Answer:

r = -5

Step-by-step explanation:

common ratio (r) is found be dividing one term by its preceding term:

r = 275 ÷ -55 = -5

or, r = -55 ÷ 11 = -5

Therefore, r = -5

Can someone please answer this for me

Answer:

x = 7.5

y = 75

Step-by-step explanation:

if one angle of an equilateral triangle is 60 degrees (180/3) then 4x + 2x + 2x = 8x = 60, so x = 7.5

for y, we'll have to take the right triangle. we know that 2x = 15, and MON = 60, so 180 - 60 - 15 = 105.

180 - 105 will give us y, which is 75

Answer:

$(n+2)^2+6$

Step-by-step explanation:

Pattern 1 consists of

$3+3\times 3+3$ small squares (here n = 1 and $3\times 3=(1+2)\times (1+2)$ ).

Pattern 2 consists of

$3+4\times 4+3$ small squares (here n = 2 and $4\times 4=(2+2)\times (2+2)$ ).

Pattern 3 consists of

$3+5\times 5+3$ small squares (here n = 3 and $5\times 5=(3+2)\times (3+2)$ ).

Thus, pattern n consists of

$3+(n+2)\times (n+2)+3=6+(n+2)^2$ small squares.

Expression.is of what number? Write a division expression to match this question.

nirvana33 [79]

3/4 is 1/3 of what number?

For this problem we just need to do the following division:

$\frac{x}{3}=\frac{3}{4}$

And we can solve for the value of x desired and we got multiplying both sides by 3:

$x=3(\frac{3}{4})=\frac{9}{4}$

So then we can conclude that 3/4 is 1/3 of 9/4

Answer: 9/4

Expression:

$\frac{x}{3}=\frac{3}{4}$
