The diagram below is divided into equal parts. Which fraction of the parts is white?

Answer:

4/15

Step-by-step explanation:

Answer:

For this case, the first thing we must do is define variables:

x: number of hammers

y: number of wrenches

We write the system of inequations:

10x + 6y <= 120

x + y> = 14

Step-by-step explanation:

Answer:

16x2=32

Step-by-step explanation:

A multiple of 16 is any number divisible by 16. Multiplying 16 by 2 creates a number divisible by 16 and 2, meaning it is divisible by 16.

16x2=32 32/16=2

Answer:

$36.41/week

Step-by-step explanation:

Divide 750 miles/wk by 28 MPG -> = 26.79 gallons/week (I rounded.)

Divide 750 miles/wk by 20 MPG -> = 37.50 gallons/week

Car -> 26.79 gallons x $3.40 = $91.09

SUV -> 37.50 gallons x $3.40 = $127.50

$127.50 - $91.09 = Difference of $36.41/week

The difference in the total weekly cost of gasoline is $36.43 if you drive an average of 750 miles per week.

Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

It is given that:

You drive an average of 750 miles per week in a car that gets 28 miles per gallon. With gasoline prices at $3.40 per gallon.

For the first car:

Total number of miles = 750 miles

The gasoline prices at $3.40 per gallon

The car that gets 28 miles per gallon

Number of gallons used = 750/28 = 26.785

The total price of the gallon used = 26.785x3.40 = $91.07

For the SUV car:

Total number of miles = 750 miles

The gasoline prices at $3.40 per gallon

The car that gets 20 miles per gallon

Number of gallons used = 750/20 = 37.5

The total price of the gallon used = 37.5x3.40 =  $127.5

The difference in total weekly cost of gasoline = 127.5 - 91.07 = $36.43

Thus, the difference in the total weekly cost of gasoline is $36.43 if you drive an average of 750 miles per week.

Answer:

answer is d

Step-by-step explanation:

Answer:

Option C

Step-by-step explanation:

=> 4p + 2 = 8

Subtracting 2 to both sides

=> 4p = 8-2

=> 4p = 6

Dividing both sides by 4

=> p = 1.5

Answer:

The answer is C.

Step-by-step explanation:

First, you have to subtract 2 to both sides :

[tex]4p + 2 = 8[/tex]

[tex]4p + 2 - 2 = 8 - 2[/tex]

[tex]4p = 6[/tex]

Next, you have to divide it by 4 :

[tex]4p = 6[/tex]

[tex]p = 6 \div 4[/tex]

[tex]p = 3 \div 2[/tex]

[tex]p = 1.5[/tex]

Answer: Is known as a "heart" shape.

Step-by-step explanation:

r = 1 + sin(θ)

Let's do it without a graph, let's use only math and logic:

remember that θ is measured from the x-axis

when θ = 0, we have r = 1 (so we have a radius of 1 over the x-axis)

when θ = pi/2, we have r = 1 + sin(pi/2) = 2

when θ = pi, we have r = 1 + sin(pi) = 1

when θ = 3*pi/2, we have r = 1 + sin(3*pi/2) = 0

First, we have symetry around the y-axis,

now, notice that the value of x in θ = 0, θ = pi and θ = 3*pi/2 is the same. so this is not a circle, this is actually a circle where the bottom part is flatted.

But not actually flat, because between θ = pi and θ = 2pi we are in the negative y-axis, so in this region we have two small bumps that connect in the point (0, 0)

This is a kinda "heart" shape.

Answer: cardioid

Step-by-step explanation:

Answer:

530.66 cm²

Step-by-step explanation:

Area of a circle is 3.14 × radius²

3.14 × 13²

3.14 × 169

=530.66

The area of the circle is 530.66 cm².

Answer:

The answer is (approximately) [tex]530.66 cm^2[/tex]

Step-by-step explanation:

We are given the radius ([tex]13cm[/tex]).

Use the formula for the area of a circle: [tex]\pi r^2[/tex] (using [tex]3.14[/tex] for [tex]\pi[/tex])

Thus...

[tex](3.14)(13)^2[/tex]

We equals around 530.66.

Answer:

[tex]12 \sqrt{2} [/tex]

Step-by-step explanation:

Taking the terms one at a time,

[tex] \frac{14}{ \sqrt{2} } \\ \frac{14 * \sqrt{2} }{ \sqrt{2} * \sqrt{2} } \\ \frac{14 \sqrt{2} }{2} \\ 7 \sqrt{2} [/tex]

[tex] \sqrt{50} \\ \sqrt{25 * 2} \\ \sqrt{25}* \sqrt{2} \\ 5 * \sqrt{2} \\ 5 \sqrt{2} [/tex]

Adding the terms, you have;

[tex]7 \sqrt{2} + 5 \sqrt{2} =(7 + 5) \sqrt{2} = 12 \sqrt{2} [/tex]

Answer:

5668.3

Step-by-step explanation:

The problem can be represented as a right angled triangle as shown below.

The angle of depression is equivalent to the angle inside the triangle (alternate angles) and it is 34°.

The altitude of the balloon is 2999 feet. (opposite)

Using trigonometric function, SOHCAHTOA, we can solve this:

[tex]sin(34) = \frac{opposite}{hypotenuse}\\ \\sin(34) = \frac{altitude}{distance}\\\\sin(34) = \frac{2999}{distance}\\\\distance = \frac{2999}{sin34}\\\\distance = 5668.3 feet[/tex]

The pilot is 5668.3 feet far away from the house.

Answer:

[tex]m=27[/tex]

Step-by-step explanation:

When something is directly proportional, it means that: [tex]a=kb[/tex], where [tex]k[/tex] is some constant (number).

We are given that [tex]m[/tex] is directly proportional to [tex]n^2[/tex], and [tex]m=75[/tex] when [tex]n=5[/tex].

So, we have...

[tex]a=kb[/tex]

[tex]m=kn^2[/tex]

[tex]75=k(5)^2[/tex]

[tex]75=25k[/tex]

[tex]k=3[/tex]

So the full equation is:

[tex]m=3n^2[/tex]

Now, to find the answer when [tex]n=3[/tex], simply put 3 into the equation.

Which gives:

[tex]m=3(3)^2[/tex]                     [tex]m=9(3)[/tex]             [tex]m=27[/tex]

Final answer: m=27.

Answer:

8/17

Step-by-step explanation:

Here, we should know that the sine of an angle is the ratio of the opposite to the hypotenuse

So in this case, 15 is the opposite and 17 is the hypotenuse

To find the cos of same angle, it is the ratio of the adjacent to the hypotenuse

We need the adjacent side

We can use Pythagoras’ theorem here

It states that the square of the hypotenuse equals sum of the squares of the two other sides

let’s say the adjacent is f

17^2 = 15^2 + f^2

f^2 = 17^2 -15^2

f^2 = 64

f = √(64)

f = 8

So the Cos C would be adjacent/hypotenuse = 8/17

Answer:

The single transformation that maps a onto c is the reflection of the triangle a  about the line y = -x

Step-by-step explanation:

To answer the question, we note that the result of reflection of a point (x, y) across the x axis is given as follows;

Coordinates before reflection = (x, y), Coordinates after reflection = (x, -y)

Also, when we rotate a  point, (x, y), 90° clockwise, we have;

Image point before 90° clockwise rotation = (x, y), Image point after 90° clockwise rotation = (y, -x)

Therefore, the rotation of the point (x, -y), 90° clockwise will give

Image point before 90° clockwise rotation = (x, -y), Image point after 90° clockwise rotation = (-y, -x)

Which gives the combined transformation as (x, y) → (-y, -x) which is the rule equivalent to reflection about the line y = -x.

Answer: 1324.12 sq. cm.

Step-by-step explanation:

A=2πrh+2πr2

A = 2π x 8.2 x 17.5 + 2π x 8.2^2

A = 2π x 143.50 + 2π x 67.24

A= 1324.12

Answer:

SA = 1324.1 cm²

Step-by-step explanation:

Surface Area of Cylinder = [tex]2\pi rh+2\pi r^2[/tex]

Where r = 8.2 cm, h = 17.5 cm

=> SA = [tex]2(3.14)(8.2)(17.5)+2(3.14)(8.2)^2[/tex]

=> SA = [tex]901.6+2(3.14)(67.24)[/tex]

=> SA = 901.6 + 422.5

=> SA = 1324.1 cm²

Answer: $150

Step-by-step explanation:

Hi, the question says:

Calculate the simple interest produced by $4500 at 5% simple annual interest in 8 months.

To answer this question we have to apply the simple interest formula:  

I = p x r x t  

Where:  

I = interest  

P = Principal Amount  

r = Interest Rate (decimal form)  

t = years  

Since 1 year = 12 months;  

For 8 months:

8/12 = 2/3 years  

Replacing with the values given  

I = 4500 x (5/100) x 2/3

I = $150

Answer:

f(0) = 3

Step-by-step explanation:

Step 1: Distribute

f(x) = -3x + 3

Step 2: Plug in

f(0) = -3(0) + 3

f(0) = 3

Answer:

f(0) = 3

Step-by-step explanation:

f(x) = -3(x-1)

Put x as 0 and solve.

f(0) = -3(0-1)

Solve the brackets.

f(0) = -3(-1)

Multiply both terms.

f(0) = 3

Answer:

87th term is 497

Step-by-step explanation:

first, you have to find the nth term:

figure out the difference between your set of numbers (in our case +6)

that means that is 6n. next, the nth term is basically the 0th term so you have to find the 0th term. all you have to do is do the inverse of 6n (-6n or -6), which gives us -25.

nth term= 6n-25

now replace n with 87.

final step:

87*6 (6n and n=87) and that gives you 522. then, you have to do 522-25, due to the equation. 522-25=497

497 is your 87th term.

Answer:

Step-by-step explanation:

[tex]a = -19\\d = T_{2} -T_{1} \\d = -19-(-13)\\d = -19+13\\d = -6\\T_{n}= a+(n-1)d \\\\T_{87} = -19+(87-1)-6\\T_{87} = -19+(86)*-6\\T_{87} = -19-516\\T_{87} = -535[/tex]
