A polar bear swims 390 meters at a constant rate in 150 seconds. what is the speed of the polar bear?

1 answer:

5 0

The answer is 2.6 m/s

The speed (v) is distance (d) through time (t).
v = d/t

We know:
d = 390 m
t = 150 s

v = d/t
v = 390 m / 150s
v = = 2.6 m/s

Answer:

A = 8, B = 9 and C = 6.

Step-by-step explanation:

We can create equations to solve this:

6 + A = 14

So A = 8.

A + B = 17

8 + B = 17

B = 9.

C = 29 - (6 + A + B)

= 29 - ( 6 + 8 + 9)

= 29 - 23

= 6.

An acre measures 4840 square yards. In a city a lot on which a single family house can be built measures 40 feet across and 100

maw [93]

We are required to find the percent of an acres is this lot

The percent of acres of the lot is 27.55%

Area of an acre = 4840 square yards

Area of the lot = Length × width

= 40 feet × 100 feet

= 4000 square feet

convert feet to yards

1 foot = 0.333333

4000 square feet = 1333.333 square yards

Therefore,

Area of the lot = 1333.333 square yards

percent of an acres is this lot = 1333.333 / 4840 × 100

= 0.2754820247933 × 100

= 27.548202479338

Approximately,

27.55%

Therefore,

The percent of acres of the lot is 27.55%

The ratio of students who prefer pineapple to students who prefer kiwi is 12 to 5. Which pair of equivalent ratios could be used

AlexFokin [52]

Answer:

105 students could prefer kiwi if there are 357 total students.

Step-by-step explanation:

Given:

The ratio of students who prefer pineapple to students who prefer kiwi is 12 to 5.

Now, to find number of students prefer kiwi if there are 357 total students.

Let the students prefer pineapple be $12x.$

And the students prefer kiwi be $5x.$

Total students = 357.

So, we set an equation to get the number of students who prefer kiwi.

According to question:

$12x+5x=357$

$17x=357$

Dividing both sides by 17 we get:

$x=21.$

Thus, students prefer kiwi are:

$5x$

$=5\times 21=105.$

Therefore, 105 students could prefer kiwi if there are 357 total students.
