Your class started at 12:12PM and ended at 12:50PM. What angle did the minute hand of a watch sweep through during the class?

 A. 132

 B. 228

 C. 153

 D. 168

​

$40 will be taken off the bill and you will be paying a total of $120.

Multiply 160 by .25 to find the amount taken off ($40), and then subtract from the total to find the amount that you will be paying ($120).

Have a great day!

Answer:

You will pay $120

Step-by-step explanation:

There are many methods in solving this percentage equation, but this is by far my favorite. Here is how it works.

1.Take 160, the original amount.         160

2.Then take the percent amount        .25

and convert into decimal.           ---------------------

3. Multiply the numbers                   40.00

4. Subtract the product from         160

original amount, 160.                  -    40

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

                                             $120

That is how I would get my answer. I am very sorry if the formatting messes up, but it is this basic problem:     160*.25=40.00 then 160-40=120

Answer:

46 pieces

Step-by-step explanation:

We get n (number of pieces) as follows

n = (4.6 $) / (0.1 $/piece) = 46 pieces

Answer:

Yung bought 46 pieces of bubble gum for $4.6

Explanation:

We are given that each piece of gum cost $0.1 and that he spent $4.6 on gums

To get the number of gums he bought, we will simply use cross multiplication as follows:

1 piece .........................> 0.1

x pieces ......................> 4.6

Therefore:

[tex]x = \frac{4.6*1}{0.1}= 46[/tex] pieces of gum

The range is the y-values.

Let r = range

r = {0, -3, -9, 5, 7}

X measures 30°, Y measures 67°, and Z measures 83°.

Since the sum of the measures of the angles of a triangle is 180, and the sum of the measures of the second and third angles is five times the measure of the first angle, and the third angle is 16 more than the second, for find the measures of the three angles, the following calculation must be performed, posing linear equations:

Therefore, X measures 30 °, Y measures 67 °, and Z measures 83 °.

Let x, y, and z represent the measures of the first, second, and third angles of the triangle. We can create a system of equations to find the values of x, y, and z. Solving this system, we find that x = 28, y = 32, and z = 48.

Let's use x, y, and z to represent the measures of the first, second, and third angles, respectively.

The sum of the measures of the second and third angles is five times the measure of the first angle, so we have the equation y + z = 5x.

The third angle is 16 more than the second, so z = y + 16.

Since the sum of the measures of the angles of a triangle is 180, we have the equation x + y + z = 180.

Now we can solve these equations to find the measures of the three angles.

Substituting z = y + 16 into the equation y + z = 5x, we get y + y + 16 = 5x, which simplifies to 2y + 16 = 5x.

Substituting z = y + 16 into the equation x + y + z = 180, we get x + y + y + 16 = 180, which simplifies to x + 2y + 16 = 180.

Now we have a system of equations:

2y + 16 = 5x

x + 2y + 16 = 180

Solving this system, we find that x = 28, y = 32, and z = 48.

Answer:

The quantity sold by Annette was $600

The quantity sold by Barb was $480

The quantity sold by Carlita was $400

Step-by-step explanation:

Let

x ----> quantity sold by Annette

y ---> quantity sold by Barb

z ---> quantity sold by Carlita

we know that

[tex]x+y+z=1,480[/tex] ----> equation A

[tex]x=y+120[/tex] ----> equation B

[tex]y+z=x+280[/tex] ----> equation C

substitute equation C in equation A and solve for x

[tex]x+(x+280)=1,480[/tex]

[tex]2x=1,480-280[/tex]

[tex]2x=1,200[/tex]

[tex]x=\$600[/tex]

Find the value of y

[tex]x=y+120[/tex]

[tex]600=y+120[/tex]

[tex]y=600-120=\$480[/tex]

Find the value of z

[tex]x+y+z=1,480[/tex]

[tex]600+480+z=1,480[/tex]

[tex]1,080+z=1,480[/tex]

[tex]z=\$400[/tex]

therefore

The quantity sold by Annette was $600

The quantity sold by Barb was $480

The quantity sold by Carlita was $400

The solution involves setting up a system of three linear equations based on the given problem. By solving these equations methodically, we find that Barb, Annette, and Carlita sold $400, $520, and $560 of clothing respectively.

The problem involves setting up and solving a system of linear equations. Here's how we approach it:

So, Barb sold $400 of clothing, Carlita sold $560, and Annette sold $520.

Answer:

a = 15

Step-by-step explanation:

Given

3a + b = 54 ← substitute b = 9

3a + 9 = 54 ( subtract 9 from both sides )

3a = 45 ( divide both sides by 3 )

a = 15

An equation is formed when two equal expressions. The value of a in the equation 3a+b=54, when b equals 9 is 15.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

The given statement "3 a plus b equals 54" in terms of the equation can be written as,

3a + b = 54

Given an equation 3a+b=54. Also, the value of b in the given equation is 9. Therefore, the value of a in the given equation can be written as,

3a + 9 = 54

Subtract 9 from both sides of the equation,

3a + 9 - 9 = 54 - 9

3a = 45

Divide both the sides of the equation by a,

3a/3 = 45/3

a = 15

Hence,  the value of a in the equation 3a+b=54, when b equals 9 is 15.

Answer:

x > -99/4

Step-by-step explanation:

I must assume that you meant (-2/5)x -9<9/10.

This inequality has 3 terms.  The LCD is 10.  Multiply each term by 10 and reduce the result:

10(-2/5)x - 10(9) < 10(9/10), or:

-4x - 90 < 9

Adding 90 to both sides results in:

-4x < 99

Here we must divide by a negative number (that is, by -4).  This requires reversing the direction of the inequality sign:

x > -99/4 is the final solution.

Turtle is closest to the sea level.

In which horizontal straight line, we represent integer numbers from low value to high, from left to right, is called number line.

Zero is in the middle of that line.

If we consider the number line, then in the left side of zero, we have all the negative values, where .... < -5< -4< -3< -2< -1< 0

And in the right side of zero, we have all the positive values, where 0<1<2<3<4<5 and so on....

We know that, Level zero is called the sea level.

So, if we assume number line in vertical way, then the zero will be the sea level.

Here, if we arrange levels of animals from low to high, we get,

Sea lion(-10)<Shark(-7)<Turtle(-6)<0 <Seagull(+24)

We see that, zero is in between -6 & 24

The distance between 0 & -6 is 6 units whereas between 0 & 24 is 24 units.

Step-by-step explanation:

Unread pages = (a) 1 - 12; (b) 32 - 46; (c) odd numbered pages from 48 - 200

The number of pages in each range is:

(a)  n₁ = 12 - 1 + 1  = 12

(b) n₂ = 46 - 32 + 1 = 15

(c) n₃ = 200 - 48 + 1 =153

Half the pages are odd-numbered.

153/2 = 76½.

200 and 48 are both even so there are more even-numbered pages in the range.

There are 77 even-numbered and 76 odd-numbered pages.

Answer:

$189

Step-by-step explanation:

Let their total amount of spending money be x

given that $135 they spent is 5/7 of their total spending money,

mathematically:

135 = (5/7) x     (multiply both sides by 7)

135 (7) = 5x

945 = 5x

5x = 945  (divide both sides by 5)

x = 945 / 5

x = 189

Shannon and Kelly originally had $189 as their spending money.

Let x be the original amount of spending money.

According to the problem, Shannon and Kelly spent $135 on gift certificates, which is 5/7 of the total spending money.

This can be represented by the equation: 5/7 * x = $135.

To solve for x, we can multiply both sides of the equation by 7/5 to get x = $135 * 7/5 = $189.

Therefore, Shannon and Kelly originally had $189 as their spending money.

Answer:700000

Step-by-step explanation:

The number of zeros for hundred thousand is five .Thus100,000

So you start by counting the zeros from the right hand side of the figure 672000 to the left till your counting reach 5.

So wen you get to the fifth zero check the number that it falls on . Thus 7 will be that number,And since it's greater than 5 you add 1 to the prefix of the 7 which is 6 to be become 6+1=7 , hence the answer is 700000 to the nearest hundred thousand.

Answer:

700 000

Step-by-step explanation:

    6               7              2           7              2           6

now round the number to nearest hundred thousand.

hundred thousand digit in 672726 is 7

If rounding number is greater than equal to 5 then next number increase by 1.

If rounding number is less than 5 then next number does not change.

here rounding number is 7 > 5

So, next digit 6 change to 7

Rounded number  = 700 000

672 726   → 700 000
