1. Mr. Holloway is a craftsman who makes custom guitars by hand. His last order was for 2 guitars, and it took him 8 weeks to ma

ke them. He receives an order to make 7 guitars.If he makes the guitars at the same rate, how long will it take Mr. Holloway to make the guitars?
a=28
b=7
c=4
d=35
2. Solve for x : 4 x - 7 = 49
a=12
b=56
c=14
d=28
3. Michael ordered a chicken parm sandwich for $8, Xavier and Daniel both got a meatball sub for $7.75, and Tony got a veal parm for $9. Tony just got paid so he said the meal was on him as long as his friends took care of the tip. If they left an 18% tip how much would each of Tony's friends pay if they split it evenly?
a=$32.50
b=$5.85
c=$38.35
d=$1.95
4. Simplify: 5 * (10 * 6 + 9) - 9
a=345
b=336
c=291
d=741

Answer:

1) 28 weeks or A

2) 14 or c

Step-by-step explanation:

1) 8/2= 4

   4 multiplied by 7 = 28

answer is 28

2) 4x-7=49

        add 7 to both sides

    4x=49+7

     4x=56

         divide 56 by 4

    56/4=12

answer is 12

Natalija [7]
     Conditional probability is a measure of probability of an event given that another event has occurred. 
      P ( A\ B ) = P ( A ∩ B ) / P ( B )  -  the conditional probability of A given B
      P ( A ∩ B ) = 0.41;  P ( B ) = 0.59
      P ( A \ B ) = 0.41 / 0.59 = 0.6949152 ≈ 0.69
      Answer:  B ) 0.69

cestrela7 [59]

Answer: E. The population decreased by 11% each year.

Step-by-step explanation: In A, the pollution increases at a constant rate, but in a linear way, in other words in each day, the pollution increases 10 grams; The same goes for C: ice "grows" a few milimeters each day; In D, as volume is calculated by the multiplication of π and its radius, the increase in the volume is still linear. In B, the proportionality is related to the power of the turbine not the growth or decay of it. In E, a population grows or decreases in a form of A=A₀(1±r)^t. In this case: A = A₀ (1-0.11)^t.

In conclusion, the function that better describes an exponential growth or decay is the decrease of a population.

HELP PLS>>> The vector (3, - 7) ) is rotated by an angle of (3pi)/4 radians and then reflected across the y-axis. If th
horsena [70]

Answer:

a \approx -2.826, b \approx 7.072

Step-by-step explanation:

First, the vector must be transformed into its polar form:

r = \sqrt{3^{2}+ (-7)^{2}}

r \approx 7.616

\theta \approx 2\pi - \tan^{-1}\left(\frac{7}{3} \right)

\theta \approx 1.629\pi

Let assume that vector is rotated counterclockwise. The new angle is:

\theta' = \theta + \frac{3\pi}{4}

\theta' = 2.379\pi

Which is coterminal with \theta'' = 0.379\pi. The reflection across y-axis is:

\theta''' = \pi - \theta''

\theta''' = 0.621\pi

The equivalent vector in rectangular coordinates is:

a = 7.616\cdot \cos 0.621\pi

a \approx -2.826

b = 7.616\cdot \sin 0.621\pi

b \approx 7.072
