A scale drawing of a house shows the house has a height of 11.5 inches. If the scale is 1 inch = 3 feet, how tall is the house in real life?
Group of answer choices
34.5 feet
11.5 feet
3.8 feet
14.5 feet
Answer:34.5
Explanation: So you see that 1 inch is 3 feet and there are 11.5 inches so you put 1 inch 11 times and you'll get 33 and then there is half a inch so half o 3 is 1.5 so if you add 33 plus 1.5 you'll get 34.5.

HOPE IT HELPED YOUAnswer two questions about Equations A and B:
A. 5x = 3x
B. 5 = 3
1) How can we get Equation B from Equation A?
a) add/subtract the same quantity to/from both sides
b) add/subtract a quantity to/from only one side
c) multiply/divide both sides by the same non-zero constant
d) multiply/divide both sides by the same variable expression
2) Based in the previous answer, are the equations equivalent? In other words, do they have the same solution?
a) Yes
b) No
Answer: D multiply/divide both sides by the same variable expression , Then it’s B
Step-by-step explanation:
An equation is formed of two equal expressions. The correct options are D and A, respectively.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
1.) We can get equation B from equation A, by dividing both sides of the equation by x.
5x = 3x
5x / x = 3x /x
5 = 3
Hence, We can get equation B from equation A, by multiplying/dividing both sides by the same variable expression. The correct option is D.
2.) For the previous equations, the two sides of the equation or the two expressions on both sides of the equation are not equal, because 5 is not equal to 3.
Although, the equation may become, true if the value of x is 0, otherwise it is not possible.
Hence, the correct option is A.

4x^4+12x^2+8 solve ✖➖➕➗
Step-by-step explanation:
Simplifying 4x4 + -12x2 + 8 = 0 Reorder the terms: 8 + -12x2 + 4x4 = 0 Solving 8 + -12x2 + 4x4 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '4'. 4(2 + -3x2 + x4) = 0 Factor a trinomial. 4((1 + -1x2)(2 + -1x2)) = 0 Factor a difference between two squares. 4(((1 + x)(1 + -1x))(2 + -1x2)) = 0 Ignore the factor 4.
Subproblem 1
Set the factor '(2 + -1x2)' equal to zero and attempt to solve: Simplifying 2 + -1x2 = 0 Solving 2 + -1x2 = 0 Move all terms containing x to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + -1x2 = 0 + -2 Combine like terms: 2 + -2 = 0 0 + -1x2 = 0 + -2 -1x2 = 0 + -2 Combine like terms: 0 + -2 = -2 -1x2 = -2 Divide each side by '-1'. x2 = 2 Simplifying x2 = 2 Take the square root of each side: x = {-1.414213562, 1.414213562}
Subproblem 2
Set the factor '(1 + x)' equal to zero and attempt to solve: Simplifying 1 + x = 0 Solving 1 + x = 0 Move all terms containing x to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + x = 0 + -1 Combine like terms: 1 + -1 = 0 0 + x = 0 + -1 x = 0 + -1 Combine like terms: 0 + -1 = -1 x = -1 Simplifying x = -1
Subproblem 3
Set the factor '(1 + -1x)' equal to zero and attempt to solve: Simplifying 1 + -1x = 0 Solving 1 + -1x = 0 Move all terms containing x to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + -1x = 0 + -1 Combine like terms: 1 + -1 = 0 0 + -1x = 0 + -1 -1x = 0 + -1 Combine like terms: 0 + -1 = -1 -1x = -1 Divide each side by '-1'. x = 1 Simplifying x = 1
Solution
x = {-1.414213562, 1.414213562, -1, 1}
Find the distance between (1,1) and (13,6)
Answer:
The distance is 13 units
Step-by-step explanation:
13 - 1 = 12
6 - 1 = 5
12² + 5² = c²
144 + 25 = c²
√169 = c
c = 13
(I could have used the distance formula, but the pythagorean theorem is shorter for this problem)
a recipe calls for 3 1/2 teaspoons of mustard seeds, 4 cups of tomato sauce, and 6 3/4 cups of beans, you use 2 2/3 cups of tomato sauce. how many teaspoons of mustard seeds don you need? how many cups of beans do you need?
Answer:
For a recipe call,
Number of teaspoons of mustard seeds =
Number of cups of tomato sauce = 4
