The area of a rectangle is 72^9^6 square yards. The length of the rectangle is 8^3^4 yards. What is the width of the rectangle i
Andrei [34K]

Answer:

Step-by-step explanation:

As we know the area of a rectangle = The length* The width

Given that:

  • The area: 72^{9^{6} }
  • The length: 8^{3^{4} }

=> The width= 72^{9^{6} } : 8^{3^{4} }  

= 72^{3^{12} } : 8^{3^{4} }

= (9*8)^{3^{12} } : 8^{3^{4} }

= 9^{3^{12} } * (8^{3^{12} } : 8^{3^{4} }  )

= 9^{3^{12} }8^{3^{8} } feet

I really need help with this since I have a math test tomorrow, I'd really appreciate it if someone could help.
Elza [17]
Ok first of all, I EXTREMELY appreciate your use of parenthesis. Ok so first just raise both sides to the power of 1/2.

(\frac{3}{8})^{x}=\frac{8}{11}

You'll see why I didn't include a negative. Then apply the log base 3/8 and you get

x =   log_{ \frac{3}{8} }( \frac{8}{11} )
Then you split the log up and you get
x =  log_{ \frac{3}{8} }(8)  -  log_{ \frac{3}{8} }(11)
You couldn't put a negative value for a log. That is why I excluded the negative part of the sqrt.

Listed below are the measured radiation emissions​ (in W/kg) corresponding to cell​ phones: A,​ B, C,​ D, E,​ F, G,​ H, I,​ J, a
Sophie [7]

Answer: a. Mean = 0.696364

b. Median = 0.64

c. Midrange = 0.895

d. There is no Mode

e. 2. The maximun data value is the most relevant statistic, because it is closest to the limit of 1.6W/kg and that cell should be avoided.

Step-by-step explanation:

a) Mean is an average number of the data set, calculated by the sum of all the value divided by the quantity of the set:

mean = \frac{0.75+0.22+1.23+0.64+0.54+0.24+0.81+1.57+0.29+1.02+0.35}{11}

mean = 0.696364

b) Median is the middle number in the list of numbers. In this case, since there are 11 elements in the set, the middle number is:

sorted numbers of the data set:

0.22 0.24 0.29 0.35 0.54 0.64 0.75 0.81 1.02 1.23 1.57

median = 0.64

c) Midrange is another type of average number. It is calculated as:

midrange = \frac{high+low}{2}

midrange = \frac{1.57+0.22}{2}

midrange = 0.895

d) Mode is the number that appears most often in the list of numbers. For this data set, each number appears only one time, so there is no mode.

Mode = 0

e) According to the question, cell phone radiation is dangerous when it is higher than 1.6W/kg. The cell phone with the maximum data value (1.57 W/kg) should be avoided, since it is too close to the limit described.

So, the measures of center are not the most important statistic to be observed but the maximum data value.

Find the missing angle measure.
ycow [4]

Step-by-step explanation:

The sum of all inner angles in the shape should be 540°

(180° for triangles, 360° for squares and other simple 4-corner-shapes, the pattern is the number of corners minus 2 multiplied by 180°)

we can calculate

540-106-94-135=205

so we got 205 degrees for the two unclear corners and one of them has to be 5° greater.

x is 100°

x is 100°x+5 is 105°

(note that in the subtraction part we could have subtracted 5 more and would be left with 2x=200)
