Answer:

72 cubic inches

Step-by-step explanation:

A volume of a box can be found using this equation: l x w x h

Length x Width x Height. We're given all 3 of the values, so multiply them together and voila, it's the volume of the given box!

8 x 3 x 3 = 72

Answer:

72in³

Step-by-step explanation:

$V_{ Rectangular Prism}} = \text{length x width x height}$

V = 3in x 3in x 8in

V = 9in² x 8in

V = 72in³

How do you answer a, b and c, answers and also how you worked it out

Kruka [31]

We can either convert to standard form first or convert to a common multiplier, kinda like a common denominator. The latter makes more sense if they wanted the result in scientific notation, but let's do it that way anyway.

4.5 × 10⁴ + 3.8 × 10³ = 45 × 10³ + 3.8 × 10³ = 48.8× 10³ = 48,800

Answer: 48,800

4.5 × 10⁴ - 3.8 × 10³ = 45 × 10³ - 3.8 × 10³ = 41.2× 10³ = 41,200

Answer: 41,200

7.2 × 10⁻³ + 6.3 × 10⁻² = 7.2 × 10⁻³ + 63 × 10⁻³ = 70.2 × 10⁻³

= 7.02 × 10⁻² = 0.0702

Answer: 0.0702

Omg help me please like I just can't right now <br><br> 2x-6y= -12 <br> x+2y=14

steposvetlana [31]

here,

2x-6y= -12

2(x-3y)= -12

x-3y = -6...........eq1

x+2y=14............eq2

we can subtract the above two given equations

we get,

$x - 3y = - 6 \\ x + 2y = 14$

___________

$- 5y = - 20$

so,

y=4

now to find the value of x we have to substitute the value of y in any of the above two equations, I choose eq2

we get,

$x + 2y = 14 \\ x + 2 \times 4 = 14 \\ x + 8 = 14 \\ x = 14 - 8 \\ x = 6$

The random variable X~(30,2^2) <br> Find p(X<33) <br> Find p(X>26)

Ostrovityanka [42]

Answer:

i) P(X<33) = 0.9232

ii) P(X>26) = 0.001

Step-by-step explanation:

Given that the mean of the Population = 30

Given that the standard deviation of the Population = 4

Let 'X' be the Normal distribution

Given that the random variable X = 33

$Z = \frac{x-mean}{S.D}$

$Z = \frac{33-30}{2} = 1.5$ >0

P(X<33) = P( Z<1.5)

= 1- P(Z>1.5)

= 1 - ( 0.5 - A(1.5))

= 0.5 + 0.4232

P(X<33) = 0.9232

Given that the random variable X = 26

$Z = \frac{x-mean}{S.D}$

$Z = \frac{33-26}{2} = 3.5$ >0

P(X>26) = P( Z>3.5)

= 0.5 - A(3.5)

= 0.5 - 0.4990

= 0.001

P(X>26) = 0.001

Help..................

elena-14-01-66 [18.8K]

Triangle has 180 degrees:
180=2m-3+m+4+3m+5
Combine like terms
180 = 6m+6
Subtract 6 from 180
174=6m
Divide by 6
m=29
