A. 9B. 9 Square Root Of 2C. 18D. 18 Square Root Of 2

Answers

Answer 1

Answer:

B

Step-by-step explanation:

We are given a right triangle with angles 45, 90, and 45

With this type of right triangle, the ratio of the sides are 1:1:square root of 2

We are also given that the hypotenuse is 18

This means that the sides are in the ratio of x:x:x(square root of 2)

Since 18 is the hypotenuse, we can form the equation of-

18 = x(square root of 2)

18/(square root of 2)=x

x= 9 square root of 2

since y=x, y= 9 square root of 2

Step-by-step explanation:

 X+73°+75°=180° (interior angles of a triangle adopts to 180°)

 X=180°-148°

 X=32°

 32°+Y+26°=180°(interior angles of a triangle adopts to 180°)

 Y=180°-58°

-12+8x

distribute the 6 to the 3x and the 18

-12+8x = 18x+18

subtract 8x from both sides

subtract 18 from both sides

-30= 10x

6 additional items for his wardrobe. Each pair of pants costs $20 and each shirt costs $15.
Show the solution graphically.

Point (2, 4)

Answers

Answer:

Step-by-step explanation:

Let x be the number of pants and y be the number of shirts

x + y = 6

20x + 15y = 100

multiply the first equation by -20

-20x -20y = -120

20x + 15y = 100

subtract the equations

-5y = -20

y = 4

replace y in equation 1

x + 4 = 6

x = 2

b) [tex]4^{3x}[/tex] = [tex]2^{x+1}[/tex]

(include steps pleez)

Answers

Answer:

Question a)

[tex]9^{3x+4}=27^{4x+3}[/tex]

[tex]x=-0.166[/tex]

Question b)

[tex]4^{3x}=2^{x+1}[/tex]

[tex]x=0.2[/tex]

Step-by-step explanation:

Question a)

Given the expression

[tex]9^{3x+4}=27^{4x+3}[/tex]

Taking log on both sides

[tex]log\left(9^{3x+4}\right)=log\left(27^{4x+3}\right)[/tex]

[tex]\left(3x+4\right)\cdot \left(log\left(9\right)\right)\:=\left(4x+3\right)\cdot \left(log\left(27\right)\right)[/tex]

[tex]3x+4=\left(\frac{log\left(27\right)}{log\left(9\right)}\right)\cdot \left(4x+3\right)[/tex]

[tex]3x+4=1.5\times \left(4x+3\right)[/tex]

[tex]3x+4=6x+4.5[/tex]

[tex]3x=6x+0.5[/tex]

[tex]\frac{-3x}{-3}=\frac{0.5}{-3}[/tex]

[tex]x=-0.166[/tex]

Therefore, the value of x:

[tex]x=-0.166[/tex]

Question b)

Similarly, we can solve the 'b' expression

Given the expression

[tex]4^{3x}=2^{x+1}[/tex]

Taking log on both sides

[tex]log\left(4^{3x}\right)=log\left(2^{x+1}\right)[/tex]

[tex]3x\cdot \left(log\left(4\right)\right)=\left(x+1\right)\cdot \left(log\left(2\right)\right)[/tex]

[tex]3x=\left(\frac{log\left(2\right)}{log\left(4\right)}\right)\cdot \left(x+1\right)[/tex]

[tex]3x=0.5\times \left(x+1\right)[/tex]

[tex]3x=0.5x+0.5[/tex]

[tex]2.5x=0.5[/tex]

Divide both sides by 2.5

[tex]\frac{2.5x}{2.5}=\frac{0.5}{2.5}[/tex]

[tex]x=0.2[/tex]

Therefore, the value of x = 0.2

Denote the smallest integer as "x"; hence the next integer will be "x + 2", and the third will be "x + 4".

Using the information, set up an equation:

x + x + 2 + x + 4 = 66

Simplify

x + x + 2 + x + 4 = 66

3x + 6 = 66

Inverse operations

3x + 6 = 66

Suppose that you need to buy some chicken for dinner tonight. You found an ad showing that a store across town has chicken on sale for $2.99 per pound. Your usual neighborhood store sells the same chicken for $3.79 per pound. You are considering whether it is worth the drive to purchase the chicken from the store across town. Information you will need:________
A. You need to purchase 3 pounds of chicken
B. Your neighborhood store is 2.1 miles away and takes about 8 minutes to get there
C. The store across town is 8.6 miles away and takes about 24 minutes to get there
D. Your car averages about 22 miles per gallon in the city Gas is $3.05 per gallon

Answers

Answer:

C). The store across town is 8.6 miles away and takes about 24 minutes to get there.

D). Your car averages about 22 miles per gallon in the city Gas is $3.05 per gallon.

Step-by-step explanation:

The information regarding the distance of the store across town from the house, the time required to reach there, the average of the car, and the cost of gas per gallon would assist in calculating if the extra drive is worth buying chicken from the city store.

Cost of chicken in the city store - $2.99 per pound

Average of the car in 1 gallon = 22miles

so, the average of the car in 1 mile = 1/22

Cost of traveling 8.6miles = 8/22 * $3.05

                                           = 24.40/22

Additional cost = $ 1.109

Total cost of buying chicken from the city store = $2.99 + $1.10

                                                                                = $4.09

Hence, it is not worth to buy the chicken from the store across the town as it is costlier in comparison to $3.79 in nearby store.
