Find the value of x 12 5 X

Mathematics
1 answer:
steposvetlana [31]3 years ago
5 0

Answer:

x = 13

Step-by-step explanation:

Note that the side length x is opposite of the right angle, which means that it is the hypotenuse, which will usually be denoted as c.

Set the equation:

a² + b² = c²

let:

a = 5

b = 12

c = x

Plug in the corresponding numbers (& x) to the corresponding variables:

(5)² + (12)² = (x)²

Simplify. First, solve for the power, and then add:

x² = (5²) + (12²)

x² = (5 * 5) + (12 * 12)

x² = 25 + 144

x² =  169

Next, root both sides of the equation:

√x² = √169

x = √169 = √(13 * 13) = 13

x = 13

~

Note the rules, and it should be easier:

30-60-90° = 1 , √3 , 2

45-45-90° = 1 , 1 , √2

Any other measurements use the equation:  a² + b² = c²

Amanda [17]

We are required to find an inequality which best represents the relationship between the number of hours gardening g and the total charge c

The inequality which best represents the relationship between the number of hours gardening g and the total charge c is c ≥ 15 + 12g

At least means greater than or equal to (≥)

fixed charge = $15

charges per hour = $12

Total charge = c

Number of hours = g

The inequality:

<em>Total charge ≥ fixed charge + (charges per hour × Number of hours</em>

c ≥ 15 + (12 × g)

c ≥ 15 + (12g)

c ≥ 15 + 12g

Therefore, the inequality which best represents the relationship between the number of hours gardening g and the total charge c is c ≥ 15 + 12g

muminat

The "relative frequency" is

divided by
         (total number of trials before everybody got bored and quit) .

-- The relative frequency of blue was  (20/60)  =  (33 and 1/3) % .
(Even though 38.5% of the marbles in the jar are blue,
they didn't get picked that often.)

-- The relative frequency of green was  (18/60)  =  30 % .
(Even though only 26.9% of the marbles in the jar are green,
they got picked more often than that.)

-- The relative frequency of red was  (22/60)  =  (36 and 2/3) % .
(Even though 42.3% of the marbles in the jar are red,
they didn't get picked that often.)

1.) The check number on a check:
ziro4ka [17]

Answer:

D) Identifies the transaction and is located at the top right corner of the check

Step-by-step explanation:

The check number on a check is the number located at the top right corner of the check, and it can also be found at the bottom of the check, located in lower right corner after the routing number and the account number

The check number aids in the tracking and identifying bank transactions such as to identify checks that the bank has processed and to know outstanding checks that are yet to be processed.

The check number also aids in balancing of the checkbook.

Therefore, the check number on a check identifies the transactions and is located at the top right corner of the check.

Question 6
Aleksandr-060686 [28]

Answer:

33 children

62 adults

Step-by-step explanation:

Set up 2 equations (a=adults c=children)

The first equation will be 3.25(a)+3 = 300.5

The second equation will be a + c = 95

Subtract c from both sides to get:

a = 95 - c

Replace c in the 1st equation to get:

3.25(95-c) + 3c = 300.5

Distribute 3.25 to 95 and -c:

308.75 - 3.25c + 3c = 300.5

Subtract 308.75 from both sides:

-3.25c + 3c = 300.5 - 308.75

Combine like terms:

-0.25c = -8.25

Divide by -0.25

children = 33

Subtract 33 from 95 to get

adults = 62
