A manufacturing company with 450 employees begins a new product line and must increase their number of employees by 18%. How many total employees does the company now have?

Answers

Answer:

The total number of employees company have now are 531 .

Step-by-step explanation:

As given

A manufacturing company with 450 employees begins a new product line and must increase their number of employees by 18%.

18% is written in the decimal form .

$= (18)/(100)$

= 0.18

Increase in number of employees = 0.18 × Number of employees in company .

= 0.18 × 450

= 81

Total number of employees company have now = Number of employees + Increase in number of employees

= 450 + 81

= 531

Therefore the total number of employees company have now are 531 .

You just multiply 450 by .18 and it'll give you the 18% you have to add to 450.
So the equation would look like:

450(.18)=81

Which you then add:

450+81= 531

So 531 is your total!

If the radius of a circle is 8 ft, what is the length of the diameter? 8 ft 24 ft 4 ft 16 ft

Answers

16 ft bc u would times by 2

Given that:

Radius= 8ft

Tofind:

The diameter of the given circle.

Solution:

Diameter is twice the radius. ( radius ×2)

$\large\boxed{\bold{d= r ×2}}$

In this question all the required values are given so we'll simply have to solve.

Let's substitute the values according to the formula.

$\bold{d= 8×2}$

$\large\boxed{\bold{d= 16 \ ft}}$

Therefore, the diameter of the given circle is 16 ft.

What are the solutions of the equation 9x4 – 2x2 – 7 = 0? Use u substitution to solve.

Answers

U substitution uses the variable "u" as a replacement for another variable. In this case, we will substitute in u for x^2. Since u=x^2 we can now rewrite the equation. 9u^2 -2u -7. This is factored to (u-1)(9u+7). Now put x^2 back in for u. (x^2 -1)(9x^2 +7). Factor again. (x-1)(x+1)(9x^2 + 7). Since 9x^2 + 7 doesn't factor, we don't bother with it any more.The answer is x=1 or x=-1.

Step-by-step explanation:

The endpoints of on are located at O(1, 2) and N(3, 1). Using slope-intercept form, write the equation of line on.

Answers

y = -1/2x +2 1/2
General equation;
y = mx + c

Calculating the slope;
Change in y/ (change in x) = gradient m

(2-1)/(1-3) = - 1/2

Replacing m gives;
y= -1/2x + c

Calculating the value of c
take point (1,2) above and replace y with 2 and x with 1
2=-1/2 *1 +c
c = 2 1/2
Equation then is
y = -1/2x +2 1/2
