Need help urgently
Answer:
[see below]
Step-by-step explanation:
"Two-Fifths of a number is 48."
(2/5)n = 48
((2/5n)(5/2) = 48 *(5/2)
n = 120
------------------------------------
120 * (3/4) = 90

Cho hình thang ABCD(AB//CD) có AB=40cm CD=80cm BC =50cm AD=30cm cmr ABCD là hình thang vuông
From A draw AG // BC cuts CD at WO
We have: Trapezoid ABCD (assumption)
⇒ AB // CD
⇒ AB // GC (because G ∈ CD)
Considering quadrilateral ABCG, there are:
AB // GC (proven above)
AG // BC (assumption)
⇒ Quadrilateral ABCG is a parallelogram
⇒ AB = GC = 40 cm
AG = BC = 50 cm
We have: DG = CD - GC (because G ∈ CD)
DG = 80 - 40
⇒ DG = 40(cm)
Considering ΔAGD, there are:
AG2=AD2+DG2AG2=AD2+DG2
502=302+402⇒502=302+402
⇒502=900+1600⇒502=900+1600
502=2500⇒502=2500
⇒502=502⇒502=502
⇒ AGD square at D
⇒ Trapezoid ABCD is a square trapezoid

Answer:
a)2x-3y
b)4(9a-4)
Step-by-step explanation:
a)we want to expand the following expression:
[tex] \displaystyle - \frac{1}{4} ( - 8x + 12y)[/tex]
well to do so we consider distributive property thus distribute:
[tex] \displaystyle - \frac{1}{4} (- 8x )+ - \frac{1}{4}( 12y)[/tex]
reduce fraction which yields:
[tex] \displaystyle - \frac{1}{4} (- 8x )+ - \frac{1}{4}( 12y) \\ \\ \displaystyle 2x + ( - 3y)[/tex]
simplify Parentheses:
[tex] \displaystyle \boxed{ 2x - 3y}[/tex]
b)in the expression there's a common factor of 4 therefore factor it out:
[tex] \displaystyle 9.4a - 4.4 \\ \\ \displaystyle \boxed{4(9a - 4)}[/tex]

Answer:
Since this number is small we know that the exponent will be negative.
In scientific notation the decimal must be between the first two NON zero numbers. So move the decimal and count how many positions it was moved.

Is (5, 0) a solution to the equation y = x + 5?
Guys I need help
Answer:
no
Step-by-step explanation:
substitute the x- coordinate 5 into the equation and if the result is equal to the y- coordinate 0 then it is a solution
y = 5 + 5 = 10 ≠ 0
Then (5, 0 ) is not a solution to the equation

Write the equation of the line that passes through the points (8, –1) and (2, –5) in standard form, given that the point-slope form is y + 1 = (x – 8).
Answer:
A linear equation in the standard form is written as:
y = a*x +b
where a is the slope and b is the y-intercept.
If we know that the line passes through the points (a, b) and (c, d), then the slope can be written as:
a = (d - b)/(c - a)
So we know that our line passes through the points (8, -1) and (2, -5)
then the slope will be:
a = (-5 - (-1) )/(2 - 8) = (-4/-6) = 2/3
Then our line is something like:
y = (2/3)*x + b
to find the value of b, we can use the fact that we know that our line passes through the point (2, -5)
this means that when x = 2, we must have y = -5
replacing these values in the equation we get:
-5 = (2/3)*2 + b
-5 = 4/3 + b
-5 - 4/3 = b
-15/3 - 4/3 = b
-19/3 = b
then the equation is:
y = (2/3)*x - 19/3
(in the question you wrote the point-slope form, but you can see that it does not work for the second point, so there may be a mistake there, as the slope is missing)
The actual equation in the point-slope form is:
y + 1 = (2/3)*(x - 8)
Answer:
The answer is 2x + -3y = 19

Mike, a Salvation Army bell ringer, has 20% as many quarters as nickels in his cup. If Mike has $6.00 in quarters and nickels, how many nickels does he have?
5.8 Nickels
Step-by-step explanation:
Let x rep no of Nickels in Mike's cup
Then x - 0.2 = Number of quarters in Mike's cup
0.2x = Amount of money that mike has from the nickels
1 ( x - 0.2) = Amount of money that Mike has from the quarter
Then,
0.2x + 1 (x - 0.2) = 6
Expand the bracket
0.2x + x - 0.2x = 6
x = 6
Recall
x - 0.2 = 0
6 - 0.2 = 5.8
Therefore, Mike has 5.8 nickels for the quarter

(5.4)
O B. (5,1)
10
(5,-3)
O C. (5,-)
O D. (10,1)
SUBMIT
Answer:
c
Step-by-step explanation:
To find the midpoint the formulas
x=x1+x2/2 and y=y1+y2/2 are used
in this case x1 is 5,x2 is 5,y1 is 4 and y2 is -3
therefore
x=5+5/2.
=10/2
=5
y=4+(-3)/2
=1/2
The midpoint of a line segment divides the line into equal segments
The midpoint of the line segment is (5,1/2)
The endpoints of the line is given as:
(5,4) and (5,-3)
The midpoint of the line is calculated as:
(x,y) = 0.5(x1 + x2, y1 + y2)
So, we have:
(x,y) = 0.5(5 + 5, 4 - 3)
Evaluate the sum and difference
(x,y) = 0.5(10, 1)
Evaluate the product
(x,y) = (5, 1/2)
Hence, the midpoint of the line segment is (5,1/2)

A and B are partner in a business .A contribution RS 20000 and B rs 30000 a however acts as a manager the understanding being that of the profit should get 25% for his service as manager the remaining divided in the ratio of their contribution .If B ges Rs 1350 Ashish share what would A get
Answer:
Rs 1,650
Step-by-step explanation:
The given contribution are;
A contributes Rs 20,000, and B contributes Rs 30,000
The percentage of the profit A receives as manager = 25%
The amount of the profit divided in the ratio of their contribution = The remaining profit (75%)
The amount B gets = Rs1,350
The amount A gets = required
The ratio of their contribution at which the remaining profit is shared = 20,000:30,000 = 2:3
Where, out of 5 parts of 75% of the profits, B gets 3, while A gets 2
Let P represent the profit, we have;
B's share = 3/5× 0.75 × P = 1,350
∴ P = (5 × 1,350/3)/0.75 = 3,000
A gets 25% of the profits and 2/5 of the 75% remaining profit
∴ The amount A gets = 0.25×3000 + (2/5)×0.75×3000 = 1,650
Or simply put;
A gets the remainder of the profit which is Rs 3,000 - Rs 1,350 = Rs 1,650
what is the significant figures for 0.045325
Answer:
There are 5 significant digits in 0.045325 and they are 4, 5, 3, 2, and 5.
Step-by-step explanation:
Significant digits rules:
All non-zero numbers count as significant digitsLeading zeroes (zeroes in front of any non-zero numbers) are never significant digitsZeroes in-between non-zero numbers count as a significant digitsTrailing zeroes (zeroes after all non-zero numbers) count only if there is a decimalIn 0.045325, the two zeroes are leading zeroes and therefore do not count. The rest of the digits, (4, 5, 3, 2, and 5) are all non-zero and therefore count. Thus, there are 5 significant digits in 0.045325.
find the LCM and hcf of 72 and 162 , leaving the LCM in prime factors
=========================================================
Explanation:
Find the prime factorization of 72 and 162
72 = 8*9 = 2^3*3^2162 = 2*81 = 2*9^2 = 2*(3^2)^2 = 2*3^4Here's a simplified version of each
72 = 2^3*3^2162 = 2*3^4We have these unique primes: 2, 3
Circle the terms that have the largest exponents for each of those unique primes. So you'll circle 2^3 and 3^4. Those items circled will multiply together to get the LCM.
This means 2^3*3^4 is the LCM (lowest common multiple).
2^3*3^4 turns into 648, but your teacher wants you to keep the LCM in prime factor form.
------------------------------
Now onto the HCF (highest common factor; aka GCF).
Looking at
72 = 2^3*3^2162 = 2*3^4We again see '2's and '3's as the unique primes. Both have at 1 copy of '2' between them. They also both have 3^2 between them. It might help to think of 3^4 as 3^2*3^2.
Those common factors you circled are then multiplied.
Overall, the HCF is 2*3^2 = 2*9 = 18
-----------------------------
Side note: The HCF is useful to help reduce fractions, while the LCM is useful to help find the LCD (lowest common denominator) when adding or subtracting fractions of different denominators. There are other applications of each of these.
Answer:
LCM= 648
HCF= 18
