A bowl contains blueberries and strawberries there are a total of 20 bares in the bowl the ratio blueberries to strawberries is
Alexus [3.1K]

Answer:

16 blueberries and 4 strawberries

Step-by-step explanation:

Given:

A bowl contains blueberries and strawberries there are a total of 20 berries in the bowl.

The ratio blueberries to strawberries is 4 to 1

Question asked:

How many of each berry are in the bowl ?

Solution:

Ratio of blueberries and strawberries = 4 : 1

Let ratio be x

Number of  blueberries in the bowl = 4x

Number of strawberries in the bowl = 1x=x

As total berries in the bowl are 20 and the bowl contains both blueberries and strawberries in the ratio 4 : 1 :-

4x+x=20\\5x=20\\

Dividing both sides by 5

x=4

Number of strawberries in the bowl = x = 4

Number of  blueberries in the bowl = 4x = 4\times4=16

Thus, there are 16 blueberries and 4 strawberries in the bowl.

Melissa is planning a rectangular vegetable garden with a square patch for tomatoes
astra-53 [7]

The expressions for the length and the width of the rectangular garden are <u>3x + 2 feet</u>, and <u>x + 5 feet</u> respectively where x is the length of the square patch for tomatoes.

A square is a quadrilateral with all four sides equal, and all four angles at 90°, whereas a rectangle is a quadrilateral with opposite pair of sides equal, and all four angles at 90°.

In the question, we are informed that Melissa is planning a rectangular vegetable garden with a square patch for tomatoes.

The side of the square is given to be x feet.

We are asked to write expressions for the length and width of the rectangular garden.

For the length of the rectangle:-

We are informed that she wants the length of the garden to exceed three times the length of the tomato patch by 2 feet.

Thus, the length of the garden can be shown as the expression <u>3x + 2 feet</u>.

For the width of the rectangle:-

We are informed that she also wants the garden's width to exceed the width of the tomato patch by 5 feet.

Thus, the width of the garden can be shown as the expression <u>x + 5 feet</u>.

Thus, the expressions for the length and the width of the rectangular garden are <u>3x + 2 feet</u>, and <u>x + 5 feet</u> respectively where x is the length of the square patch for tomatoes.

The value of y in the triangle is 6°.

<h3>How to calculate the value of y in the triangle?</h3>

Firstly, it's important to note that a triangle has the total angles of 180°.

Based on the information, the triangle has interior angle measures of 11y, 10y + 10°, and 10y - 16º.

The value of y in the triangle will be illustrated thus:

11y + 10y + 10 + 10y - 16 = 180

31y - 6 = 180

31y = 180 + 6.

31y = 186

Divide.

y = 186 / 31

y = 6

The value of y is 6.
