find the measure of the line segment TV​

Answer:

A) 5+3p ≥ 30

Step-by-step explanation:

The 5+3p has to be greater than 30 to move on to the next round. The student scored 5 points in the first round and since the other 3 rounds he scored the same amount of points, your equation would be 5+3p ≥ 30 :)

If you were to solve this, you would subtract 5 from both sides to find that 3p≥ 25. Divide 25 by 3 to find out that Steward needed to score at least 9 points in each of rounds 2,3, and 4, so a possible solution could be that he earned 5 points in round 1, 9 in round 2, 9 in round 3, and 9 in round 4 for a total of 32, which is enough to qualify for the final round :)

Answer:

2.1 gallons

Step-by-step explanation:

Let V = volume of 20 % hydrogen peroxide = 5 gallons, V₁ = volume of 30 % hydrogen peroxide and V₃ = volume of 23 % hydrogen peroxide. So the final volume is V + V₁ = V₂

V₁ + 5 = V₂  (1)

Also, since quantity = concentration × volume,

Let Q = quantity of 20% volume hydrogen peroxide = 0.2V, Q₁ =  quantity of 20% volume hydrogen peroxide = 0.3V₁ and Q₂ = quantity of 23% volume hydrogen peroxide = 0.23V₂

So, 0.2V + 0.3V₁ = 0.23V₂

0.2 × 5 + 0.3V₁ = 0.23V₂

1 + 0.3V₁ = 0.23V₂

0.3V₁ - 0.23V₂ = -1  (2)

substituting equation (1) into (2), we have

0.3V₁ - 0.23(V₁ + 5) = -1

expanding the brackets, we have

0.3V₁ - 0.23V₁ + -0.23 × 5 = -1

0.07V₁ - 1.15 = -1

adding 1.15 to both sides, we have

0.07V₁ = -1 + 1.15

0.07V₁ = 0.15

dividing both sides by 0.07, we have

V₁ = 0.15/0.07

= 2.143 gallons

≅ 2.1 gallons to the nearest tenth

So, we need 2.1 gallons of 30 % hydrogen peroxide to obtain a mixture that is 23 % hydrogen peroxide.

Answer:

T=29.95a + 13.95c

Step-by-step explanation:

For this equation let a=amount of adult tickets, c=amount of children tickets, and T=the total cost. Since each adult ticket costs 29.95 dollars that needs to be multiplied by the number of adult tickets to see how much was spent on adults, the same goes for the price and number of children tickets. Finally, both of those totals need to be added together to see how much is spent overall for all of the guests.

Answer:

If the use the method ''Add -5 to both sides, then multiply both sides by -2/7'', we can get the value n = 6.

Thus, the correct option is 'C'.

Step-by-step explanation:

Given the equation

[tex]-\frac{7}{2}n+5=-16[/tex]

Let me solve this using the correct method

[tex]-\frac{7}{2}n+5=-16[/tex]

Add -5 to both sides

[tex]-\frac{7}{2}n+5+\left(-5\right)=-16+\left(-5\right)[/tex]

simplify

[tex]-\frac{7}{2}n=-21[/tex]

Multiply both sides by -2/7

[tex]-\frac{7}{2}n\times -\frac{2}{7}=-21\times -\frac{2}{7}[/tex]

simplify

[tex]n=6[/tex]

Therefore, if the use the method ''Add -5 to both sides, then multiply both sides by -2/7'', we can get the value n = 6.

Thus, the correct option is 'C'.

Answer:

  A.  (x² -y²)² +(2xy)² = (x² +y²)²

Step-by-step explanation:

As is often the case with problems like this, the correct answer (A) is the only answer that is actually a true equation.

Choices B, C, D are only true if x or y is zero--a violation of the given condition that they are positive integers.

Answer:

Option C: 11 is the correct answer.

Step-by-step explanation:

Given that:

Length of base of isosceles triangle = b =  x

The length of leg of triangle = a = 3x-7

Perimeter of triangle = 63

Perimeter of an isosceles triangle is given by

Perimeter = 2a + b

Putting values in the formula

63 = 2(3x-7) + x

63 = 6x-14+x

63 = 7x-14

63+14=7x-14+14

77=7x

7x=77

Dividing both sides by 7

[tex]\frac{7x}{7}=\frac{77}{7}\\x=11[/tex]

The value of x is 11.

Hence,

Option C: 11 is the correct answer.

Answer:

1238.9

Step-by-step explanation:

The volume of pyramid with square a square base is 1239 [tex]inch^{3}[/tex]

A three-dimensional geometric shape having a square base and four triangular faces/sides that meet at a single point (called vertex) is called a square pyramid

We have

Side length of base(L) = 14.7 inch

Height of pyramid(H) = 17.2 inch

Given ,Base is a square then

length=width(w)=14.7 inch

We know the formula of volume of pyramid = 1/3(L×W×H)

                                                                         = 1/3 (14.7 × 14.7 × 17.2)

                                                                         = 1/3 × 3716.748

                                                                         = 1238.916

                                                                        = 1239 [tex]inch^{3}[/tex]

Hence, The volume of pyramid is 1239 [tex]inch^{3}[/tex]

Answer:

The ordered pair (-6, -1) is the only solution.

Step-by-step explanation:

-6x + y = 35

Let's plug in the points.

(-1, -7) --> -6(-1) - 7 = 6 - 7 = -1 which does not equal 35

(-6, -1) --> -6(-6) -1 = 35

(-1, -6) --> -6(-1) - 6 = 0 which does not equal 35

(-7, -1) --> -6(-7) - 1 = 41 which does not equal 35

The average rate of change of g(x) over the interval [2, 8] is given by

(g (8) - g (2)) / (8 - 2)

In other words, it's the slope of the line through the points (2, g (2)) and (8, g (8)).

Use the definition of the function to evaluate it at the points in the numerator:

• 8 ≥ 4, so using the second piece, g (8) = -0.5(8) + 8 = 4

• 2 < 4, so g (2) = 5(2) + 1 = 11

Then the average rate of change is

(g (8) - g (2)) / (8 - 2) = (4 - 11) / 6 = -7/6

Answer:

The test statistics is  [tex]z = 2.47[/tex]

Step-by-step explanation:

From the question we are told that

    The  sample size is  n =  191 \  buses

     The sample mean is  [tex]\= x = 96 700 \ miles[/tex]

    The population standard deviation is  [tex]\sigma = 37 500 \ miles[/tex]

The null hypothesis is  [tex]H_o : \mu = 90 000[/tex]

The alternative hypothesis is  [tex]H_a : \mu > 90 000[/tex]

Generally the test statistics is mathematically represented as

         [tex]z = \frac{\= x - \mu }{ \frac{\sigma }{\sqrt{n} } }[/tex]

=>      [tex]z = \frac{96700 - 90 000 }{ \frac{37500}{\sqrt{191} } }[/tex]

Answer:

The probability, to the nearest 10th of a percent, that both marbles drawn will be red is 28.5%

Step-by-step explanation:

Number of red marbles = 4

Number of blue marbles = 8

Number of Green marbles = 2

Total number of marbles = 4+8+2 =14

We need to find the probability, to the nearest 10th of a percent, that both marbles drawn will be red?

The formula used will be: [tex]Probability=\frac{Number\:of\:favourable\:outcomes}{Number\:of\;possible\:outcomes}\\[/tex]

In our case, Number of favourable outcomes = 4 (as red marbles are drawn)

Number of possible outcome = 14 (Total number of marbles)

The probability will be:

[tex]Probability=\frac{Number\:of\:favourable\:outcomes}{Number\:of\;possible\:outcomes}\\\\Probability=\frac{4}{14}\\ Probability=0.2857\\[/tex]

Now, calculating nearest 10th of a percent

[tex]Probability = 0.2857*100\\Probability=28.5%[/tex]

So, the probability, to the nearest 10th of a percent, that both marbles drawn will be red is 28.5%

Answer:

Ahmed earned £198.00 on that weekend.

Step-by-step explanation:

Given that:

Normal hourly pay = £12.00

Overtime pay = [tex]1\frac{1}{4}[/tex] of normal rate

Overtime pay per hour = [tex]\frac{5}{4}*12[/tex]

Overtime pay per hour = £15.00

Hours worked on Saturday = 9 hours

Amount earned on Saturday = 9*12 = £108.00

Hours worked on Sunday = 6 hours

Amount earned on Sunday = 6*15 = £90.00

Total amount earned on weekend = 108+90 = £198.00

Hence,

Ahmed earned £198.00 on that weekend.
