Answer:

  216 in³

Step-by-step explanation:

The ratio of volumes is the 3/2 power of the ratio of areas.

  small volume = ((small area)/(large area))^(3/2) × (large volume)

  = (212/1325)^(3/2) × 3375 in³ = (4/25)^(3/2) × 3375 in³ = (8/125)×3375 in³

  small volume = 216 in³

Answer:

rectangular equation, or an equation in rectangular form is an equation composed of variables like xx and yy which can be graphed on a regular Cartesian plane. For example y=4x+3y=4x+3 is a rectangular equation.

A curve in the plane is said to be parameterized if the set of coordinates on the curve, (x,y)(x,y) , are represented as functions of a variable tt .

x=f(t)y=g(t)x=f(t)y=g(t)

Distributive property (-5 is being multiplied to x and - 6)

Addition property of equality (5x is being added in both sides of the equation)

Division property of equality (15 is being divided into both sides of the equation)

We can solve mathematical equations thanks to algebra's inherent characteristics. The algebraic properties are distributive property, addition property of equality, and division property of equality.

Given expressions are:-

-5x + 30 = 10x

Answer: C

Step-by-step explanation:

Now we have to,

find the required value of x.

Let's begin,

→ 3x-2 = 2(x-5)

→ 3x-2 = 2x-10

→ 3x-2x = -10+2

→ x = -8

Hence, value of x is -8.

Answer:

x = -8

Step-by-step explanation:

3x - 2 = 2 ( x + 5

Solve for x.

Let's solve,

3x - 2 = 2 ( x + 5 )

Step 1:- Distribute 2.

3x - 2 = 2 × x + 2 × 5

3x - 2 = 2x - 10

Step 2 :- Move constant to the right-hand and change their sign.

3x = 2x - 10 + 2

Step 3:- Add -10 and 2.

3x = 2x - 8

Step 4 :- Move variable to the left-hand side and change their sign.

3x - 2x = -8

Step 5 :- Subtract 2x from 2x.

x = -8

Hence, value of x = -8.

Answer:

9.5 seconds pass before the object reaches the ground.

Step-by-step explanation:

Height of the ball:

The height of the ball after t seconds is given by the following equation:

[tex]h(t) = -16t^2 + 1444[/tex]

Find how many seconds pass before the object reaches the ground.

This is t for which h(t) = 0. So

[tex]h(t) = -16t^2 + 1444[/tex]

[tex]-16t^2 + 1444 = 0[/tex]

[tex]16t^2 = 1444[/tex]

[tex]t^2 = \frac{1444}{16}[/tex]

[tex]t^2 = 90.25[/tex]

[tex]t = \pm \sqrt{90.25}[/tex]

Since it is time, we only take the positive value.

[tex]t = 9.5[/tex]

9.5 seconds pass before the object reaches the ground.

Answer:

[tex]P(80/100<x<100/100)=0.08[/tex]

Step-by-step explanation:

We are given that

Mean,[tex]\mu=68.5[/tex]%=68.5/100

Standard deviation, [tex]\sigma=8.2[/tex]%=8.2/100

We have to find the probability that a student who wrote the examination had a mark between 80% and 100%.

[tex]P(80/100<x<100/100)=P(\frac{80/100-68.5/100}{8.2/100}<\frac{x-\mu}{\sigma}<\frac{100/100-68.5/100}{8.2/100})[/tex]

[tex]P(80/100<x<100/100)=P(1.40<Z<3.84)[/tex]

We know that

[tex]P(a<Z<b)=P(Z<b)-P(Z<a)[/tex]

Using the formula

[tex]P(80/100<x<100/100)=P(Z<3.84)-P(Z<1.40)[/tex]

[tex]P(80/100<x<100/100)=0.99994-0.91924[/tex]

[tex]P(80/100<x<100/100)=0.0807\approx 0.08[/tex]

Answer:

3/2=1.5 sec

Step-by-step explanation:

Equate d=0 and solve the expression, t=-1 and 3/2 but t can't be negative.

The air bubble will reach the surface in 1.5 seconds.

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication and division.

The given expression is d = 3.2(t+1)(2t - 3) where d is the height of the aquarium and t is the time taken by the bubbles to come to the surface.

When the bubble will come to the surface height D becomes zero.

d = 3.2(t+1)(2t - 3)

3.2(t+1)(2t - 3) = 0

t + 1 = 0  and  2t - 3 = 0

t = -1  and t = 3 / 2 = 1.5

Therefore, the air bubble will reach the surface in 1.5 seconds.

Answer:

so required angles are 50.7°and 129.3°

Step-by-step explanation:

Let the angle be x

another angle = x + 78.6°

so,

x + x + 78.6° = 180° {being sum of supplementary angle}

so, 2x + 78.6° = 180°

or, 2x = 180° - 78.6°

or, x = 101.4/2

so, x = 50.7°

so another angle = x + 78.6°

= 50.7° + 78.6°

= 129.3°

Answer:

Step-by-step explanation:

We know:

All triangles have internal angles that add up to 180°.

And

All right triangles have acute angles that up to 90°.

Therefore

x + 30° + 90° = 180°

x + 120° = 180°     |subtract 120° from both sides

x + 120° - 120° = 180° - 120°

x + 30° = 90°     |subtract 30° from both sides

x + 30° - 30° = 90° - 30°

The size of angle x will be 60°

It is a plane figure with three straight sides and three angles.

The steps are as follow:

z = 90°

y = 30°

x = ?

∴ x + y + z = 180°

∴ x + 30 + 90 = 180

∴ x + 120 = 180

∴ x = 60°

So the size of angle x will be 60°

The brand B must be eliminated since it has highest percentage 4.79%.

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

Here,

Brand A percentage = 40/913 ×100

= 4.38%

Brand B percentage = 38/792 ×100

= 4.79%

Brand C percentage = 21/626 ×100

Answer:

We can conclude that the population mean work week for men exceed 40 hours.

Step-by-step explanation:

Given that :

Mean, xbar = 45.6

Standard deviation, s = 14.6

Sample size, n = 893

x = 40

Hypothesis :

H0 : μ = 40

H1 : μ > 40

Using test statistic for one sample t test :

Test statistic = (xbar - μ) ÷ (s/√(n))

Test statistic = (45.6 - 40) ÷ (14.6/√(893))

T = (5.6 / 0.4885703)

Test statistic = 11.46

Using the Pvalue approach :

Reject H0 : if Pvalue < α

Pvalue for test statistic of 11.46 will be approximately 0 (Extremely low)

Hence, Pvalue < α ; We reject H0 ; and conclude that population mean work week for men exceed 40 hours
