Can someone explain this

Given:

The ratios are  [tex]\dfrac{30}{75}[/tex] and [tex]\dfrac{24}{60}[/tex].

To find:

Whether the ratios form a proportion or not.

Solution:

If two ratios represent the same relationship then they form a proportion.

We have,

[tex]\dfrac{30}{75}[/tex] and [tex]\dfrac{24}{60}[/tex]

Write the given ratios in the simplified forms.

[tex]\dfrac{30}{75}=\dfrac{15\times 2}{15\times 5}[/tex]

[tex]\dfrac{30}{75}=\dfrac{2}{5}[/tex]

And,

[tex]\dfrac{24}{60}=\dfrac{12\times 2}{12\times 5}[/tex]

[tex]\dfrac{24}{60}=\dfrac{2}{5}[/tex]

Since [tex]\dfrac{30}{75}=\dfrac{24}{60}=\dfrac{2}{5}[/tex], therefore the ratios form a proportion.

Answer:

25%

Step-by-step explanation:

We know that there are ten purple popsicles. Together without the purple popsicles, there are 40 popsicles in total. Therefore there is a 10/40 chance to get purple. We need to turn this into a percentage so we do (10 / 40) x 100. This would equal to 25%, therefore, there is a 25% probability to get a purple popsicle.

Answer:

Tamara incorrectly factored the whole expression.

Step-by-step explanation:

Note that

•21x=3·7·x;

•56xy=2·2·2·7·x·y.

Mark in bold all common factors, then GCF(21x,56xy)=7·x=7x.

Thus,

21x+56xy=7x(3+8y).

Hence, Tamara correctly found the GCF of numbers 21 and 56, but incorrectly factored the whole expression.

Step-by-step explanation:

9 x 37 = 333

Answer:

$333

Step-by-step explanation:

As, the total hours Eleanor works = 37

And per hour he gets = $9

= $333

Answer:

40

Step-by-step explanation:

xy + x         x= -10    y= -5

Plug in the given values and remember that multiplying two negative numbers makes the product positive.

(-10)(-5) + -10

50 - 10

40

Answer:

2. 40

all you have to do is fill in the letters with their values.

Step-by-step explanation:

xy + x = ?

-10 (-5) + (-10) = ?

50 + (-10)= 40

40 = 40

Answer:

you would need 18 quarts of sparkling water to mix with 9 quarts of grape juice

Step-by-step explanation:

1 1/2 is double of 3/4 so you just need to double 9 quarts of grape juice

Answer:

18 quarts of sparkling water

Step-by-step explanation:

9÷0.75=12 to figure how many times the recipe is multiplied.

12x1.5=18 to figure out how much sparkling water

3/4 = 0.75

1 1/2 = 1.5

Answer:

y = 6x + 104

Step-by-step explanation:

Given the equation in the form:

y = mx + b

m = slope ; b = intercept

Given the data:

5 days - $134 10 days - $164 15 days - $194 20 days - $224

To obtain the slope, Pick the points :

(5, 134) and (20, 224)

Slope = y2 - y1 / x2 - x1

Slope, m = (224 - 134) / (20 - 5) = 90 / 15 = 6

Plugging into the equation :

We have ;

y = 6x + b

Picking any point from the data and plugging in to solve for b:

(10, 164)

164 = 6(10) + b

164 = 60 + b

b = 164 - 60

b = 104

Equation finally becomes ;

y = 6x + 104

Answer:

d

Step-by-step explanation:

in order for it to be a triangle the angles have to add up to equal 180

5+75+100=180 so its not a

10+80+90=180 so its not b

20+60+100=180 so its not c

45+45+45=135 so its d because the angles dont add up to 180

50+50+80=180 so its not e

Answer:

D

Step-by-step explanation:

To be a triangle, you have to have 180 degrees. if you add up all of the sides, it should give you 180. If it doesn't, it isn't a triangle. I hope that helped! :)

Plz consider giving me brainliest answer as I am trying to reach a new level, thanks!

I don't know how to give brainliest tho.

Answer:

112 degrees

Step-by-step explanation:

Since the two sides opposite of angle 1 and 2 are congruent, as shown by the double tic marks, the angles are conguent. The total sum of all angles must be 360 degrees, so we know 90 degrees was given, as well as 46 degrees. That's 136 degrees together, subtract that from 360 and you get 224. Angles 1 and 2 are congruent so both add to 224, therefore each angle is 112 degrees.
