Answer:

The average cost of each dinner at Dave's party is <u>$5.79</u>.

Step-by-step explanation:

Given:

Dave ordered dinner for a party of 10 people.

Three people ordered the $4.75 chicken dinner, two people ordered the $4.95 fish dinner, and five had the beef dinner at a cost of $6.75 each.

Now, to find the average cost of each dinner at Dave's party.

So, we get the total amount for the dinner:

Three people ordered the $4.75 chicken dinner.

$4.75\times 3=14.25$

Two people ordered the $4.95 fish dinner.

$4.95\times 2=9.90$

Five had the beef dinner at a cost of $6.75.

$6.75\times 5=33.75$

Total amount of dinner = $14.25+9.90+33.75=\$57.90.$

Now, to get the average cost of each dinner of 10 people we divide the total amount of dinner by 10:

$57.90\div 10$

$=\$5.79.$

Therefore, the average cost of each dinner at Dave's party is $5.79.

Some fireworks are fired vertically into the air from the ground at an initial speed of 80 feet per second. The equation for thi

EastWind [94]

Answer:

Vertex (-2.5,-300)

Step-by-step explanation:

We are given with h(t)=-16 t^2 +80 t. We are asked to find the vertex.

X-coordinate of vertex = $\frac{-b}{2a}$

Where 'a' is coefficient of $t^{2}$ term

'b' is coefficient of 't' term.

From given function, a= -16

b=80

So,

x-coordinate of vertex = $\frac{-80}{2(-16)}$

=-2.5

y-coordinate of vertex = $-16(-2.5)^{2} +80(-2.5)$

Simplify it,

=-100 -200

= -300

So, vertex is at (-2.5, -300).

Answer:

a). 5√6

$\sqrt{10} \times \sqrt{15} \\ = ( \sqrt{5} \times \sqrt{2} ) \times ( \sqrt{5} \times \sqrt{3} ) \\ = {( \sqrt{5}) }^{2} \times ( \sqrt{2} \times \sqrt{3} ) \\ = 5 \times ( \sqrt{6} ) \\ = 5 \sqrt{6}$

Answer:

112 people

Step-by-step explanation:

$\frac{4}{50}$ = $\frac{x}{1400}$ write the proportion where x is the number of people with a missplaced time

50x = 5600 cross multipy

x = 112 divide both sides by 50
