Answer:
x = 15, ∠ B = 108°
Step-by-step explanation:
∠ A and ∠ B are alternate exterior angles and congruent, so
6x + 18 = x + 93 ( subtract x from both sides )
5x + 18 = 93 ( subtract 18 from both sides )
5x = 75 ( divide both sides by 5 )
x = 15
Then
∠ B = x + 93 = 15 + 103 = 108°
A manager at a coffee shop is mixing his own coffee blend. He is using beans from Zimbabwe (z), which have a 1.10% caffeine content, and beans from Costa Rica c which have a 1.35% caffeine content. If he wants to make an 11-pound blend that has a 1.16% caffeine content, which system of equations would allow him to determine how much of each type of bean to include in the blend?

A. Graph A
B. Graph B
C. Graph C
D. Graph D
Answer:
I would say graph a is the correct answer
Step-by-step explanation:
Based on the given inequality of y≥ x - 1, the graph that matches it best is C. Graph A.
What is inequality?An inequality is a relation which makes a non-equal comparison between two numbers or mathematical expressions.
We know that how are inequalities graphed:
When graphing an inequality with the "greater or equal" and "less or equal" signs, the line will be a steady line as shown by graphs A and B.
If y is the larger or equal variable, the shaded area will be to the left of the line.
The inequality is y≥ x - 1 which means that the line should be steady and the shading should be on the left of the line.
Graph A is therefore the correct graph.

Which equation can be used to solve for x in the parallelogram below?
A) 3x-12=6x+12
B) (7x-8)+(6x+12)=90
C) 3x-12=2x+8
D) (7x-8)+(6x+12)=180
Answer:
B. (3x - 12)° = (2x + 8)°
Step-by-step explanation:
This equation can be used to solve x.
3x - 12 = 2x + 8
3x - 2x = 12 + 8
x = 20°
-------------------------------------------------------------------
Verification:
3(20) - 12 = 2(20) + 8
60 - 12 = 40 + 8
48° = 48°

The height of a cone is dependent on its radius. The height for a cone radius of 1 is 9.
VolumeVolume is the amount of space that is occupied by a three dimensional object.
The volume of a cone (V) is given by:
V = (1/3)πr²h
Where r is the radius and h is the height.
For a radius of 1:
3π = (1/3)π*(1)² * h
h = 9
For a radius of 2:
3π = (1/3)π*(2)² * h
h = 2.25
For a radius of 5:
3π = (1/3)π*(5)² * h
h = 0.36
For a radius of 12:
3π = (1/3)π*(12)² * h
h = 0.02
The height of a cone is dependent on its radius. The height for a cone radius of 1 is 9.

Autumn's family took a road trip to Mount Rushmore. Autumn fell asleep 39% of the way through the trip. If Autumn fell asleep after they had travelled 351 miles, what was the total length of the trip?
Answer:
900 miles long
Step-by-step explanation:
Given data
Le the total mile of the trip be x
Autumn fell asleep at 39% of the trip, which is equal to 351 miles
so
=39/100*x= 351
0.39x= 351
divide both sides by 0.39
x= 351/0.39
x= 900 miles
Hence the trip is 900 miles long
Answer:
900

A hemisphere fits snugly inside a cylinder with a radius of 12 cm. A cone fits snugly inside the same hemisphere. What is the volume of the cylinder in terms of LaTeX: \piπ? Show all work.
Answer:
The volume of the cylinder is 1,728·π cm³
Step-by-step explanation:
The given parameters are;
The radius of the cylinder, r = 12 cm
The location of the hemisphere = Inside the cylinder
The size relationship between the hemisphere and the cone = Snuggly fit
Therefore, we have;
The radius of the hemisphere = The radius of the cylinder = 12 cm
The height of the cylinder, h = The radius of the hemisphere = 12 cm
The volume of the cylinder, V = π·r²·h
Where;
h = 12 cm
r = 12 cm
Therefore;
V = π·r²·h = π × (12 cm)² × 12 cm = (12 cm)³·π = 1,728·π cm³
The volume of the cylinder, V, in terms of pi (π) is, V = 1,728·π cm³.

Determina el número de átomos que tiene una
muestra de 0.7 gramos de uranio puro si la
masa de un átomo de uranio es de 4 x 10^-25 kg
Tomando el cociente entre la masa de la muestra y la masa de un átomo, veremos que hay 1.7*10^21 átomos de uranio en la muestra.
¿Como podemos determinar el número de átomos?Para determinar el número de átomos en la muestra, simplemente debemos dividir la masa de la muestra (0.7 gramos) por la masa de un átomo de uranio (4*10^(-25) kg)
Donde la complicación viene por que tenemos distintas unidades.
Para resolver esto, podemos escribir la masa de la muestra en kilogramos.
Sabemos que: 1g = 1*10^-3 kg
Entonces podemos reescribir la masa de la muestra como:
0.7g = (0.7)*(10^-3 kg) = 7*10^-4 kg
Ahora si podemos tomar el cociente, el número de átomos esta dado por:
[tex]N = \frac{7*10^{-4}kg}{4*10^{-25}kg} = 1.7*10^{21}[/tex]
Así podemos concluir que hay 1.7*10^21 átomos de uranio en la muestra.
