Closets tale up 92 square feet of the space in rayas apartment.What is the area of Rayas entire apartment
Answer: 920 ft²
Step-by-step explanation:
Closets take up 92 ft² of Maya's apartment.
From the model presented, closets account for 10% of the entire space in Maya's apartment.
The entire area of the apartment can be represented by x.
The relevant expression is:
x * 10% = 92
x = 92/10%
x = 920 ft²
Given the function f(x) = x2 + 7x + 10, determine the average rate of change of
the function over the interval –5 < x < 3.

Trigonometric ratio
Trigonometric ratio is used to show the relationship between the sides and angles of a right angled triangle.
From the diagram using trigonometric ratio:
[tex]tan(21+19)=\frac{y}{25} \\ \\ y=25tan(40)\\ \\ y=21\ m[/tex]Also:
[tex]tan(21)=\frac{x}{25} \\\\x=25tan(21)\\\\y=9.6\ m[/tex]Length of shadow = y - x = 21 - 9.6 = 11.4 m
The length of the man's shadow produced by the spotlight is 11.4 m.

Answer:
y=5
Step-by-step explanation:
-4y+12=10y-30

y=3
The value of the expression -4 ( y - 3 ) = 5 ( 2y - 6 ) is 3
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be -4 ( y - 3 ) = 5 ( 2y - 6 )
On simplifying the equation , we get
-4y + ( -4 ) ( -3 ) = 10y - 5 ( 6 )
-4y + 12 = 10y - 30
Adding 4y on both sides , we get
14y - 30 = 12
Adding 30 on both sides , we get
14y = 42
Divide by 14 on both sides , we get
y = 3
Therefore , the value of y = 3
Hence , the value of the expression -4 ( y - 3 ) = 5 ( 2y - 6 ) is 3

Find the midpoint of the line segment with the given endpoints. (5.1,5.71) and (6,3.6).
Answer:
The coordinates of the midpoint are (5.55,4.655)
Step-by-step explanation:
Midpoint
The midpoint (xm,ym) of a segment defined by points (x1,y1) and (x2,y2) is calculated as follows:
[tex]\displaystyle x_m=\frac{x_1+x_2}{2}[/tex]
[tex]\displaystyle y_m=\frac{y_1+y_2}{2}[/tex]
We are given the points (5.1 , 5.71) and (6 , 3.6). The coordinates of the midpoint are:
[tex]\displaystyle x_m=\frac{5.1+6}{2}=\frac{11.1}{2}=5.55[/tex]
[tex]\displaystyle y_m=\frac{5.71+3.6}{2}=\frac{ 9.31}{2}=4.655[/tex]
The coordinates of the midpoint are (5.55,4.655)

C. 168°
Step-by-step explanation:
The exterior angle at any vertex of an n-gon will be ...
360°/n
So a 30-gon will have exterior angles of ...
360°/30 = 12°
The adjacent interior angle is supplementary to this, so is ...
180° -12° = 168°
_____
Using the reasonableness test
You know that the interior angles of a square are 90°, and that regular polygons with more sides have larger interior angles. The most any regular polygon's interior angle can be is 180°. The only answer choice between 90° and 180° is the correct choice: 168°.
