Find the value of n that makes ΔDEF ∼ΔXYZ when DE = 4, EF = 5, XY = 4(n+1), YZ = 7n - 1, and ∠E ≅∠Y. n =

dalvyx [7]

Answer:

3

Step-by-step explanation:

It's given that ΔDEF ∼ΔXYZ . So the corresponding sides of both triangles will be proportional to each other.

$= > \frac{de}{xy} = \frac{ef}{yz} = \frac{df}{xz}$

DE = 4 ; XY = 4(n + 1) ; EF = 5 ; YZ = 7n - 1

Putting all these values gives ,

$\frac{4}{4(n + 1)} = \frac{5}{7n - 1}$

$= > \frac{1}{n + 1} = \frac{5}{7n - 1}$

$= > 7n - 1 = 5(n + 1)$

$= > 7n - 1 = 5n + 5$

$= > 7n - 5n = 5 + 1$

$= > 2n = 6$

$= > n = \frac{6}{2} = 3$

Lisa is 6 centimeters taller than her friend Ian. Ian is 10 centimeters taller than Jim. Every month, their heights increase by

Temka [501]

Lan is 146 centimeters tall now.

<u><em>Explanation</em></u>

Let, Lan's current height is $h$ centimeters

As Lisa is 6 centimeters taller than Lan and Lan is 10 centimeters taller than Jim, so Lisa's current height = $(h+6)$ centimeters and Jim's current height = $(h-10)$ centimeters.

Every month, their heights increase by 2 centimeters.

So, after 5 months.....

Lan's height = $h+(2*5)=(h+10)$ centimeters,

Lisa's height = $(h+6)+(2*5)= (h+16)$ centimeters and

Jim's height = $(h-10)+(2*5)= h$ centimeters

Given that, the sum of Ian's and Jim's heights will be 140 centimeters more than Lisa's height in 5 months. So the equation will be....

$(h+10)+h= (h+16)+140\\ \\ 2h+10=h+156\\ \\ 2h-h=156-10\\ \\ h=146$

So, the current height of Lan is 146 centimeters.

Andy bought 4 hamburgers snd 2 milkshakes for $13.50. Danny bought 3 hamburgers and 1 milkshake for $9.25. What cost of a hambur

Molodets [167]

A hamburger costs $2.5 and a milkshake costs $1.75

Step-by-step explanation:

Step 1: Form equations from the given details. Let cost of 1 hamburger be H and cost of 1 milkshake be M.

4H + 2M = 13.50 ------ (1)

& 3H + 1M = 9.25 ------ (2)

Step 2: Multiply eq(2) with 2 to make coefficients of M equal.

6H + 2M = 18.50 ------- (3)

Step 3: Subtract eq(3) from eq(1)

⇒ - 2H = - 5

⇒ H = $2.5

Step 4: Substitute value of H in eq(2) to find M.

⇒ 3 × 2.5 + M = 9.25

⇒ 7.5 + M = 9.25

⇒ M = $1.75
