There are 425 vegetables at a farmers market stand. Of the vegetables, 125 of them are carrots. What is the ratio of the number of carrots to the number of other vegetables at the stand?

Answers

Answer:

the ratio of the number of carrots to the number of other vegetables is  25 : 12

Step-by-step explanation:

The computation is shown below:

Given that

Total vegetables = 425

Out of which 125 vegetables represent carrot

the other vegatables should be

= 425 - 125

= 300

Now the ratio of the number of carrots to the number of other vegetables is

= 125 : 300

= 25 : 12

Hence, the ratio of the number of carrots to the number of other vegetables is  25 : 12

Five out of eight birds that visited the feeder ate the birdseed. If 60 birds ate the birdseed today, how many birds visited the feeder?

Answers

Answer:

Therefore, the birds visited the feeder = 96

Step-by-step explanation:

Five out of eight birds that visited the feeder ate the birdseed.

i.e. the ration is: 5/8

Given that 60 birds ate the birdseed today.

Note that if we multiply '5' by '12', we get the number 60.

Now, all we need to is to also multiply '8' by '12' to maintain the initial ratio which is 5/8.

i.e. (5×12) / (8×12) = 60/96

Therefore, the birds visited the feeder = 96

Ally's tricycle has two different wheel sizes: one larger wheel and two smaller wheels. As Ally travels the distance between her house and her neighbor's house on the tricycle, the larger wheel revolves 10 times and each of the smaller wheels revolve 25 times. If half the circumference of the larger wheel is 5 inches more than the circumference of one of the smaller wheels, what is the distance, in inches, traveled by the tricycle between Ally's house and her neighbor's house?

Answers

Answer:

500 inches

Step-by-step explanation:

Let C₁ and n₁ be the circumference and the number of rotations of the larger wheel. Also, let C₂ and n₂ be the circumference and the number of rotations of the smaller wheel. Since the distance moved by both wheels from Ally's house to her neighbor's house is the same, n₁C₁ = n₂C₂. (1)

Also it is given that half the circumference of the larger wheel is 5 inches more than the circumference of one of the smaller wheels.

So, C₁/2 = C₂ + 5

C₁ = 2(C₂ + 5)  (2)

Substituting C₁ into (1), we have

n₁C₁ = n₂C₂.

n₁[2(C₂ + 5)] = n₂C₂.

Since n₁ = 10 and n₂ = 25, we have

10[2(C₂ + 5)] = 25C₂

20(C₂ + 5) = 25C₂

expanding the bracket,

20C₂ + 100 = 25C₂

collecting like terms, we have

25C₂ - 20C₂ = 100

5C₂ = 100

dividing both sides by 5, we have

C₂ = 100/5

= 20 inches

So, the distance between Ally's house and her neighbor's house is d = n₂C₂ = 25(20)

= 500 inches

The distance travelled by Ally's tricycle is [tex]500inches[/tex]

Let

[tex]d=\text{the distance between Ally's house and her neighbor's house}\\C_b=\text{the circumference of the larger wheel}\\C_s=\text{the circumference of each of the smaller wheels}[/tex]

Then, from the question

[tex]d=10C_b=25C_s\\\\\frac{C_b}{2}=C_s+5[/tex]

Eliminating [tex]C_s[/tex] from the second statement, we get

[tex]\frac{C_b}{2}=5+\frac{2C_b}{5}[/tex]

Solving for [tex]C_b[/tex],

[tex]C_b=50inches[/tex]

To calculate the distance travelled between her house and her neighbor's house,

[tex]d=10C_b\\\implies d=10\times 50inches=500 inches[/tex]

Therefore, the distance travelled between Ally's house and her neighbor's house is [tex]500inches[/tex]

Michael baked 60 oatmeal cookies and 45 chocolate chip cookies to package in plastic containers for her friends at school. She wants to divide the cookies into identical containers so that each container has the same number of each kind of cookie. If she wants each container to have the greatestnumber of cookies possible, how many plastic containers does she need?

(I really need help)

Answers

Answer:

3

Step-by-step explanation:

Michael must find the smallest number possible that can divide 60 and 45 then take the two quotients after dividing the 2 types of cookies by the smallest number possible.

2 is not possible as 45 is an odd number

3 can divide both 60 and 45

60/3 = 20 oatmeal cookies in each container.

45/3 = 15 chocolate chip cookies in each container.

Grape juice has 180 containers.

Step-by-step explanation:

Given that the ratio of containers of orange juice to containers of grape juice in a store is 5 orange juices to 4 grape juices.

i.e.

Orange Juice containers : Grape Juice containers = 5 : 4

Total containers = 405

It means if we divide 405 by 9, we get the 9 equal parts of 45.

i.e. 405 / 9 = 45

as

Orange Juice containers : Grape Juice containers = 5 : 4

It means the share of Grape Juice containers is 4 parts out of 9 parts.

Thus, multiply 45 by 4 to determine the number of containers grape juice have:

45 × 4 =  180 containers

Therefore, grape juice has 180 containers.
