Answer:
0.430
Step-by-step explanation:
Product has four parts :
For proper functioning, each part must function :
Let the 4 parts be:
A, B, C and D
Proper functioning probability :
A and B = 0.79
C and D = 0.83
For proper functioning :
P(A) * P(B) * P(C) * P(D)
0.79 * 0.79 * 0.83 * 0.83
= 0.42994249
= 0.430

a farmer is creating a budget for planting soybeans and wheat. planting soybeans costs $200 per acre and planting wheat costs $500 per acre. He wants to spend no more that $100,000 planting soybeans and wheat. Write an inequality to describe the constraints. specify what each variable represents
The inequality that represents the constraint is as follows;
200x + 500y ≤ 100000
How to solve inequality?The inequality to describe the constraints is as follows;
Therefore,
let
x = acre of land use to plant soya beans
y = acre of land use to plant wheat
Therefore,
200x + 500y ≤ 100000
Hence, the inequality that represents the constraint is as follows;
200x + 500y ≤ 100000

Answer:
200x + 500y ≤ 100000
Step-by-step explanation:
Given ,
The cost of planting soybeans is $ 200 per acre
The cost of planting wheat is $ 500 per acre
The maximum amount he can spend for planting is $ 100,000
Let's assume
x = acre of land use to plant soya beans
y = acre of land use to plant wheat
We know that ,
If 'a' is the cost spend on unit item and 'b' is the number of items the total cost will be a * b
So the total amount spend for planting will be,
200x + 500y
As the amount spend cannot exceed a maximum of $ 100,000 ,
200x + 500y should be less than or equal to 100,000
Therefore we can mathematically represent it using the inequality ≤ as,
200x + 500y ≤ 100000
Hence, the inequality that represents the constraint is as follows;
200x + 500y ≤ 100000

Answer: (x-6)(x+1)
Step-by-step explanation:
Sum : x2 − 5 x- 6
x2 + x-=6 x − 6
factor pair: x 2 + x − 6 x − 6
x( x+ 1 ) − 6 ( x + 1 )
rewrite from: x (x + 1 ) − 6 ( x + 1 )
(x-6)(x+1)
Answer:
A: (x-6)(x+1)
Step-by-step explanation:
We need to find 2 numbers that add to make -5 and multiply to make -6.
We already have the numbers infront of us, so by process of elimination we can remove B and D.
For the numbers, we need a positive number and a negative number (two negatives make a positive). We can eliminate C because at first -3 multiplied by 2 is -6. However, when -3 is added to 2 we get -1.
If we expand A, it makes the expression that needs to be factorised because...
-6 × 1 = -6
-6 + 1 = -5
So expanding it properly we get.
x² - 6x + x - 6
Simplify.
x² - 5x -6
AB, CD and EF are straight lines.
AB is parallel to CD.
work out the size of angle y.
Answer:
y = 108°
Step-by-step explanation:
Since, line AB is parallel to line CD,
By the definition of corresponding angles,
m∠FPB = m∠FQD
(2x + 16)° = (3x - 12)°
3x - 2x = 16 + 12
x = 28
(3x - 12) = 3(28) - 12
= 72°
m∠FQD + m∠EQD = 180° [Linear pair of angles]
72° + y = 180°
y = 180 - 72
y = 108°

Shen invested in a savings bond for 2 years and was paid simple interest at an annual rate of 2% the total interest that he earned was $28 how much did he invest 
Answer:
Principal = $700
Step-by-step explanation:
Simple interest = principal × rate × time
Simple interest = $28
Rate = 2% = 0.02
Time = 2 years
Principal = x
Simple interest = principal × rate × time
28 = x * 0.02 * 2
28 = 0.04x
x = 28/0.04
x = $700
Principal = x = $700

The cost of a set of DVDs after a 25% markup can be represented by the expression c+0.25c . Simplify the expression.
Answer: 1.25c
Step-by-step explanation:
The original cost of the DVDs is given as c.
The cost of the DVDs after a 25% markup is: c + 0.25c to show that 25% of c was being added to c to increase the price.
As both numbers in the equation have the same variable attached, they can be added. c is assumed to be 1c when it stands alone.
= c + 0.25c
= 1c + 0.25c
= 1.25c

The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.
We have,
The y-axis is 100 units.
The x-axis is 10 units.
From the graph,
(2, 20) means 20 miles in 2 hours.
Thus,
The total number of miles is 100.
The total number of hours is 10.
(2, 20) represents 20 miles in 2 hours.

Rodney decides to pay a $200 fee in 3
payments. The first payment is 10% of the
original fee. The second payment is 25% of the
original fee. Which expressions represent the
amount of money for the third payment?
Answer:
65% of the orginal fee or $130.
Step-by-step explanation:
You didn't put the answer options so I am not sure how you want the question to be answered. There are three ways I would write it:
1: 100% = 10% + 25% + 65%
2: 200 = 20 + 50 + 130
3: 200 = (0.1 x 200) + (0.25 x 200) + (0.65 x 200)
All of them basically mean the same thing it is just a matter of how you need it written.
Based on the amount to be paid and the percentage paid in each installment, the expression for the third payment is 65% x 200.
Rodney has to pay $200 in three installments.
The third installment will be:
= Percentage in total - Percentages paid already
= 100% - 10% - 25%
= 65%
The third installment is therefore:
= Percentage to be paid x Amount
= 65% x 200

Natalie is on her school's swim team. Last year, she swam the 300-meter freestyle in 3 2/3 minutes. This year she swam a shorter distance of 200-meter freestlye in 3 minutes. What is her speed for per hour for each hour for each distanc
Answer:
4909 m/hr
6000 m/hr
Step-by-step explanation:
Last Year :
Distance = 300 m
Time = 3 2/3 minutes
Speed per hour = distance / time
Time in hour = 11/3 ÷ 60 = 0.0611111 hour
300 / 0.0611111 = 4909.0918 m /hr
= 4909 m/hr
This year :
Distance = 200 m
Time = 3 minutes
Speed per hour = distance / time
Time in hour = 3 ÷ 60 = 0.0333333 hour
200 / 0.0333333 = 6000.0060 m /hr
= 6000 m/hr
The total cost of making a daily taco special for a restaurant is represented by the function C(t)=2.5t+1, where t is the number of tacos made. How does the total cost change for every taco special the food truck makes? a: $1 b: $2.50 c: -$1 d: -$2.50
Given:
The total cost of making a daily taco special for a restaurant is represented by the function
[tex]C(t)=2.5t+1[/tex]
Where t is the number of tacos made.
To find:
The total cost change for every taco special the food truck makes.
Solution:
We have,
[tex]C(t)=2.5t+1[/tex]
Here, 1 is a constant because it is free from the variable and 2.5 is the coefficient of t.
It means, 1 represents fixed cost of making tacos but 2.5t changes with respect to t. Thus, 2.5 represents the addition cost of every taco special the food truck makes.
So, $2.5 is the total cost change for every taco special the food truck makes.
Therefore, the correct option is b.
