Answer:

45 people

Step-by-step explanation:

3/5 x 75 = 45, therefore, 45 people out of 75 preferred rice to noodles.

Answer:

45 prefer rice out of 75 surveyed.

Step-by-step explanation:

75 divided by 5 is 15. 15 x 3 = 45!

3/5 = 45/75

Answer:

It has exactly 3 congruent sides.

Step-by-step explanation:

Since ∠FGJ = ∠JGH = 30° and GJ is a perpendicular bisector of FH, ∠GJF = 90°. So in ΔFGJ, ∠FGJ + ∠GJF  + ∠GFJ = 180°.

So, 30° + 90° + ∠GFJ = 180°

120° + ∠GFJ = 180°

∠GFJ = 180° - 120°

∠GFJ = 60°

Also, since GJ is the perpendicular bisector of FH, ∠GJH = 90°. So in ΔJGH, ∠JGH + ∠GJH  + ∠JHG = 180°.

So, 30° + 90° + ∠JHG = 180°

120° + ∠JHG = 180°

∠JHG = 180° - 120°

∠JHG = 60°

Since ∠FGH = ∠FGJ + ∠JGH = 30° + 30° = 60°

Since ∠FGH = ∠GFJ = ∠JHG = 60°

So, ΔFGJ is an equilateral triangle. Since all its angles are equal, so also, all its sides are equal. So, ΔFGJ is congruent by SSS and AAA so its 3 sides are congruent.

So exactly 3 sides are congruent in ΔFGJ.

Answer:

It has exactly 3 congruent sides

Answer:

he swims 0.9 kilometers each day.

Step-by-step explanation:

Answer:

He swims 0.9km each day.

Step-by-step explanation:

To convert m to km divide by 1000

900/1000 =0.9

Answer:

He is watching TV for 2 hours and 40 minutes.

Step-by-step explanation:

We are given that the episodes of a TV program are each 40 minutes long. Phill watches four episodes together.

As it is stated that the length of each episode of a TV program is 40 minutes, so the length of four episodes is given by;

1 episode = 40 minutes

4 episodes = 4 [tex]\times[/tex] 40

                  = 160 minutes

So, the length of four episodes together is 160 minutes.

Now, we have to convert the time in hours and minutes;

As we know that 1 hour = 60 minutes

160 minutes = 120 minutes + 40 minutes

                    = 2 hours + 40 minutes

Hence, the length of four episodes together is 2 hours and 40 minutes.

c. they are all parts of 12, and when added together they equal 11/12. The formula to solve non proportionate fractions*or with different denominators* is to CROSS multiply and make the denominators equal, then add the numerators and SIMPLIFY.

*Cross multiply to make the denominator equal (you can google how to make fractions equal)

then add the numerators together

then simplify. PLEASE BE CONSIDERATE OF THE FORMULA AND DONT BE INTIMIDATED BY THE LOOK OF THE PROBLEM. They all have the same formula or method of solving. Good Luck!! I hope this helps.

The expression which has an equivalent sum of 11/12 is 1/12 + 5/12 + 5/12

check all options:

a. 10/22 + 2/12

The lowest common multiple of 22 and 12 is 264

= (120 + 44) / 264

= 164/264

divide through by 4

= 41 / 66

b. 5/4+3/4+3/4

The lowest common multiple 4 is 4

= (5+3+3) / 4

= 11/4

c. 1/12+5/12+5/12

The lowest common multiple of 12 is 12

= (1+5+5) / 12

= 11/12

d. 5/6+6/6

The lowest common multiple of 6 is 6

= (5+6) / 6

= 11/6

Therefore, the expression which has an equivalent sum of 11/12 is 1/12 + 5/12 + 5/12

Answer:

15÷4÷1/6.

first of all change ÷ to ×.

which will be 15×1/4×6/1.

which will be 15×1/2×3.

which is 15×3=45/2.

the answer is 22.5 or 22 whole number 1/2.

15 divided by 4 and 1/6 is equal to 18/5 or 3 and 3/5.

To divide 15 by 4 and 1/6, we can convert the mixed number 4 and 1/6 into an improper fraction.

4 and 1/6 can be written as (4 x 6 + 1) / 6 = 25/6.

Now, we can divide 15 by 25/6:

15 ÷ (25/6) = 15 x (6/25)

= (15 x 6) / 25

= 90/25.

Now, the fraction 90/25 can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 5:

= 90/25

= (90 ÷ 5) / (25 ÷ 5)

= 18/5.

Therefore, 15 divided by 4 and 1/6 is equal to 18/5 or 3 and 3/5.

Answer: C. 21.2d+12.4f

Step-by-step explanation:

Given, The width of a rectangle measures[tex](5.5d+9.7f)[/tex]  centimeters, and its length measures [tex](5.1d-3.5f)[/tex] centimeters.  

Perimeter of rectangle = 2 (length + breadth)

[tex]= 2 ((5.5d+9.7f)+ (5.1d-3.5f) )\\\\=2 (5.5d+9.7f+5.1d-3.5f)\\\\= 2(5.5d+5.1d+9.7f-3.5f)\ \ \ [\text{Combine like terms}]\\\\= 2(10.6d+6.2f)\\\\= 21.2d+12.4f\ \ \ [\text{Multiply 2 inside the bracket}][/tex]

Hence, the correct option is C. 21.2d+12.4f .

Answer:

An expression for the area of the rectangle if the width is w inches is

[tex]A =[/tex] 3w

when the width is 1 inch, Area = 3 square inches (in²)

when the width is 2 inches, Area = 6 square inches (in²)

when the width is 3 inches, Area = 9 square inches (in²)

when the width is 26 inches, Area = 78 square inches (in²)

Step-by-step explanation:

The area of a rectangle is given by

[tex]A = l[/tex] × [tex]w[/tex]

Where [tex]A[/tex] is the area of the rectangle

[tex]l[/tex] is the length of the rectangle

and [tex]w[/tex] is the width of the rectangle

From the question,

length, [tex]l[/tex] = 3 inches

width, [tex]w[/tex] = w inches

Hence, An expression for the area of the rectangle is

[tex]A =[/tex] 3 × w

[tex]A =[/tex] 3w

Now, to find the area of the rectangle when the width is 1, 2 , 3, and 26 inches

1. when the width is 1 inch (That is [tex]w[/tex]  = 1 inch)

Then, [tex]A =[/tex] 3w

[tex]A =[/tex] 3 × 1

[tex]A =[/tex] 3 square inches (in²)

2. when the width is 2 inches (That is [tex]w[/tex]  = 2 inches)

Then, [tex]A =[/tex] 3w

[tex]A =[/tex] 3 × 2

[tex]A =[/tex] 6 square inches (in²)

3. when the width is 3 inches (That is [tex]w[/tex]  = 3 inches)

Then, [tex]A =[/tex] 3w

[tex]A =[/tex] 3 × 3

[tex]A =[/tex] 9 square inches (in²)

4. when the width is 26 inches (That is [tex]w[/tex]  = 26 inches)

Then, [tex]A =[/tex] 3w

[tex]A =[/tex] 3 × 26

[tex]A =[/tex] 78 square inches (in²)

Answer:

2a² = c²

Step-by-step explanation:

Right triangles follow the Pythagorean Theorem, a² + b² = c². The hypotenuse (c) must be the longest of the sides. In the given triangle, both legs measure a units. So, a = b. Therefore, we have a² + a² = c² or 2a² = c².

The equation can be used to determine if the triangle is a right triangle is c² = 2a².

The relationship between the three sides of a right-angled triangle is explained by the Pythagoras theorem, commonly known as the Pythagorean theorem. The Pythagorean theorem states that the square of a triangle's hypotenuse is equal to the sum of its other two sides' squares.

The well-known Pythagorean Theorem states that the square on the hypotenuse of a right triangle equals the sum of the squares on its legs.

The longest side measures c units.

The other sides of the triangle measure a units.

As, we know that longest side is the Hypotenuse.

Using the Pythagorean Theorem

H² = P² + B²

c² = a² + a²

c² = 2a²

So, the Correct statement is c² = 2a².
