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...?)

I don't know at all please help me

Alrighty. 
First we need to make them all simplified. 
So simplified would be \frac{9}{10} times \frac{5}{4} times \frac{5}{2}.
Then we multiply the numerator and the denominator. The final answer is \frac{225}{800}
Simplified is \frac{51}{160}

What is the length of AC
solmaris [256]

Answer:

The answer is the option D AC=126\ units

Step-by-step explanation:

we know that

The triangles EDC and ABC are similar

then

The ratio of their corresponding sides is equal

so

\frac{EC}{CA}=\frac{DE}{AB}

substitute

\frac{x}{140-x}=\frac{9}{81}

solve for x

9x=140-x\\9x+x=140\\x=140/10\\x=14\ units

Find the length of AC

AC=140-x=140-14=126\ units
