rate = distance / time Ok, part a is correct, try writing the answer as 2/5

rate = 2/5 = 0.4 in/s

rate = 0.4 in/s

Hi, I'm here is just that the pictures are small, I'm trying to read them

Please upload a picture of part b like the last picture you sent of part a

2/5 = x/ 15

x = 15 x 2 / 5

x = 30/5

x = 6 inches

The result is 6

Which way shows one way you can decompose 15 to find 42 x 15?

soldier1979 [14.2K]

Answer:

42 * 10 + 42 * 5

which agrees with the third option (C) shown on the list of possible answers

Step-by-step explanation:

Notice that using distributive property we can write:

42 * 15 = 42 (10 + 5) = 42 * 10 + 42 * 5

which agrees with the third option (C) shown on the list of possible answers.

A map is laid out in the standard (x,y) coordinate plane. How long, in units, is an airplane's path on the map as the airplane f

xeze [42]

Answer:

Distance between the points A and B is 15.52 units.

Step-by-step explanation:

It has been given in the question that an airplane flies along a straight line from City A to City B.

Map has been laid out in the (x, y) coordinate plane and the coordinates of these cities are A(20, 14) and B(5, 10).

Distance between two points A'(x, y) and B'(x', y') is represented by the formula,

d = $\sqrt{(x-x')^{2}+(y-y')^{2}}$

So we plug in the values of (x, y) and (x', y') in the formula,

d = $\sqrt{(20-5)^{2}+(14-10)^{2}}$

d = $\sqrt{(15)^{2}+(4)^{2}}$

d = $\sqrt{225+16}$

d = 15.52

Therefore, distance between the points A and B is 15.52 units.

Charmaine drove to the mountains last weekend. There was heavy traffic on the way there, and the trip took 9 hours. When Charmai

iVinArrow [24]

To mountains took 9 Hrs at x mph where x = No of miles to mountains
No of miles travelled = 9x

From mountains took 4 hours at (x+40) mph
No of miles travelled = 4(x+40)

Therefore 9x=4(x+40) thus 9x=4x+160 thus x=32 = distance Charmaine lives from the mountains

Help urgent In a class of 35 students 15 of them have cats 16 have dogs 3 hangs none how many probability does have both

dalvyx [7]

Answer:

9/25

Step-by-step explanation:

Number of student who has cat , dog = 25 - 3 = 22

Number of students who has cat and dogs = (15 + 16) - 22

= 31 - 22 = 9

Number of students who has only cats = 15 - 9 = 6

Number of students who has only dogs = 16 - 9 = 7

P(Cat & dog) = 9/25
