Answer:

x = 12°

Step-by-step explanation:

The measures of the exterior angles of a hexagon are x°, 2x°, 5x°, 6x°, 7x°, and 9x°. Solve for x.

The sum of the exterior angles of a polygon sums up to 360

An hexagon is a 6 - sided polygon

(x + 2x + 5x + 6x + 7x + 9x) = 360

30x = 360

Divide both sides by 30

x = 360 / 30

x = 12

Hence, x = 12°

Answer:

18.86 m

Step-by-step explanation:

From the given question, both covers the same distance of the straight line segment.

For the inner lane,

length of arc of its semicircle = [tex]\pi[/tex]r

                                   = 30 x [tex]\frac{22}{7}[/tex]

                                   = 94.2857

So that,

the total length for the two halves of the inner lane = 2 x 94.2857

                                                                  = 188.5714 m

For the outer lane,

length of arc of its semicircle = [tex]\pi[/tex]r

                                                 = 33 x [tex]\frac{22}{7}[/tex]

                                                 = 103.7143

The total length for the two halves of the outer lane = 2 x 103.7143

                                                                  = 207.4286 m

The difference between the two = 207.4286 - 188.5714

                                                       = 18.8572 m

Therefore, Devin would run 18.86 m more to complete one lap.

Answer:

(2,8), (3,5),

Step-by-step explanation:

Answer:

y=0.25x-1

Step-by-step explanation:

y=mx+b

slope = 0.25

y = 0.25x+b

the y intercept = -1

y = 0.25x+-1

y = 0.25x-1

Answer:

Yes, he can buy it for $350 or less

Step-by-step explanation:

330.00 x 4.5%

330.00 x 0.045 = 14.85

330.00 + 14.85 = 344.85

or

330.00 x 1.045  = 344.85

Answer:

Step-by-step explanation:

The length 0.51 miles and 0.47 miles are the distances from each observer to the sailboat.

The Law of Sines (also called the Sine Rule) is defined as it relates all three sides of a triangle with an angle of a triangle.

Triangle is a basic polygonal shape of a triangle that has three sides and three interior angles. It is one of the fundamental shapes in geometry.

As per the given question, the given data  as:

A = 63

B = 56

C = 61 (because these angles should add up to 180)

c = 1/2

We know that the Sine Rule,

sin 63 / a = sin 61 / .5

a = 0.51 miles

sin 56 / b = sin 61 / .5

b = 0.47 miles

Therefore, the length 0.51 miles and 0.47 miles are the distances from each observer to the sailboat.

Answer:

2 and [tex]\frac{8}{5}[/tex]

Step-by-step explanation:

when you divide by a fraction you just multiply by its reciprocal

[tex]\frac{2}{3}[/tex] ÷ [tex]\frac{1}{3}[/tex] = [tex]\frac{2}{3} * \frac{3}{1}[/tex]

then just solve

[tex]\frac{6}{3}=2[/tex]

for the second one do the same thing

[tex]\frac{4}{5} * \frac{2}{1} =\frac{8}{5}[/tex]

Answer:

Step-by-step explanation:

According to Triangle Inequality Property:

Measurement of any two sides of the triangle should be greater than the third side

So,

For 2.5,

6 + 4 = 10 > 2.5

4 + 2.5 = 6.5 > 6

6 + 2.5 = 8.5 > 4

For 4,

6 + 4 = 10 > 4

4 + 6 = 10 > 4

4 + 4 = 8 > 6

While for 1 and 2,

4 + 1 = 5 < 6

and

4 + 2 = 6 = 6

Hence,

Only 2.5 and 4 are the possible measurements.

Hi there!

[tex]\large\boxed{h = \frac{15x}{y}}[/tex]

Recall the volume of a pyramid is:

V = 1/3(bh)

We are given the volume and side length of the base. Find the area of the base:

A = s²

A = (5xy²)² = 25x²y⁴

Plug in the solved for base:

125x³y³ = 1/3(25x²y⁴)h

To isolate for h, begin by multiplying both sides by 3:

375x³y³ = (25x²y⁴)h

Divide both sides by 25x²y⁴. Use the following exponent property:

xᵃ / xᵇ = xᵃ⁻ᵇ

Thus:

375x³y³ / 25x²4⁴ = 15x/y.

The height must be equal to:

[tex]h = \frac{15x}{y}[/tex]

Answer:

44 cm³

Step-by-step explanation:

If you break up this shape into 2 pieces you get a rectangle with the measurements of 2, 2, and 5 and another rectangle with the measurements of 2, 2, and 6. You then multiply 2, 2, and 5 together which will get you 20, and multiply 2, 2, and 6 together which will get you 24. You will then add both products which will get you 44. Since the measurement is in centimeters and it is a 3 dimensional shape it will then become 44 cm³.

Answer:

72.5°

Step-by-step explanation:

180° is a straight line. Subtract 35° from 180°, you get 145°, now divide 145° by 2, you will get 72.5°.

Hope this helped.

The sum of all angles is 360

we have one angle given which is 35 degrees the angle infront of it is also the same as opposite angles are always equal

so x= 35

for y as said earlier opposite angels are equal so the empty 2 angles are also y

so now we have

[tex]4y+35+35=360\\4y+70=360\\4y=290\\y= 72.5[/tex]

so y=72.5 degrees

Answer: a is 16, b is -8

Step-by-step explanation:

3a-45=3

add 45 to both sides to get rid of -45

3a=48

divide both sides by 3

a = 16

plug 16 into the first equation

16 + b = 8

subtract 16 from both sides

b = -8

is it good for the elimination method? hmm i probably wouldn't use it in this case since there aren't any variables to cancel out.

Answer:

x = Total distance from your home to school = 1,500 meters

Step-by-step explanation:

Let

x = Total distance from your home to school

When you walked 20% of the way to school, you still have 1200 meters more to walk

Walked distance = 20% of x

= 20/100 * x

= 0.2 * x

= 0.2x

Total distance - walked distance = 1200 meters

x - 0.2x = 1200

0.8x = 1200

x = 1200 / 0.8

x = 1,500 meters

x = Total distance from your home to school = 1,500 meters

Answer:

24 pints

Step-by-step explanation:

128 ounces · 3 = 384 ounces

384/16 = 24 pints

Answer:

There are 16 ounces in a pint. 128 ounces will then be 128/16, or 8 pints. If you use three of the 128 ounces, or 8 pints, you can multiply the 8 by 3, giving 24 pints.

Answer:

It will be Fourth of July in 7 weeks.

Step-by-step explanation:

Since you know that there are seven days in a week, you can use a rule of three to find the amount of weeks in 49 days that is the number of days until Fourth of July:

 7 days    →    1 week

49 days    →        x

x=(49*1)/7

x=7

According to this, the answer is that it will be Fourth of July in 7 weeks.
