Answer:
(a) He would need 76 feet of fencing
(b) Kevin should buy the packaged box of 90 feet of fencing for $950.
(c) How much does he save?
For every 1 feet of packaged fencing Kevin buys, he saves $1.94 naira.
Step-by-step explanation:
(a) At the outside edge of the pool is a protective fence. How many feet of fencing would be needed to surround the pool area?
From the question, we are told that the swimming pool measures:
14-1/2 feet wide and 23-1/2 feet long.
Perimeter of a fence = 2(L + W)
= 2( 14-1/2 + 23-1/2)feet
= 76 feet
This means he need 76 feet of fencing.
(b) Kevin discovers that he can buy a packaged box of 90 feet of fencing for $950 or he can buy cut-to-order fencing that costs $12.40 per foot. Which type of fencing should he buy?
If : For cut to order fencing
1 foot = $12.40
76 feet =
Cross Multiply
= 76feet × $12.40/1 foot
= $942.4
This means that the cut to order fencing would cost him $942.40
The packaged box of fencing cost $950 for 90 feet of fencing. This is cheaper than the cut to order fencing and he would have extra feet of fencing(14 feet) .
Therefore, Kevin should buy the packaged box of 90 feet of fencing for $950.
How much money does he save?
For the cut to order box
1 feet = $12.40
For the packaged fence,
90 feet = $950
1 feet = x
= 950/90
= $10.555555556
≈ $10.56
Hence, 1 feet of packaged fence = $10.56
Subtracting $10.56 from $12.40
= $12.40 - $10.56
=$ 1.94
Therefore, for every 1 feet of packaged fencing Kevin buys, he saves $1.94 naira.
This means:
1 feet (packaged fence) = $10.56
76 feet = x
= 76 × $10.56
= $802.56
Here's an easy question. Gina bought 2.5 pounds of peaches that cost $1.38 per pound at the grocery store. Amy went to the local farmer’s market and purchased 3.5 pounds of peaches at $0.98 per pound. Who spent more money, and how much more?
A. Gina, $0.20
B. Gina, $0.02
C. Amy, $0.20
D.Amy, $0.02
Answer:
B, Gina, $0.02
Step-by-step explanation:
Per pound is $1.38, so split it in half to get $0.69 for half a pound.
Then you have 1.38 + 1.38 + 0.68 = $3.45 total for Gina.
Per pound is $0.98, if you split that in half you get $0.49 for half a pound.
Add it up, 0.98 + 0.98 + 0.98 + 0.49 = $3.43.
You can see Gina spent more, and then you subtract 3.43 from 3.45 and get $0.02.
Which of the following is not a function?
A{ (0,1), (1,2), (2,3), (3,4)}
B.{(0,2), (1,3), (4,3), (1,2)}
C.{(1,3), (4,2), (2,0), (3,4)}
D.{(1,2), (2,2), (3,2), (4,2)}
Answer:
B. {(0,2), (1,3), (4,3), (1,2)}
Step-by-step explanation:
A relation is not a function if the same input value maps to multiple output values. Essentially, if any x is repeated, it is not a function.
The second set, {(0,2), (1,3), (4,3), (1,2)}, has x-values of 0, 1, 4, 1, so 1 is repeated. It is not a function.

In ΔJKL, \text{m}\angle J = (8x+6)^{\circ}m∠J=(8x+6)
∘
, \text{m}\angle K = (2x+2)^{\circ}m∠K=(2x+2)
∘
, and \text{m}\angle L = (4x+4)^{\circ}m∠L=(4x+4)
∘
. Find \text{m}\angle L.m∠L.
Answer:
The measure of angle L is 52
Step-by-step explanation:
Mathematically, in a triangle, the sum of the angles equal 180
So in this case;
J + K + L = 180
So therefore;
8x + 6 + 2x + 2 + 4x + 4 = 180
8x + 2x + 4x + 6 + 2 + 4 = 180
14x + 12 = 180
14x = 180 -12
14x = 168
x = 168/14
x = 12
So to get the measure of angel L, we simply substitute the value x in the equation for L
From the question, L = 4x + 4
So therefore L = 4(12) + 4 = 48 + 4 = 52
Find the coordinates of the midpoint of segment LP with endpoints: L(4, 2) and P(0, 2)
Step-by-step explanation:
here,
midpoint of line segment LP
=( X1 +X2÷2 , Y1 + Y2÷ 2)
=(4+0÷2 , 2+2 ÷2)
=(4÷2 ,4÷2)
=(2,2)
Therefore the midpoint of segment LP with L (4,2) and P (0,2) = (2 ,2).

Answer:

Step-by-step explanation:
f(x) = x (x^2)
For f(x) = 2x + 1 and g(x) = x2 - 7, find (f+ g)(x).
Answer:
(f + g)(x) = x² + 2x - 6
Step-by-step explanation:
Step 1: Define
f(x) = 2x + 1
g(x) = x² - 7
Step 2: Find (f + g)(x)
(f + g)(x) = 2x + 1 + x² - 7
(f + g)(x) = x² + 2x - 6

Karla tosses a penny 20 times how many times is the penny most likely to land heads up
Answer:
10times
Step-by-step explanation:
there is a 50/50 chance of both 20 divided by 2 is 10
After tossing 20 times a coin probability of getting heads is equals to 10.
What is probability?" Probability of any event is defined as the ratio of total number of favourable outcomes to the total number of outcomes."
Formula used
[tex]Probability =\frac{Number of favourable outcomes}{Total number of oucomes}[/tex]
According to the question,
Number of times coin tossed = 20
When we toss a coin there only two outcomes Head and Tail.
As per the formula,
Probability of head = 1 / 2
Probability of tail = 1 / 2
Therefore,
Probability of getting head when Karla tossed coin 20 times is equals to 20 / 2 = 10 times.
Hence, after tossing a coin 20 times probability of getting heads is equals to 10 times.

Diego pays $4.50 for 3 pound of bananas and 2 pounds of oranges. One pound of oranges costs $0.75 more than one pound of bananas. Let b represent the price per pound of bananas . which equation represents the situation, and what is the price per pound of each fruit?
Answer:
D. 3b + 2(b + 0.75) = 4.50; $0.60 per pound of bananas, $1.35 per pound of oranges
Step-by-step explanation:
Price per pounds of bananas = b
Price per pound of oranges = b + $0.75
Diego buys:
3 pounds of bananas = 3(b) = 3b
2 pounds of oranges = 2(b + 0.75)
Amount paid by Diego is expressed as:
3b + 2(b + 0.75) = 4.50
To find the price per pound of each fruit, use the equation above to find the value of b:
3b + 2b + 1.50 = 4.50
Combine like terms
5b + 1.50 = 4.50
5b + 1.50 - 1.50 = 4.50 - 1.50
5b = 3
5b/5 = 3/5
b = 0.6
Price per pound of banana = b = $0.6
Price per pound of oranges = b + $0.75
Plug in the value of b
= $0.6 + $0.75
= $1.35
