Answer 8 divide by 10 =0.8

0.8x 25=20

Step-by-step explanation: i hope this helps

The equation for the total cost, c, in terms of the number of songs, s, purchased is c = 1.25s and  $25 can purchase 20 songs.

Two or more expressions with an Equal sign is called as Equation.

Let x be the price of each song.

The cost to purchase 8 songs is given as $10, so we can write the equation:

8x = 10

To find the equation for the relationship between the total cost, c, and the number of songs, s, purchased, we can solve for x:

8x = 10

x = 10/8

x = 1.25

So the price of each song is $1.25, and the equation for the total cost, c, in terms of the number of songs, s, purchased is:

c = 1.25s

To find how many songs can be purchased for $25, we can use the equation:

c = 1.25s

Substitute c = $25, and solve for s:

25 = 1.25s

s = 25/1.25

s = 20

Therefore, at this rate, $25 can purchase 20 songs.

Hence, the equation for the total cost, c, in terms of the number of songs, s, purchased is c = 1.25s and  $25 can purchase 20 songs.

Step-by-step explanation:

The volume of the clay sphere the artist started with is 113.04 in^3

We know that the artist starts with a sphere of clay with a radius of 3 inches, and we want to find the volume of clay that he has.

Then we just need to find the volume of the sphere.

Remember that for a sphere of radius R, the volume is:

[tex]V = (4/3)*3.14*R^3[/tex]

In this case, R = 3 in, replacing that we get.

[tex]V = (4/3)*3.14*(3 in)^3 = 113.04 in^3[/tex]

The volume of the clay sphere the artist started with is 113.04 in^3

Answer:

10

Step-by-step explanation:

Given two points we can use the distance formula to calculate the distance between the two points.

Formula:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Where the x and y values are derived from the given points.

we are given the points (1,7) and (9,1)

To find the distance we plug in the x and y values of the points into the formula

[tex]d=\sqrt{(9-1)^2+(1-7)^2} \\9-1=8\\1-7=-6\\d=\sqrt{8^2+(-6)^2} \\8^2=64\\-6^2=36\\d=\sqrt{64+36} \\64+36=100\\\sqrt{100} =10\\d=10[/tex]

So we can conclude that the distance between the points (1,7) and (9,1) is 10 units

Answer:

The distance between the buildings is:

D = 413.3 ft

Step-by-step explanation:

Ok, here we have two triangle rectangles, such that these triangle rectangles share a common vertex which is Dale.

One of the triangles, let's call it triangle A, has the catheti:

Distance between Dale and Building A = d1

Height of Building A = 464 ft

The other triangle (triangle B) has the catheti:

Distance between Dale and Building B = d2

Height of building B = 321ft

We want to find the distance between the buildings, which is equal to d1 + d2.

Then we want to find d1 and d2.

For triangle A:

We know that the angle at the vertex where Dale is standing, is 75°

Then the adjacent cathetus is d1, and the opposite cathetus is the height of building A.

Remember that:

Tan(θ) = (opposite cathetus)/(adjacent cathetus)

Then:

Tan(75°) = (464 ft)/(d1)

d1 = (464 ft)/(Tan(75°)) = 124.3 ft

Now for triangle B, the angle at the vertex where Dale is standing is 48°.

from this vertex, we have d2 as the adjacent cathetus and the height of build B as the opposite cathetus.

Then:

Tan(48°) = 321ft/d2

d2 = (321ft)/(Tan(48°)) = 289ft

Then the distance between the buildings is:

D = d1 + d2 =  124.3 ft +  289ft = 413.3 ft

Answer:

  -10

Step-by-step explanation:

The first step is to write what you mean. We think you mean (-1000)^(1/3).

If you've been paying attention to place-value, and/or cubes of small integers, you already know that 10^3 = 1000. Since we're concerned with an odd power, we also know ...

  -1000 = (-10)^3

Then your expression is ...

  (-1000)^(1/3) = ((-10)^3)^(1/3) = (-10)^(3/3) = (-10)^1 = -10

__

Some calculators can evaluate this for you (see attached).

Some calculators and spreadsheets use logarithms to compute roots or fractional powers, so will give you an error when you try to compute this. You should know that an odd-index root of a negative number (here, 3rd root of -1000) has the same sign as the number: negative. Then you can use your calculator to compute the positive root and add the sign yourself:

  (-1000)^(1/3) = -(1000^(1/3)) = -(10) = -10

_____

Of course, a 1/3 power is the same as a cube root. Your calculator may have a cube root button that works just fine with negative numbers.

Answer:

(i) 22.5

(ii) 7.2

Step-by-step explanation:

(i)

AB:PQ = 2:5 = 1:2.5

So PQ is 2.5 times longer than AB.

PQ=2.5AB=(2.5)9=22.5

(ii):

Since the triangles are similar, their sides are in ratio to each other. So if PQ was 2.5 times longer than AB, QR must also be 2.5 times longer than BC:

QR=2.5BC

BC=QR/2.5=18/2.5=7.2

Answer:

35

Step-by-step explanation:

The first number that appears in both sequences is 35.

Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.

Now, The first sequence starts with 20 and adds 5 each time, so the first few terms are:

20, 25, 30, 35, 40, 45, 50, 55, 60, ...

And, The second sequence starts with 56 and subtracts 7 each time, so the first few terms are:

56, 49, 42, 35, 28, 21, 14, 7, 0, ...

Hence, Looking at these lists, we can see that the first number that appears in both sequences is 35.

This is the fifth term in the first sequence as,

⇒ 20 + 5 + 5 + 5 + 5 = 35

And, the fourth term in the second sequence is,

⇒ 56 - 7 - 7 - 7 - 7 = 35

Hence, the first number that appears in both sequences is 35.
