You can just subtract 6% from 30% to get the correct percentage decrease because a sales tax is added to the price. 

30%-6%= 24%

Convert that to a decimal.

24%= .24

50*.24= 12

50-12= 38

HEEEEEEEEEEEEEEEEEEEEELP!!!! A line y=mx+b passes through point (16, −10) and is parallel to y=−34x+8.
ycow [4]

Answer:

b=2

Step-by-step explanation:

We know that the line passes through the point (16, -10).

And we also know that it is parallel to y=-\frac{3}{4}x+8

Notice that the slope of this line is -3/4

Remember that parallel lines have the same slope.

Therefore, the slope of our new line is also -3/4

Now, we can use the point-slope form:

y-y_1=m(x-x_1)

Where <em>m</em> is the slope and (x₁, y₁) is a point.

So, let’s substitute -3/4 for <em>m</em> and (16, -10) for (x₁, y₁). This yields:

y-(-10)=-\frac{3}{4}(x-16)

Distribute:

y-(-10)=-\frac{3}{4}x+12

Simplify:

y+10=-\frac{3}{4}x+12

Subtract 10 from both sides:

y=-\frac{3}{4}x+2

This is in the form <em>y=mx+b</em>.

Therefore, our <em>b</em> is 2.

And our final answer is 2.

What is the circumference of the half circle?
Gelneren [198K]

Answer:

4π cm

Step-by-step explanation:

<u>GIVEN :-</u>

  • Diameter of half circle = 8cm

<u>TO FIND :-</u>

  • Circumference of half circle

<u>FACTS TO KNOW BEFORE SOLVING :-</u>

Circumference of a circle with radius 'r' is = 2\pi r

⇒ Circumference of half-circle with radius 'r' = \frac{2\pi r}{2} = \pi r

<u>SOLUTION :-</u>

Radius = \frac{Diameter}{2} = \frac{8}{2} = 4

So , Circumference of half-circle = \pi \times 4 = 4\pi cm

A football coach is trying to decide: When a team is ahead late in the game,
ddd [48]

Divide the number of wins by total games for each type of defense:

Regular defense = 41 /50 = 0.82

Prevent Defense = 32/50 = 0.64

The decimal is higher for regular defense, so it is more likely to win by playing regular defense.

The last choice is the right one.
