La temperatura de un congelador bajó de 3 °C a −9 °C en 3 horas. Si la temperatura del congelador bajó en la misma cantidad de grados cada hora, ¿qué temperatura tenía el congelador al completarse la primera hora?
Answers
Usando proporciones, se encuentra que al final de la primera hora, el congelador tenía una temperatura de -1ºC.
Este problema se resuelve por proporciones. En 3 horas, la temperatura bajó 12ºC, puesto que [tex]3 - (-9) = 12[/tex].La temperatura del congelador bajó en la misma cantidad de grados cada hora, o sea, en la primera hora, la cantidad que bajo es:
[tex]\frac{12}{3} = 4[/tex]
4ºC bajo a 3ºC es:
[tex]3 - 4 = -1[/tex]
O sea, al final de la primera hora, el congelador tenía una temperatura de -1ºC.

C.Triangle 5 has a 80 degree angle and a 30 degree angle, and Triangle 7 has a 70
degree angle
D.Triangle 7 has 2 50 degree angle, and Triangle 8 has a 50 degree angle and a 100
degree angle
Answers
Answer:
Step-by-step explanation:
This question involves the concept of similar triangles.
The pair of triangles that are similar are "B and D".
A pair of triangles is termed as similar triangles if the two angles of both the triangles are equal to each other. Hence, we will check this condition for each pair given in the question.
A.
Only one angle is given to be equal for both the triangles, while the other two angles are unknown. Hence, this pair can not be termed as similar.
B.
For an isoceles triangle, two sides and two angles of the triangle are equal. Considering the 40° angle to be the equal angle, we can safely conclude that the two angles of both the triangles in the pair are the same. Hence, this pair can be termed as similar.
C.
Triangle 5 has angles: 30°, 90° and (180°-30°-90°) = 60°. While triangle 6 has angles: 30°, 70°, and (180°-70°-30°) = 80°. Since all the angles of both the triangles are different. Therefore, they can not be termed as similar.
D.
Triangle 7 has angles: 50°, 20° and (180°-50°-25°) = 105°. While triangle 6 has angles: 50°, 105°, and (180°-50°-105°) = 25°. Since all the angles of both the triangles are equal. Therefore, they can be termed as similar.

3y + 15 = 2x + 15 =
Answers
Answer:
x = 3/2y
y = 2/3x
Step-by-step explanation:
x = 3/2y
Swap sides so that all variable terms are on the left hand side
2x + 15 = 3y + 15
Subtract 15 from both sides
2x = 3y + 15 - 15
Subtract 15 from 15 to get 0
2x = 3y
Divide both sides by 2
2x/2= 3y/2
Dividing by 2 undoes the multiplication by 2
X = 3y/2
Y = 2/3x
Subtract 15 from both sides
3y = 2x + 15 - 15
Subtract 15 from 15 to get 0
3y = 2x
Divide both sides by 3
3/3y = 2/3x
Dividing by 3 undoes the multiplication by 3
y = 2/3x

Sheila buys two concert tickets from her friend. She pays $90 for the two tickets. She looks at the tickets and sees that each ticket has a face value of $52.50.
Part A: How much of a markdown did her friend give Sheila?
Part B: What was the percent markdown, rounded to the nearest whole percent?
Answers
Answer:
$15
I don't know the percentage.
Step-by-step explanation:
50 + 50 = 100, 2 + 2 = 4, .50 + .50 = 1
100 + 4 = 104 + 1 = 105
100 - 90 = 10 plus the 5 left-over = 15

110° = ∠AED
Step-by-step explanation:
Four sides polygon. The sum of the angles = (n - 2)180; 4 - 2(180) = 360°
∠B + ∠D + ∠BCD + ∠DEB = 360°
92° + 98° + 86° + ∠DEB = 360°
276° + ∠DEB = 360°
∠DEB = 360° - 276°
∠DEB = 84°
Now ∠AEB + ∠BED + ∠AED = 360° All exterior angles of any polygon = 360°
166° + 84° + ∠AED = 360°
250° + ∠AED = 360°
110° = ∠AED

help me pls asap thank you
Answers
I think you shouldn't memorize any formula to solve it. But you should know that on the fahrenheit thermometer freezing point is 32 and the boiling point is 212. And in celcius, it is 0 and 100. So we can make the inference that changing 100 units in celcius corresponds to a change of 180 units in fahrenheit. Thus, we should ask that if celcius increase from 0 to 200, what would happen to fahrenheit.
Basic math:
While celcius increase 100, fahrenheit increase 180,
While celcius increase 200, fahreinheit increase 360.
And you shouldn't forget that fahrenheit's freezing point is 32.
32+increase(360)=392
A contractor is roofing a house. The contractor considers a roof to be steep when the roof rises 5 in., or more, for every
12 in, it runs. The following graph is a model of how steep the roof is. Does the contractor believe the roof is steep, and
what is the slope of the roof?
Answers
Using the slope, it is found that the correct option is:
No, the contractor does not believe the roof is steep because the slope is 0.
Given two points, [tex](x_0, y_0)[/tex] and [tex](x_1, y_1)[/tex], the slope is given by change in y divided by change in x, that is:
[tex]m = \frac{\Delta_y}{\Delta_x} = \frac{y_1 - y_0}{x_1 - x_0}[/tex]
The slope measures the inclination of a graph, and if it is zero, the graph is not steep.In this problem, y is always the same value, hence [tex]\Delta_y = 0[/tex] and [tex]m = 0[/tex], which means that the roof is not steep, and the correct option is:
No, the contractor does not believe the roof is steep because the slope is 0.

Answers
Step-by-step explanation:
y directly proportional to X
y=kx
when k is constant
y is 25 and X is 120
25=k120
divide both sides by 120
25/120
k=25/120
there fore the law connecting is 25/120
what is the value of y when x = 72? 25/120*72=3

Step-by-step explanation:
all you need to do is multiply the numerator and denominator of the fraction 4/9 by 2. the numerator being the top number of 4 and the denominator being the bottom number of 9. just multiply the numbers by 2 in order that 4 becomes 8. remember whatever you do to the top you do to the bottom as well. so then you need to multiply the denominator 9 by 2 to become 18. just add the two numerators 8 and 9 to have 17 and since you're adding denominators it's going to remain 18. so now you have 17 over 18 or seventeen eighteenths.
