-----------------------
1/36 = 6x⁻³

1/36 = 6 x 1/x^3

1/36 = 6/x^3

1/36x^3 = 6

x^3/36 = 6

x^3 = 6 x 36

x^3 = 216

x = ∛216

x = 6

Answer: x = 1

Step-by-step explanation:

Sorry for the delay

Let's solve your equation step-by-step.

1

36

=6x−3

Step 1: Flip the equation.

6x−3=

1

36

Step 2: Solve Exponent.

6x−3=

1

36

log(6x−3)=log(

1

36

)(Take log of both sides)

(x−3)*(log(6))=log(

1

36

)

x−3=

log(

1

36

)

log(6)

x−3=−2

x−3+3=−2+3(Add 3 to both sides)

x=1

An object is traveling at a steady speed of 9 9/10 km/per hour about how long will it take the object to travel 5/1/10 km/per ho
Delicious77 [7]

Answer:

0.52 km

Step-by-step explanation:

We are given that

Speed of object, v=9\frac{9}{10}km/h

Speed of object, v=9+0.9=9.9km/h

Distance travel by object, s=5\frac{1}{10}km

Distance travel by object, s=5+0.1=5.1km

We have to find the time taken by object to travel 5 1/10 km.

We know that

Time=\frac{Distance}{speed}

Using the formula

Time taken by object to travel 5.1 km =\frac{5.1}{9.9} hr

Time taken by object to travel 5.1 km=0.52 hr

The ground temperature at sea level is 60 degrees F. For every 100-foot increase in elevation, the temperature rises 1/10 of one
N76 [4]
<h3>Answer: B. 62 degrees fahrenheit</h3>

====================================================

Explanation:

x = elevation in feet

y = temperature in fahrenheit

The temperature goes up 1/10 = 0.1 degrees for every 100-foot increase of elevation. So the slope is 0.1/100 = 0.001, which tells us how fast the temperature is increasing. In other words, the temperature goes up 0.001 degrees each time the elevation goes up by 1 foot.

The ground temperature is 60 degrees, which is our starting temperature. It's the value of y when x = 0. Therefore, 60 is the y intercept.

We have a slope of m = 0.001 and a y intercept of b = 60. The equation y = mx+b becomes y = 0.1x+60

Now plug in x = 2000 to find the temperature at this elevation

y = 0.001x+60

y = 0.001*2000+60

y = 2+60

y = 62

In a sample of 1000 randomly selected consumers who had opportunities to send in a rebate claim form after purchasing a product,
Vadim26 [7]

Answer: 0.2872

Step-by-step explanation:

Given : In a sample of 1000 randomly selected consumers who had opportunities to send in a rebate claim form after purchasing a product, 260 of these people said they never did so.

i.e. n= 1000 and x= 260

⇒ Sample proportion : \hat{p}=\dfrac{260}{1000}=0.26

z-value for 95% confidence interval : z_c=1.960

Now, an upper confidence bound at the 95% confidence level for the true proportion of such consumers who never apply for a rebate. :-

\hat{p}+ z_c\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}

=0.26+ (1.96)\sqrt{\dfrac{0.26(1-0.26)}{1000}}

=0.26+ (1.96)(0.01387)=0.26+0.0271852=0.2871852\approx0.2872

∴ An upper confidence bound at the 95% confidence level for the true proportion of such consumers who never apply for a rebate : 0.2872

Item 5 There are 20 balls in a bag. Ten of the balls are red, 4 are green, and the rest are yellow. Which ratio represents the n
OlgaM077 [116]

Answer:

3:5 <em>the colon is needed to represent the ratio</em>

Step-by-step explanation:

r = 10

g = 4

y = 30 - 14 = 6

y = 6

so ratio of total balls is 10:4:6

and ratio of y:r is

6:10

simply by dividing by 2

3:5
