Step-by-step explanation: 1 gallon is equal to 4 quarts. If Sally needs to fill and refill a 2 quart pitcher with 6 gallons of water, multiply 6 by 4 to get 24.

The dimensions of the slab are:

Length = 3 meters

Width = 10 meters

To find the dimensions of the rectangular slab, we'll use the given area and the expressions for length and width.

Given:

Area = 30 square meters

Length = w

Width = 2w + 4

We can use the formula for the area of a rectangle to solve for w:

Area = Length × Width

Substituting the given values:

30 = w × (2w + 4)

Expanding the equation:

30 = 2w² + 4w

Rearranging the equation in standard quadratic form:

2w² + 4w - 30 = 0

Now, we can solve this quadratic equation using factoring, completing the square, or the quadratic formula. Let's use the quadratic formula:

w = (-b ± √(b² - 4ac)) / (2a)

In this case, a = 2, b = 4, and c = -30. Substituting these values into the formula:

w = (-4 ± √(4² - 4(2)(-30))) / (2(2))

w = (-4 ± √(16 + 240)) / 4

w = (-4 ± √256) / 4

w = (-4 ± 16) / 4

We have two possible solutions for w:

w = (-4 + 16) / 4 = 12 / 4 = 3

w = (-4 - 16) / 4 = -20 / 4 = -5

Since the width of the slab cannot be negative, we discard the second solution (w = -5).

Therefore, the width of the slab (w) is 3 meters.

Now, we can find the length using the given expression:

Length = w = 3 meters

Therefore, the dimensions of the slab are:

Length = 3 meters

Width = 2w + 4 = 2(3) + 4 = 6 + 4 = 10 meters

Answer:

The answer is A

Step-by-step explanation:

5x + 18 = 7x - 12

Subtract 7x from both sides

5x + 18 - 7x = 7x - 12 - 7x

-2x + 18 = -12

Subtract 18 from both sides

-2x + 18 - 18 = -12 - 18

-2x = -30

Divide both sides by -2

-2x/-2 = -30/-2

x = 15

Option D, The area of the rectangle is 6/24 square inches.

The area of a rectangle is calculated by multiplying its length and width. Given a rectangle with a length of 3/8 inch and a width of 2/3 inch, we can find the area using the formula:

Area = Length × Width

Substitute the given values:

Area = (3/8) × (2/3)

To multiply these fractions, multiply their numerators and their denominators:

Area = (3 × 2) / (8 × 3) = 6 / 24

After simplifying the fraction 6/24, we get 1/4.

Therefore, the area of the rectangle is 1/4 square inches. Among the answer choices, Option D (6/24) is equivalent to 1/4, so the correct answer is Option D.

Step-by-step explanation:

By solving the system of equations derived from the problem, we get that the club bought 23 black pens.

Let's denote the number of black pens as 'b' and the number of red pens as 'r'. According to the problem, we have two equations: b + r = 75 (there were 75 pens in total) and [tex]1.75b + 2r = 137[/tex] (the total cost of the pens was $137).

Now, we can solve this system of equations. From the first equation, we can express 'r' as r = 75 - b. Substitute this into the second equation: [tex]1.75b + 2(75-b) = 137.[/tex], simplifying this gives b = 23. So, the club bought 23 black pens.

Answer:

A: [tex]7x+y=801[/tex]

B: [tex]18x+3y=1949[/tex]

Step-by-step explanation:

we are given system of equations as

[tex]84x+12y=9612[/tex]

[tex]126x+21y=13643[/tex]

We can simplify each system of equations

[tex]84x+12y=9612[/tex]

we can factor out common terms

[tex]12\times 7x+12\times y=12\times 801[/tex]

[tex]12(7x+y)=12\times 801[/tex]

we can divide both sides by 12

[tex]7x+y=801[/tex]

now, we can simplify second system of equation

[tex]126x+21y=13643[/tex]

Firstly, we can factor

[tex]7\times 18x+7\times 3y=7\times1949[/tex]

[tex]7(18x+3y)=7\times1949[/tex]

we can divide both sides by 7

4 Bird Feeders

Step-by-step explanation:

3 1/4 ALSO is 13/4

13/4 dived by 3/4 or 13/3 witch is 4 and some extra so it can only fill four feeders fully

Answer:

52 bird feeders

Step-by-step explanation:

First, you must determine how much birdseed the volunteer has in cups. To do this, multiply the 12 pounds by the 3 1/4 cups, as there are 3 1/4 cups in one pound. This means the volunteer has 39 cups of birdseed.

Then you must divide the amount of birdseed the volunteer has (39 cups) by the amount of birdseed needed to fill a bird feeder (3/4 cups), which will give you the amount of  bird feeders the volunteer can fill (52 bird feeders).

[tex]x=7.5[/tex]

Step-by-step explanation:

If you look at the large triangle, you will see that the side [tex]x[/tex] is opposite of 30° angle and the side 15 is opposite of 90° angle (side opposite of 90° angle is called the hypotenuse).

We have the angle, we have the side opposite and the hypotenuse. Which trigonometric ratio relates opposite side and hypotenuse? SINE!

So we use the sin ratio and cross multiply and solve for [tex]x[/tex]:

[tex]Sin(A)=\frac{Opposite}{Hypotenuse}\\Sin(30)=\frac{x}{15}\\x=15*Sin(30)\\x=15*(0.5)\\x=7.5[/tex]

Hence, [tex]x=7.5[/tex]

Answer:

a=3.75 un., b=11.25 un.

[tex]x=7.5\ un.[/tex]

[tex]y=\dfrac{15\sqrt{3}}{4}\ un.[/tex]

[tex]z=\dfrac{15\sqrt{3}}{2}\ un.[/tex]

Step-by-step explanation:

Given triangle is special 30°-60°-90° right triangle. The leg that is opposite to the angle of measure 30° is always equal to half of the hypotenuse. The hypotenuse is of length 15 units, the leg that is opposite to the 30° angle is leg with length of x units, then

[tex]x=\dfrac{15}{2}=7.5\ un.[/tex]

In right triangle with hypotenuse x and legs y and a, angle opposite to the leg a is 30°, then

[tex]a=\dfrac{x}{2}=\dfrac{7.5}{2}=3.75\ un.[/tex]

and

[tex]b=15-a=15-3.75=11.25\ un.[/tex]

By the Pythagorean theorem,

[tex]x^2=y^2+a^2,\\ \\7.5^2=3.75^2+y^2,\\ \\y^2=\left(\dfrac{15}{2}\right)^2-\left(\dfrac{15}{4}\right)^2=\dfrac{225}{4}-\dfrac{225}{16}=\dfrac{675}{16},\\ \\y=\dfrac{15\sqrt{3}}{4}\ un.[/tex]

In right triangle with legs y and b and hypotenuse z, leg y is opposite to 30° angle, then

[tex]z=2y=\dfrac{15\sqrt{3}}{2}\ un.[/tex]

Answer:

The answer is 9 square feet.

The area of the square tabletop is calculated using the formula A=s². Given that the length of one side is 3 feet, we substitute this into the formula to get A = 3², which equals to 9 square feet.

Janice is trying to calculate the area of a square tabletop using the formula A=s², where A represents the area and s stands for the length of one side. Since the length of one side of the square (s) is given as 3 feet, we can substitute this value into the formula, resulting in A = 3².

Squaring 3 (i.e., multiplying 3 by itself) gives us 9, so the calculated area of the square tabletop is 9 square feet.

The circumcenter of the triangle ABC with vertices A(-2,4), B(-2,-2), C(4,-2) is found by locating the intersection of the perpendicular bisectors of the sides. It is calculated to be the point (1,1).

The circumcenter of a triangle is the point where the perpendicular bisectors of the sides intersect. It is equidistant from all three vertices of the triangle. To find the circumcenter of triangle ABC with vertices A(-2,4), B(-2,-2), and C(4,-2), we first find the midpoints of the sides and then the equations of the perpendicular bisectors.

The midpoint of AB is (-2, 1) and the midpoint of BC is (1, -2). The slope of AB is undefined and that of BC is 0. Hence, the slopes of the perpendicular bisectors are 0 and undefined respectively. The equation of the line passing through (-2,1) with slope 0 is y = 1. The equation of the line passing through (1,-2) with undefined slope is x = 1. The intersection of these two lines (circumcenter) is (1,1).

Answer:

2 pens

Step-by-step explanation:

Let x represent the number of pens Linda buys.  Since they cost $2.65 each, this gives us the expression 2.65x.

Adding the cost of the card to this gives us the expression 2.65x+1.17.

She has a total of $9.00; this gives us the equation

2.65x+1.17 = 9.00

Subtract 1.17 from each side:

2.65x+1.17-1.17 = 9.00-1.17

2.65x = 7.83

Divide both sides by 2.65:

2.65x/2.65 = 7.83/2.65

x = 2.95

We cannot buy a portion of a pen, so the most she can buy is 2 pens.

Answer:

The answer is 2 pens.

Step-by-step explanation:

Total amount Linda has in her wallet = $9

Amount spent on buying a card = $1.17

So, amount left with Linda = [tex]9-1.17=7.83[/tex]

Now, she wants to buy pens that cost $2.65, so the maximum number of pens she can buy are = [tex]\frac{7.83}{2.65}= 2.9[/tex]

But, pens cannot be in decimal, so the maximum pens she can buy are 2.
