Answer:
IJ = 12.8
Step-by-step explanation:
Since you are missing 1 side, set up a proportion 8 is to 3.2 as 32 is to x, so
[tex]\frac{8}{3.2} =\frac{32}{x}[/tex] so solve for x by cross multiplying 8x = 102.4, so x = 12.8
Use the estimates from (c) and (d) to calculate the relative change in the average household
income from 2002 to 2012. Round to the nearest one percent. Indicate if the change is an
increase or decrease.
Answers
Answer:
it decreased by 5.55% change of 6%
The relative change is -6% Rounding to the nearest percent.
What are average?The average can be calculated by dividing the sum of observations by the number of observations.
Average = Sum of observations/the number of observations
The relative change can be calculated by dividing the absolute change (the subtraction of the values) by the initial value.
The absolute change is the final value minus the initial value;
Absolute change = 51000 - 54000 = -3000
Now, calculating the relative change;
Relative = -3000/54000
Relative = - 0.0555
Since the relative change is negative, this change indicates a decrease.
Therefore, the relative change is -6% Rounding to the nearest percent.

(4.4, 5.4), (3.2, 8.3), (-7, 15), (23 4/15, 2 7/15)Step-by-step explanation:
1.
Multiply the first equation by 3/2:
3/2×8x + 3/2×2y = 3/2×46 12x + 3y = 69Subtract the second equation:
12x - 7x = 69 - 475x = 22x = 4.4Find y:
4*4.4 + y = 23y = 23 - 17.6y = 5.42.
Double the second equation and subtract the first one:
14x - 4x = 94 - 6210x = 32x = 3.2Find y:
4*3.2 + 6y = 626y = 62 - 12.86y = 49.8y = 8.33.
Subtract the second equation from the first one:
4x - 2x = 62 - 762x = -14x = -7Find y:
4(-7) + 6y = 626y = 62 + 286y = 90y = 154.
Multiply the second equation by 4 and subtract the first one:
16y - y = 4(98) - 4315y = 349y = 349/15y = 23 4/15Find x:

What is the measure of angle S?
A. 27°
B. 58°
C. 95°
D. 180°
Answers
According to the provided diagram, which depicts two congruent triangles, the measure of angle S is 27.
Congruent triangles are what?If all 3 corresponding sides and all 3 corresponding angles are equal in size, the two triangles are said to be congruent. Slide, twist, flip, and turn these triangles to create an identical appearance.
What are the five rules for triangle congruence?If two triangles meet all 5 requirements for congruence, then they are congruent. They are right angle-hypotenuse-side (RAHS), angle-side-angle (ASA), angle-angle-side (AAS), side-side-side (SSS), and side-angle-side (SSS) (RHS). All three equivalent sides of the acronym SSS (side-side-side) are congruent. SAS (side-angle-side) (side-angle-side) Congruence exists between two sides and the angle between them. ASA (angle-side-angle) (angle-side-angle).

for what values of X and Y is quadrilateral ABCD a parallelogram
Answers
Answer:
x = 9
y = 3
Step-by-step explanation:
Since this is a quadrilateral the opposite side lengths must be equal
5x - 20 = 7x - 38
38 - 20 = 7x - 5x
18 = 2x divide both sides by 2
9 = x same goes for y
6x - 31 = 4y + 11 we already know x = 9 so
6×9 - 31 = 4y + 11
54 - 31 - 11 = 4y
12 = 4y divide both sides by 4
3 = y
Determine the multiplier in each situation below.
a. A 44% increase
b. A 93% decrease
Answers
Answer:
Step-by-step explanation:
%s can drive a person crazy.
44% increase
Cost = 100% * x + 44%x
Cost = x ( 100 / 100 + 44/100)
Cost = x (1 + 0.44)
Cost = 1.44 x
93% decrease
Cost = 100%x - 93%x
Cost = x * (100/100 - 93/100)
Cost = x * (1 - 0.93
Cost = 0.07 x
Answer:
1.44 and 0.07
Step-by-step explanation:
(a)
A 44% increase of the original amount (100%) is
100 + 44 = 144% = [tex]\frac{144}{100}[/tex] = 1.44 ← multiplier
(b)
A 93% decrease of the original amount (100%) is
100 - 93 = 7% = [tex]\frac{7}{100}[/tex] = 0.07 ← multiplier

Answers
Answer:
c = 3.3 cm
Step-by-step explanation:
A = 180 - (95 + 45) = 40° (sum of triangle)
a = 3.0 cm
C = 45°
c = ?
Applying the Law of Sines, we have:
[tex] \frac{Sin(40)}{3} = \frac{Sin(45)}{c} [/tex]
Cross multiply
[tex] Sin(40)*c = Sin(45)*3 [/tex]
Divide both sides by sin(40)
[tex] c = \frac{Sin(45)*3}{sin(40)} [/tex]
c = 3.3001886 ≈ 3.3 cm (nearest tenth)
