Answer:
I suppose we want to find the side length of the square.
We know that:
The area of the square is 49cm^2
The distance between one of the vertices of the square and the middle of the square is:
BE = 4.95cm
Now let's remember some things.
For a square of side length L, the area is:
A = L^2
and the diagonal length is:
D = √(2)*L
In this case, we know that half of the diagonal is equal to:
BE = 4.95 cm
Then the diagonal is:
D = 2*BE = 2*4.95cm = 9.9cm
And for the diagonal formula, we have:
D = 9.9cm = √(2)*L
Then the side length is:
L = 9.9cm/√(2) = 7cm
And if we check the area of this square, is:
A = L^2 = (7cm)^2 = 49cm^2
So it checks.
Then we can conclude that the sidelength of the square is 7cm, which means that:
AB = 7cm
BC = 7cm
CD = 7cm
DA = 7cm
Marcos sells snow cones in the summer. He uses a cone with a radius of 1.5 inches and a height of 5 inches. If he fills the snow cone to the rim with ice before pouring on the syrup. About how much ice will it take to fill the cone?
Answer: [tex]11.78\ in.^3[/tex]
Step-by-step explanation:
Given
Radius of cone [tex]r=1.5\ in.[/tex]
Height of cone [tex]h=5\ in.[/tex]
Ice required to fill the cone=Volume of cone
The volume of a cone is
[tex]V=\dfrac{1}{3}\pi r^2h[/tex]
Put values
[tex]\Rightarrow V=\dfrac{1}{3}\times \dfrac{22}{7}\times 1.5^2\times 5=11.78\ in.^3[/tex]

for triangle FGH, angles F and G are known, as is the length of side h. Which method should be used to start solving triangle FGH?
- neither law can be used
- law of sines
- law of cosines
- both laws can be used
Answer:
Law of sines
Step-by-step explanation:
i took the test
The law of sines can be used to calculate the side h. Hence, option B is correct.
What is trigonometry?The branch of mathematics sets up a relationship between the sides and the angles of the right-angle triangle termed trigonometry.
For triangle FGH, angles F and G are known, as is the length of side h. The sin angle is the ratio of the perpendicular to the hypotenuse we can calculate one side by using the sine angle.
Hence, Hence, option B is correct.

Answer:
45°Step-by-step explanation:
The triangle is right isosceles.
It is right as the side is the diameter of the circle.
It is isosceles as two sides marked as equal.
Acute angles are same and equal to:
90°/2 = 45°Correct option is 45°
Answer:
<M=90°[inscribed angle on diameter is 90°]
<N=<L=[base angle of isosceles triangle]
now
<M+<l+<N=180°[sum of interior angle of traingle]
[2x-5]×2=180-90
4x-10=90
x=100/4=25

What is the length of a day-night cycle? Is it the same everywhere on Earth?
12 hours - yes; because the sun rises and sets in the exact same place every day
relative to Earth.
12 hours - no; because depending on where you are on Earth, you have a
different amount of sunlight.
24 hours - yes; because the sun rises and sets in the exact same place every day
relative to Earth
24 hours - no; because depending on where you are on Earth, you have a
different amount of sunlight.
Answer: 24 hours - no; because depending on where you are on Earth, you have a different amount of sunlight.
Step-by-step explanation:
The day-night cycle is a complete day or a complete rotation of the earth around its axis. This takes 24 hours which is why 24 hours is the length of a full day.
People around the world however, do not get the same amount of sunlight or darkness and this is because of where they are on Earth. Due to the way the planet is tilted on its axis, some areas see sunlight more than other in a period and others see more darkness.

On the main floor of the Kodak Hall at the Eastman Theater, the number of seats per row increases at a constant rate. Lucas counts 31 seats in row 3 and 37 seats in row 6. How many seats are there in row 20?
67
61
63
65
Answer:
67
Step-by-step explanation:
There are 65 seats in row 20, option D is correct.
Given that number of seats in row 3 are 31.
Number of seats in row 6 are 37
We need to find the rate of increase, we can calculate the difference in the number of seats between row 6 and row 3 and divide it by the number of rows in between:
Rate of increase = (Number of seats in row 6 - Number of seats in row 3) / (6 - 3)
Rate of increase = (37 - 31) / (6 - 3)
Rate of increase = 2
So, the number of seats increases by 2 seats per row.
To find the number of seats in row 20, we can use the rate of increase:
Number of seats in row 20 = Number of seats in row 3 + (Rate of increase × (20 - 3))
Number of seats in row 20 = 31 + (2× (20 - 3))
= 31 + (2 × 17)
= 31 + 34
= 65
Therefore, there are 65 seats in row 20.
