Philip wants to enclose his garden using 30 meters of fence. What is the largest interger value area, in square meteres, that he can enclose? What are the dimensions of the rectangular enclosure for his garden?
Answer:
36
Step-by-step explanation:
divide then subtract
The dimensions of the rectangular enclosure for his garden is length of 7.5 m and width of 7.5 m.
Let x represent the length of the garden and y represent the width of the garden.
Perimeter = 2(x + y)
30 = 2(x + y)
x + y = 15
y = 15 - x
Area (A) = length * width
A = xy
A = x(15 - x)
A = 15x - x²
Maximum area is at dA/dx = 0:
dA/dx = 15 - 2x
0 = 15 - 2x
2x = 15
x = 7.5 m
y = 15 - x = 15 - 7.5 = 7.5 m
The dimensions of the rectangular enclosure for his garden is length of 7.5 m and width of 7.5 m.

Davis wants to the grocery store and purchased cans of soup and frozen dinners. Each can of soup has 250 mg of sodium and each frozen dinner has 550 mg of sodium. David Purchased twice as many cans of soup as frozen dinners and they all collectively contain 2100 mg of sodium. Determine the number of cans of soup purchased and the number of frozen dinners purchased.
Answer:
4 cans of soup and 2 frozen dinners.
Step-by-step explanation:
Let the can of soup = x
Let frozen dinner s = y
Davis wants to the grocery store and purchased cans of soup and frozen dinners.
Each can of soup has 250 mg of sodium and each frozen dinner has 550 mg of sodium.
David Purchased twice as many cans of soup as frozen dinners and they all collectively contain 2100 mg of sodium.
x = 2y
Hence:
250x + 550y = 2100
250(2y) + 550y = 2100
500y + 550y = 2100
1050y = 2100
y = 2100/1050
y = 2
Since
x = 2y
x = 2 × 2
x = 4
Hence,
the can of soup = x = 4
Let frozen dinner s = y = 2
Davis bought 4 cans of soup and 2 frozen dinners.

The athlete jogged a distance of 4850 yards in 20 minutes. What is the time needed to cover 9215 yards at the same rate?
Let x be the time needed to cover 9215 yards.
Equation :
Answer :
Answer:
38
Step-by-step explanation:
Make a chart
20 = 4850
? = 9215
9215 / 4850 = 1.9
20 x 1.9 = 38
I don't know it this is right but I hope it helps
Answer:
Equation: 20 / 4850 = x / 9215 Answer: 37.99 minutes
Step-by-step explanation:
(The backslashes are representing a divide symbol, not a fraction)
I don't know what kind of equation you need but the equation I wrote is the one I used to solve this. You must divide the amount of time it took to run the distance which is 20 minutes by the yards jogged which is 4850. That will give you the amount of time it took the athlete to jog one yard which you should then multiply by 9215 yards to find out how much time would be needed to cover that distance. In the equation, if you replace the "x" with the answer (37.99), the equations should be equal.
(I'm really sorry if this doesn't make sense or it's confusing but I hope it helped)
A magic carpet is made with 3 colors of yarn with a ratio of: 5 yards gold : 3.5 yards bronze : 1.5 yards silver When the magic carpet is made with a total of 150 yards of yarn. How much bronze yarn is in the magic carpet?
Step-by-step explanation:
22.5 yards
hope it helps!
The amount of bronze yarn is 52.5 yards in the magic carpet.
What is Ratio?The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.
Given carpet is made with 3 colors of yarn with a ratio of: 5 yards gold : 3.5 yards bronze : 1.5 yards silver
There are 10 pieces of yarn in total. This signifies that 3.5 yards of the carpet are bronze.
To compare this to the 150 meters of total yarn, use the following equation:
⇒ 3.5/10 = x/150
⇒ After that, you cross multiply:
3.5×150 = 10×x or, more simply, 525 = 10x
Then, divide both sides by 10 to get x on its own.
Because 525 /10 = 52.5, x equals 52.5.
This equates to 52.5 yards of silver in the carpet.
Therefore, the amount of bronze yarn is 52.5 yards in the magic carpet.

What is the equation of the line that passes through the point (-6, -7) and
has a slope of o?
Answer:
[tex]y = 0x - 7[/tex]
Step-by-step explanation:
I'm guessing you mean that the slope is 0??
Equation will then look like this
[tex]y = 0x + b[/tex]
to get b insert the point into the equation so y will be replaced by -7 and x will be replaced by -6
[tex] - 7 = 0 \times( - 6) + b[/tex]
[tex]b = - 7[/tex]
Therefore the equation will be
[tex]y = 0x - 7[/tex]

Answer:
X + Y = 1 ------1
X - 2y = 4 ------2
Solving by substitution method
X = 4 + 2y -----3
Putting the value of X in equation 1
4 + 2y + y = 1
4 + 3y = 1
3y = 1 - 4
3y = (-3)
y = (-3) /3
y = (-1)Putting value of y in equation 3
X = 4 + 2(-1)
X = 4 - 2
X = 2

Answer:
The answer looks like C.
Step-by-step explanation:
Combine any like terms on each side of the equation: x-terms with x-terms and constants with constants. Arrange the terms in the same order, usually x-term before constants. If all of the terms in the two expressions are identical, then the two expressions are equivalent. That is how you find which expression is equivalent.
Answer:
C. p^16/q^12
Step-by-step explanation:
The reason why the answer would be p^16/q^12 would be because, that if it is exponents. You always. Always. Subtract or Add depending if its multiplication or subtraction. So p^24-p^8 would be p^16. q^4-q^12 would be q^12.
Therefore, your answer would be p^16/q^12

$1,870.50
$2,101.75
$2,687.50
$2,848.75
Answer:
$2101.75
Step-by-step explanation:
You would start by dividing 215000 by 100 to get 1% then multiply that by 0.87 which is
215000÷100=2150
2150×0.87=1870.5
Then do the same same for the other but switch the numbers so
18500÷100=185
185×1.25=231.25
Then add to get
1870.5+231.25=$2101.75

A relation is defined by the points (1, 4), (3, -1), (-1, -2), and (1, -3).
This relation ( is , is not ) a function because there ( is no x-value,is one x-value,are two x-values) corresponding to multiple y-values.
Answer: is not / is one x-value
Step-by-step explanation:
The relation is not a function because there is one x-value corresponding to multiple y-values.
Why it is not a function?
For a function, each point on the domain is mapped into only one point on the range.
In this relation we can see the points:
(1, 4), (3, -1), (-1, -2), and (1, -3).
Then we can see that the element of the domain "1" is being mapped into two different elements of the range (4, and -3).
Then the relation is not a function because there is one x-value corresponding to multiple y-values.

Answer to #1: £2.50
Sapir bought 60 bags for £3(60) = £180. Then she sells 1/2 of them, or 30 of them, for £5 each, making £150. She sells 1/3 * 60 = 20 of them for £4 each and makes £80 more. There are 10 bags remaining, and Sapir has made £50 profit. She needs to make £25 more, and has 10 more bags to sell. So she just has to sell them for £2.50 each.
