Answer:
12 babies4 adultsStep-by-step explanation:
Let x represent the number of adult dinosaurs. Then 3x is the number of babies. The total number of paintings is ...
15(3x) +7(x) = 208
52x = 208 . . . . . . . . . simplify
x = 4 . . . . . . . . . . . divide by 52
3x = 4·3 = 12
There were 12 baby dinosaurs and 4 adult dinosaurs.

greater than 2 but less than 3
greater than 3
Use pencil and paper. Explain the reasoning behind your choice.
Question content area bottom
Part 1
275% of 40 is :
Answer: 110
Step-by-step explanation: Write 275% as
275
100
Since, finding the fraction of a number is same as multiplying the fraction with the number, we have
275
100
of 40 =
275
100
× 40
Therefore, the answer is 110
If you are using a calculator, simply enter 275÷100×40 which will give you 110 as the answer.

P to Q: greater than 1P to R: greater than 1Q to S: less than 1Q to R: greater than 1S to P: equal to 1R to P: less than 1P to S: equal to 1========================================================
Explanation:
We have these three rules for scale factors
scale factor > 1, enlarge the image0 < scale factor < 1, shrink the imagescale factor = 1, the preimage and image are identicalWith those rules in mind, we have enlargements for these transformations.
P to QP to RQ to RAll of which represent some scale factor larger than 1. We don't have enough information to pinpoint what that scale factor would be.
In other words, if you go from small to big, then you apply some scale factor larger than 1 to enlarge the image.
----------------
We also have these reductions
Q to SR to PThis is where we go from big to small. The image shrinks and we use some scale factor between 0 and 1.
----------------
And finally we have these transformations in which the size of the image does not change. Therefore the scale factor is 1.
P to SS to PThe order doesn't matter for this subset, but the order will matter for the other batches of transformations.

Use the Midpoint Rule with \(n=5\) to estimate the volume obtained by rotating about the y-axis the region under the curve \(y=\sqrt{1+x^3}\), \(0\leq x\leq 1\).
To estimate the volume using the Midpoint Rule with \(\displaystyle n=5\), we need to divide the interval \(\displaystyle 0\leq x\leq 1\) into \(\displaystyle n\) subintervals of equal width. Since \(\displaystyle n=5\), each subinterval will have a width of \(\displaystyle \Delta x=\frac{1-0}{5}=\frac{1}{5}\).
Now, let's calculate the volume using the Midpoint Rule. The formula for the volume obtained by rotating about the y-axis is:
\(\displaystyle V\approx 2\pi \sum _{i=1}^{n}y_{i}\Delta x\)
where \(\displaystyle y_{i}\) represents the value of the function \(\displaystyle y=\sqrt{1+x^{3}}\) evaluated at the midpoint of each subinterval.
First, let's find the midpoints of the subintervals. Since the width of each subinterval is \(\displaystyle \Delta x=\frac{1}{5}\), the midpoint of the \(\displaystyle i\)-th subinterval is given by:
\(\displaystyle x_{i}=\frac{\Delta x}{2}+\left( i-\frac{1}{2}\right) \Delta x=\frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\)
Substituting \(\displaystyle x_{i}\) into the function \(\displaystyle y=\sqrt{1+x^{3}}\), we obtain:
\(\displaystyle y_{i}=\sqrt{1+\left( \frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\right) ^{3}}\)
Now, we can calculate the approximate volume using the Midpoint Rule:
\(\displaystyle V\approx 2\pi \sum _{i=1}^{5}y_{i}\Delta x\)
Substituting the values of \(\displaystyle y_{i}\) and \(\displaystyle \Delta x\) into the formula, we can evaluate the sum and compute the estimated volume.

Data was collected on the weight, in ounces, of kittens for the first three months after birth.
A line of fit was drawn through the scatter plot and had the equation w = 3.25 + 0.3d, where w is the weight of the kitten in ounces and d is the age of the kitten in days.
What is the w-intercept of the line of fit and its meaning in terms of the scenario?
3.25; a kitten who is just born is predicted to weigh 3.25 ounces
0.3; a kitten who is just born is predicted to weigh 0.3 ounces
3.25; for each additional day after the kitten is born, its weight is predicted to increase by 3.25 ounces
0.3; for each additional day after the kitten is born, its weight is predicted to increase by 0.3 ounces
Answer:
A. 3.25
Step-by-step explanation:
A kitten who is just born is predicted to weigh 3.25 ounces and its weight is predicted to increase by 0.3 ounces. Then the correct option is A,D.
1. The 0.3d is the day each day
So
==> 0.3d +3.25(the first day born) ==> w ( means the d is the day so it increase 0.3 per day)
What is a linear equation?
A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
y = mx + cWhere m is the slope of the line and c is the y-intercept of the line.
Information was gathered on the weight, in ounces, of cats for the initial three months after birth. A line of fit was drawn through the dispersed plot and had the condition w = 3.25 + 0.3d, where w is the heaviness of the cat in ounces and d is the age of the little cat in days.
A kitten who is just born is predicted to weigh 3.25 ounces and its weight is predicted to increase by 0.3 ounces. Then the correct option is A.

On a certain hot summer day, 481 people used the public swimming pool. The daily prices are $1.25 for children and $2.25 for adults. The receipts for admission totaled $865.25. How many children and how many adults swam at the public pool that day?
Answer:
264 Adults & 217 Children
Step-by-step explanation:
children = c
adults = a
a + c = 481...(Equation 1)
1.25c + 2.25a = 865.25...(Equation 2)
Equation 1 can also be written as,
a = 481 - c
Now we can substitute the value of 'a' in Equation 2
1.25c + 2.25 (481 - c) = 865.25
1.25 c + 1082.25 - 2.25c = 865.25
-c = 865.25 - 1082.25
-c = -217
c = 217
Now, we can substitute the value of 'c' in Equation 1
a + c = 481
a + 217 = 481
a = 481 - 217
a = 264

Rasheem runs 1/5 miles in 2 minutes.
What is Rasheem’s speed in miles per minute?
Explain if you can. :)
Answer:
10 minutes per mile
Step-by-step explanation:
Rasheem runs 1/5 miles in 2 minutes. What you need to do is find how many minutes it takes for 1 whole mile. To do this, you have to first see what you multiply to 1/5 to get to 1. As you know, you do 1/5 x 5/1 (or 5) to get to one. Since you did that 1/5, you also need to multiply 2 x 5, which is 10. This gives you the answer that Rasheem was running 10 minutes per mile.
Hope it helped! :)

Use the diagram of the equilateral triangle shown below to answer the following questions. Show the work that leads to your answers. a. What is the perimeter of the triangle? b. What is the height, ℎ mm, of the equilateral triangle? Write an exact answer using a square root and an approximate answer rounded to the tenths place.
Answer:
Perimeter is 12mm, height is \(2\sqrt3\)mm in simplest radical form, and 3.5mm in approximate decimal form.
Step-by-step explanation:
The perimeter is easy; since it's an equilateral triangle, all sides are the same length of 4, so you can just do 3*4 (3 sides, 4mm each) to get a perimeter of 12.
For the height, you can see that it forms two right triangles, each with a given base of 2 and a hypotenuse of 4. We can apply the pythagorean theorem (\(a^2+b^2=c^2\)) here to find the missing leg length of the smaller right triangles, which is equal to the big triangle's height.
I've enclosed an attachment for that.

You randomly choose one of the tiles and flip the coin. Find the probability of the compound event. Write your answer as a fraction or percent rounded to the nearest tenth.
8 tiles
Answer:
Step-by-step explanation:
3/7 x 1/6 = 1/14 is the probability of choosing an odd and then the 20
3 ways to get odd out of 7 possibilities. 1 way to get 20 out of 6 remaining tiles.
Multiply the probabilities to get the compound probability.
Or if you wanted 20 and then an odd, it's
1/7 x 3/6 which also = 1/14
