explanation: that’s a right angel, right angels are 90° 90°-42°= 48°
Answer:
a = 48°
Step-by-step explanation:
Forming the equation,
→ 42° + a = 90°
Now the value of a will be,
→ 42° + a = 90°
→ a = 90° - 42°
→ [ a = 48° ]
Hence, the value of a is 48°.

The equation of circle that have diameter of 12 cm is x2+(y-3)2=36
What is equation of circle?
The standard equation of a circle is given by:
(x-h)2 + (y-k)2 = r2
Where (h, k) is the coordinates of center of the circle and r is the radius.
Given, diameter = 12 cm
radius = 6 cm
Hence, center is on y-axis hence, x = 0

The rate of change(slope) of the graph is 7 / 5.
How to find the rate of change(slope)?The rate of change function is defined as the rate at which one quantity is changing with respect to another quantity.
The slope(rate of change) is change in the dependent variable with respect to the change in the independent variable.
The slope is rise over run.
Therefore, let's find the slope of the graph as follows:
slope = y₂ - y₁ / x₂ - x₁
Therefore, using (0, -7) and (5, 0)
slope = 0 - (-7) / 5 - 0

The total number of customers you will assist per week would be 366
Let Total number of customer you assist per week be variable "x"
We have to calculate the value of this variable now,
Given ,
you work Monday to Friday,
Total working days = 6
Number of customer you usually assist = 52 customers per day
This week to hit your goal you have to assist more customers
Number of more customer you need assist = 9 customers per day
So, Total customer you'll assist per day to hit goal = 52 + 9
=> 61 customers per day
Customer you will assist per week = customer assist per day × 6
x = 61 × 6
x = 366

b)1.8s

Answers
The expression that represents the amount in dollars that each paid is (a) 1.2s - 1.2.
What is the percentage?The percentage is a ratio that can be expressed as a fraction of 100.
Given that, Su's Sushi is $2 more than Darbi sushi and the cost of Su's sushi is represented by s.
Let the price of Darbi's sushi is $x.
Then, the price of Su's sushi is
s = x + 2
x = s -2
The total cost is:
x + s
= s -2 + s
= 2s -2
Since they divided the total cost evenly, the cost each paid is:
(2s-2)/2
= s -1
Now, the cost after paying a 20% tip is:
(s - 1) + 20% of (s - 1)
= s- 1 + 20(s-1)/100
= s-1 + 0.2s - 0.2
= 1.2s - 1.2

in which:
Parentheses are the first priority; if they occur.
then:
Exponents are the second priority if they occur.
followed by:
Multiplication and
Division; if any of these occur; and the priority is from the left-hand side to the right-hand side—if they occur. So; multiplication does not necessarily take priority over division. Rather, "Multiplication and Division" are treated equally, as the "next priority", from "left to right"—as they occur/if they occur;
followed by:
Addition and
Subtraction; of any of these occur; and the priority is from the 'left-hand side to the right-hand side—if they occur. So; addition does not necessarily take priority over subtraction. Rather, "Addition and Subtraction" are treated equally, as the "next priority", from "left to right"—as they occur/if they occur.
____
So: For our given problem; we can solve:
" 8(6 + 4) " ; which is the same as:
" 8 * (6 + 4) ";
We have a "multiplication" and a "parentheses" ;
So: The "parentheses" take first priority:
____
"(6 + 4) = 10 " ;
now: " 8 * (6 + 4) " ;
= 8 * 10 = 80 ; which is our answer:
____
Alternate method:
Note the distributive property of multiplication:

So: 8 (6 + 4) = (8*6) + (8*4) ;
= 48 + 32;
= 80 ; which is our correct answer!

rental cost for each movie and each video game.
Rental cost for each movie: $
Rental cost for each video game: $
Answers
Answer:
rental cost of each movie is $2.5
rental cost of each video game is $5.5
Step-by-step explanation:
use x for movie and y for video game. Then you get the equations
2x+12y=71 and 5x+3y=29
then you solve each equation for either x or y.
when you solve for y you will get
y = (71 -2x) / 12 and y = (29 -5x) / 3
because y is the same, you put those equations together
(71-2x) / 12 = (29 -5x) / 3
then solve for x and you get x = 2.5
then you put 2.5 for x in either of the original equations and solve for y.
for both equations you will get y = 5.5

Hint --> The two triangles add up to 180°
Answers
The value of x for the given triangle is 12.
According to the question,
We have the following information:
We have a figure of two triangles joined together and some of the angles are marked.
Now, we observe the figure carefully then the base of both triangles are parallel to each other.
Now, 45° will be the angle of triangle on right hand side because they are vertically opposite angles.
We know that the sum of three angles of triangle is 180°.
For the RHS triangle, let's take third angle to be y:
45+65+y=180
110+y =180
y =180-110
y = 70°
Now, y will be equal to (6x-2) because they are vertically opposite angles.
6x-2 = 70
6x = 70+2
6x = 72
x = 72/6
x = 12
