Miguel mixes plant food with water to feed his plants. The instructions on the
plant food say to mix 1 teaspoon of plant food into every 4 cups of water.
b. How much plant food should Miguel add to 7 cups of water? Use a model to show your work
Answers
The plant food should Miguel add to 7 cups of water is 336 plant food
What is Algebra?
One of the many different mathematical disciplines is algebra. Algebra, a common thread that runs through nearly all of mathematics, is the study of mathematical symbols and the rules for using them in formulas.
To feed his plants, Miguel combines water and plant food. According to the directions on the plant food, you should add 1 teaspoon to every 4 cups of water. To demonstrate the relationship between cups of water (w) and teaspoons of plant food (f), create an equation.
48 teaspoons = 1 cup.
1 teaspoon = plants food
4 cups = water.
= 48 teaspoons x 4.
= 192 teaspoons
The formula is:
water in cups = w
Teaspoon of nourishment for plants equals f
The mixture = 192w + f
The relation between f and w is f = kw.
1 teaspoon = plant food
7 cups = water.
= 48teaspoon x 7
= 336teaspoon
The formula is:
water in cups = w
Teaspoon of nourishment for plants equals f
The mixture = 336w + f
Hence, 336 plant food should Miguel add to 7 cups of work

Last week, a share stock gained a total of 1.64 points. Express this gain as a mixed number in simplest form.

Answer: [tex]1\frac{16}{25}[/tex]
Step-by-step explanation:
1.64 is 1 64/100. Now to get the simplest form find a number you can divide both the numerator and the denominator by, like 4. Now you have 1 16/25. 16 and 25 do not have a common number you can divide both by so it is the simplest form.

Hank has just purchased a small rectangular fish tank that holds 950.4 milliliters of water. The tank has a width of 8.8 cm and a height of 9 cm. what is the length of the fish tank?
Answers
We will investigate how to determine one of the indicator dimensions of a regular figure.
We have a rectangular fish tank which can be modeled as a cuboid. The indicator lengths of a cuboid or a rectangular fish tank are as such:
[tex]\begin{gathered} \text{Length ( L ) } \\ \text{Width ( w ) = 8.8 cm} \\ \text{Height ( h ) = 9 cm} \end{gathered}[/tex]One of the indicator lengths of the rectangular fish tank Length ( L ) is unknown. Howver, we are given the total amount of water that the fish tank can withold as follows:
[tex]\text{Water in fish tank = 950.4 mL}[/tex]We will use the conversion factor between milliLiters and centimeter cube as follows:
[tex]1\text{ mL }\to1cm^3[/tex]Therefore,
[tex]950.4\text{ mL }\to950.4cm^3[/tex]The amount of water a fish tank can hold is equivalent to the volume of the fish tank. We have modeled our rectangular fish tank as a cuboid. The volume ( V ) of a cuboid can be expressed in terms of its indicator dimensions as follows:
[tex]V\text{ = L}\cdot w\cdot h[/tex]We can use the above volume expression to determine one off our missing indicator dimension of length ( L ). We plug in the respective quantities and evaluate:
[tex]\begin{gathered} 950.4\text{ = L}\cdot(8.8\text{ ) }\cdot\text{ ( 9 )} \\ \\ L\text{ = }\frac{950.4}{8.8\cdot9}\text{ = }\frac{950.4}{79.2} \\ \\ L\text{ = 12 cm} \end{gathered}[/tex]Therefore, the length ( L ) of the fish tank must be:
[tex]12\text{ cm }\ldots\text{ Answer}[/tex]The sphere at the right fits snugly inside a cube with 4-in. edges. What is the approximate volume of the space between the sphere and cube?
Answers
As given by the question
There are given that the inside edge is 4 in.
Now,
Since sphere fits snugly inside a cube therefore diameter of sphere will be equal to side of the cube
So,
[tex]\begin{gathered} \text{diameter}=4\text{ inches} \\ \text{radius}=\frac{dameter}{2} \\ \text{radius}=\frac{4}{2} \\ \text{radius}=2 \end{gathered}[/tex]Then,
Volume of the sphere is given by:
[tex]\begin{gathered} \frac{4}{3}\times\pi\times r^3=\frac{4}{3}\times3.14\times2^3 \\ =\frac{4}{3}\times3.14\times8 \\ =33.5 \end{gathered}[/tex]And,
The volume of a cube is:
[tex]\begin{gathered} \text{Volume of cube=side}\times side\times side \\ =4\times4\times4 \\ =64\text{ inches} \end{gathered}[/tex]Then,
The volume of the space between the sphere and cube = 64-33.5 = 30.5.
Hence, the answer is 30.5 cube inches.
Fill in the boxes with numbers and operations to reflect the equation of the circle after the transformations
Answers
Given the equation of the circle:
[tex]x^2+4x+y^2-12y=-24[/tex]We will complete the squares for x and y to write the equation of the circle as:
[tex](x-h)^2+(y-k)^2=r^2[/tex]Where (h,k) is the coordinates of the circle and r is the radius of the circle
so, the equation will be:
[tex]\begin{gathered} (x^2+4x+4)+(y^2-12y+36)=-24+4+36 \\ \\ (x+2)^2+(y-6)^2=16 \\ \\ (x+2)^2+(y-6)^2=4^2 \end{gathered}[/tex]So, the radius of the circle = 4
And the center of the circle = ( -2, 6 )
Now, we will make the transformation for the circle:
Shift 1 unit up, the center will be = ( -2, 7 )
shift 2 units right, the center will be = ( 0, 7 )
Reflection across the x-axis, the center will be = ( 0, -7)
So, the equation of the circle after transformation will be:
[tex](x-0)^2+(y+7)^2=4^2[/tex]So, the answer will be:
[tex](x-0)^2+(y+7)^2=16[/tex]The question is in the photo. Complete the fourth one.

Answers
Answer
Explanation
To know how many solutions this system of linear equations have, we willl need to solve it.
2x + 3y = 6
-8x - 12y = -20
Making x the subject of formula in the first equation
2x + 3y = 6
2x = -3y + 6
Divide through by 2
(2x/2) = (-3y/2) + (6/2)
x = (-3y/2) + 3
Substituting this for x in the second equation
-8x - 12y = -20
x = (-3y/2) + 3
