Answer:

47) D 48) A 49) D

Step-by-step explanation:

47) (p + 3) x (8 - p) Multiply the sum of a number and 3 by the difference of 8 and a number.

48) -29 is less than -21 and the park ranger station, at -21 ft, is at a higher elevation than the park visitor center, at -29 ft.

49) The number of adult dogs is 17. The number of puppies is 8. The total number of dogs is 25. The only correct answer is D) The ratio of puppies to all dogs at the park is 8:25.

Spring flowering bulbs are on sale at austin's garden shop. Travis and sydney want to buy equal amounts of all four kinds. What

Answer:

Step-by-step explanation:

The problem will be solved by looking for the least common multiple (LCM) of the amounts of all four kinds since they want equal amounts of each.

LCM is defined as the smallest positive integer that is divisible by each of the integers (spring flowering bulbs in this case) involved in the operation.

therefore, we are looking for the LCM of the following integers:

Crocus: 6

Tulip: 4

Daffodil: 3

Hyacinth: 5

The first step to calculate the LCM is to factor each integer (to break it up into numbers that can be multiplied together to get the original number) and express them in terms of powers:

Crocus: 6=2*3

Tulip: 4=2*2= $2^{2}$

Daffodil 3 = 3 (prime numbers only have themselves as factors)

Hyacinth 5=5 (prime numbers only have themselves as factors)

Now, To calculate the LCM we need to multiply all factors we have found ( in this case 2, 3, and 5) but only once and with the maximum power.

$LCM=2^{2} *3*5=4*3*5=60$
