It says “ Marco is riding his bicycle at a speed of 16 kilometers per hour. How far will he ride in 2.5 hours at this speed?”

Answer: true

Step-by-step explanation:

Answer:

164.48 or 164.5

Step-by-step explanation:

So, to make it simpler, you can do the circle like this: 3.14×(8×8). Then you can work down!

3.14 × 64

200.96

and then because it's halved, you divide by 2

100.48

then that's the half circle

The square would just be 8×8=64

then add the circle and the square and viola!

164.48

Answer:

30

Step-by-step explanation:

15=30

x=60

cross multiply

30×x=60×15

30x=900

x=30

so Judah rides his bike 30 miles in one hour

Answer:

30 miles

Step-by-step explanation:

multiply 15 miles by 2 and 1/2 by 2 to get 30 miles an hour.

Answer:

C. x=23

Step-by-step explanation:

180=(5x+11)+54

Answer:  40 mm

===============================================================

Explanation:

I'm assuming your teacher used pi = 3.14 to compute the circumference.

If so, then,

C = 2*pi*r

251.2 = 2*3.14*r

251.2 = 6.28r

6.28r = 251.2

r = (251.2)/(6.28)

r = 40 mm is the radius

Answer:

9

Step-by-step explanation:

i hope this helps!

Answer: 9

Step-by-step explanation:

If we add 10 plus 3 that equals 13 and then we multiply that by 7 because of the pemdas rule that equals 91. then we subtract 91 by 82 and that equals 9.

Hope This Helps! :P

This is a triangular prism

Answer:

about $1148.06

Step-by-step explanation:

Your goal is to find the area of the island of grass and multiply that area by the cost per square yard.

Area = radius * radius * pi

You are told that the diameter = 15 yards. We also know that the radius that we need is half of the diameter. Radius = 7.5 yards.

This means that the Area = 7.5 * 7.5 * 3.14 = 176.625 square yards

Then we multiply by the cost per square yard:

176.625 * 6.50 = 1148.06 is your answer

Hi there! Before we start with your problem. Recall the Trigonometric Function of (-x) first.

Now what we need to do is to imagine a unit circle. We know that angle (-x) rotate clockwise while (x) rotates counterclockwise.

Now imagine if it rotates clockwise, it:d start at the fourth quadrant first. That means the y-value is negative while x-value is positive.

We also know that (x, y) = (cos, sin)

Now move to the 2(pi)/3.

[tex] \large{ \frac{2 \pi}{ 3} = \frac{2(180)}{3} \longrightarrow 2(60)= \boxed{120 \degree}}[/tex]

Thus, the value of 2pi/3 is 120°

Now imagine again. In a unit circle, 120° is in second quadrant if we rotate counterclockwise. But if we rotate clockwise, where would the 120° be? Remember that (-x) rotates clockwise. That's right! (-120°) is in the third quadrant. In the third quadrant, cos is negative there along with sin.

So we can conclude that:

120° is also a reference angle of 60° because of 180°-60° = 120°

Thus,

[tex] \large{cos( - \frac{2 \pi}{3} )= cos( - 120 \degree) = cos(120 \degree) \longrightarrow - \frac{1}{2} }[/tex]

2. 10/7 or 1 3/7

3. 13/5 miles or 2.6 miles

4. 4

5. 18/7 or 2 4/7

6. 10

7. 9 muffins

8. 81 feet

9. 27 flowers

Step-by-step explanation:

1. 4 1/5 • 2 2/3 = 28/5 or 5 3/5

2. 2 6/7 • 2 1/4 = 10/7

3. 3 1/4 • 4/5 = 13/5

4. 6 • 2/3 = 4

5. 2/7 • 9 = 28/7

6. 5/6 • 12 = 10

7. 24 • 3/8 = 9

8. 27 • 3 = 81 (multiply 27 by 3)

9. 45 • 3/5 = 27

I hope this helps, good luck! ;D

BTW I feel your pain, I really wish you the best of luck!

Answer:

11

Step-by-step explanation:

32.5 divided by 5 = 6.5

71.5 divided by 6.5 = 11

the answer is 11

Answer:

11 tickets

Step-by-step explanation:

Divide $32.50 by 5 to find the price per ticket

Divide $71.50 by $6.50 (the ticket cost) to get the number of tickets that can be bought with $71.50

Hope this helps :)

Answer:

The answer will be A) A'(4,3)

Step-by-step explanation:

90 degrees will send the rectangle to Quadrant 1, the rectangle itself has also been rotated so by rotating the rectangle 90 degrees and putting it in place for quadrant 1, it should give you the answer.

(You can also rotate the image)

Answer:

where is the picture of the table?

Step-by-step explanation:

Answer:

bottom left is 1:30

Step-by-step explanation:

Answer:

Area = 25 square units

Step-by-step explanation:

Parallelogram : b =(6 - 1) = 5  h, = 2

Rectangle : length= (8 - 3) = 5units, width= (5 - 2) = 3 units

Area of Parallelogram = b x h = 5 x 2 = 10

Area of Rectangle = Length x Breadth = 5 x 3 = 15

Total Area = 10 + 15 = 25 square unit

Answer:

352 cm

Step-by-step explanation:

The circumference of a circle is given by the radius times 2 times π:

2•56•3,14 = 351,68 ≈ 352 cm
