Answer:
there are two different, real roots.
Step-by-step explanation:
The coefficients of this quadratic are {1, -7, -8}. Let's find the discriminant, b^2 - 4ac. In this case a = 1, b = -7 and c = -8 and so the discriminant value is
(-7)^2 - 4(1)(-8), or 49 + 32, or 81.
Because the discriminant is positive, we know immediately that there are two different, real roots.
We are not asked to find the roots, but let's do it anyway:
-(-7) ± √81
x = ------------------ => x = 8 and x = -2 (which are real and different from
2 one another).
lope harvested 163.5 kilos of pomelos while marcon harvested 362.75 kilos of pomelo from their farm who harvested more pomelos? by how much more
Answer:
Marcon and 199.25 kilos
Step-by-step explanation:
According to the given situation
As we can see that Marcon has more pomelos harvested as he contains 362.75 kilos while lope harvested 163.5 kilos of pomelos
Also the difference between them is
= 362.75 - 163.5
= 199.25 kilos

Step-by-step explanation:
Answer:
251.2 cm square
Step-by-step explanation:
Diameter = 8 cm
Height = 5 cm
8 / 2 = 4
Radius = 4 cm
r^2 * Pi
4 * 4 = 16
16 * Pi = 50.2654824574
16 x 3.14 = 50.24
Base x Height
50.2654824574 x 5 = 251.327412287
50.24 x 5 = 251.2 cm square

could someone please help me with part b ?
Answer:
The answer is c, C=1.5w + 5
Step-by-step explanation:
Let's write a general equation first,
C = mw + b, where C represents the shipping cost, w is the weight, m and b are non-zero constants.
By using the set of data in the table, what we can do is to substitute the corresponding values into our general equation. [Use any 2 set of numbers]
11 = 4w + b --(1)
17 = 8w + b --(2)
Here we got 2 equations, 2 unknown, thus we can get
w = 3/2, b = 5
The answer is c, C=1.5w + 5
[Noted that if you already got the slope(the yellow words), you can simply substitute one set of numbers into C=1.5w + b to find the value of b]

A researcher wants to know if eating a mint affects whether people can distinguish between two popular orange juice brands. To conduct an experiment, the researcher places 50 participants in two groups. The treatment group will eat a mint before drinking a juice, while the control group will not eat a mint before drinking. Then the participants will guess the juice brand. To select the groups, the researcher labels each participant with a number and selects slips of paper labeled 1–50 from a bowl at random. The first 25 participants whose numbers are selected will be the treatment group, while the other 25 will be the control group.
The characteristics of the two groups
A should be roughly equivalent because both groups will have 25 participants.
B should be roughly equivalent because the participants were labeled and then randomly selected for the groups.
C might not be roughly equivalent because one group may contain people that drink more juice than the other group.
D might not be roughly equivalent because one group may contain more people that prefer a particular juice brand.
Answer:
D might not be roughly equivalent because one group may contain more people that prefer a particular juice brand.Step-by-step explanation:

la velocidad máxima a la que se puede circular en una carretera es el 40 Mi/h ¿cual sería el límite de velocidad en km/h ?
Answer:
El limite de velocidad es [tex]64.37\frac{km}{h}[/tex]
Step-by-step explanation:
Para determinar el limite de velocidad en unidades de km/h es necesario hacer una conversión, esto se puede lograr al aplicar una sencilla regla de tres:
[tex]40\frac{Mi}{h} . \frac{1.6093km}{1Mi}[/tex] ⇒ [tex]64.37\frac{Mi.km}{h.Mi}[/tex] ⇒ [tex]64.37\frac{km}{h}[/tex]
Nota que para poder hacer la conversión es necesario saber a cuanto equivale 1 milla en kilometros (1Mi = 1.6093 km).
Por lo tanto, el limite de velocidad es de [tex]64.37\frac{km}{h}[/tex]

what is the value of x? Show your work
Answer:
180-44 = 136
136÷2= 68
x = 68°
Answer:
x = 68°
Step-by-step explanation:
Since the triangle has 2 congruent sides (23) then the triangle is isosceles and the base angles (x) are congruent, then
x = [tex]\frac{180-44}{2}[/tex] = [tex]\frac{136}{2}[/tex] = 68°

Answer: a= 144. b= 67
Step-by-step explanation:
Angle b and the angle of measure 113 are same side interior angles which sum to 180 (When 2 parallel lines are cut by a transversal, special angles are formed)
113+b=180. Subtract 113 from both sides.
b= 67 degrees
Now that you have b, the interior angles of four sided figures sum to 360.
a+113+67+36=360. Combine like terms.
a+216=360. Subtract 216 from both sides.
a= 144 degrees

Which equation is equivalent to 3/5 = 17 2/5 divided by h
The correct expression will be ( 3 + 9) = ( 87 ÷ h ) + 9. The correct option is C.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the expression is 3 / 5 = 17²/₅ ÷ h. The expression will be solved as below,
3 / 5 = 17²/₅ ÷ h
3/5 = 87 / 5 ÷ h
h = 87 / 3
h = 29
Check option C for the value of h = 29.
3 + 9 = ( 87 / h ) = 9
3 = 87 / h
h = 87 / 3 = 29
Hence. the correct option is C.
