How are Ratios,rates and unit rates used to solve problems?

insens350 [35]

Answer:

hope u understand

Step-by-step explanation:

Unit rates can conveniently be multiplied by any desired number in order to answer questions about differently scaled questions. E.g. If three marbles cost 30 cents, how much will eleven marbles cost?

A unit rate is a ratio such as 30 cents : 3 marbles = 10 cents per (1) marble, after doing the division.

A box of candy weighs 340.23 grams and costs $18.99. If 1 gram is approximately 0.03527 ounces, what is the unit price per ounce

svlad2 [7]

The correct answer is: [C]: " $ 1.58 " .
_______________________________________________
Explanation:
______________________________________________
Given:
______________________________________________
$18.99 per 340.23 grams ;

and given:

1 gram ≈ 0.03527 oz (ounces) ;
______________________________________________
Find the unit price per OUNCE (oz).
______________________________________________
Given: $18.99 per 340.23 grams ;

Convert: "340.23 grams" to "ounces (oz)".

Given: "1 gram ≈ 0.03527 oz" ;

340.23 grams = (340.23 * 0.03527) oz. = 11.9999121 (about "12 oz.").

So, $19 / 12 oz. = ? dollars per UNIT OZ. ; =

(19/12) dollars per oz. = (19÷12) dollars per oz. = $ 1.58333 ; which corresponds to: Answer choice: [C]: $1.58 .

Hey, I need help with questions 1 and 2, if anyone can help, please? thanks!

The correct works are:

$Blue(s + h) = 2s^2 + 4sh + 2h^2 + 3$ .
$\frac{Blue(s + h) - Blue(s)}{h} = 4s + 2h$

<h3>Function Notation</h3>

The function is given as:

$Blue(s) = 2s^2 + 3$

The interpretation when Steven is asked to calculate Blue(s + h) is that:

Steven is asked to find the output of the function Blue, when the input is s + h

So, we have:

$Blue(s + h) = 2(s + h)^2 + 3$

Evaluate the exponent

$Blue(s + h) = 2(s^2 + 2sh + h^2) + 3$

Expand the bracket

$Blue(s + h) = 2s^2 + 4sh + 2h^2 + 3$

So, the correct work is:

$Blue(s + h) = 2s^2 + 4sh + 2h^2 + 3$

<h3>Simplifying Difference Quotient</h3>

In (a), we have:

$Blue(s + h) = 2s^2 + 4sh + 2h^2 + 3$

$Blue(s) = 2s^2 + 3$

The difference quotient is represented as:

$\frac{f(x + h) - f(x)}{h}$

So, we have:

$\frac{Blue(s + h) - Blue(s)}{h} = \frac{2s^2 + 4sh + 2h^2 + 3 - 2s^2 - 3}{h}$

Evaluate the like terms

$\frac{Blue(s + h) - Blue(s)}{h} = \frac{4sh + 2h^2}{h}$

Evaluate the quotient

$\frac{Blue(s + h) - Blue(s)}{h} = 4s + 2h$

Hence, the correct work is:

$\frac{Blue(s + h) - Blue(s)}{h} = 4s + 2h$

Answer:

$11.00

Because .70 + .10 = .80

.80 times 55 = 44

55 - 44 = 11

If you add tax however, it would be 11.66.

Because 11 times .06 = .66

.66 + 11 = 11.66

Which digits make 3,71 divisible by 3 a.3 only b.7 only c.1 only d.1,4 and 7

Rzqust [24]

The answer would be 1,4, and 7. if you place each of those into the "3,71_" and then divide them by 3, you'll see that those three number make it divisible by three. its pretty much a guess and check question. you just have to test each answer choice.
