Answer:

  (c)  Yes, because the bike order meets the restrictions of 4c + 6a ≤ 120 and 4c + 4a ≤ 100

Step-by-step explanation:

Try the numbers in the constraints to see if they work.

Build hours:

  (4 h/child bike)(10 child bikes) = 40 hours

  (6 h/adult bike)(12 adult bikes) = 72 hours

  total build hours: 40 +72 = 112, less than 120; constraint is met

Test hours:

  (4 h/child bike)(10 child bikes) = 40 hours

  (4 h/adult bike)(12 adult bikes) = 48 hours

  total test hours: 40 +48 = 88, less than 100; constraint is met

__

Both constraints are met, so the order can be filled.

The system of equations is:

2b + 4.25s = 53.75

b - s = 5  

The number of bagels bought is 12 and the number of sandwiches bought is 7.

2b + 4.25s = 53.75 equation 1

b - s = 5  equation 2

Where:

The elimination method would be used to determine the required values.

Multiply equation 2 by 2

2b - 2s = 10 equation 3

Subtract equation 3 from equation 1 :

6.25s = 43.75

Divide both sides of the equation by 2.25

s = 43.75 / 6.25

s = 7

Substitute for s in equation 1:

2b + 4.25(7) = 53.75

2b + 29.75 = 53.75

2b = 53.75 - 29.75

2b = 24

b = 24 / 2

b = 12

The center of the circle is (-3, -4), and its radius is sqrt(9) = 3.

To determine the center and radius of the circle within the given equation x^(2)+y^(2)+6x+8y=-16, we need to complete the square for both x and y.

First, let's complete the square for x by adding (6/2)^2 = 9 to both sides of the equation:

x^(2) + 6x + 9 + y^(2) + 8y = -16 + 9

Simplifying this equation, we get:

(x + 3)^(2) + y^(2) + 8y = -7

Next, we complete the square for y by adding (8/2)^2 = 16 to both sides of the equation:

(x + 3)^(2) + (y + 4)^(2) = 9

Now we can see that the equation is in standard form: (x - h)^(2) + (y - k)^(2) = r^(2), where (h, k) is the center of the circle and r is its radius.

Therefore, the center and radius are (-3, -4) and 3 respectively.

It will take Flora about 1.2 hours (or 72 minutes) to travel 132 km if her speed remains constant.

The distance is calculated by the formula below,

distance = speed × time

We know that Flora travelled 55km in 30 minutes, which is 0.5 hours (since there are 60 minutes in an hour).

So, we can find Flora's speed by dividing the distance by the time:

speed = distance ÷ time = 55 km ÷ 0.5 hours = 110 km/hour

Now we can use this speed to find how long it will take her to travel 132 km:

time = distance ÷ speed = 132 km ÷ 110 km/hour ≈ 1.2 hours

Therefore, it will take Flora about 1.2 hours (or 72 minutes) to travel 132 km if her speed remains constant.

In this triangle, the product of tan A and tan C is `(BC)^2/(AB)^2`.

The given triangle ABC has angle A measuring 45 degrees, angle B measuring 90 degrees, and angle C measuring 45 degrees , Answer: `(BC)^2/(AB)^2`.

We have to find the product of tan A and tan C.

In triangle ABC, tan A and tan C are equal as the opposite and adjacent sides of angles A and C are the same.

So, we have, tan A = tan C

Therefore, the product of tan A and tan C will be equal to (tan A)^2 or (tan C)^2.

Using the formula of tan: tan A = opposite/adjacent=BC/A Band, tan C = opposite/adjacent=AB/BC.

Thus, tan A = BC/AB tan C = AB/BC Taking the ratio of these two equations, we have: tan A/tan C = BC/AB ÷ AB/BC Tan A * tan C = BC^2/AB^2So, the product of tan A and tan C is equal to `(BC)^2/(AB)^2`.

Answer:

Lucy: 10

Daniel: 37

Step-by-step explanation:

Let Daniel's age be d, and Lucy's age be l.

We can set up a system of equations.

d = 7 + 3l

2d-5l = 24

We can subsitute the value of d from the first equation into the second equation.

2*(7+3l)-5l = 24

Distribute:

14 + 6l - 5l = 24

Combine like terms:

l = 10

Plug this value back into the first equation:

d = 7 + 3*10

d = 37

The candy distributor needs to use 30 kilograms of 10% fat-content chocolate and 70 kilograms of 50% fat-content chocolate to create 100 kilograms of a 14% fat-content chocolate.

To solve this problem, we can use the method of mixture problems, which involves setting up a system of equations. Let x be the number of kilograms of the 10% fat-content chocolate and y be the number of kilograms of the 50% fat-content chocolate.

We have two equations based on the fat content and the total weight of the mixture:

0.1x + 0.5y = 0.14(100) (equation for fat content)

x + y = 100 (equation for total weight)

We can solve this system of equations using substitution or elimination. Using substitution, we can solve for x in terms of y from the second equation and substitute it into the first equation:

x = 100 - y

0.1(100 - y) + 0.5y = 0.14(100)

10 - 0.1y + 0.5y = 14

0.4y = 4

y = 10

Then we can substitute y = 10 back into the equation for x and get:

x = 100 - y = 100 - 10 = 90

By using the distributive property of subtraction, expression 11x+3y subtracted from 13x+9y is equal to 2x+6y.

The distributive property of subtraction states that when subtracting a value from a sum, the same result can be achieved by subtracting the value from each addend separately and then finding the difference between the two results.

An expression is a combination of numbers, variables, and operators, such as +, -, x, ÷, and parentheses, that represents a mathematical relationship or quantity. It does not contain an equals sign.

According to the given information:

In the given context, the word "from" means to subtract.

So, if we have to subtract 11x+3y from 13x+9y, we can rewrite it as:

(13x+9y) - (11x+3y)

Then, by using the distributive property of subtraction, we can simplify the above expression as follows:

13x+9y - 11x-3y

Now, combining like terms, we get:

2x + 6y

Therefore, 11x+3y subtracted from 13x+9y is equal to 2x+6y.

We are assuming that the random selection is without replacement, which means that once a slip is drawn, it is not put back into the hat.

There are 5 possible pairs of numbers that add up to 12 when drawing two slips of paper numbered 1 through 14 without replacement. These pairs are:

1 and 11

2 and 10

3 and 9

4 and 8

5 and 7

Next, we need to find the number of ways to draw each pair. Since the order in which the slips are drawn does not matter, each pair can be drawn in 2 different ways. So, for each of the 5 pairs, there are 2 ways to draw the pair.

Each pair of numbers can be drawn in 2 different order (the order in which the slips are drawn does not matter in this case), so the total number of ways to draw two slips so that the sum of the numbers is 12 is \(5 * 2 = 10\).
