Answer:
390
Step-by-step explanation:
99+98+97+96=390
Answer:
394
Step-by-step explanation:
The largest number is 100 since it says none greater than 100. We can have 100
The next number is 99 since it is not equal to 100 and is the next largest number
The next number is 98 since it is not equal to 100 or 99 and is the next largest number
The last number is 97 since it is not equal to 100 or 99 or 98 and is the next largest number
The sum of the 4 numbers is
100+99+98+97 =394
Callie has a new kitten. The kitten weighs 3 pounds less than half the weight of Callie's cat. Together the cat and the kitten weigh 18 pounds. Which system of equations could be used to find the weight of each animal?
Answer: C
Step-by-step explanation:
First let’s identify that:
y = the kitten
x = the cat
Part 1 : The kitten weighs 3 pounds less than half the weight of Callie's cat.
We know that the kitten is half the size of the cat, which means the equation now looks like this:
x = [tex]\frac{1}{2}[/tex]y
But we also know that the kitten is 3 less than that equation, so now the equation is:
x = [tex]\frac{1}{2}[/tex]y -3
Part 2: Together the cat and the kitten weigh 18 pounds
Now, we have to use the other statement:
y + x = 18
But, that’s not one of the options, so we have to switch the x around and make it negative.
y = -x + 18
These are your answers!
The system of equations could be used to find the weight of each animal is option C.
Calculation of an equation:Since Callie has a new kitten. The kitten weighs 3 pounds less than half the weight of Callie's cat. Together the cat and the kitten weigh 18 pounds.
Here we assume the kitten be x and cat be y
So, the equation should be
[tex]y = 1\div 2x - 3\\\\[/tex]
And,
y = -x + 18

y = -3x + 4
y= 1
And SHOW YOUR WORK PLEASE!!!!
Answer:
x = 1
y = 1
Step-by-step explanation:
Since it gives you the value of y already, all you need to do is plug it into the equation, like so:
y = -3x + 4
1 = -3x + 4
Now, subtract 4 from both sides:
1 = -3x + 4
-4 - 4
________
-3 = -3x
Finally, divide both sides by -3:
-3 = -3x
1 = x
So now you have, x = 1 and y = 1.

The lifespan of zebras in a particular zoo are normally distributed. the average zebra lives 20.5 years the standard deviation is 3.9 years.
use the empirical rule (68-95-99.7%) to estimate the probability of a zebra living less than 32.2 years.
The empirical rule tells us that approximately 99.7% of data in a normal distribution falls within three standard deviations of the mean. The lifespan of 32.2 years is three standard deviations from the mean lifespan of zebras in the zoo, so the probability of a zebra living less than 32.2 years is about 99.7%, which is very high.
To the lifespan of zebras being normally distributed, with a mean of 20.5 years and a standard deviation of 3.9 years.
To estimate the probability of a zebra living less than 32.2 years, we can use the empirical rule, also known as the 68-95-99.7 rule. This rule states that for a normal distribution:
Approximately 68% of the data falls within one standard deviation of the mean (both above and below).
About 95% fall within two standard deviations.
Almost all, or 99.7%, fall within three standard deviations.
To find the probability of a zebra living less than 32.2 years, we first calculate how many standard deviations away from the mean this is, which is called the z-score.
The difference between 32.2 and the mean is 32.2 - 20.5 = 11.7 years.
Dividing this by the standard deviation of 3.9 years, we get a z-score of approximately 3, indicating that 32.2 years is three standard deviations above the mean.
According to the empirical rule, the probability of a zebra living less than 32.2 years would include almost all of the distribution or approximately 99.7%.
Therefore, the probability of a zebra living less than 32.2 years is very high, close to 100%.

Using the number line below find the
probability, as a decimal to the nearest
hundredth, that a point on HP lies between L
and K.
Answer:
0.3
Step-by-step explanation:
To find this probability, we need to know the distance from point H to P and the distance from point L to K, and then the probability of a random point in HP being inside LK will be the division of the distance from L to K by the distance from H to P:
H to P: distance = 15 - 5 = 10
L to K: distance = 10 - 7 = 3
Probability: LK/HP = 3/10 = 0.3
3. A savings account is started with an initial deposit of $500. The account earns 1.5% interest compounded
annually.
(a) Write an equation to represent the amount of money in the account as a function of time in yea
(b) Find the amount of time it takes for the account balance to reach $800.
The equation for the amount in a savings account over time is provided, and the time to reach a balance of $800 is calculated.
The equation representing the amount of money in the account over time is A(t) = [tex]500(1 + 0.015)^t[/tex] where t is the number of years.
To find the time it takes for the account balance to reach $800, we substitute $800 for A(t) in the equation and solve for t.
For $800 = [tex]500(1 + 0.015)^t[/tex], solving for t gives t = 7.31 years.

A lunch menu consists of 4 different kinds of sandwiches, 5 different kinds
of soup, and 3 different drinks. How many choices are there of ordering a
sandwich, soup and drink?
Answer:
4 sandwich + 5 soup +3 drink
total = 20
choices of ordering a sandy , soup and drink =
3/12= 1/4
Final answer:
To determine the number of meal combinations, multiply the number of sandwich, soup, and drink options together. With 4 sandwiches, 5 soups, and 3 drinks, there are 60 different meal combinations.
Explanation:
The student's question is asking for the number of different combinations available when choosing one sandwich, one soup, and one drink from a menu with multiple options for each category. To calculate the total number of combinations, we apply the Fundamental Principles of Counting and use the Multiplication Principle. Since there are 4 kinds of sandwiches, 5 kinds of soup, and 3 drinks, the number of unique combinations can be found by multiplying these numbers together.
Number of combinations = Sandwich options × Soup options × Drink options
= 4 × 5 × 3
The calculation gives us 4 × 5 × 3 = 60 different combinations.

a single point (a vertex of the cube)
a line segment (an edge of the cube)
a triangle (if three adjacent faces of the cube are intersected)
a parallelogram (if two pairs of opposite faces are intersected – this includes a rhombus or rectangle)
a trapezium (if two pairs of
a pentagon (if the plane meets all but one face of the cube)
a hexagon (if the plane meets all faces of the cube)
a pentagon (if the plane meets all but one face of the cube)
a hexagon (if the plane meets all faces of the cube)
The last five of these (the non-degenerate cases)
In a way we can get all the given shapes as a cross-section of a cube, the correct option is D
What is cross-section?A cross-section is the intersection of a plane in an object giving some specific shapes.
Given are the names of shapes, we need to identify we can be the possible shape for the cross-sections of a cube.

O B. (22.5, 2.5)
O c. (25,0)
Answer: (25,0) aka. C
Answer:
c. (25,0)
Step-by-step explanation:
Hope this helps!
The maximum profit is achieved at (25, 0), which means Sal should sell 25 shorts and 0 T-shirts to maximize his profit. So, the answer is (C) (25, 0).
What is profit?Profit is simply the difference between total revenue and total expenses. It shows you how much money your company made after expenses.
Profit, as the primary goal of any business, is a clear indicator of how your company is functioning and performing in the market.
To maximize the profit, we need to use the objective function, which is given by:
P = 14s + 6t
Where s is the number of shorts sold and t is the number of T-shirts sold.
The constraints are:
s + t ≤ 30 (constraint on the total number of items sold)
2s + 5t ≤ 75 (constraint on the amount of shelf space)
The feasible region is the shaded area above.
We can now evaluate the objective function at each corner point of the feasible region to find the maximum profit:
At (0, 20), P = 6(20) = 120
At (7.5, 7.5), P = 14(7.5) + 6(7.5) = 165
At (15, 15), P = 14(15) = 210
At (20, 5), P = 14(20) + 6(5) = 290
At (25, 0), P = 14(25) = 350
Therefore, the answer is (C) (25, 0).
