Mary bought a shirt on sale for $15. The sales tax was 10%. It's Mary played with a $20 bill, what was her change.

Mathematics

Maurinko [17]3 years ago

The equation is:

$20 - ($15 x 1.10) = x

It would cost $16.50 because the sales tax makes the price 110% of what it used to be or 1.1 times more.

Now you have 20 - 16.5 = x

20 - 16.5 = 3.5.

She got $3.50 in change.

Hope this helps :)

The length of the red line segment is 6, and the length of the blue line segment is 4. how long is the major axis of the ellipse
juin [17]

An ellipse is divided into two axes, the longer axis is the major axis and the shorter axis is the minor axis. The length of the major axis of an ellipse is equal to the sum of two distance: the distance between any point on the ellipse and one on focus and the distance between the same point and the other focus. The focus is the point that helps define an ellipse and every ellipse has two foci. These two distance are also called the red line segment and blue line segment. Given 6 for red line segment and 4 for blue line segment therefore, the length of the major axis of the ellipse is 10.

Kanye and jay wanted to see who could run faster in a minute.They both started in the same spot and ran in different directions.
Lena [83]

Answer:

Kanye run faster.

Step-by-step explanation:

Given that,

Time = 1 min = 60 sec

Suppose, we find the speed of kanye and Jay.

According to number line,

Kanye covers the -160m distance and Jay covers the 140 m distance.

Negative sign shows the opposite direction.

We need to calculate the speed of Kanye

Using formula of speed

v=\dfrac{d}{t}

Where, v = speed

d = distance

t = time

Put the value into the formula

v=\dfrac{160}{60}

v=2.66\ m/s

We need to calculate the speed of Kanye

Using formula of speed

v=\dfrac{d}{t}

Put the value into the formula

v=\dfrac{140}{60}

v=2.33\ m/s

The speed of kanye is more than jay.

Hence, Kanye run faster.

(x^4)^3=(x^3)^4 true or false
telo118 [61]

Step-by-step explanation:

(x^4)^3=(x^3)^4 , true

=> x^(4×3) = x^(3×4) = x^12

13^4 x 13^7= (13^4)^7, false

13^(4+7) = 13^11

(13^4)^7 = 13^(4×7) = 13^28

y^5 x y^0/y^3=(y^2)^1 , true

y^5 x y^0/y^3 = y^(5+0-3) = y^2

(y^2)^1 = y^(2×1) = y^2

q^0 x q^5/q^2=(q^3)^2/q^3, true

q^0 x q^5/q^2= q^(0+5-2)= q^3

(q^3)^2/q^3 = q^(3×2-3) = q^3
