Answer:

7 days

Step-by-step explanation:

Five men do 200 yards in one day

One man does 200/5 = 40 yards in 1 day.

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

Now you want to know something about 8 men

8 men can do 40 * 8 = 320 yards in 1 day

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

2240 yards / 320 yards = 7 days

Answer:

There are 925 in half of a year

There are 1321 in 2 years

There are 8838 in 10 years

Step-by-step explanation:

* Lets revise the exponential function

- The original exponential formula was y = ab^x, where a is the initial

 amount and b is the growth factor

- The new growth and decay functions is y = a(1 ± r)^x. , the b value

 (growth factor) has been replaced either by (1 + r) or by (1 - r).

- The growth rate r is determined as b = 1 + r

* Lets solve the problem

∵ The number of fish is growth every month

∴ We will use the growth equation y = a(1 + r)^x, where a is the initial

  amount of the fish, r is the rate of growth every month and x is the

  number of months

- There are 821 of a type of fish

∴ The initial amount is 821 fish

∴ a = 821

- Their growth rate is 2% each month

∴ The rate of growth is 2% per month

∴ r = 2/100 = 0.02

- We want to find how many of them be in half year

∵ There are 6 months in half year

∴ y = 821(1 + 0.02)^6

∴ y = 821(1.02)^6 = 924.58 ≅ 925

* There are 925 in half of a year

∵ There are 24 months in 2 years

∴ y = 821(1 + 0.02)^24

∴ y = 821(1.02)^24 = 1320.53 ≅ 1321

* There are 1321 in 2 years

∵ There are 120 months in 10 years

∴ y = 821(1 + 0.02)^120

∴ y = 821(1.02)^120 = 8838.20 ≅ 8838

* There are 8838 in 10 years

Answer:

The correct option is C

Step-by-step explanation:

We have given the roots -6, 1 and 4.

Write down the roots:

x= -6 , x=1 , x=4

Rewrite the roots as an expression:

Now Multiply the terms:

=(x²-x+6x-6)(x-4)

=(x²+5x-6)(x-4)

=x(x²+5x-6) -4(x²+5x-6)

=x³+5x²-6x-4x²-20x+24

Step-by-step explanation:

Answer:

12 km

Step-by-step explanation:

So the situation is:

8 km/h for X hours

6 km/h for y hours

X * 8 + y * 6 = 26.4

and X + Y = 3.9 hours

Since 234/60 = 3.9 hours

You could write that X = 3.9 - Y

(3.9-Y) * 8 + y * 6 = 26.4

31.2 -8Y +6Y = 26.4

-2Y = -4.8

Y = 2.4 hours

X = 3.9-2.4 = 1.5 hours

So 1.5 * 8 = 12 km

Answer:

AB = 12km

Step-by-step explanation:

From the question we can get the following information,

The whole trip is 26.4 km and 3.9 hours ([tex]\frac{234}{60}[/tex]), and we can form the following two equations.

[tex]x + y = 3.9[/tex]   and [tex](x*8km/h) + (y*6km/h) = 26.4km[/tex]

Where X is distance between A and B, and Y is distance between B and C. We can solve the first equation for X and plug X into the second equation.

[tex]x = 3.9 - y[/tex]  ........   and we can plug it into the the second equation and solve for y

[tex]((3.9-y)*8)+(6y) = 26.4[/tex]

[tex](31.2-8y)+6y = 26.4[/tex]

[tex]31.2-2y = 26.4[/tex]

[tex]-2y = -4.8[/tex]

[tex]y = 2.4[/tex]

Now we can plug in y to the first equation to solve for x

[tex]x = 3.9-2.4[/tex]

[tex]x = 1.5[/tex]

Finally, we can multiplay 8km/h by 1.5 hours to find the distance from A to B

[tex]AB = 8km/h * 1.5h[/tex]

[tex]AB = 12km[/tex]

Answer:

The sides are equal to

x=6.9 ft and y=39.4 ft

Step-by-step explanation:

step 1

Find the adjacent side to the angle of 80 degrees

Let

x ----> the adjacent side to the angle of 80 degrees

we know that

The function cosine of angle of 80 degrees is equal to divide the adjacent side to the angle of 80 degrees by the hypotenuse (40 ft)

cos(80°)=x/40

x=(40)cos(80°)

x=6.9 ft

step 2

Find the opposite side to the angle of 80 degrees

Let

y ----> the opposite side to the angle of 80 degrees

we know that

The function sine of angle of 80 degrees is equal to divide the opposite side to the angle of 80 degrees by the hypotenuse (40 ft)

sin(80°)=y/40

y=(40)sin(80°)

y=39.4 ft

Answer:

A.  square pyramid

Step-by-step explanation:

A square pyramid has a triangular cross section when the cross section is taken perpendicular to the base.

The solid that has a triangular cross section when the cross section is taken perpendicular to the base is a square pyramid. A cross section through the sloping triangular faces of the square pyramid will reveal a triangular shape.

To answer this, consider the properties of each option:

A square pyramid has a square base and triangular faces that meet at a common point above the base, resembling a series of tetrahedra joined together. When a cross section is taken perpendicular to its square base, it would indeed reveal a triangle shape as it would pass through these sloping triangular faces.

A cube would not result in a triangular cross section since it has all square faces.

A hexagonal prism has a hexagon as its base, and taking a cross section perpendicular to this base would yield a hexagon, not a triangle.

Similarly, a rectangular prism would result in a rectangle or square from such a cross section.

Therefore, the correct answer is a square pyramid.

Answer:

4/15.

Step-by-step explanation:

In probability, there are two types of events: the ones that are not related to each other and the ones that are related to each other. The former types of events are called independent events. In such cases, since the occurrence of one event is not related to and does not affect the other event, therefore, the probabilities of both events can be multiplied if they occur together. It is given that:

P(Q) = 7/15.

P(R) = 4/7.

P(Q and R) = P(Q)*P(R) = 7/15 * 4/7 = 4/15.

Therefore, the probability is 4/15!!!

Answer:

7 inches

Step-by-step explanation:

The dimension of the rectangular gift is 10 by 12 inches so let us find the perimeter of this rectangle.

Perimeter of rectangular gift = 2 (L+ W) = 2 (10 +12) = 44 inches

Since we are to use the same length of ribbon to wrap a circular clock so the perimeter or circumference should be 44 inches.

[tex]2\pi r=44[/tex]

[tex]r=\frac{44}{2\pi }[/tex]

[tex]r=7.003[/tex]

Therefore, the maximum radius of the circular clock would be 7 inches.

Answer:

The maximum radius of the circular clock is 7 in

Step-by-step explanation:

We must calculate the perimeter of the rectangle

We know that the rectangle is 10 in x 12 in

If we call L the rectangle length and we call W the width of the rectangle then the perimeter P is:

[tex]P = 2L + 2W[/tex]

Where

[tex]L = 10[/tex]

[tex]W = 12[/tex]

[tex]P = 2 * 10 + 2 * 12\\\\P = 20 + 24[/tex]

[tex]P = 44\ in[/tex]

Now we know that the perimeter of a circle is:

[tex]P = 2\pi r[/tex]

In order for the perimeter of the circumference to be equal to that of the rectangle, it must be fulfilled that:

[tex]2\pi r = 44\\\\r=\frac{44}{2\pi}\\\\r=7\ in[/tex]

We solve the equation for r

Replace n in the equation with each given value and solve for m.

You are given n = {-2, 1, 4}

When n = -2:

3m = -2-7

3m = -9

m = -9/3

m = -3

When n = 1:

3m = 1-7

3m = -6

m = -6 /3

m=-2

When n = 4:

3m = 4-7

3m = -3

m = -3/3

m = -1

m = {-3, -2, -1}

Answer:

d (last choice)

Step-by-step explanation:

The explicit form of a geometric sequence is [tex]a_n=a_1 \cdot r^{n-1}[/tex] where [tex]a_1[/tex] is the first term while [tex]r[/tex] is the common ratio.

We are given the first term [tex]a_1=47[/tex].

We are given the sixth term [tex]a_6=-789929[/tex].

If we divide 6th term by 1st term this is the result:

[tex]\frac{a_1 \cdot r^5}{a_1 }=\frac{-789929}{47}[/tex]

Simplify both sides:

[tex]r^5=-16807[/tex]

Take the fifth root of both sides:

[tex]r=-7[/tex]

The common ratio is -7.

So all we have to do is start with the first term and keep multiplying by -7 to get the other terms.

[tex]a_1=47[/tex]

[tex]a_2=47(-7)=-329[/tex]

[tex]a_3=47(-7)^2=2303[/tex]

[tex]a_4=47(-7)^3=-16121[/tex]

[tex]a_5=47(-7)^4=112847[/tex]

[tex]a_6=47(-7)^5=-789929[/tex]

The terms -329,2303,-16121,112847 are what we are looking for in our choices.

That's the last choice.

Answer:

[tex]4x^2+20x+25[/tex] square units

Step-by-step explanation:

We are given that side of a square has the dimension [tex]s = 2x + 5[/tex] and using this, we are to write an expression for the area of this square.

We know that the formula of area of a square is given by:

Area of square = [tex]s^2[/tex]

So substituting the given value in the above formula to get:

Area of square = [tex](2x+5)^2 = (2x+5)(2x+5) = 2x(2x)+2x\times5+5(2x)+5\times5 = 4x^2+20x+25[/tex] square units

Answer:

[tex]A = 4x ^ 2 + 20x +25[/tex]

Step-by-step explanation:

Remember that all sides of a square have the same length. Therefore, the Area of a square is defined as:

[tex]A = s ^ 2[/tex]

Where s is the length of the sides of the squares.

In this case we know that the length of the sides is:

[tex]s = 2x + 5[/tex]

So the area is:

[tex]A = (2x +5) ^ 2[/tex]

We develop the expression and we have left that the area is:

[tex]A = 4x ^ 2 + 20x +25[/tex]

Answer: [tex]36z^2+12z-21[/tex]

In order to simplify the given the expression:

 [tex](11z^2+4z-6)+(4z-7+12z^2)+(-8+13z^2+4z)[/tex]

You must distribute signs:

[tex]=11z^2+4z-6+4z-7+12z^2-8+13z^2+4z[/tex]

And finally, you must add the like terms:

[tex]=36z^2+12z-21[/tex]

Answer:

y = 4x - 2.

Step-by-step explanation:

The slope is  difference in y values  / difference in x values

= (6 - -10) /  (2 - -2)

= 16 / 4

= 4.

Using the point-slope form of a line

y - y1 = m(x - x1)  where m = slope and (x1, y1) is a point on the line, we have:

y - 6 = 4(x - 2)

y = 4x - 8 + 6

y = 4x - 2.
