What value of n makes the inequality true? |n| > |–2.5|
Answer: n > 2.5 or n < -2.5
Step-by-step explanation:
Let's solve your inequality step-by-step.
1. Solve Absolute Value.
|n| > 2.5
We know either n > 2.5 or n < -2.5
n > 2.5 (Possibility 1)
n < -2.5 (Possibility 2)
Your answer is n > 2.5 or n < -2.5

Can someone teach me How to do long division properly?
Step-by-step explanation:
"properly" is very vague.
as your can imagine, particularly in math, where many things are commutative or have other degrees of freedom what do when in what sequence, you will find particularly for the little techniques many different approaches. and most of them are correct.
particularly today I keep scratching my head about what i think is immensely complicated but teachers swear they are helping the students.
anyway, this is how I do divisions by using an example :
73496 ÷ 17
the "window" I use to look at the first number is a long as the second number. in this case 2 digits.
step 1a :
as mentioned, we look at the 2 left most digits (73) and see how often 17 fits inside that as a whole :
73 ÷ 17 = 4
4×17 = 68, so we have a remainder of 73-68 = 5.
I write it like this :
73|496 ÷ 17 = 4
05 (4×7 = 28 and 5 is then 33, carry over 3,
4×1 = 4 plus carry 3 = 7, 0 difference)
step 1b :
pull the next position down
734|96 ÷ 17 = 4
054
step 2a :
we look at the bottom number and divide this by 17.
54 ÷ 17 = 3 and a remainder of 3.
734|96 ÷ 17 = 43
054
03 (3×7 = 21 and 3 is then 24, carry over 2,
3×1 = 3 plus carry 2 = 5, 0 difference)
step 2b :
pull the next position down
7349|6 ÷ 17 = 43
054
039
step 3a :
we look at the bottom number and divide this by 17.
39 ÷ 17 = 2 and a remainder of 5.
734|96 ÷ 17 = 432
054
039
05 (2×7 = 14 and 5 is then 19, carry over 1,
2×1 = 2 plus carry 1 = 3, 0 difference)
step 3b :
pull the next position down
73496| ÷ 17 = 432
054
039
056
step 4a :
we look at the bottom number and divide this by 17.
56 ÷ 17 = 3 and a remainder of 5.
73496| ÷ 17 = 4323
054
039
056
05 (3×7 = 21 and 5 is then 26, carry over 2,
3×1 = 3 plus carry 2 = 5, 0 difference)
step 4b :
pull the next position down. but we have reached the last position before the decimal point. from that moment on we create result numbers after the decimal point.
and because the left number did not have any explicit digits after the decimal point, all the numbers we are pulling down now are 0.
73496.0| ÷ 17 = 4323.
054
039
056
050
step 5a :
we look at the bottom number and divide this by 17.
50 ÷ 17 = 2 and a remainder of 16.
73496.0| ÷ 17 = 4323.2
054
039
056
050
16 (2×7 = 14 and 6 is then 20, carry over 2,
2×1 = 2 plus carry 2 = 4, 1 difference)
step 5b :
pull the next position down. because the left number did not have any explicit digits after the decimal point, all the numbers we are pulling down now are 0.
73496.00| ÷ 17 = 4323.2
054
039
056
050
160
step 6a :
we look at the bottom number and divide this by 17.
160 ÷ 17 = 9 and a remainder of 7.
73496.00| ÷ 17 = 4323.29
054
039
056
050
160
07 (2×7 = 14 and 6 is then 20, carry over 2,
2×1 = 2 plus carry 2 = 4, 1 difference)
step 6b :
pull the next position down. because the left number did not have any explicit digits after the decimal point, all the numbers we are pulling down now are 0.
73496.000| ÷ 17 = 4323.29
054
039
056
050
160
070
step 7a :
we look at the bottom number and divide this by 17.
70 ÷ 17 = 4 and a remainder of 2.
73496.00| ÷ 17 = 4323.294
054
039
056
050
160
070
02 (4×7 = 28 and 2 is then 30, carry over 3,
4×1 = 4 plus carry 3 = 7, 0 difference)
step 7b :
pull the next position down. because the left number did not have any explicit digits after the decimal point, all the numbers we are pulling down now are 0.
73496.0000| ÷ 17 = 4323.294

In the seahorse tank at an aquarium, 70% of the male seahorses
have eggs in their pouches. There are 20 male seahorses in the
tank. Kennedy uses the expression 0.07 x 20 to find the number of
male seahorses with eggs. Explain why Kennedy's expression is
incorrect. How many male seahorses have eggs in their pouches?
Part A: Kennedy's expression is incorrect because 0.07 is 7 percent, not 70.
Part B: The correct expression would be 0.7 * 20, which equals 14
The winner of a golf tournament made two putts for birdies. The lengths of these putts were 15ft 4 in and 9 ft 2in. What’s the total distance of the putts in yards, feet, and inches?
The total distance of the putts in yards, feets and inches be 8 yd 0 ft 6 inches or 8 yd 0.5 ft 0 inches
What is unit conversion?The conversion between different units of measurement for the same quantity, typically through multiplicative conversion factors.
As,
1 yard = 3 foot,
1 feet = 12 inches.
Now the lengths are given 15ft 4 in and 9 ft 2 in.
So, the total distance of the putts be,
=15 ft 4 in + 9 ft 2 in
= 24 ft 6 inches
= 8 yd 0 ft 6 inches or 8 yd 0.5 ft 0 inches

42=-8(3-k)+6(k-3)
Answer:
6
Step-by-step explanation:
42=--24+8k+6k-18
42=-24+14k-18
42=-42+14k
14k=-42-42
-14k=-84
k=84/14
K=6.
Hey there!
42 = -8(3 - k) + 6(k - 3)
-8(3 - k) + 6(k - 3) = 42
-8(3 - 1k) + 6(1k - 3) = 42
-8(3) - 8(-1k) + 6(1k) + 6(-3) = 42
-24 + 8k + 6k - 18 = 42
COMBINE the LIKE TERMS
(8k + 6k) + (-24 - 18) = 42
8k + 6k - 24 - 18 = 42
14k - 42 = 42
ADD 42 to BOTH SIDES
14k - 42 + 42 = 42 + 42
SIMPLIFY IT!
14k = 42 + 42
14k = 84
DIVIDE 14 to BOTH SIDES
14k/14 = 84/14
SIMPLIFY IT!
k = 84/14
k = 6
Therefore, the answer is: k = 6

To Find:
Area of the shaded region
Solution:
Area of shaded region:
[tex] \rm= Area \: of \: trapezium \: ABCD - Area \: of \: Trapezium \: EHGF[/tex]
We know that,
[tex] \rm \: Trapezium = 1/2 × (a+b)×h \: \: \: sq. units [/tex]
So,
[tex] \rm = 1/2 × (a+b)×h \: \: \: - 1/2 × (a+b)×h [/tex]
Trapezium ABCD:
According to the formula,
a =40b=24h = 25Trapezium EHGF:
a = 30b = 16h = 20Substitute:
[tex] \tt= \cfrac{1}{2} (40 + 24) \times 25 - \cfrac{1}{2} (30 + 16) \times \: 20[/tex]
[tex]\tt= \cfrac{1}{2} (64) \times 25 - \cfrac{1}{2} (46) \times \: 20[/tex]
[tex]\tt = \cfrac{1}{2} \times 1600 - \cfrac{1}{2} \times 920[/tex]
[tex] \tt \: = 800 - 460[/tex]
[tex] \rm = 340 \: cm {}^{2} \: or \: sq. \: cm[/tex]
Thus, the area of the shaded region will be 340 cm^2 .

Find the unknown angles of triangles.
Please help me...!!!
Let's take this fun problem step-by-step:
Let's first analyze the triangle: ΔBRE
∠B + ∠E + ∠R = 180
45 + 35 + ∠R = 180
∠R = 100 ⇒ ∠BRE = 100 degrees
Now let's analyze ΔAQD
∠A + ∠Q + ∠D = 180
30 + ∠Q + 50 = 180
∠Q = 100 degrees ⇒ ∠AQD = 180 degrees
Now let's consider another fact:
AQC is a straight line⇒ meaning that ∠AQD + ∠RQC = 180 degrees
⇒ ∠RQC = 180 degrees - ∠AQD = 180 - 100 = 80 degrees
CRE is a straight line⇒ meaning that ∠BRE + ∠BRC = 180 degrees
⇔ ∠BRC = 180 degrees - ∠BRE = 180 - 100 = 80 degrees
Now let's consider ΔQRC:
∠BRC + ∠RQC + ∠QCR = 180 degrees
80 + 80 + x = 180
x = 20 degrees
Answer: 20 degrees
