Gerald can complete a math assignment in 2 hours and a physics assignment in 1 hour. If he has 8 hours to complete a set of assi

gnments, how many math assignments can he complete if he decides to leave the science assignments for the next day? This situation is given by 2x + y = 8, where x is the number of completed math assignments and y is the number of completed science assignments. (x 0, y 0, x and y take only integer values).

If i am reading this question correctly it states "How many math assignments can he complete in 8 hours" leaving out the science assignments because it states he'd do them tomorrow its simple math. 8 divided by 2 which is 4 math assignments he can complete in 8 hours.

Answer: 4 exercises.

Step-by-step explanation:

We know that Gerald has 8 hours to complete a set of assignments if x is the number of math assignments and y is the number of physics assignments, we need to solve the equation:

2x + y = 8

Now, we know that Gerald decides to leave the science assignments for the next day, so on this first day we do not have physics assignments, which implies that y = 0

So now we have the equation 2x = 8

x = 8/2 = 4

x = 4

So we the maximum number that Gerald can complete in 8 hours is equal to 4 (in the situation in which he left the science assignments for the other day)

Find the point, M, that divides segment AB into a ratio of 5:6 if A is at (0, 22) and B is at (11, 0). A) (5, 12) B) (5, 11) C)
amid [387]
\bf \left. \qquad  \right.\textit{internal division of a line segment}&#10;\\\\\\&#10;A(0,22)\qquad B(11,0)\qquad&#10;\qquad 5:6\quad \textit{from A to B}&#10;\\\\\\&#10;\cfrac{AM}{MB} = \cfrac{5}{6}\implies \cfrac{A}{B} = \cfrac{5}{6}\implies 6A=5B\implies 6(0,22)=5(11,0)\\\\&#10;-------------------------------\\\\

\bf { M=\left(\cfrac{\textit{sum of "x" values}}{\textit{sum of ratios}}\quad ,\quad \cfrac{\textit{sum of "y" values}}{\textit{sum of ratios}}\right)}\\\\&#10;-------------------------------\\\\&#10;M=\left(\cfrac{(6\cdot 0)+(5\cdot 11)}{5+6}\quad ,\quad \cfrac{(6\cdot 22)+(5\cdot 0)}{5+6}\right)&#10;\\\\\\&#10;M=\left( \cfrac{55}{11}~~,~~\cfrac{132}{11} \right)

and surely you know what that is.

The graph below shows the total cost for lunch, c, when Will and his friends buy a large salad to share and several slices of pi
Helga [31]

Answer:

2.50 dollars.

Step-by-step explanation:

Given:

Will and his friends buy a large salad to share and several slices of pizza, p.

The graph given shows the total cost for lunch, c and slices of pizza,p.

p is marked horizontally, and c vertically.

Observing the points marked we find that for every increase of one slice of pizza, the cost i.e. c on vertical line increases by 0.50 times vertical grid.

Since each grid equals 5 dollars vertically, we find 1/2 grid increase is equal to increase of 1/2(5 ) =2.50 dollars.

Thus for increase of one slice of pizza, 2.50 dollars cost is increased.

Interval notation, I need help with this and I can't figure out how to do it!!
aliya0001 [1]

To find A∩B, you need to find the values that both data sets include, or where they overlap. Both data sets include the number range of 0 to 3. Because both data sets include 0, but set A does not include 3, the answer is [0, 3).
