The value of y is directly proportional to the value of x. If y = 25 when x = 120, what is the value of y when x = 72?
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
therefore y is 3

Answer:
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
GIVING POINTS PLEASE HELP)Which of the following is true?
thirteen eighteenths
seventeen eighteenths
thirteen ninths
seventeen ninths
Answer:
seventeen eighteenths
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.

Step-by-step explanation:
50 + 50 = 100, 2 + 2 = 4, .50 + .50 = 1

Which pair of triangles must be similar?
A.Triangles 1 and 2 are equilateral.
B.Triangles 3 and 4 each have an 80 degree angle.
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
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.

Histograms are used to represent data using bars
The dataset is given as:

Rearrange in ascending order

Calculate the range
[tex]\mathbf{Range = 18 - 3}[/tex]
[tex]\mathbf{Range = 15}[/tex]
Using 4 classes, the class width is
[tex]\mathbf{Width = \frac{Range } 4}[/tex]
[tex]\mathbf{Width = \frac{15} 4}[/tex]
[tex]\mathbf{Width = 3.75}[/tex]
Approximate
[tex]\mathbf{Width = 4}[/tex]

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?
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.

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?
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:

3y + 15 = 2x + 15 =
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

Which rational number equals 0 point 6 with bar over 6? (5 points) a 2 over 3 b 6 over 10 c 4 over 5 d 6 over 5
9514 1404 393
Answer:
a. 2/3
Step-by-step explanation:
The bar over the 6 means the digit is repeated indefinitely. A bit of algebra can turn a repeating decimal into a fraction. Let x represent the value of the repeating decimal.
[tex]x=0.6\overline{6}\\\\10x=6.6\overline{6}\\\\10x-x=6.6\overline{6}-0.6\overline{6}\\\\9x=6\\\\x=\dfrac{6}{9}=\boxed{\dfrac{2}{3}}[/tex]

The attachment shows the long division of 2/3 gives a repeating decimal with a repeating digit of 6. You can tell the quotient repeats when the new dividend (after subtraction) is equal to a dividend you have seen before. In this case, the dividend is repeatedly 20, and the quotient digit is repeatedly 6.
The point of the long division is to show you that 2/3 is the correct answer choice for a rational number equivalent to 0.666...(repeating).
