Which expression is equivalent to the given expression? 3(x-7)+4(x^2-2x+9)

Answer: y= [tex]\frac{-3}{1}[/tex]x-4

Step-by-step explanation:

y=mx+b

slope= -3/1

y intercept (the y intercept is where the line intercepts the y axis) = -4

y= [tex]\frac{-3}{1}[/tex]x-4

I am not a professional, simply using prior knowledge.

Answer:

$117

Step-by-step explanation:

39 x 3 or 40+40+40-3

Answer:

$39 x 3 = $117

Step-by-step explanation:

With this problem, we can see that 3 total people went out to eat, meaning that the bill was divided 3 ways evenly. This means that each person paid $39, and to find the grand total then we just need to multiply that number by 3. This will give you an equation of $39 x 3 = $117. $117 was the grand total of the bill. Hope this helps!

Answer:

The tip will be $6.30

Answer:

65.97m³

Step-by-step explanation:

This is a right circular cone, so we will be using V = (1/3)(π)(r²)h

r = radius = 3m

h = height = 7m

V = (1/3)(π)(3m²)(7m) = 65.97m³

The bracket means to multiply.

Answer:

The area of the shaded portion is 123 cm^2

Step-by-step explanation:

Here, we want to find the area of the shaded portion

To find this, we subtract the area of the smaller inner rectangle from that of the outside bigger one

Mathematically, the area of a rectangle at any point in time is length * width

For the bigger one, we have;16 * 9 = 144 cm^2

For the smaller inner one, we have ;3 * 7 = 21 cm^2

The area of the shaded portion which is the difference is;

144-21 = 123 cm^2

Answer:

5

Step-by-step explanation:

The slope is 5 because the equation is y = 200-5x where 5 is the slope because it is the rate of change.

Answer:

910

Step-by-step explanation:

From the given information;

Suppose that everyone served together;

Then, we have:

= C(8,3) × C(6,3)

= [tex]\dfrac{8!}{3!(8-3)!}\times \dfrac{6!}{3!(6-3)!}[/tex]

= [tex]\dfrac{8!}{3!(5)!}\times \dfrac{6!}{3!(3)!}[/tex]

= 1120

But since 1 man and 1 woman refuses to serve together;

Then:

The combination will be:

= C(7,2) × C(5,2)

= [tex]\dfrac{7!}{2!(7-2)!}\times \dfrac{5!}{2!(5-2)!}[/tex]

= [tex]\dfrac{7!}{2!(5)!}\times \dfrac{5!}{2!(3)!}[/tex]

= 210

∴

1120-210 = 910

Thus, the number of ways committee can be formed = 910

Answer :6x + 5y = 30

5y = 30 - 6x

y = 6 - (6/5) x

So slope = -6/5

Perpendicular line has slope 5/6   (product of the slopes is -1)

So y = 5/6 x            +   b

Passed through (-6, -7) so           -7  =   -5  + b

Sp b = -2

So y = (5/6)x - 2

Answer:

324 miles

Step-by-step explanation:

540/5=108 per hour

108*3=324

Answer:

324

Step-by-step explanation:

Take x as the number of hours.

5x=540

x=108

Then multiply x by 3 so that you have 3 hours rather than 1, doing the same to the other side of the equation, so they stay equal.

3x=324

Answer:

3?

Step-by-step explanation:

First I added 20 dollars to 2.50 and I got 22.50 than  I divided 67.50 / 22.50 which gave me 3, so I guess the answer is 3. Hope this helped!

Answer:

4329 softballs

Step-by-step explanation:

To find the number of softballs that will fit into the container, we first find the volume of the softball. Since it is a sphere, its volume V = 4πr³/3 where r = radius = d/2 where d = diameter of softball.

So, V = 4π(d/2)³/3 = πd³/6

Since d = 8.3 in,

V =  πd³/6 =  π(8.3 in)³/6 = π × 571.787 in³/6 = 299.39 in³

The volume of the box, V' = 15 × 10 × 5 ft³ = 750 ft³ = 750 × (12 in)³ = 750 × 1,728 in³ = 1,296,000

So, for n softball to fit, its volume must equal the volume of the storage unit.

The volume of n softballs is nV.

For the softballs to fit, V' = nV

n = V'/V

= 1,296,000 in³/299.39 in³

= 4328.8 softballs

≅ 4329 softballs since we cannot have a decimal number of softballs.

Answer:

Susan's dog weighs 9.75 pounds

Step-by-step explanation:

Given

The weight of Susan's cat = 3 pounds

Susan's dog weighs 3 1/4 or 13/4 times as much as her cat.

To determine

The weight of Susan's dog = ?

As the weight of Susan's cat = 3 pounds

Given that Susan's dog weighs 3 1/4 or 13/4 times as much as her cat. so

The weight of Susan's dog = 13/4 of 3

                                             = 13/4 × 3

                                              = 39/4

                                               = 9.75 pounds

Therefore, Susan's dog weighs 9.75 pounds
