a. The value of x is 7

b. The measure of ∠1 is 99°

<h3>Calculating angles </h3>

From the question, we are to solve for x

From the given diagram, we can write that

m∠NMQ + m∠MQN + m∠QNM = 180° (<em>Sum of angles in a triangle</em>)

From the given information,

m∠NMQ = 5x +19

m∠MQN = 8x -11

m∠QNM = 11x + 4

Then,

5x + 19 + 8x -11 + 11x + 4 = 180

Collect like terms

5x + 8x + 11x = 180 - 19 + 11 - 4

24x = 168

∴ x = 168/24

x = 7

Hence, the value of x is 7

b.
Measure of ∠1 + m∠QNM = 180° (<em>Sum of angles on a straight line</em>)

∴ Measure of ∠1 = 180° - m∠QNM

But m∠QNM = 11x + 4

∴ m∠QNM = 11(7) + 4

m∠QNM = 77 + 4

m∠QNM = 81°

Then,

Measure of ∠1 = 180° - 81°

Measure of ∠1 = 99°

Hence, the measure of ∠1 is 99°

Convert 7 pounds 3 ounces to

svetoff [14.1K]

7 pounds and 3 ounces equal to 3.27 kg

Step-by-step explanation:

We need to convert 7 pounds and 3 ounces to kilograms.

We know:

1 lb = 16 oz

and 1 kg = 2.2 lb

where lb stands for pounds and oz stands for ounces and kg stands for kilograms.

$16\,\,oz = 1\,\,pound\\1\,\,oz = \frac{1}{16} \,\,pound\\3\,\,oz = \frac{1}{16} * 3\,\,pounds\\3\,\,oz = 0.1875\,\,pounds$

So, Total pounds = 7+0.1875 = 7.1875

Now, Converting Pounds to kg

$2.2\,\,pounds = 1\,\,kg\\1\,\,pound = \frac{1}{2.2} \,\,kg\\7.1875\,\,pounds = \frac{1}{2.2} * 7.18757.1875\,\,pounds = 3.27\,\,kg$

So, 7 pounds and 3 ounces equal to 3.27 kg

Makovka662 [10]

Answer:

0.5

Step-by-step explanation:

P(grape or straw) = P(grape) + P(straw) − P(grape and straw)

P(grape or straw) = 0.3 + 0.3 − 0.1

P(grape or straw) = 0.5

If you have 100 entries out of 1200 what are your chances

swat32

100/1200= x/100
cross multiply

(1200 * x)= (100 * 100)

1200x= 10000
divide both sides by 1200

x= 8.333% winning chance

LOSING CHANCE
100% - 8.333%= 91.667%

RATIO OF WINNING TO LOSING
100 tickets= winning chance
1200 total - 100= 1100 losing chance

100:1100
simplify by 100

1:11 odds of winning to losing

ANSWER: The chance of winning is 8.333% and the chance of losing is 91.667% or 1:11.

Hope this helps! :)
