Answer:  The length of the third straw is 29 centimeters.

Step-by-step explanation:  Given that Anja is creating a triangle using three straws and the lengths of two shorter straws are 20 cm and 21 cm.

We are to find the length of the third straw in centimeters so that Anja will create a right triangle.

The two shorter straws will make the legs of the right-angled triangle because they are shorter.

Since the third straw will be the largest, so it will make the HYPOTENUSE of the triangle.

In a right-angled triangle, we have

Hypotenuse² = length of one leg² + length of the other leg².

Therefore, we get

Hypotenuse^2=20^2+21^2=400+441=841\\\\\Rightarrow Hypotenuse=29.

Thus, the length of the third straw is 29 centimeters.

Fred bought 4 liters of liquid laundry detergent, 3,260 milliliters of fabric softener, and 2.3 liters of bleach. Select true or
Norma-Jean [14]

Answer:

1. False 2. False 3. True 4. False 5. True

Step-by-step explanation:

Given:

Fred bought 4 liters of liquid laundry detergent,

3,260 millilitres of fabric softener, and

2.3 liters of bleach.

Select true or false for each statement.

1. Fred bought 96 millilitres more fabric softener than bleach.

<u>Solution</u><u>:</u>

Fred bought fabric softener = 3,260 millilitres

Fred bought bleach = 2.3 liters = 2300 millilitres

1 liter = 1000 millilitres

2.3 liter = 1000 \times 2.3 = 2300 millilitres

Fred bought more fabric softer than bleach = 3,260 - 2300 = 960

Hence, it is false and actually Fred bought 960 millilitres more fabric softer than bleach.

2. Fred bought 1.95 liters more laundry detergent than bleach.

<u>Solution</u>:

Fred bought laundry detergent = 4 liters

Fred bought bleach = 2.3 liters

Fred bought more laundry detergent than bleach = 4 - 2.3 = 1.7 liters

Hence, it is false and actually Fred bought 1.7 liters more laundry detergent than bleach.

3. Fred bought 960 millilitres more fabric softener than bleach.

It is true, as solved above:

4. Fred bought 170 millilitres more laundry detergent than bleach.

<u>Solution</u>:

Solved above:

Fred bought 1.7 liters more laundry detergent than bleach.

1.7 liters = 1.7 \times 1000 = 1700 millilitres

1.7 liters = 1700 millilitres not 170 millilitres

Hence, it is false.

5. Fred bought 0.96 liters more fabric softener than bleach.

<u>Solution:</u>

Solved above:

Fred bought 960 millilitres more fabric softer than bleach.

1000 millilitres = 1 liters

1 millilitre = \frac{1}{1000}

960 millilitre =  \frac{1}{1000}\times960=\frac{960}{1000} =0.96\ liter

960 millilitres = 0.96 liter

Hence, it is true.

Use the discrimination and select whether the roots of 5x^2-4x+3=0 are real or non-real
Lelu [443]
With a=5, b= -4 and c=3, the discriminant is

16-4(5)(3) = 16-60, a negative number.  Thus, the roots are non-real (complex).
