Answer:
c ≥ 56 is the REQUIRED INEQUALITY.
Step-by-step explanation:
Here, the given question is INCOMPLETE.
Xander needs to collect at least 120 cans for a food drive to earn community service credit. He has already collected 64 items. Choose the inequality and solution to represent the number of cans, c, that Xander must still collect.
Now, here:
The number of cans Xander needed to collect = At least 120
The number of items already collected = 64
c: the number of cans, c, that Xander must still collect.
Now, the number of cans to be collected - Cans already collected
= 120 - 64 = 56
So, the number of can he must collect to make a TOTAL OF AT LEAST 120 cans = 56 cans
⇒ The number of cans to be collected ≥ 56 cans
⇒c ≥ 56 cans
or, c ≥ 56 is the REQUIRED INEQUALITY.
Answer:
c ≥ 56 is the REQUIRED INEQUALITY.

Daniella is drawing plans for a garden, measured in feet, which is shown below on the coordinate plane. Daniella has two vertices of the garden at points (Negative3, Negative 1) and (4, Negative 1). On a coordinate plane, points (negative 3, negative 1) and (4, negative 1) are plotted. At which points should Daniella have the other two vertices in order to make the area of her garden 35 square feet? (Negative 3, 1) and (4, 1) (Negative 3, 2) and (4, 2) (Negative 3, 3) and (4, 3) (Negative 3, 4) and (4, 4)
Answer:
d
Step-by-step explanation:
We know that the length of the garden is 4 - (-3) = 7 feet, the answer is (Negative 3, 5) and (4, 5).
What are vertices?A vertex is a point in geometry where two or more curves, lines, or edges intersect.
As a result of this definition, vertices are the points where two lines intersect to form an angle, as well as the corners of polygons and polyhedra.
Let's assume that the other two vertices are at points (a, b) and (c, d). The area of the garden can be calculated as follows:
Area = Length × Width
35 = 7 × (b - (-1)) [since the width is the distance between the y-coordinates of the vertices]
Simplifying the above equation, we get:
b - (-1) = 5
b = 4
So, one of the vertices should be at (a, 4) and the other at (c, 4). Since the garden is symmetrical about the x-axis, the y-coordinate of the missing vertices is 1 more than the y-coordinate of the given vertices. Hence, the other two vertices should be at (−3, 5) and (4, 5).
Therefore, the answer is (Negative 3, 5) and (4, 5).

If DC = 10 centimeters, SR = 15 centimeters, and the area of ABCD is 72 square centimeters, then the area of PQRS is square centimeters.
The area of the figure PQRS can be found by applying the rule of areas in proportional shapes. The area of PQRS equals 32 square centimeters after rounding the calculated value.
Explanation:The given problem involves the calculation of area and the application of ratios. It mentions two figures, ABCD and PQRS, along with certain dimensions and the area of the first figure. To find the area of the figure PQRS, we apply a rule of ratios used in geometry that states the areas of two similar figures is equal to the square of the ratio of their corresponding sides.
The corresponding sides here are DC and SR. So the ratio of their areas would be (DC/SR)². Plugging in the values we get = (10 centimeters/15 centimeters)² which simplifies to 0.444 (after rounding).
Then, to find the area of PQRS, we multiply the area of ABCD (which is 72 square centimeters) with the calculated square of the ratio. Therefore, the area of figure PQRS is 72 * 0.444 which equals 31.968 square centimeters (rounded to 32 square centimeters).

Tickets for a cinema cost £a for adults and £c for children. 2 adults and 3 children cost £42.70. 3 adults and 5 children cost £67.30.
How much does it cost for 1 adult and 1 child?
Answer:
c = 6.5, a = 11.6
Step-by-step explanation:
2a + 3c = 42.7
3a + 5c = 67.3
Elimination
(2a+3c = 42.7)*3
(3a+5c = 67.3)*2
(1) 6a+9c = 128.1
(2) 6a+10c = 134.6
(2) - (1)
c = 6.5
Substitue 'c' in any of the equation
2a + 3(6.5) = 42.7 or 3a + 5(6.5) = 67.3
2a + 19.5 = 42.7 3a + 32.5 = 67.3
2a = 42.7 - 19.5 3a = 67.3 - 32.5
2a = 23.2 3a = 34.8
a = 11.6 a = 11.6
The Tennis Teams of Atlanta need to older tennis balla for the upcoming tournament.They will need 2,367 tennis balls. If each can hold 5 tennis balls,how Many will they purchase
Answer:473
Step-by-step explanation:
Final answer:
To determine how many cans are needed to hold 2,367 tennis balls, with each can holding 5 balls, you divide the total number of tennis balls by 5 and round up to the nearest whole number, resulting in 474 cans.
Explanation:
The subject of the question is Mathematics, as it involves a division problem. The question entails calculating the number of cans needed to hold 2,367 tennis balls, given that each can hold 5 tennis balls. To determine the number of cans required, we divide the total number of tennis balls by the number of balls that can fit in each can.
To find the solution:
Divide 2,367 by 5, which equals 473.4.
Since you can't have a fraction of a can, you would need to round up because you will need part of another can to hold the remaining balls. So, rounding 473.4 up, you get 474 cans.
Therefore, the Tennis Teams of Atlanta need to purchase 474 cans to hold 2,367 tennis balls.

Puppy A weighs 8 pounds which is about 25% of its adult weight what will be the adult weight of a puppy A
Answer:
Step-by-step explanation:
Let x be the adult weight of a puppy A
25% of x = 8 pounds
[tex]\frac{25}{100}*x=8\\\\ x=\frac{8*100}{25}\\\\ =8*4=32pounds\\[/tex]
Final answer:
To calculate the adult weight of Puppy A, divide the current weight of 8 pounds by 0.25 since 8 pounds is 25% of the adult weight. The adult weight of Puppy A is 32 pounds.
Explanation:
The student is asking how to find the adult weight of Puppy A, given that its current weight is 25% of its adult weight. To solve this, we need to use the concept of percentages. If Puppy A currently weighs 8 pounds and this represents 25% of the adult weight, we can set up a proportion:
25% (current weight) / 100% (adult weight) = 8 pounds / adult weight
To find the adult weight, we divide 8 pounds by 25% (0.25 in decimal form):
Adult weight = 8 pounds / 0.25
Adult weight = 32 pounds
Therefore, the adult weight of Puppy A is expected to be 32 pounds.

2
5
of the remaining boats are blue, and the rest are red. If there are 12 red boats, how many boats are in the marina?
Final answer:
To find the number of boats in the marina, we use the information given about the proportion of white, blue, and red boats. By setting up an equation and solving for the total, we find that there are 222 boats in the marina.
Explanation:
To find the number of boats in the marina, we need to start with the information given. The problem tells us that five-sixths of the boats in the marina are white, and then 25 of the remaining boats are blue. The rest of the boats are red, with a total of 12 red boats.
We can start by finding the fraction of boats that are red. Since five-sixths are white, the remaining fraction of boats that are not white is one-sixth. We know that 25 boats are blue, so if we subtract this from the one-sixth, we are left with the fraction that represents the red boats.
Let's set up an equation to solve for the total number of boats:
1/6 - 25 = 12
Simplifying the equation, we have:
1/6 = 12 + 25
1/6 = 37
Multiplying both sides of the equation by 6, we get:
1 = 37*6
1 = 222
Therefore, there are a total of 222 boats in the marina.

(3, 0) and (-5, 0)
(-3, 0) and (5, 0)
(-3, 0) and (-5, 0)
Answer:
(3, 0) and (5, 0)
Step-by-step explanation:
we have
[tex]y=x^{2}-8x+15[/tex]
we know that
The x-intercepts are the values of x when the value of y is equal to zero
so
For y=0
[tex]x^{2}-8x+15=0[/tex]
The formula to solve a quadratic equation of the form
[tex]ax^{2} +bx+c=0[/tex]
is equal to
[tex]x=\frac{-b\pm\sqrt{b^{2}-4ac}} {2a}[/tex]
in this problem we have
[tex]x^{2}-8x+15=0[/tex]
so
[tex]a=1\\b=-8\\c=15[/tex]
substitute in the formula
[tex]x=\frac{-(-8)\pm\sqrt{-8^{2}-4(1)(15)}} {2(1)}[/tex]
[tex]x=\frac{8\pm\sqrt{4}} {2}[/tex]
[tex]x=\frac{8\pm2} {2}[/tex]
[tex]x=\frac{8+2} {2}=5[/tex]
[tex]x=\frac{8-2} {2}=3[/tex]
so
x=3, x=5
therefore
The x-intercepts are (3,0) and (5,0)

Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 2, 0) and (x₂, y₂ ) = (3, 10)
m = [tex]\frac{10-0}{3+2}[/tex] = [tex]\frac{10}{5}[/tex] = 2, thus
y = 2x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (- 2, 0), then
0 = - 4 + c ⇒ c = 0 + 4 = 4
y = 2x + 4 ← equation of line

You and your friend are selling your old CDs. Your friend sells 14 the first day, and x the next day. You sell y the first day and 6 the next day. Write an expression that shows the total number of CDs sold both days. Rewrite your answer using the Commutative Property of Addition.
Answer: 30+x+y
Step-by-step explanation:
Commutative Property of Addition : a+b= b+a , where a and b are any arbitrary numbers.Given : Number of CDs sold by friend on first day = 14
Number of CDs sold by friend on next day = x
Total CDs sold by friend = 14 +x
Number of CDs sold by you on first day = 16
Number of CDs sold by you on next day = y
Total CDs sold by you = 16+y
The expression that shows the total number of CDs sold both days =
Total CDs sold by friend + Total CDs sold by you
= 14 +x+ 16+y
= 14 +(x+ 16)+y
= 14 +(16+x)+y [By Commutative Property of Addition.]
= 14+16+x+y
= 30+x+y
Hence, the expression that shows the total number of CDs sold both days :
30+x+y
