PLEASE HELP 50 POINTS

Answer:

Step-by-step explanation:

To determine how much a decimal was multiplied, you need to find how many places the decimal moved.

In this case we can see the decimal moved once. How many times the decimal moved can be represented by the zeros in the number. So 10 = 1

100 = 2     1,000 = 3 and it keeps going.

So since the decimal moved 1 time, the answer to question one is 10

Now question 2.

Both 8.4 ÷ 2.1 and 84 ÷ 21 will give the exact same answer. It is just easier to solve. So solve which one is easier for you. I did 84 ÷ 21.

84 ÷ 21 = 4

We can verify our answer by multiplying the the divisor by the quotient

21 * 4 = 84

So 4 is the answer to question 2

Answer:

fg(x) = 2x² - 1

gf(x) = 4x²-12x +10

Step-by-step explanation:

Given the functions f(x) = 2x-3 and g(x) = x^2 + 1

a) f(g(x)) = f(x²+1)

f(x²+1) = 2(x²+1) -3

f(x²+1)= 2x²+2 -3

f(x²+1) = 2x² - 1

fg(x) = 2x² - 1

Hence function fg(x) is 2x² - 1

b) gf(x) = g(2x-3)

g(2x-3) = (2x-3)² + 1

g(2x-3) = (2x-3)(2x-3) + 1

g(2x-3) = 4x²-6x-6x+9 + 1

g(2x-3) = 4x²-12x +10

gf(x) = 4x²-12x +10

Answer:

the angel is called acute angel

Answer:

61 degrees

Step-by-step explanation:

sin = opposite/hypotenuse  ->  sin x = 28/32  ->  sin x = 0.875  ->  x = arcsin 0.875 = 61.04

so the angle would be 61

Answer:

32

Step-by-step explanation:

2(2.5z − 58 + 43) = 176− 46

5z - 116 + 86 = 130

5z -30 = 130

5z = 160

z = 160/5

z = 32

Answer:

3.25 years

Step-by-step explanation:

The computation of the number of years is shown below:

Given that

PV = $225,000

RATE = 8%

PMT = $0

FV = $175,204.80

The formula is shown below:

= NPER(RATE;PMT;PV;FV;TYPE)

After applying the above formula, the number of years would be 3.25 years

The same would be considered

Given:

Kianas soccer teams ratio of wins to losses is 5:3.

Her team has played 24 games.

To find:

The number of games they won.

Solution:

Let the number of games they won be 5x and the number of games they lost be 3x.

Total number of games is 24.

[tex]5x+3x=24[/tex]

[tex]8x=24[/tex]

[tex]x=\dfrac{24}{8}[/tex]

[tex]x=3[/tex]

Now, the number of games they won is:

Number of games they won = [tex]5x[/tex]

                                               = [tex]5(3)[/tex]

                                               = [tex]15[/tex]

Therefore, they won 15 games.

Answer:

86 degrees

Step-by-step explanation:

Interior degrees of a triangle always add up to 180 degrees

What you would do is add the first two (52+31 = 84)

Subtract this number from 180 to get your remaining degrees

What is substitution method?

To find the value of any one of the variables from one equation in terms of the other variable is called the substitution method.

Given that;

The expression is;

3(-4W - 5) = -7(5 + w)

Now, Solve the expression as;

3(-4W - 5) = -7(5 + w)

3 × -4w - 3 × 5 = -7 × 5 + (-7) × w

-12w - 15 = -35 - 7w

Add 12w both side;

-12w - 15 + 12w = -35 - 7w + 12w

- 15 = 5w - 35

Add 35 we get;

- 15 + 35 = 5w - 35 + 35

20 = 5w

5w = 20

Divide 5 both side;

w = 4

Thus, The value of w will be 4.

Answer:

The Number of touchdowns the team scores

Step-by-step explanation:

Answer:

may be A?? i dont really know bt i think A

Answer: B

Step-by-step explanation:

First, let's take the point of the origin so (0,0).

Let's substitute it back into the equations:

0 is x, 0 is y

A: 0> -1 true

B: 0 ≥ -1 also true

C: 0 < -1 not true

D: 0 ≤ -1 not true

So now, for C and D the region containing the (0,0) is the unwanted region (shaded) because the inequality is not true.

However, the graph has the side with point (0,0) unshaded.

So we know that the answer is A or B.

In linear programming signs <> are expressed as dotted lines and ≤≥ as unbroken lines.

The graph has an unbroken line so answer B is correct as it has the sign ≥ (representing an unbroken line) and satisfies the inequality.

Step-by-step explanation:

Purchase Cost= £12 for 10kg

Sales

1 bag= 200g

200g=1 bag

1 g= 1/200 bag

10000g or 10kg= 1/200 * 10000 = 50 Bags

1 Bag = 0.60

50 Bags= 0.60*50= £30

Profit= £30- £12= 18

% Profit= 18/12 *100

The sales tax for the shirt is 0.05(0.4x).

Calculating the sales tax applied to a purchase is a matter of simply multiplying the tax rate by the purchase price using the equation sales tax = purchase price × sales tax rate. Adding the sales tax to the original purchase price gives the total price paid with tax.

Given that, a shirt priced at x dollars is discounted before tax is added.

In the final price, (x-0.6x) represents the discount of 60% on the shirt.

After that sales tax was applied which was 1.05 ≈ 105%. So, the sales tax is 5%

Then the sales tax is

5% × (x - 0.6x)

5% × (0.4x)

0.05(0.4x)

Therefore, the sales tax for the shirt is 0.05(0.4x).
