Ziv's taxicab ride cost $33. He left a 15% tip.
sergiy2304 [10]

Answer:

Step-by-step explanation:

1. Find 15% of $33 to find the tip.

Find 1%  of $33 (move the decimal over 2 places to the left.        $0.33

2. Multiply the 1% tip by 15%

       33 * 15 =  $4.95  

3. Add $33 and $4.95

          4.95 + 33.00 = $37.95 total

Complete the TABLE of values for x+y=6.
kvasek [131]

Answer:

X        Y

-2       8

-1        7

0        6

1         5

2        4

3        3

Step-by-step explanation:

We have the equation: x+y=6

We want to get this in the form: y=mx+b (or in this case y=x+b)

To do this we need y to be positive and by itself

So we subtract y from both sides and divide by -1 (we divide by -1 because otherwise y would be negative and that does not fit our template of y=x+b)

Doing this we have

-x+6=y

From here we just plug in numbers -2 to 3 which I will assume you know how to do

X        Y

-2       8

-1        7

0        6

1         5

2        4

3        3

Pls help I don’t get any of them
JulijaS [17]

Answer:

Step-by-step explanation:

28.   Area of the circle = πr^{2} where r is the radius of the circle.

       Given diameter = 14m, therefore radius = \frac{14}{2} = 7m

       Now area of the circle = 49\pi ^{2} or = 49 * 3.14 * 3.14 = 483.12m^{2}

29. Volume of cylinder = πr^{2}h = π*1.5^{2} * 3 = 6.75π cu. feet or 21.195 cu. feet

30. A ball resembles a sphere. Volume of the sphere = \frac{4}{3} \pi r^{3}

      Given diameter = 30inches; Therefore, radius = 15 inches

 Now, Volume of the ball = \frac{4}{3} \pi 15^{3} = 4500π cu. inches or 14310 cu.inches

This is Algebra 1 functions and I'm struggling with this one function-
Kitty [74]

Answer:

38

Step-by-step explanation:

f(-9) is the value of f(x) when x = -9. Therefore, f(-9) = 4 from the graph. Doing the same with g(6), we can see that g(6) = 6. Our expression becomes:

-1 * 4 + 7 * 6

= -4 + 42

= 38
