Answer:

She could make 5 of each type.

Step-by-step explanation:

If x is the number of 0.5 pound hamburgers and y is the number of 0.25 pound hamburgers:

0.5x + 0.25y = 3.75

Divide through by 0.25:

2x + y = 15

Some whole numbers which fit this relation  are x = 5 and y = 5.

Answer:

  • See below

Step-by-step explanation:

<u>Given:</u>

  • Number of 0.5-pound is a
  • Number of 0.25-pound is b
  • Total weight is 3.75 pounds

<u>Equation for the number of hamburgers:</u>

  • 0.5a + 0.25b = 3.75

simplified to:

  • 2a + b = 15

<u>Minimum number of each size is zero, then the maximum possible number is:</u>

  • a = 0 ⇒ b = 15
  • b = 0 ⇒ 2a = 15 ⇒ a = 7 so b can't be zero, 2*7 + b = 15 ⇒ b = 1

<u>So possible numbers are within the range:</u>

  • 0.5 pound ⇒ 0 to 7
  • 0.25 pound ⇒ 1 to 15

Beth purchased a computer, and its value depreciated exponentially each year. Beth will sketch a graph of the situation, where x
Katyanochek1 [597]

What is x?

It is the number of years since purchase. Can this be negative?

NO! Years cannot be negative. So we disregard negative x-axis.


What is y?

It is the value of the computer at that year. A computer starts off with a positive value (y axis) and depreciates to 0 after some years. Can this be negative?

NO! At 0 value, the computer is worth nothing! There is nothing known as <em>negative </em>value. So we disregard negative y-axis.


The graph that Beth will sketch will have to be in the 1st quadrant (positive x-axis & positive y-axis).

ANSWER: Quadrant I only

Find all solutions in the region [0,2pi) for the equation cos^2(2x)-sin^2(2x)=0
Lynna [10]
\cos^{2}(2x)-\sin^{2}(2x)=0
\rightarrow \sin^{2}(2x)=\cos^{2}(2x)
\rightarrow \frac{\sin^{2}(2x)}{\cos^{2}(2x)}=1
\rightarrow \tan^{2}(2x)=1
\rightarrow \tan(2x)=\pm 1

2x can range anywhere in [0, 4\pi)
So:
\rightarrow 2x=\frac{\pi}{4}, \frac{3\pi}{4}, \frac{5\pi}{4}, \frac{7\pi}{4}, \frac{9\pi}{4}, \frac{11\pi}{4}, \frac{13\pi}{4}, \frac{15\pi}{4}
\rightarrow x=\frac{\pi}{8}, \frac{3\pi}{8}, \frac{5\pi}{8}, \frac{7\pi}{8}, \frac{9\pi}{8}, \frac{11\pi}{8}, \frac{13\pi}{8}, \frac{15\pi}{8}

solve using a system of equations. a pharmacist wants to mix two solutions to obtain 350 cc of a solution that has a 14% concent
Pavlova-9 [17]

Answer:

105 cc of 7% solution

245 cc of 17% solution

Step-by-step explanation:

If x = volume of 7% solution, and y = volume of 17% solution, then:

x + y = 350

0.07x + 0.17y = 0.14(350)

Solve with substitution:

0.07x + 0.17(350 − x) = 0.14(350)

0.07x + 59.5 − 0.17x = 49

10.5 = 0.10x

x = 105

y = 245
