Answer:
[tex]b<4[/tex]
Step-by-step explanation:
[tex]20b<80[/tex]
[tex]\frac{20b}{20}<\frac{80}{20}[/tex] (Divide both sides of the inequality by [tex]20[/tex] to get rid of [tex]b[/tex]'s coefficient)

The dimensions of an actual swing set are shown. You want to create a scale model of the swing set for a dollhouse using similar triangles. Sketch a drawing of your swing set and label each side length. Then write a similarity statement for each pair of similar triangles and state the scale factor you used to create the scale model.
The dimensions of the scaled drawing are half the lengths of the dimensions of the original drawing
What are scaled drawings?Scaled drawings are diagrams that shows the image of an object drawn in a reduced or enlarged proportional size.
How to determine a scale ratioIf the diagram is to be enlarged, then the scale ratio will be greater than 1.
However, smaller diagrams will have a scale ratio less than 1
In this case, we make use of a scale ratio of 0.5 or 1/2
This means that, the scaled drawing will have its lengths to be half of the original drawing
See attachment for the original drawing and the sketch of the scaled drawings

What is the solution to -2|2.2x - 3.3| = -6.6?
O x=-3
O x=3
O x=-3 or x = 0
O x = 0 or x = 3
The solution to the equation, -2|2.2x - 3.3| = -6.6, which contain an absolute value, is: D. x = 0 or x = 3.
What is the Solution of an Equation with an Absolute Value?To determine the solution, we have to isolate the value and find its value.
Given the equation, -2|2.2x - 3.3| = -6.6:
-2|2.2x - 3.3| = -6.6
2.2x + 3.3 = 3.3
2.2x = 3.3 - 3.3
2.2x = 0
x = 0/2.2
x = 0
Or
2.2x - 3.3 = 3.3
2.2x = 3.3 + 3.3
2.2x = 6.6
x = 6.6/2.2
x = 3
The solution is: D. x = 0 or x = 3

Y is such that 4y _ 7<= 3y and 3y <= 5y +8. What range of values of y satisfies both inequalities
Answer:
-4≤y≤7Step-by-step explanation:
Given the inequality expressions
4y - 7 ≤ 3y and 3y≤5y+8
For 4y - 7 ≤ 3y
Collect like terms
4y - 3y ≤ 7
y ≤ 7
For 3y≤5y+8
Collect like terms
3y - 5y ≤ 8
-2y ≤ 8
y ≥ 8/-2
y ≥ -4
Combining both solutions
-4≤y≤7
Hence the range of values of y that satisfies both inequalities is -4≤y≤7

2.A chemist needs to mix a 12% acid solution with a 32% acid solution to
obtain an 8‐liters mixture consisting of 20% acid. How many liters of each of
the acid solutions must be used?
9514 1404 393
Answer:
1012%: 4.8 L; 32%: 3.2 LStep-by-step explanation:
For mixture problems, I like to use a single variable to represent the quantity of the greatest contributor (greatest cost or greatest concentration). Let that variable be x.
1. In this problem, the amount of the greatest contributor is already fixed, so we'll use x for the amount of walnuts. The cost of the mix is ...
0.80x + 1.25(8) = 1.00(x +8)
2 = 0.2x . . . . . . . . . . . . . . . . . subtract 0.8x+8, simplify
10 = x . . . . . . . . . divide by 0.2
10 pounds of walnuts must be used.
__
2. The amount of acid in the mix is ...
12%(8 -x) +32%(x) = 20%(8)
20%(x) = 8%(8) . . . . . . . . . . . . subtract 12%(8)
x = 8(8)/20 = 3.2 . . . . . . . . . . divide by 20%
8-x = 4.8
3.2 liters of 32% acid must be mixed with 4.8 liters of 12% acid

Comment on mixture problems
The general solution for mixture problems that have a greater contributor (G), a lesser contributor (L), and a mix value (M) is ...
g/l = (M -L)/(G -M) . . . . . . ratio of quantities of G and L
In the first problem, this becomes ...
8/l = (1.00 -.80)/(1.25 -1.00) = .2/.25 = 4/5 ⇒ l = 8(5/4) = 10
In the second problem, this becomes ...
g/l = (20-12)/(32-20) = 8/12 = 2/3 ⇒ g = (2/5)(8) = 3.2; l = (3/5)(8) = 4.8
In this case, we recognize that the ratio of 2 parts to 3 parts means that the greater contributor is 2 of 5 total parts.
|The angles in a triangle are in the ratio 1:1:4
|(a) Find the size of the largest angle?
b) what type of triangle is it?
Since the internal angle sum of a triangle is 180 degrees, and the angles are in ratio if 1:1:4, the angles with that's corresponding to the 1 will have value of 180/6=30 degrees.
The largest angle will have value 30*4=120 degrees.
This is an obtuse triangle because largest angle>90 degrees.

Answer:
x= 64.3
Step-by-step explanation:
To solve for x, you have to use trig. Since you're solving for an angle, you use inverse trig.
the problem gives you your opposite(29) and your adjacent(14), so you will use tangent.
so to set up your equation to type it into your calculator, it will be
[tex]tan^{-1} (\frac{29}{14} )[/tex]
type this into your calculator and you will get x.

Which value of x makes the value of the expression x - 11.5 a negative number?
Answer:
11
Step-by-step explanation:
The absolute value of any positive number is the number itself, so 11 has 11 as an absolute value. Also, the absolute value of a negative number is its (positive) opposite, so also has 11 as an absolute value.
