Seperate the polygon into solvable shapes (ie: squares and triangles)
When I split it up, I ended up with 4 different triangles and a square.

From there, just measuer out the shapes and solve for their areas. Then add the totals, and you have your answer. In this case, it is 35.5 units^2.

Read the numbers and decide what the next number should be. 5 15 6 18 7 21 8

VikaD [51]

we have

$5,15 \\6, 18 \\7,21 \\8,?$

Let

$a1=5\\b1=15\\a2=3\\b2=18\\a3=7\\b3=21\\a4=8$

we know that

$\frac{b1}{a1}=\frac{15}{5}\\ \\b1=3*a1$

$\frac{b2}{a2}=\frac{18}{6}\\ \\b2=3*a2$

$\frac{b3}{a3}=\frac{21}{7}\\ \\b3=3*a3$

$a4=8$

the next term should be

$b4=3*a4=3*8=24$

therefore

<u>the answer is</u>

$24$

Michelle's father deposited $1,000 into a savings account when she was born. The annual interest rate is

prohojiy [21]

Answer:

Michelle's age = 16

Step-by-step explanation:

As we know,

Amount = $P (1 + r)^{t}$ where

P = Principal amount

r = rate of interest

t = time

Given ,

P = $1000

r = 4.5 % = $\frac{4.5}{100} = 0.045$

Now,

Given that Amount reaches more than $2000

⇒ $P (1 + r)^{t}$ > 2000

⇒ $1000(1 + 0.045)^{t}$ > 2000

⇒ $(1.045)^{t}$ > 2

Now,

we put the value of t from 0 , 1, 2, ..... untill the above equation does not satisfy

Now,

for t = 0

$(1.045)^{0} = 1 \ngeq 2$

for t = 1

$(1.045)^{1} = 1.045 \ngeq 2$

for t = 2

$(1.045)^{2} = 1.092 \ngeq 2$

for t = 3

$(1.045)^{3} = 1.14 \ngeq 2$

for t = 4

$(1.045)^{4} = 1.19 \ngeq 2$

for t = 5

$(1.045)^{5} = 1.25 \ngeq 2$

for t = 6

$(1.045)^{6} = 1.30 \ngeq 2$

for t = 7

$(1.045)^{7} = 1.36 \ngeq 2$

for t = 8

$(1.045)^{8} = 1.42 \ngeq 2$

for t = 9

$(1.045)^{9} = 1.48 \ngeq 2$

for t = 10

$(1.045)^{10} = 1.55 \ngeq 2$

for t = 11

$(1.045)^{11} = 1.62 \ngeq 2$

for t = 12

$(1.045)^{12} = 1.69 \ngeq 2$

for t = 13

$(1.045)^{13} = 1.77 \ngeq 2$

for t = 14

$(1.045)^{14} = 1.85 \ngeq 2$

for t = 15

$(1.045)^{15} = 1.93 \ngeq 2$

for t = 16

$(1.045)^{16} = 2.02 > 2$

It satisfies at t= 16

∴ we get

Michelle's age = 16

In triangle MNP, medians NQ and PR intersect at S. If PS = 8 and QS = 3 then which of the following is the value of NQ + PR

bija089 [108]

Answer:

(2) 22

Step-by-step explanation:

In the given triangle MNP, the medians are straight lines drawn from the angle to opposite side so as to divide the side into equal parts.

PS = 8 and QS = 3, thus;

PS = NS = 8 (congruent property of ΔRSN and ΔQSP)

QS = SP = 3 (congruence property)

So that,

NQ = NS + SQ

= 8 + 3

= 11

PR = PS + SR

= 8 + 3

= 11

Thus;

NQ + PR = 11 + 11

= 22

Therefore, NQ + PR = 22
