Which ratios are equivalent to 2:5?

1 answer:

7 0

Suppose the first number of the ratio is x and the second number is y. The current ratio is x:y. Now to solve the ratio, 5 divided by 2 equals 2.5 meaning the equation is 2.5x=y. Plug in any number to the x value and follow the equation and plug it into x:y to list all equivalent ratios.

What is <br> the ratio equal for 90:18

Ann [662]

To find the ratio between 2 numbers, you need to find the GCF of those 2 numbers. If the GCF is the ratio, the ratio is in it's simplest form.
GCF of 90 and 18 is 18
divide both numbers by the GCF and the final simplest ratio is 5:1

Cone B is the image of cone A after dilation by a scale factor of \frac{1}{2}

Bogdan [553]

The surface area of cone B is 10 km², and Cone B is the image of cone A after dilation by a scale factor of 1/2

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

Cone B is the image of cone A after dilation by a scale factor of 1/2, hence:

Surface area of cone B = 40 km² * (1/2)² = 10 km²

The surface area of cone B is 10 km², and Cone B is the image of cone A after dilation by a scale factor of 1/2

IM SORRY BUT I NEED THIS QUESTION TOO ASAP PLEASE

Paraphin [41]

Using proportions, it is found that the amount of the novel she would have read is:

D. 14/15.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.

She has finished 5/6 of the novel, and will have read more 1/10 in the next two days, hence the total amount read is given by:

$\frac{5}{6} + \frac{1}{10} = \frac{25 + 3}{30} = \frac{28}{30} = \frac{14}{15}$

Hence option D is correct.

Please help this is the last problem I need

tangare [24]

Answer:

$sin 54 = \frac{x}{14}$

Step-by-step explanation:

$sine = \frac{opposite}{hypotenuse}$

Side z is the adjacent, since it is next to the angle you are solving for.

Side x is the opposite, since it is opposite the angle you are solving for.

The side measuring 14 is the hypotenuse, since it is across from the right angle.

$sin 54 = \frac{x}{14}$
