Answer: x = 8

because The upper triangle is an isosceles triangle (the two sides are equal)

=> 5x + 5 = 45°

<=> x = (45 - 5) : 5

<=> x = 40:5 = 8

Answer:

x = 8

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 given angles and equate to 180

5x + 5 + 5x + 5 + 90 = 180, that is

10x + 100 = 180 ( subtract 100 from both sides )

10x = 80 ( divide both sides by 10 )

x = 8

A lake is stocked with 1,500 young trout. If the number of the original trout alive after x years is given by the function P(x)=

musickatia [10]

The function $P(x)=1500e^{-0.4x}$ gives the number of the original trout alive after x years. When the number of the original trout alive is 300, then

$300=1500e^{-0.4x}$

Solve this equation:

$e^{-0.4x}=\dfrac{300}{1500},\\ \\e^{-0.4x}=\dfrac{1}{5},\\ \\-0.4x=\ln \dfrac{1}{5},\\ \\x=\dfrac{\ln \dfrac{1}{5}}{-0.4}\approx 4.024.$

Answer: after 4.024 year (or 5 year if round to the whole number of years)

David, Stephen and June share £96 in a ratio 2:3:3. How much money does each person get

AveGali [126]

Answer:

David gets £24, Stephen gets £36, and June gets £36.

Step-by-step explanation:

Firstly, add the ratio values together.

2:3:3 ⇒ 2 + 3 + 3 = 8

Next, divide £96 (your total) by 8.

£96 ÷ 8 = £12

Now, we have the number of pounds for 1 value.

Multiply 12 by each ratio value.

12 × 2 : 12 × 3 : 12 × 3

= 24:36:36

Therefore, David gets £24, Stephen gets £36, and June gets £36.

I hope this helped! I would really appreciate it if you would please mark me brainliest! Have a blessed day!
