Answer: B: 24q+48r

Step-by-step explanation: 6(4q+8r)

=(6)(4q+8r)

=(6)(4q)+(6)(8r)

=24q+48r

Answer:

By "make k as a subject", I assume you mean to solve for k?

If that is the case, then the answer is:

k = (c - a) / b

Step-by-step explanation:

Let's solve for k

a/k + b = c/k

Multiply both sides by k:

a + bk = c

Group terms containing k on the left:

bk = c - a

Divide both sides by k:

k = (c - a) / b

Answer:

The slope is 4/5

Step-by-step explanation:

Answer:

22=90 23=15 24=60 25=0.75 26=70 37=$0.58

Step-by-step explanation:

22. So, we can divide 360 kmh by 4 hours

so 360/4 =90

So 90 kmh in 1 hr

23

So, we can divide 3 packages by $15

so 15÷3 = $5

So $5 per package

24  So, we can divide 720 m by 12s

So, 720/12= 60

60 m in 1 s

25

So, we can divide $4.50 by 6

So, we get $0.75

26

So, we can divide 210 words by 3 min

So, 210÷3=70

70 words per minute

27

So, we can divide 23.20 by 40l

So, 23.20÷40 = 0.58

$0.58

Answer:

(0.5)

Step-by-step explanation:

x + y = 5

3x - y = -5

Put "y" on one side to isolate

3x - y = -5

3x = y - 5

3x + 5 = y

Plug "3x + 5" in for "y" in the second equation

x + (3x + 5) = 5

4x + 5 = 5

4x = 0

x = 0

Plug  "0" in for "x" in any one of the equations

0 + y = 5

y = 5

To check, plug in "0" for "x" into the first equation and make sure they get the same answers

3(0) - y = -5

0 - y = -5

y = 5

Answer: y=17

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

52−2y=18

52+−2y=18

−2y+52=18

Step 2: Subtract 52 from both sides.

−2y+52−52=18−52

−2y=−34

Step 3: Divide both sides by -2.

−2y

−2

=

−34

−2

y=17

Answer: I think is a function

Step-by-step explanation:

Answer:

9.43 cm³

Step-by-step explanation:

Given that the surface area of the spherical scoop is 36π cm², we find its radius. The surface area of a sphere, A = 4πr² where r = radius

36π cm² = 4πr²

r² = 36π cm²/4π

r² = 9 cm²

r = √(9 cm²)

r = 3 cm

So, the volume of the spherical scoop of ice cream is thus V = 4πr³/3

= 4π(3 cm)³/3

= 4π(9 cm³)

= 36π cm³

The volume of the ice cream cone is V' = πr²h/3 where r = radius of cone = radius of spherical scoop = 3cm and h = height of cone = 11 cm

V' = π(3 cm)² × 11 cm/3

= 9π cm² × 11 cm/3

= 33π cm³

So, the volume of ice cream that will overflow is thus V - V' = 36π cm³ - 33π cm³

= 3π cm³

= 9.43 cm³

Answer:

The correct answer is B.

Step-by-step explanation:

Any point can be represented in polar form by using the notation:

[tex]A = (r, \theta)[/tex] (1)

And any polar function must satisfy the following definition:

[tex]r = f(\theta)[/tex]

Let [tex]r(\theta) = 4\cdot \cos 2\theta[/tex], where [tex]r[/tex] is the radial distance of any point of the curve from origin and [tex]\theta[/tex] is the direction of any point of the curve with respect to +x semiaxis, measured in radians.

Finally, we proceed to graph the function with the help of a graphing tool and attach the result.

Besides, we must remember that cosine is a bounded function, which means that domain and range in rectangular coordinates are represented by:

[tex]Dom\{f\} = [-4,4][/tex], [tex]Ran\{f\} = [-4,4][/tex]

Then, the correct answer is B.

Answer:

$24.7875

Step-by-step explanation:

Step one:

given data

your bill before taxes and tip is $19.83

6% sales tax

tip equal to 19% of the original amount.

Required

The total expenses

Step two:

let the total expenses be y

let us calculate the cost of  tax and the tip

Tax

=6/100*19.83

=0.06*19.83

=$1.1898

Tip

=19/100*19.83

=0.19*19.83

=$3.7677

Total

Y= 19.83 +1.1898 +3.7677

Y= $24.7875

15/2=x/3

15×3/2=x

45/2=x

22.5=x

Answer:

22.5

Step-by-step explanation:

First find out the ratio x : 1

2 / 2 = 1

15 /2 = 7.5

Now you have this ratio

7.5 : 1

Now times each value by 3 to get the answer :

22.5 : 3

x = 22.5
