Answer:

11. D. May 20

12. C. Every 70 bags

Step-by-step explanation:

11.

Mark on the calendar what days she has swimming and what days she has diving. (See picture below) Red is Swimming and blue is diving. For swimming, count by 5s. For diving, count by 3s. Find the next square that has both red and blue on it.

Therefore, she has both swimming and diving lessons on May 20th.

12.

Use least common multiples.

Count by 7s and 10s until there is a number that's the same.

2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22....... You do not need to count by 2s. This is because you need to have a number that can also be counted to by 10s (a number with 10 as its factor), and 2 reaches all the multiples of 10. It is like 10 already includes 2.

7, 14, 21, 28, 35, 42, 49, 56, 63, 70

10, 20, 30, 40, 50, 60, 70

Therefore, every 70 bags will have all three items.

The top of the cylindrical can shown below has a diameter of 7 centimeters (cm).
Sidana [21]

Answer:

Circumference of the can is 21.98 cm.

Step-by-step explanation:

Since, top of the cylinder can shown in the figure is in the shape of a circle

Circumference of a circle is given by the formula,

Circumference 'C' = π × Diameter

Where r = radius of the circle

Therefore, circumference of a circle with diameter 7 centimeters will be,

C = 7π

   = 7 × 3.14

   = 21.98 cm

Therefore, circumference of the can is 21.98 cm.

Flying against the wind, a jet travels 2190 miles in 3 hours. Flying with the wind, the same jet travels 9520 miles in 8 hours.
dezoksy [38]

Answer:

Velocity of jet in still air is 970 miles per hour and velocity of wind is 210 miles per hour.

Step-by-step explanation:

Jet's velocity against wind is

3040/4 = 760 miles per hour and flying with wind it is

8260/7 = 1180 miles per hour.

Let the velocity of jet in still air be x miles per hour and velocity of wind be y miles per hour.

As such its velocity against wind is x − y and with wind is x + y and therefore

x − y = 760 and x + y = 1180

Adding the two 2 x = 1940 and x = 970 and y = 1180 − 970 = 210

Hence velocity of jet in still air is 970 miles per hour and velocity of wind is

210 miles per hour.
