Answer:
12 pet
Step-by-step explanation:
6 of Daniel pets are birds, that is chicken and Parrot.
But, Daniel has 2 parrots, therefore the number of chickens = 6 - 2 = 4. He has 4 chickens.
The number of chicken = number of goldfish - 1; number of goldfish = number of chicken + 1, hence number of goldfish = 4 + 1 = 5
Number of goldfish = number of turtles + 4; number of turtles = number of goldfish - 4 = 5 - 4 = 1.
Therefore total number of pets = Parrot + chicken + goldfish + turtles = 2 + 4 + 5 + 1 = 12
Daniel has 12 pets
6 PERSONAS DEBEN VIAJAR EN UN AUTO DE 7 PASAJEROS. PERO SOLO 3 SABEN MANEJAR, DE CUANTAS MANERAS DIFERENTES SE PUEDEN ACOMODAR?
Answer:
3C1 * 7C6 * 3C2 * 3C3
Step-by-step explanation:
Dado que solo tres saben cómo conducir, de estos tres uno estará en la posición de conducción, por lo tanto, el número de formas en que este conductor puede elegir entre estos tres es 3C1 * 7C6
Ahora, 2 de los conductores se sentarán en los asientos de los pasajeros junto con otros tres 3C2 * 3C3
Número total de oportunidades = 3C1 * 7C6 * 3C2 * 3C3
4.Beyunka is creating a diagram to prove that a certain triangle is a right triangle.

diagram could be the one that Beyunka is creating?
Option 'D' is the correct option.
The correct diagram for Beyunka creating is given in option D.
What is Right triangle?
When an angle of a triangle is measure 90 degree then the triangle is called a right triangle.
Given that;
Beyunka is creating a diagram to prove that certain triangle is a right triangle.
Since, The right triangle is satisfy the Pythagoras theorem.
Now, By option D;
Let sides of a triangle are,
Hypotenuse (H) = c
Perpendicular side (P) = a
Then, The base of the right triangle = √H² - P² = √c² - a²
And, All other diagrams are not satisfy the Pythagoras theorem.
Thus, The correct diagram for Beyunka creating is given in option D.

Answer:
50°
Step-by-step explanation:
The sum of the internal angles of a triangle is always 180°. The PQR triangle have 70° + 60° = 130°, so it need to have more 50° to complete 180°, and the angle x have the same size that this "missing angle" from the PQR triangle because the angle x is formed by the same segments, so it have 50°

Which equation represents the graphed function? O y = -3x + 3 O y = 3x - 3 O y = 3x - 2 / 2 O y=-*x+3
Answer:
y=1/3x+3
Step-by-step explanation:
the general equation for a straight line is y=mx+c.where c is the y cut therefore the y cut on our graph is at (0,3)therefore c is 3
we then find the gradient which is "m" on our equation using the formula m=y2-y1/x2-x1
then we substitute the m and c then tha is the equation.

Anthony has to practice his guitar for 1.75 hours each morning and 2.5 hours each evening for the first 4 days this week. How many hours has Anthony practiced this week?
Answer:
17 hours
Step-by-step explanation:
From the above question,
Anthony is practicing 4 days in a week
Hence
The number of hours he practices in the morning for 4 days =
1.75 hours × 4
= 7 hours
The number of hours he practices in the evening for 4 days =
2.5 hours × 4
= 10 hours
Therefore, the total number of hours he practices this week
= 7 hours + 10 hours
= 17 hours

Answer:
The parallel sides are called the bases of the trapezoid
Step-by-step explanation:

[tex]= \frac{14.1+22.7}{2} \times 18\\\\=331.2 \ unit^2[/tex]
Answer:
331.2 units^2
Step-by-step explanation:
There is a formula for the area of a trapezoid of legs a and b and width h:
a + b
----------- * h
2
Here the leg lengths (which are parallel) are 14.1 and 22.7, and the width is 18. Thus, the desired area is
14.1 + 22.7 36.8
---------------- * 18 = A = ------------ * 18 = 331.2 units^2

wjat are the x intercepts if y=x squared minus 100
Answer:
x = ± 10
Step-by-step explanation:
Given
y = x² - 100 ← a difference of squares , that is
y = x² - 10² = (x - 10)(x + 10)
To find the x- intercepts let y = 0 , that is
(x - 10)(x + 10) = 0
Equate each factor to zero and solve for x
x - 10 = 0 ⇒ x = 10
x + 10 = 0 ⇒ x = - 10

find the distance between each pair of points
(7 1/2, 3 1/4) and (7 1/2, 9 1/2)
Answer:
d=13
Step-by-step explanation:
D = √(x2 - x1)2 + (y2 - y1)2
D = √(-6 - (-8))2 + (1 - 4)2
D = √(-6 + 8)2 + (-3)2
D = √(2)2 + (-3)2
D = √4 + 9
D = √13

Plot 3 points with integer coordinates that fall on the graph of the function y=x+4
Where should I plot it?
Answer:
(0, 4)
(1, 5)
(-1, 3)
Step-by-step explanation:
the function is already in slope-intercept form (y=mx+b). B is the y intercept and mx is the slope. The equation y=x+4 means that there is a y intercept of 4 and a slope of 1. So, y intercept is when x is equal to 0 which means one of your points will be (0,4). The next point will be 1 unit up and 1 unit to the right of the point (0, 4) and the third point will be 1 unit down and 1 unit to the left of (0, 4). This gives you the points (1, 5) and (-1, 3)

A manufacturer wants to design a container with a volume of 800 cubic centimeters. Their old container is shown
Answer:
2.05 cm
Step-by-step explanation:
3.14× (n+3)²×10 = 800
31.4(n+3)²=800
(n+3)²= 800/31.4
(n+3)²= 25.48
n+3 =√25.48
n+3= 5.05
n = 5.05 -3 = 2.05
so, the radius should be increased :
2.05 cm

using cos rule
cos 60=adjacent/hypotenuse
1/2=80/x(do cross multiplication)
80*2=x
160=x
Answer:
x = 160
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos60° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{CD}{CE}[/tex] = [tex]\frac{80}{x}[/tex] ( multiply both sides by x )
x × cos60° = 80 ( divide both sides by cos60° )
x = [tex]\frac{80}{cos60}[/tex] = 160

Money in a bank triples every 9 years. If $100 is deposited today, what will it's value be after 36 years?
Answer:
[tex]\$8,100[/tex]
Step-by-step explanation:
We can denote this increase with the function [tex]y=3^x\cdot 100[/tex], where [tex]y[/tex] is value after [tex]\frac{x}{9}[/tex] years.
Substituting [tex]x=36[/tex], we get:
[tex]3^4\cdot 100=\boxed{\$8,100}[/tex]
Answer:
8,100
Step-by-step explanation:
The first 9 years would be 300, then 18 years would be 900, and 27 years it would be 2,700, and finally after 36 years it would be 8,100.
