If y varies directly with x and y= 12 when x= 16, what is the value of x when y= 5?

Answers

Answer 1

Answer:

[tex]x = 6 \frac{2}{3} [/tex]

Step-by-step explanation:

Since y varies directly with x,

y= kx, where k is a constant.

① Find the value of the constant k.

When y=12, x= 16,

12= k(16)

16k= 12

[tex]k = \frac{12}{16} \\ k = \frac{3}{4} [/tex]

②Substitute the value of k back into the equation:

[tex]y = \frac{3}{4} x[/tex]

③ Find value of x when y=5.

When y=5,

[tex]5 = \frac{3}{4} x \\ x = 5 \div \frac{3}{4} \\ x = 5 \times \frac{4}{3} \\ x = \frac{20}{3} \\ x = 6 \frac{2}{3}[/tex]

PLS HELP FIND ANGLE MEASUREMENTS

Answers

Answer:

From my observations, AOB looks like an isosceles triangle, so A=18 and B=18. Since a triangle must add up to 180. We do 180-18-18=144. O= 144. Then, triangle BOC looks like an isosceles triangle as well. So, we do 180-144= 36 so O = 36 and then we 180-36=144/2 because two sides have the same angles giving us 72 degrees for angles B and C = 72 and for O= 36

So,

x = 72

y = 36

The angle measures of a triangle are 2y + 3 degrees, 9y – 7 degrees, and 7y + 4 degrees. Which of the following is not one of the angle measures of the triangle?

Answers

Answer:

55

Step-by-step explanation:

The measures of the angles are 23, 83, and 74 degrees. 97 degrees is not the measure one of the angle measures of the triangle option (B) is correct.

What is an angle?

When two lines or rays converge at the same point, the measurement between them is called a "Angle."

It is given that:

The angle measures of a triangle are 2y + 3 degrees, 9y – 7 degrees, and 7y + 4 degrees.

As we know,

The sum of the interior angle of the triangle is 180 degrees

2y + 3 + 9y - 7 + 7y + 4 = 180

18y = 180

y = 10

2y + 3 = 2(10) + 3 = 23 degres

9y - 7 = 9(10) - 7 = 83 degrees

7y + 4 = 7(10) + 4 = 74 degrees

Thus, the measures of the angles are 23, 83, and 74 degrees. 97 degrees is not the measure one of the angle measures of the triangle option (B) is correct.

Monica uso 1,2 litros de leche para hacer 12 flanes iguales ¿cuantos litros de leche necesitaria para hacer 60 flanes? ¿cuantos flanes haria con 0,5 decalitros de leche?

Answers

Answer:

1. 6 L de leche.

2. 50 flanes.

Step-by-step explanation:

1. Determinación del volumen (en litros) necesario para realizar 60 natillas.

De la pregunta dada arriba,

Monica usó 1.2 L de leche para hacer 12 natillas iguales.

Por lo tanto, usará xL de leche para hacer 60 natillas, es decir

xL de leche = (1.2 × 60) / 12

xL de leche = 6

Por lo tanto, necesitará 6 L de leche para hacer 60 natillas.

2. Determinación del número de flanes (natillas) que se pueden producir utilizando 0,5 decalitros de leche.

Empezaremos por convertir 0,5 decalitros (deca) a litro (L).

Esto se puede obtener de la siguiente manera:

1 deca = 10 L

Por lo tanto,

0.5 deca = 0.5 deca × 10 L / 1 deca

0,5 deca = 5 L

Por tanto, 0,5 deca equivale a 5 L.

Finalmente, determinaremos el número de flanes (natillas) que se pueden obtener a partir de 0.5 deca (es decir, 5 L) como se muestra a continuación:

Monica usó 1.2 L de leche para hacer 12 natillas iguales.

Por lo tanto, usará 5 L de leche para producir = (5 × 12) /1.2 = 50 natillas

Por lo tanto, puede hacer 50 flanes (natillas) usando 0.5 deca (es decir, 5 L).

4t =24 - 12

4t =12

t =12 :4

t =3

Answer:

t = 3

Step-by-step explanation:

Original Equation:

4(t + 3) = 24

Use distributive property

4 x t = 4t

4 x 3 = 12

Your equation:

4t + 12 = 24

Subtract 12 from both sides

4t = 12

Divide both sides by 4

t = 3

9. Peyton is collecting data on the lunch habits of students at Hyattsville Middle School. In one class, 14 students bring lunch from home, and 20 buy a school lunch. Hyattsville Middle School has 1700 students. From the data collected, how many students would Peyton predict would buy a school lunch?*​

Answers

Answer: Around 1000 students would buy a schoo lunch.

Step-by-step explanation:

We know that in one class, 14 students bring lunch from home, and 20 buy lunch in the school. This will be our sample.

In total we have 20 + 14 = 34 students, this will be our 100%.

The percentage of students that bring lunch from home can be estimated as the quotient between the number of students that bring lunch from home and the total number of students, times 100%.

p1 = (14/34)*100% = 41.18%

And the percentage of students that buy lunch at school can be computed in the same way:

p2= (20/34)*100% = 58.82%

Then, out of the 1700 students in middle school, we can estimate that around 58.82% of them will buy lunch in the school.

Then the exact number will be:

N = (58.82%/100%)*1700 = 1000

Around 1000 students would buy a schoo lunch.
