Map has a scale 1 cm: 40 mi. What is the distance between two towns that are 3.3 cm apart on the map?

Given:

Chang ran three times last week. The distances he ran (in kilometers) are 4, 8.36, 18.9.

To find:

The total distance Chang ran on these three days.

Solution:

It is given that the distances he ran (in kilometers) are 4, 8.36, 18.9.

We need to add these three distances to get the total distance Chang ran on these three days.

[tex]4+8.36+18.9=31.26[/tex]

Therefore, the total distance Chang ran on these three days is 31.26 kilometers.

Answer:

50°

Step-by-step explanation:

In a parallelogram, opposite angles are equal and all angles sum up to 360°.

So, 2x + 2x + x + 30 + x + 30 = 360

6x + 60 = 360

6x = 300

x = 50°

I think this is the answer.

Answer:

There are 150 blue marbles in Alex's bag.

Step-by-step explanation:

Let [tex]x[/tex], [tex]y[/tex], [tex]z[/tex] be the quantities of red, blue and yellow marbles, respectively. From statement we derive three rational equations for initial and final ratios:

Initial ratio

[tex]\frac{x}{y} = \frac{6}{10}[/tex] (1)

[tex]\frac{y}{z} = \frac{10}{15}[/tex] (2)

Final ratio

[tex]\frac{x + 10}{z - 25} = \frac{1}{2}[/tex] (3)

After some algebraic handling we get the following system of linear equations:

[tex]x - \frac{3}{5}\cdot y = 0[/tex] (1)

[tex]y - \frac{2}{3}\cdot z = 0[/tex] (2)

[tex]2\cdot (x + 10) = z - 25[/tex]

[tex]2\cdot x +20 = z - 25[/tex]

[tex]2\cdot x - z = -45[/tex] (3)

The solution of the system of linear equations is:

[tex]x = 90[/tex], [tex]y = 150[/tex], [tex]z = 225[/tex]

Answer:

Leading coefficient is the coefficient of the highest power of x.

[tex]x^5[/tex] is the highest power.

Therefore, leading coefficient = [tex]\frac{1}{4}[/tex]

Option D

Answer:1/4

Step-by-step explanation:

Answer:

Yes, it is.

Step-by-step explanation:

When you plug in 2 for y, and 2 for x. you get:

2 ≤ 4(2) - 6

2 ≤ 8 - 6

2 ≤ 2

2 is equal to 2, so it is correct.

Answer:

b = 4[tex]\sqrt{3}[/tex] , c = 8

Step-by-step explanation:

Using the sine ratio in the right triangle and the exact value

sin30° = [tex]\frac{1}{2}[/tex] , then

sin30° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{4}{c}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )

c = 8

Using Pythagoras' identity in the right triangle

b² + 4² = 8²

b² + 16 = 64 ( subtract 16 from both sides )

b² = 48 ( take the square root of both sides )

b = [tex]\sqrt{48}[/tex] = [tex]\sqrt{16(3)}[/tex] = 4[tex]\sqrt{3}[/tex]

Answer:

OK THIS IS A BIGGY....c = 8

Step-by-step explanation:

First, find b.

using the pythagorean theorem, a² + b² = c²

to find b using an angle, do b = √(c² - a²)

then, b = a * tan(β)

(β is the angle 30°)

So, b = 6.928

Then, plug it into the pythagorean theorem

4² + 6.928² = c²

16 + 47.997184 = c²

63.997184 = c²

√63.997184 = √c

c = 7.99982399806

Rounded is 8 :)

It is because there are more in the box, there is also a high probability of him choosing an orange next but it will not be a pattern. Sorry if I’m wrong :(

Answer:

B: 8

Step-by-step explanation:

The area of the two smaller squares equals the area of the big square so find the area to the big square

17 * 17 = 289

289 - 225 = 64

The square root of 64 is 8 so the answer is 8.

Answer:

17/12 or 1 5/12

Step-by-step explanation:

You need to make the denominators the same, the common denominator is 12. In the end, they become 9/12 and 8/12. ad those to you get 17/12 or 1 5/12. Was this helpful?

Answer:

=17/12

Step-by-step explanation:

Get a common denominator between the two fractions.

Common denominator will be 12

Multiple 2/3 by 4 (top and bottom) to get 8/12

Multiply 3/4 by 3 (top and bottom) to get  9/12

Add the numerators of both fractions (8+9=17)

final fraction is 17/12 (denominator stays the same)

Answer:

3/11 = 12/44. 1/4 = 11/ 44 so 3/11 > 11/44

Answer and Step-by-step explanation:

A common denominator that both numbers has is 44.

To get that number for both numbers, multiply [tex]\frac{3}{11} by \frac{4}{4}[/tex] and [tex]\frac{1}{4} by \frac{11}{11}[/tex].

[tex]\frac{3}{11}[/tex] ×  [tex]\frac{4}{4}[/tex] = [tex]\frac{12}{44}[/tex]

[tex]\frac{1}{4}[/tex] × [tex]\frac{11}{11}[/tex] = [tex]\frac{11}{44}[/tex]

[tex]\frac{12}{44} > \frac{11}{44} \\\\\frac{3}{11} > \frac{1}{4}[/tex]

The number of edges is 9. The correct option is B.

A vertex is a point in geometry where two or more curves, lines, or edges come together. Vertices are frequently represented by the letters P, Q, R, or S. As a result of this definition, vertices are the intersection of two lines that create an angle as well as the corners of polygons and polyhedra.

The given figure is in two parts. The bottom is a rectangular prism and the top is a pyramid with a square base.

The number of the edges will be calculated as below:-

Total edges = Number of the edges of Pyramid  + Number of the edges of the prism

Total edges = (5 - 4)  + 8

Total edges = 9

Therefore, the number of edges is 9. The correct option is B.

Answer:

103

Step-by-step explanation:

We know supplementary angles equal 180 degrees. So the problem will be:  180 - 77 = 103

Answer:

103 degrees

Step-by-step explanation:

Supplementary angles add up to 180 degrees.  Thus, the supplement of 77 degrees is (180 - 77) degrees, or 103 degrees.
