Answer: 3.6

We have a diameter of 12 so a radius of 6.

The chord makes a right angle with a different diameter, which bisects the chord, so each piece is 4.8.

x is the remaining leg. Let's write 4.8=4(1.2) and 6=5(1.2) so this is a 3/4/5 right triangle, x= 3(1.2) = 3.6

1. Find the distance from point P to QS

12345 [234]

Answer:

5.7 units

Step-by-step explanation:

The distance from point P to QS is the distance from point P (1, 1) to the point of interception R(-3, 5).

Use distance formula to calculate distance between P and R:

$PR = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

Let,

$P (1, 1) = (x_1, y_1)$

$R(-3, 5) = (x_2, y_2)$

Plug in the values into the formula.

$PR = \sqrt{(-3 - 1)^2 + (5 - 1)^2}$

$PR = \sqrt{(-4)^2 + (4)^2}$

$PR = \sqrt{16 + 16}$

$PR = \sqrt{32}$

$PR = 5.7 units$ (to nearest tenth)

What is 5/6 y - 8 = 2 a. 12 b. 8 1/3 c. -7 1/5 d. 13

inn [45]

Answer:

$a.\ 12$

Step-by-step explanation:

$\frac{5}{6}y-8=2\\\\Add\ 8\ both\ sides\\\\\frac{5}{6}y-8+=2+8\\\\\frac{5}{6}y=10\\\\Multiply\ by\ 6\ both\ the\ sides\\\\\frac{5}{6}y\times 6=10\times 6\\\\5y=60\\\\divide\ by\ 5\ both\ the\ sides\\\\\frac{5y}{5}=\frac{60}{5}\\\\y=12$

In a survey , rajveer asked 110 people whether they were employed or unemployed.

storchak [24]

Answer:

Step-by-step explanation:

Create a two-way table with the given information:

$\begin{array}{| c | c | c | c |}\cline{1-4} & \sf Employed & \sf Unemployed & \sf Total\\\cline{1-4} \sf Men & 40 & & 59 \\\cline{1-4} \sf Women & & & \\\cline{1-4} \sf Total & 84 & & 110 \\\cline{1-4} \end{array}$

Fill in the blanks in the table using mathematical operations:

⇒ Men unemployed = 59 - 40 = 19

⇒ Women employed = 84 - 40 = 44

⇒ Total women = 110 - 59 = 51

⇒ Total unemployed = 110 - 84 = 26

⇒ Women unemployed = 51 - 44 = 7

$\begin{array}{| c | c | c | c |}\cline{1-4} & \sf Employed & \sf Unemployed & \sf Total\\\cline{1-4} \sf Men & 40 & 19 & 59 \\\cline{1-4} \sf Women &44 & 7& 51 \\\cline{1-4} \sf Total & 84 &26 & 110 \\\cline{1-4} \end{array}$

Reading from the table, 7 women responded that they were unemployed.

Two numbers are 10 units away in different directions from their midpoint, m, on a number line. The product of the numbers is –9

irinina [24]

In my opinion the answer is m2 – 100 = –99
proof
m2 – 100 =(m – 10)(m + 10)
for eg. m=1, (-9)(11)= –99
