Since the two angles that you have are vertical angles, we know that vertical angles are congruent, so you have to set them to equal each other.

x+24=5x-36
-4x+24=-36
-4x=-60
x=15

We now have the value of x so now we plug it in for each expression of each angle.

x+24=?
15+24=39

5x-36=?
5(15)-36=?
75-36=39

A shop is having a sale all items are reduced work out the sale price of an item normally priced at £60

Naddik [55]

Question:

A shop is having a sales all items are reduced by 25%. Work out the sale price of an item normally priced at £60?

Answer:

The new price is £45

Step-by-step explanation:

Given

$Sales\ price = \pounds 60$

$Rate = 25\%$

First, calculate the reduction

$Reduction = Rate * Sales\ price$

$Reduction = 25\% * \pounds 60$

$Reduction = \pounds 15$

The new price is:

$New = Sales\ price - Reduction$

$New = \pounds 60 - \pounds 15$

$New = \pounds 45$

Write a function in terms of t that represents the situation.

yuradex [85]

Given that opulation of 100,000 decreases by 2% each year.

Now question says to write a function in terms of t that represents the situation.

Question is talking about population decrease so we can apply decay formula. which is given by:

$P(t)=P_0(1-r)^t$

Where A is the population at any time t.

$P_0$ is the initial population so $P_0=100000$

r is the rate of decrease so r=2%=0.02

t is the number of years

Now plug those values, we get:

$P(t)=100000(1-0.02)^t$

$P(t)=100000(0.98)^t$

Hence required function is $P(t)=100000(0.98)^t$ .
