Answer:

Soup B has more sodium per cup.

Step-by-step explanation:

If we're doing sodium per cup, then we have to divide 5 by 12, and 8 by 13.

5÷12=~0.4 grams

8÷13=~0.6 grams

0.6>0.4

So B has more sodium per cup.

Answer:

Step-by-step explanation:

answer B, because \(\sqrt{5(20+9)} \\\sqrt{5*29} \\\sqrt{145} \\\sqrt{145} = 12,0415\)

I’m pretty sure the answer should be 1,710 if not i’m sorry

Answer:

1710 fish

Step-by-step explanation:

Let the number of fish in the lake last year be 'x'

The equation becomes-
x + 15x/100=6210     (This is because 15% of x is added in x to become    
6210... hope you understand)

x + 15x/100 = 6210
115x/100 = 6210
23x/20 = 6210
x = 6210 * 20/23
x = 270 * 20
x = 5400

Therefore- The number of fish last year = 5400


Now, let the number of fish in the lake 2 years ago be 'y'

The equation becomes-
y + 20y/100 = 5400     (Same logic as last time)

y + 20y/100 = 5400
120y/100 = 5400
24y/20 = 5400
6y/5 = 5400
y = 5400 * 5/6
y = 900 * 5
y = 4500

Therefore- Fish in the lake two years ago = 4500 fish

Difference between current and two years ago = 6210-4500
                                                                               = 1710 fish

The 13th amendment because This amendment abolished slavery and involuntary servitude. For what’s happening now I think we need this amendment added to the constitution right now because a lot of people are dying for their race. Not only that but they also get accused of things that aren’t even they don’t know what happened. And it’s really sad because some people get plastic surgery because of their skin. For example Michael Jackson.

I will amendment the 13th one .

Why?

Answer:

To find the correct selling price, we need to first find the cost of the item plus the markup. We can do this by multiplying the cost of the item by the markup percentage: $6 * 67% = $4.02. However, since the question asks us to round to the nearest dollar, we can round this number down to $4.

Therefore, the correct selling price is $4.

The manager's likely error was that they set the selling price at the cost (option C).

Step-by-step explanation:

The correct selling price is $10 and the manager set the selling price at the markup so option (A) is correct.

The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.

The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.

As per the given,

Cost of item = $6

Markup = 67%

67% of $6 ⇒ 0.67 x 6 = $4.02

Add the markup in the cost = $6 + $4.02 = $10.02

Round to nearest dollars = $10.2 ≈ $10.

The manager put $4 which is a markup instant of the selling price of $10.

Hence "The correct selling price is $10 and the manager set the selling price at the markup".

Answer:

I think 8n >_ 60

Im not sure but thats what i put

Step-by-step explanation:

The inequality where n represents the minimum number of packs the teacher needs to buy is: 8n ≥ 60.

Inequality is an expression or statement of an order relationship, which involves the use of inequality signs, variables, numbers and/or algebraic expressions.

Thus:

n = number of brushes in a pack

The teacher must buy 60 brushes and above.

Thus:

8n ≥ 60 will represent the minimum number of brushes for the class.

Therefore, the inequality where n represents the minimum number of packs the teacher needs to buy is: 8n ≥ 60.

Answer:

The perimeter of the rectangle is 84 cm.

Step-by-step explanation:

From X=-17 to X=8 is 25 cm.

From Y=12 to Y=-5 is 17 cm.

Therefore, the equation is 2(25) + 2(17) = 84

The perimeter of the rectangle is 84 cm.

We need to find the length and width of the rectangle first, and then use the formula for the perimeter, which is P = 2(l + w).

The length of the rectangle is the distance between the points (-17, 12) and (8, 12), which is 8 - (-17) = 25 units.

The width of the rectangle is the distance between the points (-17, 12) and (-17, -5), which is 12 - (-5) = 17 units.

Using the formula for the perimeter of a rectangle, we have:

P = 2(l + w) = 2(25 + 17) = 84 cm

Therefore, the perimeter of the rectangle is 84 cm.

Answer:

1900

Step-by-step explanation:

hello bro how r u i think answer is 1835 but there is no option

The required mass of the proton is 1900 times the mass of the electron. Option B is correct.

Proportionality is defined as between two or more sets of values, and how these values are related to each other in the sense are they directly proportional or inversely proportional to each other.

here,
The mass of an electron is approximately e = 9.1 x 10⁻³¹ kilograms.
The mass of a proton is approximately p = 1.7 x 10⁻²⁷ kilograms.
Now

p/e =  1.7 x 10⁻²⁷/9.1 x 10⁻³¹
p/e ≈ 1900
p = 1900e

Thus, the required mass of the proton is 1900 times the mass of the electron.
