Juan, Pedro, Luis y José salieron hacia el club. Algunos se pararon a descansar en el camino. Juan iba en bicicleta. Pedro en moto. Luis corriendo y José caminando. Juan recorrió 5/6 del camino, Pedro 2/3, Luis 1/2 y José 11/12 del camino. ¿Quién está más cerca del club?
Answer:
is closer to the club José
is looking for a common denominator
Juan 5/6 = 10/12
Pedro 2/3 = 8/12
Luis 1/2 = 6/12
José 11/12
the largest is chosen
Solve for x: 3(x + 1) = −2(x − 1) − 4
Answer:
x = -1
Step-by-step explanation:
the 6th term of a gp is -2/29,and it's first term is 18.what is the common ratio
Answer:
-0.329
Step-by-step explanation:
The formula for Geometric ratio is
an = ar^n - 1
Where
a = First term = 18
r = Common ratio = ?
n = Number of term= 6
Hence
a6 = 18 × r^6-1
From the question
a6 = -2/29
Hence:
-2/29 = 18 × r^6-1
-2/29 = 18 × r⁵
Divide both sides by 18
-2/29 ÷ 18 = 18 × r⁵/18
-2/29 × 1/18 = r⁵
r⁵ = -1/261
Take the fifth root of both sides
⁵√(r⁵) = ⁵√(-1/261)
r = -0.3286032834
Approximately = -0.329
Therefore, Common ratio = -0.329

Is triangle ABC: A(2, -1), B(5, -1) C(5, 3), a right triangle? Explain in at least 5-7 sentences at a minimum.
Answer:
yes it is because a right angle triangle has a 90 degree angle and the other sides are equal
pat calculated tan(88)° and obtained a value of 28.6363, but isn't sure what that value means in context. write at least one sentence and provide a sketch to help her understand what her calculator is telling her.
Step-by-step explanation:
tangent is the ratio of opposite (o) to adjacent (a). it means when an angle is getting bigger, it will impact to the ratio of o/a and reaching infinite value at the angle 90°.

Find the equation of the line that is parallel to the line
y = 3x + 3 and passes through the point (10,1). Write the
equation in slope-intercept form.
9514 1404 393
Answer:
y = 3x -29
Step-by-step explanation:
The parallel line will have the same slope: 3. The y-intercept can be found from ...
b = y -mx
b = 1 -(3)(10) = 1 -30 = -29
Then the slope-intercept equation is ...
y = 3x -29

A tube of toothpaste holds 75 ml.
How many tubes can be filled using 3 litres of toothpaste?
Pls help
Answer:
40 tubes
Step-by-step explanation:
1 liter = 1,000 milliliters
2 liters = 2,000 milliliters
3 liters = 3,000 milliliters
A tube of toothpaste = 75 ml
How many tubes can be filled using 3 litres of toothpaste?
Let
x = number of tubes
x tubes of toothpaste = 3000 ml
x = 3000 ml / 75 ml
x = 40
x = number of tubes = 40 tubes

The triangle below is equilateral. Find the length of side x x in simplest radical form with a rational denominator
Answer:
x = √30
Step-by-step explanation:
We are given an equilateral triangle, so the angles will all be (180/3). = 60
Therefore, the angle opposite x is 60° ; hence. We can use trigonometry to obtain the value of x
Tan θ = opposite / Adjacent
Tan 60 = x / √10
Tan 60 = √3
Hence,
√3 = x / √10
x = √3 * √10
x = √30

Angelica reads 15 pages of a book each day. In 10 days, she reads 200 pages. Assume the relationship is linear. Find and interpret the rate of change and initial value
Plz help
Answer:
rate of change: 15 pages per day
initial value: 50 pages
Step-by-step explanation:
In this scenario, the rate of change is 15 pages per day. This means that every single day Angelica can read 15 pages of the book and that is the number by which her total read pages will change. In 10 days Angelica can read 150 pages (10 days * 15 pages per day). Since the question states that in 10 days Angelica has read 200 pages then this means that the initial value of pages read would be 50 since this would be the number of missing pages to obtain the 200 read pages in a span of 10 days...
200 - 150 = 50 pages.

Two angles of a triangle measure fifty degrees and forty degrees. What does the third angle measure?
Need ans ASAP giving u 15points
Answer:
The answer is 90 degrees
Answer:
third angle is 90 degree
Step-by-step explanation:
one angle is 50 degree
another angle is 40 degree
third angle = ?
let third angle be x
50 + 40 + x =180 degree (sum of interior angles of a trianglle)
90 + x =180
x = 180 - 90
x = 90 degree

what is an equation in standard form of an ellipse centered at the origin with vertex (-4,0) and co-vertex (0,5)???
Answer:
[tex]\frac{x^2}{16}+\frac{y^2}{25}=1[/tex]
Step-by-step explanation:
The equation of an ellipse with a center at [tex](h, k)[/tex] and vertices at [tex](h\pm a, k)[/tex] and [tex](h, k\pm b)[/tex] is given by [tex]\frac{(x-h)^2}{a^2}+\frac{(y-k)^2}{b^2}=1[/tex].
Since two vertices are located at (-4, 0) and (0, 5), the other vertices must be located at (4, 0) and (0, -5).
What we know:
Center of (0, 0)From [tex](h\pm a, k)[/tex], [tex]a[/tex] must be 4From [tex](h, k\pm b)[/tex], [tex]b[/tex] must be 5Thus, we have:
[tex]\frac{(x-0)^2}{4^2}+\frac{(y-0)^2}{5^2}=1\implies \boxed{\frac{x^2}{16}+\frac{y^2}{25}=1}[/tex]

[tex]\frac{9^6 \cdot 9^0 \cdot 9^4}{9^7} = 9^{6 + 0 + 4 -7} = 9^{10-7} = 9^3[/tex]
Answer:
9^3
Step-by-step explanation:
When we want to multiply exponents, we use the formula a^m x a^n= a^m+n.
In this case, we can see that 9 is our a, and their respective exponents are mn and n.
9^6 x 9^0 x 9^4 = 9^6+0+4= 9^10
When dividing exponents we subtract the exponents for each number from the top. For example, 9^10/9^7= 9^10-7= 9^3
If we want to simplify this even further, 9^3 = 729.
Hope this helps!

Find the side length of x (trigonometry)
Answer:
x=12.124
Step-by-step explanation:
here 7 and x are the legs of the triangle where as 14 is hypotenuse because it is opposite opposite to 90 degree.
using pythagoras theorem
a^2 + b^2 = c^2
here and b are legs and c is hypotenuse
7^2 + x^2 = 14^2
49 + x^2 = 196
x^2 =196-49
x^2 =147
x=[tex]\sqrt{147}[/tex]
x=12.1243
x=12.124 (after converting to the nearest hundredth)

99 points waiting for the person that answers the question
Answer:
No
Step-by-step explanation:
This is from a website so you might have to rephrase it but Direct variation describes a simple relationship between two variables . We say y varies directly with x (or as x , in some textbooks) if:
y=kx
for some constant k , called the constant of variation or constant of proportionality . (Some textbooks describe direct variation by saying " y varies directly as x ", " y varies proportionally as x ", or " y is directly proportional to x .")
This means that as x increases, y increases and as x decreases, y decreases—and that the ratio between them always stays the same.
The graph of the direct variation equation is a straight line through the origin.
