Lets work backwards. π r2 = 62 cm. 62 / 3.14 = 17.75. Square root of 17.75 = 4.21. Okay, now using the radius of 4.21 we will use the formula C = 2 πr. C = 2 (3.14)(4.21) = 2 (13.22) = 26.44. So the circumference of each button is approximately 26.44 cm.

5t+5/4-1=4t-3/5<br>maths <br>class 8

Aleks [24]

Answer:

3.4

Step-by-step explanation:

5t+5/4-1=4t-3/5. cross multiply over the bracket

(5t+5)5=(4t-3)(4-1)

25t + 25 = -16t -4- 12 - 3

Combine the like terms

25t - 16t +4t = -4-12-3-25

13t = - 44

Divide both sides by 13

3.38

PLEASE HELP ME ASAP ITS A EXAM

Answer:

6x = 48, 180/z = 90, and 10y + 8 + 138 = 180

Step-by-step explanation:

48 and six x are vertical angles they form a kind of x so they are complementary or equal

180/z and the 90 degree angle are supplementary meaning they add to 180 so 90 minus 180 = 90

the same thing is true for 10y + 8 its supplementay with 138 so 10y + 8 + 138 = 180

What is the address of the element -5 in the matrix below?

Musya8 [376]

we have to find address of element -5 in the matrix

We know that

horizontal line represents number of rows

vertical line represents number of columns

We can see that

-5 is in third row

and -5 is in second column

Suppose, we have element in matrix

$b_m_n$

Here , m is number of rows

and n is number of columns

so, we got

$m=3$

$n=2$

now, we can plug these values

and we get

$b_3_2$ ............Answer
