What is the value of y?
I think the hypotenuse is 8 and if it is, am I supposed to do
C^2 - B^2 = A^2?
Answers
make sure your calculator is in Degree mode.
The angle, 60, is directly opposite with what you're trying to find, y. Also since you have another side of the triangle that is identified, you can figure what trig function to use. The line next to the angle is the adjacent. We have the adjacent and opposite. The trig function that implements both sides is the Tangent. The formula for it is tangent(angle) = opposite/adjacent.
Now substitute the number into the formula.
tan(60) = y / 5
We need to isolate y, so we times 5 and tan(60)
tan(60) x 5 = 8.66
y is now isolated and the answer is 8.66 = y

2. A cube-shaped aquarium has edges that are 3 ft long. The aquarium is filled with water that has a density of 62 lb/ft³.
(a) Should the aquarium be placed on a table that can support a maximum weight of 200 lb? Explain why or why not.
(b) Would the density of the water change if the aquarium was only half full? Explain.
Answers
Let's find the volume of the tank.
Volume of a rectangular prism = length*width*height
V = L*W*H
V = 3*3*3
V = 27 cubic feet
There is 27 cubic feet of water in the tank if the tank is completely full. Use the fact that
1 cubic foot of water = 62 pounds
so we can convert from volume to weight
(27 cubic feet)*(62 pounds/1 cubic foot) = 27*62 = 1674 pounds
If the tank is completely full, then the water weighs 1674 pounds, which is far greater than the 200 lb max weight limit for the table. The table will fall apart if you place a full aquarium on top of it. Note: this is not including anything else that would go inside the tank such as rocks, plant matter, fish, the glass of the tank itself, etc
In short, the aquarium should not be placed on the table as it exceeds the table's weight limit.
---------------------------------------------------------------------------
Part (b)
The density will not change because the density is how packed in a substance is for any cubic unit of volume. Saying "the density of water is 62 pounds per cubic foot" means that for a cubic foot, water naturally weighs 62 pounds .We can scale this to any size we want and the density will stay the same.
It's like saying that the fractions 1/2 and 2/4 are the same. The 2/4 is the scaled version of 1/2. So back to the water example, if we had 2 cubic feet of water then it would weigh 2*62 = 124 pounds. So the ratio
2 cubic feet: 124 pounds
simplifies back to
1 cubic foot: 62 pounds
note: the larger the density, the heavier the object is assuming the volume is held constant
The weight of the water in the cube-shaped aquarium will be 1674 lb, which is much greater than the table's maximum weight capacity of 200 lb. Therefore, the aquarium should not be placed on the table. The density of the water remains constant at 62 lb/ft³ regardless of how much the aquarium is filled.
To determine if the aquarium can be placed on a table with a weight limit of 200 lb, we must first calculate the weight of the water the aquarium will hold. We calculate the volume of the aquarium, then multiply it by the density of water, as the density is given as weight per unit volume (specifically 62 lb/ft³).
The volume (V) of a cube is given by V = side³, so for our aquarium with 3 ft long edges, V = 3³ = 27 ft³. The weight of the water (W) is therefore W = density x volume = 62 lb/ft³ x 27 ft³ = 1674 lb. Since 1674 lb exceeds the table's maximum weight capacity of 200 lb, the aquarium should not be placed on the table.
As for part (b), the density of the water does not change whether the aquarium is full or half full. Density is an intensive property meaning it's independent of the quantity of the substance present. Therefore, whether the aquarium is filled or only half filled, the density of the water remains at 62 lb/ft³.
How many eggs are needed to make 1 dozen waffles, assuming you have enough of all other ingredients? given: 2 cups flour + 3 eggs + 1 tbs oil → 4 waffles
a. 12
b. 48
c. none of these choices is correct
d. 9
e. 16?
Answers
We have been given that
2 cups flour + 3 eggs + 1 tbs oil → 4 waffles
In order to make 4 waffles we need 3 eggs.
Thus, to make 1 waffle we need 3/4 eggs.
Now, in 1 dozen there are 12 waffles. Hence, to make 12 waffles we need
[tex]\frac{3}{4} \times 12\\ \\ =3 \times 3\\ =9[/tex]
Therefore, 9 eggs are needed to make 1 dozen waffles.
D is the correct option.
Final answer:
The correct option is (d) 9. Using the given recipe, we can determine that 9 eggs are needed to make 1 dozen waffles by setting up a proportion and solving for the number of eggs.
Explanation:
The original recipe provided states that 2 cups of flour, 3 eggs, and 1 tablespoon of oil will yield 4 waffles. To find out how many eggs are needed to make 1 dozen (12) waffles, we need to set up a proportion based on the given recipe.
Since 4 waffles require 3 eggs, we can set up the following equation: 4 waffles / 3 eggs = 12 waffles / x eggs. Cross-multiplying gives us 4x = 36, and dividing both sides by 4 gives us x = 9. Therefore, 9 eggs are required to make 1 dozen waffles.

1) If the endpoints of the diameter of a circle are (9, 4) and (5, 2), what is the standard form equation of the circle?
Answers
Midpoint = [tex]( \frac{X1+X2}{2} , \frac{Y1+Y2}{2} )[/tex]
where X1 is the x-coordinate of the first ordered pair and Y1 is the y-coordinate of the first ordered pair. Same applies to X2 and Y2. So now we plug in.
Mdpt = [tex]( \frac{9+5}{2} , \frac{4+2}{2} )[/tex]
= [tex]( \frac{14}{2} , \frac{6}{2} )[/tex]
Your midpoint is at (7, 3).
This gives you the beginning of the equation. The equation of a circle is:
(x - h)² + (y - k)² = radius²
where (h, k) is the center.
Your equation is:
(x - 7)² + (y - 3)² = radius²
To find the radius, we do either the distance formula from the center to either of the endpoints. Or the distance between the two endpoints divided by two. Depends on which one you want to do. I choose the latter, but it's all personal preference.
Distance formula = √((X2 - X1)² + (Y2 - Y1)²)
So we plug in:
D = √((5 - 9)² + (2 - 4)²)
D = √((- 4)² + (- 2)²)
D = √(16 + 4)
D = √20
Distance of the diameter = 2√5
Now divide that by 2, your radius is √5
Now we plug in to the equation:
(x - 7)² + (y - 3)² = (√5)²
Your final equation is:
(x - 7)² + (y - 3)² = 5

There are 750 toothpicks in a regular sized box. If a jumbo box is made by doubling all the dimensions of the regular sized box, how many toothpicks will the jumbo box hold? (With work pls)
Answers
To answer this, let the 3 sides of the regular sized rectangular box be x, y, and z.
When we double all the sides, the new sides have lengths 2x, 2y, and 2z, respectively.
Since the regular box (with dimensions x,y, and z) have 750 toothpicks, we can write
[tex]xyz=750[/tex]
Similarly we can write for the jumbo box as,
[tex](2x)(2y)(2z)[/tex]

We know that center-radius form of a circle is in format: [tex](x-h)^2+(y-k)^2=r^2[/tex], where,

Account balance = $26,292
Return on the investment
Difference = $26,292 - $26,245 = $47
Investment is increase by $47
Now calculate the percentage of rate of return.
Percentage change = ($47 / $26,245) x 100 = 0.2%
Rate of return is 0.2% positive according to given data. Hence proved that, the given rate of return is inconsistent.
