Answer 1

Answer:

Answer:

41. s = semiperimeter

s = (a + b + c) /2

s = (120+170+250) /2

s = 270m

d is the correct option.

42. b is the correct option.

43. P = a + b + c

P = 120+170+250

P = 540m

a is the correct option.

44. A = √s((s-a)(s-b)(s-c))

=√270((270-120)(270-170)(270-250))

=9000m²

d is the correct option.

45. length of wire=P - space for gate

= 540 - 3

=537m

b is the correct option.

All circles are similar to each other. a. True b. False

In the circle, m arc BC = 72°. The diagram is not drawn to scale.

What is m angle BCP

Answers

Answer:

Measure of ∠BCP is 36°

Step-by-step explanation:

Given the circle in which measure of arc BC is 72°

we have to find the measure of angle BCP.

m∠BOC=∠2=72°

By theorem angle subtended at the centre is twice the angle formed at the circumference of circle.

∴ ∠2=2∠1 ⇒ 72=2∠1

⇒ ∠1=36°

By alternate segment theorem which states that

The angle formed between a chord and a tangent through one of the end points of chord is equals to angle in alternate segment.

⇒ ∠3=∠1=36°

Hence, measure of ∠BCP is 36°

Option D is correct

36 you take 72 and divide it by 2 and get 36

Ship Co. produces storage crates that require 1.2 meters of material at $.85 per meter and 01 direct labor hours at $15.00 per hour Overhead is applied at the rate of $9 per direct labor hour What is the total standard cost for one unit of product that would appear on a standard cost card?

Answers

Answer:

$3.42

Step-by-step explanation:

Meters of material required = 1.2 meters

Cost per meter of material = $0.85

Direct labor hours = 0.1

Cost of direct labor per hour = $15

Overhead rate = $9 per direct labor hour

Standard cost per unit of product :

(Direct material cost per unit + direct labor cost per unit + overhead cost per unit)

Direct material cost per unit :

Material needed × cost per meter = (1.2 × $0.85) = $1.02

Direct labor cost per unit :

Direct labor hour × cost per hour = ( 0.1 × $15) = $1.5

Overhead cost:

0.1 * $9 = $0.9

Standard cost :

($1.02 + $1.5 + $0.9) = $3.42

The product of two numbers is 37.03.If one number is 2.3,find the other.

Answers

Answer:

$\boxed{\bold{\huge{\boxed{16.1}}}}$

Step-by-step explanation:

Let the first number be x and the second number be y

So, the condition is:

$x * y = 37.03$

Given that x = 2.3

$2.3 * y = 37.03$

Dividing both sides by 2.3

$y = (37.03)/(2.3)$

$y = 16.1$

Answer:

16.1

Step-by-step explanation:

37.03/2.3 = 16.1

Question 2 of 10 What is the length of side s of the square shown below? 45 6 09 90° O A. 6 O B. 2 O C. 32 O D. 5 O E. 3 OF. 6-12

Answers

Answer:

Step-by-step explanation:

Using the cosine ratio in the right triangle and the exact value

cos45° = $(√(2) )/(2)$ , then

cos45° = $(adjacent)/(hypotenuse)$ = $(s)/(6)$ = $(√(2) )/(2)$ ( cross- multiply )

2s = 6 $√(2)$ ( divide both sides by 2 )

s = 3 $√(2)$ → C

a gasoline pump delivers 4 2/5 gallons of gas per minute. how many minutes will it take to fill a gas tank that holds 16 1/2 gallons?

Answers

The number of minutes will it take to fill a gas tank that holds $16(1)/(2)$ gallons is $3 (3)/(4)$ .

Given that, a gasoline pump delivers $4 (2)/(5)$ gallons of gas per minute.

What is the unitary method?

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

A gas tank that holds $16(1)/(2)$ gallons

Time taken to fill the gas tank

= $16(1)/(2) / 4(2)/(5)$
