The area of a trapezium is 300sqm and its height is 10m, if one of the parsllel sides is 10m, the length of the other parallel side is
Answer:
50M
Step-by-step explanation:
The area of a trapezium = 1/2 x ( a + b) x h
a and b are the parallel sides
h = height
300sqm = 0.5 x (10 + b) x 10
divide both sides by 10
30 = 0.5 x (10 + b)
Divide both sides by 0.5
60 = (10 + b)
b = 60 - 10 = 50

I believe (x+5)(x-2) would be equal though.
Step-by-step explanation:
(x-5)(x+2) = x²+2x-5x-10
simplify:
x²-3x-10 ≠ x²+3x-10
(x)(x+3) = x²+3x
simplify:
x²-3x ≠ x²+3x-10
(x+3)(x-10) = x²-10x+3x-30
simplify:
x²-7x-30 ≠ x²+3x-10

Find the length of side x I simplest radical form
Answer:
Option A
Step-by-step explanation:
By applying Pythagoras theorem in ΔABC,
(Hypotenuse)² = (Leg 1)² + (Leg 2)²
AC² = AB² + BC²
AC² = 6² + 5²
AC = [tex]\sqrt{61}[/tex]
Similarly, by applying Pythagoras theorem in ΔACD,
AD² = AC² + CD²
(10)² = [tex](\sqrt{61})^2[/tex] + x²
x² = 100- 61
x² = 39
x = √(39)
Option A will be the answer.

The decimal form of 1/3 is a repeating decimal. Are all the multiples of 1/3 also repeating decimals? Explain.
plz help
Answer:
No.
Step-by-step explanation:
1=3*1/3
2=6*1/3
3=9*1/3
......
Yes, All the multiples of 1/3 also repeating decimals.
What is Division method?
Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.
For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
Given that;
The decimal form of 1/3 is a repeating decimal.
Now,
Since, The decimal form of 1/3 is a repeating decimal.
As, 1 / 3 = 0.33333...
And, Some of the multiples of 1/3 are;
1 / 3 = 1×2 / 3×2
= 2 / 6
= 0.33333....
And, 1 / 3 = 1×3 / 3×3
= 3 / 9
= 0.33333....
1 / 3 = 1×4 / 3×4
= 4 / 12
= 0.33333....
Thus, Yes, All the multiples of 1/3 also repeating decimals.

find the slope and y-intercepts of the line below & write the equation of the line.
Answer:
m=3 b=-2 y=3x-2
Step-by-step explanation:
The slope/m is 3 because the rise is 3 and the run is 1. Rise over run and you get 3/1 also known as 3.
The y-intercept point/b is -2 because you can look at the graph and the point where the line touches the y-axis is the y-intercept/b
The equation is written in the format of y=mx+b so y and then m is the slope then add x after the slope, then write the y intercept.

Lenny made 50 sandwiches in 12 minutes for a catering job recently. How many sandwiches could he make in an hour if he worked at the same rate?
Answer: in an hour and working at the same rate, Lenny will make 250 sandwiches
Step-by-step explanation:
Number of sandwiches made in 12 minutes =50
Number of sandwiches made in 1 hour = ??
1 Hour = 60 mins
Therefore, Number of sandwiches made in 60 mins = (60 x 50) /12
=5 x 50 = 250 sandwiches
PLEASE HELP!!! Find the length of the midsegment to the nearest tenth.
Answer:
Midsegment is 35.
Step-by-step explanation:
TL; DR:
The smaller triangle (with a base of 6x + 5) has side lengths that are twice as small as the entire triangle (the one with a base of 3x+55). So, 2(6x+5) = 3x + 55. x = 5, so the midsegment is 35.
Look at the photo attached below.
Here is the statement/reason:
1. ED ║ AB (Midsegments are parallel to the base)
Note: Then, CA and CB are transversals
2. Then, m∠CED = m∠EAB (corresponding angles)
3. m∠CDE = m∠DBA (corresponding angles)
4. ΔCED is similar to ΔCAB (angle angle)
5. CA = CE + EA
6. CA = 39 + 39 = 78 (Substitution, algebra)
7. ED/AB = CE/CA (similar triangles)
Note: You can also use CD and CB
8. (6x+5) / (3x+55) = 39 / 78 (substitution)
9. (6x + 5) / (3x + 55) = 1 / 2 (algebra)
10. 12x + 10 = 3x + 55, x = 5 (algebra)
11. ED = 6x + 5 (given)
12. ED = 6*5 + 5 = 35 (substitution, algebra)
An explanation of the algebra:
(6x+5) is twice as small as (3x + 55). So, we can write this equation:
2(6x+5) = 3x + 55
12x + 10 = 3x + 55
Subtract 3x from both sides.
9x + 10 = 55
Subtract 10 from both sides.
9x = 45
x = 5.
Now, put that into ED.
6x + 5 = 6 * 5 + 5 = 35

1. Amir, who is two-thirds of his sister, Manisha's
age, is 10 years of age. Find Manisha's age.
Answer:
Manisha age = 15 years
Step-by-step explanation:
Let
Manisha age = x
Amir = 2/3 of Manisha age
Amir = 10 years
Amir:
2/3 of x = 10
2/3 * x = 10
2/3x = 10
x = 10 ÷ 2/3
= 10 × 3/2
= (10*3)/2
= 30/2
= 15
x = 15 years
Therefore,
Manisha age = 15 years

the the quotient of the opposite of a number and negative ten
Answer:
The symbol for absolute value is two vertical lines. Since opposites are the same distance from the origin, they have the same absolute value. For example, the absolute value of "negative 10" is ten, and the absolute value of "positive 10" is also 10.
:))
Answer: x/10
Step-by-step explanation:
the quotient of the opposite of a number and negative ten
Well
The opposite of a number is -x
And negative ten is written as -10
now we need the quotient of -x and -10
If you were asked the quotient of 10 and 2 it would be 10÷2 or 5
So the quotient of -x and -10 would be [tex]\frac{-x}{-10} = \frac{x}{10}[/tex]

Find the area of the compound shape below.pls help
Answer:
22cm²
Step-by-step explanation:
For the area of triangle,
base = 2 + 2 + 2 = 6cm
height = 4cm
Area = 1/2 x base x height
= 1/2 x 6 x 4
= 12cm²
For area of the rectangle,
length = 5cm
breadth = 2cm
Area = length x breadth
= 5 x 2
= 10cm²
Area of compound shape = 12 + 10 = 22 cm²
Ika nilai rata-rata 20 orang murid adalah 7,5. Kemudian, seorang murid menyusul ulangan dan mendapatkan nilai 8. Berapa nilai rata-rata sekarang?
Answer:
Average grade now = 7.524
Step-by-step explanation:
Given - If the average score of the 20 students is 7.5. Then a student follows the test and gets a grade of 8.
To find - What is your average grade now?
Proof -
Given that,
Average score of 20 students = 7.5
So,
Total value of students = 20 × 7.5 = 150
Now,
Given that, One person added ang his grade is 8
So,
So Total value of 21 students = 150 + 8 = 158
Now,
Average score of 21 students = [tex]\frac{158}{21}[/tex] = 7.5238
∴ we get
Average grade now = 7.524
Write a polynomial function rule for g(x)+f(x)

Consider the given polynomials are:
[tex]f(x)=7x^3+x^2-4x+10[/tex]
[tex]g(x)=x^2-5[/tex]
To find:
The polynomial function rule for [tex]g(x)+f(x)[/tex].
Solution:
We need to add both functions to get [tex]g(x)+f(x)[/tex].
[tex]g(x)+f(x)=(x^2-5)+(7x^3+x^2-4x+10)[/tex]
[tex]g(x)+f(x)=x^2-5+7x^3+x^2-4x+10[/tex]
On combining like terms, we get
[tex]g(x)+f(x)=7x^3+(x^2+x^2)-4x+(10-5)[/tex]
[tex]g(x)+f(x)=7x^3+2x^2-4x+5[/tex]
Therefore, the required function is [tex]g(x)+f(x)=7x^3+2x^2-4x+5[/tex].
