Michelle is planting flowers in her garden. She wants the ratio of daisies to carnations to be 3 to 2. Michelle wants to plant a total of 30 flowers. How many daisies should she plant?

Answers

She should plant 18 daisies and 12 carnations.

Steps:

Divide 30 by 5 because 3+2 is 5

The answer is 6

The proportion for daisy is 3 so multiply 3 by 6 which is 18

For carnations multiply 2 by 6

Answer:

18 Daisies and 12 Carnations

Step-by-step explanation:

The total amount of flowers adds to be 30 therefore the amount of daises plus the amount of carnations should equal 30 (d+c=30). Then your ratio of daises to carnations is 3 to 2. Which means that you are going to have three daisies for every 2 carnations.

Find the value of x
Please help

Answers

Answer:

x=67

Step-by-step explanation:

Two ways to solve it:

1st way: Just looking at it, x is definitely not 180° because it’s to big of an angle, it is definitely not 113° because it’s still to big of an angle, and it’s also not 90° because it doesn’t form a right angle. So it must be 67°.

2nd way: Since two angles in a straight line add up to 180°, you can subtract 113° from 180° to find what x is. You can tell that 180° - 113° is equal to 67°

So either way, the answer is: x=67

Hope this helped! :)

a piece of wire is 28cm in length is cut into two parts, each part bend to make a square. given that area of square is 416m^2. find the perimeter of each square.

Answers

Answer:

25.488 cm and 2.512 cm

Step-by-step explanation:

Note: the area of squares is 41 cm² but not 416 m², typo

Let the sides of squares be x and y

Based on given we have equations:

4x + 4y = 28x² + y² = 41

Simplify the first equation

4x + 4y = 28x + y = 7x = 7 - y

Substitute x to solve for y:

(7 - y)² + y² = 4149 - 14y + y² + y² = 412y² - 14y + 49 - 41 = 02y² - 14y + 8 = 0y² -7y + 4 =0

Solving we get:

y= 6.372 cm or y= 0.628cm

Then

x = 0.628 cm or x = 6.372 cm

Perimeter of each square is:

4*6.372 = 25.488 cm

and

4*0.628 = 2.512 cm

Kiran says that a solution to the equation `x-7=3` must also be a solution to the equation `3x-21=9`.

Write a convincing explanation as to why this is true. Explain how these are equivalent equations.

Answers

Answer: This is true because everything in the first equation was multiplied equally to get to the second equation. Every part was multiplied by three. The first equation is x-7=3 and the second can be seen as 3(x-7=3). The three will not affect x seeing that the entire equation had the same thing done to it.

The perimeter of a rectangle is 40 cm. The length is 14 cm.
Let x = width of the rectangle.

Ravi says he can find the width using the equation 2(x + 14) = 40.
Fran says she can find the width using the equation 2x + 28 = 40.

Answer the questions to solve the equations and to compare the steps and solutions.

1. Which of these is the most helpful first step for solving Ravi's equation, 2(x + 14) = 40?
