Options (B) and (C)
Step-by-step explanation:
Farmland owned by Dwight = 1600 acres
He wants to divide his farmland into four equal parts.
So the area of each part of the land will be = [tex]\frac{\text{Area of the farmland}}{\text{Number of parts of the farmland}}[/tex] = [tex]\frac{1600}{4}[/tex]
This expression can be written in different ways,

Line crosses y axis at (0,2)
What is the domain of the radical function shown on the graph?
The domain is the set of all possible x inputs. The blue curve stretches on forever in both directions along the x axis. This means that we can plug in any x value we want, and get some y output. We don't have to worry about dividing by zero, or applying the square root of a negative number, so there are no restrictions on the domain. We can take the cube root of a negative number with no issues. For example, the cube root of -8 is -2.

Step-by-step explanation:
got it right on edge :)
Value of sin(x) = 8 / √89, 0 < x < 90.
What are trigonometric functions?Trigonometric functions can be simply defined as the functions of an angle of a triangle where 0 < x < 90°.
Formula used
In right angled triangle ABC , ∠B = 90° , ∠C = x°
cot (x )= ( Base ) / ( perpendicular)
sin ( x) = ( perpendicular ) / ( Hypotenuse )
Pythagoras theorem
(Hypotenuse)² = (Base)² + (perpendicular)²
(AC)² = (AB)² + (BC)²
Given that
cot (x) =5 / 8 , 0< x< 90
Therefore, by comparing the given values of trigonometric function with the formula ,
Base = 5
perpendicular = 8
Substitute the value in the Pythagoras theorem,
(Hypotenuse)² = 5² + 8²
⇒ (Hypotenuse)² = 25 + 64
⇒ Hypotenuse = √89
Therefore,
sin(x) = 8 / √89
Hence Value of sin(x) = 8 / √89, 0 < x < 90

Terrence drove to his sister's house, a distance of d miles. For the first 150 miles, he was able to drive relatively quickly, at 60 miles per hour. For the remaining distance, the road was rougher, and he had to slow his speed by 20 miles per hour. For each part of the journey, he was able to keep a steady speed. The time he spent driving at the faster speed was twice the time he spent driving at the slower speed.
Answer:
The total distance he drove is 350 miles, with an average speed of 46.67 miles/hour.
Step-by-step explanation:
Let [tex]t_1[/tex] and [tex]t_2[/tex] be the time of driving at a slower rate and at a faster rate respectively.
Given that the total distance = d
The speed for the first 150 miles = 60 miles/hour.
So, [tex]150=60\times t_1[/tex] [ as distance = speed x time]
[tex]\Rightarrow t_1=2.5[/tex] hours.
The remaining distance [tex]= d-150[/tex] miles.
Speed for the remaining distance = 60 miles/hour.
As the time he spent driving at the faster speed was twice the time he spent driving at the slower speed,
So, the time of driving at a faster rate, [tex]t_2 = 2t_1=2\times2.5=5[/tex] hours
So, [tex]d-150=60\times t_2[/tex] [ as distance = speed x time]
[tex]\Rightarrow d-150=20\times 5=100[/tex]
[tex]\Rightarrow d = 100+150=350[/tex] miles.
The average speed of the journey = (Total distance)/(Total time taken )
[tex]=d/(t_1+t_2)[/tex]
=350/(2.5+5)
=350/7.5
=46.67 miles/hour.
Hence, the total distance he drove is 350 miles, with an average speed of 46.67 miles/hour.

You start at (4, 6). You move up 4 units and down 8 units. Where do you end?
Answer:
(4, 2)
Step-by-step explanation:
Translation in right or left causes the x coordinate to change while translation in up or down causes the y coordinate to change.
Moving left or down causes the coordinates to be going negative.
Moving right or up causes the coordinates to be positive.
Original point (4, 6)
Up 4 units:
(4, 6 + 4) = (4, 10)
Down 8 units:
(4, 10 - 8) = (4, 2)
You end up at point (4, 2)
What value should go in the empty boxes to complete the calculation for finding the product of 0.59 × 0.37? Both numbers are the same; however, only input the number one time in your answer. 0.59 times 0.37 gives two unknown partial products. The first product is 413. The second product is 1 thousands, an unknown value in the hundreds place, an unknown value in the tens, and 0 ones. These products are being added. Numerical Answers Expected! Answer for Blank 1:
Answer:

Step-by-step explanation:
From this Given information:
We are to find the product of:
0.59
× 0.37
However, the first product is given as 413;
Also, the second product is 1 thousand, an unknown value in the hundreds place, an unknown value in the tens, and 0 ones.
Mathematically; i.e. 1 __ __ 0
i.e.
0.59
× 0.37
4 1 3
+ 1 __ __ 0
So, to work out the unknown; we look for the multiplication of:
0.59

This is calculated as:
0.59
× 0.37
4 1 3
1 7 7
0 0 0
1 1 8 3

a ferris wheel can accommodate 40 people in 25 minutes, how many people can people ride the ferris wheel in 5 hours? What's the rate per hour?
Answer:
480 in 5hrs
Rate is 96 per hour
Step-by-step explanation:
In 5 hours there are 300 minutes (5x60) and 300min/25min = 12. So 25 mins pass 12 times in 5 hours. Since each 25 mins its 40 ppl then 12x40 = 480.
480 in 5 hours so 480/5= 96 per hour
Each morning Soriano buys coffee and donut holes for his employees and clients. The following system represents the amount of coffee and donut holes bought this morning and the amount of money that he spent (in dollars). In the system, represents the number of cups of coffee that he bought and the number of cups of donut holes that he bought.
c+d=60
2.5+1.75=123.75
Part A: How many cups of coffee and donut holes did Soriano buy this morning?
Part B: How much does each cup of coffee cost?
Part C: How much does each cup of donut holes cost?
Part D: How much did Soriano spend in coffee and donut holes?
Part E: Use the elimination method to solve the system and determine the number of cups of coffee and donut holes that Soriano bought this morning.
Answer:
Part A: 60
Part B: Each cup of coffee costs 2.5 dollars
Part C: Each donut costs 1.75 dollars
Part D: Sonario spent 123.75 dollars in coffee and donut holes
Part E: The number of cups of coffee bought are 25 cups of coffee
The number of donut holes bought are 35 donut holes
Step-by-step explanation:
The given parameters are;
c + d = 60
2.5 × c + 1.75 × d = 123.75
Part A
Whereby the number of cups of coffee bought = c, and the number of donut holes bought = d, then, the total number of cups of coffee and donuts bought is c + d = 60
Part B:
From the second equation for the total cost of cups of coffee and holes of donuts, the coefficient multiplying the variable representing an item is the cost of the item
Therefore, each cup of coffee costs 2.5 dollars
Part C:
Using the method from above, each donut costs 1.75 dollars
Part D:
From the equation for the total cost, Sonario spent 123.75 dollars in coffee and donut holes
Part E:
By the elimination method, we have;
c + d = 60
∴ c = 60 - d
Eliminating c in the equation for the total cost gives;
2.5 × c + 1.75 × d = 2.5 × (60 - d) + 1.75 × d = 123.75
150 - 2.5·d + 1.75·d = 150 - 0.75·d = 123.75
150 - 123.75 = 0.75·d
26.25 = 0.75·d
d = 26.25/0.78 = 35
d = 35
c = 60 - d = 60 - 35 = 25
c = 25
∴ c = The number of cups of coffee bought = 25 cups of coffee
d = The number of donut holes bought = 35 donut holes
