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:

0.84

5/5= 1

1 / 3/4 = 0.8333...

0.8333... = 0.84

Answer:

3/4

Step-by-step explanation:

because 5 divided by 5 is 1 and 1/1 divided by 3/4 is 3/4

(5,3) is the answer for the current question

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

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

sorry if it's wrong

Answer:

x = 12    y = 24     z = 12[tex]\sqrt{3}[/tex]

Step-by-step explanation:

you are correct.  x = 12

The dotted line has a length of 12 also

The dotted line is the shorter leg of the 30-60-90 triangle.

So, z = 12[tex]\sqrt{3}[/tex] and y = 24

Answer:

the probability in the case when the white pen would be removed from the drawer is 1 ÷ 30

Step-by-step explanation:

The computation of the probability in the case when the white pen would be removed from the drawer is given below

= Favorable outcome ÷ total outcome

= 1 ÷ 30

Hence, the probability in the case when the white pen would be removed from the drawer is 1 ÷ 30

We simply applied the above formula

Answer:

10

Step-by-step explanation:

8 is closest to 10 therefore 8 rounds up to 10

Let two consecutive numbers are : x,x+1

Sum of these numbers is -11, then

x+x+1=−11

⇒2x=−11−1=−12

⇒x=−6

and other consecutive number is x+1=−6+1=−5

The answer is -6 and −5

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:

just simply add all of the terms together.

Answer:

not sure if that is right

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).

#SPJ2

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:

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

Step-by-step explanation:

Answer: 4 parfaits.

Step-by-step explanation: 1/2 divided by 1/8. when you divide you flip the second fraction and multiply it so now it's 1/2 x 8/1 which is 8/2 and then is turned into 4 so 4 parfaits

Hope this helps im really good at fractions if you need anything else lol :')

Width - x

Length - (x+12)

Area - x(x+12)

x(x+12)=220

x²+12x-220=0     -220 =22*(-10), 12=22-10

(x+22)(x-10)=0

x=-22, x=10

For width, we can use the only positive number,

so, the width is 10 feet.

Length is 10+12=22 feet.
