Find x+y+z from the following figure​

Mathematics
1 answer:
hoa [83]3 years ago
8 0

Step-by-step explanation:

the inner top vertex angle seems to be 90°, so x = 90° too. all angles around a single point in one side of a line are in total 180°.

also, remember, all angles inside a triangle always sum up to 180°.

so, the third inner angle of the triangle is

180 - 90 - 40 = 50°.

that makes z = 180 - 50 = 130°

and y = 180 - 40 = 140°.

Rectangle prism with length 20inches, width 18inches and height 10inches. Suppose water is pumped out of the aquarium at a rate
Anettt [7]

Answer:

10 minutes

Step-by-step explanation:

To solve this , we need to first calculate the volume of the rectangular prism. Let’s say this is V.

Mathematically, V = w h l where w, h and l are width , height and length respectively.

V = 20 * 18 * 10 = 3600 in^3

Now to get the number of minutes, we divide the volume by the draining rate.

That would be 3600/360 = 10 minutes

Please Hurry) What is the length of side AC of the triangle? □ units. ​
NARA [144]

▪▪▪▪▪▪▪▪▪▪▪▪▪  {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪

\boxed{\mathrm{AC = 25 \:\: units ~}}

\large \boxed{ \mathfrak{Step\:\: By\:\:Step\:\:Explanation}}

As we can see in the given figure, Angles A and B are equal. therefore their opposite sides will be equal to one another, that is ~

  • AB = BC

now, let's plug the values of AB and BC in terms of x and equate them to find the value of x ~

  • 5x + 5 = 7x - 1

  • 7x - 5x  = 5 + 1

  • 2x = 6

  • x = 6 \div 2

  • x = 3 \:  \: units

now , let's find the measure of side AC ~

  • AC = 6x + 7

that is ~

  • 6(3) + 7

  • 18 + 7

  • 25 \:  \: units

Determine the level of measurement of the variable below. Nation of origin Choose the correct answer below. A. Interval B. Ratio
Tanzania [10]

Answer:

Option C) Nominal                                          

Step-by-step explanation:

We are given the following in the question:

Variable:

Nation of origin

Nominal and ordinal:

  • Categorical variables can further be divided as nominal and ordinal.
  • Nominal variable are simple name variable and no numeric value is used to express such variable.
  • Ordinal variable are the variable where position plays an important role but again numerical value is not used to express them.

Ratio and interval:

  • Numerical data can be divided as ratio and interval.
  • Ratio is the data that have true zero value.
  • For interval, absolute zero have no meaning.

Thus, the given variable that is name of origin is a categorical variable.

It is a nominal variable as position plays no role in this.

Thus, the correct answer is

Option C) Nominal
