Answer:
First one : 53/100 and 53%
Step-by-step explanation:
0.53 --> 53/100 --> 53%
Answer:
0.53=53/100=53%
Step-by-step explanation:
The decimal equivalent of the unknown percentage is evaluated by moving the decimal 2 places to the left from its current position.
To convert it to an equivalent fraction replace the % sign with x1/100 and simplify:53*1/100
Divide out the common factor to simplify 53/100

C
Work out length AC.pythagoras
Answer:
11.7 cm
Step-by-step explanation:
Using Pythagoras Theorem
AC² = AB² + BC²
AB = 4 cm
BC = 11 cm
AC² = 4² + 11²
AC = √4² + 11²
AC =✓137
AC = 11.704699911 cm
Approximately = 11.7 cm
Length AC = 11.7cm
Find the size of the angle using Sohcahtoa or Pythagoras.
Answer:
x ≈ 38.7°
Step-by-step explanation:
Using the sine ratio in the right triangle
sinx = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{5}{8}[/tex] , then
x = [tex]sin^{-1}[/tex] ([tex]\frac{5}{8}[/tex] ) ≈ 38.7° ( to 1 dec. place )
a box of chocolates contains four milk chocolates, four dark chocolates, and three white chocolates. you randomly select one chocolate. what is the probability that it is a milk or dark chocolate? (fractions)
a. 7/11
b. 16/121
c 4/11
d. 8/11
Answer:
D
Step-by-step explanation:
4+4=8 probability of success
4+4+3=11 total senario
therefore 8/11 is your probability of a success
A box of chocolates contains four milk chocolates, four dark chocolates, and three white chocolates. The probability that it is milk or dark chocolate is 8/11.
What is the probability?Probability refers to a possibility that deals with the occurrence of random events. The probability of all the events occurring need to be 1.
P(E) = Number of favorable outcomes / total number of outcomes
The total number of milk chocolate = 4
The total number of dark chocolate = 4
The total number of white chocolate = 3
The total number of milk or dark chocolate = 8
Total number of chocolate a box contains = 11
The probability that it is a milk or dark chocolate = 8/11

Answer:
164 degrees
Step-by-step explanation:
The measure of the individual internal angle in a polygon is;
(n-2)180/n
n = 22
So we have;
(22-2)180/22
= (20 * 180)/22
= 163.64 degrees
To the nearest whole number, this is 164

There are two bags containing only yellow and orange marbles. Bag A has 9 yellow marbles and 3 orange marbles. Bag B has 7 yellow marbles and 13 orange marbles. A marble is randomly chosen from each bag. List these events from least likely to most likely. Event 1 : choosing a yellow or orange marble from Bag B. Event 2 : choosing a red marble from Bag A. Event 3 : choosing an orange marble from Bag B. Event 4 : choosing a yellow marble from Bag A.
Answer:
Event 2, Event 3, Event 4, Event 1
Step-by-step explanation:
The probability of Event 2 occurring is 0/12(0%) as there are no red marbles in the bag.
The probability of Event 3 occurring is 13/20(65%) as you will get an orange marble from Bag B 13 out of 20 times.
The probability of Event 4 occurring is 9/12(75%) as you will get a yellow marble from Bag A 9 out of 12 times.
The probability of Event 1 occurring is 20/20(100%); therefore you will always get either a yellow or an orange marble from Bag B.

  hurry please! 20 points. Find the measure of angle θ. Round your answer to the nearest tenth place.
Answer:
Angle θ would be about 17.1 degrees.
Step-by-step explanation:
To figure out what Angle θ is, first we have to find the hypotenuse. You can easily do that by find the square root of BC² + AC².
c = √4² + 13²
Square 4 and 13 to get 16 and 169 respectively.
c = √16 + 169
Add 16 and 169 to get 185.
c = √185
Find the square root of 185 (I'll round to the nearest tenth.)
c = 13.60147 ≈ 13.6 units
To find angle β, divide AC by AB and find the inverse sine of that.
β = arcsin(13/13.6)
Divide 13 by 13.6. Round to the nearest thousandth.
β = arcsin(0.955)
β ≈ 1.2723 rad
To convert radians to degrees, multiply the radians by 57.2957795 for an approximate amount.
β ≈ (1.2723 * 57.2957795)°
β ≈ 72.8974203 ≈ 72.9 degrees
Now subtract 72.9 from 90 to get angle θ's measure of 17.1 degrees.

Answer:
m∠T = 45°
Step-by-step explanation:
The sum of angles in a triangle is 180°, so ...
(2x +10)° +(3x -9)° +(6x -19)° = 180°
11x -18 = 180 . . . . . collect terms, divide by °
11x = 198 . . . . . . . . add 18
x = 18 . . . . . . . . . . . divide by 11
Then the angle of interest is ...
m∠T = (3x -9)° = (3·18 -9)°
m∠T = 45°
_____
The other angles are ...
m∠S = 46°
m∠U = 89°

What is the correct translation of "3 more than a number times 2"?
answers: 2n + 3, 3+ 2n
Answer:
2n+3
Step-by-step explanation:
Since the question is asking for "a number" times 2, the first thing that is necessary in any expression is 2n. Next, since there is "3 more", 3 must be added to the 2n. Combining this gives the translation 2n+3.
