C) 239.99 * 0,4 = 95.99.
We multiply by 0.4 because when you remove 60% from the price, you are left with 40% or 0.4.
Answer: the answer is C
Well if you follow PEMDAS you would have to do the parentheses first but you can’t subtract 18 from a variable (Z) so then you move on to the 2 and you have to do the opposite so you don’t multiply both sides by 2 you have to divide both sides by 2. And that’s how u get C
Step-by-step explanation:
<u>Given function:</u>
<u>Find x intercepts:</u>
- 2x² + 14x - 16 = 0
- x² + 7x - 8 = 0
- x² - 1 + 7x - 7 = 0
- (x - 1)(x + 1) + 7(x - 1) = 0
- (x - 1)(x + 8) = 0
- x = - 8, x = 1
<u>Midpoint of x intercepts:</u>
- 1/2(-8 + 1) = -7/2 = - 3.5
<u>Whether the extreme value is minimum or maximum:</u>
- Its minimum as the leading coefficient is positive
<u>Write in g(midpoint):</u>
- g(-3.5) = 2(-3.5)² + 14(-3.5) - 16 = - 40.5
<u>The vertex is:</u> (- 3.5, - 40.5)
Answer:
Equation: ($26÷4 hours) × 25 hours
Answer: $156.25
Step-by-step explanation:
First, you would have to find out how much she earns per hour, so $26÷4. Then you multiply that by 25.
(26÷4) x 25=$156.25.
(hope this helps :P)
The only way 3 digits can have product 24 is
1 x 3 x 8 = 241 x 4 x 6 = 242 x 2 x 6 = 242 x 3 x 4 = 24
So the digits comprises of 1,3,8 or 1,4,6, or 2,2,6, or 2,3,4
To be divisible by 3 the sum of the digits must be divisible by 3.
1+ 3+ 8=12, 1+ 4+ 6= 11, 2 +2 + 6=10, 2 +3 + 4=9Of those sums of digits, only 12 and 9 are divisible by 3.
So we have ruled out all but integers whose digits consist of1,3,8, and 2,3,4.
Meanwhile they must be odd they either must end in 1 or 3.
The only ones which can end in 1 are 381 and 831.
The others must end in 3.
They must be greater than 152 which is 225. So the
First digit cannot be 1. So the only way its digits can contain of1,3,8 and close in 3 is to be 813.
The rest must contain of the digits 2,3,4, and the only way they can end in 3 is to be 243 or 423.
So there are precisely five such three-digit integers: 381, 831, 813, 243, and 423.
