Answer:

A - True

B - False

Step-by-step explanation:

Looking at option A,

Company B had 3.12 subscribers and earned 119. To find each subscriber's value we divide 119 by 3.12

119/3.12 = 38.14

Looking at Option B,

Company A had 2.45 subscribers and earned 108. To find each subscriber's value, we divide 108 by 2.45

108/2.45 = 44.08

Hence, for Option A, each subscriber paid about $40 is correct because it's close to 38.14

For Option B, each subscriber paid about 30 is incorrect since it's way over, 44.08.

Thus,

A - True

B - False

Jen buys sesame bagels and plain bagels. If the ratio of sesame to plain is 1:3 and Jen bought 2 dozen bagels, what percent of b

Ulleksa [173]

Answer:

The number of plain bagels are 18 and it is 75% of the total bagels .

The amount of salt in a plain bagel to that in a sesame bagel is 81.5% .

Step-by-step explanation:

Formula

$Percentage = \frac{Part\ value\times 100}{Total\ value}$

As given

Jen buys sesame bagels and plain bagels. If the ratio of sesame to plain is 1:3 and Jen bought 2 dozen bagels .

As one dozens contains 12 items .

Thus

Total number of bagels bought by Jen = 2 × 12

= 24

Let us assume that the x be the scalar multiple of sesame bagels and plain bagels .

Number of sesame bagels = 1x

Number of plain bagels = 3x

Than the equation becomes

x + 3x = 24

4x = 24

$x = \frac{24}{4}$

x = 6

Thus

Number of plain bagels = 3 × 6

= 18

Part value = 18

Total value = 24

Putting all the values in the formula

$Percentage = \frac{18\times 100}{24}$

$Percentage = \frac{1800}{24}$

Percentage = 75 %

Therefore the number of plain bagels are 18 and it is 75% of the total bagels .

As given

Suppose each plain bagel has 0.53 gram of salt, and each sesame bagel has 0.65 gram.

Part value = 0.53 grams

Total value = 0.65 grams

Putting all the values in the formula

$Percentage = \frac{0.53\times 100}{0.65}$

$Percentage = \frac{5300}{65}$

Percentage = 81.5 %

Therefore the amount of salt in a plain bagel to that in a sesame bagel is 81.5% .

How many solutions would there be for the following systems of equations <br>y=3x-5<br>6x-2y=10

Ann [662]

Answer:

So the solution would be (1,-2). Remember you can always validate that the solution is correct by plugging it into both equations. But this is the same as the first equation, y=3x-5. Since they are the SAME line they will have infinite solutions.

Help me plz i don't get it

Butoxors [25]

This is asking for x and y coordinates. for example, 1 ticket is $34, right? so on the x side, there is a 1, and on the y side theres a 34. the order pair would be (1, 34). then graph it. the equation would be y=34x. hope this helps!
