Which model represents the product 3×25? (Giving brainliest.)
I think that is the answer because it says 2/5 where two rows are shaded and three more rows remain unshaded so, when you add that three and two it's altogether 5, so I think that is the answer, please check out the document I have uploaded.
Answer:
the one you are currently clicking on (you're correct :) )
Step-by-step explanation:
For the item you are currently clicking on, there are three columns--each with five rectangular sections. Each of the three columns--as we can see on the label to the left, is equal to 1. So, the five split pieces must all combine to stack up to 1. This means that 1 must be divided amongst 5 pieces, so we divide 1 by 5: 1/5.
You are trying to find the model that represents 2/5 (times 3, so it will have three rows). For the model you are clicking on, each column is showing two rectangles being there. This means that you have two sections of 1/th--or, 2/5ths present.
This means that you have the fraction of 2/5th, and you have it three times, so it represents three 2/5ths fractions, or 3 x 2/5.
(Remember, multiplication is repeated addition. So, 3 times of something means that its there 3 times, you have three 2/5ths)
In analyzing statistical data, which do you think is more likely: a correlation coefficient of 0.9 or a correlation coefficient of 1.0? Explain.
Imagine that you have plotted many data points on an xy-plane. Your points seem to align into a clear best-fit line. Do you think this best-fit line can help you make predictions about future data? Explain your answer, and give one or more examples to support it.
You're studying how well students remember vocabulary after they stop studying a new language. The first student you study remembers 95% of the French words she learned 3 months later, but only 70% of the words 12 months later.
Before studying more students, you wonder: Is a decreasing linear model or an exponential decay model likely to be a better fit for data about remembering? Decide which model you think will be better. Explain your reasoning.

Answer:
1,256 dm^2 and 400π dm^2
Step-by-step explanation:
The circumference is equal to 2pi times the radius. So 40pi=2pi times the radius so the radius is 20. The area of a circle is pi times the radius squared or 400pi and if using 3.14 for pi this would be 1,256 dm^2

Hugh bought some magazines that cost $3.95 each and some books that cost $8.95 each. He spent a total of $47.65. If Hugh bought 3 magazines, how many books did he buy?
The equation that models the problem is 3.95m + 8.95b = 47.65, where m is the number of magazines and b is the number of books.
__ books
Answer:
4 books
Step-by-step explanation:
Our problem here is:
[tex](3.95)3+8.95b=47.65[/tex]
So we have to find B, and that will be our answer (the number of books).
1. Simplify the expression
[tex]3.95\cdot 3+8.95x=47.65[/tex]
Combine like terms:
[tex]11.85+8.95x=47.65[/tex]
2. Group all constants on the right side of the equation
[tex]11.85+8.95x=47.65[/tex]
Subtract from both sides:
[tex]11.85+8.95x-11.85=47.65-11.85[/tex]
Group like terms:
[tex]8.95x+11.85-11.85=47.65-11.85[/tex]
Simplify the arithmetic:
[tex]8.95x=47.65-11.85[/tex]
Simplify the arithmetic:
[tex]8.95x=35.8[/tex]
3. Isolate the x
[tex]8.95x=35.8[/tex]
Divide both sides by 8.95:
[tex]\frac{8.95x}{8.95}=\frac{35.8}{8.95}[/tex]
Simplify the arithmetic:
[tex]x=\frac{35.8}{8.95}[/tex]
Simplify the arithmetic:
[tex]x=4[/tex]
Hence, the number of books is 4What is that answer to 6 (3/8) - 5 (5/8) ?
Answer:
[tex]-\frac{7}{8}[/tex]
Step-by-step explanation:
1) Use this rule: [tex]a \times \frac{b}{c} =\frac{ab}{c} .[/tex]
[tex]\frac{6\times3}{8} -5\times\frac{5}{8}[/tex]
2) Simplify 6 × 3 to 18.
[tex]\frac{18}{8} -5\times\frac{5}8}[/tex]
3) Simplify [tex]\frac{18}{8}[/tex] to [tex]\frac{9}{4}[/tex].
[tex]\frac{9}{4} -5\times\frac{5}{8}[/tex]
4) Use this rule: [tex]a\times\frac{b}{c}=\frac{ab}{c} .[/tex]
[tex]\frac{9}{4} -\frac{5\times5}{8}[/tex]
5) Simplify 5 × 5 to 25.
[tex]\frac{9}{4} -\frac{25}{8}[/tex]
6) Simplify.
[tex]-\frac{7}{8}[/tex]

CIRCLE THEOREM QUESTION ------> PLEASE HELP WITH THIS!
I REALLY NEED YOUR HELP!
Answer:
e = 126
Step-by-step explanation:
Both triangles are isosceles triangles. Therefore in the smaller triangle, there are two angles that are equal to 42 degrees (the other one is next to e)
42 + 42 = 84
there are 180 degrees in a triangle
180 - 84 = 96
So the last angle in the triangle (The little one) is equal to 96 degrees.
The rule for cyclic quadrilaterals is that the two opposite angles equal 180. So the angle opposite 96 degrees will be equal to:
180 - 96 = 84
As the larger triangle is also an isosceles (as mentioned above), two angles will be equal to each other. The two angles that are equal are at the bottom left. As one of them is equal to 84, the other is also equal to 84. This means the last angle (the one at the top) is equal to:
180 - (84 + 84) =
180 - 168 = 12
Angles on a straight line always equal 180 degrees. So 'e' is equal to 180 minus the other two triangle angles on the line they all share.
180 - (12 + 42) =
180 - 54 = 126
Therefore e = 126

Help. Where do I put the dot, should it be opened or closed, and what direction should the line face?
Answer: 5 with an open circle facing the right.
Step-by-step explanation:
First: you need to know the difference between closed and open circles. Closed means less than or equal to/ greater than or equal to while an open circle just means less than/ greater than.
Second: To know if it will be facing left or right is very simple. It is just if the number is increasing or decreasing in your problem. If increasing it goes right if decreasing it goes left. In this case, the number increases each day so it will face the right.
Third: To start the problem you subtract the number of shells she has already (34) by how many she needs (100) which is 66. then divide 66 by the number of seashells they get a day (12) which would give you 5.5
Fourth: I'm going to guess that you can't do decimals on the graph so all you have to do is put an open circle with the arrow facing the right meaning everything after this point, not including the number it is on.
Answer:
d ≥ 7
Step-by-step explanation:
A closed dot means you CAN use the number in the equality (greater than and equal to or less than and equal to). An OPEN dot means it's just greater than or less than, no equal to. Positive numbers GROW to the right so if the line is going that way it means greater than or greater than and equal to. The same is true for the left side. The left side makes numbers get SMALLER which means less than or less than and equal to. Your problem has a closed dot and an arrow to the right so the inequality is d ≥ 7.

Which expression represents a number that is 4 times as great as the quotient of 25 and 5?
A. (25 × 5 ) × 4
B. 4 ÷( 25 × 5)
C. 4 X ( 25 ÷ 5 )
D. ( 25 ÷ 5 ) ÷ 4
Answer:
C. 4 × ( 25 ÷ 5 )
Step-by-step explanation:
The wording "the quotient of A and B" means A÷B. A value is 4 times as great if it is multiplied by 4.
__
The quotient of 25 and 5 is (25 ÷ 5).
The expression that represents a value 4 times as great is this quotient multiplied by 4:
4 × (25 ÷ 5)

I need help with this and I've looked for websites for help, no luck. Please help
Answer:
1 1/27 = 28/27
Step-by-step explanation:
First you evaluate your parenthesis, and to do that you need to find the Least Common Denominator of 2/3 and 2/9. The least common denominator would be 9. 3 x 3 = 9 so you multiply 2 x 3 = 6. 6/9 - 2/9 = 4/9. 7/3 x 4/9
7 x 4 = 28
3 x 9 = 27
28/27 = 1 1/27
Hey there!
7/3 * (2/3 - 2/9)
= 7/3 * 4/9
= 7(4) / 3(9)
= 28 / 27
≈ 1 1/27
Therefore, the answer should be:
28 / 27
OR
1 1/27
Either should work because they are both equivalent to each other.
Good luck on your assignment & enjoy your day!

The contents of two boxes are shown below. What is the probability of drawing a vowel from box 1 and an even number from box 2?
Box 1: A, B, C, D, E
Box 2: 1, 2, 3, 4, 5, 6, 7, 8, 9
PLEASE SHOW ALL YOUR WORK AND GET 30 POINTS !!!!!!! THANK YOU
Answer:
vowel = 2/5
even number = 4/9
Step-by-step explanation:
vowel:
total of all letters in the box= 5
cound total number of vowels in the box = 2
[tex]\frac{2}{5}[/tex] because out of the 5 letters there is 2 vowels so overall you have a [tex]\frac{2}{5}[/tex]chance of pulling out a vowel.
Same logic for the even numbers one.
Even numbers:
total amount of numbers in the box: 9
total amout of even numbers: 4
[tex]\frac{4}{9}[/tex] because you have 9 numbers in total and you want the chnce of finding an even number. That means you need to put the amout of even numbers on top of the fraction and the total amount below.
OVERALL:
simple way of remembering it is:
p = total amout of the thing you want the probability of finding (in this case even numbers or vowels)
t = total amout of all options in the box (or any container)
[tex]\frac{p}{t}[/tex]

Answer:
[tex]144 in^{2}[/tex]
Step-by-step explanation:
We can see in the figure that you have 4 triangles, all congruent, and 1 square in the middle. The measure of the square is 8x8, so first find the area of that, 64. Then, we only need to find the area of 1 triangle and multiply that by 4, as you have 4 triangles in the figure. The area of a triangle is (base×height)/2 so fill in the values. The base is 8 in, and the height is 5 in. 5×8 is 40, so we divide that by 2 and get 20. Then multiply this by 4, and you get 80. Now, take your original area of the square, and add it to the area of the 4 triangles. 64+80=144
