3= 1.5
Answer:
C, 4+x=15
Step-by-step explanation:
since you're trying to find x you need to isolate it, so use the other numbers you have, 19 and 4, subtract 4 from 19, (19-4) to get x=15.

Answer:
determine the area of the square ABCD with AB=5cm and BC=3cm
if √7-3√5 = √x-√y, determine the value of x and y where x>y.
Answer:
x = 45
y = 7
Step-by-step explanation:
To obtain the value of x and y, do the following:
√7 – 3√5
Rearrange
– 3√5 + √7
Multiply through by –1
3√5 – √7 ... (1)
Express 3√5 as a single surd
3√5 = √(3 × 3 × 5)
3√5 = √45
Replace 3√5 with √45 in equation 1
3√5 – √7
√45 – √7
Comparing
√45 – √7 and √x – √y i.e
√45 – √7 = √x – √y
x = 45
y = 7

How much fertilizer containing 30% nitrogen should be mixed with a fertilizer containing 10% nitrogen to get 10L of a fertilizer containing 12% nitrogen?
Answer:
1L of 30% fertilizer and 9L of 10% fertilizer
Step-by-step explanation:
Let x = the amount of fertilizer containing 30% nitrogen.
Let y = the amount of fertilizer containing 10% nitrogen
x + y = 10 because the two fertilizers together will be 10L
0.3x will be the amount of nitrogen in the 30% nitrogen fertilizer, and 0.1y will be the amount of nitrogen in the 10% fertilizer. If you add those together, you will get 12% of the nitrogen in the 10L mixture. This makes this equation:
0.3x + 0.1y = 0.12(10)
0.3x + 0.1y = 1.2
Now we have our two equations.
x + y = 10
0.3x + 0.1y = 1.2
We can use substitution to solve this system of equations.
x = 10 - y
Substituting this into the second equation, we have:
0.3(10-y) + 0.1y = 1.2
3 - 0.3y + 0.1y = 1.2
3 - 0.2y = 1.2
1.8 = 0.2y
9 = y
10 - 9 = 1L
There will be 9L of 10% nitrogen fertilizer and 1L of 30% nitrogen fertilizer.

The linear regression model y=1.8x−76.9 represents the relationship between the temperature (°F) and the number of ice cream cones sold.
Using the model, approximate the temperature when there are 95 ice cream cones sold. Round your answer to the nearest tenth. When they sell 95 ice cream cones, the temperature is approximately _ °F.
Answer:
95.5 °F
Step-by-step explanation:
A linear regression model is used to represent the relationship between two variables in form of a linear equation. A linear regression line equation is in the form Y = a + bX, where X is the independent variable, Y is the dependent variable, b is the slope of the line and a is the Y intercept (the value of y when x = 0).
Given that x represents the temperature (°F) and y represents the number of ice cream cones sold.
We have the equation as y = 1.8x - 76.9.
Given a 95 ice cream cones sold, to find the temperature, we substitute y = 95 and find x:
y = 1.8x - 76.9
95 = 1.8x - 76.9
1.8x = 95 + 76.9
1.8x = 171.9
x= 95.5 °F
When they sell 95 ice cream cones, the temperature is approximately 95.5 °F
Jim has 3 pairs of pants
and 2 shirts. How many
different ways can he
dress?
Answer:
2 to 5 different ways
Step-by-step explanation:
Answer:
12 different ways he can dress
Step-by-step explanation:
Let The Pant be A and Shirt be B
So, we have 3 pair of pants i.e., 6 Pants
Here, We assumed that the pant be A then 6 pants be
A₁ A₂ A₃ A₄ A₅ A₆
Now, For Shirts
We have 2 Shirts
But we assumed that the Shirt be B then 2 Shirts be
B₁ B₂
Then, We will make pair of A and B
A₁ = B₁
A₂ = B₁
A₃ = B₁
A₄ = B₁
A₅ = B₁
A₆ = B₁
A₁ = B₂
A₂ = B₂
A₃ = B₂
A₄ = B₂
A₅ = B₂
A₆ = B₂
Thus, 12 different ways he can dress

A family visits a car show to research information on vehicles they might consider purchasing. Brochures for each vehicle provide helpful information for the vehicle. Which of the following is an example of a continuous quantitative variable that might be included in the brochure?
number of seats
type of transmission
presence of a sunroof
fuel efficiency (in mpg)
An example of a continuous quantitative variable that might be included in the brochure is; A: number of seats
What is the continuous quantitative variable?Quantitative continuous variables are defined as the variables whereby their values are uncountable while also having a number of possibilities that are infinite.
A discrete quantitative variable is a variable that can be counted. This means that they are written in units whereby numbers will be counted and can be assigned.
From the question, the number of seats that are inside the car are countable. Thus, it can be evaluated based on its numerical value, instead of quality. In short, we can even say that the buyers were of the opinion that the more the number of seats that were in the car, the more the number of people the car was able to carry. Thus, we can conclude that the family would love to buy a car that has a reasonable number of seats.
Thus, we can conclude that the type of the transmission is a qualitative variable.

At the movie theatre, child admission is $5.20 and adult admission is $8.70. On Sunday, 134 tickets were sold for a total sales of $885.80. How many adult
tickets were sold that day?
Number of adult tickets that were sold that day is 54.
Given,
Cost of child ticket = $5.20
Cost of adult ticket = $8.70
Total sales of tickets = $885.80
Let the number of child tickets sold on that day be x
Let the number of adult tickets sold on that day be y
Total number of tickets sold on that day = 134
Using the above data, we can draw relations between the given variables and make two equations. Solving the two equations for the two variables will give the answer.
Eq 1 :
5.20x + 8.70y = 885.80
Eq 2 :
x + y = 134
These two equations can be solved using the elimination method.
Multiply Eq 2 with 8.70.
=> 8.70x + 8.70y = 1165.8 - Eq 3
Substract Eq 3 from Eq1 to eliminate the variable y and find the value of variable x
5.20x + 8.70y = 885.80
- 8.70x - 8.70y = - 1165.8
______________________
- 3.5x + 0 = -280
=> 3.5x = 280
=> x = 80
Substituting the value of x in Eq 2
=> x + y = 134
=> 80 + y = 134
=> y = 134 - 80
=> y = 54
Therefore, we get the number of child tickets and adult tickets sold that day as 80 and 54, respectively.
