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.

What type of polynomial is this? 6x + 3
Answer:
Binomial
Step-by-step explanation:
A binomial has two terms. Each term consists of a coefficient, and a variable with an exponent. We can see the two terms:
6x (the exponent would be 1) + 3 (the variable and exponent would be x to the 0. Any variable to the power of 0 is equal to 1, which is why it's not shown)

O-1 and 8
О 1 and 4
O 2
O 3
Answer:
X = 2
Step-by-step explanation:
-1/2X+4= X+ 1
Add 1/2X to each side
-1/2X+ 1/2 X+4= X+ 1 + 1/2 X
4 = 3/2 X +1
Subtract 1 from each side
4-1 = 3/2 X +1-1
3 = 3/2 X
Multiply each side by 2/3 to isolate x
3 * 2/3 = 3/2 X * 2/3

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

Hi so i have a question that is..... A pool is in the shape of a right rectangular prism and has a volume of 192 cubic feet. The area of the base of the pool is 32 square feet. Could anyone help me?
Answer:
h = 6 feet
Step-by-step explanation:
Given that,
The volume of a right rectangular prism = 192 cubic feet
The area of the base of the pool is 32 square feet.
We need to find the height of the prism. We know that the volume of a right rectangular prism is given by :
[tex]V=lbh[/tex]
We have, V = 192 cubic feet, lb = 32 sq feet
So,
[tex]h=\dfrac{V}{lb}\\\\h=\dfrac{192}{32}\\\\=6\ feet[/tex]
So, the height of the prism is equal to 6 feet.

Help how do I solve for x and y when they are they on the same corresponding side
Answer:
y = 33.94 mm
x = 19.80 mm
Step-by-step explanation:
Because AC = CB, then ∠ABC = 45°
cos ∠ABC = 24/y
cos 45° = 0.7071 = 24/y
y = 33.94 mm
EF/BC = x/y
14/24 = x/33.94
24x = 475.16
x = 19.80 mm

Answer:
Below in bold.
Step-by-step explanation:
C1 = 180 - C2
= 180 - (170-2x)
= 10 + 2x
So B3 = 10+2x (alternate angles).
and B2 = 90 - B3
= 90 - (10 + 2x)
= 80 - 2x.

→X x K i m 0 2 x XJL is a common tangent to circles M and K at point J. If angle MLK measures
619, what is the length of radius MJ? Round to the nearest hundredth. (Hint:
Show that triangles LMJ and LKJ are right triangles, and then use right triangle
trigonometry to solving for missing sides of the right triangles.) (10 points)
pls help
Answer:
MJ = 6.5
Step-by-step explanation:
Tangent lines to a circle are perpendicular to the radius.
tan 68° = JL/3
2.4751 = JL/3
JL = 7.4253
∠JLK = 90° - 68° = 22°
∠MLJ = 61° - 22° = 39°
sin 61° = MJ/7.4253
MJ = 7.4253(0.8746) = 6.5
The length of radius MJ is 5.99 units
How to calculate the radius MJ?Start by calculating the length JL using the following tangent ratio
tan(68°) = JL/3
Make JL the subject
JL = 3 * tan(68°)
Evaluate the product
JL = 7.4
From the figure, the measure of angle MLJ is:
∠MLJ = MLK - JLK
Where:
∠JLK = 90° - 68° = 22°
So, we have:
∠MLJ = 61 - 22
∠MLJ = 39
The radius MJ is then calculated using the following tangent ratio
tan(39) = MJ/JL
This gives
tan(39) = MJ/7.4
Make MJ the subject
MJ = 7.4 * tan(39)
Evaluate
MJ = 5.99
Hence, the length of radius MJ is 5.99 units
