Which fraction is closest to 1 1/2?

Answer:

I think it would be 2 miles

Step-by-step explanation:

This is because 1/4 of an hour is 15 minutes

so in 15 minutes he swims half a mile

4 x 15 = 60 minutes

so 4 x 1/2 = 2miles

Answer:

3. 147 \(ft^{3}\)  4. \(\frac{160}{3} \pi\) \(ft^{3}\)

Step-by-step explanation:

3. Volume of a square pyramid = \((base.edge.length)^{2}\) × \(\frac{height}{3}\)

Variables:

V = volume

x = base edge length

h = height

V = \(x^{2}\)  × \(\frac{h}{3}\)

x = 7 ft

h = 9 ft

Plug the values in the equation:

V = \(7^{2}\) × \(\frac{9}{3}\)

V = 49 × 3

V = 147 \(ft^{3}\)

4. Volume of cone = \(\pi r^{2} \frac{h}{3}\)

Variables:

V = volume

r = radius

h = height

V = \(\pi r^{2} \frac{h}{3}\)

r = 8ft /2 = 4 ft (radius is half of the diameter)

h = 10 ft

V =  \(\pi 4^{2} \frac{10}{3}\)

V = \(\pi\) × 16 × \(\frac{10}{3}\)

V = \(\frac{160}{3} \pi\) \(ft^{3}\)

Some properties are rectangle are stated below:

1. rectangle has four right angles

2. rectangles has four sides and equal opposite sides which are parallel to each other.

3.rectangle has two diagonals which are similar in length.

The bigger side lengths are called length and the smaller sides are called breadth of rectangle.

if area of rectangle is given, we can find length when area is divided by its breadth.

 length = area/breadth

hence, length of rectangle is determined from the value of area and breadth.

The equation of the circle into the standard form will be (x + 7)² + (y + 15)² = 1.

It is the close curve of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.

Let r be the radius of the circle and the location of the center of the circle be (h, k). Then the equation of the circle is given as,

(x - h)² + (y - k)² = r²

The area of the circle is 9π. Then the radius of the circle is given as,

\(\bold{\dfrac{11}{2 }}\)

Step-by-step explanation:

Given the geometric series:

\(\{\dfrac{1}2, -1, 2, -4, ..... \}\)

To find:

Sum of series upto 5 terms using the geometric series formula = ?

Solution:

Formula for sum of a n terms of a geometric series is given as:

\(S_n=\dfrac{a(1-r^n)}{1-r} \ \{r<1 \}\)

\(a\) is the first term of the geometric series

\(r\) is the common ratio between each term (2nd term divided by 1st term or 3rd term divided by 2nd term ..... ).

Here:

\(a = \dfrac{1}{2}\)

\(r = \dfrac{-1}{\dfrac{1}{2}} = -2\)

\(n=5\)

So, applying the formula for given values:

\(S_5=\dfrac{\dfrac{1}2(1-(-2)^5)}{1-(-2)} \\\Rightarrow S_5=\dfrac{1-(-32)}{2 \times 3} \\\Rightarrow S_5=\dfrac{1+32}{6} \\\Rightarrow S_5=\dfrac{33}{6} \\\Rightarrow \bold{S_5=\dfrac{11}{2}}\)

So, the answer is

\(\bold{\dfrac{11}{2 }}\)

Answer:  3

Step-by-step explanation:

first substitute 2 into 4, so its 2*4 = 8x

Second, substitute 2 into -3 so itś 2*-3= -6

So, so far we're at 8x-6-8+4+2x, we combine the integers (which is -6 & -8, and we get -14)

So far, we are now at 8x-14=4+2x.

Now we add 14, to cancel out -14.

Then, we add 14 to 4, making 18.

Then, we subtract -2 to cancel out 2x.

Then, we subtract 2x to 8x, Making 6x

Now, final step :)

We divide 6x=18

which is 18 divided by 6

which is 3 :)

44 + 38 can be written in the form a(b + c) as:

44 + 38 = 2(22 + 19) = 2(41)

We may use the distributive property to factor 44 + 38 by first determining their greatest common factor (GCF), which is 2, and then writing the result as follows:

44 + 38 = 2(22) + 2(19)

By removing the second from the equation, we may further reduce it: 44 + 38 = 2(22 + 19).

Therefore, 44 + 38 can be written in the form a(b + c) as:

44 + 38 = 2(22 + 19) = 2(41)

To determine the elasticity, we need to differentiate both sides of the equation with respect to x and then multiply by (x/y):

Differentiating the equation with respect to x:

3.45 * d/dx(log(y)) = 87.6 * d/dx(log(x))

Using the property of logarithmic differentiation, we have:

3.45 * (1/y) * dy/dx = 87.6 * (1/x) * dx/dx

Simplifying and rearranging the equation:

(1/y) * dy/dx = (87.6/3.45) * (1/x)

(1/y) * dy/dx = 25.43/x

Multiplying both sides by (x/y):

dy/dx = (25.43/x) * (x/y)

dy/dx = 25.43/y

The elasticity is given by the ratio of the derivative of y with respect to x to the ratio of y to x. In this case, the elasticity is:

Elasticity = dy/dx * (x/y)

Substituting the value we obtained for dy/dx:

Elasticity = (25.43/y) * (x/y)

Elasticity = 25.43 * (x/y^2)

Therefore, the elasticity is given by 25.43 times the ratio of x to y squared.

Answer:

I'm unable to plot graph, but I can give you the steps to graph the equation y = -²- 10x - 16 on the given set of axes.

Plot the vertex of the parabola: The vertex of the parabola is the point where the parabola changes direction. To find the vertex, you can use the formula (-b/2a, f(-b/2a)), where a, b, and c are the coefficients of the equation y = ax² + bx + c. In this case, a = -1, b = -10, and c = -16, so the vertex is (-10/2(-1), -(-10/2(-1))² - 10(-10/2(-1)) - 16) = (5,16).

Plot the roots: The roots of the equation are the values of x that make y = 0. To find the roots, you can set y = 0 and solve for x. In this case, y = 0 = -x² - 10x - 16. This equation can be solved by factoring or by using the quadratic formula. The roots are x = 4 and x = -2.

Plot five points on the parabola, including the vertex and the roots. To do this, you can substitute different values of x into the equation y = -x² - 10x - 16 and find the corresponding y-values. For example, you could plot the point (4,0), which is one of the roots, and (5,16), which is the vertex.

Connect the points to form a parabola.

b) 18% of the data is to the right: z = 0.915.

The z-score of a measure X of a normally distributed variable that has mean represented by \(\mu\) and standard deviation represented by \(\sigma\) is obtained by the equation presented as follows:
