Answer:

A) (7^11)/(4^11)

Step-by-step explanation:

Note that the <em>whole</em> fraction is within the parenthesis, and note that the power is outside. To solve, you must distribute the power to all parts of term within the parenthesis, leading to: (7^11)/(4^11)

Zebras migrate in a circle with a round trip of about 300 miles. They travel at 64 km/h. How many hours does it take zebra to do

Tresset [83]

Answer:

7.5 hours (7 hours and 30 minutes)

Step-by-step explanation:

ok Let's start with 64km/h.

1.6 km=1 mile,

64÷1.6=40miles

so 64km/h changes into 40miles/hour.

Zebras's round trip =300miles,

300/40=7.5

so answer is 7.5 hours.

Draw the graphs of the equations x – y = 1 and 2x + y = 8. Shade the area bounded by these two lines and y-axis. Also, determine

NikAS [45]

Answer:

Using Geometry to answer the question would be the simplest:

Step-by-step explanation:

Remembering the formula for the area of a triangle which is $A=\frac12bh$ . One can then tackle the question by doing the following:

Step 1 Find the y-intercepts

The y-intercepts are found by substituting in $x=0$ .

Which gives you this when you plug it into both equations:

$-y=1\\y=-1\\y=8$

So the y-intercepts for the graphs are $(0,-1)\\$ , and $(0,8)$ respectively.

Now one has to use elimination to solve the problems by adding up the equations we get:

$x-y=1\\2x+y=8\\3x=9\\x=3$

Now to solve for the y component substitute:

$2(3)+y=8\\y=2$

Therefore, the graphs intersect at the following:

$(3,2)$

Now we have our triangle which is accompanied by the graph.

now to solve it we must figure out how long the base is:

$b=8-(-1)\\b=9$

The height must also be accounted for which is the following:

$h=3$

Now the formula can be used:

$A=\frac12bh=\frac12(9)(3)=\frac{27}2\ \text{units}^2$

Find the area of each figure below

Ugo [173]

Answer:

25. $27a^{3}b^{2}$

26. $3\pi x^{3}y$

Step-by-step explanation:

For 25:

$A = \frac{a+b}{2} h$ (area of a trapezoid)

$A=\frac{11a^{2}b+7a^{2}b}{2} *3ab$ (substitute terms)

$= \frac{18a^{2}b}{2}*3ab$ (collect like terms)

$= 9a^{2}b*3ab$ (reduce the fraction by crossing out 2)

$= 27a^{3}b^{2}$ (calculate)

For 26:

$A=\pi r^{2}$ (equation of area of a circle)

$A=\pi (3x^{3} y)^{2}$ (enter the radius)

$= 3\pi x^{3} y$ (communtative property to reorder the terms)
