children's ticket = total ticket - adult ticket

28 - x

Cost of the adult's ticket = cost per ticket x total ticket bought

$30x

Cost of the children's ticket = cost per ticket x total ticket bought

$15 x (28 - x) = $420 - 15x

Total amount spent = $420 - 15x + 30x = $420 - 15x

Answer:

5.29

Step-by-step explanation:

1. Set up the equation 2.3x2.3 on top of eachother like so,

[tex]2.3\\ x2.3[/tex]

We will be working right to left.

2. Then we must create the first line of numbers.

a. Mulitply 3x3=9

b. Multiply 3x2=6

This makes the  first line of numbers 69.

3. For the second line of number do much of the same.

a. First add a zero under 9 to offset this new line.

b. Then multiply 2x3=6

c. Then 2x2=4

4. Finally add the two number together.

[tex]69+460=5.29[/tex]

5. Count up the decimal places in both factors combined, then moved the decimal sign left that many times.

This will result in our answer 5.29.

The exterior angle of the regular polygon is: 5°

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°

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 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
