if cos=5 by 13 find the value of sin
Answer:
The value of sin is : 12/13
Step-by-step explanation:
The formula for cosine of an angle is the length adjacent to that angle divided by the hypotenuse.
This means if ;
cos∅ = A/H
then using this information and given that;
cos ∅ = 5 by 13
cos ∅ = 5/13
You can find the opposite side length from Pythagorean relationship as;
13²-5²=b²
144 = b²
√144 = b
12 = b
Opposite side length = 12
Sin ∅ = opposite side length / hypotenuse
Sin ∅ = 12/13

Answer:
x = 24
y = 8√3
Step-by-step explanation:
This is a special right triangle with angle measures 30° 60° 90°
The side length that sees 90° is represented by 2a, the side length that sees angle 60° is represented by a√3 , and the side length that sees angle 30° is represented by a
16√3 ÷ 2 = 8√3 this is the value of y
8√3 × √3 = 24 this is the value of x

Out of 150 students at JHS 190, 48 had Calamari for lunch. What percent had Calamari for lunch?
Answer: 32%
Step-by-step explanation:
From the question, we are informed that out of 150 students at JHS 190, 48 had Calamari for lunch.
The percent that had Calamari for lunch would be calculated as:
= Number of students that had Calamari / Total students at JHS 190 × 100
= 48/150 × 100
= 32%

A cylinder has a radius of 3 cm and a height of 25 cm. We fill the cylinder with water to a height of 15 cm. Then we add 5 golf balls to the water. Each golf ball has a radius of 2.2 cm. What will the new height of the water be?
Answer:
The new height of the water will:
[tex]H_{new}=22.89 cm[/tex]
Step-by-step explanation:
The submerged volume due to an object in a liquid, water in our case, is equal to the displaced volume of the water, it is the Archimedes principle.
The volume of a golf ball (sphere) will be
[tex]V_{ball}=\frac{4}{3}\pi r^{3}=\frac{4}{3}\pi 2.2^{3}[/tex]
[tex]V_{ball}=44.6 cm^{3}[/tex]
We have 5 golf balls, so the total volume will be:
[tex]V_{5-ball}=5*44.6 cm^{3}=223\: cm^{3}[/tex]
Using Archimedes' principle the extra volume of water will be 223 cm³
Now, we know that the cylinder has a radius of 3 cm, then the height related to 223 cm³ will be:
[tex]223=\pi r^{2}h[/tex]
[tex]223=\pi 3^{2}h[/tex]
[tex]h=7.89\: cm[/tex]
Therefore, the new height of the water will:
[tex]H_{new}=15+7.89=22.89 cm[/tex]

A linear function plot is shown below. The plot represents a function of the form Y = mX + b where m represents the slope of the plot line and b represents the intercept. Determine m and b from the plot. If X = –3.5, calculate the value of Y and enter it in the box with one digit to the right of the decimal point.
A linear plot is used to represent straight line equations. From the plot, we have the following:
The slope (m) is -2The intercept (b) is 3The value of y when [tex]x = -3.5[/tex] is 10From the plot (see attachment), we have the following coordinate points
[tex](x_1,y_1) = (1,1)[/tex]
[tex](x_2,y_2) = (2,-1)[/tex]
The slope (m) is calculated using:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
So, we have:
[tex]m = \frac{-1-1}{2-1}[/tex]
[tex]m = \frac{-2}{1}[/tex]
[tex]m = -2[/tex]
The intercept (b) is the point where the line crosses the y-axis.
From the attached plot, the graph crosses the y-axis at [tex]y = 3[/tex]
This means that:
[tex]b = 3[/tex]
So, the equation [tex]y = mx + b[/tex] is:
[tex]y = -2x + 3[/tex]
The value of y when [tex]x = -3.5[/tex] is:
[tex]y = -2\times -3.5 + 3[/tex]
[tex]y = 7 + 3[/tex]
[tex]y = 10[/tex]
Hence:
The slope (m) is -2The intercept (b) is 3The value of y when [tex]x = -3.5[/tex] is 10Read more about linear functions at:

A cereal box says that now it contains 30 ounces of cereal. Originally, it came with 18.5 ounces of cereal Calculate the percent change and round to the
nearest percent
62% increase
38% increase
62% increase
38% decrease
Answer:62% increase
Step-by-step explanation:
old price of cereal box = 18.5 ounces
New price of cereal box =30 ounces
Percent change = (New Price - old price / Old price ) x 100
30 - 18.5 / 18.5 x 100
11.5/18.5 x100
0.621 x100
= 62% increase

Atiya rolls a 7.0 kg bowling ball down the
alley for the championship. One pin is still
standing, and Atiya hits it head-on with a
velocity of 9.0 m/s. The 2.0 kg pin moved
forward with a velocity of 14.0 m/s. What is
the new velocity of the bowling ball?
Answer:
5 m/s
Step-by-step explanation:
According to law of conservation of momentum :
m1u1 + m2u2 = m1v1 + m2v1
m1 = 7kg ; u1 = 9m/s ; m2 = 2kg ; u2 = 0 ; v2 = 14 m/s
m = masses ; u = initial velocities ; v = final velocities
m1u1 + m2u2 = m1v1 + m2v1
7*9 + 2*0 = 7*v + 2*14
63 + 0 = 7v1 + 28
63 = 7v1 + 28
63 - 28 = 7v1
35 = 7v1
v1 = 35 / 7
v1 = 5 m/s
In 1839, Georgia produced 326,000 bales of cotton . By 1860, the state produced 700,000 bales. What was the approximate percent of increase in the bales produced during that 21-year period?
Answer: 115% increase
Step-by-step explanation: To solve, we need to subtract the first value fro the second value. The formula is Percent Change = ((Second Value – First Value) ÷ First Value) x 100%
700,000-326,000=374,000. Then, divide the difference by the first value.
374,000÷326,000=1.1472392638≈1.15
1.15×100%=115%
Thus, the approximate percent of increase in the bales produced during that 21-year period is 115% increase

on selling a fan for rupees 4700 A shopkeeper loses 6% at what price must he sell it to gain 6 percentage
Given:
Selling price of a fan = Rs.4700
Loss percent = 6%
To find:
The price at which he must sell it to gain 6 percentage.
Solution:
Let x be the cost price of the fan.
Loss percent = 6%
Selling price = Cost price - 6% of cost price
[tex]S.P.=x-\dfrac{6}{100}x[/tex]
[tex]S.P.=x-0.06x[/tex]
[tex]S.P.=0.94x[/tex]
Selling price of a fan = Rs.4700
[tex]4700=0.94x[/tex]
[tex]\dfrac{4700}{0.94}=x[/tex]
[tex]5000=x[/tex]
So, the cost price of the fan is Rs.5000.
Now, he need to sell this fan in 6% gain.
Selling price = Cost price + 6% of cost price
[tex]S.P.=5000+\dfrac{6}{100}\times 5000[/tex]
[tex]S.P.=5000+300[/tex]
[tex]S.P.=5300[/tex]
Therefore, he must sell it for Rs.5300 to gain 6 percentage.

The head circumference C of a child is related to the height H of the child (both in inches) through the function H (C) = 2.15C - 10.53.
Find the inverse function, and use the inverse function to predict the head circumference of a child who is 26 inches tall. (1 point)
Answer:
The inverse function is C (H) = H+10.53/2.15. The approximate head circumference of a child who is 26 inches tall is 16.99 inches.
Step-by-step explanation:
Using the inverse function, the head circumference of a child who is 26 inches tall is;
16.99 inches
We are given the function;
H(C) = 2.15C - 10.53
Where;
H s height of the child
C is head circumference of a child the
To get the inverse of the function, we will make C the subject to get;C(H) = (H + 10.53)/2.15
At H = 26 inches, we have;
C(26) = (26 + 10.53)/2.15
C(26) = 16.99 inches

Answer: The correct option is the second one, counting from the top.
Step-by-step explanation:
For a rectangle of length L, and width W, the area can be calculated as:
A = L*W
In this case, we know that:
[tex]L = \sqrt{x}[/tex]
and
[tex]W = \sqrt[3]{x^2}[/tex]
First, we need to remember the relations;
[tex]\sqrt[n]{x^m} = x^{m/n}[/tex]
[tex]x^m*x^n = x^{m + n}[/tex]
[tex]\frac{x^n}{x^m} = x^{n - m}[/tex]
a) Now we can calculate the area of the rectangle as:
[tex]A = L*W = \sqrt{x} *\sqrt[3]{x^2} = (x^{1/2})*(x^{2/3}) = x^{1/2 + 2/3} = x^{3/6 + 4/6} = x^{1/6 + 1}[/tex]
And we can write that last part as:
[tex]x^{1/6 + 1} = x*x^{1/6} = x*\sqrt[6]{x}[/tex]
b) Now we want to find the ratio between the width and the length:
[tex]\frac{W}{L} = \frac{\sqrt[3]{x^2} }{\sqrt{x} } = \frac{x^{2/3}}{x^{1/2}} = x^{2/3 - 1/2} = x^{4/6 - 3/6} = x^{1/6} = \sqrt[6]{x}[/tex]
Now, if x = 1, the ratio will be equal to 1.
if x > 1, the ratio will be larger than 1.
if 0 < x < 1, the ratio will be smaller than 1.
