I ended up with the ages of 12, 3, and 2
if u multiply 12 by 2 u end up with 24 then u add 3 and get 27
but I think i have i worked out wrong
Answer:
The equation that represents this situation is 2c² - 5c - 322 = 0
Step-by-step explanation:
∵ Kenan has c clients
∵ Jeff has five less than twice the number of clients that
Kenan has
- That means multiply c by 2 and then subtract 5 from the
product to find the number of Jeff's clients
∴ Jeff's clients = 2c - 5
∵ The product of the number of clients they have is 322
∴ c × (2c - 5) = 322
- Multiply c by the bracket (2c - 5)
∴ (c)(2c) + (c)(-5) = 322
∴ 2c² + (-5c) = 322
- Remember (+)(-) = (-)
∴ 2c² - 5c = 322
- Subtract 322 from both sides
∴ 2c² - 5c - 322 = 0
The equation that represents this situation is 2c² - 5c - 322 = 0
Well x is an obtuse angle
but the angle e,f,g is an acute angle
Answer:
Two acute angles
Step-by-step explanation:
The right triangle has one 90 degree angle and two acute angles. Since the sum of the angles of a triangle is always 180 degrees... The two sides of the triangle that are by the right angle are called the legs... and the side opposite of the right angle is called the hypotenuse.
Let <em>f</em> and <em>s</em> denote the amounts of the <u>f</u>irst and <u>s</u>econd brands that the chef is going to use.
She wants to end up with 290 mL, so
<em>f</em> + <em>s</em> = 290
Each mL of the first brand contains 0.08 mL of vinegar, and each mL of the second contains 0.13 mL of vinegar. The final mixture should have a concentration of 12% vinegar, so that it contains 0.12 • 290 mL = 34.8 mL of vinegar, and
0.08<em>f</em> + 0.13<em>s</em> = 34.8
Solve for <em>f</em> and <em>s</em> :
<em>f</em> + <em>s</em> = 290 → <em>s</em> = 290 - <em>f</em>
0.08<em>f</em> + 0.13 (290 - <em>f </em>) = 34.8
0.08<em>f</em> + 37.7 - 0.13<em>f</em> = 34.8
0.05<em>f</em> = 2.9
<em>f</em> = 58
<em>s</em> = 290 - 58
<em>s</em> = 232
