Erika has 6.53 kilograms of apples, which is more than the 6 kilograms she needed for the recipe. Therefore, she has enough apples to make the recipe.
To determine if Erika has at least 6 kilograms of apples, we need to add the weight of all three bags of apples. The total weight of the apples is:
It is given that:
There is 2.56 kg of red apples.
There is 1.18 kg of green apples.
And, 2.79 kg of yellow Apples.
Therefore,
2.56 kg + 1.18 kg + 2.79 kg = 6.53 kg
Erica needs a certain number of apples for her recipe, i.e. 6 kg. She goes to her store and chooses three different bags of apples: a 2.56 kg bag of red apples, a 1.18 kg bag of green apples, and a 2.79 kg bag of yellow apples.
To determine if you have enough apples, you must add up the weight of all three bags. The total weight of the apples is 6.53 kg. This means that Erika has more than 6 kg of apples she needs and has enough for the recipe. It's important to note that Erica has a surplus of apples that can come in handy if she needs more apples for recipes or later.
Combining different types of apples can also add variety and flavor to your recipe.

9/4-7/3 pls answer fast
Answer: -1/12
Step-by-step explanation:
Answer:
-1/12
Step-by-step explanation:
9/4 - 7/3
To start, we need to make the denominators the same number. In order to do that, we need to identify the factor they have in common.
4, 8, 12
3, 6, 9, 12
Twelve is the common factor, so we will use this. Remember, whatever you do to the bottom, you must do to the top, and vice versa.
4 * 3 = 12
/12
3 * 9 (numerator) = 27
27/12
Now, we must figure out 7/3.
3 * 4 = 12
4 * -7 = -28
-28/12
Now, take the new fractions and subtract them.
27/12 - 28/12

A caterer charges $110 to cater a party for 10 people and $220 for 20 people. Assume the cost, y, is a linear function of the number of x people. Write an equation in slope-intercept form for this function. What does the slope represent? How much would a party for 60 people cost?
The slope-intercept definition of a linear function is given as follows:
y = mx + b.
In which:
m is the slope, representing the cost per people.b is the intercept, representing the fixed cost.Two points on the function are given as follows:
(10, 110) and (20, 220).
The slope is given by the change in the output divided by the change in the input, hence:
m = (220 - 110)/10
m = 11.
Hence:
y = 11x + b.
When x = 10, y = 110, hence the intercept b is given as follows:
110 = 11(10) + b
b = 0.
Hence the function giving the cost for x people is of;
y = 11x.
The cost for 60 people would be of:
y = 11(60)
y = $660.

find the inverse function of f(x) = 2x +3
Answer:
So the inverse function of f(x) = 2x + 3 is f⁻¹(x) = (x - 3) / 2.
Step-by-step explanation:
To find the inverse of a function, we switch the x and y variables and solve for y. So, we start with:
y = 2x + 3
Switching x and y, we get:
x = 2y + 3
Now, we solve for y:
x - 3 = 2y
y = (x - 3) / 2
So the inverse function of f(x) = 2x + 3 is f⁻¹(x) = (x - 3) / 2.
Answer & Step-by-step explanation:
To determine f's inverse function (x)= 2x + 3, we can follow these steps:
Step 1: Replace f(x) with y: y = 2x + 3
Step 2: Solve for x in terms of y:
y = 2x + 3
y - 3 = 2x
x = (y - 3) / 2
Step 3: Replace x with f^(-1)(x):
f^(-1)(x) = (x - 3) / 2
Therefore, the inverse function of f(x) = 2x + 3 is f^(-1)(x) = (x - 3) / 2.
Hope it helps!Compare Jurgis’s response after his injury to his earlier attitudes. How did his attitude change? Describe your opinion in at least four sentences
Answer:
Step-by-step explanation:
In "The Jungle" by Upton Sinclair, Jurgis is a character who starts out with a positive and optimistic outlook on life. He is full of hope and ambition when he arrives in America with his family, eager to make a better life for himself. However, after he is injured on the job and becomes unable to work, his attitude changes dramatically. He becomes disillusioned and bitter, losing his hope and faith in the American Dream.
In my opinion, Jurgis's response to his injury reflects the harsh realities of life for immigrants and the working class in America during that time. The injury not only physically incapacitates him, but it also robs him of his ability to provide for his family and live out his dreams. The experience shows the extent to which the system is stacked against those in Jurgis's position and serves as a powerful commentary on the injustices and inequalities of the time.
volume of a sphere = 4/3pir^3 where r is the radius volume of a cone = 1/3pir^2h where r is the radius and h is the height the shape below is made from a cone and a hemisphere work out the volume of the shape give your answer to the nearest integer 8cm 12cm
Answer: To find the volume of the combined shape, we need to find the volume of the cone and the volume of the hemisphere and add them together.
For the cone:
Volume = 1/3 * pi * r^2 * h
Where r is the radius and h is the height. In this case, r = 8 cm and h = 12 cm. So,
Volume = 1/3 * pi * 8^2 * 12 = (1/3) * pi * 64 * 12 = 256 * pi cm^3
For the hemisphere:
Volume = (2/3) * pi * r^3
Where r is the radius. In this case, r = 8 cm. So,
Volume = (2/3) * pi * 8^3 = (2/3) * pi * 512 cm^3
Adding the volumes of the cone and the hemisphere, we have:
Volume = 256 * pi + (2/3) * pi * 512 cm^3 = 256 * pi + 341.3333 * pi cm^3
To the nearest integer, the volume of the combined shape is:
Volume = round(256 * pi + 341.3333 * pi) = round(597.3333 * pi) = 1876 cm^3

the cost of first-class postage in 2013 was raised to 46 cents. according to the exponential regression model, what was the predicted cost for 2013? start by noting that 2013 is 63 years since 1950.
The predicted cost of postage for 2013 is 45 cents.
How to determine the predicted cost in 2013We need to use the exponential regression model to predict the cost of postage for the year 2013, given that it was 63 years since 1950.
Let's assume that the cost of postage can be modeled using the exponential function:
C(t) = a * e^(kt)
where:
C(t) is the cost of postage at time ta is the initial cost of postage (in 1950)k is the growth rate of the cost of postage (in decimal form)We can use the two data points we have to solve for a and k:
In 1950, the cost of postage was 3 cents (a = 0.03)In 2013, the cost of postage was 46 cents (C(63) = 0.46)Using the above data points, we can solve for k as follows:
0.03 = a * e^(0 * k)
0.46 = a * e^(63k)
Dividing the second equation by the first equation, we get:
15.333 = e^(63k)
Taking the natural logarithm of both sides, we get:
k = ln(15.333)/63
Evaluate
k = 0.043
Now that we have k, we can use it to predict the cost of postage in 2013:
C(63) = a * e^(63k)
C(63) = 0.03 * e^(63 * 0.043)
C(63) = 0.45
Hence, according to the exponential regression model, the cost is 45 cents.

How do you find the zeros of a function please give a detailed explanation
There are several ways to find the zeros of the function x^4–18x^2+12x+80. You can graph the equation and see where it crosses the x axis.The graph crosses at x=-4,-2. This means that -4, and -2 are roots, and (x+4) and (x+2) are factors. I like synthetic division the best when it comes to factoring. I teach synthetic division when we get to problems like this, so I will assume that you are familiar with it.First take the coefficients of the equation x^4–18x^2+12x+80 I have to usex^4 +0 x^3 –18x^2+12x+80 : 1 0 -18 12 80. I will use -4 first.If you are not supposed to graph it, then you can use synthetic division. It can take longer because you have to “guess “ at the factors using an educated guess from the factors of =/- p/q . Where p is the last coefficient and q is the first coefficient.In this case we need to find the factors of 80/1 . These are 1,2,4,5,8,10,16,20,40,80. So possible roots are +/- (1,2,4,5,8,10,16,20,40,80). Students usually start with the smaller numbers and work up, So I would try 1 first then 2 etc.Now another way to find the factors is to use 10 as x and to see what the answer is, then try to factor the results. f(x)=x^4–18x^2+12x+80 f(10)=10,000–1800+120+80=8400I can factor 8400 into 100 *6 *14, or (10+0) *(10+0)*(10–4)*(10+4). 0 is not a factor from above, but +/- 4 is. So I could try those two numbers. Looking at the possible roots using 10 as my x, I would need to look at 9,11, 8,12, 0,20 -4,26, etc

The skid marks be to the nearest foot is 913 ft.
The length of the skid marks can be calculated using the formula d = μV2/2gdf, where μ is the coefficient of static friction, V is the velocity, g is the acceleration due to gravity, and df is the drag factor. In this case, the coefficient of static friction can be assumed to be 0.9, the velocity is 35 mi/h, the acceleration due to gravity is 32.2 ft/s2, and the drag factor is 0.97.
