Answer:
The height of Ara's tree is 50/3 feet while Vartan's tree is 25/3 feet high
Step-by-step explanation:
Represent Ara's tree with A and Vartan's with V
Given
[tex]A = 2V[/tex]
[tex]A + V = 25[/tex]
Required
Determine A and V
[tex]A = 2V[/tex]
[tex]A + V = 25[/tex]
Substitute 2V for A in [tex]A + V = 25[/tex]
[tex]2V + V= 25[/tex]
[tex]3V = 25[/tex]
Divide both sides by 3
[tex]V =\frac{25}{3}\ feet[/tex]
Recall that [tex]A = 2V[/tex]
So:
[tex]A = 2 * \frac{25}{3}\ feet[/tex]
[tex]A = \frac{2 * 25}{3}\ feet[/tex]
[tex]A = \frac{50}{3}\ feet[/tex]
Hence, the height of Ara's tree is 50/3 feet while Vartan's tree is 25/3 feet high
27 piece of steel is cut into three pieces so that the second piece is twice as long as the first piece and the third piece is 1 inch more than five times the length of the first piece. find the length of pieces
Answer:
where x is the length of the first place
[tex]x+1x+5x+1=27[/tex]
[tex]x=\frac{26}{7}[/tex]
Answer:
first piece: 3.25 inches
second piece: 6.5 inches
third piece: 17.25 inches
Step-by-step explanation:
a + b + c = 27
b = 2a
c = 5a + 1
a = first piece length
b = second piece length
c = third piece length
then:
a + 2a + (5a+1) = 27
8a + 1 = 27
8a = 27-1
8a = 26
a = 26/8
a = 3.25 in
b = 2a
b = 2*3.25
b = 6.5 in
c = 5a+1
c = 5*3.25 + 1
c = 16.25 + 1
c = 17.25 in
Check:
3.25 + 6.5 + 17.25 = 27

What is the distance between the points (4, -2) and (-1, 10)?
Answer:
d = 13 (distance between two points)
Step-by-step explanation:
(4, -2) and (-1, 10)
(X1, Y1) and (X2, y2)
distance between two points = d = sqrt (X2 - X1)² + (Y2 - Y1)²
d = √ (-1 - 4)² + (10 - (-2))²
d = √25 + 144
d = √169
d = 13 (distance between two points)

the letters a,b and c, represent nonzero constants. Solve ax+b=c for x
Answer:
[tex]x = \frac{c-b}{a}[/tex]
Step-by-step explanation:
To solve for x, x needs to be on one side while all the other variables are on the other
To do this first subtract b from each side making the equation,
ax = c - b
Now divide by a on both sides. This means that to solve for x the equation must be ...
[tex]x = \frac{c-b}{a}[/tex]
Using the graph provided, find f(−2)
Answer:
f(-2) = 1
Step-by-step explanation:
f(-2) means find the y value when x = -2
Going to x=-2 and going up until we hit the blue line
f(-2) = 1
Answer:
[tex]\Large \boxed{f(-2)=1}[/tex]
Step-by-step explanation:
For f(-2), the input of the function f(x) is -2.
The input is the x value.
[tex]x = -2[/tex]
The output is the value of y.
When x = -2 on the graph, y = 1.
the equation, Y=10x represents a proportional relationship. what is the constant of proportionally?
Answer:
10
Step-by-step explanation:
Proportional relationships are written in the form y = kx where k is the constant of proportionality. In this case, k = 10 so the answer is 10.
If f(x) = -6x - 3, find f(x) = 21.
Answer:
[tex]\huge \boxed{x=-4}[/tex]
Step-by-step explanation:
[tex]\sf f(x)=-6x-3 \\\\\\ f(x)=21[/tex]
Applying substitution method and solving for the value of x.
[tex]\sf 21=-6x-3[/tex]
Adding 3 to both sides.
[tex]\sf 24=-6x[/tex]
Dividing both sides by -6.
[tex]\sf -4=x[/tex]

Now we have to put the value in the given equation
f(x) = -6x-3
f(21) = -6(21) -3
= - 126 -3
= -129

El Sr negron tiene que redactar una serie de cartas en su oficina. A Lourdes le toma 6 horas pasar todas las cartas. A su compañera rosabel, le toma 9 horas en realizar la misma tarea. Si ambas trabajan juntas para hacer todo el trabajo d ela oficina,
a. Cuánto tiempo le tomará a ambas realizar el trabajo?
Answer:
El tiempo que tardarán Lourdes y Rosabel en hacer el trabajo juntas es de 3,6 horas.
Step-by-step explanation:
Los parámetros dados son;
El tiempo que tarda Lourdes en leer las letras = 6 horas
El tiempo que le toma a Rosabel leer las letras = 9 horas
Sea la cantidad total de trabajo de oficina = X
Deje que el tiempo que ambos tienen que trabajar para hacer el trabajo = t
Por lo tanto;
La tasa de trabajo de Lourdes = X / 6
La tasa de trabajo de Rosabel = X / 9
X / 6 × t + X / 9 × t = X
t × (1/6 + 1/9) = 1
t × 5/18 = 1
t = 18/5 = 3,6 horas
Por lo tanto;
El tiempo que les llevará a Lourdes y Rosabel hacer el trabajo juntas = 3.6 horas.

Step-by-step explanation:
Amir wants to do a full painting on the surface of a pottery. The pottery is in the shape of a cylinder with a height of 14 cm and a radius of 4.5 cm. If one tube of colour can be used to paint 120 cm² of drawing, calculate the number of tubes of colour needed to paint 15 potteries of the same type.
Answer:
About 66 tubes
Step-by-step explanation:
Cylinder surface area formula: 2πr(h + r) where h = height and r = radius
In this case, h = 14, π = 3.14 and r = 4.5 so the surface area of one pottery is:
2 * π * 4.5 * (14 + 4.5) = 166.5π ≈ 523.08
The surface area of 15 potteries would be 523.08 * 15 = 7846.2 so it would take 7846.2 / 120 = 65.385 ≈ 66 tubes. We round to the nearest integer because in this context, you can only have integer values of tubes, you can't have, say, 0.5 tubes.

12 people fit comfortably in a 5 x 5 foot square.use this value to estimate of a crowd that is 10 feet deep on both sides of the street along a 1 mil section of a parade route
Answer:
48 people
Step-by-step explanation:
It states that 12 people fit into a 5 x 5 ft² area.
Here, we are given the length and breath of the side, both 5 ft. And from that, we can estimate the area of the place.
Area of a square is gotten by multiplying both sides together, and thus
5 * 5 = 25 ft²
We are told 12 people fit into 25 ft². In order to get the number of people that fit a 10 x 10, we first need to calculate the area.
We already have the length and breadth to be 10 ft each, so
Area = 10 * 10 = 100 ft²
Now, we calculate.
If
12 people fit into 25 ft²
x people will fit into 100 ft²
If we cross multiply, we have
1200 = 25x
We then divide both sides by 25
x = 1200 / 25
x = 48
Therefore, 48 people will fit into a 10 x 10 ft area

Ben's average speed will be equal to 70.5 meters per minute.
What is an average speed?Calculating average speed involves dividing the whole distance travelled by the total time it took to cover that distance. Speed is defined as the ratio of the time distance travelled by the body to the time taken by the body to cover the distance.
It is given that Ben walks 500 meters from his house to the corner store. He then walks back toward his house but continues 200 meters past his house to talk to a neighbour. It takes Ben 17 minutes from the time he leaves his house until he stops to talk to his neighbour.
The average speed is calculated as below:-
Average speed = Total distance / Total time
Average speed = ( 500 + 500 + 200 ) / 17
Average speed = ( 1200 ) / 17
Average speed = 70.5 meters per minute.
Therefore, Ben's average speed will be equal to 70.5 meters per minute.

Phalicia is a senior at North HS and wants to begin saving for college. She's trying to choose between two savings account options.
Option 1: Phalicia deposits $300 and deposits an additional $50 each month.
Option 2: Phalicia deposits $5 and it triples each month.
Which option should she choose
Answer:
Option 2
Step-by-step explanation:
Let's say that Phalicia opens her savings account one year (12 months) before she goes to college.
With Option 1, she would have saved 300 + 50 * 11 = $850. We do 50 * 11 and not 50 * 12 because she deposits $50 for 11 months, not 12.
With Option 2, she would have saved 5 * 3¹¹ = $885735. Note that we do 3¹¹ and not 3¹² because 5 is being tripled 11 times.
Obviously, she should choose Option 2 because she saves A LOT more money.
Additionally, we can notice that Option 1 is an example of an arithmetic sequence whereas Option 2 is an example of a geometric sequence. Their explicit formulas would be aₙ = 50n + 250 and aₙ = 5 * 3⁽ⁿ⁻¹⁾ respectively.

Nadia is mountain climbing. She started at an altitude of 19.26 feet below sea level and then changed her altitude by climbing a total of 5,437.8 feet up from her initial position. What was Nadia's altitude at the end of her climb?
Answer: 5418.54 feet
Step-by-step explanation:
Given: Nadia started at 19.26 feet below sea level.
She climbed a total of 5,437.8 feet up from her initial position.
Since we take negative integers to show depth .
Here, 19.26 feet below sea level. means - 19.26 feet respective to sea level
So her altitude at the end of her climb above sea level = 5437.8-19.26 feet =
= 5418.54 feet
Hence, Nadia's altitude at the end of her climb was 5418.54 feet.
