y = kx

9.6 = k * 6

k = 9.6/6

k = 1.6

Answer:

12 and a half minutes ago

Step-by-step explanation:

In five minutes, the pool drained 180-120=60 gallons of water. This means that the pool loses 60/5=12 gallons of water per minute.

You can make the equation 270-12x=120, where x is the amount of minutes passed.

Subtract 270 on both sides to get -12x=-150

Divide both sides by -12

x=150/12 which is 12.5

Therefore, x=12.5 or 12 and a half minutes ago

Answer:

a reflection of a point over the y -axis is shown. the rule for a reflection over the y -axis is (x,y)→(−x,y) .

Answer:

c)

Step-by-step explanation:

y = mx +c

c is y-intercept. At y-intercept , x = 0.

So, from the table, c = -5

y = mx  - c

Choose any point from the table and Plugin the values in the above equation.

(4 , 1.4)

1.4 = m*4 - 5

1.4+5 = 4m

6.4=4m

6.4/4 = m

1.6 = m

y = 1.6x - 5

Answer:

James is 19 years old.Mindy is 21 years old. Laura is 63 years old.

Step-by-step explanation:

Let James age be x.

Then Mindy will be x + 2

Then Laura will be 3(x + 2)

If they sum up, the total age is 103 years.

3(x + 2) + x + 2 + x = 103

3x + 6 + x + 2 + x = 103

5x + 8 = 103

5x = 95

x = 19 years

James is 19 years old.

Then Mindy is (x + 2)

                     → 19 + 2

                     → 21 years old

Then Laura shall be 3(x + 2)

                                  → 3(19 + 2)

                                  → 3(21)

                                  → 63 years old

Answer:

50000

Step-by-step explanation:

Start by identifying the part (50000) and the percentage (30%). If you know these two values, you can find the whole. By replacing the given values in the formula, you get: Now cross-multiply: 30 × whole = 50000 × 100 Then, divide both sides by 30 and get the whole:

C=25degree

Answer:

is 3, because ‘six’ has three letters

Answer:

I would say C

Step-by-step explanation:

There is no concrete numbers to determine that the sides are the same. However, they are both right triangles with 90 degree angles. They also have vertical angles, which are always congruent. Therefore your answer would be C.

Answer:

Tray has 24 bottles

1 bottle =12 oz

12bottles= 24×12=288

288÷30=9.6

30×9.6=288

Means each cup contain 9.6 oz water that is enough for 30 guests.

There will be 1 cup water available for guests, that has 9.6 ounce water.

Ratio basically compares quantities, that means it shows the value of one quantity with respect to the other quantity.

If a and b are two values, their ratio will be a:b,

Given that,

Total number of bottles = 24,

Capacity of one bottle = 12 ounces,

And total number of guests = 30.

Capacity of all 24 bottles = 24×12 = 288

Since, there are 30 guests,

So 1 guest will get = 288/30 ounce water = 9.6 ounce water.

So 1 cup water has 9.6 ounce water.

Answer:

26.5 units²

Step-by-step explanation:

I am splitting the figure into a rectangle and two triangles to make this easier for me.

The rectangle is b•h so 5•4 = 20 units²

Area of triangle=1/2bh

The left triangle is [tex]\frac{1}{2}[/tex](3•3) ---> [tex]\frac{1}{2}[/tex](9) ---> 4.5 units²

The right triangle is [tex]\frac{1}{2}[/tex](2•2) --->[tex]\frac{1}{2}[/tex](4) ---> 2 units²

Then add it all up: 20+4.5+2 = 26.5 units²

Answer:

$2399.99

Step-by-step explanation:

the price of the tv is discounted by 25%

that is the same as saying the tv is 75% of its original price

so we take $1799.99/75 to see what one percent of the price is

$1799.99/75=23.9998

then we take 23.9998*100 to see what the original price was

23.9998*100=2399.986667 and then we round to the nearest hundredth

so 2399.99
