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!
A block of iron has dimensions of 1 cm x 2 cm x 5 cm and has a
mass of 799
What is its density? (V=lxwxh)
Answer:
79.9 units
Step-by-step explanation:
Hi there,
Before solving this problem, it is important to know the formula:
D = [tex]\frac{m}{v}[/tex].
D = density
m = mass
v = volume
Since we are given the mass and volume, we can simply enter these values into the formula to find the density of the block.
D = [tex]\frac{799}{10}[/tex]
D = 79.9
Therefore, the density of the block of iron is 79.9 units. I wrote units since you did not specify the unit for the mass. Hope this answer and explanation helps.
Cheers.

Ella and Jake love to skateboard. They created a frame for the ramp and then covered it with wood.
How much wood did it take to cover the ramp, including the bottom?
Give an exact answer (do not round).
Answer:
triangle side = 0.54
so both triangle sides = 1.08
and then the sides (1.5 * 3.5) * 2 = 10.5
the last side = 0.9 * 3.5 = 3.15
so add it all 3.15 + 10.5 + 1.08
total area = 14.73 m^2

Given: circle k(O), diameter US, measure of arc RU=50, measure of arc UT=30
Find: measure of angle RUS and measure of angle UST
Answer:
angle RUS = 65 degrees
angle STU = 90 degrees
Step-by-step explanation:
(a) find angle RUS
Given arc RU = 50 degrees, so angle RSU = 50/2 = 25 degrees
Since US is the diameter,
angle URS is a right-angle.
Consider triangle RUS,
sum of angles of a triangle = 25+90+RUS = 180
solve for
RUS = 180 - 25 - 90 = 65 degrees.
(b) Find STU
All diameters span a right angle at the circumference,
since we're given US is a diameter, this means that
angle STU is a right angle.
The measure of the ∠RUS is 65°, while the measure of ∠UST is 15°.
What is Thales theorem?The angle ABC is a right angle if A, B, and C are different points on a circle where the line AC is a diameter, according to Thales' theorem.
We know that when an angle is made by the diameter of a circle at its circumference, then the measure of that angle is 90°.
In ΔUST,
The angle made by the diameter is ∠UST, therefore, the measure of this angle will be 90°. Since the measure of the arcRU=50°, therefore,
arcRU = ∠ROU = 50°, Also,
[tex]\angle RSU=\dfrac{\angle ROU}2 =\dfrac{50^o}2 = 25^o[/tex]
Now, the sum of the angles of a triangle is 180°.
∠R+∠U+∠S=180°
90°+∠RUS+25°=180°
∠RUS = 65°
In ΔRUS,
The angle made by the diameter is ∠URS, therefore, the measure of this angle will be 90°. Since the measure of the arcUT=30°, therefore,
arcUT = ∠UOT = 30°, Also,
[tex]\angle UST=\dfrac{\angle UOT}2 =\dfrac{30^o}2 = 15^o[/tex]
Thus, the measure of the ∠RUS is 65°, while the measure of ∠UST is 15°.

I believe the answer is B.
Step-by-step explanation:
The questions says for every 1 hour she reads a book, she reads 0.25 hours with a magazine. Answer B says 2 hours for book, meaning that you wouldn’t have 0.25, you would have 0.5. So for books, you’d go up every 2 hours, and for magazines, you’d continue going up in half’s!

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.
