Answer:

Step-by-step explanation:

convert in to cm:  (28 in)(2.54 cm/in) = 71.12 cm

radius = r = D/2 = 71.12/2 = 35.56 cm

A-circle = πr² = π(35.56)² = 3973 cm²    none of the answers shown are correct!

UNLESS is the diameter 28 cm??

If so, the solution is:

A = π(28/2)² = 615.7 cm²   again, none of the answers shown are correct!

In the bag, there are 30 oranges out of a total of 70 apples and oranges.

A ratio is a comparison between two similar quantities in simplest form.

Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.

In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.

Given, In a bag of apples and oranges, the ratio of apples to oranges

is 4 : 3 and the total number of apples and oranges is 70.

Answer:

  176 +80√5

Step-by-step explanation:

You want the exact value of (1 +√5)^5.

The coefficient of the expansion are found in Pascal's triangle (attached). Row 5 is used for the 5th power:

  (a +b)^5 = a^5 +5·a^4·b + 10·a^3·b^2 +10·a^2·b^3 +5·a·b^4 +b^5

When a = 1 and b = √5, this becomes ...

  (1 +√5)^5 = 1 + 5·√5 +10·5 + 10·5√5 +5·25 +25√5

  = (1 +50 +125) +(5 +50 +25)√5

  (1 +√5)^5 = 176 +80√5

In 33 weeks, they will have sold 150 units.

What is sales of products?

Selling a good or service in exchange for cash, a benefit, or some other kind of payment is known as product sales. When a customer purchases a good or service that will meet their needs, the transaction is known as a product sale. The quantity of goods sold during a specific time period aids in calculating product sales.

Step by Step Explaination:

Equation that models the sales of the product

The equation that models the sales of the product after an initial release exists:

s = 12√4 + 10

where s denotes the total sales (in thousands)

t denotes the time in weeks

you want to replace the s with 150 in the equation and then just solve

for t.

150 = 12√4t + 10

Subtract 10 from both sides

150 - 10 = 12√4t + 10

140 = 12√4t

Divide both sides by 12      

11.66= √4t  

Taking square root on both sides of the equation.    

135.95 = 4t      

Now divide both sides by 4

33.98 = t (approximately).

so in 33 weeks, they will have sold 150 units.

33 out of 60 customers said they liked neither the service nor the food.

At a restaurant on one evening, 60 customers were surveyed about their experience. Of those customers, 41 said they liked the service, 49 said they liked the food, and 37 said they liked both the service and the food.

To answer the question of how many said they liked neither the service nor the food, we can subtract the numbers of those who liked the service, food, or both from the total number of customers.

60 customers - 41 who liked the service - 49 who liked the food - 37 who liked both = 33 customers who liked neither the service nor the food.

In conclusion, 33 out of 60 customers said they liked neither the service nor the food at the restaurant on the evening in question. This data shows that the majority of customers enjoyed their experience, with over two-thirds of customers liking either the food, the service, or both.

Other than itself, ∠FGE is an angle that is congruent to ∠FGB.

Angles that are congruent with one another include two or more angles. This means that the dimensions of these angles are same. Angles can be acute, obtuse, exterior, or interior, and the congruence of angles is unaffected by their type. Congruent angles aren't always supplementary angles, in general. Angles must be complementary in order for the sum to be 180. Since right angles and supplementary angles have the same measure and sum up to 180, they are the only angles that can be said to be congruent.

Because ∠FGE and ∠FGB are supplementary angles, so they add up to 180 degrees. Because angle ∠FGE is 90 degrees, or a right angle, that means ∠FGB must also be 90 degrees. This makes them congruent.

In this scenario, the street distance (in centimeters) would be plotted on the x-axis (x-coordinate) of the scatter plot while the weight (in Newtons) would be plotted on the y-axis (y-coordinate) of the scatter plot through the use of Microsoft Excel.

From the scatter plot (see attachment) which models the relationship between the street distance (in centimeters) and weight (in Newtons), a linear equation for the line of best fit is given by:

y = 1.30x - 2.30

If you win if you draw a card with a star, the way the game can be made fair is; C: Add a star to 1 of the blank cards.

A basic game of chance is one that considered fair if every player has an equal probability of winning. A choice is deemed to be fair if all possible options have an equal probability of being chosen.

The first one is out of the equation to win because it isn't fair.

We want a 50/50 chance to win. Thus, If we add 2 cards with stars, then the chance of winning increases by a large portion  much. However, If we take away 2 blank cards, it would be fair, but we want to still have 10 cards. Thus, the only choice left is to add a star to 1 of the blank cards.

Therefore we can conclude that the way the given game can be made fair is given by the option C to add a star.

Answer: The value of f(-1) is equal to 5(-1)^2 + (-1) + 4 = -5 + (-1) + 4 = -2

Step-by-step explanation:

To evaluate f(-1), we substitute -1 for x in the function f(x)=5x^2+x+4. This gives us f(-1)=5(-1)^2+(-1)+4. We simplify this by applying the exponent first, so (-1)^2=1. Then we substitute the result in the function, which gives us f(-1)=5(1)+(-1)+4. Now we can simplify it by adding and subtracting the values which gives us f(-1)=5+(-1)+4=8.

If someone get a 150% salary raise, it means that the current salary will be increased by 1.5 (150/100) from the current amount.

To demonstrate this, let's assume that someone's salary is $1000, if we increase it by 150% we must calculate 150% of $1000.

[tex]1000*150\%=1000*\frac{150}{100} =1500[/tex]

150% of $1000 is $1500, since the person wll get a 150% salary raise, it means that the actual salary INCREASES that value, the final salary of a person will be:

Final salary = previous salary + amount of increase

Final salary = $1000 + $1500
