for each pair of similar triangles find the ratio of two side lengths. How do the ratios compare
Answer:
Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion . In other words, similar triangles are the same shape, but not necessarily the same size. The triangles are congruent if, in addition to this, their corresponding sides are of equal length.Step-by-step explanation: ratios
Not sure on this one either
Answer:
B. 113
Step-by-step explanation:
Since ∠AGF is 67° the that would mean that ∠GFE is also 67°, and since it is a Trapezoid, all the angles should add up to 360°. So we have both of the 67's so that means we have 67+67, and the other two angle need to be the same, but to find those we need to do 67+67 = 134, and 360-134=226, and half of 226 will be 113, which is the angle for both of the missing angles, and is the missing angle u are looking for

Using this equation, find the time that the rocket will hit the ground, to the nearest 100th of second.
The time that rocket will hit ground is 8.196 seconds.
What is quadratic equation?An algebraic equation of the second degree in x is a quadratic equation. The quadratic equation is written as ax² + bx + c = 0, where x is the variable, a and b are the coefficients, and c is the constant term. First, there must be a term other than zero in the coefficient of x² (a ≠ 0) for an equation to be a quadratic equation.
Given equation y = -16x² + 121x + 83
let y be the from ground and x be the time,
the time when rocket hit ground y = 0
-16x² + 121x + 83 = 0
solving using quadratic formula
x = (-b ± [tex]\sqrt{b^{2} - 4ac}[/tex])/2a
here a = -16, b = 121 and c = 83
[tex]\sqrt{b^{2} - 4ac}[/tex] = [tex]\sqrt{121^{2} - 4(-16)(83) }[/tex]
= [tex]\sqrt{14641 + 5312}[/tex] = 141.25
x = -(-121 + 141.28)/32 = -0.633
x = -(-121 - 141.28)/32
x = 8.196 second
Hence the time is 8.196 seconds.

If A = r – 2 and B = r^2 – 4r + 5, find an expression that equals 3A + 2B in
standard form.
Since expression = 3A + 2B [subsitute in values of A&B]
⇒ = 3(r – 2) + 2(r² – 4r + 5) [expnad the brackets]
= 3r - 6 + 2r² - 8r + 10 [group like terms ins stan. form]
= 2r² - 8r + 3r + 10 - 6 [simplify like terms]
= 2r² - 5r + 4

Standard form is ax² + bx + c (where x is any variable, in this case 'r', and a,b,c are the coefficients)

Use the vertical line test to determine if the graph represents a function. Type in yes or no for your answer. Please answer as soon as possible !!!
Answer:
No
Step-by-step explanation:
fail the vertical line test. For x=1, we have 2 correesponding Ys. This is not a function.
Hi there!
The graph is a relation.
It doesn't pass the Vertical Line Test. This test is just a vertical line.
If it touches the graph once, then the graph is a function.
If it touches the graph more than once, then the graph is a relation.
Here, the vertical line touches the graph more than once, so the graph is a relation.
Type: no
Therefore, our answer is: noHope this helps!

Step-by-step explanation:
An article in a women's magazine says that women who choose to nurse their babies feel warmer and more receptive toward the infants than mothers
who bottle-feed. The author concludes that nursing has desirable effects on the mother's attitude toward the child. Explain why asserting a cause-and-effect relationship based on this information is suspect, and give another plausible explanation for the association between the decision to bottle-feed or nurse and mothers’ attitudes toward their children.
Asserting a cause - and - effect relationship with highly correlated variables may sometimes be misleading due to the presence of a possible lurking or confounding variable.
Lurking variables cause unintended or spurious association between correlated variables. In the scenario described, a possible confounding variable may be weariness or Fatigue which whereby the mother finds it easier to bottle feed as they have become psychologically disturbed and are prone to be more receptive during these period.
Hence, fatigue is a possible lurking variable in this scenario.

Need help with question number 10. I don’t get it
Answer: False but true
Step-by-step explanation: This question is all about slope. Slope is rise over run (y/x).
Plant 1:
Plant one has a rate of change of 1 for x. You see how it's going up by 1. For y, it's going up by three, which means that the slope is 3/1, which is three. Three is not equal to six.
Plant 2: follow the points that touch the x and y intersections (my teacher calls them "pretty points"). You see that the slope is 1, because it's going up and right by 1, so 1/1.
Although the measurements are wrong, the statment is true, because 3>1.

Jackson has $1.50 in quarters and dimes. Let x represent the number of quarters and y represent the number of dime. Find the domain and range of this situation.
Answer:
3 dimes
Step-by-step explanation:
Part A: 0.10x + 0.25 = 0.80 (dimes are 10 cents or 0.10 dollars, quarters are 0.25 dollars)
Part B: Plug in what you DO know and solve the one you DON’T:
0.10x + 0.25(2) = 0.80
0.10x + 0.50 = 0.80. Subtract 0.50 from both sides:
0.10x = 0.30 (Divide both sides by 0.10)
x = 3

Reduce to simplest form
Answer:
[tex]-\frac{41}{36}[/tex]
Step-by-step explanation:
To add or subtract fractions, we need to make their denominators equal. To do so, we find the Least Common Denominator (LCD), then rewrite the fractions in the equation with that denominator.
The LCD of 9 and 12, the denominators, is 36 because [tex]9*4=36[/tex] and [tex]12*3=36[/tex].
Thus:
[tex]-\frac{5*4}{9*4} =-\frac{20}{36}[/tex] and [tex]-\frac{7*3}{12*3} =-\frac{21}{36}[/tex]
Now, add the fractions together.
[tex]-\frac{20}{36} -\frac{21}{36} =-\frac{20+21}{36} =-\frac{41}{36}[/tex]
Thus, the answer is [tex]-\frac{41}{36}[/tex].
