<h3>Answer:  B. 6</h3>

Explanation:

The triangles are similar. We can use the SAS similarity theorem to prove that claim.

Because the triangles are similar, the corresponding sides form a proportion like shown below

12/8 = 9/x

12x = 8*9 ... cross multiply

12x = 72

x = 72/12

x = 6 which is why the answer is choice B

I need to put these nine cards into three groups according to similarities I see... but I don't see any similarities! Please hel

Have you learned slope yet? Pick two points from the graph and do x-y on the top and x-y on the bottom. That would give you your slope then you can graph it. For example (-2,-1) (-1,1)
-2-(-1)
-1-1
Then that would give you -1/-2 so technically -1/2<< this is what you graph

The experimental probability Pa that Amir will make a basket is 0.4;

Pa = 0.4

the experimental probability Pj that juju with make the same basket is 0.6;

Pj = 0.6

Total number of shoot Nt = 150

Number of basket Amir will make is;

Na = Pa × Nt

Na = 0.4 × 150

Na = 60 basket

Number of basket juju will make is;

Nj = Pj × Nt

Nj = 0.6 × 150

Nj = 90 basket

Sandra deposited $2,500 into a simple interest account.
MakcuM [25]

Answer:

240$

Step-by-step explanation:

we know that

The simple interest formula is equal to

I=P(rt)

where

I is the Final Interest Value

P is the Principal amount of money to be invested

r is the rate of interest  

t is Number of Time Periods

in this problem we have

Sandra

t = 1 year

I= $75

P= $2,500

r= ?

substitute in the formula above

75=2,500 (r(1))

solve for r

r=75/2,500)

r= 0.03

Convert to percentage form

r= 0.03 * 100 = 3%

Ron

t=1 year

I = ?

P= 8,000

r= 0.03

substitute in the formula of interest

I = 8,000(0.03 *1)

I = $240

How do u find the mean median mode and range?
seropon [69]
Mean is the average. So you add up all the numbers and divide by how many numbers there were.

Mode is the number that occurred the most.

Median is the number that is in the middle when you list the numbers from least to greatest or greatest to least.

Range is calculated when you subtract the biggest number in the group by the smallest number.
