Answer: The ratio is 18:3

Step-by-step explanation:

Answer:  6 to 1

Step-by-step explanation:

A ratio refers to a fraction. In this case the question asks how many players to coaches there are.

The word "to" means that is where the fraction bar goes.

Players/Coaches

There are 18 players and 3 coaches.

18/3

18 can be divided by 3, 6 times so the fraction can be simplified to

6/1 meaning there are 6 players for every coach.

Answer:14

Step-by-step explanation:

abcd = wxyz

ad/dc=wz/yz

12/3=4

56/yz=4

yz=14

Answer:The lengths of AB and EF are 10 and 2 respectively

If the triangle ABC and DEF are similar, based on the similarity theorem of a triangle;

AB/DE = BC/EF

5x/4 = 5/x

5x² = 20

x² = 20/5

x² = 4

x = 2

Since the value of x is 2, length of AB is 5x = 5(2) = 10

Since EF = x, hence EF = 2

The lengths of AB and EF are 10 and 2 respectively

Answer:

-2/3

Step-by-step explanation:

You are looking the change in y over  the change in x.

for y, if you go from -5 to -7, how much did it change?  -2

-7 -(-5) = -7 + 5 = -2

Now look the the x's.  If you from 6 to 9 how much did you change?

3

9-6 = 3

-2/3

Answer:

-2/3

Step-by-step explanation:

A slope is [tex]\frac{Change in Y}{Change in X}[/tex] and we can see that when the x value increases by 3, the y value decreases by 2. So if we plug that in, we get -2 for the Change in Y and +3 for the Change in X. Which results in the slope being [tex]-\frac{2}{3}[/tex]

Answer:

The point would be (2.5,8.75)

Because we know the customer paid $8.75, we use the y-axis to find this point. Then we'll find where the line meets 8.75 on the y-axis. This is at 2.5. We know that points are in the order of (x,y) therefore the point is (2.5,8.75)

Step-by-step explanation:

The options 1,2 and 5 are the correct answer.

The given equation is 1.23/[tex]10^1[/tex]=0.123.

The division is one of the basic arithmetic operations in math in which a larger number is broken down into smaller groups having the same number of items.

Now,

1) 1.23/[tex]10^1[/tex]=0.123

Here LHS=RHS

2) 123/100=1.23

Here LHS=RHS

3) 12.3/[tex]10^0[/tex]=1.23

⇒ 12.3/1=12.3

So, LHS≠RHS

4) 0.123/10=1.23

⇒ 0.123/10 = 0.0123

So, LHS≠RHS

5) 1230/10³=1.23

⇒ 1230/1000

= 1.23

Here LHS=RHS

Therefore, the options 1,2 and 5 are the correct answer.

Answer: b

Step-by-step explanation:

Barry is given 0.4 and 0.9 cents

He already has 6.30 in his bank

0.4+0.9 = 1.3

add the money he was given to the bank

1.3 + 6.3 = $7.60

Barry has $7.60 in total.

Henry buys two candy bars, one is worth 3.20 and the other is 1.60

add them up to get the total

3.20 + 1.60 = 4.80

Henry has $8.50

subtract the cost of the chocolate from the money he has

8.50 - 4.80 = $3.70

Henry has $3.70 left over from the $8.50

Beth buys a bouncy ball worth 1.20 and pen that is 5 times that amount.

this put into an equation is

1.20 + (5*1.20) =

1.20 + 6 =

the answer to this equation is

$7.20

The bouncy ball and pen cost $7.20 in total.

Joe found 1 dollar ($1), 4 quarters ($1), and 3 dimes ($0.30) on Monday

In total that is,

1 + 1 + 0.30 = $2.30

He found $2.30 on monday

On tuesday, he finds 3 times that amount

3 * 2.30 = $6.90

He found $6.90 on tuesday

add them up and you get

2.30 + 6.90 =

$9.20

Joe found $9.20 on Monday and Tuesday combined.

Answer:

1. $7.60

2. $3.70

3. $7.20

4. $5.20

Step-by-step explanation:

1. 0.40+0.90+6.30= 7.60

2. 8.50-(3.20+1.60)=3.70

3. 1.20+(1.20*5)= 7.20

4. (1+1+0.30)+(1+1+0.30*3)= 5.20

Answer:

The Point in the coordinate plane is A(-5,-4)

Perpendicular or shortest Distance from line y=3 that is (-5,3) to point (-5,-4) is

When it is reflected through the line, y=3, the coordinate of point A (-5,-4) changes to (-5,3+7)= B(-5,10).

Now, the Point B is translated by the rule , (x,y)—->(x+6,y),

So,the point B is translated to, (-5+6,10)=(1,10)

(1,10) is the glide reflection of point A(-5,-4).

Answer:

Jiri's age = 27

Step-by-step explanation:

Let's use x for Jiri's age.

Jiri's age = x

And because Pamela is 8 years older:

Pamela's age = x + 8

Since their ages added up equal 62, the equation will be:

x + x + 8 = 62

2x + 8 = 62

2x + 8 - 8 = 62 - 8

2x = 54

2x/2 = 54/2

x = 27

And because Jiri's age is x, Jiri's age will therefore be 27.

Hope this helped!

Answer:

Jiri is 27 years old.

Step-by-step explanation:

Step 1: Declare variables

Since Pamela is 8 years older than Jiri. Then, Pamela’s age is [tex]\displaystyle{8+x}[/tex] years old.

Step 2: Form an equation

The sum of their ages together equals to 62. Therefore, we can express in mathematics/equation of [tex]\displaystyle{x+8+x=62}[/tex] (sum of Jiri’s age and Pamela’s).

Step 3: Solve for x-term - add like terms (x-term)

[tex]\displaystyle{2x+8=62}[/tex]

Step 4: Subtract both sides by 8

[tex]\displaystyle{2x+8-8=62-8}\\\\\displaystyle{2x=54}[/tex]

Step 5: Divide both sides by 2

[tex]\displaystyle{\dfrac{2x}{2}=\dfrac{54}{2}}\\\\\displaystyle{x=27}[/tex]

Since Jiri’s age is defined as [tex]x[/tex] years old. Therefore, Jiri’s age is 27 years old.

Answer:

the first one

Step-by-step explanation:

Answer:

5. [tex]7^{5}[/tex]

6. [tex]27+15=42[/tex]

7. [tex]\frac{u}{10}=100[/tex] then multiply both sides by 10: [tex]u=100*10 \\u=1000[/tex]

8. [tex]28+r=128[/tex] subtract 28 from both sides: [tex]r=100[/tex]

9. So we are going to use the formula [tex]A=l*w[/tex]: [tex]A=4*2.5\\A=10[/tex]

10. So we are going to use the formula [tex]A=b*h[/tex]: [tex]A=9*4\\A=36[/tex]
