In which of the expressions below will x = 25? Select all that apply.

Answer:

Z = 2

Step-by-step explanation:

This tape diagram is split into two equal parts.

Since 2 and 2 are equal, and since 2 and 2 have a sum of 4, then z is equal to 2.

Answer:

z = 2

Step-by-step explanation:

if two z go into 4 then it's 2 because 2 is the only number that goes into 4 twice

Answer:

13.999975443466645809607317476264924904625964880398

Step-by-step explanation:

That's only 50 digits

Answer:

Solution:- In the given figure

Side of square= 10 cm

area of square =  side x side m= 10 x 10 = 100 sq cm

Now , diameter of semi circle AOD = 2r = 10cm

⇒ radius of  semi circle AOD = 5 cm

∴ area of AOD =  

similarly Area of semicircle BOC =  

Area of white portion in figure 1 = area of square - [ area of semicircle BOD + area of semicircle AOD]

=

Total area of white portion in the given figure=

∴Area of Shaded portion = area of square - area of total white portion

=  

So the area of shaded portion is  

Now perimeter of AD(which is a semicircle) = (as perimeter of semicircle=πr)

So the perimeter of shaded region = 4×perimeter of AD=4×15.7=62.8cm

Answer:

The best known approximations to π dating to before the Common Era were accurate to two decimal places; this was improved upon in Chinese mathematics in particular by the mid-first millennium, to an accuracy of seven decimal places.

Answer:20

Step-by-step explanation: 17+24+26+13=80

Divide by how many numbers there are. Answer: 20

Answer:

20

Step-by-step explanation:

Mean = Sum divided by the number of terms

(17+24+26+13)/4

(80)/4 = 20

Mean = 20

firstly u can take the value of x=3 then put the value of x in equation..then u will get y = 0 so from this equation u get this(3,0)

then do same thing take value x = 6 and then u will get the value of y = -1 therefore u will get (6,-1)

Now plot these two points (3,0) and (6,-1) on graph..

Hope it helps u..!!

Answer:

No

Step-by-step explanation:

No, because 8 - 1 ≠ 27 - 8. So, there is no common difference which is needed in order for the sequence to be arithmetic

Answer:

Step-by-step explanation:

Let shall be considering the Cosine rule in this situation.

a^2 = b^2+c^2- 2bc.cosA

Where a = ?

b = 21km

c 45km

A = 131

a^2 = 21^2+45^2-2(21*45).cos131

a^2 = 441+2025-1890(-0.6560)

a^2 = 2466+1239.951

a^2 = 3705.951

a= 60.876km

Finding the bearing of the port from the ship.

We shall be considering the Sine rule

Sin A/a = Sin B/b

Where A = ?

a = 45km

B = 131°

b = 60.876km

Sin A/45 = sin131/60.876

SinA×60.876 = 45×sin131

SinA×60.876= 45×0.7547

SinA×60.876 = 33.961

SinA= 33.961/60.876

SinA = 0.5578

A = sin^-1 0.5578

A = 33.9°

Answer: m = 1/2 or 0.5

Step-by-step explanation:

The order of operation within this problem is multiplication meaning we must divide instead.

2m = 1

2m/2 = 1/2

m = 1/2 or 0.5

Answer:

1436.76

Step-by-step explanation.

[tex]\frac{4}{3}\pi r^{3}[/tex]

that is the formula, with r being the radius.

then if you replace r with 7 that would be the answer.

pi, also equals 3.14159265359, or shortened 3.14.

so it would look like:

[tex]\frac{4}{3}*3.14*7^{3}[/tex]

in persectev i think the answer in bound to be 17/10

Answer:

x=3 y=13

Step-by-step explanation:

now you got x... substitute x value with one of the questions then you get y

-3×3+2y=17

-9+2y=17

2y=17+9

y=26/2

y=13

i hope it's clear this is how elimination method works... this is how i learned.... t☺️❤️
