Actually Welcome to the Concept of the Triangles.
Since there is a linear pair with 40° , the another angle will be 140° ,
also the triangle newly formed is a isosceles one,
hence x = 20°
===> x = 20°
Now apply angle sum property of a triangle on, the other one,
we get as, 70+40+y=180
hence, y = 180-110
y = 70°
Hence angle y ==> 70°

Step-by-step explanation:
Based on the equation 7x+42=y predict the number of customers to visit the frozen yogurt when it's 10 degrees
Answer:
112 visitors
Step-by-step explanation:
Given the prediction equation :
y = 7x + 42
x = temperature
y = number of visitors (customers)
Number of visitors when temperature is 10 degree
y = 7(10) + 42
y = 70 + 42
y = 112
Hence, the model predicts that 112 customers will visit when temperature is 10 degrees

Answer:
12
Step-by-step explanation:
We can see that the base TA is 4, and the second base RS is 2. We can see that the height is 4. The area of a trapezoid is:
[tex]A=\frac{h(b_1+b_2)}{2}[/tex]
Using this, we can substitute, and get:
[tex]A=\frac{4\cdot(2+4)}{2} = \frac{24}{2} = 12[/tex]

write an equation of the line that passes through (0 0) and (2 6)
Answer:
y = 3x
Step-by-step explanation:
Slope equation:
y2 - y1
--------
x2 - x1
----------------------------------------------------------------------------------------------------------------
6 - 0 6
m = ----------- = ----- = 3
2 - 0 2
Your slope is 3.
----------------------------------------------------------------------------------------------------------------
Equation:
y = mx + b
Plug in the slope and you get:
y = 3x + b
----------------------------------------------------------------------------------------------------------------
Now to find b, you can use either coordinate point. So I will show you both ways :)
(0,0) (2,6)
0 = 3(0) + b 6 = 3(2) + b
Multiply 0 and 3 Multiply 2 and 3
0 = 0 + b 6 = 6 + b
Subtract 0 to 0 Subtract 6 from 6
0 = b 0 = b
There is no y-intercept
----------------------------------------------------------------------------------------------------------------
Your answer: y = 3x
Hope this helped :)

You go to the store to buy a Playstation 5 which cost 499 dollars. If you had to
pay San Jose's sales tax which is 9.25%. How would you solve the problem to find
the total cost? *
What is the total cost?*
Answer:
$545.1575
Step-by-step explanation:
Given function:
499,9.25Solve ways:
combine 9.25% of 499 and 499Multiply 9.25 by 0.01:
[tex]9.25%[/tex]·[tex]0.01=0.0925[/tex]Multiply the cost by 0.0925:
[tex]499[/tex]·[tex]0.0925= 46.1575[/tex]Combine 46.1575 by the first value:
[tex]499+ 46.1575= 545.1575[/tex]Therefore, the PlayStation 5 will be a total cost of $545.1575.

If the probability of a cup drink being rasberry flavour is 0.29, what is the probability of a cup drink being cola flavour?
Answer: 0.71
Step-by-step explanation:
Since we have just two flavors, the probability of a cup drink being cola flavour will be calculated below:
P(R) + P(C) = 1
0.29 + P(C) = 1
P(C) = 1 - 0.29
P(C) = 0.71
Therefore, the probability of a cup drink being cola flavour is 0.71.

Lindas aunt zoe charges her a nominal amount for watching her two children aunt zoe charges $2.50 per day plus $1.75 per hour one day linda paid her aunt $14.75 how many hours did aunt zoe watch the children
Answer:
7 hours
Step-by-step explanation:
the function of the earning of Zoe = 2.50 + 1.75h
2.5 = base fixed amount
1.75 varies based on the hours
h = hours
2.50 + 1.75h = 14.75
to solve for h
subtract 2.5 from both sides and then divide by 1.75
14.75 - 2.5 = 1.75h
12.25 = 1.75h
h = 7

1. Make up an equation that has no solution and explain what that means. (Hint: It has to be a real explanation, not just "it doesn't work").
2. Identify the terms, like terms, coefficients, and constants in the expression.
-3a + 9c - 7c + 4 + 10a
Answer:
1. 2x+7=2x+2 (would eventually get 7=2 which isn't true
2. like terms would be -3a and 10a, 9c and -7c, and 4 is by itself----coefficents would be the number before a varible so -3, 9, -7, and 10------finally the constants would be the numbers by itself so 4
(if you simplify this equation it would be 7a + 2c + 4 since you're combining like terms)
Step-by-step explanation:
1. An equation with no solution means that after simplification you determine it isn't possible this would be things like 2=7 or 1=3 which just aren't true so since they aren't a real equation they are labeled as "no solution" (P.S. if you don't know what infinetly many solutions is eithier it's basically when you have an equation that results in an answer like 0=0 or 5=5 where we know that it is true but I't doesnt give a real value for any of the variables so their are infinite possibilities for the variables value)
2. Like terms - terms that share a common variable (or lack therof) so if you had two numbers with the variable "a" after them you could combine them and the same applies with whole numbers so you could add -5 and 7 together
Coefficeints - basically just the variable in an equation so a value like "x" or "a" that comes after a number
Constants - Any number not followed by a varible so any whole number really for example in 4x+3=5 the 3 and 5 would be considered constants as they are real numbers
Graph each equation. Determine the solution of the system of equations. 0 Use the graphing tool to graph the system.

In Las Vegas, a particular sports bet has about a 30% chance of winning. If the bet wins, the bettor will win 15
dollars. If the bet loses, the bettor will lose 10 dollars.
The expected return of placing one of these bets is -2.50 dollars.
Which of the following statements are true?
Choose all answers that apply:
The average return per bet from 2 of these bets must be exactly -2.50 dollars.
It is possible for a bettor to place 2 of these bets and win both of them.
If a bettor places a large number of these bets, they should expect to average a return of about

Find the percent of change. Round to the nearest
tenth, if necessary. Then state whether the percent of
change is an increase or a decrease.
30. From 55 lb to 24 lb
Answer:
Decease in weight by 56.4%
Step-by-step explanation:
From 55 lb to 24 lb,
There is a decrease in the weight from 55 lb to 24 lb.
For the percentage decrease in weight,
Change in weight = 55 - 24
= 31 lb
Percentage change in weight = [tex]\frac{\text{Total change}}{\text{Initial value}}\times 100[/tex]
= [tex]\frac{31}{55}\times 100[/tex]
= 56.36%
≈ 56.4%
Therefore, there is a decease in weight by 56.4%.
