Answer:
Ava's altitude is 3 meters.
Step-by-step explanation:
The position of Ava and Mary can be described by the sides of a right angled triangle. Let Ava's altitude be represented by x.
So that applying the Pythagoras theorem, we have;
[tex]/hyp/^{2}[/tex] = [tex]/Adj 1/^{2}[/tex] + [tex]/Adj 2/^{2}[/tex]
[tex]5^{2}[/tex] = [tex]4^{2}[/tex] + [tex]x^{2}[/tex]
25 = 16 + [tex]x^{2}[/tex]
[tex]x^{2}[/tex] = 25 - 16
= 9
x = [tex]\sqrt{9}[/tex]
= 3
x = 3 meters
Thus, Ava's altitude is 3 meters.

Chloe is planning an event and purchasing floral arrangements. At Petals Plus, the arrangements cost $35.17 each, and the store
charges $67.00 for delivery of the flowers to the event site. At Blooms, the arrangements cost $25.03 each, and the store charges
$108.00 for delivery of the flowers to the event site.
How many arrangements should she purchase from Blooms in order to get a better value?
OA. 3
OB. 5
OC. 1
OD. 4
Answer: You would need at least 5 arrangements to make Blooms a better deal
Step-by-step explanation:
Petals Plus
y= 35.17x+67
Blooms
y= 25.03x+108
35.17x+67 =25.03x+108
10.14x= 41
x= 4.05
1. Which function does not have the set of all real numbers as its domain? A) f(x) = 3x + 7 B) f(x) = x3 - 2x2 + x – 5 C) fx= 2x-3 D) fx= x-7x+4
Answer:
None of the given functions
Step-by-step explanation:
Given
[tex]A)\ f(x) = 3x + 7[/tex]
[tex]B)\ f(x) = x^3 - 2x^2 +x - 5[/tex]
[tex]C)\ f(x)=2x - 3[/tex]
[tex]D)\ f(x)=x^2 - 7x + 4[/tex]
Required
Which do not have set of real numbers as its domain
If a function has no root and no denominator, then the domain of such function is a set of all real numbers
The given functions (a) to (d) do not have square roots and do not have denominators.
Hence, all functions have the set of real numbers as their domain

Answer and Step-by-step explanation:
10 and 20 are the initial amounts, so they don't get a variable. The 3 dollars and 2 dollars every mile gets the variable since the occur every mile.
The equations are:
Blank 1: 3x + 10
Blank 2: 2x + 20
To find when they are equal, we equal the equations together.
3x + 10 = 2x + 20
x = 10
Plug 10 into either equation and solve.
Blank 3: 10 (At 10 miles, the equations are equal)
Blank 4: $40 (The will equal $40)

Convert 7x - y = -9 to slope-intercept form. Simplify your answer.
The equation of a line, 7x - y = -9, converted to slope-intercept form is: y = 7x + 9
Equation of a line in Slope-intercept FormIf "m" is the slope of a line and "b" is the y-intercept, the equation of the line in slope-intercept form is given as: y = mx + b.
Thus, given the equation, 7x - y = -9, rewrite/convert to slope-intercept form as follows:
7x - y = -9
-y = -7x - 9
Divide both sides by -1y = 7x + 9
Therefore, the equation of a line, 7x - y = -9, converted to slope-intercept form is: y = 7x + 9

Russel randomly surveys seventh graders in his school and finds that 6 of 30 attend summer camp. if there are 200 seventh graders in his school, about how many are expected to attend summer camp.
40 seventh-graders are expected to attend summer camp.
Because
6/30=x/200
6/30= 6 divided by 30= 0.2
0.2x200=40
The ratio is 2:5 red beads to blue beads. If you have a TOTAL of 21 beads, how many are red, and how many are blue beads?
Answer:
Number of red beads = 6
Number of blue beads = 15
Step-by-step explanation:
Number of total beads = 21
Ratio of red beads to the blue beads = 2 : 5
Therefore, number of red beads I have = [tex]\frac{2}{2+5}(\text{Total number of beads})[/tex]
= [tex]\frac{2}{7}\times 21[/tex]
= 6 beads
Number of blue beads = [tex]\frac{5}{2+5}\times (21)[/tex]
= [tex]\frac{5}{7}\times 21[/tex]
= 15 beads
Therefore, number of red beads = 6
And number of blue beads = 15

Write the equation of the line that passes through the points (7, –9)
and (1,-4). Put your answer in fully reduced point-slope form,
unless it is a vertical or horizontal line.
Answer:
y=[tex]\frac{-5}{6}[/tex]x+14[tex]\frac{5}{6}[/tex]
Step-by-step explanation:
The equation of a line is y=mx+b
to find the equation of the line you need its gradient(m) and its y intercept(b)
the gradient is
[tex]\frac{y1-y2}{x1-x2}[/tex]
y1= the y value of the first point which is -9
y2=the y value of the second point which is -4
x1=the x value of the first point which is 7
x2=the x value of the first point which is 1
then input the values into the equation
[tex]\frac{(-9)-(-4)}{(7)-(1)}[/tex]
=[tex]\frac{-9+4}{6}[/tex]
=[tex]\frac{-5}{6}[/tex]
to find the y just times the x by the gradient and then minus it from the y
-9-(7 x [tex]\frac{-5}{6}[/tex])=14[tex]\frac{5}{6}[/tex]
making the equation y=[tex]\frac{-5}{6}[/tex]x+14[tex]\frac{5}{6}[/tex]

1. FIND THE AREA OF THE FIGURE.
plzz help meee.!.!.!
Answer:
The answer isn't there
Step-by-step explanation:
We can divide the figure into a rectangle and triangle and add the areas. The area of the rectangle would be length times width: 14 × 12 = 168. The area of a right angled triangle is [tex]\frac{ab}{2}[/tex], where a and b are both legs. a=12 and b=8, so the area would be [tex]\frac{12*8}{2}[/tex] which equals [tex]\frac{96}{2}[/tex], which is 48. Then we add both the areas, 168 + 48 = 216
Mariela recolecto 625 mililitros de agua que gotea de su caño en 10 minutos, ella desea saber ¿cuanta agua gastara en una semana ?
Answer:
En una semana gastará 705,6 litros.
Step-by-step explanation:
Con la información proporcionada, puedes calcular cuánta agua gastará por día usando una regla de tres teniendo en cuenta que un día tiene 24 horas y estas equivalen a 1440 minutos. Además, puedes convertir los 700 ml a litros, considerando que 1 litro son 1000 mL, lo que significa que los 700 mL equivalen a 700/1000=0,7 Litros.
10 min → 0,7 L
1440 min → x
x=(1440*0,7)/10
x=100,8 L
Ahora que conoces la cantidad de agua que gastará por día, puedes multiplicar esta cantidad por 7 que es el número de días en una semana:
100,8*7=705,6 L
De acuerdo a esto, la respuesta es que en una semana gastará 705,6 litros.
Is it possible to use dynamic geometry software to draw a triangle with
angles of 50°, 65°, and 70°? Explain.
Answer:
no
Step-by-step explanation:
The sum of the angles of a triangle must be equal to 180
50+65+70
185
This is not equal to 180 so it does not make a triangle
