P varies inversely with x. If P = 7 when x = 8, find the value of P when x = 7. A. 0.125 B. 1 C. 7 D. 8
Step-by-step explanation:
P = 8
Step-by-step explanation:
Given that P varies inversely with x then the equation relating them is
P = \frac{k}{x} ← k is the constant of variation
To find k use the condition P = 7 when x = 8 , then
7 = \frac{k}{8} ( multiply both sides by 8 )
56 = k
P = \frac{56}{x} ← equation of variation
When x = 7 , then
P = \frac{56}{7} = 8

Answer: The walking path around it.
Step-by-step explanation:
Remember the Pythagorean's theorem, for a triangle rectangle with catheti A and B, and with hypotenuse H, we have:
A^2 + B^2 = H^2
or
H = √(A^2 + B^2)
Here, A + B is the total distance for the path, while the hypotenuse is the distance for the bridge
Here we can see that:
A = 1170 ft
B = 520 ft
Then:
H = √( (520 ft)^2 + (1170 ft)^2) = 1280.4 ft
Now, let's compute the costs.
For the bridge, we know that each foot costs $11, then for 1280.4 ft the cost is:
Cost of the bridge = (1280.4)*$11 = $14,084.4
And for the walking path, the cost is $6 per foot, then the total cost of the path is:
Cost of the path = (520 ft + 1170 ft)*$6 = $10,140
We know that the bridge is preferred if it is within the range of $1500 for the path's cost.
This range is:
($10,140 - $1,500, $10,140 + $1,500) = ($8,640, $11,640)
Here we can see that the cost of the bridge does not belong to this range, (is higher) so the option we should recommend is the walking path around.

The sum of two numbers is 48.if the smaller number is subtracted from the larger the difference is 12 find the number
Answer:
18
Step-by-step explanation:
30 + 18 = 48
30 - 18 = 12
Both true, so our solution is correct.
The value of the larger number is 30 and the value of the smaller number is 18.
What is a number system?A numeral system is a writing system for expressing numbers; that is, a mathematical notation for representing numbers of a given set in a consistent manner using digits or other symbols. In different numeral systems, the same sequence of symbols can represent different numbers.
Given that the sum of two numbers is 48. if the smaller number is subtracted from the larger the difference is 12. The two numbers will be calculated as,
x + y = 48
x - y = 12
________
2x = 60
x = 30
y = 30 - 12
y = 18
Therefore, the value of the larger number is 30 and the value of the smaller number is 18.

Answer:
(n + 1)(5m + 4)
Step-by-step explanation:
Given
5mn + 5m + 4n + 4 ( factor the first/second terms and the third/fourth terms )
= 5m(n + 1) + 4(n + 1) ← factor out (n + 1) from each term

Can someone actually help me with this
Answer: X = 30*
All circles = 360*
we can subtract 260 from that because we know the length of one so we know the other is 130.
We are then left with only 100 and we know the two sides are equivalent so 100 / 2 = 50
Identify the 31st term of an arithmetic sequence where a1 = 26 and a22 = −226.
−334
−274
−284
−346
Answer:
a31 = -334
Step-by-step explanation:
Given:
a1 = 26
a22 = -226
Find:
a31
Computation:
a22 = a + 21d
-226 = 26 + 21d
d = -12
a31 = a + 30d
a31 = 26 + 30(-12)
a31 = 26 - 360
a31 = -334
a1 = 26 and a22 = −226.

Troy drew the diagram below. The inner circle has a radius of 2 units, and the outer circle has a radius of 5 units. Troy says the two circles are similar.
Which statement best explains whether Troy is correct, and why?
He is correct because the inner circle is a dilation of the outer circle.
O
He is correct because the inner circle has the same center as the outer circle.
O
He is not correct because the inner circle's radius is less than the outer circle's radius.
He is not correct because the inner circle's radius is not half of the outer circle's radius.
o
Answer:A he is correct because the inner circle is a dilation of the outer circle
Step-by-step explanation: just did the test
The statement "He is correct because the inner circle is a dilation of the outer circle" is the best explanation.
What is dilation?Dilation is the process of modifying the size of an item or form by reducing or expanding its dimensions according to specific scaling variables.
The radius of the inner circle is 2 units, while the radius of the outer circle is 5 units.
Since dilations provide similar figures because multiplying by the scale factor yields proportionate sides while keeping the angle measure and form constant.
Troy is accurate if he claims the two circles are similar.
Hence, the statement (A) "He is correct because the inner circle is a dilation of the outer circle" is the best explanation.

Which of these strategies would eliminate a variable in
the system of equations?
8x + 8y = 2
8x + 5y = 1
Answer:x = -1 / 12
Step-by-step explanation: am i right??
8x + 8y = 2 -------(1)
8x + 5y = 1 -------(2)
subtract equation (2) from equation (1)
The 8x will be eliminated, leaving us with;
3y = 1
Divide bothside of the equation by 3
y = 1/3
substituting y = 1/3 in equation (1)
8x + 8y = 2
8x + 8(1/3) = 2
8x + 8/3 = 2
subtract 8/3 from both-side
8x + 8/3 -8/3 = 2 -8/3
8x = 2 - 8/3
8x = 6 - 8 / 3
8x = - 2/3
Divide both-side of the equation by 8
8x / 8 = -2/3 ÷ 8
x = -2/3 × 1/8
x = -1 / 12
