The proper height of a highway guardrail is 27 inches, but 3 inches higher or lower is acceptable. Which inequality represents the acceptable heights, h, of a highway guardrail?
A.|h+27|≤3
B.|h−3|≤27
C.|h+3|≤27
D.|h−27|≤3
Answer:
Step-by-step explanation:
27 is the "center" of a range of measurements of the height of the guard rail. The height could be as much as 30 inches or as little as 24 inches. The absolute value operator encloses "x - 27," where 27 is the "center." The acceptable excess or acceptable deficiency is 3 inches.
So now we can eliminate possible answers B and C, in both cases because 27 is inappropriately greater than 3.
Narrowing down our choices, we have h + 27 and h - 27 inside the absolute value operator. 27 is a positive quantity (height of the guard rail), so the inequality showing +27 as the "center" is correct; that is
D: |h - 27| ≤ 3 (measurements in inches).
Quadrilateral ABCD is a parallelogram. DE = 6.1 cm and m∠DAB = 120°. Parallelogram A B C D is shown. Diagonals are drawn from point A to point C and from point D to point B and intersect at point E. The length of A D is 10 centimeters and the length of D C is 5 centimeters. What is BC? cm What is m∠BCD? ° What is AB? cm What is EB? cm
Answer:
The answer is below
Step-by-step explanation:
A parallelogram is a polygon (has four sides and four angles) in which opposite sides are parallel and equal to each other. Opposite angles are equal and consecutive angles are supplementary. Also, the diagonals bisect each other.
BC = AD (opposite sides are equal)
BC = 10 cm
m∠BCD = m∠DAB (opposite angles are equal)
m∠BCD = 120°
AB = DC (opposite sides are equal)
AB = 5 cm
EB = DE (diagonals bisect each other at point E)
EB = 6.1 cm
Answer:
BC = 10
m∠BCD?=120
AB=5
EB=6.1

-2x-5 = 19
I need help with this
Answer:
-12
Step-by-step explanation:
First you add five to the 19 and get 24 and then you divide -2x by 24 and you get -12
Answer:
x=-12
Step-by-step explanation:
-2x-5=19
+5 to both sides
-2x=24
÷-2 to both sides and you get -12

The line L1, is y= 5x+1
The line L2, is 2y-10 +3=0
Show how these 2 lines are parallel
Answer:
Step-by-step explanation:
L₁: y = 5x + 1
Slope of L₁ = 5
L₂: Did you mean 2y - 10x +3 = 0 ?
2y = 10x - 3
y = 5x - 1.5
Slope of L₂ = 5
L₁ and L₂ have the same slope, so the lines are parallel.

Answer:
Step-by-step explanation:
formula: a^2 + b^2 = c^2
a^2 + 15^2 = 17^2
a^2 + 30 = 289
-30 -30
a^2 = 259
(square root)
a = approximately 16
You deposit 10,000 into a savings account that compounds quarterly. The account has an interest rate of 3.7%. What would be the value of the investment after 30 year
Answer:
30189.155
Step-by-step explanation:
Recall the compound interest formula :
A = P(1 + r/n)^nt
P = principal = 10000
r = rate = 3.7% = 0.037
n = quarterly = 4
t = 30
A = 10000(1 + 0.037/4)^30*4
A = 10000(1 + 0.00925) ^120
A = 10000(1.00925)^120
A = 10000 * 3.0189155
A = 30189.155

If one inch represents 3 units, what dimensions would you use to draw a rectangular field that is 20 units by 14 units?
Answer:
Step-by-step explanation:
If 1 inch = 3 units,
Therefore 1 unit = ⅓ inches, so to answer your question we have to
Multiply it by 20, to have :
20 units = 20× ⅓ = 20÷3
20 units = 6.66
Therefore we can use the same principle in that of 14 units.
14 units = (14 × ⅓) inches
14 units = 4.66 inches
