The original price of a ski jacket was $290. It was on sale at a 25% discount. Arianna had a coupon for an additional 10% off sa
Ivanshal [37]

Answer:

Step-by-step explanation:

If the jacket was discounted at 25%, that means that you get 25% off, right?  What it also means is that you are still paying 75%.  To get to the price of the jacket on sale, multiply the price of the jacket by 75% (as a decimal):

290(.75) = 217.50

That's the price of the jacket when it is 25% off the original price.  If Arianna got an additional 10% off that price, that means she got 10% off but is still paying 90%.  To get to the final price that she paid, multiply the sale price of the jacket by 90% (as a decimal):

217.50(.90) = 195.75

That's what she paid in the end for the jacket (i guess not counting tax...?)

Find the area of a triangle formed by placing the vectors [3, 6] and [7, 1] tail-to-tail.
Usimov [2.4K]

Answer:

a. A=10u^{2}

b. View graph

c. 6.40u

Step-by-step explanation:

knowing that the triangle area is equal to base by heigh between two, then:

A=\frac{bh}{2}=\frac{5*4}{2}=10u^{2}

The length of the longest altitude of your triangle is:

c^{2}=a^{2}+b^{2}=5^{2}+4^{2}=25+16=41\\    c=\sqrt{41}=6.40u

finally it can be seen that the position of the triangle does not matter, as long as the base and heigh are maintained, the area of ​​the triangle will be the same
