An ironwoman race involves 3 swim legs and a beach run back to the start as shown in the figure.
What is the total distance covered in the race?

Answer:

Option 3

Step-by-step explanation:

y=3+x is a straight line that runs through y=3 and x=-3

So your 3rd option here is the one.

Answer:

I think it's the third option

Answer:

x=32/5

Step-by-step explanation:

x/8=4/5

x=(4/5)×8

x=32/5

Answer:

D

Step-by-step explanation:

There you go mate, just writing this to be 20 words long so I can answer it

Answer:

7 x 4 = 28

28 x 1/2(dividing by 2) = 14, 14 x 2(two triangles) = 28

4 x 5 = 20(area of square in the middle)

5 x 8 = 40(area of square on one side), 40 x 2 = 80(area of squares on both sides)

Now lets add the given areas:

28 + 20 + 80 = 128 square is your answer.

Answer:

B) 40

Step-by-step explanation:

Angle X and the missing angle inside the triangle are equal as the are opposite angles.

Therefore,

180 - 65 - 75 = 40

Answer:

No it's not compulsory.

Step-by-step explanation:

If the ratio of sides are given then that can also help you find angle. Not only that if the relationship between the perpendicular and base are given then you can find angle

E.g.

if the ratios of the sides is 5:4:3 then you can find the angle

Answer:each box cost =$3

Step-by-step explanation:

Amount of money Ms Hart has to spent on costume boxes=$40

Amount gotten as change after purchase=$4

Amount actually used up buying costume boxes =$40-$4=36

Since she bought 12 boxes , each box cost =$36/ 12=$3

Answer:

20 ways

Step-by-step explanation:

Because You can get a 2nd place and 3rd place medal so thats 2 ways but there are 10 races so times 10 is 20 :)))))

Answer:

Company B

Step-by-step explanation:

Given

See attachment for graph

Required

Company with the least additional fee

This means the y-intercept and it represents the flat fee

To get the y-intercept, we simply write out the point where [tex]x= 0[/tex]

From the graph of A, we have:

[tex](x,y) = (0,70)[/tex]

Additional Charges = 70

From the table of B, we have:

[tex](x,y) = (0,50)[/tex]

Additional Charges = 50

From the equation of C, we have:

[tex]y=10x+ 90[/tex]

[tex]y(0) = 10 * 0 + 90[/tex]

[tex]y(0) =0 + 90[/tex]

[tex]y(0) =90[/tex]

Additional Charges = 90

By comparison. company B has the least additional fee because: [tex]50 < 70 < 90[/tex]

Answer:

A = $70753

Step-by-step explanation:

[tex]A = P(1 + \frac{r}{n})^{nt}[/tex]

P = $41000

r = 6.25% = 0.0625

n = 1

t = 9

[tex]A = 41000(1 + 0.0625)^9 = 70752.91[/tex]

[tex]A = \$70753[/tex]

Answer:

Y=Asin[B(x-c)] + D

B=2π/T

=2π/(n/4)

=8π/n

Y=6sin(8πx/n)

Answer:

12.56

Step-by-step explanation:

use the circumference of a circle formula, C=2πr, to find the circumference

so C=2π(2)=12.56 the last one

Step-by-step explanation:

Volume=mass

volume

Answer: yes they are

Step-by-step explanation: the way you know is because the angles on each shape are the same and the lines on the shapes are the same length. If one shape is bigger than another or if one has a different shape than the other, they are not congruent. I hope that helped you!

Answer:

4 1/11 hours

Step-by-step explanation:

Tom can paint 1/6 of the fence in an hour

Huck can paint 1/5 of the fence in an hour

Tom takes a half-hour break; we can create this equation:

1/6x - 1/2 + 1/5x = 1

use a denominator of 30:

5x/30 - 15/30 + 6x/30 = 30/30

11x/30 = 45/30

multiply each side by 30/11 to get:

x = 45/11 or 4 1/11

Answer:

2.8km

Step-by-step explanation:

a = sqrt(c^2-b^2)

a = sqrt(9.9^2 - 9.5^2)

a = sqrt(7.76)

a = 2.78567765544

Round that to 2.8 and there's your answer

Answer:

[tex]\theta = 0, \frac{\pi}{2}, \pi,...[/tex]

Step-by-step explanation:

[tex]sin\theta + cos \theta = 1 \\\\squaring both the sides\\\\sin^{2}\theta + cos^{2}\theta+2 sin\theta cos\theta = 1 \\\\2sin\theta cos\theta = 0 \\\\sin2\theta = 0\\\\2\theta = 0, \pi, 2 \pi,....\\\\\theta = 0, \frac{\pi}{2}, \pi,...[/tex]

This is the correct solution.

Answer:

720° :)

Step-by-step explanation:

You can find the total interior angle for any shape using the following (n being the number of sides):

S = ( n - 2 ) × 180 °

S = (6-2) * 180

S = 720
