Answer:

the answer should be 133 for the measure of angle x because first of all to find the answer you need to know that vertical and complementarty equals always 180 degrees so you set up this equation x+47=180

x+47-47= 180 - 47

x= 133

if you want to check the work you add 133 plus 47 getting an answer of 180 degrees so 133 is the correct answer and have a great day.

Mia and Luke made 85 origami together. Mia made 4 pieces of origami every 3 minutes. Luke made 3 pieces of origami every 4 minut

julia-pushkina [17]

For ease of solving, let's first find the rate of Mia and Luke per minute. Since Mia can do 4 pieces every 3 minutes, then she can do $\frac{4}{3}$ of a piece per minute. Luke on the other hand can do $\frac{3}{4}$ of a piece per minute.

To find how many pieces they made, we first need to find the time it took for them to make the pieces. We assign $t$ as the time Mia spent making origami. Since Luke spent 5 more minutes, we can denote his time as $t+5$ .

Putting this into an equation we'll get:
$\frac{4}{3}t+ \frac{3}{4}(t+5)=85$
$\frac{4}{3}t+ \frac{3}{4}t+\frac{15}{4}=85$
$\frac{25}{12}t=81.25$
$t=39$

Therefore, Mia made pieces of origami for 39 minutes. Knowing this, we can find out the number of pieces of origami she made:
$39* \frac{4}{3} =52$

ANSWER: Mia made 52 pieces of origami.

F(x)=2x-3 and g(x)=x^2-5, find (fog) (x) and (gof) (x)

Alexxandr [17]

F(g(x)) = 2(x^2-5)-3
= 2x^2-13

g(f(x)) = (2x-3)^2 - 5
= 4x^2 + 9 -12x -5
= 4x^2 -12x + 4

Find the width of a rectangle 25 feet and the perimeter is 80

lukranit [14]

$\huge\underline{\red{A}\blue{n}\pink{s}\purple{w}\orange{e}\green{r} -}$

Given - a rectangle with length 25 feet and perimeter 80 feet

To calculate - width of the rectangle

We know that ,

$\bold{Perimeter \: of \: rectangle = 2(l + b)} \\$

where b = width / breadth of rectangle

‎ ‎ ‎

substituting the values in the formula stated above ,

$\bold{80 = 2(25 + b)} \\ \\\bold{ \implies \: 25 + b = \cancel \frac{80}{2} } \\ \\ \bold{\implies \: 25 + b = 40 }\\ \\ \bold{\implies \: b = 40 - 25 }\\ \\\bold{ \implies \: b = 15 \: feet}$
