what are the common denominators for 1/4 and 2/5 in pairs of fraction, plz help

Answer:

right 50:30 left

divide both sides by a common factor. (I've used 10 hcf)

right 5:3 left

Answer:

Step-by-step explanation:

Table

Time            3       6       9        12    

Rainfall        2       4       6         8

Time is on the x axis

Rainfall is on the y axis

Slope = (y2 - y1)/(x2 - x1)

Slope = (8 - 2) /(12 - 3)

Slope = 6/9 = 2/3

Unit rainfall = 2 cm rainfall / 3  hours = 0.667 cm rainfall / hour.

Answer:

30 on the first one 5x6=30, the 2nd one is 5 and the 3 one is 10 chickens

Answer:

1. Zack has 6 times more seeds than Ben, if Ben has 5 seeds, just multiply how many seeds Ben has by 6, which means Zack planted 30 seeds (This can be written Z=B*6, where Z is how many seeds Zack has, and B is how many seeds Ben has)

2.  If there are a total of 40 cards divided into 8 groups of students, that means that each group got 5 card (40 ÷ 8 = 5)

3. If each chicken has 2 wings, and she has a total of 20 wings, that means that she bought a total of 10 chickens (20 ÷ 2 = 10)

Answer:

b = [tex]\sqrt{45}[/tex]

Step-by-step explanation:

Using Pythagoras' identity in the right triangle on the left.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

b² + 6² = 9²

b² + 36 = 81 ( subtract 36 from both sides )

b² = 45 ( take the square root of both sides )

b = [tex]\sqrt{45}[/tex]

Answer:

5 to 4

Step-by-step explanation:

when it's asking for a ratio it's basically division

chocolate/vanilla = 40/32 = 5/4

5/4 is the same as 5:4 or 5 to 4

Answer:

You have 12.25 minutes left to workout.

Step-by-step explanation:

Marked down 15% means the new price would be 85% of the original price ( 100%-15% - 85%)

Multiply the original price by 85%:

5250 x 0.85 = 4462.50

The new price is $4,462.50

Answer:

$8.75

Step-by-step explanation:

Tiffany allowance is reduced by $1.25 each time she forgets to clean her room

If she forgets to clean her room 7 times this month

Then her allowance is reduced by

= 1.25 × 7

= 8.75

Hence Tifanny allowance is reduced by $8.75

Answer:

Hence Tifanny allowance is reduced by $8.75

Answer:

8/15 kg of food daily

Step-by-step explanation:

Bo feeds his dog twice a day. In the morning, he feeds the dog 1/3 kg of dog food. In the evening, he feeds the dog 2/10 kg of food.

The total kilograms of food that Bo feed his dog is calculated as:

Number of kilograms fed in the morning + Number of kilograms fed in evening

= 1/3 kg + 2/10kg

The Lowest Common Denominator = 30

= 10 + 6/30

= 16/30

= 8/15 kg

Therefore, Bo feeds his dog 8/15kg of food daily.

Answer:

Both fractions are less than 1/2

​ 1/2 kg

Answer:

the answer for your question will be -3

Step-by-step explanation:

x+8=5. -3+8=5,.

Answer:

3

Step-by-step explanation:

You have to move 8 to the other side of the equation.

So the equation becomes 8 - 5 = x

8 - 5 = x

Therefore 3  =  x

Answer: D: Quadratic Equation.

Step-by-step explanation:

y = a*x^2 + b*x + c is a polynomial of degree = 2, this is also called a quadratic equation (because the largest exponent is 2)

Then the correct option is D: Quadratic Equation​

The other options are used for:

A: Subtraction:

This is for the difference between two numbers, a subtraction is X - Y.

B: Quotient:

This is for a division between two numbers, the quotient between X and Y is:

X/Y.

C: Scientific Notation:

This is used to simplify the notation of numbers with a lot of digits. Instead of write numbers like:

13,000,000

We can just write this as:

1.3*10^7

Answer:

Step-by-step explanation:

umm... thanks for the points????????

Step-by-step explanation:

Answer:

Option (4)

Step-by-step explanation:

From the picture attached,

ΔABC is a right triangle.

Since, inscribed angle in a semicircle is always a right angle, Hypotenuse AC will be the diameter of the circle.

Length of diameter AC = 58 ft

Radius of the circle = [tex]\frac{58}{2}=29[/tex] ft

Area of the circular garden = πr² [r = radius of the circle]

                                             = π(29)²

                                             = 2642.08 ft²

Area of the right triangle = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]

                                          = [tex]\frac{1}{2}(27)(50)[/tex]

                                          = 675 ft²

Area of the of the region covered with grass = Area of the circular garden - Area of the right triangle

= 2642.08 - 675

= 1967.08 ft²

≈ 1966 [Nearest value]

Option (4) will be the answer.

Answer:

  y = -5x³

Step-by-step explanation:

The point of inflection of the parent cubic function f(x) = x³ is at the origin, the same place it is shown on the graph. So, there is no translation involved in creating the graph.

We know the parent function gives f(1) = 1, but here, we have (x, y) = (1, -5). This suggests a vertical scale factor of -5. So, the transformed function is ...

  y = -5x³

Answer:

0.315

Step-by-step explanation:

10256/32548 is about 0.3151 (I used calculator)

0.3151 rounded to thousandth place is 0.315

Remember the rule when round, 5 and above, up, below 5, stay the same.

The number after 5 in 0.3151 is 1 and 1 is less than 5, so the 5 stays the same.
