Answers

Answer 1

Answer:

Answer:

42 Comedy, 49 Action, 21 Horror

Step-by-step explanation:

6 comedy : 7 action : 3 horror = 16 parts or if you think of it as a fraction, 16 is the denominator and the numbers for each ratios are the numerators

112 (the total)/16 = 7 movies per part

6 parts of comedy = 6 x 7 = 42

7 parts action = 7 x 7 =49

3 parts horror = 3 x 7 = 21

Another way to think of it is:

(ex. comedy)

6/16=x/112

(CROSS MULTIPLY HERE)

16x=672

x=42

When 47 is added to a number the result is 37 less than 7 times the number

Answers

47 is added to a number ⇒ 47 + x
37 less than 7 times the number ⇒ 7x - 37

47 + x = 7x - 37

x - 7x = -37 - 47
- 6x = -84
x = -84 / -6
x = 14

The value of the unknown number is 14.

47 + x = 7x - 37
47 + 14 = 7(14) - 37
61 = 98 - 37
61 = 61

Jasmine kept a record of how many miles she ran each week during one month week 1 distance in miles 4.754.Week 2 distance in miles 4.752.Week 3 distance in miles 5.19.Week 4 distance in miles 5.75.Order the weeks from the fewest number of miles Jasmine ran to the greatest number of miles Jasmine ran.

Answers

4.752, 4.754, 5.19, 5.75

Final answer:

To order the weeks from fewest to greatest number of miles Jasmine ran, compare the distances for each week. The weeks from fewest to greatest number of miles Jasmine ran are: Week 2, Week 1, Week 3, Week 4.

Explanation:

To order the weeks from the fewest to the greatest number of miles Jasmine ran, we can simply compare the distances for each week.

Week 2: Distance = 4.752 miles
Week 1: Distance = 4.754 miles
Week 3: Distance = 5.19 miles
Week 4: Distance = 5.75 miles

Therefore, the weeks from fewest to greatest number of miles Jasmine ran are: Week 2, Week 1, Week 3, Week 4.

Graph f(x) = (1/3)^x+1

Answers

Answer:

The graph is attached below.

Step-by-step explanation:

Given the function

$f\left(x\right)\:=\:\left(1/3\right)^x+1$

Exponentiation function have a horizontal Asymptotes.

Finding the horizontal Asymptotes

$\mathrm{Exponential\:function\:of\:the\:form}\:f\left(x\right)\:=c\cdot \:n^(ax+b)+k\:$

$\mathrm{has\:a\:horizontal\:asymptote}\:y=k\:$

$k=1$

$\mathrm{The\:horizontal\:asymptote\:is:}$

$y=1$

Finding y-intercepts

$y\mathrm{-intercept\:is\:the\:point\:on\:the\:graph\:where\:}x=0$

$y=\left((1)/(3)\right)^0+1$

$\mathrm{Apply\:rule}\:a^0=1,\:a\ne \:0$

$\left((1)/(3)\right)^0=1$

$y=1+1$

$\mathrm{Add\:the\:numbers:}\:1+1=2$

$y=2$

$\mathrm{Y\:Intercepts}:\:\left(0,\:2\right)$

How do I solve this problem? 4/9 + 2 =

Answers

you first put a 1 under the 2
than you give them the same denominator(bottom number)
that is 18/9 and 4/9
Now add them together and get 22/9
now make that into a mixed-number by dividing 22 by 9 you get 2.44

So...4/9+2 =2.44

Hope this helps
