I guess you mean 4/5 and 3/5

this is a right angled triangle with side 3-4-5 so 5 is the hypotenuse

sin x = opp / hyp = 4/5 so the opposite side is 4
cos x = adj/hyp = 3/5 so the adjacent side = 3

so tan x = opp/adj = 4/3

replace x = 7 into the equation

f(7) = 7/9 - squared root (7-3)

f(7) = 7/9 - squared root (4)

f(7) = 7/9 - 2

f(7) = -11/9

f(7) = -1.22

)) Omar used 28 centimeters of tape to wrap 4 presents. How much tape will Omar need in

pav-90 [236]

Answer:

He would need 42 cm *or 14cm

Step-by-step explanation:

28/4 is 7

6 x 7 is 42

that means that he would need 42 cm of tape

4 to 28

6 to 42

*If he already has 4 presents done and he needs to 2 more present then he would need 14 cm, 2 x 7 is 14

How do i solve this question

Ludmilka [50]

Answer:

$a\frac{c}{8\pi b}$

Step-by-step explanation:

Divide both sides by $8\pi b$

$\frac{8\pi ab}{8\pi b} =\frac{c}{8\pi b}$

Simplify:

$a\frac{c}{8\pi b}$ ; $a\frac{c}{8\pi b}; b\neq 0$

For each pair of numbers, tell: By what percent of the first number is the second number larger? By what percent of the second n

snow_lady [41]

Answer:

Part A: 100%
Part B: 50%

Step-by-step explanation:

The difference between 10 and 5 is 5

5 is 100% of 5, so 10 is 100% greater than 5 (part A)

5/5 = 1 = 100%

5 is 50% of 10, so 5 is 50% less than 10 (part B)

5/10 = 1/2 = 50%

Part A is 100%, and Part B is 50%

the quality rating of 8 movies showing at a movie theater near you is 5.6, 7.9, 7.0, 5.9, 7.8, 6.2, 6.4, and 5.2. What do the ni

-Dominant- [34]

Answer:

5.6

Step-by-step explanation:

Given :

Quality rating for 8 movies :

5.6, 7.9, 7.0, 5.9, 7.8, 6.2, 6.4, 5.2

Let rating for the 9th movie = x

Average quality rating olfor the 9 movies = 6.4

To find x :

Sum of all ratings / number of ratings = 6.4

(5.6 + 7.9 + 7.0 + 5.9 + 7.8 + 6.2 + 6.4 + 5.2 + x) / 9 = 6.4

(52 + x) / 9 = 6.4

52 + x = 57.6

x = 57.6 - 52

x = 5.6
