A pair of desiner sneakers was bought for $120. Since they were bought their price had increased by 15%. What is the new price

1 answer:

8 0

The base price is $120. 15% in decimal form is 0.15, to get 15% of 120 you multiply the decimal form of 15% by 120.
0.15 * 120 = 18
Since the price increased by 15 percent, and $18 is 15% of 120, we add 18 to 120, so the answer is

$138

Find the slope of the line whose equation is 4x - 6y = 8.

ss7ja [257]

Answer:

$Slope=\frac{2}{3}$

Step-by-step explanation:

4x - 6y = 8 ⇔ - 6y = -4x + 8 ⇔ y = 4/6x - 8/6 ⇔ y = 2/3x - 4/3

Michelin Tire Company wishes to set a minimum mileage guarantee on its new MX100 tire. Tests reveal the mean mileage is 67,900 w

Keith_Richards [23]

Answer:

The minimum guaranteed mileage is $x = 71489.55$

Step-by-step explanation:

From the question we are told that

The mean is $\mu = 67900$

The standard deviation is $\sigma = 2050$

Generally for the probability to be 4% the minimum guaranteed mileage is evaluated as

$P( X \ge x ) =1- P( \frac{X - \mu }{\sigma } < \frac{ x - 67900 }{ 2050} ) = 0.04$

$\frac{X -\mu}{\sigma } = Z (The \ standardized \ value\ of \ X )$

$P( X \ge x ) =1- P( Z$

=> $P( X \ge x ) = P( Z$

=> $z = \frac{ x - 67900 }{ 2050}$

From the z table, the critical value corresponding to 0.96 to the left of the curve is

$z = 1.751$

$1.751 = \frac{ x - 67900 }{ 2050}$

=> $x = 71489.55$

Question in the link below.

olga_2 [115]

The 5x and the combination of (40° + x) are "vertical angles".
Vertical angles are equal.
So
5x = 40° + x

Subtract 'x' from each side: 4x = 40°

Divide each side by 4 : x = ?

Find the slope of the line (12,-18), (11,12)

telo118 [61]

Answer:

-30

Step-by-step explanation:

To find slope, subtract two y's and then subtract the x's in the same order.

12-(-18)=30=-30

11-12 -1

You could also switch the order like this...

-18-12=-30=-30

12-11 1

As you can see, both of the ways of solving for slope resulted in -30.

Hope this helps!! Have a great day :3
