Answer:

[tex]14 \frac{3}{8}[/tex]

Step-by-step explanation:

I assume you mean this:

[tex]8 \frac{7}{8} +(7 \frac{5}{6} -2\frac{1}{3} )[/tex]

Lets begin with the parentheses. When operating with fractions, we need them to have the same denominator. Looking at the expression in the parenthesis, we can see that the denominator of 5/6, that being 6, is twice that of 1/3, that being 3. Thus, if we multiply the numerator and denominator of 1/3 by 2, the result will be a fraction of same value, but with denominator 6, which we can work with.

[tex]\frac{1*2}{3*2}[/tex]

[tex]\frac{2}{6}[/tex]

Now we can replace this in the original parenthesis

[tex](7 \frac{5}{6} -2\frac{2}{6})[/tex]

We can now evaluate the parenthesis. 7-2=5, which leaves us with 5 5/6 - 2/6. Since the two fractions have the same denominator, we can subtract the numerator of 2/6 from 5/6. This gives us with 3/6, which we add to the 5 from before.

[tex]5\frac{3}{6}[/tex]

The numerator and denominator of 3/6 are both divisible by three, so we can simply the fraction.

[tex]5\frac{1}{2}[/tex]

Now that we have solved the parenthesis, we can plug our solution back into the original expression.

[tex]8 \frac{7}{8} +5\frac{1}{2}[/tex]

We now have a similar problem to the parenthesis, where our fractions have different denominators. However, you may notice that the denominator of 7/8 (8) is four times larger than the denominator of 1/2 (2). Thus, if we multiply the numerator and denominator of 1/2 by four, we will have a new fraction of equal value, but with denominator 8.

[tex]\frac{1*4}{2*4}[/tex]

[tex]\frac{4}{8}[/tex]

Now lets update our expression with this information.

[tex]8 \frac{7}{8} +5 \frac{4}{8}[/tex]

8+5=13[tex]13\frac{7}{8} +\frac{4}{8}[/tex], so we can further simplify the expression.

Since the denominators of the fractions are the same, we can combine the numerators. 7+4=11

[tex]13 \frac{11}{8}[/tex]

We can simplify the fraction by taking one whole out of it (8/8) and adding it as 1 instead. 11-8=3, thus the fraction that remains is 3/8.

[tex]14 \frac{3}{8}[/tex]

The operation 8 7/8+(7 5/6-2 1/3) evaluates to a final result of 14 3/8.

To evaluate this mixed number operation, we must first convert each mixed number into an improper fraction.

8 7/8 is the same as 71/8 and 7 5/6 as 47/6 and 2 1/3 as 7/3.

Now, conduct the operation inside the parenthesis, which is subtraction: 47/6 - 7/3.

To subtract fractions, they must have the same denominator. Here, the least common multiple of 3 and 6 is 6. So you have 47/6 - 14/6 equals 33/6 reduced to 5 1/2.

Then add this quantity to 8 7/8 which equals to 14 3/8 when converted to a mixed number.

To determine the students selected to go to the board, start with the fourth student and then select every ninth student thereafter. Thus, the students chosen are the 4th, 13th, 22nd, and 31st students who enter the classroom.

The question involves determining which students a professor will select to go to the board based on a specific selection process. The professor decides to randomly select the fourth student who enters the classroom and every ninth student after that. To find out who these students are, we begin by identifying the fourth student initially. After the fourth student, every ninth student subsequently means we add 9 to the initial student's number to find the next student.

The fourth student who enters

The fourth student + 9 = the 13th student

The 13th student + 9 = the 22nd student

The 22nd student + 9 = the 31st student

Therefore, the students selected to go to the board are the 4th, 13th, 22nd, and 31st students who enter the classroom.

The students who will be going to the board are students 4, 9, 18, and 27.

Let’s determine the students who will be going to the board based on the professor’s selection criteria:

1. The fourth student who enters the classroom.

2. Every ninth student after that.

Let’s find the student numbers:

1. The fourth student corresponds to the 4th position.

2. The ninth student corresponds to the 9th position.

3. The 18th student corresponds to the ninth student after that (since 9 + 9 = 18).

4. The 27th student corresponds to the ninth student after the 18th student (since 18 + 9 = 27).

Therefore, the students who will be going to the board are students 4, 9, 18, and 27.

Answer:

(1, -3)

Step-by-step explanation:

Solve the system of equations of the two lines:

10x-3y=19 ------> eq 1

5x+4y=-7 --------> eq 2

Solve by elimination:

eq 2 x 2

2( 5x+4y) = 2(-7 )

10x + 8y = - 14 ------> eq 3

eq3 - eq 1:

(10x + 8y) - (10x-3y) = - 14 - 19

10x + 8y - 10x + 3y = -33

8y + 3y = -33

11y = -33

y = -3  (substitute back into eq 1)

10x - 3y = 19

10x - 3(-3) = 19

10x + 9 = 19

10x  = 19 - 9

10x = 10

x = 1

Answer:

The temperature at noon was 37 °F.

Step-by-step explanation:

Given:

Temperature at midnight is  34 °F.

Reduction in temperature by 6:00 a.m. is 8°. So, temperature after reduction is given as the difference in temperature at midnight and morning.

Therefore, temperature by 6:00 a.m. in the morning is given as:

Reduced temperature = Midnight temperature - Reduction in temperature.

Reduced temperature = 34 °F - 8 °F = 26 °F.

Now, by noon, the temperature is increased by 11 °F. Therefore, the final temperature by noon is addition of 11 degree to the temperature that was in the morning. Therefore,

Temperature at noon = Temperature in morning + Increase in temperature.

Temperature at noon = 26 °F + 11 °F = 37 °F.

So, the temperature at noon is a 3 °F increase to the temperature at midnight and is equal to 37 °F.

Answer:

If X is the starting weight, total pounds lost in three months is

(0.132X + 2.37)lbs

Step-by-step explanation:

Let the starting weight be X(lb)

Let the target ending weight be Y(lb)

Since Rollie ended with 3(lbs) above goal weight, final weight is Y+3(lb)

Each month, Rollie lost 1/3 of the difference between current weight and goal weight, hence

In the first month, Rollie lost 1/3 of (X - Y)

but since Rollie ended up with 3lbs above target ending weight, the actual weight loss is 1/3(X - Y) + 3

Hence  by the end of the first month, Rollie's new weight is X - (1/3(X - Y)) + 3

which is equal to

X - 1/3X + 1/3Y - 3.

= 2/3X + 1/3Y - 3

By the second month, Rollie's starting weight is 2/3X + 1/3Y - 3(lb)

while her target ending weight still remains (Y)

but the actual ending weight is Y + 3

hence in the second month, Rollie lost 1/3(2/3X + 1/3Y - 3 - Y) + 3

= 2/9X + 1/9Y - 1 - 1/3Y + 3

=  2/9X - 2/9Y + 2

hence by the end of the second month, Rollie's new weight is

(2/3X + 1/3Y - 3) - (2/9X - 2/9Y + 2)

= 2/3X - 2/9X + 1/3Y + 2/9Y - 3 - 2

= 4/9X + 5/9Y - 5  

By the third month, Rollie's starting weight is 4/9X + 5/9Y - 5(lb)

while her target ending weight still remains (Y)

but the actual ending weight is Y + 3

hence in the third month, Rollie lost 1/3(4/9X + 5/9Y - 5 - Y) + 3

= 4/27X + 5/27Y - 5/3 - 1/3Y + 3

= 4/27X - 4/27Y + 4/3 ------------------------- eqn (*)

hence by the end of the third month, Rollie's new weight is

(4/9X + 5/9Y - 5) - (4/27X - 4/27Y + 4/3)

= 4/9X - 4/27X + 5/9Y + 4/27Y - 5 - 4/3

= 8/27X - 19/27Y - 19/3

Hence in three months, Rollie's new weight is 8/27X - 19/27Y - 19/3

To ascertain how much weight Rollie lost in three months, there is need to equate the estimated ending weight to the final weight (Y + 3)

Therefore:

8/27X - 19/27Y - 19/3 = Y + 3

this implies that

8/27X - 19/27Y - Y - 19/3 - 3 = 0

8/27X - 36/27Y -28/3 = 0

Since Y is the target ending weight

the ending weight is generated by solving the equation with respect to Y

36/27Y = 8/27X - 28/3

multiply through by 27/36

Y = 2/9X - 7

Hence weight lost in three months is generated by substituting for Y = 2/9X - 7  in eqn (*)

Since eqn * is 4/27X - 4/27Y + 4/3

the lbs lost in three months is

4/27X - 4/27(2/9X - 7 ) + 4/3

= 4/27X - 8/243X + 28/27 + 4/3

= (32/243)X + 64/27

which in decimal is

(0.132X + 2.37)lbs

The total pounds of weight that will be lost in three months will be (0.132x + 2.37)lbs.

The starting weight is illustrated by x. The target ending weight is illustrated by y.

In the first month, the weight list by Rollie will be 1/3 × (x - y) and her new weight will be:

= 2/3x + 1/3y - 3

In the second month, the starting weight will be 2/3x + 1/3y - 3. The weight lost by the end of the second month will be:

= 1/3 × (2/3x + 1/3y - 3) + 3

= 2/9x - 2/9y + 2

The new weight will be:

= (2/3x + 1/3y - 3) - (2/9x - 2/9y + 2)

= 4/9x + 5/9y - 5

In conclusion, the weight lost in three months will be:

= 4/27x - 4/27(2/9x - 7) + 4/3

= 4/27x - 8/243x + 28/27 + 4/3

= 32/343x + 64/27

= 0.132x + 2.37

In conclusion, the total pounds of weight that will be lost in three months will be (0.132x + 2.37)lbs.

Emily's figurine is 17 inches taller than Chen's figurine

Step-by-step explanation:

Emily and Chen built clay figurines for art class

We need to find how much taller is Emily's figurine than Chen's in inches

To solve this problem we must to change the heights of the two figurines to inch

∵ Emily's figurine is 5' 1" tall ⇒ 5 feet and 1 inch

∵ 1 foot = 12 inches

∴ The height of Emily's figurine = 5(12) + 1

∴ The height of Emily's figurine = 60 + 1

∴ The height of Emily's figurine = 61 inches

∵ Chen's figurine is 3' 8" tall ⇒ 3 feet and 8 inches

∵ 1 foot = 12 inches

∴ The height of Chen's figurine = 3(12) + 8

∴ The height of Chen's figurine = 36 + 8

∴ The height of Chen's figurine = 44 inches

To find how much taller is Emily's figurine than Chen's in inches subtract their heights

∵ The difference between the two figurine = 61 - 44

∴ The difference between the two figurine = 17 inches

∴ Emily's figurine is 17 inches taller than Chen's figurine

Emily's figurine is 17 inches taller than Chen's figurine

Answer:

The theorem states that if a right triangle has two sides equal to a and b, and a hypotenuse equal to c, then a squared plus b squared equals c squared. The hypotenuse of a right triangle is the side opposite the right angle.

Step-by-step explanation:

Answer:

∠Q = 75 °

Step-by-step explanation:

Since PR = PQ then Δ PQR is isosceles and the base angles are congruent, that is

∠R = ∠Q = 2x + 15

The sum of the 3 angles in a triangle = 180°

Sum the 3 angles and equate to 180

2x + 15 + 2x + 15 + x = 180, that is

5x + 30 = 180 ( subtract 30 from both sides )

5x = 150 ( divide both sides by 5 )

x = 30

Hence

∠Q = 2x + 15 = (2 × 30) + 15 = 60 + 15 = 75°

The markup percentage is 45.14%

Step-by-step explanation:

The given is:

We need to find the markup percentage

The markup percentage = [tex]\frac{New-Old}{old}[/tex] × 100%

∵ The selling price of a box of crackers is $1.75

∴ Old = 1.75

∵ You mark the crackers up to $2.54

∴ New = 2.54

- Substitute these values in the rule above

∵ The markup percentage = [tex]\frac{2.54-1.75}{1.75}[/tex] × 100%

∴ The markup percentage = [tex]\frac{0.79}{1.75}[/tex] × 100%

∴ The markup percentage = 0.4514 × 100%

∴ The markup percentage = 45.14%
