Answer:

Answer is A.[tex]3.6*10^{5}[/tex]

Step-by-step explanation:

Mass of Sodium Chloride in one 50kg person = [tex]2*10^{2}[/tex] grams

Mass of Sodium Chloride in [tex]1.8*10^{3}[/tex] 50kg people = [tex]2*10^{2}[/tex] * [tex]1.8*10^{3}[/tex]

=[tex](1.8*10^{3})*(2*10^{2})[/tex]

=[tex]3.6*10^{5}[/tex]

So the Answer is A.

In this pattern all are divisible by 5

20[tex] =4×5[/tex] i.e. divisible by 5

25[tex] = 5×5 [/tex] is divisible by 5

30[tex] =2×3×5[/tex] is divisible by 5

35[tex] =7×5 [/tex] is divisible by 5

Hence the pattern contain factor 5

The statement that correctly describes the pattern 20, 25, 30, 35, ... is that it contains only factors of 5.

The given sequence of numbers is 20, 25, 30, 35,... and the correct statement describing this pattern is that it contains only factors of 5. This is because each number in the sequence is a multiple of 5 and can be divided by 5 without leaving a remainder. The sequence is not exclusively even or odd numbers, as it contains both (20 and 30 are even, while 25 and 35 are odd). Also, the pattern is not decreasing; it is instead increasing by increments of 5.

Answer: 220

Step-by-step explanation:

Children (x): $2

Teens (y): $3, [tex]\frac{3}{4}x[/tex]

Adults: (z): $5

Quantity: x + y + z = 570  ⇒  x + [tex]\frac{3}{4}x[/tex] + z = 570  ⇒ 1.75x + z = 570  

Cost: 2x + 3y + 5z = 1950  ⇒  2x + 3[tex](\frac{3}{4}x)[/tex] + 5z = 1950  ⇒  2x + 2.25x + 5z = 1950  ⇒  4.25x + 5z = 1950

Qty:    1.75x +  z =  570  →  5(1.75x +  z =  570)  →    8.75x + 5z = 2850

Cost: 4.25x + 5z = 1950 → -1(4.25x + 5z = 1950 → -4.25x - 5z = -1950

                                                                                  4.50x        =   900

                                                                                          x       =    200

Teens (y): [tex]\frac{3}{4}x[/tex]

           y = [tex]\frac{3}{4}(200)[/tex]

             = [tex]\frac{600}{4}[/tex]

             = 150

Quantity: x + y + z = 570  

              200 + 150 + z = 570

                     350     + z = 570

                                    z = 220

z-score fore -1.2 = 0.1151

z-score for 0.85 = 0.8023

Subtract :

0.8023 - 0.1151 =0.6872

The answer is C.

The greatest amount of trips that Edwin can take up the mountain and still pay less than Rhea would be 63.

Inequality is defined as the relation which makes a non-equal comparison between two given functions.

Two siblings Edwin and Rhea are both going skiing but choose different payment plans.

Edwin's plan charges $45 for rentals and $5.25 per lift up the mountain.

Rhea's plan was a bundle where her entire day cost $108.

An inequality that models the number of trips, n, up the mountain for which Edwin will pay more than Rhea.

45 + 5.25n > 108

Subtract 45 on both sides

-45 + 45 + 5.25n > 108 -45

5.25n > 63

Divide both sides by 5.25

n > 12

Also,

5.25 x 12

= 63

The greatest amount of trips that Edwin can take up the mountain and still pay less than Rhea would be 63.

Step-by-step explanation:

C) y = 3b − 5

It is “5 fewer than 3 times”

Answer:

y = 3b-5

Step-by-step explanation:

The number of yellow fish is 5 fewer than 3 times the number of blue fish.  Using b to represent the number of blue fish, 3 times this is 3b; 5 fewer than this is 3b-5.  This gives us the equation

y = 3b-5

question a - you run 30 yards (divide by 5 then muliply by 6) so Jill runs 36 yards.  

question b - Jill runs 54 yards (divide by 6 then multiply by 5) so you run 45 yards.

If I were to graph this as a venn diagram I would be able to see a relationship between these sets of numbers because 2 and -4 are an ordered pair. Most relations in math are between two sets and is a collection of ordered pairs.

Choice A

Answer: Choice A. Hope this helped :)

Step-by-step explanation:

Here is your equation:

[tex]6 \frac{7}{8} + 7 \frac{5}{12}[/tex]

As you can see, the denominators, which is the bottom number in the fraction, are different. You need to have the same denominator, so that you can add it. To change the denominators, you need to find the LCM of both denominators, which is 8 and 12. To find the LCM, first list the multiples of both numbers and see what is common.

[tex]8 - 8, 16, 24, 32, 40, 48, 56 \\12-12, 24, 36, 48[/tex]

The only common number is 48. That means you need to change both fractions so that they have a denominator of 48.

[tex]6 \frac{7 \times 6}{8 \times 6} \rightarrow 6 \frac{49}{48}[/tex]

[tex]7 \frac{5 \times 4}{12 \times 4} \rightarrow 7 \frac{20}{48}[/tex]

Here is your new equation:

[tex]6 \frac{49}{56} + 7 \frac{20}{48}[/tex]

Add:

[tex]6 \frac{49}{48} + 7 \frac{20}{48} = 13 \frac{69}{48}[/tex]

Simplify:

[tex]13 \frac{69}{48} \rightarrow 14 \frac{21}{48} \rightarrow 14 \frac{7}{16}[/tex]

Your answer is 14 [tex]\frac{7}{16}[/tex]

If you have any questions, feel free to ask in the comments! :)

Multiply both sides by 8

5/8g × 8 = 40× 8

5g = 320

Divide both sides by 5

5g/5 = 320/5

I'm not sure what the question is but if your trying to find out how many t-shirts he bought it would be 7.

Here's why...

90$-34$= 56

56/8= 7

He could buy 7 shirts with the left over money he had.

Hope this answered your question. :)

Final answer:

Steven spent $90 in total, bought jeans for $34, and used the remaining $56 to buy T-shirts that cost $8 each, allowing him to purchase 7 T-shirts.

Explanation:

The student’s question is a simple mathematics word problem involving subtraction and division. Steven spent a total of $90 on clothes. After purchasing jeans for $34, he used the remainder of his money to buy T-shirts costing $8 each. To solve this, we first subtract the cost of the jeans from the total amount to find out how much money was left for T-shirts:

$90 (total amount) - $34 (cost of jeans) = $56

Next, we calculate the number of T-shirts Steven could buy with the remaining $56 by dividing this amount by the cost of one T-shirt:

$56 ÷ $8 (cost per T-shirt) = 7 T-shirts

Therefore, Steven was able to purchase 7 T-shirts with the rest of his money.

y=2x−26 because the form for standard slope is: y=mx+b

you have to find the slope by doing y-y/x-x and then you plug the slope you get into m and then you pick a point; either (82,-96) or (87,-86) and you plug it in for the x and y in y=mx+b and you work out the equation from there.

Final answer:

Juan will be purchasing 32 square feet of plywood in all for constructing the doghouse, calculated by summing the areas of four 2 ft x 3 ft rectangular pieces and two 2 ft x 2 ft square pieces.

Explanation:

Juan is constructing a doghouse and needs to calculate the total square footage of plywood required for both rectangular and square pieces. To determine this, we calculate the area of each piece of plywood and then sum them up. The area of a rectangle is given by multiplying its length by its width, and for a square, each side is of equal length, so we multiply the length of one side by itself to find the area.

The four rectangular pieces are 2 ft by 3 ft, so each one has an area of:

2 ft × 3 ft = 6 square feet

Since there are four such pieces, this amounts to:

4 pieces × 6 square feet per piece = 24 square feet

The two square pieces are 2 ft by 2 ft, so each one has an area of:

2 ft × 2 ft = 4 square feet

Thus, the total for the two square pieces is:

2 pieces × 4 square feet per piece = 8 square feet

Adding both totals together, Juan will be purchasing:

24 square feet + 8 square feet = 32 square feet of plywood in all.

(10)2 x (6)3 = 38

It will cost $38 for 2 adult's and 3 children's tickets.

This is a trick question as I'm sure you know, so the answer is 1.

Anything to the power of 0 = 1 and here is why:

[tex](11,882)^0[/tex] Is the equation, but in reality this is what you have: [tex]1(11,982)^0[/tex]

11,982 cancels out and so you are left with just 1

The range of the function is -4 < x ≤ 4.

The range of a function is all of the values of y that the graph could contain. In this case, x varies between -4 and 4. We should have a < symbol at -4 because it doesn't include -4 due to the open circle. We should have a ≤ with 4 since it has a closed dot.

f(3) = 1

substitute x = 3 into f(x)

f(3) = (2 × 3) - 5 = 6 - 5 = 1

To find the value of f(3) for the function f(x) = 2x - 5, substitute x = 3 into the function. The value of f(3) is 1.

To find the value of f(3) for the function f(x) = 2x - 5, we substitute x = 3 into the function.

So, f(3) = 2(3) - 5.

Simplifying further, we get f(3) = 6 - 5 = 1.
