Blank 1=8
Blank 2=3
Blank 3=11
Answer:
triangle=8, diamond=3, star=11
Step-by-step explanation:
First you want to start with the equation that only has only shape/variable.
triangle ÷ 2 = 4
multiply both sides by 2 to find that triangle=8.
Now we can plug triangle in another equation.
2+diamond+diamond=triangle
2+diamond+diamond=8
subtract 2 from both sides
diamond+diamond=6
because we know diamond and diamond will be the same, we can divide 6 by 2 to find diamond=3.
Now we can go to the top equation
triangle + diamond + star = 22
8 + 3 + star = 22
11 + star = 22
star = 11

a plumber chargers a base fee of $55 for a service call plus $55 per hour for each hour worked during the service call. use your equation to calculate how much money it will cost if the plumber works 4 hours
Answer:
The plumber will charge $275
Step-by-step explanation:
Models
Models are used to explain and predict the behavior of real objects or systems and are used in a variety of scientific disciplines.
The situation described in the question asks us to build a mathematical model for the charges for the service of a plumber.
The base fee is often called the fixed fee, which charged even if there is no service time. The plumber charges a base fee of $55.
The variable fee is that who changes for each hour worked. The plumber charges $55 per hour, so the charge for t hours of service is 55t.
The total charges of the plumber are modeled as:
C(t)=55t+55
If the plumber works t=4 hours, the cost will be:
C(4)=55*4+55=$275
The plumber will charge $275

The value of r if DM = 60 according to the question is; 11
According to the diagram given;
The line DM = DG + GM
where DG = 4r and GM = r + 5The line DM is therefore;

The inverse of a function [tex]f(x) = \sqrt{3x + 6}[/tex] is [tex]f^{-1} (x) = \frac{x^{2}-6 }{3}[/tex].
Here,
A function is given as, [tex]f(x) = \sqrt{3x + 6}[/tex]
We have to find the inverse of given function.
What is Inverse function?
An inverse function is a function that undoes the action of the another function.
Now,
A function is given as, [tex]f(x) = \sqrt{3x + 6}[/tex]
To find inverse function,
Replace f(x) by y in the equation,
[tex]y = \sqrt{3x + 6}[/tex]
[tex]y^{2} = 3x + 6\\y^{2} -6 = 3x \\x = \frac{y^{2} - 6\\}{3}[/tex]
Replace every x by a y and solve for y, we get;
[tex]y = \frac{x^{2} - 6\\}{3}[/tex]
Replace y by [tex]f^{-1} (x)[/tex], we get,
[tex]f^{-1} (x) = \frac{x^{2}-6 }{3}[/tex]
Hence, The inverse of a function [tex]f(x) = \sqrt{3x + 6}[/tex] is [tex]f^{-1} (x) = \frac{x^{2}-6 }{3}[/tex].

<B is a complement of <A and m<A = 65.2° find m<B
Answer:
Step-by-step explanation:
<B is a complement of <A
=> m<A + m<B = 180°
65.2° + m<B = 180°
m<B = 180° - 65.2° =114.8°
Answer:
24.8
Step-by-step explanation:
Complementary means they add u to 90°. So to find the measurement of ∠B you must subtract ∠A from 90°. ∠A = 65.2. 90 - 65.2 = ∠B. 90 - 65.2 = 24.80°

Allison works in a department store selling
clothing. She makes a guaranteed salary of $350
per week, but is paid a commission on top of her
base salary equal to 15% of her total sales for the
week. How much would Allison make in a week in
which she made $300 in sales? How much would
Allison make in a week if she made xx dollars in
sales?
Answer:
a. $395
b. $(350 + 0.15x)
Step-by-step explanation:
Her income in a week can be written as;
$350 + 15% of sales
a. In the case of $300 sales in a week
Mathematically, that would be;
$350 + 15% of $300
$350 + (15/100 * 300)
$350 + $45 = $395
b. In the case of $x in sales
= $350 + 15% of x
= $350 + (15/100 * x)
= $350 + 0.15x
= $(350 + 0.15x)

Answer:
D. 1, 5, 7, 9, 11, 14, 16
Step-by-step explanation:
Your welcome ;)
The angles whose measurement are same as that of ∠3 are -
∠1 , ∠5 , ∠7 , ∠9 , ∠11 , ∠14 , ∠16.
What area parallel lines?
Two or more lines that lie in the same plane, equidistant from each other and never intersect each other are known as parallel lines.
Given is a figure in which - t || x and k || w and m∠3 = 20°.
The angles whose measurement are same as that of ∠3 are -
∠3 = ∠1 (Vertically opposite angles)
∠3 = ∠5 (Alternate interior angles) ... [1]
∠5 = ∠7 (Vertically opposite angles)
∠3 = ∠7 ( from [1] )
∠4 = 180 - ∠3 (Straight angle)
∠4 = ∠10 (opposite angles of a parallelogram are equal)
∠10 = 180 - ∠9 (Straight angle)
We can write -
∠4 = ∠10
180 - ∠3 = 180 - ∠9
180 - 180 - ∠3 = - ∠9
∠3 = ∠9 .... [2]
∠9 = ∠11
∠3 = ∠11 ( from [2] ) .... [3]
∠11 = ∠14 (Alternate interior angles)
∠3 = ∠14 ( from [3] ) .... [4]
∠14 = ∠16 (Vertically opposite angles)
∠3 = ∠16 ( from [4] )
Therefore, the angles whose measurement are same as that of ∠3 are -
∠1 , ∠5 , ∠7 , ∠9 , ∠11 , ∠14 , ∠16

7. The length of a rectangle is two more than its width. The perimeter of the rectangle is 36 feet. What are the dimensions (length and width) of the rectangle?
*Show work*
Step-by-step explanation:
length = x + 2
width = x
x + x + (x+2) + (x+2) = 36 ft
4x + 4 = 36 ft
4x = 32 ft
x = 32 ÷ 4
x = 8 ft
dimensions = length x width
= (x+2) × x
= (8+2) × 8
= 10 ft × 8 ft
