He needs an 83%
if you use the equation (77-x)/2=80 it’ll tel you the average he needs to achieve his goal

The answer is 89 percent because (80-77)x3=9 so 89

Students make 97.5 ounces of liquid soap for a craft fair. They put the soap in7.5 -ounce bottles and sell each bottle for $4.

Neporo4naja [7]

Answer:

<h2> $58.5</h2>

Step-by-step explanation:

Step one:

given data

the total amount of ounces= 97.5 ounces

we are told that the capacity of one bottle is 7.5 ounce

this means that they can actually fill up 97.5/7.5= 13 bottles

Step two:

We are told that one bottle was sold for $4.5

<u>Hence they will sell 13 bottles for 13*4.5= $58.5</u>

In ⊙O, ST and VT are tangents. m∠STV = 22°. Find the value of a, b, and m∠SOV.

Rasek [7]

Answer:

$\huge \orange {\boxed {a =202\degree}}$

$\huge \purple {\boxed { b = 158\degree}}$

$\huge \red {\boxed {m\angle SOV = 158\degree}}$

Step-by-step explanation:

In $\odot$ O, ST and VT are tangents at points S and V respectively.

$\therefore OS\perp ST, \:and\: OV\perp VT$

$\therefore m\angle OST=m\angle OVT = 90\degree$

In quadrilateral OSTV,

$m\angle SOV +m\angle OST+m\angle OVT+m\angle STV = 360\degree$

(By interior angle sum postulate of a quadrilateral)

$m\angle SOV +90\degree +90\degree +22\degree = 360\degree$

$m\angle SOV +202\degree = 360\degree$

$m\angle SOV = 360\degree-202\degree$

$\huge \red {\boxed {m\angle SOV = 158\degree}}$

$\because b = m\angle SOV$

(Measure of minor arc is equal to measure of its corresponding central angle)

$\huge \purple {\boxed {\therefore b = 158\degree}}$

$\because a + b= 360\degree$

(By arc sum property of a circle)

$\therefore a = 360\degree - b$

$\therefore a = 360\degree -158\degree$

$\huge \orange {\boxed {\therefore a =202\degree}}$
