A cheetah ran 300 feet in 2.92 seconds. What was the cheetah’s average speed in miles per hour? Show your work.
alexdok [17]

Answer:

about 70.0 mph

Step-by-step explanation:

speed = distance/time

(300 ft)/(2.92 s)·(1 mi)/(5280 ft)·(3600 s)/(1 h) = (300·3600/(2.92·5280)) mi/h

≈ 70.0498 mi/h

Find the largest positive integer that will divide 542, 436, 398 leaving reminders 7, 11, 15 respectively
saveliy_v [14]

Answer:

17

Step-by-step explanation:

Here in this question for finding the numbers that will divide 398, 436 and 542 leaving remainder 7, 11 and 15 respectively we have to first subtract the remainder of the following. By this step we find the highest common factor of the numbers.

And then the required number is the HCF of the following numbers that are formed when the remainder are subtracted from them.

Clearly, the required number is the HCF of the numbers 398−7=391,436−11=425, and, 542−15=527

We will find the HCF of 391, 425 and 527 by prime factorization method.

391=17×23425=52×17527=17×31

Hence, HCF of 391, 4250 and 527 is 17 because the greatest common factor from all the numbers is 17 only.

So we can say that the largest number that will divide 398, 436 and 542 leaving remainders 7, 11 and 15 respectively is 17.

Note: - whenever we face such a type of question the key concept for solving this question is whenever in the question it is asking about the largest number it divides. You should always think about the highest common factor i.e. HCF. we have to subtract remainder because you have to find a factor that means it should be perfectly divisible so to make divisible we subtract remainder. because remainder is the extra number so on subtracting remainder it becomes divisible.

A circular playground for a daycare center is to be covered with square tiles that are 9 inches on each side. The circle has a d
nydimaria [60]

Answer:

9 boxes

Step-by-step explanation:

Area=\pi r^{2}

Since 1 ft= 12 inches then with diameter of 12 ft, radius becomes 6 ft and converted to inches it's 6*12=72 in

Area=\pi\times 72^{2}=16286.01632  in^{2}

Area of 1 tile= 9*9=81

Number of tiles= \frac {16286.01632
}{81}=201.0619298
\202 tiles

Number of boxes= 202/25=8.08 boxes hence 9 boxes

Find the area of the smaller sector.<br> Round to the nearest tenth.
Tema [17]

Answer:73. 0

Step-by-step explanation:

Radius=8.02

Tita =130

Area of sector = tita/360 x πr^2

130/360 x 22/7 x (8.02) ^2

130/360 x 22/7 x64. 3204

= 72.99

To the nearest tenth = 73.0
