Answer:
Base=40m and
Altitudes=20m
Step-by-step explanation:
Area of the field can be calculated as
Area= total cost / rate
Where total cost= 4,000 rupees
Rate= 10 per m2
Area of the field= 4000/10
= 400m^2
Let the altitudes be denoted as "x metre"
Then the base = 2x
Area= 1/2bh
Where b= base
h= altitudes
Then if we substitute we have
400m^2= 1/2× x × 2x
400= x^2
x= √400
x=20m
Then altitudes = 20m
the base = 2x= 2×20=40m
Hence, it base and altitude are 40m and 20m respectively.
A line AB joins the points A (3,4) and B (5,8). Write down the coordinates of the midpoint of the line AB
Please help
Thank you
Given:
A line AB joins the points A (3,4) and B (5,8).
To find:
The midpoint of the line AB.
Solution:
Midpoint formula:
[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]
A line AB joins the points A (3,4) and B (5,8). So, the midpoint of line AB is
[tex]Midpoint=\left(\dfrac{3+5}{2},\dfrac{4+8}{2}\right)[/tex]
[tex]Midpoint=\left(\dfrac{8}{2},\dfrac{12}{2}\right)[/tex]
[tex]Midpoint=\left(4,6\right)[/tex]
Therefore, the midpoint of the line AB is (4,6).
Pls help :(
Clare and Han are discussing how to find the missing lengths. Clare says she is using similarity. Han says he is using the Pythagorean Theorem.
Find the missing sides
Answer:
similarity
Step-by-step explanation:
look , dude
the two triangles have the following features:
the angle B= angle C = 90 degree
the angle A= the angle F
so the third angle in the first triangle = the third angle in the second triangle
so you have one condition of similarity which is the three angles are equal
to get the answer for lengths :
ab/fe= constant of proportionality
thus ab/fe=2.5/5=.5
so ac/13=.5 thus ac=6.5
and 6/de=.5 so de=12
Both similarity and Pythagorean theorem can be used to find the missing lengths as AC = 6.5 and DE = 12.
What are Similar Triangles?Similar triangles are those triangles which has the same shape but different size.
The length of sides and angles are proportional in similar triangles.
Pythagorean theorem states that for a right angled triangle,
Hypotenuse² = Base² + Altitude²
AC² = BC² + AB²
AC² = 6² + 2.5²
AC² = 42.25
AC = √(42.25) = 6.5
Similarly,
DF² = DE² + EF²
13² = DE² + 5²
DE² = 13² - 5²
DE² = 144
DE = √(144) = 12
If we are using the concept of similarity, ratio of corresponding sides are equal for similar triangles.
AB / EF = BC / DE = AC / DF
2.5 / 5 = 6 / DE = AC / 13
Consider 2.5 / 5 = 6 / DE
Then DE = (6 × 5) / 2.5 = 12
Consider AB / EF = AC / DF
2.5 / 5 = AC / 13
AC = (2.5 / 5) × 13 = 6.5
Hence the missing lengths are AC = 6.5 and DE = 12.

2. (1, 2)
3. (2, 1)
4. (1, 5)
Answer:
3. (2, 1)

The solutions are the points located inside the shaded region. The only point not located in that region is the point (2, 1). Therefore, (2, 1) is not a solution to the system of inequalities.
36/42 = 24/r what is r
Answer:
r=28
Step-by-step explanation:
36/42 = 24/r (determine the defined range)
36/42 = 24/r , r ≠ 0 ( Reduce the fraction)
6/7 = 24/r (cross multiply)
6x = 168 ( divide both sides)
r=28 , r ≠ 0
Answer:
r = 28
Step-by-step explanation:
Cross multiply and solve for r:
[tex]\frac{36}{42}[/tex] = [tex]\frac{24}{r}[/tex]
36r = 1008
r = 28
So, r = 28

Cary is wrong
Step-by-step explanation:
4* (6-4)= 4* 2=8
I think it is saying (8*2) divided by to, which in that case is 8,
but if it is asking 8 (2/2) then that would also be 8 I believe. I really hope this is correct and you have a great day :)

How does 10 x (-3)^24 simplify to positive 10 x 3^24 and not negative 10 x 3^24 ?
Answer:
Below.-
Step-by-step explanation:
Because when a negative is taken to an even power the results is positive.
So (-3)^24 is positive as 24 is even, and is the same as 3^24, and so the whole expression
10 * (-3)^24 = 10 ^ 3^24.

What is the sum of the measures of the interior angles of a 7-gon?
Answer:
900°
Step-by-step explanation:
What is the sum of the measures of the interior angles of a 7-gon?
The formula to measure the interior angles of a polygon
= (n- 2) × 180 °
Where,
n = number of sides
We are given 7 - gon
This means it has 7 sides = Heptagon
Hence,
The measure of the interior angle is given as:
(7 - 2) × 180°
= 5 × 180°
= 900°
The sum of the interior angles of a 7-gon is 900°

The school is landscaping an area for a soccer field. If the
dimensions are 60 feet by 35 feet. What is the area of the soccer
field?
Answer: 2100 square feet
Step-by-step explanation: 60 x 35=2100
Answer:
2100 ft squared!
Step-by-step explanation:
The formula to find the area of a rectangle is L * W = A
Where A is the total area, and L and W are the dimensions.
Since we know what the dimensions of the rectangles are, we can replace L and W to find out the area. This will look like this: 60 * 35 = A
Now we just have to multiply 60 and 35 to find A. This will simplify to 2100, which means the total are of the rectangle, or in this case, the soccer field, is 2100 ft squared!

The pendulum swings at an arc of 30 cm and its successive swings reduced to 10% of the previous swings. What is the total distance travelled by the pendulum after 5 swings? This problem is an example of what sequence?
Answer:
[tex]S_g= 33.333cm[/tex]
Step-by-step explanation:
From the question we are told that
Arc of 30 cm
10% reduction after each swing
Generally sum of geometric sequence is given by the equation
[tex]S_g=\frac{a(1-r^n)}{1-r}[/tex]
Mathematically solving for total distance traveled we have
[tex]S_g=\frac{30(1-(0.10^5)}{1-(0.10)}[/tex]
[tex]S_g=\frac{30}{0.9}[/tex]
Therefore the total distance traveled by the pendulum after 5 swings
[tex]S_g= 33.333cm[/tex]
