Answer:
-36
Step-by-step explanation:
We were given the expression as
(c3+d2)
Where our
c=-4
Then d= 10
Then substitute for the values of "c and d" in given expresion, we have
(c3+d2)
(-4)^3 + (10)^2
=-64 + 100
= -36

The boiling temperature (in degrees Celsius) of platinum is 199 more than four times the boiling temperature $z$ (in degrees Celsius) of zinc.
a. Write an expression that represents the boiling temperature (in degrees Celsius) of platinum.
b. The boiling temperature of zinc is 907 degrees Celsius. What is the boiling temperature of platinum?
Answer: THIS IS SO HARD!
Step-by-step explanation:
The required boiling temperature of platinum is 3,739 degrees Celsius.
What is simplification?Simplification involves applying rules of arithmetic and algebra to remove unnecessary terms, factors, or operations from an expression. The goal is to obtain an expression that is easier to work with, manipulate, or solve.
Here,
a. Let's start by defining a variable for the boiling temperature of zinc, which we'll call z.
According to the problem statement, the boiling temperature of platinum is 199 more than four times the boiling temperature of zinc. In other words,
Boiling temperature of platinum = 4z + 199
So the expression that represents the boiling temperature of platinum in degrees Celsius is:
4z+199
b. The problem tells us that the boiling temperature of zinc is 907 degrees Celsius. So we can substitute this value for z in our expression:
4z+199 = 4(907)+199 = 3,739
Therefore, the boiling temperature of platinum is 3,739 degrees Celsius.

Given:
The graph of a parabola.
To find:
The domain, range and check whether it is a function or not.
Solution:
Domain: The set of x-values or input values is known as domain.
Range: The set of y-values or output values is known as range.
A relation is a function if their exist unique outputs for each input. In other words a graph is a relation if it pass the vertical line test.
Vertical line test: Each vertical line intersect the graph at most once.
The given function is defined for all real values of x which are greater than or equal to -3. So, the domain of the given graph is:
[tex]Domain=[-3,\infty)[/tex]
The given function values can be any real number. So, the range of the given graph is:
[tex]Range=(-\infty,\infty)[/tex]
For x=0, we have two values of the function because the graph intercept the y-axis at two points.
Since the graph does not pass the vertical line test therefore the given graph is not a function.

EMERGENCY PLS HELP: Calculate the volume.
Answer:
[tex]525\pi[/tex]
Step-by-step explanation:
Volume of a cylinder is given by the function [tex]v=\pi r^{2}h[/tex]
where v is volume, r is radius and h is height.
In order to find the radius we just divide the diameter in half and get
[tex]\frac{10}{2} =5=r[/tex]
now we just plug the values in the formula
[tex]v=\pi r^{2}h\\=\pi (5^{2})(21)\\=\pi (25)(21)\\=525\pi[/tex]
Answer:
Volume of a cylinder: V = π (r^2) h
Step-by-step explanation:
First, find your radius and your height.
H = 21
D = 10
R = 1/2 d = 5
Then plug them into the equation: V = π (r^2) h
V = π (5^2) 21
V = π (25) 21
V = π (25 x 21)
V = π (525)
V = 525π

Given:
Post office is located at P(1,5).
Market is located at Q(4,9).
To find:
Distance between the post office and the market.
Solution:
Distance between two points is:
[tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
The post office is located at P(1,5) and the market is located at Q(4,9). So, the distance between the post office and the market is:
[tex]PQ=\sqrt{(4-1)^2+(9-5)^2}[/tex]
[tex]PQ=\sqrt{(3)^2+(4)^2}[/tex]
[tex]PQ=\sqrt{9+16}[/tex]
[tex]PQ=\sqrt{25}[/tex]
[tex]PQ=5[/tex]
The axes show distance in miles.
Therefore, the distance between the post office and the market is 5 miles.
Guido tiene la cuarta parte de la edad de su padre Andrés y el triple de la edad de su hermano David. ¿Qué edad tiene cada uno, si sus edades suman 48 años?
Answer:
Guido tiene 9 años, Andrés tiene 36 años y David tiene 3 años.
Step-by-step explanation:
Con la información proporcionada, sabes que la edad de los tres suma 48, lo que se puede expresar como:
x+y+z=48, donde:
x es la edad de Guido
y es la edad de Andrés
z es la edad de David
Además, de acuerdo al enunciado puedes decir que la edad del papá Andrés es cuatro veces la edad de Guido y que la edad de David es la tercera parte de la edad de Guido y puedes escribir las siguientes ecuaciones:
y=4x
z=x/3
Ahora puedes reemplazar estas dos ecuaciones en la primera y despejar x:
x+4x+x/3=48
5x+x/3=48
16x/3=48
16x=48*3
16x=144
x=144/16
x=9
Después, puedes reemplazar el valor de x en y=4x para encontrar el valor de y:
y=4x
y=4*(9)
y=36
Finalmente, debes reemplazar el valor de x en z=x/3 para encontrar el valor de z:
z=x/3
z=9/3
z=3
De acuerdo a esto, Guido tiene 9 años, Andrés tiene 36 años y David tiene 3 años.

If you double all of the dimensions of a rectangular prism, you create a similar prism with a scale factor of 2. The surface area of the similar prism will increase as the square of the scale factor (22 = 4) and the volume will increase as the cube of the scale factor (23 = 8).
Find the volume of a pyramid with a square base, where the area of the base is 16\text{ m}^216 m
2
and the height of the pyramid is 25.4\text{ m}25.4 m. Round your answer to the nearest tenth of a cubic meter.
The volume of the pyramid with a square base is 135.5 cubic m if the base area is 16 cubic m and the height is 25.4 m.
What is a square pyramid?In geometry, it is defined as the shape having a square base with equal sides length and all the vertex of the square's joints at the top, which is perpendicular to the centre of the square.
We know the volume of the square pyramid V;
V = Bh/2
B is the base area, B = 16 square m
h is the height of the pyramid, h = 25.4 m
V = (16×25.4)/3
V = 135.46 ≈ 135.5 cubic m
Thus, the volume of the pyramid with a square base is 135.5 cubic m if the base area is 16 cubic m and the height is 25.4 m.

You have been asked to analyze the popcorn recipes of three different local theatres in order to figure out which theatre has the best popcorn. In this case, the "best" popcorn is the most buttery! In your quest to find the best, you meet with each theatre manager individually and ask for the ratio of oil to popcorn kernels that they use in their recipes. Here are their responses.
The manager of Theatre A says that they usually go through about 15 cups of popcorn kernels and about 5 cups of oil each weeknight.
The manager of Theatre B says that they order 18 cups of oil and 72 cups of popcorn kernels each week.
The manager of Theatre C says that their concessions use 6 cups of oil and 32 cups of popcorn kernels on a busy Saturday.
You also ask about the amount of salt each theatre uses in their recipe. Their responses are below.
Theatre A uses 2 cups of salt for every 10 cups of oil.
Theatre B uses cup salt for every cup of oil.
Theatre C uses 1 cup of salt for every 6 cups of oil.
Remember that ratio relationships can be described with equations. Let O represent oil, P represent popcorn kernels, and S represent salt. Which statement is true about the value of the oil to salt ratio for Theater B?
For Theatre B, the ratio of oil to salt can be described by the equation O = 8 × S.
For Theatre B, the ratio of oil to salt can be described by the equation O =1/8×S.
For Theatre B, the ratio of oil to salt can be described by the equation S = 8 × O.

On the drawing for a house plan, the master bedroom is rectangular and has dimensions of 2.25 inches by 2.5 inches. If the scale of the drawing is inch = 1 foot, what is the actual area of the master bedroom? Make sure to label your answer.
Answer:
0.03906square foot
Step-by-step explanation:
Given the dimension of the bedroom yo be 2.25in by 2.5in
First we need to convert to foot
2.25in = 0.08333×2.25 = 0.1875feet
2.5in = 0.08333×2.5 = 0.2083feet
Area of the rectangular bedroom = length × width
Area of the rectangular bedroom = 0.1875×0.2083
Area of the rectangular bedroom = 0.03906square foot
