Answer:
[tex]4\frac{1}{12}[/tex] miles.
Step-by-step explanation:
The goal of the family is to hike [tex]11 \frac{2}{3}[/tex] miles in total. Converting this to an improper fraction, we need a total of [tex]\frac{35}{3}[/tex] miles.
On Monday the family completed [tex]2 \frac{1}{12}[/tex] miles, or [tex]\frac{25}{12}[/tex] miles.
On Tuesday the family completed [tex]2 \frac{1}{3}[/tex] miles, or [tex]\frac{7}{3}[/tex] miles.
On Wednesday the family completed [tex]3 \frac{1}{6}[/tex] miles, or [tex]\frac{19}{6}[/tex] miles.
Next, we can add the total amount of hiking the family has completed from Monday-Wednesday.
[tex]distance= \frac{25}{12} + \frac{7}{3} + \frac{19}{6}[/tex]
In order to add these values, we need to convert all of the fractions so that they have the same denominator. The least common multiple (LCM) of 12, 3, and 6 is 12, so the fractions can all be converted into having a denominator of 12.
Monday's distance [tex]\frac{25}{12}[/tex] already has a denominator of 12.
Tuesday's distance is [tex]\frac{7 * 4}{3 * 4} = \frac{28}{12}[/tex].
Wednesday's distance is [tex]\frac{19 * 2}{6 * 2} = \frac{38}{12}[/tex].
Convert the total distance goal to have a denominator of 12 as well. [tex]\frac{35 * 4}{3 * 4} = \frac{140}{12}[/tex].
Sum the total distance the family has walked on Monday-Wednesday. [tex]\frac{25}{12} + \frac{28}{12} + \frac{38}{12} = \frac{91}{12}[/tex].
Subtract this value from the total hiking distance. [tex]\frac{140}{12} - \frac{91}{12} = \frac{49}{12}[/tex]. The family needs to walk [tex]\frac{49}{12}[/tex] miles, or [tex]4 \frac{1}{12}[/tex] miles on Thursday to complete their goal.
As the question told , the goal of they hiking is reaching to the 11 2/3 hours of hiking which means :
The sum of the hours they hiking during those four days must equal 11 2/3 hours .
Suppose they hiking for x hours on Thursday so we have the following equation :
2 1/12 + 2 1/3 + 3 1/6 + x = 11 2/3
To simplify the addition and subtraction of fractions, we must find a common denominator between them ;
The smallest common multiple between the numbers 3, 6, and 12 is the denominator we want, which is 12. But because day 24 is easier to understand, I consider the common denominator of fractions to be 24.
2 + 2 + 3 + 1/12 + 1/3 + 1/6 + x = 11 + 2/3
7 + 2/24 + 8/24 + 4/24 + x = 11 + 16/24
7 + ( 2 + 8 + 4 )/ 24 + x = 11 + 16/24
7 + 14/24 + x = 11 + 16/24
Subtract sides minus 14/24
7 + 14/24 - 14/24 + x = 11 + 16/24 - 14/24
7 + 0 + x = 11 + 2/24
7 + x = 11 + 2/24
subtract sides minus 7
7 - 7 + x = 11 - 7 + 2/24
0 + x = 4 + 2/24
x = 4 + 1/12
x = 4 1/12

Cheryl bought a shirt for $42 and sweater for$30. Write a numerical expression that represents the change Cheryl received from four $20 bills
Answers
Answer:
[tex]Change = \$8[/tex]
Step-by-step explanation:
Given
[tex]Bills = $20\ bills[/tex] (4)
[tex]Shirt = \$42[/tex]
[tex]Sweater= \$30[/tex]
Required
The change
First, we determine the amount paid,
To do this, multiply the number of bills by the worth of each bill.
So, we have:
[tex]Amount = 4 * \$20[/tex]
[tex]Amount = \$80[/tex]
Next, calculate the worth if item bought
[tex]Items = \$42 + \$30[/tex]
[tex]Items = \$72[/tex]
Subtract the items from the amount to get the change.
[tex]Change = \$80 - \$72[/tex]
[tex]Change = \$8[/tex]

Hannah claims that people who live in southern states spend 9 hours more per week outside than do people in northern states. She selects a random sample from each group. The mean number of hours per week that people in southern states spent outside is 18.6, and the mean number of hours per week that people in northern states spent outside is 14.4. A 99 percent confidence interval to estimate the difference in population means (southern minus northern) is (0.4,8.0).
Answers
Answer: Hello your question is incomplete below is the missing part
Which of the following statements about Hannah’s claim is supported by the interval?
A) Hannah is likely to be incorrect because the difference in the sample means was 18.6−14.4=4.218.6−14.4=4.2 hours.
B) Hannah is likely to be incorrect because 9 is not contained in the interval.
C)The probability that Hannah is correct is 0.99 because 9 is not contained in the interval.
D)The probability that Hannah is correct is 0.01 because 9 is not contained in the interval.
E)Hannah is likely to be correct because the difference in the sample means (18.6−14.4=4.2)(18.6−14.4=4.2) is contained in the interval.

Answer:
Length of side LM = 9 units
Length of side AC = 9 units
Length of side LN = 15 units
Step-by-step explanation:
Given:
In Δ LMN
Length of side LM = m
Length of side LN = a
Length of side MN = 15
In Δ ABC
Length of side AB = 6
Length of side BC = 9
Length of side AC = m
Find:
Length of all missing sides
Computation:
We know that both triangle are similar using AA rule
So,
Length of side LM / Length of side MN = Length of side AB / Length of side BC
Length of side LM / 15 = 6 / 9
Length of side LM = [6 x 15] / 9
Length of side LM = 90 / 9
Length of side LM = 9 units
Length of side LM = Length of side AC = m
Length of side AC = 9 units
Length of side MN / Length of side LN = Length of side BC / Length of side AC
15 / Length of side LN = 9 / 9
Length of side LN = 15 units

Option B is correct. The measurement of the angle m in the circle given is 56degrees
Geometry deals with the measurement of properties of lines, solids, and angles.
The diagram given in the question is a circle. To get the value of d, we will use one of the circle theorems which states;
The angle at the vertex is equal to half the sum in its intercepted arcs as shown:[tex]75=\frac{1}{2} (m\angle d - 94)[/tex]
Cross multiply
[tex]75 \times 2 = m \angle d - 94\\150=m \angle d +94\\m \angle d = 150 - 94\\m \angle = 56^0[/tex]
Hence the measurement of the angle m is 56degrees

Point G is (-8,6) Point J is a reflection of point G and is reflected across the x axis what are the coordinates of point J?
Answers
Answer:
(-8, -6)
Step-by-step explanation:
Given the Point G is (-8,6) if Point J is a reflection of point G and is reflected across the x axis, to get the coordinate of point J, we will negate the y coordinate while retaining the x coordinate value
J = (-8, -(6))
J = (-8, -6)
Hence the required coordinate of J is (-8, -6)

multiply 2 by 160934.4, which is
321868.8 cm in 2 miles.
How do you change miles into centimeters?
To convert a mile to a centimeter, multiply the length by the conversion ratio. The length in centimeters is equal to the miles multiplied by 160,934.4.
The distance in km is equal to the distance in miles multiplied by 1.609344. Since 1 mile is equal to 1.609344 km, that's the conversion ratio used in the formula.
