Can you please help me??

Answer:

7c - 13

Step-by-step explanation:

Answer:

f = 3

Step-by-step explanation:

Given the equation cos(22f − 1) = sin(7f + 4), the following steps must be followed in order to get the value of f;

From the trigonometry identity, sin(90-theta) = cos theta.

cos(22f-1) = sin (90-(22f-1))

cos(22f-1) = sin (90-22f+1)

cos(22f-1) = sin (91-22f)... 3

substituting eqn 3 into the original equation given, we will have;

sin (91-22f) = sin(7f + 4)

91-22f = 7f+4

7f+22f = 91-4

29f = 87

f = 87/29

f = 3

Answer:30cm3

Step-by-step explanation:

10 x 15=150

150 / 2 = 75

75 x 12 = 900

900 / 3 = 30cm3

Answer:

38 + (-49) = -11

Step-by-step explanation:

-100 - (-11) = -89

Answer:

15/70, first option

Step-by-step explanation:

if you multiply the numerators and denomenators together, you get 15/70. you're able to reduce this, but it looks like the answer doesn't want you to reduce it :)

=======================================================

Explanation:

We multiply the numbers across the top (numerator) to get 3*5 = 15

Then across the bottom (denominator), we multiply the values to get 10*7 = 70

So we get [tex]\frac{3}{10}\times\frac{5}{7} = \frac{3\times 5}{10\times7} = \frac{15}{70}[/tex]

That's how we end up with 15/70

------------------------------

Extra info:

Note how 15 and 70 have the GCF 5, so we can divide both values by 5

This means 15/70 reduces to 3/14; however, your teacher has decided not to reduce (since 3/14 is not one of the answers). So that means we should stick with 15/70 instead.

Answer:

3/17×100= approximately 17.6

Step-by-step explanation:

if you have 1,2,4,5,10.20,25,50, you'll multiply both sides by a number that this number when you multiply it by the denominator it will be 100

if any other numbers you can multiply immediately by 100

Answer:

≈0.669

Step-by-step explanation:

a=√(c^2-b^2)

a=√(65^2-56^2)

a=33, a is the final side

tan = O/A

tan = 33/56

tan ≈ 0.669

Answer:

Step-by-step explanation:

A. "a pair of pants originally priced at &40$ and a shirt originally priced at $45. He pays $55"—correct

(1-0.30)$40 + (1-0.40)$45 = $55

B. "Mary buys two shirts originally priced at $25. She will pay $35."—incorrect

2×(1-0.40)$25 = $30

C. "a pack of four shirts on sale for $37.80. The pack of shirts was originally priced at $54"—incorrect

(1-0.40)$54 = $32.40

D. "a pair of pants for sale price of $40.60. The pair of pants was originally priced at $58."—correct

(1-0.30)$58 = $40.60

Step-by-step explanation:

12^2 x 3.14=452.16

452.16 x 28=12,660.48

12,660.48/3=4,220.16

4,220.16 is the answer

Answer:

b.

Step-by-step explanation:

it's not a function or relation because when you use the vertical line test the line will pass through 2 other lines

Answer:

I believe it would equal .5

Step-by-step explanation:

Answer:

1/2

Step-by-step explanation:

1 3/4 is equal to 7/4.

7/4 times 2/7;

you can cancell to get rid of the sevens so it is 1/4 times 2/1

you can also cancel the two and convert the 4 to a two; 1/2 times 1

so the answer is 1/2.

Hope this helps :).

Answer:4

Step-by-step explanation:

It’s 4

Answer:

8*√100-4^2*5=

0

Step-by-step explanation:

Part A: The measure of angle x would be 53 because X= 115 - 62

Part B: APQ and PRD are alternate interior angles which means they need to equal each other, so APQ plus QPR equals PRD. I found angle x by adding  APQ + QPR = PRD  

Hope I helped, I spent a lot of time on this ^_^!

Step-by-step explanation: LOLLLLL is that rock lee form Naruto :D

Answer:

21 : 28 = 3 : 4

96 : 32 = 3 : 1

22 : 33 = 2 : 3

12 : 36 = 1 : 3

72 : 56 = 9 : 7

54 : 63 = 6 : 7

Answer:

false

Step-by-step explanation:

3x+4y=24 multiplied by 2 equals: 6x+8y=48

if you subtract 6x+8y=24 from 6x+8y=48, you get 0=24, which is not true. Therefore the statement is false.

Answer:

The metric system is an alternative system of measurement used in most countries, as well as in the United States. The metric system is based on joining one of a series of prefixes, including kilo-, hecto-, deka-, deci-, centi-, and milli-, with a base unit of measurement, such as meter, liter, or gram.

Answer:

im gouing to use 3 hours as an example so the first hour is 5 dollars and 8 dollars for each additional hour there are 2 additional hours which would be 16 dollars from the additional hours and plus 5 dollars from the first hour so 21 dollars

and the other option like i said earlier 3 hours is the example so 6*2 becasue their are 2 additional hours which is 12 plus 15 dollars from the first hour so 27 dollars

so the answer would be charge 15 dollars for the first hour and 6 for additional hour

can i get brainly please
