Morgan uses 1/4 of her supply of raisins to make trail mix and 3/8 of her supply of raisins to make cookies. If Morgan uses 5 pounds of raisins, how many pounds of raisins are in her supply?

Answers

There are 8 pounds of raisins in Morgan's supply.

Let us say there are 'a' pounds of raisins in her supply.

What is a fraction?

Fraction is a manner to represent part of a whole.

Raisins used to make trail mix = 1/4 of a = 1/4 a

Raisins used to make cookies = 3/8 of a = 3/8 a

It is given that:

Morgan uses 5 pounds of raisins,

[tex]\frac{1}{4} a+\frac{3}{8} a=5[/tex]

[tex]\frac{5}{8} a = 5\\\\a=8[/tex]

Therefore, there are 8 pounds of raisins in Morgan's supply.

Morgan's total supply of raisins is 8 pounds.

Let's denote the total supply of raisins by R. According to the problem, Morgan uses 1/4 of her supply to make trail mix and 3/8 of her supply to make cookies. Together, this amounts to a total of five pounds of raisins used.

We set up the equation to represent the total amount of raisins used:

1/4 R + 3/8 R = 5

We need to find a common denominator to combine the fractions. Here, the common denominator is 8:

(2/8) R + (3/8) R = 5

Combining the fractions gives:

(5/8) R = 5

To isolate R, we multiply both sides of the equation by the reciprocal of 5/8, which is 8/5:

R = 5 * 8/5

When we simplify, we get:

R = 8

So, Morgan's total supply of raisins is 8 pounds.

A camera manufacturer spends $2,100 each day for overhead expenses plus $9 per camera for labor and materials. The cameras sell for $14 each. a. How many cameras must the company sell in one day to equal its daily costs? b. If the manufacturer can increase production by 50 cameras per day, what would their daily profit be?

Answers

A. The profit for each camera itself is $5 a camera. So, to make $2,100 dollars they would have to sell 420 cameras (2,100 / 5 = 420).

B. If they sold an extra 50 cameras a day, since they make $5 a camera, that would give them an extra profit of $250 a day.

A. The company must sell 420 cameras, to make it equal to daily costs.
B. For making 50 more cameras each day, they'd make $250 dollars more per 50 cameras.

A. To find this, you can simply multiply 420 by $14. This will give you how much they make from selling that many cameras ($5,880). Next you need to multiply 420 by 9 (labor an material cost per camera), then add $2,100 (expenses). This will give you the same cost ($5,880), thus making them equal, and proving 420 is the answer.

B. To find this, you do the same steps as above, by replacing 420 with 470, (470*$14 = $6,580) and (470*9 + $2,100 = $6,330). Then you subtract $6,330 from $6,580. Thus getting $250.

#3 Q. the diagrams solve please

Answers

Its the first one, 22.5. This is because... if you multiply 5 and 4, you would get 20, the area of the square. You then have to multiply 1 and 5 to get 5 and divide it by 2 to get the area of the triangle which would be 2.5, then add 2.5 to 20 and get 22.5.
Hope this helps :)

Answer:
area = 22.5 ft²

Explanation:
The total area can be calculated by summing the areas of the rectangle and the triangle.

1- getting the area of the rectangle:
area of square = length * width
In the given, we have:
length = 4 ft
width = 5 ft
Therefore:
area of rectangle = 4 * 5 = 20 ft²

2- getting the area of the triangle:
area of triangle = 0.5 * base * height
In the given, we have:
base = 5 ft
height = 1 ft
Therefore:
area of triangle = 0.5 * 5 * 1 = 2.5 ft²

3- getting the total area:
Total area = area of rectangle + area of triangle
Total area = 20 + 2.5 = 22.5 ft²

Hope this helps :)

The first thing you need to do is get a graph for the corn. This one is not very good, but it will get you an answer. While the potatoes graph is going from 50000 to 40000 (slowly), the corn graph is going up like a rocket trajectory. So eventually, the Baker family will produce more corn than potatoes. That's D.

Answer D.

Problems with AB and C
A
The problem with A is that they won't always produce more potatoes than corn. That will happen only in the beginning.

Two functions are represented in different ways. Function 1: y = 32x + 45 Function 2: x y 0 65 1 85 2 105 3 125 Which statements are true? Select each correct answer. Function 1 has a greater rate of change than function 2. Function 2 has a greater rate of change than function 1. Function 1 has a greater y-intercept than function 2. Function 2 has a greater y-intercept than function 1.

Answers

Function 1: y = 32x + 45
rate of change = 32
y-intercept = 45 when x = 0

Function 2: x y 0 65 1 85 2 105 3 125
rate of change = (85-65)/(1-0) = 20
y-intercept = 65 when x = 0

So the following statements are correct:

Function 1 has a greater rate of change than function 2.

Function 2 has a greater y-intercept than function 1.

Answer:

Step-by-step explanation:

Function 1: y = 32x + 45 <- 45 is y-intercept

Function 2: x y 0 65 <- 65 is y-intercept

So Function 2 has a greater y-intercept than function 1.

Function 1: y = 32x + ... <- 32 is rate of change

Function 2: x y 0 65 1 85

rate of change = 85 - 65 = 20

So Function 1 has a greater rate of change than function 2.

778*12

Answer is=9336

-Charlie

Final answer:

To multiply 12 by 778, one needs to perform the standard multiplication process. Multiplying each digit of 12 by 778 individually and then adding the results provides the final answer, which is 9336.

Explanation:

The student's question involves performing a multiplication operation, specifically 12 multiplied by 778. To solve this without a calculator, one can use a standard multiplication technique as follows:

Write down the two numbers, with 778 above 12.

First, multiply 2 (the rightmost digit of the lower number) by 778 to get 1556.

Next, multiply 1 (the leftmost digit of the lower number) by 778 and remember to add a zero at the end (because it represents the tens place), which gives us 7780.

Add the two results, 1556 and 7780, to get the final answer, which is 9336.

The result of 12 times 778 is 9336.

The value of (a-1)+a^2-b^2/1-ab+2(a-b)/2b when a=2 and b=-1 is ?

Answers

The value of (a-1)+a^2-b^2/1-ab+2(a-b)/2b when a=2 and b=-1 will be evaluated as follows:
substituting the values in the expression we obtain:
(2-1)+2^2-(-1)^2/1-(2*(-1))+2(2-(-1))/(2(-1))
simplifying the above we get:
1+4-1/1-(-2)+2(2+1)/(-2)
=1+4-1+2(3)/(-2)
=1+4-1-3

Answer: 1

Final answer:

The value of the expression (a-1) + a^2 - b^2 / (1-ab) + 2(a - b) / (2b) when a=2 and b=-1 is -5/3.

Explanation:

To calculate the given expression when a=2 and b=-1, we first plug these values into the expression, which is (a - 1) + a^2 - b^2 / (1 - ab) + 2(a - b) / (2b). After substitution, it simplifies as follows:

The term (a - 1) becomes (2 - 1), which equals 1.

The term a^2 - b^2 becomes 2^2 - (-1)^2, which simplifies to 4 - 1 = 3.

The denominator 1-ab becomes 1 - (2)(-1), which equals 1 + 2 = 3.

The term 2(a - b) becomes 2(2 - (-1)), which is 2(3) = 6.

The denominator 2b becomes 2(-1), which is -2.

Now, the full expression simplifies to (1 + 3) / 3 + 6 / -2. Simplifying further, we get 4 / 3 + (-3), which equals to 4/3 - 3/1. After finding a common denominator, the expression simplifies to (4 - 9) / 3, which is -5/3.

Therefore, the value of the expression when a=2 and b=-1 is -5/3.

An experienced roofer can work twice as fast as her helper. working together, they can shingle a new section of roof in 4 hours. how long would it take the experienced roofer, working alone, to complete the same job?

Answers

Final answer:

The problem solves for the time it would take the roofer to work alone, by first determining the shared work rate. The helper works at rate x and the roofer at rate 2x (twice as fast). They complete 1 roof in 4 hours working together, thus their combined rate is 1/12 roof per hour. So, the roofer’s individual rate is 1/6 roof per hour, meaning she can finish the job alone in 6 hours.

Explanation:

To solve this problem, we'll use the equation for work which is work = rate x time. Let's say the helper's rate of work as 1x and the roofer's rate as 2x, because the roofer can work twice as fast as the helper.

Bearing in mind that the total time it takes both of them to shingle the roof is 4 hours, according to the problem, we can represent this relationship as this equation: (2x + x) * 4 = 1 roof. This simplifies to 12x = 1, meaning the rate at which they work together is x = 1/12 roof per hour.

Thus, the roofer’s individual rate of work is 2x = 2/12 roof per hour = 1/6 roof per hour. Therefore, to calculate how much time it would take for the roofer to do the job alone, we simply divide the total task (1 roof) by the roofer’s rate of work, 1/(1/6) = 6 hours.

Final answer:

By setting up and solving an algebraic equation based on the given conditions in the problem, we find that it would take the experienced roofer alone 3 hours to complete the same job.

Explanation:

The problem is related to work rate and could be solved using algebra. Let's denote by X the time (in hours) it takes for the helper to complete the job alone. Considering that an experienced roofer can work twice as fast as her helper, the roofer could complete the same job alone in X/2 hours. From the problem, we know that when working together, they can complete the job in 4 hours. This means that the amount of work they do together in one hour (1/4) is equal to the sum of the amounts of work done by each in one hour (1/X + 2/X). By solving this equation, we get X = 6. So, it would take the helper 6 hours to complete the job, which means it would take the experienced roofer half of this time, which is 3 hours.

1. As you can see in the figure attached, the blue parabola has the function f(x)=x^2. This is the patern function. By definition, this is the most basic function of the quadratics functions.

2. The red parabola is shifted 2 units to the -y axis and is wider than the first one, by multiplying the variable x. Therefore. As you can see, the correct function that represents this parabola is the function of the option D
3. If you want to verify it, you can give values to x and plot each point on a graph.

If you observe the two graphs you can note that:

a) F(x) is wider than G(x)
This can be obtained by multiplying the function by a value with magnitude less than 1.

b) F(x) is shifted down
This can be obtained by subtracting a number from the function value.

From the given option, only option D satisfies these conditions.
