Determine whether the conclusion is valid AND explain. You want to know how the residents of your town feel about building a new baseball stadium. You randomly survey 100 people who enter the current stadium. Eighty support building a new stadium, and twenty do not. So, you conclude that 80% of the residents of your town support building a new baseball stadium.
Answer: The answer is valid, because you survey 100 people and 80 of them support building a new stadium.
Step-by-step explanation:
80% agree. 80/100 = 80%

Given triangle ABC is similar to triangle DEF, angle A measures 30 degrees, and angle F measures 50 degrees, what is the measure of angle B?
Answer:
100 degrees
Step-by-step explanation:
Since triangle ABC is similar to triangle DEF, their angles are basically the same.
All angles of a triangle have to add up to 180.
We are already given two angles: 30 and 50
Add them together: 30 + 50 = 80
Now we subtract the number from 180
180 - 80 = 100
The remaining angle has to be 100 degrees
(1) D. Generalize Explain your procedure for calculating the profit
for Grooming USA. Suppose you wanted to calculate the profit
for several different scenarios. How could you simplify your
process?
Answer:
$1,650 profit
Step-by-step explanation:
It cost $15 to groom one animal, if you groom 95 animals you would do 95 animals x $15 = $1,425 profit. If you groom 110 animals and charge $15 per animal you would do the same equation. 110 animals x $15 = $1,650. The equation for this problem is the number of animals groomed X the cost to groom one animal.

What is the value of the expression 6 3y if x = 5 and y = -1 ?
Answer: The answer to this equation is 33
Step-by-step explanation:
Well, let's plug the numbers in.

Explanation:
Steve correctly computed the change in x to be 2, and the change in y to be 6. However he put 2 in the slope formula for Δy (the change in y), and 6 for Δx. That is, Steve reversed the values of Δx and Δy.
The actual slope is ...
slope = Δy/Δx = 6/2 = 3

If the area of therectangular billboard covered by the ribbon was approximately 4200 square feet, and the width of the billboard was approximately 60 feet, what
was the height of this billboard?
Answer:
The answer is 70 feet
Step-by-step explanation:
Given;The area of therectangular billboard covered by the ribbon was approximately 4200 square feetThe width of the billboard was approximately 60 feet.To Find;The height of this billboard = ?Formula;Area = Width × HeightHere, We know the area so,
Area = Width × Height
Height = Area ÷ Width
H = 4200 ÷ 60 feet
H = 70 feet
Thus, The height of the billboard is 70 feet

if she started with 6, the first point you would put is (0,6)
this is how the equation would look:
y=___+6
(Tip: the number on the right is the y-intercept and the one on the left is the slope)
Now to find the slope: m=
y-y / x-x
Let’s use points (0,6) and points (2,8)
Rewrite to find slope: 8-6 / 2-0 = 2/2 or 1
Now the equation should be:
y=1x+6

What is a quadratic equation?"A quadratic equation is an algebraic equation of the second degree in 'x'. The quadratic equation in its standard form is ax² + bx + c = 0, where 'a'(a ≠ 0) and 'b' are the coefficients, 'x' is the variable, and 'c' is the constant term."
The solution of the first equation in the system is (- 3, - 3).
Therefore, the equation will be
[x - (- 3)] [x - (- 3)] = 0
⇒ (x + 3)(x + 3) = 0
⇒ (x + 3)² = 0
⇒ x² + 6x + 9 = 0
The solution of the second equation in the system is (3, - 3).
Therefore, the equation will be
[x - 3] [x - (- 3)] = 0
⇒ (x - 3)(x + 3) = 0
⇒ (x)² - (3)² = 0
⇒ x² - 9 = 0

The sum of 2 numbers is 15 and their qoutient is 2
x + y = 15------(1)
x/y = 2------(2)
y = 15 - x
put this value in eq 2
x/(15-x) = 2
x = 2 (15 - x)
x = 30 - 2x
2x + x = 30
3x = 30
x = 10
y= 15 - x
y = 15 - 10
y = 5
Solution:
Given:
x + y = 15x/y = 2Let’s simplify the second equation to find out the value of x.
x/y = 2 x = 2yNow, let’s substitute the value of x into the first equation.
x + y = 152y + y = 153y = 15y = 5Now, let’s substitute the value of y into the simplified second equation.
x = 2yx = 2(5)x = 10Hence, the value of x and y are 5 and 10 respectively.

3. Luis wants to calculate the volume of his globe. The globe is in the shape of a sphere, as represented in
the picture. He measured the circumference of the globe along the equator to be 72 inches.
Which of the following measures is closest to the volume of Luis's globe?
The measure which is closest to the volume of Luis's globe is; 6301.2in³
Volume of a sphereIf the circumference of the globe along the equator is 72inches along the equator;
C = 72 = 2π× rHence, the radius of the globe can be evaluated as;
r = 72/(2×3.14)r = 72/6.28r = 11.46in.
On this note, the Volume, V of the globe is;
V = (4/3) × π × r³V = (4/3) × 3.14 × 11.46³V = 6301.2in³
