Compare a number line model for adding whole numbers and a number line model for adding fractions. How are they the same? How are they different

Answer: $5

Step-by-step explanation:

We should note that since there was a 30% off sale, it means that he paid for 70% (100% - 30%) of the sales price.

Therefore, let the price of the socks be represented as x.

70% of x = 14

70/100 × x = 14

0.7 × x = 14

0.7x = 14

x = 14 / 0.7

x = 20

Therefore, the price of the socks was $20. Since there are 4 pairs, each pair will be:

= $20 / 4

= $5

Answer:

[tex]\huge\boxed{\sf Add}[/tex]

Step-by-step explanation:

To get the total number of atoms in a compound, we should add the subscripts to get the total number.

For example:

[tex]\sf C_6H_{12}O_6[/tex] (Glucose)

Add the subscripts of the compound:

=> 6 + 12 + 6 = 24

Hence, Glucose has 24 atoms in its compound.

Answer:

x = 3, y = 30.4

Step-by-step explanation:

From the given diagram;

8x - 3 = 6x+3 (alternate exterior angle are equal)

Collect like terms

8x - 6x = 3 + 3

2x = 6

x = 6/2

x = 3

Also;

8x - 31 + 5y + 35 = 180 (sum of angle on a straight line is 180)

8(3) - 31 + 5y + 35 = 180

5y + 24 - 31 + 35  = 180

5y + 28 = 180

5Y = 180 - 28

5Y = 152

y = 152/5

y = 30.4

Hence x = 3, y = 30.4

9514 1404 393

Answer:

Step-by-step explanation:

A quadratic function y=ax^2 +bx +c is symmetric about the vertical line x=-b/(2a). That is the x-coordinate of the vertex (maximum or minimum).

Here, we have ...

  h = -16t^2 +44t +5

  t = -44/(2(-16)) = 11/8 = 1.375

It takes 1.375 seconds for the ball to reach its maximum height.

The height at that time is ...

  h = (-16(11/8) +44)(11/8) +5 = (-22 +44)(11/8) +5 = 121/4 +5 = 141/4 = 35.25

The maximum height is 35.25 feet.

Answer:

y=36degrees

Step-by-step explanation:

74+2y+34=180

2y+108=180

2y+108-108=180-108

2y=72

72/2

y=36degrees

Answer:

Step-by-step explanation:

Because these are supplementary angles they must have a sum of 180 degrees.

74+2y+34=180

2y+108=180

2y=72

y=36 degrees

Answer:

=(x-7)(x-4)

Explanation:

x^2-11x+28

(x^2-7x)+(-4x+28)

x(x-7)-4(x-7)

=(x-7)(x-4)

Given:

A figure of a triangle.

To find:

The values of x and y.

Solution:

From the given triangle it is clear that the base angles of the triangle are equal, so the triangle is an isosceles triangle.

Altitude on the base of the isosceles triangle from from the opposite angle is a median. It means, it divides the base in two equal parts.

In the given triangle, the altitude divides the base in two equal parts and the measure of each part is 9 units.

In a right triangle,

[tex]\cos \theta=\dfrac{Base}{Hypotenuse}[/tex]

[tex]\cos 60^circ=\dfrac{9}{y}[/tex]

[tex]\dfrac{1}{2}=\dfrac{9}{y}[/tex]

[tex]1\times y=9\times 2[/tex]

[tex]y=18[/tex]

And,

[tex]\tan \theta=\dfrac{Perpendicular}{Base}[/tex]

[tex]\tan 60^\circ=\dfrac{x}{9}[/tex]

[tex]\sqrt{3}=\dfrac{x}{9}[/tex]

[tex]9\sqrt{3}=x[/tex]

Therefore, the correct option is D.

Answer:

D.

Answer:

502.85 feet

Step-by-step explanation:

Given that,

The radius of a Ferris wheel, r = 16 feet

We need to find how far will you travel if you take a ride that goes around 5 times.

Distance = 5×2πr

So,

= 10πr

[tex]=10\times \dfrac{22}{7}\times 16\\\\=502.85\ \text{feet}[/tex]

So, the required distance is 502.85 feet.

Answer:

The original value of the car is $24,000

Step-by-step explanation:

Here, we want to calculate the original value of the car

Let the original value of the car be $x

Now, 4/5 of this value is $19,200

Mathematically, we have it that;

4/5 * x = 19,200

4x = 5 * 19,200

x = (5 * 19,200)/4

x = $24,000

x = 98

The median  score of Ms. Singh's 20 students is 82.5

The mean is the average value which can be calculated by dividing the sum of observations by the number of observations

Mean = Sum of observations/the number of observations

A Median represents the middle value of the given data when arranged in a particular order.

We are given the Students in Ms. Singh's class had the following scores on their last quiz.

First, we have to arrange the given data in an ordered manner. Thus:

55, 68, 72, 73, 75, 77, 78, 79, 82, 82, 83, 85, 85, 85, 86, 86, 87, 91, 92, 95

The median = the average of the 10th and 11th data

Median = (82 + 83) ÷ 2

Median = 165 ÷ 2

Median = 82.5
