Answer:

No

Step-by-step explanation:

In order to form a right triangle, you would need one of the angles to be 90 degrees. Plus all the angles don't equal 180 degrees (the angles of a triangle should add up to 180)

Answer:

-5

Step-by-step explanation:

Answer:

-5

Step-by-step explanation:

The result is positive, so you know the number must be negative. What two numbers normally make 60? That would be 5 and 12, but since the 12 is negative (-12), that means the 5 must be negative (-5). So, the answer is -5.

Given:

The figure of two triangle XYZ and UWV.

To find:

The theorem that is used to verify [tex]\Delta XYZ\sim \Delta UWV[/tex].

Solution:

In triangle XYZ,

[tex]m\angle X+m\angle Y+m\angle Z=180^\circ[/tex]        (Angle sum property)

[tex]70^\circ+90^\circ+m\angle Z=180^\circ[/tex]

[tex]160^\circ+m\angle Z=180^\circ[/tex]

[tex]m\angle Z=180^\circ-160^\circ[/tex]

[tex]m\angle Z=20^\circ[/tex]

In triangle XYZ and triangle UWV,

[tex]m\angle Y\cong m\angle W[/tex]                  (Right angles)

[tex]m\angle Z\cong m\angle V[/tex]                  (Equal measures)

Two angles of one triangle are congruent to corresponding angles of another triangle. So, the triangles are similar by AA property of similarity.

[tex]\Delta XYZ\sim \Delta UWV[/tex]           (AA similarity theorem)

Therefore, the correct option is B.

Answer:

tens of thousand vs hundred

Step-by-step explanation:

Given:

The faces on a number cube are labeled 1,2,2,3,4, and 5.

The number cube is rolled 114 times.

To find:

How many times would you expect the number 2 to appear?

Solution:

We have,

Total outcomes = 1,2,2,3,4, and 5.

Number of total outcomes = 6

Favorable outcomes = 2 and 2

Number of favorable outcomes = 2

The probability of getting 2 is:

[tex]P(2)=\dfrac{\text{Number of favorable outcomes}}{\text{Number of total outcomes}}[/tex]

[tex]P(2)=\dfrac{2}{6}[/tex]

[tex]P(2)=\dfrac{1}{3}[/tex]

Now, the expected number of times when 2 to appear is:

[tex]E(x)=114\times P(2)[/tex]

[tex]E(x)=114\times \dfrac{1}{3}[/tex]

[tex]E(x)=38[/tex]

Therefore, the expected number of times is 38.

5.23 =d

Step-by-step explanation:

cost = fee + daily charge*days

520 = 180+ 65d

Subtract 180

520 -180 = 180+65f-180

340 = 65d

Divide by 65

340/65 = 65d/65

5.23 =d

Answer:

64º and 116º

Step-by-step explanation:

x  + (x - 52) = 1080

2x - 52 = 180

2x = 232

x = 116º

x - 52 = 64º

Answer:

Step-by-step explanation:

It is C because members in the set C can be found in the universal set (U)

Step-by-step explanation:

it's a right angled triangle

it's also a scalene triangle because not all sides are equal

Solve for q

-----------------

[tex](8q-5)^o+81=180^o[/tex]

[tex]8q-5+81=180[/tex]

Choice C is incorrect because it is missing the [tex]2ab[/tex]. Hope this helped!

Answer:

In 2020 the population will be 6,233.

Step-by-step explanation:

Giving the following information:

Present value (PV)= 5,600

Growth rate (g)= 1.8%

Number of periods= 6 years

To calculate the population in 2020, we need to use the following formula:

FV= PV*(1 + g)^n

FV= 5,600*(1.018^6)

FV= 6,232.67 = 6,233

In 2020 the population will be 6,233.

Answer:

CD = 400. CD = − C (100) + D (500) = 400. 1 = I 5 = V 10 = X 100 = C 500 = D 1,000 = M.

Answer:

La longitud de [tex]x[/tex] es [tex]5\sqrt{2}[/tex] unidades.

Step-by-step explanation:

La figura es un cuadrado atravesado por una diagonal, significando que existen dos triángulos rectángulos, cuyos ángulos interiores son 45°, 45° y 90°, respectivamente. Por Geometría Euclideana, tenemos que la longitud de la hipotenusa es igual a [tex]\sqrt{2}[/tex] veces la longitud de cualquiera de sus catetos:

[tex]x = \frac{10}{\sqrt{2}}[/tex]

[tex]x = 5\sqrt{2}[/tex]

La longitud de [tex]x[/tex] es [tex]5\sqrt{2}[/tex] unidades.

Answer:

(B) M - J = 6

Step-by-step explanation:

Here we have the variables:

M = number of games that Mike won.

J = number of games that Jeanie won.

And we know that there is a total of 38 games played, then if a game can not end in a draw, we have the equation:

M + J = 38

Now we want to find the other equation needed to solve this problem:

We also know that Mike won 6 more games than Jeanie, this is written as:

M = J + 6

We can subtract J in both sides to get:

M - J = 6

This is the equation from option B, so we can conclude that the correct option is B.

Answer:

9

Step-by-step explanation:

A = B + 2

C = B - 3

A x C = 66

A = Andrew

C = Chris

B = Beatrice

Multiply A and c together

(B + 2) x (b - 3)

b^2 - 3b + 2b - 6

b^2 -b - 6 = 66

b^2 - b - 72 = 0

factors of -72b^2 that add up to - b are -9b + 8b

b^2 + 8b -9b - 72

b (b + 8) -9(b + 8)

b = 9 or - 8

b = 9

I believe it's A, C and D.

Answer and explanation:

The standard error is used to measure the difference between the sample mean and the population mean. It uses standard deviation to measure the level of deviation of the sample mean from the population mean. In other words, the accuracy of the sample mean by way of representing the mean of the population is measured using the standard error. If there is significant difference then standard error is bigger usually non-zero while it is less significant with smaller standard error.

Answer:

4

Step-by-step explanation:

7x = x² - 8

=> x² - 7x - 8 = 0

use quadratic formula:

a = 1, b = -7, c = -8

x = [tex]\frac{-(1)±\sqrt{(-7)^{2} - 4(1)(-8) } }{2(1)}[/tex] (pls ignore the "A" I don't know why it's showing up)

=> x = [tex]\frac{-1±\sqrt{49 + 32} }{2}[/tex]

=> x = [tex]\frac{-1±9 }{2}[/tex]

=> x = [tex]\frac{-1 +9}{2}[/tex] = 4 or [tex]\frac{-1-9}{2}[/tex] = -5 (the answer is only 4 since it's asking for the positive solution)

Answer:

-6x^2-288

Step-by-step explanation:

18x - 432 - 18x - 6x² +144

Combine like terms

-6x^2+18x-18x-432+144

-6x^2-288

The volume, of the cement used to make the sidewalk is 8 ft³

Volume is defined as the space occupied within the boundaries of an object in three-dimensional space. It is also known as the capacity of the object.

Given that, James is using cement to make a new sidewalk and new steps,

He will make a new rectangular sidewalk that is 8 feet long, 4 feet wide, and 0.25 foot thick.

Volume = length x width x height

Volume = 8 x 4 x 0.25 = 8 ft³

Hence, the volume, of the cement used to make the sidewalk is 8 ft³

Answer:

3 5/12

Step-by-step explanation:

Answer:

41/12 gallons

= 3 5/12 gallons

Step-by-step explanation:

Since it can hold 8 1/4 gallons and currently has 4 5/6 gallons, you subtract.

You need to get the common denominator to subtract cleanly so we can turn the fractions into improper fractions.

8 1/4 = 33/4 because 8 is equal to 8 full 4/4ths so multiply 8 by 4 and add 1 for the remaining 1/4.

Then 4 5/6 becomes 29/6 with the same concept earlier.

So we can change the denominator to 12 on both fractions (33/4 and 29/6) so we can subtract.

33/4 becomes 99/12 because they are still equivalent, it's just that you multiplied the top and bottom by the same number.

29/6 becomes 58/12 because we multiplied the fraction by 2/2.

Those two new fractions stated previously are the same as the original because we multiplied them by 1/1, because 3/3 and 2/2 is still equal to 1/1, and the new fractions can be simplified down to the original.

Since we have 99/12 and 58/12, we can subtract cleanly into

99 - 58 = 41

So the answer is 41/12
