Answer:

15 miles/hour = 0.25 miles/minute

The cyclist would have traveled 5 miles in 20 minutes.

Step-by-step explanation:

15 miles per hour is written as

15 miles/hour

To convert 15 miles/hour to miles/minute

From 1 hour = 60 minutes

∴ 15 miles/hour = 15 miles/ 60 minutes

= (15/60) miles/minute

= 0.25 miles/minute

To calculate how many miles the cyclist will travel in 20 minutes

That is, Time, t = 20 minutes

Velocity, v = 15 miles/hour = 0.25 miles/minute

Distance, s = ??

From,

[tex]Velocity = \frac{Distance}{Time}\\[/tex]

∴[tex]Distance = Velocity[/tex] × [tex]Time[/tex]

[tex]Distance = 0.25 miles/minute[/tex] × [tex]20 minutes[/tex]

[tex]Distance = 5 miles[/tex]

Hence, The cyclist would have traveled 5 miles in 20 minutes.

Answer:

$91

Step-by-step explanation:

f(x) = 2.5 x

$25 more would + $25 to the function

60% = .6

Revenue is f(x) = 2.5x  which we have to multiply by the .6

g(x) = $25 + .6 (2.5 x)

If we have 44 watermelons then we plug in 44 for x

x = 44

g(x) = $25 + .6 (2.5*44)

g(x) = $25 + .6 (110)

g(x) = 25 + 66

g(x) = $91

The profit is $91

Answer:

[tex]x=-7[/tex]

Step-by-step explanation:

So we have the equation:

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

To solve, subtract 5 from both sides. This is the subtraction property of equality:

[tex](x+5)-5=(-2)-5[/tex]

The left side cancels:

[tex]x=(-2)-5[/tex]

Subtract on the right.

[tex]x=-7[/tex]

So, our answer is -7.

Answer: x=16

Step-by-step explanation:

[tex]2x+6=3x-10[/tex]

Subtract 6 on both sides

[tex]2x+6-6=3x-10-6[/tex]

[tex]2x=3x-16[/tex]

Subtract 3x on both sides

[tex]2x-3x=3x-16-3x[/tex]

[tex]-x=-16[/tex]

Divide -1 on both sides

[tex]\frac{-x}{-1}=\frac{-16}{-1}[/tex]

[tex]x=16[/tex]

Answer:

50mph

Step-by-step explanation:

Given the following :

Distance (d) of journey = 20 miles

Wind speed = 30mph head wind in one way, 30mph tail wind in the other direction

Return trip = 45 minutes (45/60 = 0.75 hour) less Than the outbound journey

Speed of plane in still air

Outbound trip :

Velocity = Distance / time

Time = distance / velocity

Velocity = (v - 30) due to head wind

Return Velocity (V +30) due to tail wind

Outbound time = return distance

20 / (v - 30) = 20 / (v +30) + 0.75

20v + 600 = 20v + 0.75v^2 + 22.5v - 600-22.5v-675

600 = 0.75v^2 - 1275

0.75v^2 = 1875

v^2 = 1875/ 0.75

v^2 = 2500

v = sqrt(2500)

v = 50mph

Answer:

11r^2+10pr-9p i think

Step-by-step explanation:

On simplifying the expression we get 11r²+10pr-9p

In Algebra, the like terms are defined as the terms that contain the same variable which is raised to the same power. In algebraic like terms, only the numerical coefficients can vary. We can combine the like terms to simplify the algebraic expressions.

Given here, -r²+8pr-p-(-12r²-2pr+9p) = -r²+12r²+8pr+2pr-10p

                                                            =11r²+10pr-9p

Hence, On simplifying the expression we get 11r²+10pr-9p

Answer:

4.5

Step-by-step explanation:

Let the number be x, then:

The number is 4.5

Answer:

4.5

Step-by-step explanation:

let the number be x , then

10x + 15 = 60 ( subtract 15 from both sides )

10x = 45 ( divide both sides by 10 )

x = 4.5

The number is 4.5

x = 6 and KL = 32

First off, you're not brainless, your brain needs practice that's all.

Since L is the midpoint of the line KM, that means KL = LM

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

LM [tex]= 9x - 22[/tex]

KL = LM

[tex]5x+2=9x-22\\5x=9x-24\\-4x=-24\\x=\frac{-24}{-4} \\x=6[/tex]

KL [tex]= 5x + 2[/tex], substitute [tex]x[/tex]:

KL [tex]=5(6)+2[/tex]

KL [tex]= 30 + 2[/tex]

KL [tex]= 32[/tex]

let's also find LM just for fun

LM [tex]= 9x-22[/tex], substitute [tex]x[/tex] again:

LM [tex]= 9(6) -22[/tex]

LM [tex]=54-22[/tex]

LM [tex]=32[/tex]

this proves that KL = LM

Answer:

Total area of the composite figure = 129.1 square units

Step-by-step explanation:

Area of the figure attached = Area of semicircle + Area of the rectangle

Since area of the semicircle = [tex]\frac{1}{2}\pi r^{2}[/tex]

where 'r' = radius of the circle

Area of the semicircle = [tex]\frac{1}{2}\pi (4)^{2}[/tex]

                                     = 8π

                                     = 25.1 square units

Area of the rectangle = Length × width

                                    = 13 × 8

                                    = 104 square units

Total area of the composite figure = 25.1 + 104

                                                         = 129.1 square units

[tex]x\leq 0[/tex]

Step-by-step explanation:

The domain is the span of x-values covered by the graph.

From the graph, we can see that the x-values covered by the graph is all values to the left of zero including zero.

Therefore, the domain is all x-values less than or equal to 0:

[tex]x\leq 0[/tex]

Further notes:

In interval notation, this is:

Answer:

There are five ways in which the squirrels can get all 24 acorns.

Step-by-step explanation:

The information provided is:

Each squirrel makes at least one trip.

Consider the table for the total number of trips the squirrels make get all 24 acorns:

Brown (2)       Gray (3)       Black (5)               Total no. of acorns

    1                     4                  2               (1 × 2) + (4 × 3) + (2 × 5) = 24    

    2                     5                  1               (2 × 2) + (5 × 3) + (1 × 5) = 24    

    3                     1                  3               (3 × 2) + (1 × 3) + (3 × 5) = 24    

    4                     2                  2               (4 × 2) + (2 × 3) + (2 × 5) = 24    

    5                     3                  1               (5 × 2) + (3 × 3) + (1 × 5) = 24    

Thus, there are five ways in which the squirrels can get all 24 acorns.

Answer:

Ok, let's define the notation:

A is the number of 2-point field goals that your team scored.

B is the number of 3-point field goals that your team scored:

We know that:

" your team scored three times as many 2-point field goals than it did 3-point field goals,"

This can be written as:

A = 3*B

" And scored a total of 90 points."

A*2 + B*3 = 90

Then we have a system of two equations and two variables:

A = 3*B

A*2 + B*3 = 90

Now we can replace the first equation into the second one and get:

(3*B)*2 + B*3 = 90

B*6 + B*3 = 90

B*9 = 90

B = 90/9 = 10

And we know that:

A = 3*B

A = 3*10 = 30

Then your team scored 30 2-point field goals and 10 3-point field goals (a total of 40 if you combine them)

Hey there! I'm happy to help!

We want to get c all by itself on one side of the equation. Usually variables go on the left side, so let's flip the equation around.

c/9=-8

If we multiply c/9 by 9, the 9 will cancel out because if you divide by 9 and then multiply by 9 it just equals 1. We can do this to isolate the c, but whatever you do to one side of the equation, you have to do to the other. So, we multiply both sides by 9.

c/9×9=-8×9

c=-72

Have a wonderful day! :D

c = -72

Answer:

6

Step-by-step explanation:

Let the two integers be a and b.

The difference of them is 26. Thus:

[tex]a-b=26[/tex]

One of them (let's use a) is 2 more than 5 times the other. Thus:

[tex]a=2+5b[/tex]

Substitute:

[tex]a-b=26\\(2+5b)-b=26[/tex]

Combine like terms:

[tex]4b+2=26[/tex]

Subtract 2 from both sides:

[tex]4b=24[/tex]

Divide by 4:

[tex]b=6[/tex]

And the second number is:

[tex]a-b=26\\a-6=26[/tex]

Add 6 to both sides:

[tex]a=32[/tex]

So, our two numbers are 32 and 6

And the smaller integer is 6.

And we're done :)

Answer:

The smaller intrger is:

6

Step-by-step explanation:

a = 5b + 2

a - b = 26

then:

(5b+2) - b = 26

4b = 26 - 2

4b = 24

b  = 24/4

b = 6

a = 5b + 2

a = 5*6 + 2

a = 30 + 2

a = 32

Check:

32-6 = 16

32 = 5*6 + 2

32 = 30 + 2

6<32

the smaller integer is:

6

Answer:

160

Step-by-step explanation:

240/3= 80

80*2= 160

Answer: NO

Step-by-step explanation:

14 × 10^8 is not in scientific notation

scientific notation: a×10^b, where should be 0<a<10

As seen above, 14 is greater than 0, but also greater than 10, thus, it is not in scientific notation.

------------------

EXTRA: How to change it into proper scientific notation

To change it into scientific notation, we need to divide 14 by 10, do get 1.4. (or just move the decimal point to the left by 1 unit)

1.4 is within the range of 0-10.

1.4 × 10^9 (remember, we just divided 14 by 10, and so we need to add on the exponent by 1)

Answer:

2/3

Step-by-step explanation:

h = height of the cone

Vcone = πr²h/3

H = h/2 = height of the cylinder

Vcylinder = πr²H = πr²h/2

Vcone/Vcylinder = (πr²h/3)/(πr²h/2)

= πr²h/3 x 2/πr²h

= 2/3

Answer:

2/3

Step-by-step explanation:

h = height of the cone

Vcone = πr²h/3

H = h/2 = height of the cylinder

Vcylinder = πr²H = πr²h/2

Vcone/Vcylinder = (πr²h/3)/(πr²h/2)

= πr²h/3 x 2/πr²h

= 2/3
