Answer:

your correct answer is

e no by sss axiom

X= 130°

Step-by-step explanation:

From E, draw EF || AB || CD.

Now, EF || CD and CE is the transversal.

So; <DCE + <CEF = 180° [co. int. <s]

x° + <CEF = 180°

<CEF = (180° – x°).

Again, EF || AB and AE is the transversal.

So; <BAE + <AEF = 180° 01 [co. int. <s ]

105° + <AEC+ <CEF = 180°

105° +25° + (180° – x°) = 180°

x° = 130°

Hello :D

The pen is 9 2/5 rupees and the pencil is 3 1/5 rupees. To work this out we need to subtract them from each other.

9 2/5 - 3 1/5 = 6 1/5 rupees.

The pen cost more by 6 1/5 rupees.

I hope this helps and I would appreciate it, if you could give me brainliest

Answer:

7

Step-by-step explanation:

Lets use Pemdas for this

Parenthesis

Exponents

Multiplication

Division

Addition

Subtraction

First you always do parenthesis, (47+4^2)

Then Exponents 4^2 this means 4x4 and 4x4=16

So (47+16)= 63

so we have 63/3^2

We go to exponents before division according to pemdas

3^2=3x3=9

63/9

63/9=7

Answer:

Step-by-step explanation:

A has 6 elements therefore

a) A has [tex] 2^6[/tex] subsets, and

b) A has [tex]2^{6}-1[tex] proper subsets since we dont want the subset to be equal to A itself.

Answer:

m < Angle one = 45°

Step-by-step explanation:

Angle one = (2x + 5)

135 + 2x + 5 = 180 (because angle is a straight line)

140 + 2x = 180

(140 - 140) + 2x = 180 - 140

2x = 40

2x/2 = 40/2

x = 20

2x + 5

2(20) + 5

40 + 5

45°

Answer:

add all the angles and equal with 180°

Answer:

110

Step-by-step explanation:

5^3-3x5

=125-15

=110

x = 5 and y = 5

y³ - 3x = 5³ - 3 · 5 = 125 - 15 = 110

Answer:

25/32

Step-by-step explanation:

First you want to simplify the fractions. So, 20/32 would be 5/8, and 25/20 would be 5/4. Next, you want to multiply both the numerator and denominator. So, 5x5 is 25 for the numerator, and 8x4 is 32 for the denominator, leaving you with 25/32 for the answer.

Answer:

[tex] \frac{25}{32} x[/tex]

Step-by-step explanation:

[tex] \frac{20}{32} x \times \frac{25}{20} [/tex]

[tex] \frac{1}{32} x \times 25[/tex]

[tex] \frac{25}{32} x[/tex]

Answer:

13,236 minor earthquakes occurred

Step-by-step explanation:

[tex]\frac{Part}{Total}[/tex]

"x" part amount of earthquakes

14,905 total amount of earthquakes

88.8 % part percentage of earthquakes

100% total percentage of earthquakes

[tex]\frac{x}{14905}[/tex] = [tex]\frac{88.8}{100}[/tex]

x = 14,905 × [tex]\frac{88.8}{100}[/tex]

x = 14,905 × 0.888 = 13,235.64 ≈ 13,236 minor earthquakes occurred

Answer:

Step-by-step explanation:

[tex](\frac{3}{7} )^{2} * (\frac{3}{7})^{2}[/tex]

according to the laws of indices in multiplication case if the base are same then their power can be added. So,

[tex](\frac{3}{7} )^{2+1}[/tex]

[tex](\frac{3}{7} )^{3}[/tex]

[tex]\frac{3^{3} }{7^{3} }[/tex]

[tex]\frac{27}{343}[/tex]

Step-by-step explanation: The easiest way to do this and the way I commonly use is to subtract 17 from 89then make it negative as you are making the negative number smaller by adding a smaller number therefore your answer is -72

Answer: [tex]f^{-1}(x)=2x-6[/tex]

Step-by-step explanation:

To find the inverse, we want to switch the y with x and x with y. Once we do that, we solve for y.

[tex]y=\frac{1}{2}x+3[/tex]        [switch x and y]

[tex]x=\frac{1}{2}y+3[/tex]        [subtract both sides by 3]

[tex]x-3=\frac{1}{2} y[/tex]        [multiply both sides by 2]

[tex]y=2x-6[/tex]

Now, we know that  [tex]f^{-1}(x)=2x-6[/tex].

Answer:

100

Step-by-step explanation:

we first find the area of the rectangle:

8*10=80

now we find the area of the triangle:

(6*8)/2=24

Now we add the area of the triangle and the rectangle up:

24+80=104

Now we round that up to the nearest ten:

100

Answer: b = -6

Step-by-step explanation:

-233 = 6(3+7b) +1

-233 = 18 + 42b +1

-233 - 18 - 1 = 42b

-252 = 42b

-252/42 = b

b = -6
