What is the BODMAS rule?

According to the BODMAS rule, the brackets have to be solved first followed by powers or roots (i.e. of), then Division, Multiplication, Addition, and at the end Subtraction. Solving any expression is considered correct only if the BODMAS rule or the PEMDAS rule is followed to solve it.

Given here, the expression as (2/3-5/6) / 3/4 = 4-5 /6 × 4/3

                                                                          = -4/18

Answer:

g(x)=0.8x+1.6

Step-by-step explanation:

To do this, you need to isolate the variable y, so that when you input x it will immediately return the value of y.

[tex]-4x-6=-5y+2[/tex]

Subtract 2 from both sides:

[tex]-4x-8=-5y[/tex]

Divide both sides by -5:

[tex]y=0.8x+1.6\\\\g(x)=0.8x+1.6[/tex]

Hope this helps!

Answer:

g (x) = 4/5x + 8/5

Step-by-step explanation:

-4x - 6 = -5y + 2

5y = 4x + 8

y = 4/5x + 8/5

Step-by-step explanation:

pyramid height = cube height , a = h (GIVEN)

We could also represent this function with an equation, A = #r2. We say that the input of
the function, r, is the independent variable and the output of the function, A, is the
dependent variable. We can choose any value for r, and then the value of A depends on
the value of r. We could also represent this function with a table or as a graph. Depending
on the question we investigate, different representations have different advantages. You
may recognize this rule and know that the area of a circle depends on its radius.

Volume of composite is 483  [tex]mm^3[/tex]

Step-by-step explanation:

We need to add the volume of a rectangular prism (7 mm x 12 mm x 3 mm) to a semi-cylinder (of radius 3.5 mm and height 12 mm):

Volume of the prism = 7 x 12 x 3 [tex]mm^3[/tex]  = 252 [tex]mm^3[/tex]

Volume of the semi-cylinder =  [tex]\frac{\pi\,\,R^2\,\,H}{2} = \frac{\pi\,\,(3.5)^2\,\,(12)}{2} =230.907 \,\,mm^3[/tex]

Therefore the sum of both volumes gives:

Use the laws of exponents to express 9-3/2 · 82/3 as a simple fraction. Show the steps in the simplification

Answers

Answer:

4/27

Step-by-step explanation:

The laws of exponent are used for the simplification of expressions with exponential powers. Considering the given expression, the applicable laws of exponents are

a^-x = (1/a)^x

and

a^(x/b) = b√a^x

Hence

9-3/2 · 82/3

= (1/9)^3/2 . 8^2/3

= √(1/9)³ . ∛8²

= (1/3)³ . 2²

= 1/27 . 4

= 4/27

I think it is 9.00113750385

Step-by-step explanation:

Answer:

9 cm

Step-by-step explanation:

The area of a cylinder is V = πr² * h, where V is the volume, r is the radius of the base and h is the height. We want to solve for r. We know the value of V and h, so let's plug those in. We get 3818 = πr² * 15, and when we divide by 15, we get 254.53 = πr². We can approximate 3.14 for π, and when we do so, we get 254.53 = 3.14r². Dividing by 3.14 gets us 81.02 = r², and when we take the square root of the equation, we get r≈9 cm. Hope this helps!

what is the measure of the missing angle​

Answers

Answer:

42°

Step-by-step explanation:

We can see that in one leg of the right triangle we already have a 132 degree obtuse angle given. And since a line is 180 degrees, we can see that the inner acute angle of the right triangle is 180 - 132 = 48 degrees.

And since 3 angles of a triangle adds up to become 180, we can use standard algebra to find: 180 - 90 - 48 = 42 degrees.

Scores on the GRE (Graduate Record Examination) are normally distributed with a mean of 594 and a standard deviation of 96. Use the 68-95-99.7 Rule to find the

percentage of people taking the test who score below 306.

The percentage of people taking the test who score below 306 is

%.

Answers

Answer:

0.15%

Step-by-step explanation:

The Empirical Rule ( 68-95-99.7 Rule) states that almost all data falls within 3 standard deviations of the mean for a normal distribution.  Under the rule:

68% of the data falls within one standard deviation. 95% percent of the data lies within two standard deviations. 99.7% of data fall within three standard deviations

Given that:

mean (μ) = 594 and standard deviation σ = 96

68% of the data falls within μ ± σ.  That is 594 ± 96. 68% fall within 498 and 69095% percent of the data lies within μ ± 2σ. That is 594 ± 2(96). 95% fall within 402 and 78699.7% percent of the data lies within μ ± 3σ. That is 594 ± 3(96). 99.7% fall within 306 and 882

The percentage of people that all fall outside 306 and 882 = 100% - 99.7% = 0.3%. Therefore the percentage of people that are below 306 = 0.3% / 2 = 0.15%
