What is the answer for number 12

Brad is 3 years older than Francis. The product of their ages is 154. Determine their ages.

Age of Bard× Age of Francis=154

Let's split 3x into +14x and -11x

So we aren't taking ages in negetive

As we know in starting we have take x as Financis age

We know Brad is 3 years older than Francis

With regards!

Answer:

[tex]Width: \frac{3in}{8ft} = \frac{5in}{x} (cross multiply)[/tex]

   = [tex]40[/tex] ÷3 ≈ 13.3ft

[tex]Width: \frac {3in}{8ft} = \frac{6.5in}{x}[/tex]

   = 17.3

[tex]A=e[/tex] × [tex]w[/tex]

   [tex]= 13.3[/tex] × [tex]17.3[/tex] ≈ [tex]230.09[/tex] ≈ [tex]230.1[/tex]

Answer:

Hare wins the race

Step-by-step explanation:

Length of track = 100 m

Let t represent the number of seconds in completing the race.

Speed of tortoise = 0.7 m/s

Distance covered by tortoise in t seconds = Speed \times time = 0.7t

We are given that The tortoise negotiated a 60-meter head start with the hare.

So, Distance covered by tortoise in t seconds = 60+0.7t

Speed of hare = 3.6 m/s

Distance covered by hare in t seconds = 3.6 t

Now

3.6t = 100

[tex]t=\frac{100}{3.6}[/tex]

t=27.77

60+0.7t=100

[tex]t=\frac{100-60}{0.7}[/tex]

t=57.14

So, Hare took less time

So, Hare wins the race

Step-by-step explanation:

Statistical significance level is the probability of rejecting the null hypothesis. Statistical significance at the 0.05 level is the standard level for rejecting the null hypothesis.

A significance of 0.01 shows that there is strong evidence to conclude that the null hypothesis is not true. A 0.05 significance is the most used level while 0.01 is used when multiple tests are conducted or when the researcher is not so sure if the null hypothesis should be rejected. It increases the amount of evidence required to prove the null hypothesis and it also reduces the possibility of obtaining a false positive.

Determine fraction of each teacher

Each fraction is calculated by dividing total fraction by number of teachers as follows:

[tex]Each = \frac{Fraction}{Teachers}[/tex]

[tex]Each = \frac{4}{5}/3[/tex]

[tex]Each = \frac{4}{5} * \frac{1}{3}[/tex]

Answer:

  90°

Step-by-step explanation:

The lines of reflection make right angles with each other, so the angle made with the reflected points will be a right angle.

  m∠BAC = 90°

Answer:

If you are referring to the angle of the polygon, than it is the same, if you are referring to the angle between the initial and final point about the origin, than it's a right angle. If there is a point(x,y) rotated about the origin(0,0), then the new point will be (y,-x).

Answer:

study writers of pagan Rome

Step-by-step explanation:

Petrarch believed Christian scholars should study writers of pagan Rome. Option (b) is correct.

A writer is someone who writes books, articles, stories, etc., sometimes as a job or a vocation.

Francesco Petrarca, often known as Petrarch, was an Italian philosopher, poet, and one of the first Humanists. He lived from July 20, 1304, to July 19, 1374. The 14th-century Renaissance is frequently regarded with having started as a result of Petrarch's rediscovery of Cicero's letters. Humanism is frequently credited with having its roots in Petrarch. During the Renaissance, Petrarch's sonnets were appreciated, emulated, and used as a template for lyrical poetry all over Europe. Based on Petrarch's writings, Pietro Bembo developed the framework for the modern Italian language in the 16th century.

Therefore, Option (b) is correct. Petrarch believed Christian scholars should study writers of pagan Rome.

Answer:

[tex]y=-2^{(x+2)}+1[/tex]

Step-by-step explanation:

Equation of the parent function of the graph attached is,

y = [tex]2^{x}[/tex]

Let the equation of the transformed function function shown in the graph be,

y = a(2ˣ) + b

Now we will find the values of a and b by substituting the points lying on the curve.

For (-2, 0),

0 = a(2⁻²) + b

[tex]\frac{a}{4}+b=0[/tex] ------(1)

For (0, -3),

-3 = a(2⁰) + b

a + b = -3 --------(2)

Subtract equation (1) from equation (2),

(a + b) - ([tex]\frac{a}{4}+b[/tex]) = 0 + 3

[tex]\frac{3a}{4}=3[/tex]

a = -4

From equation (2),

-4 + b = -3

b = 1

Therefore, equation of the transformed function will be,

[tex]y=-4(2^x)+1[/tex]

[tex]y=-2^{2}(2^x)+1[/tex]

[tex]y=-2^{(x+2)}+1[/tex]

Graph transformation is the process by which an existing graph is modified to produce a variation of the proceeding graph.

Equation of transformed graph is, [tex]y=-2^{x+2}+1[/tex]

Here,  equation of original graph is given, [tex]y=2^{x}[/tex]

Let us consider, equation of transformed graph is,  [tex]y=m(2^{x} )+n[/tex]

Since, given graph passing through points (-2,0) and (0,-3)

Substituting above points into equation.

We get two equation,

                                      m +4n = 0

                                     m + n = -3

After solving, we get   m= -4 and  n = 1

So, equation becomes  [tex]y=-2^{x+2}+1[/tex]

Answer:

The magnitude of the velocity will be 60 m/s.

The distance covered is 3,600 m

Step-by-step explanation:

Constant Acceleration Motion

It's known as a type of motion in which the velocity of an object changes by an equal amount in every equal period of time.

If a is the constant acceleration, vo is the initial speed, vf the final speed, and t the time, the following relation applies:

[tex]v_f=v_o+at[/tex]

The distance traveled by the object is calculated as:

[tex]\displaystyle x=v_o.t+\frac{a.t^2}{2}[/tex]

The bus starts from rest, i.e. vo=0, the acceleration is a=0.5 m/s^2. The magnitude of the velocity at t=2 minutes = 120 seconds is:

[tex]v_f=0+0.5\cdot 120=60 \ m/s[/tex]

The magnitude of the velocity will be 60 m/s.

The distance covered during that time is:

[tex]\displaystyle x=0+\frac{0.5\cdot 120^2}{2}[/tex]

[tex]\displaystyle x=\frac{7,200}{2}[/tex]

x = 3,600 m

The distance covered is 3,600 m
