Which measurement is most likely to be used to determine the diameter of the well cap?

Answer:

x > [tex]\frac{1}{5}[/tex]

Step-by-step explanation:

[tex]\frac{5(9-x)}{3+1}<11[/tex]

Add 3 and 1 to get 4.

[tex]\frac{5(9-x)}{4}<11[/tex]

Use the distributive property to multiply 5 by 9−x.

[tex]\frac{45-5x}{4}<11[/tex]

Subtract  45/5 from both sides.

[tex]-\frac{5}{4}x<11-\frac{45}{4}[/tex]

Since 44/4 and 45/4 have the same denominator, subtract them by subtracting their numerators.

[tex]-\frac{5}{4} x<-\frac{1}{4}[/tex]

Multiply both sides by -4/5, the reciprocal of -5/4. Since -5/4 is negative, the inequality direction is changed.

[tex]x>-\frac{1}{4} (-\frac{4}{5} )[/tex]

Multiply -1/4 times -4/5 by multiplying numerator times numerator and denominator times denominator.

[tex]x>\frac{-(-4)}{4 x 5}[/tex]

[tex]x>\frac{1}{5}[/tex]

Answer:

The daily rate is: 17500 units per day

Step-by-step explanation:

Given

[tex]R = 1700x - 2x^2[/tex]

[tex]\frac{dx}{dt} = 25[/tex]

Required

Find [tex]\frac{dR}{dt}[/tex] when [tex]x = 250[/tex]

We have:

[tex]R = 1700x - 2x^2[/tex]

Differentiate both sides with respect to time

[tex]\frac{dR}{dt} = 1700\frac{dx}{dt} - 4x\frac{dx}{dt}[/tex]

Factorize

[tex]\frac{dR}{dt} = (1700- 4x)\frac{dx}{dt}[/tex]

Substitute: [tex]\frac{dx}{dt} = 25[/tex] and [tex]x = 250[/tex]

[tex]\frac{dR}{dt} = (1700- 4x)\frac{dx}{dt}[/tex]

[tex]\frac{dR}{dt} = (1700- 4*250)*25[/tex]

[tex]\frac{dR}{dt} = (1700- 1000)*25[/tex]

[tex]\frac{dR}{dt} = 700*25[/tex]

[tex]\frac{dR}{dt} = 17500[/tex]

Answer:

  (c)  (0, 6)

Step-by-step explanation:

Conventionally, an "ordered pair" is a pair of items in parentheses, separated by a comma. The items don't have to be numbers. (0, 6) is an ordered pair.

__

Comments on the other answer choices

Curly braces are usually used as delimiters of a set, not an ordered pair.

Three items do not constitute a "pair." Rather, they are a "triple."

Items without any particular indicator of grouping are usually not considered a "pair."

Answer:

Radius of cylinder = 2 inch (Approx.)

Step-by-step explanation:

Given:

Volume of cylinder = 75.4 in³

Height of cylinder = 6 inches

Find;

Radius of cylinder

Computation:

Volume of cylinder = πr²h

Volume of cylinder = (3.14)r²(6)

75.4 = (18.84)r²

(Radius of cylinder )² = 75.4 / 18.84

(Radius of cylinder )² = 4.002123

(Radius of cylinder) = 2

Radius of cylinder = 2 inch (Approx.)

Answer:

will this work or help ?

Step-by-step explanation:

The given equation governs the height versus time of the object. h(0) = 64, so the ground is considered at h = 0. The question is at what time is h = 0? So, set h = 0 and solve for t.

-16t^2 + 48t + 64 = 0

We can divide both sides of this equation by -16 for simpler numbers. We get

t^2 - 3t - 4 = 0

We can factor this equation:

(t - 4)(t + 1) = 0

So, t = 4 and t = -1 are solutions.

But, time must be positive, so t = -1 makes no sense, so we discard it. This leaves

t = 4 sec.

Answer:

A) - 0.8 Ibs

B) There isn't enough information

    The standard deviations of the difference scores is needed

Step-by-step explanation:

N = 110 female first year college students

Mean weight at beginning of study = 130.6 Ib

Mean weight after six ( 6 ) months = 131.4 Ib

standard deviation = 20 pounds

A) Determine the change in the mean weight over the six(6) months period

mean weight at beginning - mean weight after six(6) months

= 130.6 - 131.4

= -0.8 Ibs

B) Determine if there is sufficient information to find a confidence interval

There isn't sufficient information to determine the confidence interval but in other to determine the confidence interval or conduct an estimate You need standard deviations of the difference scores to calculate the standard error of mean

Step-by-step explanation:

The coloured triangle with the blank triangle area =

The blank triangle area =

[(14-10m) x 6.5m]÷2 = 13[tex]m^{2}[/tex]

Answer:

m<A = 98.25

m<B = 81.75

m<C = 113

m<D = 113

m<E = 67

Step-by-step explanation:

3x + 12 + 5x - 18 = 180

8x - 6 = 180

8x = 186

x = 23.25

3x + 12

3(23.25) + 12

81.75

5x - 18

5(23.25) - 18

98.25

6y - 5 + 10y - 7 = 180

16y - 12 = 180

16y = 192

y = 12

6y - 5

Answer:

A and C

Step-by-step explanation:

The triangle given has three equal sides and three equal angles.

Since the sum of a triangle = 180°, therefore, each angle equals 60°

Thus, we can conclude that the triangle is an acute triangle because an acute triangle has all three sides measuring less than 90°. This implies that all it's angles are acute angles.

Also, since all its sides are equal and the same as well as it's three angles, based on this, we can equally say the triangle is an equilateral triangle.

The triangle can be referred to as an acute triangle and also as an equilateral triangle.

The complete table is shown in attached figure.

The graph of y = 2x + 3 is shown in attached figure.

What is linear expression?

A linear expression is an algebraic statement where each term is either  constant or variable raised to the first power.

Given that;

The equation is y = 2x + 3

Now, For Complete the table we can calculate as;

For first column;

The value of x = -2

Hence, The value of y is calculated as;

y = 2x + 3

y = 2 × -2 + 3

y = -4 + 3

y = -1

Thus, For first column of table;

x = -2 and y = -1

And, For third column;

The value of x = 0

Hence, The value of y is calculated as;

y = 2x + 3

y = 2 × 0 + 3

y = 0 + 3

y = 3

Thus, For third column of table;

x = 0 and y = 3

And, For fourth column;

The value of x = 1

Hence, The value of y is calculated as;

y = 2x + 3

y = 2 × 1 + 3

y = 2 + 3

y = 5

Thus, For fourth column of table;

x = 1 and y = 5

And, For sixth column;

The value of x = 3

Hence, The value of y is calculated as;

y = 2x + 3

y = 2 × 3 + 3

y = 6 + 3

y = 9

Thus, For sixth column of table;

x = 3 and y = 9

Thus, The complete table is shown in attached figure.

The graph of y = 2x + 3 is shown in attached figure.

Answer:

Hypotenuse: 41 meters, Long leg: 40 meters, Short leg: 9 meters.

Step-by-step explanation:

According to the statement, we have the following information about the lengths of the right triangle:

Hypotenuse

[tex]3\cdot x + 14[/tex]

Long leg

[tex]3\cdot x + 13[/tex]

Short leg

[tex]x[/tex]

By the Pythagoric Theorem, we have the following expression:

[tex](3\cdot x + 14)^{2} = x^{2} + (3\cdot x + 13)^{2}[/tex] (1)

[tex]9\cdot x^{2}+84\cdot x + 196 = x^{2} + 9\cdot x^{2} + 78\cdot x + 169[/tex]

[tex]9\cdot x^{2} + 84\cdot x + 196 = 10\cdot x^{2} + 78\cdot x +169[/tex]

[tex]x^{2} -6\cdot x -27 = 0[/tex]

[tex](x-9)\cdot (x+3) = 0[/tex]

As length is a positive variable by nature, then the only possible solution is [tex]x = 9[/tex]. Lastly, the side lengths of the right triangle are:

Hypotenuse: 41 meters, Long leg: 40 meters, Short leg: 9 meters.
