Answer:
A=25√3 cm^2
Step-by-step explanation:
Since it is a regular triangle, all sides are equal to 10cm. The dotted line is a perpendicular bisector, which means that it seperates the triangle into two perfect halves. So a right triangle is formed. The bottom of the right triangle will be half of 10, and 10/2=5. So to find the missing side, use the pythagoreom theorem.
5^2+x^2=10^2
25+x^2=100
x^2=75
x= 5√3
The height of the triangle is found, so apply the formula for area:
A=1/2*5√3*10
A=25√3

Tatum walks her dog 2/3 mile every day after school. How many miles does she walk her dog in 5 days
Answers
The number of miles that Tatutm walk her dog in 5 days is given by: Option B: 10/3 (in miles)
How to add two fractions?Let we have to add two fractions as:
[tex]\dfrac{a_1}{b_1} + \dfrac{a_2}{b_2}[/tex]
Then we will find Lowest Common Multiple (LCM) of [tex]b_1[/tex] and [tex]b_2[/tex]. That will help to make the denominators same.
Once the denominators become same, the numerators can add up directly, giving us the final result of addition.
For this case, we're given that:
Each day, Tatum walks her dog 2/3 milesFor 5 days, the total distance her dog walked = 2/3 + 2/3 + 2/3 + 2/3 + 2/3
Since denominators are same, thus:
[tex]\dfrac{2}{3} + \dfrac{2}{3} + \dfrac{2}{3} + \dfrac{2}{3} + \dfrac{2}{3} = \dfrac{2+2+2+2+2}{3} = \dfrac{10}{3}[/tex]
We could've easily done it as: 2/3 + 2/3 + 2/3 + 2/3 + 2/3 = 5 times 2/3 = [tex]5 \times \dfrac{2}{3} = \dfrac{5 \times 2}{3} = \dfrac{10}{3}[/tex]
Thus, the number of miles that Tatutm walk her dog in 5 days is given by: Option B: 10/3 (in miles)

55% of the total books are non-fiction.
Step-by-step explanation:
There are a total of 80 books, and there are 44 non-fiction books among them.

(44/80) × 100 = 55%
Check if (1,6) is the solution to the system shown below.
Answers
Answer:
NO it is not
Step-by-step explanation:
To check that, we will need to substitute the value of each of the coordinates in each of the equations
10x-y = -6
substitute 1 for x and 6 for y
we have this as;
10(1)-6 = 4
Outrightly, we can see that the given point is not a solution to the given system of equations
however, let us confirm for the second
We have this as;
-10(1) + 5(6)
= -10 + 30 = 20
so we can confirm that it does not work for any of the two and our answer is NO

Answer:
10218.75
Step-by-step explanation:
You should divide the two shapes into a rectangle and a triangle, find the area of each, then add them together like so:
For the rectangle:
37.5*22.5 = 843.75
For the triangle:
To find the base: 75 - 37.5 = 37.5
To find the height, use pythagoream theorem.
62.5² = 37.5² + b²
3906.25 = 1406.25 + b²
3906.25 - 1406.25 = 2500
√2500 = 50.
The height is 50, so 50*37.5(1/2)
= 937.5
Now add them together
937.5 + 843.75

Answers
Answer:
You are correct that the cross section is a rectangle, because a rectangular pyramid has 4 sides connected to the top of the rectangle.
Step-by-step explanation:
We can estimate that the probability of making 3 or more kicks in a game is approximately 0.8 or 80%.
What is simulation?Simulation is the process of creating a computer model or a physical system that behaves like a real-world system or process, in order to study its behavior or performance under various conditions.
We have,
To estimate the probability that 3 or more kicks are made, we need to count the number of trials in which 3, 4, or 5 kicks were made, and divide that by the total number of trials (which is 5 in this case).
From the table,
We can see that there are three trials in which 3 kicks were made
(trials 1, 3, and 5), one trial in which 4 kicks were made (trial 4), and no trials in which all 5 kicks were made.
The total number of trials in which 3 or more kicks were made is:
= 3 + 1 + 0
= 4
To estimate the probability, we divide the number of successful trials by the total number of trials:
P(3 or more kicks made) ≈ 4/5
Therefore,
We can estimate that the probability of making 3 or more kicks in a game is approximately 0.8 or 80%.
