Circle any equivalent ratios from the list below.

marysya [2.9K]

Answer:

Equivalent ratios: we can that the first ratio is equivalent to the second, then third ratio is equivalent to the forth.

Ratio: 1: 2 Value of the Ratio: 1/2

Ratio: 5: 10 Value of the Ratio: 1/2

Ratio: 6: 16 Value of the Ratio: 3/8

Ratio: 12: 32 Value of the Ratio: 3/8

We notice that if the values are equivalent the ratios are equivalent

Step-by-step explanation:

Equivalent ratios:

To get if ratios are equivalent we look for the constant between ratios

a.Ratio: 1: 2 and Ratio: 5: 10

We apply the method of comparing the first term of both ratios , and the second term of both ratios. We see the constant is 5 ( 1/5 is equal to 2/10)

We do the same with third and forth ratio

Ratio: 6: 16 compare to Ratio: 12: 32

6/12 is equal to 16/32 the constant is 2

So, we can that the first ratio is equivalent to the second, then, third ratio is equivalent to the forth.

Value of the Ratio: The value is a ratio written as a fraction.

Ratio: 1: 2 Value of the Ratio: 1/2

Ratio: 5: 10 Value of the Ratio: 5/10 if we divide both sides by 5, we can say Value of the Ratio: 1/2

Ratio: 6: 16 Value of the Ratio: 6/16 if we divide both sides by 2, we can say the value is 3/ 8

Ratio: 12: 32 Value of the Ratio: 12/32 if we divide both sides by 4, we can say the value is 3/ 8

If the values are equivalent the ratios are equivalent.

Question 7: Find the value of x. The numbers below are in degrees. 140 S 50 20

Lyrx [107]

Given:

A figure.

To find:

The value of x.

Solution:

Draw two parallel lines as shown in the below figure.

If a transversal line intersect two parallel lines, then alternate interior angles are same.

$a=20$ (Alternate interior angle)

$d=b$ (Alternate interior angle) ...(i)

The value of angle d is

$d=50-a$

$d=50-20$

$d=30$

Using (i), we get

$b=30$

If a transversal line intersect two parallel lines, then same sides interior angles are supplementary angles.

$c+140=180$

$c=180-140$

$c=40$

Now,

$x=b+c$

$x=30+40$

$x=70$

Therefore, the value of x is 70.

Jessica decided to use 15% of her gross income for her down payment for a house. She makes 48,960.00 per year. How much money di

babymother [125]

Answer:

$Down\ payment = 7,344$

Step-by-step explanation:

Let x be the amount of 15% of gross income.

Given:

Jessica gross income = 48,960.00

She decided to use 15% amount as down payment.

We need to find the amount of 15% of gross income.

Solution:

Using percentage formula.

$percentage = (\frac{Value}{Total\ value})\times 100$

Now we substitute 15 in the place of percentage and 48,960 in the place of Total value.

$15=(\frac{x}{48960})\times 100$

Now, we apply cross multiplication rule.

$x= \frac{48960\times 15}{100}$

$x=48960\times 0.15$

$x =7,344$

Therefore: Down payment is 7,344.

Jessie works as a salesman. He earns a daily wage of 250 pesos and an additional

Darina [25.2K]

Answer:

$y = 250 + \frac{10x}{3}$

Step-by-step explanation:

Given

$Daily\ Wages = 250$

$Additional = 10$ for every 3

Required

Determine the function that represents Jessie's daily earnings:

From the question, we have that:

y = earnings

x = phones

If for 3 phones, he gets 10.

i.e.:

3 pieces = 10

then

$1\ pieces = \frac{10}{3}$ ----- By dividing both sides by 3

and

$x\ pieces = \frac{10x}{3}$ ----- By multiplying both sides by x

The above expression represents the additional earnings for x phones

So, daily earnings y is calculated as :

$y = Daily\ Wages + Additional\ Earnings$

$y = 250 + \frac{10x}{3}$
