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.

Answers

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

Answers

Answer:

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,

[tex]\frac{1600}{4}=[/tex] 1600 ÷ 4

[tex]=1600\times \frac{1}{4}[/tex]

Therefore, Options (B) and (C) will be the correct options.

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.

Answers

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.

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?

Answers

480 people. Because 60x5=300 and 300 divided by 25=12. Lastly, 12x40=480!!

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

Ron is saving money for college. Each month he deposits 10% of his net income plus

an additional $50 into a savings account. His net income, after taxes have been taken

out, is 80% of his gross income. Find the amount that Ron saves a month when his

gross income is $2400.

Answers

Answer:

$242

Step-by-step explanation:

His Gross income a month is $2400.

Now, we are told that his net income, after taxes have been taken out, is 80% of his gross income.

Thus;

Net income a month = 80% × 2400 = $1920

Now, Each month he deposits 10% of his net income plus an additional $50 into a savings account.

This means amount saved each month is = (10% × 1920) + 50 = 192 + 50 = $242

B. 8/square root of 89

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

Answer: A) all real numbers

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.
