quadrilateral a'b'c'd' is the image of quadrilateral abcd under a dilation with a scale factor of 1/3?
Answers
Answer:
6
Step-by-step explanation:
The required measure of the line CD is 6 units, as of the given conditions.
Given that
Quadrilateral a'b'c'd' is the image of quadrilateral abcd under a dilation with a scale factor of 1/3.
The scale factor is defined as the ratio of the modified change in length to the original length.
here,
Given scale factor = 1/3
Now,
C'D'/ CD = 1/3
CD = 3 C'D'
CD = 3 × 2
CD = 6 units
Thus, the required measure of the line CD is 6 units, as of the given conditions.

The three angles of a triangle have
measures of 56°, (2x + 4)º, and xº
What are the measures of the three
angles of the triangle? (TEK 8.8D)
A. 56°, 80°, 44°
B. 56°, 90°, 34°
C. 56°, 84°, 40°
D. 56°, 60°, 64°
Answers
Answer:
56°, 84°, 40°
Step-by-step explanation:
The three angles of triangles have measures of 56°, (2x + 4)º, and xº.
We need to find the measures of the three angles of the triangle.
We know that, the sum of angles of triangle is equal to 180º. Using this property we get :
56°+ (2x + 4)º + xº =180º
Solving for x.
60 + 3x = 180
3x = 120
x = 40º
Other angle, = 2x+4
= 2(40)+4
= 80+4
= 84º
So, the measures of the three angles of the triangle are 56°, 84°, 40°. Hence, the correct option is (c).

Find the values of x,y, and z in the triangle to the right. Help is very appreciated! :)
Answers
The drawing is very poor because it shows that it’s an equilateral triangle but in the same time they made it confusing with using the degree sign on the variables..
Very confusing but the best way to do it is
Y+2x+1=180
Y=179-2x
Z+2x-1=180
Z= 181-2x
We found the previous but knowing that a straight line gives us 180
After that we equate all angles in the triangle to 180 (crazy eh?! Also definition of a triangle all angles make up 180)
X+179-2X+181-2X=180
-3x=180-181-179
X=60
Which gives us Y=59 and Z=61 from the equation we created in the beginning.
Fingers crossed it’s correct. Double check my math !

What is the slope of the line that passes through the points (-3, -9)(−3,−9) and (22, -4) ?(22,−4)? Write your answer in simplest form.
Answers
Answer:
1/5
Step-by-step explanation:
Equation: [tex]\frac{y_{2} - y_{1}}{x_{2} - x_{1}}[/tex]
Points: (-3, -9) and (22, -4)
[tex]y_{2}[/tex] is the second y point that shows up on the question, basically go by order. So it's -4
[tex]y_{1}[/tex] is -9, because again, in order of which coordinates pop-up first in the question
[tex]x_{2}[/tex] is 22, [tex]x_{1}[/tex] is -3
Now input into the equation, to make it easier we'll split the fraction into 2 equations:
[tex]\frac{y_{2} - y_{1}}{x_{2} - x_{1}}[/tex] = [tex]y_{2} - y_{1}[/tex] and [tex]x_{2} - x_{1}[/tex], we'll put them back in a fraction later
[tex]y_{2} - y_{1}[/tex] = -4 - (-9) = -4 + 9 = 5
[tex]x_{2} - x_{1}[/tex] = 22 - (-3) = 22 + 3 = 25
now put it in the fraction, remember y on top x on the bottom:

Matt was babysitting for friend's parents Saturday morning and was paid $10 per
hour for 3 hours. Later that evening, he was babysitting for another couple that paid
him $20 per hour for 5 hours. What was Matt's average rate of pay per hour for the
day?
Answers
Answer:
Matt was paid an average of $10 per hour of babysitting for the day.
Step-by-step explanation:
He babysat in the morning for 3 hours being paid $10 per hour. He later babysat in the evening for 5 hours being paid $20 per hour. Since he was being paid two different amounts throughout the day, the average would be $10. He was being paid atleast $10 per hour for babysitting because even though he was being paid $20 in the evening, the lowest amount of money that he was paid, was $10 making that the average.
The length l of a rectangle is decreasing at a rate of 3 cm/sec while the width w is increasing at a rate of 3 cm/sec. When l=5 cm and w=12 cm, find the rates of change of the area, the perimeter, and the lengths of the diagonals of the rectangle. Determine which of these quantities are increasing, decreasing, or constant.
a) The rate of changes of the area of the rectangle is _______ cm^2/sec
Is the area increasing, decreasing, or constant?
b) The rate of change of the perimeter of the rectangle is ____ cm/sec.
Is the perimeter increasing, decreasing, or constant?
c) The rate of change of the length of the diagonals of the rectangle is ____ cm/sec.
Is the length of the diagonals increasing, decreasing, or constant.
Answers
Answer:
1) dA/dt = -21 cm²/s and Area is decreasing
2)dP/dt = 0 and perimeter is constant
3) dD/dt = 21/13 cm/s and diagonal is increasing
Step-by-step explanation:
We are given that;
length l of a rectangle is decreasing at a rate of 3 cm/sec.
Thus, dl/dt = -3 cm/sec
Also, the width w is increasing at a rate of 3 cm/sec. Thus;
dw/dt = 3 cm/sec
When l=5 cm and w=12 cm;
A) Area is given by the formula;
A = lw
The rate at which area is increasing is;
dA/dt = l(dw/dt) + w(dl/dt)
Plugging in the relevant values;
dA/dt = 5(3) + 12(-3)
dA/dt = 15 - 36
dA/dt = -21 cm²/s
This is less than 0.thus, A is decreasing.
B) Formula for perimeter is;
P = 2l + 2w
rate of change of perimeter is;
dP/dt = 2(dw/dt) + 2(dl/dt)
Plugging in the relevant values, we have;
dP/dt = 2(-3) + 2(3)
dP/dt = 0
Thus,Perimeter is constant
C) the length of the diagonal of a rectangle is given by;
D = √(w² + l²)
Rate of change of diagonal is;
dD/dt = [2w(dw/dt) + 2l(dl/dt)]/(2√(w² + l²))
2 will cancel out in numerator and denominator to give;
dD/dt = [w(dw/dt) + l(dl/dt)]/(√(w² + l²))
Plugging in the relevant values gives;
dD/dt = [12(3) + 5(-3)]/(√(12² + 5²))
dD/dt = (36 - 15)/13
dD/dt = 21/13 cm/s
This is greater than 0.
Thus, diagonal is increasing.

In a study investigating the effect of car speed on accident severity, the vehicle speed at impact was recorded for 5,000 fatal accidents. For these accidents, the mean speed was 46 mph and the standard deviation was 13 mph. A histogram revealed that the vehicle speed distribution was mound shaped and approximately symmetric. (Use the Empirical Rule.) (a) Approximately what percentage of vehicle speeds were between 33 and 59 mph
Answers
Answer:
68%
Step-by-step explanation:
Given that:
Mean speed (m) = 46
Standard deviation (s) = 13
Approximately what percentage of vehicle speeds were between 33 and 59 mph
Obtain the Zscore for P(Z < x) for both values and subtract :
For x = 33
Zscore :
Z = (x - m) / s
Z = (33 - 46) / 13 = - 1
p(Z < - 1) = 0.15866 ( Z probability calculator)
For x = 59
Zscore :
Z = (x - m) / s
Z = (59 - 46) / 13 = 1
p(Z < 1) = 0.84134 ( Z probability calculator)
Hence, 0.84134 - 0.15866 = 0.68268 = 0.68
0.68 * 100% = 68%
