If the legs of a right triangle are given by x^2 - y^2 and 2xy then which expression equals the hypotenuse ? Choose all that apply
Answers
Answer:
[tex]\sqrt{\left(x^2-y^2\right)^2+\left(2xy\right)^2}[/tex]
Step-by-step explanation:
Hypotenuse of a right triangle can be found using the Pythagorean theorem which states that both legs squared and added is equal to the hypotenuse squared. In other words, if A and B are legs and C is the hypotenuse:
[tex]C=\sqrt{A^2+B^2}[/tex]
We are told that one of the legs is [tex]x^2-y^2[/tex] and the other is [tex]2xy[/tex] so we get [tex]\sqrt{\left(x^2-y^2\right)^2+\left(2xy\right)^2}[/tex] when we substitute the legs into the formula presented above.

A farmer sells a dozen eggs at the market for 2.00 and one of his bags of gains for 5.00 he sold 5 time as many bags of grains as he has dozens of eggs. By the end of the day he has made 243.00 worth of sales. How many bags of grain did he sell
Answers
Answer:
45 bags
Step-by-step explanation:
Cost of a dozen eggs = 2
A bag of grain = 5
Let :
dozens of eggs sold = x
Bag of grains sold = 5x
Total sales worth = 243
Quantity sold * price
2* x + 5 * 5x
2x + 25x = 243
27x = 243
x = 243 / 27
x = 9
Bags of grains sold = 5x = 9*5 = 45 bags

Is value of X in the equation 6x+3+4x= 1/2(9+10x)
Answers
Answer:
x = 0.3
Step-by-step explanation:
6x + 3 + 4x = 1/2 (9 + 10x)
=> 10x + 3 = 1/2 *9 + 5x
=> 5x + 3 = 9 / 2
=> 5x = 9 / 2 -3
=> 5x = (9 - 6) / 2
=> 5x = 3 / 2
=> x = 3 / 10
=> x = 0.3

Kenneth Drew a scale drawing of an apartment the scale of the drawing was 2 meters:1 meter the living room is 6 m long in real life how long is the living room in drawing
Answers
Answer:
3 meters
Step-by-step explanation:
Given the scale drawing :
2m : 1m
Length of living room in real life = 6 m long
2 meter = 1 meter
Real life = scale drawing
If length = 6 meter long ;
using cross multiplication :
2 meter = 1 meter
6 meter = x
2x = 6
x = 6/2
x = 3 meter
Length of living room in drawing = 3 meters

If you want to solve this problem you would need to multiply 13 by 5 and then add 12, 16, 14, and 8 together and subtract it from your product of 13 and 5.
After that just check your answer by seeing if the mean of all the numbers is the same.

15. Considera um losango em que uma diagonal tem 8cm e cuja área é 12cm^2. Qual é o comprimento do lado do losango, arredondado às décimas? Nota: Indica apenas o valor numérico usando algarismos. (Não escrevas unidades de medida na resposta.)
Answers
Answer:
4,3cm
Step-by-step explanation:
Passo 1
Um losango tem 2 diagonais, cujos comprimentos não são iguais
Temos que encontrar o comprimento da segunda diagonal
A fórmula é dada como:
Área de um losango = 1/2 (d1 × d2)
Área do losango = 12 cm²
d1 = Comprimento da primeira diagonal = 8cm
d2 = Comprimento da segunda diagonal = x
12 = 1/2 (8 × x)
12 = 1/2 (8x)
12 = 4x
x = 12/4
x = 3cm
O comprimento da segunda diagonal = 3 cm
Passo 2
A fórmula do comprimento da lateral de um losango é dada como:
s = √d1² + d2² / 2
d1 = 8cm
d2 = 3 cm
s = √8² + 3² / 2
s = √64 + 9/2
s = √73 / 2
s = 8,5440037453 / 2
s = 4,2720018727 cm
Aproximadamente = 4,3 cm

Rachel left home for school at 7:45 one morning. She returned home at 4:05 that afternoon. How many hours and minutes was she gone? (The number of minutes in your answer must be less than 60.)
Answers
Answer:
8 hours 20 minutes
Step-by-step explanation:
Given that :
Time Rachel left for school = 7:45 a.m
Time she returned Home = 4:05 p.m
Time for which Rachael was gone :
4:05 p.m - 7:45 a.m
7:45 a.m to 3:45 p.m= 8 hours
3:45pm to 4:05 pm = 20 minutes
= 8 hours 20 minutes
Rachael was gone for 8 hours 20 minutes
The segments formed by the altitude to the hypotenuse of a right triangle are 8 and 10. Find the shorter leg of that triangle.
Answers
Answer: 6
Step-by-step explanation:
Since the hypothenuse is 10 and the larger leg of the triangle is given as 8, the shorter leg will be calculated as the square of the hypothenuse minus the square of the longer leg after which we find the square root of the value gotten. This will be:
Shorter leg² = 10² - 8²
Shorter leg² = 100 - 64
Shorter leg² = 36
Shorter leg = ✓36
Shorter leg = 6
