Answer:

C

Step-by-step explanation:

Let's find the area of each of the two circles.

First Circle:

The first circle has a diameter of 10 inches. That means the radius is 5 inches. So, its area is:

[tex]A=\pi r^2\\A=\pi (5)^2\\A=25\pi[/tex]

Second Circle:

The second circle has a diameter twice that of the first. So, the diameter is 20 inches. This means that the radius is 10 inches. Find the area:

[tex]A=\pi r^2\\A=\pi (10)^2\\A=100\pi[/tex]

Now, find the ratio between them by dividing:

[tex]\frac{\text{Smaller}}{\text{Larger}}=\frac{25\pi}{100\pi}[/tex]

Simplify:

[tex]\frac{\text{Smaller}}{\text{Larger}}=\frac{1}{4}[/tex]

1/4 is the same as 1:4

So, our answer is C      :)

Answer:

A.-8

Step-by-step explanation:

The greater the slope the steeper the line.

In order to determine which line is closer to vertical, we have to consider the absolute values, because the slope can be positive or negative.

Therefore, the steepest is -8.

Answer:

2*x^4*z^3

Step-by-step explanation:

To answer this kind of question, you first start rearranging the terms in the numerator and denominator, so you don't get confused.

3x^3 * 4x^3 * z^4 / 2x * x * 3z

Now you multiply like parts in the numerator and denominator to keep it simple.

(3x^3 * 4x^3) * z^4 / (2x * x) * 3z

3x^3 * 4x^3 = 12x^6

2x * x = 2x^2

12x^6 * z^4 / 2x^2 * 3z

Now divide like terms that are in the numerator and denominator so multiplying later will be easier.

12x^6 / 2x ^ 2 * z^4 / 3z

12x^6 / 2x^2 = 6x^4

z^4/3z = z^3 / 3

Now you multiply both terms,

6x^4 * z^3/3

2*x^4*z^3

Answer:

Volume of the hemisphere = [tex]\frac{2}{3}\pi r^{3}[/tex]

Step-by-step explanation:

It's a picture of a globe and a globe of the Earth is in the shape of a sphere.

We know equator divides the earth into two equal halves and these equal halves are called as "hemisphere".

Therefore, a line joining the two extreme points of the diameter of the Earth divides the Earth into two hemispheres.

If the radius of the Earth is 'r',

Explanation:

The portion below the x axis is when f(x) is negative. This happens on the interval [tex]-5 < x < 3[/tex]. Note how -5 and 3 are the x intercepts or roots. So because f(x) is negative when [tex]-5 < x < 3[/tex] we can say f(x) is negative over the interval (-5, 3). This is interval notation and not ordered pair notation.

----------

The function f(x) is positive in two places. When x < -5 and when x > 3. This is where the purple parabola is above the x axis.

The x < -5 portion converts to the interval notation (−∞,−5)

The x > 3 portion converts to the interval notation (3,∞)

The function is positive over the interval (3,∞) and interval (−∞,−5) while negative over interval (−5,3) so options (B),(C), and (D) will be correct.

A graph is a diagram that shows the fluctuation of one variable in relation to one or more other variables.

In order to plot the graph, we need to find out y's values corresponding to x's value

After that, we need to substitute the values of x's and y's into the coordinate geometry.

If we look at the graph

The value of graph is positive after x = 3 and it is positive before x = -5

Let's say the graph is going infinitely in both directions.

Then the function is positive over the interval (3,∞) and interval (−∞,−5).

The function is negative from x = -5 to 3 so it will be negative over that.

Hence "The function is positive over the interval (3,∞) and interval (−∞,−5) while negative over interval (−5,3)".

A number system is a mathematical system for representing numbers, that is, quantities.

Thus, the numbers are writing symbols that allow a mental representation of a certain quantity, as well as the different mathematical operations that arise from said quantities.

Otherwise, that is, if the numbers did not exist, the representation of quantities would be very limited.

It also would only abstain from the existence or nonexistence of a certain thing or situation.

Answer: C 165

Step-by-step explanation:

Answer:

28.3 square meters.

Step-by-step explanation:

So we know that the radius of the circle is 3 meters. With that, we can figure out the area of the circle.

The area of a circle is given by the formula:

[tex]A=\pi r^2[/tex]

Plug in 3 for r:

[tex]A=\pi (3)^2[/tex]

Square the number:

[tex]A=9\pi[/tex]

Use a calculator. Approximate:

[tex]A\approx28.2743\approx28.3[/tex]

Therefore, the area of the circle is approximately 28.3 square meters.

Answer:

28.3 m²

Step-by-step explanation:

The area of a circle can be found using the following formula.

[tex]a=\pi r^2[/tex]

We know the radius of the circle is 3 meters. We can substitute 3 m in for the variable, r.

[tex]a= \pi (3m)^2[/tex]

Evaluate the exponent.

(3m)² = 3m * 3m= 9 m²

[tex]a= \pi (9 m^2)[/tex]

Multiply pi and 9 meters squared.

9 m² * π = 28.2743339 m²

[tex]a=28.2743339 m^2[/tex]

Round to the nearest tenth. The 7 in the hundredth place tells us to round the 2 in the tenth place to an 3

[tex]a\approx 28.3 m^2[/tex].

The area is approximately 28.3 square meters.

Answer:

97%

Step-by-step explanation:

89%+98%+96%+?=95×4

283+?=380

?=380-283

?=97%

The lowest score Olivia can get on her fourth test is 97%.

The average score can be determined by dividing the sum of the four scores by the total number of tests taken.

The first step is to determine the sum of the three scores Olivia already has.

Sum of scores = 89 + 98 + 96 = 283%

The second step is to multiply 95 x 4. 95% x 4 = 380%

The third step is to subtract 283% by 380%. 380% - 283% = 97%

Answer:

[tex]\Huge \boxed{\mathrm{52\°}}[/tex]

Step-by-step explanation:

Complementary angles add up to 90 degrees.

There are two angles in this case.

Let the first angle be x.

Let the second angle be x+14.

The sum of these two angles is 90.

x + x + 14 = 90

Combine like terms.

2x + 14 = 90

Subtract 14 from both sides.

2x = 76

Divide both sides by 2.

x = 38

Let x = 38 for the second angle.

38 + 14 = 52

The two angles are 52 degrees and 38 degrees.

52 degrees is 14 degrees more than complementary angle.

Answer:

[tex]\huge\boxed{ Angle = 52\ degrees}[/tex]

Step-by-step explanation:

Complementary angles add up to 90 degrees

So, Let the first angle be x then the second angle will be x + 14

Given condition is:

x + x + 14 = 90

2x + 14 = 90

Subtracting 14 to both sides

2x = 90 - 14

2x = 76

Dividing both sides by 2

x = 38

So, the second angle that is 14 degrees more than 38

=> Second Angle = 38 + 14

=> Second Angle = 52 degrees

We note that a rational number is one that can be expressed as a ratio of two integers a and b

An irrational number is one that cannot be expressed as a ratio of two integers. Example of an irrational number is √3

Also an irrational number divided by a rational number is an irrational number, therefore, we have, the expressions without irrational numbers, which are;

Answer:

El complemento de un ángulo de 39°, mide  51°

La amplitud de m, como suplemento es de 36°

Si lo tomamos como ángulo conjugado, es de 217°

Step-by-step explanation:

Ángulos completarios → Aquellos que sumados, me dan 90°

Ángulos complementarios → Aquellos que sumados, me dan 180°

Angulos complementarios entonces, son:

A y C (sumados, dan 90° → 25 + 65)

Angulos suplementarios entonces, son:

A y B (sumados, dan 180° → 25 + 155)

D y E (sumados, dan 180° → 30 + 150)

Complemento de un ángulo de 39° → Ya vimos que su suma debe dar 90°, por lo que el complemento mide: 90 - 39 = 51°

Si la amplitud del ángulo R es 143°, la del ángulo m, será 37°. Sería el ángulo suplementario a R.

No podríamos tener un complemento porque estamos en valores a 90°, pero también se podría obtener otro ángulo cuya amplitud sea de 217°, en este caso ambos ángulos suman 360°, se los llama angulos conjugados.

The domain is {x∈R| x≠−2}

The range is {y∈R| y≠−5}

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

Explanation:

Using the function, we can factor the numerator to get

x^2-x-6 = (x-3)(x+2)

Then the (x+2) terms cancel out leaving x-3 only

Therefore, f(x) simplifies to f(x) = x-3.

This produces the straight line graph that is shown. But there's a hole at (-2,-5)

Why is this? It's because plugging x = -2 into the original equation (before you simplify) leads to a division by zero error.

The denominator x+2 becomes -2+2 = 0 and we can't divide by zero.

If we plugged x = -2 into the simplified version of f(x), then we have

f(x) = x-3

f(-2) = -2-3

f(-2) = -5

Showing why the hole is at (-2,-5)

There is no way that x can equal -2, so this is why we kick it out of the domain. Similarly, there's no way to get to y = -5, and this value is kicked out of the range.

The notation x∈R means that x is in the real number set. Saying  {x∈R| x≠−2} means x is any real number but -2. The range is a similar story but we kick out -5 instead.

Answer:

a. 5 represents the number of calories that come from other ingredients.

b. Neither 8 nor 3 satisfy the given equation, so neither 8 nor 3 can be the solution to the equation.

c. c = 5.5

Step-by-step explanation:

We are given the equation:

[tex]4c + 5 = 27[/tex]

Where [tex]c[/tex] represents the grams of carbohydrates

27 is the total number of calories that are received by the granola bite.

4 is the number of calories from 1 gram of carbohydrates and

5 is the number of calories that are received from other ingredients.

Answer of Part a:

5 is the number of calories that are received from other ingredients.

Part b:

Let us take left hand side (LHS) and put values of c = 8 and 3 one by one.

So, LHS becomes:

4 \times 8 + 5 = 37 [tex]\neq RHS\ i.e.\ 27[/tex]

4 \times 3 + 5 = 17 [tex]\neq RHS\ i.e.\ 27[/tex]

So, Priya is correct that neither 8 or 3 could be solution.

Part c:

[tex]4c + 5 = 27\\\Rightarrow 4c = 22\\\Rightarrow \bold{c = 5.5}[/tex]

So, solution to the equation is: c = 5.5
