There are 4 white and 8 red roses in a bouquet. Find the ratios. The ratio of the number of red roses to the number of white roses
Given:
Number of white roses = 4
Number of red roses = 8
To find:
The ratio of the number of red roses to the number of white roses.
Solution:
Using the given information, the ratio of the number of red roses to the number of white roses is
[tex]\text{Required ratio}=\dfrac{\text{Number of red roses}}{\text{Number of white roses}}[/tex]
[tex]\text{Required ratio}=\dfrac{8}{4}[/tex]
[tex]\text{Required ratio}=\dfrac{2}{1}[/tex]
[tex]\text{Required ratio}=2:1[/tex]
Therefore, the required ratio is 2:1.
A seven digit telephone number is of the form ABC-DEFG. In one particular state, the digit ‘A' is restricted to any number between 1 and 9. The digits B and C are restricted to any number between 2 and 9. The digits D,E,F, and G have no restriction. How many seven digit phone numbers are possible with these restrictions?
Answer:
2,520,000
Step-by-step explanation:
We are told the telephone number has seven digits of the form ABC-DEFG
We are told that the digit ‘A' is restricted to any number between 1 and 9.
Between 1 and 9 means numbers in between 1 and 9. So 1 and 9 are not included.
This means the numbers include 2, 3, 4, 5, 6, 7, 8. Which means there are 7 ways to select.
We are also told that digits B and C are restricted to any number between 2 and 9
This means that the numbers are; 3, 4, 5, 6, 7, 8. It means there are 6 ways to select.
Now, we are told that digits D,E,F, and G have no restriction. Thus, there are 10 ways to select each digit.
To find the Number of seven digit phone numbers that are possible with these restrictions, we will multiply each individual number of ways for each digit.
Thus;
Probability = 7 × 6 × 6 × 10 × 10 × 10 × 10 = 2,520,000

Every Sunday, Nathan and his friends get together to play their favorite board game, The
Gems of Rawumba. Whoever collects the most gems wins! Players can earn gems by building
mines.
There is a proportional relationship between the number of mines Nathan builds, x, and the
number of gems he earns, y.
Answer: 2 gems per mine
Step-by-step explanation:
Solve 10/5 to find the constant in this question. The answer will be 2.The constant of proportionality if, There is a proportional relationship between the number of mines Nathan builds, x, and the number of gems he earns, y, is 2 gems per mine.
What is proportionality?
When the corresponding elements of two numerical sequences, frequently experimental data, have a fixed ratio, this is referred to as the coefficient of proportionality, and the two sequences are said to be proportional or directly proportional.
Given:
There is a proportional relationship between the number of mines Nathan builds, x, and the number of gems he earns, y,
Values of x = 5, 6, 7, 10
Values of y = 10, 12, 14, 20
Calculate the constant of proportionality as shown below,
The constant of proportionality = y / x
The constant of proportionality = 10 / 5
The constant of proportionality = 2 gems per mine.

Paul,Linda,and Aaron make homemade cards. Paul can make 1 card for every 3 cards Linda makes. Linda can make 3 cards for every 2 cards that Aaron makes. During the week,Aaron makes 72 cards. How many more cards does Linda make than Paul during the week?
Answer:
Linda makes 72 more cards than Paul
during the week
Step-by-step explanation:
Here, we want to know how many cards Linda makes than Paul during the week.
We proceed as follows;
From the question;
If Paul makes 1 card, then Linda has made three
Now let’s get their relationship with Aaron;
If Aaron makes 2 cards , Linda has made three
Now since Aaron made 72 cards, Let’s say Linda has made x cards
Let’s get the value of x now
To get the value of x, we simply cross multiply;
2 - 3
72 - x
2 * x = 3 * 72
x = (3 * 72)/2 = 108 cards
Now recall , for every 3 cards of Linda, Paul made only 1;
So the number of cards Paul will make if Linda makes 108 will be 108/3 = 36
So the number of more cards that Linda makes than Paul during the week will be ; 108 -36 = 72 cards

Which number is a multiple of 6?
A) 50
B) 44
C) 26
D) 36
Answer:
D
Step-by-step explanation: 36 is in the 6 times table
Answer: 36
Step-by-step explanation: To find the multiples of 6, we multiply 6 by
all the whole numbers until we find our answer listed.
6 × 0 = 6
6 × 1 = 6
6 × 2 = 12
6 × 3 = 18
6 × 4 = 24
6 × 5 = 30
6 × 6 = 36
Notice that 36 s a multiple of 6.
So 36 is our answer.

Is the number 7.787887888... a rational number ?
Answer: No, it is not rational (it is irrational)
If we had something like 7.78787878... where the "78"s go on forever, then it would be rational. This is called a repeating decimal.
Something like 7.787887888... does not have a repeating pattern. It has 7's and 8's, but the number of 8's seems to increase by 1 each time you list a 7. So this is why the given number is not rational.
2/9 of the members are boys in a community service club. if there are 95 more girls than boys, how many girls are there in club?
Answer:
133 girls
Step-by-step explanation:
Total members = x
Number of boys = [tex]\frac{2}{9}x[/tex]
Number of girls = [tex]\frac{2}{9}x +95[/tex]
Number of boys + Number of girls = total members
[tex]\frac{2}{9}x+\frac{2}{9}x+95=x\\\\\frac{2}{9}x+\frac{2}{9}x=x -95\\\\\frac{2}{9}x+\frac{2}{9}x-x=-95\\\\\frac{4}{9}x-x = -95\\\\\frac{4}{9}x-\frac{9}{9}x = -95\\\\\frac{-5}{9}x=-95\\\\x = -95*\frac{9}{-5}\\\\x=19*9[/tex]
x = 171
Number of boys = [tex]\frac{2}{9}*171[/tex] = 2 * 19 = 38
Number of girls = 38 + 95 = 133
Solve the literal equation for y.
2x+5y = 3y+8
Answer:
y = -x +4
Step-by-step explanation:
2x+5y = 3y+8
Subtract 3y from each side
2x+5y-3y = 3y-3y+8
2x+2y = 8
Subtract 2x from each side
2x+2y -2x = -2x+8
2y = -2x+8
Divide by 2
2y/2 = -2x/2 +8/2
y = -x +4

-3x+15-6x=30+32x
Answer:
-15/41
Step-by-step explanation:
-3x + 15 - 6x = 30 + 32x
~Combine like terms
-9x + 15 = 30 + 32x
~Subtract 15 to both sides
-9x = 15 + 32x
~Subtract 32x to both sides
-41x = 15
~Divide -41 to both sides
x = -15/41
Best of Luck!
Answer:
-15/41 = x
Step-by-step explanation:
-3x+15-6x=30+32x
Combine like terms
-9x+15 = 30 +32x
Add 9x to each side
-9x+15+9x = 30+32x+9x
15 = 30+41x
Subtract 30 from each side
15-30 = 30+41x-30
-15 =41x
Divide each side by 41
-15/41 = x
A new fitness center had 350 members in its first year. The number of members increased by 14% each year there after. Find the approximate number of years it will take to gain 1000 members.
Answer:
14 years Will give you 1036 members
Step-by-step explanation:
Set it up as an equation
x/350 = 14/100
100x = 4900
100x/100 = 4900/100
x = 49
49 x 14 = 686
686 + 350 =1036

Answer:

The energy is recycled after flowing through ecosystems is not true, So option b is the correct answer.
The energy flow in the ecosystem is one of the most important factors for the survival of such a large number of organisms.
What is an ecosystem?An ecosystem consists of all the organisms and the physical environment with which they interact. The ecosystem has two main components which are biotic and abiotic. They are connected through nutrient cycles and energy.
From the sunlight as a source of energy, it enters the system through photosynthesis. So, the energy is transferred between organisms. energy flows take place through the food chain and food web, which is not recycled in ecosystems and requires a continuous input of energy to sustain. Thus, the energy flow is unidirectional.
Therefore, b is the correct option that energy is recycled after flowing through ecosystems.
