Since the triangle is equilateral, QR = RS = QS.
a. MS = (1/2)74
MS = 37
b. Half of the equilateral triangle makes a right triangle. Use Pythagorean Theorem to find QM.
a^2 + b^2 = c^2
37^2 + b^2 = 74^2
1369 + b^2 = 5476
subtract 1369 from both sides
b^2 = 4107
take the square root if both sides
b = 64.1
QM = 64.1

Un camarero tiene que repartir 2 botellas de 3/4litros entre 3.¿Que fraccion de litro le tocará a cada uno

vekshin1

Respuesta:

1/2 litros

Explicación paso a paso:

Dos botellas de 3/4 litros:

Litros totales = 2 * 3/4 = 6/4 litros

Número de personas entre las que se dividirá = 3

Fracción que cada uno obtendrá:

Litros totales / número de personas

= (6/4) ÷ (3)

= 6/4 * 1/3

= 6/12

= 1/2 litros

Write the equation of the circle that has a center of (-7, 17) with a radius of V19.

kipiarov [429]

I think your question seems to be :-

Write the equation of the circle that has a center of (-7, 17) with a radius of √19

So , as we know that the equation of circle with centre at (h,k) and radius r is given by ${\bf{(x-h)^{2}+(y-k)^{2}=r^{2}}}$ . Now , using same concept in this question ;

${:\implies \quad \sf \{x-(-7)\}^{2}+(y-17)^{2}=(\sqrt{19})^{2}}$

${:\implies \quad \bf \therefore \quad \underline{\underline{(x+7)^{2}+(y-17)^{2}=19}}}$

This is the required equation of Circle

Simplify the expression (2sqrt27) x (3sqrt32)

mars1129 [50]

The first step for solving this expression is to simplify the radical in the first set of parenthesis.
(6 $\sqrt{3}$ ) × (3 $\sqrt{32}$ )
Simplify the radical in the second set of parenthesis.
(6 $\sqrt{3}$ ) × (12 $\sqrt{2}$ )
Remove the parenthesis off of both sets.
6 $\sqrt{3}$ × 12 $\sqrt{2}$
Now calculate thee product to find your final answer.
72 $\sqrt{6}$
This means that the correct answer to your question is going to be 72 $\sqrt{6}$ ,, or option B.
Let me know if you have any further questions.

What is the smallest integer that can be divided by the product of a prime number and 7 while yielding a prime number?

11111nata11111 [884]

Answer:

(D). 28

Step-by-step explanation:

We have been given that the smallest integer that can be divided by the product of a prime number and 7 while yielding a prime number.

We know that smallest prime is 2. The product of 2 and 7 is 14.

Let us divide our given numbers by 14.

(A) 7.

$\frac{7}{14}=\frac{1}{2}$

The quotient is not a integer or prime number.

(B). 14

$\frac{14}{14}=1$

We know that 1 is not a prime number.

(C) 24.

$\frac{24}{14}=\frac{12}{7}$

The quotient is not a integer or prime number.

(D). 28

$\frac{28}{14}=2$

Since 2 is a prime number, therefore, 28 is the smallest integer that can be divided by the product of a prime number and 7 and yield a prime number.
