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

Sean wants to spend (example) $100 on clothing and he wants to purchase
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

Step-by-step explanation:
solve for x.
a) 9[tex]9^{3x+4}[/tex] = [tex]27^{4x+3}[/tex]
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

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.

Answer:
Smallest integer: 20
Middle integer: 22
Largest integer: 24
Step-by-step explanation:
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
-6 -6
