Answer:
129
Step-by-step explanation:
1,923 divided by 15 is 128.2
however you can't have 128.2 rows, so you need an extra row to accommodate for the leftover bushes
so 129
The inequality that will determine the number of months, x, that are required for the second phone to be less expensive is . The solution to the inequality is . Sal's mother would have to keep the second cell phone plan for at least months in order for it to be less expensive.
Question:
Sal is trying to determine which cell phone and service plan to buy for his mother. The first phone costs $100 and $55 per month for unlimited usage. The second phone costs $150 and $51 per month for unlimited usage.
The inequality that will determine the number of months, x, that are required for the second phone to be less expensive is .
The solution to the inequality is .
Sal’s mother would have to keep the second cell phone plan for at least months in order for it to be less expensive.
Answer:
a. [tex]150 + 51x < 100 + 55x[/tex]
b. [tex]x > 12.5[/tex]
c. At least 13 months
Step-by-step explanation:
Given
First Phone;
[tex]Cost = \$100[/tex]
[tex]Additional = \$55[/tex] (monthly)
Second Phone;
[tex]Cost = \$150[/tex]
[tex]Additional = \$51[/tex] (monthly)
Solving (a): The inequality
Represent the number of months with x
The first phone is expressed as:
[tex]100 + 55x[/tex]
The second phone is expressed as:
[tex]150 + 51x[/tex]
For the second to be less expensive that the first, the inequality is:
[tex]150 + 51x < 100 + 55x[/tex]
Solving (b): Inequality Solution
[tex]150 + 51x < 100 + 55x[/tex]
Collect Like Terms
[tex]51x-55x<100 - 150[/tex]
[tex]-4x<-50[/tex]
Solve for x
[tex]x > -50/-4[/tex]
[tex]x > 12.5[/tex]
Solving (c): Interpret the solution in (b)
[tex]x > 12.5[/tex] implies 13, 14, 15....
Hence, She'll keep the second phone for a period of at least 13 months

Ned is riding his bike from his house to the park, both of which are on the same straight road. On his way, he stops at a store, which is 47 of the way to the park, and then bikes the remaining 0.6 mile to the park. What is the distance between Ned's home and the park?
Complete question :
Ned is riding his bike from his house to the park, both of which are on the same straight road. On his way, he stops at a store, which is 4/7 of the way to the park, and then bikes the remaining 0.6 mile to the park. What is the distance between Ned's home and the park?
Answer:
1.4 miles
Step-by-step explanation:
Given that :
Ned's home and park are on the same straight road :
Store where Ned stopped is 4/7 of the way to the park
Bikes the remaining 0.6 miles to the park
Hence after traveling 4/7 of the distance, distance to park is 0.6 miles
Hence, 1 - 4/7 = 3/7
Hence, 3/7 of the way = 0.6 miles
If 3/7 = 0.6 miles
Then, 1 = x
Cross multiply
3/7 x = 0.6
3x = 4.2
x = 4.2 / 3
x = 1.4 miles
The distance from Ned's home to park is 1.4 miles
The distance between Ned's home and the park is 1.4 miles.
Ned is riding his bike from his house to the park, both of which are on the same straight road.
At some point between the way to the park, he covered [tex]\dfrac{4}{7}[/tex] of total distance and the destiny is still remained by 0.6 mile.
The fraction of the distance yet to be covered is,
[tex]\begin{aligned}\rm{Remaining\;distance}&=1-\dfrac{4}{7}\\&=\dfrac{7-4}{7}\\&=\dfrac{3}{7} \end{aligned}[/tex]
Now, the remaining distance is given that is 0.6 mile.
Therefore,
[tex]\begin{aligned}\dfrac{3}{7} \times \rm{Total \;distance}&=0.6\\\rm{Total \;distance}&=1.4\;\rm{miles} \end{aligned}[/tex]
Thus, the distance between Ned's home and the park is 1.4 miles.

Which ordered pair is the solution to the system of equations? {−3x+4y=−20y=x−4 (−4, −8) (4, 8) (−2, −6) (0, −5)
Answer:
Step-by-step explanation:
-3x + 4y = -20
y = x - 4
Put the second equation into the first equation in place of y.
-3x + 4 (x - 4) = -20
Multiply everything in the parenthesis by 4.
-3x + 4x - 16 = -20
Combine like terms.
x - 16 = -20
Add 16 to both sides.
x = -4
Put this into the second equation in place of x.
y = -4 - 4
y = -8
Your solution set is (-4,-8).

The value of x in the expression is,
⇒ x = 0
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We have to given that;
The expression is,
⇒ 2 (x - 3) + 9 = 3 (x + 1) + x
Now, We can simplify the expression as;
⇒ 2 (x - 3) + 9 = 3 (x + 1) + x
⇒ 2x - 6 + 9 = 3x + 3 + x
⇒ 2x + 3 = 4x + 3
⇒ 4x - 2x = 3 - 3
⇒ 2x = 0
⇒ x = 0
Thus, The value of x in the expression is,
⇒ x = 0

Write an equation of a line that is (a) parallel to the given line and (b)
perpendicular to the given line.
can you answer 7 too ?
Answer:
for question 7 : I think it is no
Step-by-step explanation:
if you plot the points on a quick rough sketch you will find that none of the coordinates are on the same line (which they would have to be for a straight line). No points in those 3 coordinates are the same so the there cannot be two points on the same x or y coordiante therefore there is no right-angles triangle.
If you plot the points roughly there will not be two perpendicular lines so there is no right-angles triangle.
sorry I realise this is confusing :(
Also for Question 5:
Parallel should be anything y= for example, y=6
Perpendicular should be anything x= for example x=6 as y=7 is a horizontal line and x=6 is a vertical line. Y=6 would be parallel because y=(any number with no gradient e.g. 1,2,3,4,etc.) is horizontal.

Answer:
Area = 76[tex]m^{2}[/tex]
Step-by-step explanation:
you can cut into two rectangles
first one:
top and bottom sides = 4m
two sides = 9m
Area = b*h = 9m * 4m = 36 [tex]m^{2}[/tex]
second one
top and bottom sides = 8m
two sides = 14m - 9m = 5m
Area = b*h = 8m * 5m = 40[tex]m^{2}[/tex]
Now add both rectangle areas for the total shaded Area = 36 + 40 = 76[tex]m^{2}[/tex]

The Marine Discovery Aquarium sells ocean-themed cookies in their gift shop. Last month, they sold 65 shark cookies and 85 clown fish cookies. The cookies were so popular that they want to order more cookies this month. They plan to order 170 clown fish cookies this month. If they keep the same ratio, how many shark cookies should they order this month?
Answer: 130 shark cookies.
Step-by-step explanation: If you divided 170 clown fidh cookies by 85 clown fish cookies you get 2. So same as 85 times 2. Then do the same with the shark cookies. 65 times 2, that equals 130.
