This diagram shows three small squares and two rectangles composed of 10 small squares.
Diagram of 3 small squares and two rectangles composed of 10 small squares.
a. Jada says this diagram can represent 230. What does a small square represent for Jada?
The small squares represent 30 (each one is equal to 10) if the 2 rows of squares represent 200, if the two rows of 10 squares only represent 20 becuase 10+10=20 then the squares equal 210 (each square equals 70)
Answer:
It is ten

Letter C, E, and F: 2 8/10, 2.8, and 28/10
Step-by-step explanation: The shaded pillars/rectangles inside the squares account for the fractions. In this question, there are 10 pillars per square and 2 shaded in squares. Since there are two full squares, there are two wholes. In the third block, there are only 8 shaded. Because 8 out of ten are shaded, the fraction would be 8/10 (said as eight tenths). Overall, there are two wholes (the shaded squares) and 8/10 of a whole. Therefore, it is 2 8/10. 0.8 equals 8/10 (you can determine it by the way it is said ex: you would say “zero and ...” (and = decimal) “... eight tenths” or just “eight tenths” for .8, and 8/10 is said the same way). Since 2.8 and 2 8/10 are equal, 2.8 would also be an answer. 28/10 would be another correct answer because the two wholes/squares each have 10 pillars. In total, there are 20 pillars for the two wholes. If the 8/10 (8 out of 10) is added, the total would be 28/10. Hope this helps!

Using the Pythagorean Theorem, fill in the table. [Assume a and b are the lengths of the legs and c is the length of the hypotenuse.]

[ Select ]
7
[ Select ]
25
[ Select ]
30
34
9 40
[ Select ]
Answer: It would be Second leg = 15
Step-by-step explanation:
From my understanding, you are supposed to find the second leg of the right triangle by Pythagoras theorem.
Hypotenuse: 25
One leg: 20
Second leg: x
Pythagoras theorem: hypotenuse² = adjacent² + opposite²
c² = a² + b²
25² = 20² + b²
b² = 25² - 20²
b² = 625 - 400
b² = 225
b = √225
b = 15
Therefore, the second leg of the right triangle is 15.

Find the median of this set of data: 3, 8, 9, 2, 4, 7, 2
Answer:
2
Step-by-step explanation:
the midian is the middle
Given : 2, 3, 8, 9, 2, 4, 7, 2 .
To Find: Median of data .
Solution : Firstly arranging the data in ascending order we get , 2 , 2 , 3 , 4 , 7 , 8 , 9 . Here number of terms = 7 .
So the median will be the middlemost value.
Here the middle most value is 4 .
Therefore the median is 4 .
Find the value of x and find whether the angles or supplementary or complementary.
Answer:
Both angles add up to 90° so they are complementary angles, x = 55
Step-by-step explanation:
=> We know that both angles add to 90°, so the equation will be;
(x - 20) + (x) = 90
=> Using algebra if solved all the way down, "x" will be 55.

Answer:
Both -1.5 and -3/2 will be halfway between -2 and -1 on the number line. 3/2 will be halfway between 1 and 2. -4/3 will be between -1.5 and -1.
Answer:
Well I can’t really do anything, the best thing I can tell you is that for each number, look at each option and Plot it from there.
You can turn all these into decimals since the number line is a whole number line and decimals are easier to work with in this situation then fractions. So you would have
-1.5, 1.5, -1.5, and -1.33333...
So -1.5 and -3/2 are the same so thats one plot, that would go between -1 and -2.
1.5 goes between 1 and 2
And -1.333...goes more closer to -1 between -2 and -1
A box is to be made where the material for the sides and the lid cost $0.20 per square foot and the cost for the bottom is $0.05 per square foot. Find the dimensions of a box with volume 20 cubic feet that has minimum cost.
Please answer in length , width and height in ft
Answer:
Let x represent the edge dimension of the square base in feet. Then the area of the base or lid is x², and the height of the box is 5/x². Total cost is then ...
... cost = cost of lid + 4×(cost of one side) + cost of bottom
... cost = 0.2x² + 4×(0.2x(5/x²)) + 0.5x²
... cost = 0.7x² + 4/x
We can differentiate this with respect to x and set that derivative to zero. This will give us the x-value at which the cost is a minimum.
... d(cost)/dx = 1.4x -4/x² = 0
... x³ = 4/1.4
... x = ∛(20/7) ≈ 1.419
Then the height of the box is
... height = 5/x² ≈ 5/2.01351 ≈ 2.483
The box is 1.491 ft square and 2.483 ft high.
______
The average cost of the top and bottom is (0.2 +0.5)/2 = 0.35 per square foot. The overall cost will be minimized when the average cost of each face is the same. That is, the areas of the lateral faces will be equal and must be 0.35/0.2 = 1.75 times the area of the top or bottom to make the average cost of a lateral face equal to that of the top or bottom. Hence, the base will be square, and the box will be 1.75 times as high as it is wide or deep. The base edge dimension is then ∛(5/1.75) ≈ 1.419 ft.
