Which expression is equivalent to
Answer:
The second option
Step-by-step explanation:
First, simplify the bracket
[tex] \frac{4r {}^{3} s {}^{2} t {}^{4} }{2r {}^{4} st {}^{6} } [/tex]
Apply Quotient of Powers
[tex]2 {r}^{ - 1} s {t}^{ - 2} [/tex]
Which equals
[tex] \frac{2s}{rt {}^{2} } [/tex]
Raise this to the fifth power
[tex] \frac{32s {}^{5} }{ {r}^{5} t {}^{10} } [/tex]
Multiply by the outsides numbers(5^r^6 and t^4
[tex] \frac{160 {}^{} r {}^{6}s {}^{5} t {}^{4} }{r {}^{5} t {}^{10} } [/tex]
[tex]160r {}^{5} t {}^{ - 6} [/tex]

4) 2x(x+y)-(4x+2y)(3x-y)
Answer:
-10x² + 4xy - 2y²
Step-by-step explanation:
2x(x + y) - (4x + 2y)(3x - y)
= 2x² + 2xy - 12x² - 4xy + 6xy - 2y²
= 2x² - 12x² + 2xy - 4xy + 6xy - 2y²
= -10x² + 4xy - 2y²

Identify the equivalent expression below that demonstrates commutative property.
Answer:
9*(40)
Step-by-step explanation:
9*(10*4)

Help me please! Am horrible at math.
Answer:
Step-by-step explanation:
For a. the 14.7 represents the pressure that the air puts on you all the time.
For b. the d represents the depth you go under the surface of the water.
For c. we have to solve p(d) when d = 8:
p(8) = 14.7 + 0.445(8) so
p(8) = 14.7 + 3.56 and
p(8) = 18.26 psi
John's Coffee Shop makes a blend that is a mixture of two types of coffee. Type A coffee costs John $5.95 per pound, and type B coffee costs $4.65 per pound. This month's blend used three times as many pounds of type B coffee as type A, for a total cost of $656.70. How many pounds of type A coffee were used?
Answer:
Let x = the number of lbs of Type A coffee.
We know that this month's blend used 3 times as many pounds of type B coffee as type A coffee.
Total lbs of coffee = x + 3x
The total cost then is:
($ cost for Type A)(x) + ($ cost for Type B)(3x) = $717.60
$5.65x + $4.25(3x) = $717.60
$5.65x + $12.75x = $717.60
$18.40x = $717.60
x = 39 lbs
What is the solution to the equation 5 + b = 18?
F b= 5
H b= 13
Gb=8
Jb= 23
Answer:
H) B= 13
Step-by-step explanation:
5 + b = 18
F) 5 + 5 = 10 so not equal to 18. It is not a solution
H) 5 + 13 = 18 it's equal . so it is the solution
G) 5 + 8 = 13 so not equal to 18. It is not a solution
J) 5 + 23 = 28 so not equal to 18. It is not a solution
13 is the answer
Step-by-step explanation:
5+b=18
b=18-5
b=13.

write 2.5 repeating as a mixed number in simplest form.
Answer:
2 5/9
Step-by-step explanation:
2.5 repeating is 2 5/9 as a fraction (mixed number) or 23/9 (fraction)
The repeating decimal 2.5 can be written as the mixed number 2 5/9 in simplest form.
Here, we have,
To convert the repeating decimal 2.5 to a mixed number in simplest form, we can follow these steps:
Step 1:
Let's assume x = 2.5
Step 2:
Multiply both sides of the equation by 10 to shift the decimal point one place to the right: 10x = 25.5
Step 3:
Subtract the original equation from the one obtained in Step 2 to eliminate the repeating part:
10x - x = 25.5- 2.5
9x = 23 (since the repeating part subtracts to zero).
Step 4: Solve for x by dividing both sides by 9:
x = 23 / 9.
Step 5: Express the fraction 23/9 as a mixed number:
23 ÷ 9 = 2 remainder 5.
Therefore, x = 2 remainder 5/9.
so, we get,
Thus, the repeating decimal 2.5 can be written as the mixed number 2 5/9 in simplest form.

What was Veronica's speed if she drove 475 miles in 6 1/4 hours?
Answer: 76 mph
Step-by-step explanation: speed is distance divided by time so 475 : 6.25 = 76 (mph)
Answer:
76 mph
Step-by-step explanation:
To find the answer, you would divide the miles she drove: 475 by the amount of time it took to get there: 6 1/4 hours. Convert the fraction to a decimal: 1/4= .25 so your problem would look like this...
475 / 6.25 = 76

Diana works in a building that is 130 feet tall. She is outside, looking up at the building at an angle of 37° from her feet to the top of the building.
Let x be her initial distance from the building, then tan 37 = 130/x
x = 130/ tan 37 = 130/0.7536 = 172.5 feet
Let y be her distance from the building after moving forward, then
tan 40 = 130/y
y = 130/tan 40 = 130/0.8391 = 154.9
After moving forward, she is 172.5 - 154.9 = 17.6 ft closer.
Answer:
172.5 feet to the nearest tenth.
Step-by-step explanation:
I guess you need the distance between Diana and the bottom of the building.
tan 37 = 130 / d where d is this distance
d * tan 37 = 130
d = 130 / rtan 37
= 172.5158 feet
