A pair of jeans originally cost $80, but is on sale for 30% off. there is a coupon available for an additional 10% off of the sa

Lady_Fox [76]

30% = 0.3.

0.3*80 = 24, so we know that 30% of 80 is 24.

80 - 24 = 56, so after the sale, the price for a pair of jeans is $56.

10% = 0.1

0.1*56 = 5.6, so with the coupon, we get $5.60 off.

56 - 5.60 = 50.40

The jeans cost $50.40 after the sale and the coupon.

Jay has $8. he wants to buy a book for $7.50. the sales tax is 6%. does he have enough money? explain your reasoning.

antoniya [11.8K]

Yes he does.

If the sales tax is 6%, that means that he has to pay an extra 6 cents for every dollar.

6x7.5=45

$7.50+$0.45=$7.95

Help please with this math ;-; I beg of you

RSB [31]

Answer:

49 - 9π

Step-by-step explanation:

Area of white portion = area of triangle - area of circle

To find the area of the triangle:

The area of a triangle can be calculated using this formula

$A=\frac{bh}{2}$ where b = base length and h = height

The height given is 7m and the base length given is 14m

That being said we plug in the given values into the formula

$\frac{14*7}{2} \\14*7=98\\\frac{98}{2} =49$

Hence, the area of the triangle is 49 sq meters.

To find the area of circle

( note that the area is in terms of pi; shown by the answer choices. )

Formula for area of a circle = $A=\pi r^2$

We are given the diameter ( 6m )

However, we need the radius

To convert diameter to radius we divide by 2

6/2 = 3 so the radius = 3m

Now we plug in 3 into the formula

$A=\pi 3^2\\3^2=9\\A=9\pi$

Remember we do not apply pi because the answer should be in terms of pi.

Now we subtract the two

Area of white portion = 49 - 9π

Hence, the answer is A
