Given right triangle ABC with altitude BD drawn to hypotenuse AC. If AB = 3 and AC = 9, what is the length of AD? (Note: the figure is not drawn to scale.)
Answers
Answer:
The length of AD is 1 unit
Step-by-step explanation:
Let us solve the question
In Δ ABC
∵ ∠B is a right angle
∵ BD is perpendicular to the hypotenuse AC
∴ (AB)² = AD × AC ⇒ rule
∵ AB = 3 units
∵ AC = 9 units
∵ AD = x
→ Substitute them in the rule above
∴ (3)² = x × 9
∴ 9 = 9x
→ Divide both sides by 9
∵ [tex]\frac{9}{9}[/tex] = [tex]\frac{9x}{9}[/tex]
∴ 1 = x
∴ The length of AD is 1 unit

Roman created the following table to represent the balance of his loan, y, over a period of months, x. The equation for the line of best fit of Roman's table of dadt is y= -200.22x + 5,014.20.
Answers
Answer: extrapolation, and 25 months
Step-by-step explanation:
I took the Plato test and got it right, but if you want to know. Interpolation means based on the numbers given you could see the answer, extrapolation means you have to go farther than the last plot point given to get your answer. Which you do since it does not go past 12 months.
The second answer you can roughly get by pluging in each of the choices in the equation for x
For example: y=-200.22(25)+5015.20
That should give you an answer pretty close to zero so there is your answer

Un camion lleva 200 cajas. Cada caja contiene 20 paquetes de cafe de un cuarto de kilo. ?Cuantos kilos de cafe lleva el camion?
Answers
Answer:
1000 cajas
Step-by-step explanation:
De la pregunta anterior, sabemos que:
Un camión lleva 200 cajas.
Cada caja contiene 20 paquetes de café de un cuarto de kilo.
Esto significa
1 caja = 20 paquetes (1/4 kilo) de café
1 caja = paquetes de 5 kilos de café
Ya que tenemos 200 cajas en el camión
1 caja = 5 kilo
200 cajas = x
Cruz multiplicar
x = 200 × 5 kilo
x = 1000 kilos
Por tanto, los kilos de café que puede transportar el camión son 1000 kilos.

Answers
Answer:
x + 3
Step-by-step explanation:
3x+2 is the 2nd term
2x-1 is the commind difference (d)
so you just need to substract it
3x+2
-(+2x-1) -------transpose -2x+1
3x+2
-2x+1
---------
x+3
Answer:
a is equal to x + 3
Step-by-step explanation:
Arithmetic Sequences
The arithmetic sequences are identified because any term n is obtained by adding or subtracting a fixed number to the previous term. That number is called the common difference.
We are given the sequence:
a, 3x+2, b
And the common difference is 2x-1
Subtracting the second and the first terms:
3x + 2 - a
We can find the common difference since it's given:
3x + 2 - a = 2x - 1
Solving for a:
- a = -3x - 2 + 2x - 1
- a = -x - 3
a = x + 3
a is equal to x + 3

You are creating a logo for a local company in the shape of an isosceles triangle. The legs measure 5 inches each. What is the greatest number of whole inches the base can measure?
Answers
Answer:
9 inches
Step-by-step explanation:
Here, we want to know the greatest length of the third side
We apply the triangle inequality theorem here
To get the third side, then the sum of the lengths of the two must be greater than the measure of the third side
let us call the third side x
Then;
5 + 5 > x
10 > x
The highest whole number before 10 is 9: so it is the greatest possible whole number the base of the isosceles triangle can have

Find the y-intercept and x-intercept of the line.
5x-3y=10
Answers
x intercept = 2
the solution is in the pic below
(Sorry if it’s wrong!)
Answer:
strategy: put this equation into slope intercept form y = mx + b
then it is easier to find x and y intercepts
Step-by-step explanation:
5x-3y=10
5x-10=3y
5/3x - 10/3 = y
y = 5/3x - 10/3
when x is zero then y is - 10/3, that's the y intercept
when y is zero then x is 2, that's the x intercept
