Answer:

C) 136 inches.

Step-by-step explanation:

To find this just do the equation:

170 x 0.8 = ?

This equation tells use how much 80% of 170 is. Also, before doing an equation like this, change the percentage into a decimal like 80% to 0.8.

So,

170 x 0.8 = 136

170 + 136 = 306

So the boat is 306 inches.

Answer:

306 inches

Step-by-step explanation:

80% = 0.8

170 inches × 80% = 170 × 0.8 = 136

The truck is 80% longer than the boat. 80% of the boat is 136.

So, the boat is 170 inches + 136 inches = 306 inches.

PKE is a triangle and its interior angles therefor sum to 180deg:

$P+K+E=180$
$90+(x+6)+2x=180$
$96+3x=180$
$3x=84$
$x=\frac{84}{3}=28deg$

Answer:

option c

Step-by-step explanation:

first, find the y-intercept:

the y-intercept is the point where the line intersects at the y-axis, in this case, at 3.

therefore, we can rule out all options except c, sincee the y-intercept is 3

hope this helps :)

Find the maximum and the minimum value of the following objective function, and the value of x and y at which they occur. The f

kumpel [21]

Answer:

The maximum value of the objective function is 112 when x = 0 and y = 7.

Step-by-step explanation:

Given the constraints:

5x+3y≤37, 3x+5y≤35, x≥0, y≥0

Plotting the above constraints using geogebra online graphing tool, we get the solution to the constraints as:

A(0, 7), B(7.4, 0), C(5, 4) and D(0, 0)

The objective function is given as E =2x+16y, therefore:

At point A(0, 7): E = 2(0) + 16(7) = 112

At point B(7.4, 0): E = 2(7.4) + 16(0) = 14.8

At point C(5, 4): E = 2(5) + 16(4) = 74

At point D(0, 0): E = 2(0) + 16(0) = 0

Therefore the maximum value of the objective function is at A(0, 7).

The maximum value of the objective function is 112 when x = 0 and y = 7.
