In a company, 65% of the workers are women. If 1820 people work for the company who are men, how many workers are there in all?
Answer:
women=x=65%
so men=100-65=35%=1820
let total workers be y
atq....y×35/100=1820=y=5200workers
one number is 5 times another number.their sum is 90.find the numbers.
Step-by-step explanation:
let both unknowns be x and y
x = 5y. ......(1)
x + y = 90. ......(2)
sub eqn (1) into eqn (2)
5y + y = 90
6y = 90
y = 90/6
= 15
sub y = 15 to eqn (1)
x = 5y
x = 5 × 15
× = 75

Find a solution to the linear equation y=−x+7 by filling in the boxes with a valid value of x and y.
Answer:
[tex](x,y) = (0,7)[/tex]
[tex](x,y) = (3,7)[/tex]
Step-by-step explanation:
The question and the attached image are different. However, the attached image answers the question y = -4 correctly.
So, I will solve for: [tex]y = -x + 7[/tex]
Given
[tex]y = -x + 7[/tex]
Required
Possible values of x and y
Let x = 0:
[tex]y = -x + 7[/tex]
[tex]y = -0 + 7[/tex]
[tex]y = 7[/tex]
So, we have:
[tex](x,y) = (0,7)[/tex]
Let y = 4
[tex]y = -x + 7[/tex]
[tex]4 = -x + 7[/tex]
Collect Like Terms
[tex]x = -4 + 7[/tex]
[tex]x =3[/tex]
So, we have:
[tex](x,y) = (3,7)[/tex]
So, all you need to do is: assume a value for either x or y, then solve for the other variable.
Bradley's Copiers sells and repairs photocopy machines. The manager needs weekly forecasts of service calls so that he can schedule service personnel. Use the actual demand in the first period for the forecast for the first week so error measurement begins in the second week. The manager uses exponential smoothing with a = 0.1. Forecast the number of calls for week 6, which is next week.

4 27
5 25
The forecast for week 6 is ________ service calls.
Answer:
28.86
Step-by-step explanation:
According to the scenario, computation of given data are as follows,
Exponential smoothing a = 0.1
we can calculate forecast for each week by using following formula,
Forecast for week = Forecast of last week + a × ( actual calls of last week - forecast of last week)
By using this method, forecast for all week are as follows

. Given that r satisfies the inequality 20.x > 33,
find the smallest value of x if .r is a prime number.
Answer: x = 2.
Step-by-step explanation:
By an online search, i found that the question is:
"Given that x satisfies the inequality 20*x > 33, find the smallest value of x if x is a prime number."
To find the smallest value of x we need to input different possible values of x (where we have the condition that x must be a prime number) and see which one is the first one that makes the inequality true.
The prime numbers are:
2, 3, 5, ....
Let's start with the smaller one, x = 2
So we input it in the inequality and get:
20*2 > 33
40 > 33
this is true.
Then we can have x = 2, which is the smaller prime number that satisfies the inequality.

A coin is flipped and a number cube is rolled.Use a tree diagram to find the probability of getting heads and a number greater than 2?
For the coin: 2 possibilities, either head or tail. So probability of head is 1/2.
For the cube (assuming numbers are 1 to 6): 6 possibilities (1 2 3 4 5 6). We have 3 odd numbers, so probability of odd number is 3/6=1/2.
You want both head and an odd number, so you multiply the 2 probabilities: 1/2×1/2=1/4.
So the answer is 1/4.
You can use a tree to better understand probabilities.
Elsa, Chang, and Bob have a total of 104 in their wallets. Chang has 3 times what Bob has. Elsa has 6 more than Bob. How much does each have?
Answer:
Bob=19.60
Elsa=25.60
Chang=58.80
Step-by-step explanation:
(E)lsa + (C)hang + (B)ob=104
C=3B
E=B+6
substitute
(B+6)+3B+B=104
5B+6=104
5B=98
5B/5=98/5
B=19.60
E=19.60+6=25.60
C=3(19.60)=58.80
6. Write an equation for a line that passes through (6, 12) and (10, 20).
Answer:
Step-by-step explanation:
Y = mx +b / Slope intercept form
mx - y = -b / Standard form
6m -2 = -b / Plug in ( 6,2)
-9m -10 = -b / Plug in ( -9, 10)
Solve the system of equation for m and b.
6m -2 = -9m -10 , then 15m = -8 m = -8/15
b = -6m +2 ,then b= -6 ( -8/ 15) +2 = 78/15
-8/15 X - y = - 78/15
8X +15y = 78 / Equation of in standard form
Note: This is a different methods of solving this problem. All methods find their roots coming from the basic premises.
Equation of a line in the slope intersect form is
Y = mx +b
To convert to standard form of ax + by =c
Simply move over the parameters
mx - y = -b where a = m , and c = -b
Then we feed coordinates of 2 points in there
make a 2 equation with 2 unknown( m,b) to
solve.
For a large order, Mr. Magoo made 3/8 kg of fudge in his bakery. He then got 1/6 kg from his sister’s bakery. If he needs a total of 1 1/2 kg, how much more fudge does he need to make? Put your answer in fraction form. Example: Mr. Magoo needs to make #/# more fudge.
(PS: Please show your work)
Answer:
Amount fudge he needs = 23/24 kg
Step-by-step explanation:
Given:
Total fudge wants = 1[tex]\frac{1}{2}[/tex] = 3/2 kg
His sister gave = 1/6 kg
He make = 3/8 kg
Find:
Amount fudge he needs
Computation:
Amount fudge he needs = Total fudge wants - His sister gave - He make
Amount fudge he needs = 3/2 - 1/6 - 3/8
Amount fudge he needs = 23/24 kg

the length of the rectangle is 7 cm less than 4 times its width the area is 15 square cm
Answer:
I guess the answer is 4.4 cm or 22/5 cm
Step-by-step explanation:
AREA= 15cm^2
Let the Breadth be x
Length= 4x-7
Area = l×b
15 = 4x-7×x
15+7=4x+x
22=5x
22÷5=x
4.4=x
Therefore, Breadth= 4.4cm Length= 10.6cm

-8x is less than or equal to 32
What is the inequalities that are possible.
Answer:
We conclude that:
[tex]-8x\le \:32\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\ge \:-4\:\\ \:\mathrm{Interval\:Notation:}&\:[-4,\:\infty \:)\end{bmatrix}[/tex]
The solution graph on the number line is also attached.
Step-by-step explanation:
Given the inequality
[tex]-8x\:\le 32[/tex]
Solving the inequality
[tex]-8x\:\le 32[/tex]
Multiply both sides by -1 (reverse the inequality)
[tex]\left(-8x\right)\left(-1\right)\ge \:32\left(-1\right)[/tex]
Simplify
[tex]8x\ge \:-32[/tex]
Divide both sides by 8
[tex]\frac{8x}{8}\ge \frac{-32}{8}[/tex]
Simplify
[tex]x\ge \:-4[/tex]
Therefore, we conclude that:
[tex]-8x\le \:32\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\ge \:-4\:\\ \:\mathrm{Interval\:Notation:}&\:[-4,\:\infty \:)\end{bmatrix}[/tex]

In ΔIJK, k = 7.2 cm, ∠J=55° and ∠K=67°. Find the length of i, to the nearest 10th of a centimeter.
Answer:
6.6
Step-by-step explanation:
The length of i is 6.6 units(after the nearest 10th of a centimeter) if in ΔIJK, k = 7.2 cm, ∠J=55°, and ∠K=67°.
What is the triangle?The triangle can be defined as a three-sided polygon in geometry and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.
We have a triangle:
As we know the sum of the triangle is 180°
So I = 180 - 55 - 67 = 58°
Applying sin law to calculate the value of i:
[tex]\rm \frac{i}{sin58} = \frac{k}{sin67}[/tex]
[tex]\rm i = \frac{7.3\times sin 58}{sin67}[/tex]
i = 6.633 units ≈ 6.6 units (sin58 = 0.848, and sin67 = 0.920)
Thus, the length of i is 6.6 units(after the nearest 10th of a centimeter) if in ΔIJK, k = 7.2 cm, ∠J=55°, and ∠K=67°.
