Answer 1

Answer:

3y

Step-by-step explanation:

Sqrt of 9 = ±3

-±3[tex]\sqrt{y^{2} }[/tex]

the square and sqrt cancel leaving you with -±3y

Since y < 0, the sqrt of 9 should be -3 to cancel out the - sign in front.

Answers

Answer:

18

Step-by-step explanation:

If the average of 6 numbers is 10, then the sum of those 6 numbers is:

6 x 10 = 60

To calculate the sum of the remaining 10 numbers, subtract 60 from the total sum of all the numbers:

240 - 60 = 180

Therefore, the average of the 10 remaining numbers:

Paulo has R$45.00 and Carlos has 5/9 of that amount. How many Carlos has? How many do the two have together?​

Answers

Paulo has R$45.00 and Carlos has 5/9 of that amount. How many Carlos has? How many do the two have together?

We are given –

Paulo has R$45.00 and Carlos has 5/9 of that amount.

We are asked to find, how much Carlos owns and how much they have together.

Explanation :-

At first, we just need to multiply 45 by 5, and then we will divide the value by 9, so we find that:

[tex]\qquad[/tex][tex] \bf \longrightarrow 45 \times 5 = 225[/tex]

[tex]\qquad[/tex][tex] \bf \longrightarrow \dfrac{225}{9} = 25[/tex]

Therefore, we find that Carlos has 25 R$.

Now to find out how much they have together. We have to add Paul's amount to Carlos' amount for that.

[tex]\qquad[/tex][tex] \bf \longrightarrow 25 + 45 = 70[/tex]

Henceforth, they both have 70 R$. together.

sarah hopes to be 5 feet in her next birthday. right know she is 148 cenmeter tall.how many more centimerter does sarah need to grow before her next borthday

Answers

Answer:4

Step-by-step explanation:

Well its actually 4.4 but if you round down its 4 centimeters and 5 feet equals 152.4 so that minus 148 is 4.4

Answer:

Step-by-step explanation:

1 foot is 12 inches

1 inch = 2.54 cm

12 inches = 2.54 cm * 12 = 30.48 cm

5 feet make 30.48 cm * 5 = 152.4 cm

She is currently 148 cm

She needs to grow 152.4 - 148 = 4.4 cm

The members of the city cultural center have decided to put on a play once a night for a
week. Their auditorium holds 600 people. By selling tickets, the members would like to raise $3,300
every night to cover all expenses. Let d represent the number of adult tickets sold at $7.50. Lets
represent the number of student tickets sold at $4.50 each. If all 600 seats are filled for a
performance, how many of each type of ticket must have been sold for the members to raise exactly
$3,300? At one performance there were two times as many student tickets sold as adult tickets. If
there were 300 tickets sold at that performance, how much below the goal of $3,300 did ticket sales
fall?

Answers

To answer the first question, we have these two equations:

x + y = 500 and 7.5x + 4.5y = 2550

We can use substitution to solve for x and then plug it back into any equation and find y.

y = 500 - x

7.5x + 4.5 (500 - x) = 2550

7.5x + 2250 - 4.5x = 2550

3x = 300

x = 100 adults

100 + y = 500 → y = 400 students

To answer your second question, we have two new equations:

2x = y (This may be confusing, but since there were more student tickets sold, it is the larger number.)
x + y = 300

We can rewrite the first equation and add them together:

2x - y = 0
x + y = 300

3x = 300

x = 100 adults

100 + y = 300 y = 200 students

The money earned from these 300 people is 100 * 7.5 + 200 * 4.5 = 750 + 900 = $1650.

$2550 - $1650 = $900

The 300 tickets sold had a $900 fall in ticket sales.

Kiara had the following car expenses last year: $3060 in car payments; $94 for license
and registration: $128 in tax; $1080 for insurance; $290 for parking; $398 for wear and
tear, $1520 for maintenance; and $930 for gas. If she drove 12,500 miles last year, what
was her average cost per mile?

Answers

Average cost per mile is $0.6

How to calculate the average cost per mile?

To calculate the average cost per mile that Kiara had to pay, we perform the following operations:

We add up all the payments Kiara made related to her car.

$3,060 + $94 + $128 + $1,080 + $290 + $398 + $1,520 + $930 = $7,500

Later we divide the total value, in the number of miles traveled by Kiara

$7,500 ÷ 12,500 miles = 0.6

A restaurant receives a shipment of 5,000 ketchup packets. In one week, they use 1,779 packets. The next week, they use 2,415 packets. How many ketchup packets does the restaurant have left?

Answers

Answer:

806 ketchup packets

Step-by-step explanation:

5000-1779=3221

3221-2415=806

The restaurant has 806 ketchip packets left

Answer:

5,806

Step-by-step explanation:

Because they got there 5,000 packets they subtracted 1,779 packets

5,000-1,779=3,221

Next remember they get 5,000 packets each week so then you add 5,000 to 3,221

3,221+5,000=8,221

next 2,415 packets were used so subtract 8,221 bu 2,415

8,221-2,415=5,806  so there's your answer

Please help it’s urgent

Answers

Answer: $112

Step-by-step explanation:

o get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 560 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 560 is 100%, so we can write it down as 560=100%.

4. We know, that x is 20% of the output value, so we can write it down as x=20%.

5. Now we have two simple equations:

1) 560=100%

2) x=20%

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

560/x=100%/20%

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 20% of 560

560/x=100/20

(560/x)*x=(100/20)*x       - we multiply both sides of the equation by x

560=5*x       - we divide both sides of the equation by (5) to get x

560/5=x

112=x

x=112

now we have:

20% of 560=112

x-2y=8
8x+6y=42

Answers

Answer:

(6,-1)

Step-by-step explanation:

Hi there!

We are given the following system:
x-2y=8

8x+6y=42

And we want to solve it by substitution

Substitution is where we solve one of the equations in the system for a variable for an expression containing the other variable, then substitute that expression into the other equation, then solve the equation for that variable, then use the value of the solved variable to find the value of the first variable.

It's easier to solve a system for a variable if the leading coefficient in front of a variable is 1, like with x in x-2y=8

So let's solve the equation for x.

add 2y to both sides

x-2y=8
 +2y +2y
________________
x=2y+8
Now substitute 2y+8 as x in 8x+6y=42

8(2y+8)+6y=42

Multiply

16y+64+6y=42

Subtract 64 from both sides

16y+6y=-22
Add 16y and 6y together

22y=-22

Divide both sides by 22

y=-1

Substitute -1 as y into x=2y+8 to solve for x

x=2(-1)+8

Multiply

x=-2+8

x=6

The answer is x=6, y=-1, or as a point, (6, -1)

Answer:

m∠Q = 121°

m∠R = 58°

m∠S = 123°

m∠T = 58°

Step-by-step explanation:

The sum of the interior angles of a quadrilateral = 360°

Create an expression for the sum of all the angles and equate it to 360, then solve for x:

      ∠Q + ∠T + ∠S + ∠R = 360

⇒ 2x + 5 + x + 2x + 7 + x = 360

⇒ 6x + 12 = 360

⇒ 6x = 360 - 12 = 348

⇒ x = 348 ÷ 6 = 58

So now we know that x = 58, we can calculate all the angles:

m∠Q = 2x + 5 = (2 x 58) + 5 = 121°

m∠R = x = 58°

m∠S = 2x + 7 = (2 x 58) + 7 = 123°

m∠T = x = 58°
