Answer:

The vertex of this graph is (5, 3)

Step-by-step explanation:

In order to find the vertex of any graph in vertex form, we need to look at the base form.

f(x) = a|x - h| + k

The point (h, k) is the vertex. You can see that 5 lines up with the h term and 3 lines up with the k term. This gives us a vertex of (5, 3)

Divide the actual building's measurements by the replica's measurements.

$\frac{400}{20}=20\\\\\frac{320}{16}=20$

The measurements of the actual building are divided by 20 not 12.
The crew member's calculation is incorrect.

What is 90 decreased by 40%?

vaieri [72.5K]

Because it's decreasing, you use the formula (1-x/100)y with x the percentage decreased which is here 40, and y the number decreased which is here 90
So we get
(1-40/100) * 90
(100/100 - 40/100) * 90
60/100 * 90
5400/100
54
So 90 decreased by 40% is 54
Hope this Helps :)

A bonus of £2100 is shared by 10 people who work for a company. 40 percent of the bonus is shared equally between 3 managers. Th

Alja [10]

Answer:

Salesman is not correct

Step-by-step explanation:

First we calculate the share of salesman when 60 percent of bonus is shared among 7 salesmen:

Bonus Share For 7 Salesmen = (0.6)(£ 2100)

Bonus Share For 7 Salesmen = £ 1260

Now, this is equally divided among 7 salesmen:

Bonus Share of 1 Salesmen (when 60% is shared) = S₁ = £ 1260/7

S₁ = £ 180

Now, we calculate the share each salesmen get if bonus is equally divided among 10 people:

Bonus Share of 1 Salesmen (when equally shared) = S₂ = £ 2100/10

S₂ = £ 210

S₂/S₁ = £ 210/£ 180

S₂/S₁ = 1.16

S₂ = 1.16S₁

S₂ = 116% of S₁

This means that if bonus is equally divided between all 10 people then the salesman will get 16 percent more money.

<u>Therefore, salesman is not correct</u>
