Answer:
B. x = 8√3 ≈ 13.86; y = 8
Step-by-step explanation:
✔️Find x using trigonometric ratio:
Reference angle = 60°
opposite = x
Hypotenuse = 16
Thus:
Sin(60) = x/16
16*sin(60) = x
16*√3/2 = x
8√2 = x
x = 8√3 ≈ 13.86
✔️Find y using Pythagorean Theorem:
y² = 16² - (8√3)²
y² = 256 - 192 = 64
y = √64
y = 8

A right triangle has one leg that is 4 more than twice the other. The area of the triangle is 35. Find the length of the sides.
Answers
Answer:
one leg = 5
other leg = 14
Step-by-step explanation:
let 'x' = length of shorter leg
let '2x + 4' = length of longer leg
A = 1/2bh
35 = 1/2x · 2x + 4
35 = x² + 4
x² + 4 - 35 = 0
(x + 7)(x - 5) = 0
x = -7 and x = 5
We can eliminate -7 as an answer since a length cannot be negative
Answer:
The shorter leg = 5
The longer leg = 14
The hypotenuse = 14.866.....
Step-by-step explanation:
if we represent the smaller leg as "x" we firstly represent the longer leg as...
Longer leg = 2x + 4
(We can do this based on the question)
Now we need to undersstadn t in a right angle triangle the legs can be used as a height and base. So we can make the following equation.
[tex]A_{triangle} = \frac{bh}{2}[/tex]
Substitute the lengths of the legs as based and height and get...
[tex]A_{triangle} = \frac{(2x + 4)(x)}{2}[/tex]
[tex]35 = \frac{2x^{2} + 4x}{2}[/tex]
[tex]35 = x^{2} + 2x[/tex]
[tex]35 = x(x + 2)[/tex]
From here we can see that x = 5.
Therefore the lengths are as follows...
The shorter leg = x = 5
The longer leg = 2(5) + 4 = 14
The hypotenuse = [tex]\sqrt{5^{2} + 14^{2} }[/tex]
The hypotenuse = [tex]\sqrt{5^{2} +14^{2} }[/tex]
The hypotenuse = 14.866.....

The Browns scored 13 more points than the Saints. The total of
their scores was 47. How many points did each team score?
Answers
Answer:
Saints team scores points = 17
Browns team scores point = 30
Step-by-step explanation:
Let Saints team scores points = x
Browns team scores point = y
As given,
The Browns scored 13 more points than the Saints.
⇒ y = x + 13
Now, given
The total of their scores was 47.
⇒ x + y = 47
⇒x + x + 13 = 47
⇒ 2x = 47 - 13
⇒2x = 34
⇒x= [tex]\frac{34}{2}[/tex] = 17
∴ we get
Saints team scores points = x = 17
Browns team scores point = y = x + 13 = 17 + 13 = 30
Answer:
30 , 17
Step-by-step explanation:
browns have x + 13
saints have y
x+13 + x+y = 47
2x = 34
x=17
17 + y = 47
y=30

The perimeter of an equilateral triangle is 114mm.
State the length of one of its sides
Answers
Answer:
Since an equilateral triangle has all three side equal then one of its side is 38mm
The length of one of the sides of the triangle is 38 mm.
What is Perimeter?The perimeter of a form is the space surrounding its edge. Find the perimeter of various forms by summing the lengths of their sides.
Given that all of the sides of an equilateral triangle are equal in length, we may calculate the length of a side by dividing the perimeter by the triangle's total number of sides, which is 3.
As a result, the equilateral triangle's one side has the following length:
114 mm / 3 = 38 mm
Therefore, the equilateral triangle's sides are each 38 mm long.

Answer:

Step-by-step explanation:
180-27-34=119
119 round up to nearest 10 = 120
You look up at 1 but you are not soposed to answer the question by looking at 1, if you have nearest 10 to round then always look at the units.
Always look at the second digit of the nearest number that you would round up.
Example:
round 560 to the nearest 100.
The answer would be 600 because 0-4 goes down and 5-9 goes up,
and in this number 5 goes up so the answer would be rounded up.
If the question said round 560 to the nearest 10 then the answer would be the same because the second digit is 0 and 0 goes down so it does not make any difference. If the second digit goes down then you do not need to change your answer the answer would be the same as the question number.

In a MBS first year class, there are three sections each including 20 students. In the first section, there are 10 boys and 10 girls, in the second section there are 15 boys and 5 girls, and in the third section, there are 12 boys and 8 girls. Five students are selected at random from each group to form committee of 15 students. What is the probability that all the 15 students selected are girls?
Answers
Answer:
[tex]3.52 \times 10^{-9} = 3.52 \times 10^{-7}\%[/tex] probability that all the 15 students selected are girls
Step-by-step explanation:
The selection is from a sample without replacement, so we use the hypergeometric distribution to solve this question.
Hypergeometric distribution:
The probability of x sucesses is given by the following formula:
[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]
In which:
x is the number of sucesses.
N is the size of the population.
n is the size of the sample.
k is the total number of desired outcomes.
Combinations formula:
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
All girls from the first group:
20 students, so [tex]N = 20[/tex]
10 girls, so [tex]k = 10[/tex]
5 students will be selected, so [tex]n = 5[/tex]
We want all of them to be girls, so we find P(X = 5).
[tex]P_1 = P(X = 5) = h(5,20,5,10) = \frac{C_{10,5}*C_{10,5}}{C_{20,5}} = 0.0163[/tex]
All girls from the second group:
20 students, so [tex]N = 20[/tex]
5 girls, so [tex]k = 5[/tex]
5 students will be selected, so [tex]n = 5[/tex]
We want all of them to be girls, so we find P(X = 5).
[tex]P_2 = P(X = 5) = h(5,20,5,5) = \frac{C_{5,5}*C_{15,5}}{C_{20,5}} = 0.00006[/tex]
All girls from the third group:
20 students, so [tex]N = 20[/tex]
8 girls, so [tex]k = 8[/tex]
5 students will be selected, so [tex]n = 5[/tex]
We want all of them to be girls, so we find P(X = 5).
[tex]P_3 = P(X = 5) = h(5,20,5,8) = \frac{C_{8,5}*C_{12,5}}{C_{20,5}} = 0.0036[/tex]
All 15 students are girls:
Groups are independent, so we multiply the probabilities:
[tex]P = P_1*P_2*P_3 = 0.0163*0.00006*0.0036 = 3.52 \times 10^{-9}[/tex]
[tex]3.52 \times 10^{-9} = 3.52 \times 10^{-7}\%[/tex] probability that all the 15 students selected are girls

What is the Volume of a Rectangle?The volume of the rectangle is given by the product of the length of the rectangle and the width of the rectangle and the height of the rectangle
Volume of Rectangle = Length x Width x Height
Volume of Rectangle = Area of Rectangle x Height
Given data ,
To find the volume of the figure, we need to calculate the volumes of the two rectangular prisms separately and then add them together.
The volume of a rectangular prism is given by the formula:
Volume = length x width x height
For the first prism:
Length = 12 centimeters
Width = 9 centimeters
Height = 2 centimeters
Volume of first prism = 12 cm x 9 cm x 2 cm = 216 centimeters³
For the second prism:
Length = 10 centimeters
Width = 9 centimeters
Height = 8 centimeters
Volume of second prism = 10 cm x 9 cm x 8 cm = 720 centimeters³
Now, we add the volumes of the two prisms together to get the total volume of the figure:
216 cubic centimeters + 720 cubic centimeters = 936 centimeters³

Answers
Answer:

Step-by-step explanation:
4x - 2 = 22 - 8x
Move all variables to a single side by adding 8x to both sides of the equation.
4x + 8x - 2 = 22 - 8x + 8x
12x - 2 = 22
Add 2 to both sides to move the constants to one side.
12x - 2 + 2 = 22 + 2
12x = 24
Divide both sides by 12 to isolate the x.
12x / 12 = 24 / 12
