Answer:

12a. 2.8 units

12b. 75°

Step-by-step explanation:

The question is asking if the translated shapes dimensions are the same with the original shape. Because the shape was only translated, the shape is identical. Translation is moving a shape to a different part of the graph.

A comet passes Earth every 70 years.

Another comet passes Earth

every 75 years

If both comets pass Earth this year, how many years

will it be before they both pass Earth on the same year again?

Find the lowest common multiple of 70 years and 75 years

70 years = 70, 140, 210 , 280, 350, 420, 490, 560, 630, 700, 770, 840, 910, 980, 1050, 1120, 1190, 1260,

75 years = 75, 150, 225 , 300, 375, 450, 525, 600, 675, 750, 825, 900, 975, 1050, 1125, 1200, 1275, 1350

Lowest common multiple of 70 years and 75 years is 1,050 years

Therefore,

If both comets pass Earth this year, they both pass Earth the same year again in the next 1,050 years

Find the sum in its simplest form. 6/9 + 6/9 will give brainlist for best answer

sukhopar [10]

Answer:

→Step 1:

$\frac{6}{9} + \frac{6}{9}$

write the equation

→Step 2:

$\frac{6 + 6}{9}$

after taking LCM of 6/9 and 6/9 we get( 6+6)/9

→step 3:

$\frac{12}{9}$

after adding 6 and 6 we get 12

→Step 4:

$\frac{4}{3}$

after dividing numerator and denominator by 3 we get 4/3

→step5:

$1.334$

finally we get 1.334✓

hope it helped you:)

How is graphing a two variable inequality similar to graphing a one variable inequality on the number line?

NISA [10]

There are several ways that it is similar.

1) You still shade on the parts that satisfy the inequality (even though it is 2 dimensional instead of 1.

2) You still need to show whether or not it is "greater than" or "greater than or equal to". On a line graph you use an open or closed dot, on a graph you use a dotted or solid line.

the manager of a grocery store has taken a random sample of 100 customers the average length of time it took these 100 customers

lora16 [44]

Answer:

with a .95 probability, the sample mean will provide a margin of error 0.196

Step-by-step explanation:

margin of error (ME) from the mean can be calculated using the formula

ME= $\frac{z*s}{\sqrt{N} }$ where

z is the corresponding statistic in the .95 confidence level (1.96)

s is the population standard deviation (1 min.)

N is the sample size (100)

ME= $\frac{1.96*1}{\sqrt{100} }$ =0.196

95% confidence interval for check-out time would be 3 ±0.196 min
