Solve the following equation by first writing the equation in the form ax^2 = C:
t² - 490
a. t = 49
b. t = +49
C. t = 7
d. t = +7

Answer:

X=18.0

Step-by-step explanation:

It says round to the nearest tenth, which is 1 digit after the . Even though 18.02 is correct it wants you to round so X= 18.0

Final answer is X=18.0

The value of x is 18.0 rounded to nearest tenth.

Cosine law is a formula relating the length of the sides of a triangle to the cosine of one angle of the triangle.

u² = s² + t² - 2(s)(t)·cos U

We are Given Triangle with sides, 16, 30, and x, and a measure of an angle corresponding to x = 30°

Required: Value of x to the nearest tenth

Using the Cosine rule:

c² = a² + b² - 2abcos(C)

Let c = x, a = 16, b = 30

C = 30°

Thus,

c² = 16² + 30² - 2 x 16 x 30 x cos 30°

c² = 256 + 900 - 960 x 0.8660

c² = 1,156 - 831.36

c² = 324.64

c = √324.64

c = 18.017769

x ≈ 18.0 (rounded to nearest tenth)

Answer:

clerk A and clerk B can simultaneously stock a shelf in 180/13 minutes

Step-by-step explanation:

Let the first clerk be A and the second clerk be B

A can stock a shelf in 20 min

B can stock a shelf in 45 min

Consider the complete work to be W

A’s rate of stocking =  per minute

B’s rate of stocking =  per minute

When, A and B work simultaneously, rate of work done =

Total work done simulatenously =  180/13

Therefore, clerk A and clerk B can simultaneously stock a shelf in 180/13  minutes

Answer:

Step-by-step explanation:

The rate of each clerk is 1/25 and 1/45 respectively so together they can stock the shelf

t/25+t/45=1 (the least common multiple of 25 and 45 is 225)

t/25(9/9)+t/45(5/5)=1

(9t+5t)/225=1

9t+5t=225

14t=225

t=225/14 min

t=16 minutes (rounded to nearest minute)

( or 16 minutes and about four seconds :) )

12

Step-by-step explanation:

8/ (2/3) = 12

The value of number is,

⇒ x = 12

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

We have to given that;

2/3 of a number is 8

Let us assume that,

A number is, x

Hence, We can formulate;

⇒2/3 of x = 8

⇒ 2/3 × x = 8

⇒ 2x = 3 × 8

⇒ 2x = 24

⇒ x = 12

Thus, The value of number is,

⇒ x = 12

Answer:

30 by 30. Area=900

Step-by-step explanation:

The dimensions of the garden to maximize the area are length + width = 60 and the maximum area is  900 ft².

A rectangular garden will be fenced on all four sides.
120 ft. of fencing is available, what should be the dimensions of the garden to maximize the area and What is the maximum area to be determined.

The rectangle is a four-sided polygon whose opposites sides are equal and has an angle of 90° between its sides.

The perimeter of the rectangle = 120
Perimeter = 2 (length + width)
120 =2(length + width)
length + width = 120/6
length + width = 60 - - - -(1)
So, the sum of the sides of the rectangle should not increase by 120.

Now, the Maximum area of a rectangle,
Let Length  = width
Equation 1
Length + Length = 60
length = 60/2
length = 30 = width
Area of the rectangle = length * width
                                     = 30 * 30
                                     = 900 ft²
So the maximum area of the rectangle is 900ft²

Thus, the dimensions of the garden to maximize the area is length + width = 60 and maximum area is  900 ft².
