If the restaurant expected 105 people for lunch, using the given probability, the number of those who would order the daily special is D. 55.
What is the probability?Probability is the likelihood or chance that an expected outcome will occur amid many possible results.
Probability gives a fractional value of the whole when it is not 100% certain (when the possibility is 1)or 100% uncertain (when the chance is zero).
Like ratios and proportions, probabilities are depicted using fractions, decimals, or percentages.
The probability of ordering the daily special = 52%
The expected number of lunchers = 105
The number of those expected to order the daily special = 55 (105 x 52%)
Thus, if 105 are expected to attend the lunch, the probable number that will order is Option D.

Answer:
a) m∠6 = 55 and m∠8= 55 - 20 --> m∠8= 35 x = 55
b) m∠7 = 40 and m∠9 = 140 x = 40
c) m∠8 = 46 and m∠7 = 46 x = 18

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

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

Dwade is thinking about buying a laptop that costs $559, but he would also have to pay 7% sales tax. How much would Dwade pay in tax?
Answer:
$39.13
Step-by-step explanation:
559 x 7 is 3913 divided by 100 since its a percent is 39.13
The required amount paid for tax is obtained as $39.13.
How to calculate the percent value of the tax?In order to calculate the percent value take the ratio of the tax amount to the amount of the goods and then multiply it by 100.
The tax value is often written in terms of percent.
The price of laptop is given as $559.
And, the percent value of sales tax is 7%.
The amount of tax can be calculated as follows,
7% × Price of laptop
= 7% × 559
= 7/100 × 559
= $39.13
Hence, the amount paid by Dwade for the sales tax is $39.13.

Find the area of shaded region.
Answer:
340 cm^2
Step-by-step explanation:
Given:
Figure
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 .
