Answer:
The area of that bedroom in real life is of 216 square feet.
Step-by-step explanation:
Real dimensions:
One of the bedrooms on the blueprint is a rectangle measuring 3 inches by 4.5 inches.
The scale is that each inch on the drawing represents 4 feet in real measure.
So the dimensions of the bedroom are:
3*4 = 12 feet by 4.5*4 = 18 feet.
What is the area of that bedroom in real life?
Rectangular bedroom, so the area is the multiplication of the dimensions.
12*18 = 216 square feet.
The area of that bedroom in real life is of 216 square feet.
The formula v= u + at can be used to calculate
Rearrange the formula to make u the subject.
Answer:
u = v - at
Step-by-step explanation:
v = u + at
v - at = u + at - at
v - at = u
u = v - at

A chef plans to mix 100% vinegar with Italian dressing. The Italian dressing contains 7% vinegar. The chef wants to make 310 milliliters of a mixture that contains 19% vinegar. How much vinegar and how much Italian dressing should she use?
Answer:
Amount of vinegar. 100% : 20 milliliters
Amount of Italian dressing: 140 milliliters
Step-by-step explanation:
Let's call A the amount of vinegar. 100%
Let's call B the amount of Italian dressing . 12% vinegar
The resulting mixture should have 23% vinegar, and 160 milliliters.
Then we know that the total amount of mixture will be:
Then the total amount of pure antifreeze in the mixture will be:
Then we have two equations and two unknowns so we solve the system of equations. Multiply the first equation by -1 and add it to the second equation: We substitute the value of B into one of the two equations and solve for A.

The solution is,
(x - 3)²/3² - (y + 4)²/2² = 1 ⇒ (0 , -4) , (6 , -4)
(x - 4)²/7² - (y + 6)²/5² = 1 ⇒ (-3 , -6) , (11 , -6)
(y + 5)²/5² - (x - 4)²/8² = 1 ⇒ (4 , 0) , (4 , -10)
(y + 7)²/7² - (x + 2)²/4² = 1 ⇒ (-2 , 0) , (-2 , -14)
(x + 1)²/9² - (y - 1)²/11² = 1 ⇒ (8 , 1) , (-10 , 1)
What is hyperbola?We know that, the standard form of the equations of the hyperbola
- The standard form of the equation of a hyperbola with center (h , k)
and transverse axis parallel to the x-axis is (x - h)²/a² - (y - k)²/b² = 1
- The coordinates of the vertices are (h ± a , k)
- The standard form of the equation of a hyperbola with center (h , k)
and transverse axis parallel to the y-axis is (y - k)²/a² - (x - h)²/b² = 1
- The coordinates of the vertices are (h , k ± a)
here, we have,
Lets solve the problem
# (x - 3)²/3² - (y + 4)²/2² = 1
∵ (x - h)²/a² - (y - k)²/b² = 1
∴ a = 3 , b = 2 , h = 3 , k = -4
∵ The coordinates of the vertices are (h ± a , k)
∴ The coordinates of the vertices are (3 - 3 , -4) , (3 + 3 , -4)
∴ The coordinates of the vertices are (0 , -4) , (6 , -4)
* (x - 3)²/3² - (y + 4)²/2² = 1 ⇒ (0 , -4) , (6 , -4)
# (y - 1)²/2² - (x - 7)²/6² = 1
∵ (y - k)²/a² - (x - h)²/b² = 1
∴ a = 2 , b = 6 , h = 7 , k = 1
∵ The coordinates of the vertices are (h , k ± a)
∴ The coordinates of the vertices are (7 , 1 - 2) , (7 , 1 + 2)
∴ The coordinates of the vertices are (7 , -1) , (7 , 3)
* No answer for this equation
# (x - 4)²/7² - (y + 6)²/5² = 1
equation of hyperbola:
∵ (x - h)²/a² - (y - k)²/b² = 1
∴ a = 7 , b = 5 , h = 4 , k = -6
∵ The coordinates of the vertices are (h ± a , k)
∴ The coordinates of the vertices are (4 - 7 , -6) , (4 + 7 , -6)
∴ The coordinates of the vertices are (-3 , -6) , (11 , -6)
* (x - 4)²/7² - (y + 6)²/5² = 1 ⇒ (-3 , -6) , (11 , -6)
# (y + 5)²/5² - (x - 4)²/8² = 1
equation of hyperbola is:
∵ (y - k)²/a² - (x - h)²/b² = 1
∴ a = 5 , b = 8 , h = 4 , k = -5
∵ The coordinates of the vertices are (h , k ± a)
∴ The coordinates of the vertices are (4 , -5 + 5) , (4 , -5 - 5)
∴ The coordinates of the vertices are (4 , 0) , (4 , -10)
* (y + 5)²/5² - (x - 4)²/8² = 1 ⇒ (4 , 0) , (4 , -10)
# (y + 7)²/7² - (x + 2)²/4² = 1
∵ (y - k)²/a² - (x - h)²/b² = 1
∴ a = 7 , b = 4 , h = -2 , k = -7
∵ The coordinates of the vertices are (h , k ± a)
∴ The coordinates of the vertices are (-2 , -7 + 7) , (-2 , -7 - 7)
∴ The coordinates of the vertices are (-2 , 0) , (-2 , -14)
* (y + 7)²/7² - (x + 2)²/4² = 1 ⇒ (-2 , 0) , (-2 , -14)
# (x + 1)²/9² - (y - 1)²/11² = 1
∵ (x - h)²/a² - (y - k)²/b² = 1
∴ a = 9 , b = 11 , h = -1 , k = 1
∵ The coordinates of the vertices are (h ± a , k)
∴ The coordinates of the vertices are (-1 + 9 , 1) , (-1 - 9 , 1)
∴ The coordinates of the vertices are (8 , 1) , (-10 , 1)
* (x + 1)²/9² - (y - 1)²/11² = 1 ⇒ (8 , 1) , (-10 , 1)

716x7 multiply with expanded form
Answer:
The expanded form is y=716x7
Step-by-step explanation:
Expanded form or expanded notation is a way of writing numbers to see the math value of individual digits. When numbers are separated into individual place values and decimal places they can also form a mathematical expression. 5,325 in expanded notation form is 5,000 + 300 + 20 + 5 = 5,325.
Solve the system by substitution
Answer:
(-5, -30)
Step-by-step explanation:
We start with the equation:
y = 6x
y = -4x - 50
Since both of them are equal to y, we can substitute the 6x into y. So:
6x = -4x - 50
Now we can solve for x. Add 4x to both sides...
6x = -4x - 50
+4x +4x
10x = -50
Now, divide both sides by 10.
10x = -50
10 10
x = -5
So, we now know that x is -5. Now we know this, we can substitute -5 where we see x. It works in both equations, so I will do both.
y = 6(-5)
y = -30
And...
y = -4(-5) - 50
y = 20 - 50
y = -30
As you can see, both equations show that y = -30. To check our work, let's plug in the values.
-30 = 6(-5)
-30 = -30
Also:
-30 = -4(-5) - 50
-30 = -20 - 50
-30 = -30
So, we can see that both of the equations gave us the same answer. So, our answer is x = -5 and y = -30, so the ordered pair is: (-5, -30). Hope this helps you!
