How do you find the properties of a 30 60 90 triangle?.

The equation of the line if the y-intercept i (0,6) and the lope i 15 is:

B. y = 15x 6

The equation of the line is given in slope-intercept form (y = mx + b) where m is the slope and b is the y-intercept. The y-intercept is the point where the line crosses the y-axis and is given as (0,6). Therefore, the value of b is 6. The slope is given as 15. Therefore, the equation of the line is y = 15x + 6. This equation means that for every unit increase in x, y increases by 15 units and the line passes through the point (0,6)

This method is applicable for other equations as well, as long as they are in slope-intercept form (y = mx + b). The slope-intercept form is a way to represent a linear equation where the slope and the y-intercept are known. If the equation is not in that form, it can be rearranged to make it so. Once the equation is in slope-intercept form, you can identify the slope and the y-intercept which can be useful in understanding the characteristics of the line such as its direction and position in the coordinate plane.

Answer:

x = 10

Step-by-step explanation:

Based on the given conditions, formulate: 140 - 12 X x = 20

Rearrange unknown terms to the left side of the equation: -12x = 20 - 140

Calculate the sum or difference: -12x = -120

Divide both sides of the equation by the coefficient of variable: x = -120/-12

Determine the sign for multiplication or division: x = 120/12

Cross out the common factor: x = 10

get the result: x = 10

Answer: x = 10

What is the rectangular prism?

A rectangular prism is a three-dimensional geometric shape with six rectangular faces. It is also known as a rectangular cuboid, or simply a cuboid. It has three dimensions: length, width, and height. It can be represented by the formula: V = lwh where l is the length, w is the width, and h is the height.

We can use the formula for the volume of a rectangular prism to solve this problem. The formula is:

V = l * w * h

where V is the volume, l is the length, w is the width, and h is the height. We know that the volume of the box is 35 cubic inches and that the length and width are 2 inches each. So we can substitute those values into the formula and solve for h:

35 = 2 * 2 * h

To find h, we'll divide both sides of the equation by 4.

h = 35/4 = 8.75

Hence, the height of the popcorn box is 8.75 inches.

The partial sum is called  the sum of part of the sequence, they are also called as finite series.

Since adding all the terms does not yield the sums of these series, we can study their behaviour by looking for patterns in the partial sums. A partial sum is the total of a limited number of the series' terms. To see how the infinite sum behaves, we can examine a collection of these sums. The index of the final term in the sum is used to denote each of these partial sums. For instance, is the total of an infinite series' first six terms.

The first five partial sums are in the following order: 1, 4, 9, 16, and 25. This trend will persist, and the terms will keep expanding without limit. In other words, because the infinite total is infinitely huge, the partial sums keep increasing.

Let one angle to be 'x', other angle to be 'y' and the number to be 'c'.

So, according to the question:

one angle is forty more than four times a number and the other angle is

To make a 360mL mixture that contains 9% vinegar, use 288 mL of the first brand and 72 mL of the second brand.

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to compute a percentage of a number, we should divide it by its whole and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the term percent signifies. The letter "%" stands for it.

Given, A chef is going to use a mixture of two brands of Italian dressing. The first brand contains 8% vinegar, and the second brand contains 13% vinegar. The chef wants to make 360 milliliters of a dressing that is 9% vinegar.

to set up an equation that will match the word problem. Let's call the amount of the first brand, F, and the amount of the second brand, S.

We want the total mixture to be 360mL so: F + S = 360

Also, you want the total mixture to contain 8% vinegar so:

.08F + .13S = .09(360)

Now, we can solve the system of equations using substitution.

F + S = 360

.08F + .13S = .09(360)

F = 360 - S      [solve 1st equation for F]

.08(360 - S) + .13S = .09(360)    [substitute into 2nd equation]

28.8 -0.08s+0.13s = 32.4

0.05s = 3.6

S = 72

F + 72 = 360     [substitute answer for S back into original equation]

F = 288

Among them, the four most Chinese ones are the famous "Cowhand and Weaver Girl", "Meng Jiangnu", "Liang Shanbo and Zhu Yingtai" and "The Legend of the White Snake". The most widespread, the most influential.

Brief introduction: the gigolo knit legend began in the book of songs, cable ":" Qi he vega ", "Huan he cow". "Nineteen Ancient Poems · Long Distance Star" has called the cowherd and weaver girl husband and wife. Ying Shao "custom" Yi wen: "Zhinv Tanabata when crossing the river, make magpie bridge, legend has it that the magpie head without reason all Kun, because beam (note: bridge) to cross Zhinv also. The story has been preliminarily formed and combined with the Qixi Festival custom.

The legend of Meng Jiangnu originated from the record of Qi Liang's wife refusing to hang herself in the area of the Marquis of Qi and adhering to the rules of etiquette in the Zhuan. Later, it was added in the Dangong that "Duke Zhuang of Qi attacked Ju and took away (tunnel) and Qi Liang died. The weeping wife who greeted his coffin on the road is the archetype of the story. Han Liu Xiang's Biography of Liannu (IV) : "Qi Liangzhu died in battle, his wife cried in the city, ten days the city collapsed." And Tang (anonymous) "carved jade collection" record "Qin when Yan Qi Liang, married Meng Chao female Zhongzi wife, because good was built the Great Wall officials killed, Zhongzi cry under the Great Wall, the city collapsed. It is known that this legend was popular in the Tang Dynasty, but Meng Zhongzi and Qiliang were renamed Meng Jiangnv and Fan Xiliang in the legend. The story of Butterfly lovers first appeared in Tang's "Ten Taoist and Four Tibetan Records", which recorded the story of Liang and Zhu "having a taste of schoolmates" and "sharing the tomb". There are more detailed records in Xuanbaozhi of late Tang Zhang Reading. To the Ming Dynasty Feng Menglong's "Ancient and modern novels", and added to the British Taiwan confused belt, Liang Shanbo doubts and butterflies.

The story of White Snake came into being the latest. The origin of the story is as follows. It originates from the Three Towers of West Lake. To the Ming Dynasty Feng Menglong's "Lady White Forever Town Leifeng Pagoda" (" Warning Word "), the story has been preliminarily finalized.

Answer: 7.5 cm; 1.6 cm

Step-by-step explanation:

If that is a right triangle, it is probably a 30 60 90 triangle and we can use this special property to say that the leg facing the 30 degree angle is half of the hypotenuse. The hypotenuse measures 15 cm, which means we can say that the leg facing the 30 degree angle is 7.5 cm. Next, since 21 cm is the sum of the 2 legs, we can add 21 cm to 15 cm to get 36 cm. Now that we know our hypotenuse, perimeter, and one of our legs, we can find the other leg by using basic algebra to get 1.6 cm. Hopefully this helps! I'm not sure tho.
