The three angles of a triangle have a ratio of 5:7:13. Find the measure of each angle.

Answer:

Step-by-step explanation:

A=LW

L=A/W, given A=15 and W=3.75

L=15/3.75

L=4cm

Answer:

  30√3 m ≈ 52 m

Step-by-step explanation:

The side ratios in a 30°-60°-90° triangle are 1 : √3 : 2. The long leg of the triangle is √3 times 30 m, or about 51.96 m.

The distance between the tree and the tower is about 30√3 m ≈ 52 m.

__

If you haven't memorized the ratios of this special triangle, you can use the relation ...

  Tan = Opposite/Adjacent

  tan(30°) = 30/d

  d = 30/tan(30°) = 30√3 = 51.96 . . . . same as above

Answer:

Students review how to determine the surface area and volume of a rectangular prism, that all dimensions are equal in cubes so the volume of cubes are the length of any side raised to the third power, or cubed. This prepares them for two associated activities. First, students find the volumes and surface areas of rectangular boxes such as cereal boxes and then figure out how to convert their boxes into a new, cubical boxes having the same volume as the original. As they construct the new, cube-shaped boxes from the original box material, students discover that the cubical box has less surface area than the original, and thus, a cube is a more efficient way to package items. Students consider why consumer goods are generally not packaged in cube-shaped boxes, even though this would require fewer materials and ultimately, less waste. Then, to display their findings, each student designs and constructs a mobile that contains a duplicate of his or her original box, the new cube-shaped box of the same volume, the scraps that are left over from the original box, and pertinent calculations of the volumes and surface areas involved.

Step-by-step explanation:

prime #'s between 1 and 45:

2,3,5,7,11,13,17,19,23,27,29,31,37,41,43

P(prime,prime) = 15/45 × 15/45 or 1/3 × 1/3

add the expressions

Answer:

20 yd²

Step-by-step explanation:

lets do the big one

4 x (6-2) = 4 x 4 = 16 yd²

2 x (4-2) = 2x2 = 4 yd²

16 yd² + 4 yd² = 20 yd²

Another way

Find the area of the figure if it was a rectangle

4 x 6 = 24 yd²

then subtract 2 x 2 = 24 yd² - 4 yd² = 20 yd²

Answer:

20

Step-by-step explanation:

Solve the area of the squares separately, then add. the small square has a length and width of 2, and 2x2 is 4, so that area is 4. the bigger one has a length and width of 4, and 4x4 is 16, and then we add the two values together, and 16+4 is 20, so the total area is 20.

Answer:

To receive 1 foot of snow it will take about 18 hours.

Step-by-step explanation:

Given that a city receives 2 inches of snowfall every 3 hours, to write and graph a function that describes the relationship and determine how long does it take to receive 1 foot of snow, the following calculation must be performed:

1 foot = 12 inches

(12/2) x 3 = X

6 x 3 = X

18 = X

Thus, to receive 1 foot of snow it will take about 18 hours.

Answer:

age is 35

Step-by-step explanation:

5a - 20 + (-3a) = 50

2a - 20 = 50

2a = 70

a = 35

Answer:

6

Step-by-step explanation:

use the formula of slopes

[tex] = \frac{y2 - y1}{x2 - x1} \\ = \frac{32 - 8}{1 - ( - 3)} \\ = \frac{24}{4} \\ = 6[/tex]

Answer:

[tex]\frac{31 }{11 }[/tex]

Step-by-step explanation:

The formula to solve this is: [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]. In this case, the expression would be: [tex]\frac{32 -1 }{8 -(-3) }[/tex] or [tex]\frac{32 -1 }{8 +3 }[/tex]. This is also [tex]\frac{31 }{11 }[/tex].

Hope it helps and is correct!

Answer:

Sometimes

Step-by-step explanation:

Example 1:

Take two numbers as [tex]7,8[/tex]

LCM of [tex]7,8=7(8)=56[/tex]

In this case, the lcm of two numbers is equal to the product of the two numbers.

Example 2:

Take two numbers as [tex]6,3[/tex]

[tex]6=3(2)[/tex]

So,

LCM of [tex]6,3=3(2)=6[/tex]

In this case, the lcm of two numbers is not equal to the product of the two numbers.

Therefore,

Sometimes, the lcm of two numbers is equal to the product of the two numbers.

Answer:

The value of X is 11

Step-by-step explanation:

Isolate the variable by dividing each side by the factors that don't contain the cariable.

Answer:

Step-by-step explanation:

Im not for sure.. but I think it would be something like 3,9

Answer:

We rearrange the first equation into y = 8x - 42 and we substitute it in to get

-4x - 6 = 8x - 42 so 12x = 36 so

x = 3 and y = -18

Answer:

Quadratic Trinomial

Step-by-step explanation:

Hello there!

quadratic trinomial equations look like -  [tex]x^2+bx+c[/tex]

given formula [tex]n^2-7n+21[/tex] which is in the form of a quadratic trinomial

a quadratic trinomial consist of a constant, a  variable to the power of 2,  and a variable

Reasons why its not the other answer choices:

Linear equations do not have variables with powers therefore we can eliminate answer choice linear trinomial and linear polynomial

[tex]n^2-7n+21[/tex] is not a quadratic polynomial because a quadratic polynomial consists of a = 0

This is what a quadratic polynomial looks like

[tex]ax^2+bx+c=0[/tex]

so we can conclude that [tex]x^2+bx+c[/tex] is an example of a quadratic trinomial
