A municipality has budgeted R80 000 for putting up new street name boards The street name boards cost R134 each. How many new st
ivanzaharov [21]

The Municipality we be able to set up 597 street name boards with R2 left in the budget.

Data;

  • Amount Budgeted = R80,000
  • Cost of each board = R134

<h3>Number of Street Boards in the Budget</h3>

The number of streets boards that can be produced in the budget is calculated by dividing the total amount budgeted by the cost of each street board. This is done mathematically as

x = \frac{80000}{134}\\x = 597.01

We would have a total of 597 street names on the budget with some amount left.

We can calculated this by multiplying 597 by 134 and then subtracting the value from R80,000

597 * 134 = 79998 \\R80,000 - R79998 = R2

The Municipality we be able to set up 597 street name boards with R2 left in the budget.

The graphs arey=(1/3)x^2
and y=3
they intersect at x=3
so the limits are x=0 and 3
to rotate it about y=k, minus k from every function


area=\pi  \int\limits^3_0 {( \frac{1}{3}x^2-3)^2-(3-3)^2 } \, dx
which evaluates to 72/5pi

8x−5x+4−x=Ax+8. Anyone know
lora16 [44]

Answer:

a = \frac{2x-4}{x}

x = \frac{4}{-a+2}

Step-by-step explanation:

Let's solve for a.

8x−5x+4−x=ax+8

Step 1: Flip the equation.

ax+8=2x+4

Step 2: Add -8 to both sides.

ax+8+−8=2x+4+−8

ax=2x−4

Step 3: Divide both sides by x.

Let's solve for x.

8x−5x+4−x=ax+8

Step 1: Add -ax to both sides.

2x+4+−ax=ax+8+−ax

−ax+2x+4=8

Step 2: Add -4 to both sides.

−ax+2x+4+−4=8+−4

−ax+2x=4

Step 3: Factor out variable x.

x(−a+2)=4

Step 4: Divide both sides by -a+2.

Hope this helps!
