Find the measures of x and y.
2.
145°
55°
Answer:
x = 35° , y = 90°
Step-by-step explanation:
the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
145° is an exterior angle of the triangle , then
y + 55° = 145° ( subtract 55° from both sides )
y = 90°
the sum of the 3 angles in a triangle = 180° , then
x + y + 55° = 180°
x + 90° + 55° = 180°
x + 145° = 180° ( subtract 145° from both sides )
x = 35°

of the students who made the honor roll at his school do not exercise.
Using data from the table, explain what is wrong with Miguel's reasoning.
The 63.5% of the students who do not exercise is the wrong percentage because 70% of the students do not exercise.
What is the percentage?The amount of something is expressed as if it is a part of the total which is a hundred. The ratio can be expressed as a fraction of 100. The word percent means per 100. It is represented by the symbol ‘%’.

Andy is building a model train. A train in real life has a wheel diameter of 33 inches, a length of 20 feet, a width of 10 feet, and a height of 12 feet. If his model has a width of 8 inches, what does the height need to be?
By finding and using the scale factor for the model, we conclude that the height of the model is 9.6 inches.
How to apply a scale factor?The ratio between the model's width and the real width is the scale factor, and all the dimensions change following that scale factor.
We have:
8 in = 10ft
1 ft = (8/10) in
This means that each feet in the real life, will be represented with (8/10) inches in the model.
Now we know that the real height is 12ft, then the model's height will be:
12* (8/10) in = 9.6 in
So the correct option is B.

Answer:
y=6x
Step-by-step explanation:
1. find the slope m. Pick two points on the line, such as (0,0) and (1,6). Plug those points into the slope formula.
m=change in y/change in x
m=6-0/1-0 Plug in (0,0)(1,6)
m=6/1 simplify
m=6
The slope is 6
2. Find the y-intercept. Since the line crosses the y-axis at 0, the y-intercept is 0.
3. Use the slope m=6 and the y-intercept b=0 to write the equation in slope-intercept form.
y=mx+b
y=6x+0 Plug in m=6 and b=0
y=6x

Flying against the wind, an airplane travels 2610 kilometers in 3 hours. Flying with the wind, the same plane travels 8750 kilometers in 7 hours. What is the rate of the plane in still air and what is the rate of the wind?
Answer:
200 km/hr
Step-by-step explanation:
Let Va = the velocity of the airplane
Let Vw = the velocity of the wind
When flying with the wind:
(Va+Vw)*(4 hours) = 4000
4Va + 4Vw = 4000
4Vw = 4000 - 4Va
Vw = 1000 - Va
When flying against the wind:
(Va-Vw)*(7 hours) = 4200 km
7Va - 7Vw = 4200
Substitute 1000-Va for Vw and solve for Va:
7Va - 7(1000-Va) = 4200
7Va -7000 + 7Va = 4200
14Va = 11200
Va = 800 km/hr
Rate of wind:
Vw = 1000 - Va = 1000 - 800 = 200 km/hour

Answer:
14 in
Step-by-step explanation:
area cylinder= area of base × height of cylinder
area of cylinder = (pi × radius²) × H
(sub in values )
196×pi = (pi x r²) × 1
(196×pi)/1 = pi × r²
(196×pi)/pi = r²
(pics cancel each other )
then, square root 196= r

If 12(x -7) = -11 then x =?
Answer:
x = 73/12
Step-by-step explanation:
Given:
[tex]\displaystyle \large{12(x-7)=-11}[/tex]
Distribute 12 in x-7:
[tex]\displaystyle \large{12x-84=-11}[/tex]
Add both sides by 84:
[tex]\displaystyle \large{12x-84+84=-11+84}\\\displaystyle \large{12x=73}[/tex]
Divide both sides by 12:
[tex]\displaystyle \large{\dfrac{12x}{12}=\dfrac{73}{12}}\\\displaystyle \large{x=\dfrac{73}{12}}[/tex]
Therefore, the solution is x = 73/12
Answer:
[tex]\large\boxed{\bf\:x = \frac{73}{12} = 6\frac{1}{12} \approx 6.083}[/tex]
Step-by-step explanation:
[tex]12(x - 7) = -11[/tex]
Multiply 12 by x & 7 (distributive property) in the left hand side of the equation .
[tex]12(x-7)=-11\\(12*x)-(12*7)=-11\\12x - 84 =-11[/tex]
Bring -84 to the right hand side of the equation. Then,
[tex]12x = -11 + 84\\12x = 73\\x=\frac{73}{12} \\\\\boxed{\bf\:x = \frac{73}{12} = 6\frac{1}{12} \approx 6.083}[/tex]

What is the largest circle contained in a triangle where the center of the circle is the incenter of the triangle?
Answer:
In geometry, the incircle or inscribed circle of a triangle is the largest circle contained in the triangle; it touches (is tangent to) the three sides. The center of the incircle is a triangle center called the triangle's incenter.
Triangle A B C is shown. Side A C has a length of 27. Side C B has a length of 54.
Based on the diagram, which expresses all possible lengths of segment AB?
AB = 25
27 < AB < 81
AB = 85
AB< 27 or AB > 81
Answer:
27<AB<81
Step-by-step explanation:
The sum of two sides of a triangle have to be than the length of the third side. 27+54 is 81, so the AB has to be less than 81. Now, to find the minimum, I can say 27+x has to be greater than 54, so x has to be greater than 27. Therefore, the answer has to be between 27 and 81, so the 2nd one is correct.

B. 27 < AB < 81

The sales of new products over time are found to follow a quadratic model before dropping off to zero at the end of the product’s lifetime. A new product is released with sales modeled by the equation
S
=
−
(
t
−
3
)
2
+
81
, where S represents the sales in millions of dollars and t represents the number of years the product will be sold. According to the equation, what will be the lifetime of this product?
The sales equation of the product is an illustration of a quadratic function, and the lifeline of the product is 12 years
How to determine the lifeline of the product?The sales equation is given as:
S(t) = -(t - 3)² + 81
The lifeline of the product is when the sales hits 0.
This means that S(t) = 0
So, we have:
-(t - 3)² + 81 = 0
Subtract 81 from both sides
-(t - 3)² = -81
Divide both sides by -1
(t - 3)² = 81
Take the square root of both sides
t - 3 = 9
Add 3 to both sides
t = 12
Hence, the lifeline of the product is 12 years
