Answer:
≈ 66.5 m
Step-by-step explanation:
Using the sine ratio in the right triangle
sin12° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{d}{320}[/tex] ( multiply both sides by 320 )
320 × sin12° = d , then
d ≈ 66.5 m ( to 1 dec. place )

How to write algebraic expression?Algebraic expression are the expression which consist the variables, coefficients of variables and constants.
The algebraic expression are used to represent the general problem in the mathematical way to solve them.
Steps to write down the simple algebraic expression-
Identify all the factors of the expression.Assume a variable for the changing values.Put a coefficient for the variable, if there is any rate of change of variable.Use constant numbers for the fixed values.a. Give 2 input-output pairs that represent this function.
There is total 25 cent is 1 quarter. Thus, when if there are 2 quarters, then the value of cent is 50 and when there are 4 quarters, then the value of cents is 100 cents.
Hence, the two pairs should be as,
(2, 50), (4, 100)
b. Write an equation that represents this function.As, v is the value of quarters in cents. There is total 25 cent is 1 quarter. The total quarter is n. Thus, the function can be given as,
[tex]v(n)=25\times n\rm \;\;cents[/tex]
c. Find the output when the input is 10.Put the value 10 on the place of n in the above equation as,
[tex]v(10)=25\times (10)\\v(10)=250\rm cents[/tex]
The output when the input is 10 is 250 cents.
d. Identify the independent and dependent variables.The independent value is the number of quarters and the dependent variable is the value of cents.
Hence, the independent value is the number of quarters and the dependent variable is the value of cents and the equation that represents this function is,
[tex]v(n)=25\times n\rm \;\;cents[/tex]

Answer:
131°
Step-by-step explanation:
to find the total degrees of this polygon, we use the equation
=> n - 2 × 180° (n= number of sides)
5 - 2 × 180° = 540°
now by using angle sum property,
540° = 80° + 148° + 81° + 100° + [tex]x[/tex]°
540° = 409° + [tex]x[/tex]°
[tex]x[/tex]° = 540° - 409°
[tex]x[/tex]° = 131°
Joe measures side lengths of triangular canvas to be 22 inches, 10 inches and 11 inches. Could those be correct measurements?
Answer:
Incorrect measurement
Step-by-step explanation:
Given
Shape: Triangle
Length: 22in, 10in and 11in
Required: Determine if the measurements are correct
For the measurement of a triangle to be true, the sum of any 2 sides must be greater than the length of the third side.
i.e.
[tex]22 + 10 > 11[/tex] --- True
[tex]22 + 11 > 10[/tex] --- True
[tex]11 + 10 > 22[/tex] --- False
Since all three conditions are not true, then the measurements are incorrect

Kirby middle school some students or survey to see which social media app they use the most the results are shown below solver and explain how to calculate and what percent of students to snap the most
Answer: 44%
Step-by-step explanation:
First add up the number of students using each app the most to find out the total number of students surveyed:
= 8 + 22 + 20
= 50 students
To find out the percent of students using Snap, multiply the proportion of those using Snap the most out of the total number of students surveyed by 100%.
= 22/50 * 100%
= 44%
：Find x+y, if: 2x+3y=8 and 3x+5y=13
Answer:
x=1
y=3
Step-by-step explanation:
Heres a photo with explanation
The solution of the equations 2x + 3y = 8 and 3x + 5y = 13 will be (1, 2). Then the value of the expression x + y will be 3.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
The equations are given below.
2x + 3y = 8 ...1
3x + 5y = 13 ...2
Multiply equation 1 by 3 and equation 2 by -2, then we have
6x + 9y = 24
-6x - 10y = - 26
Add the above equations, then we have
- 26 + 24 = 9y - 10y
y = 2
Then the value of the variable 'x' is calculated as,
3x + 5(2) = 13
3x + 10 = 13
3x = 3
x = 1
Then the value of the expression x + y is calculated as,
⇒ x + y
⇒ 1 + 2
⇒ 3
The solution of the equations 2x + 3y = 8 and 3x + 5y = 13 will be (1, 2). Then the value of the expression x + y will be 3.

2. 3x = у у= 2х + 2 2
Answer:
Step-by-step explanation:
3x = y ------------(I)
y = 2x + 22 ---------------(II)
Substitute y = 2x + 22 in equation (I)
3x = 2x + 22 {Subtract 2x form both sides}
3x -2x = 22
x = 22
Plugin x = 22 in equation (I)
3*22 = y
y = 66
Answer:
Step-by-step explanation:
3x = y
y = 2x + 22
3x = 2x + 22
3x -2x = 22
x = 22
3x22 = y
66=y

find 2 sets of numbers
Answer:
3,3,4,6,6
4,4,5,6,7
5,5,6,6,8
Step-by-step explanation:
mode = n
median= n+1
mean = n+2
Range = n+3
let sets:
a,b,c,d,e
mode = n, at least two of them are the same and equal to n
n,n,c,d,e
median belong to the set, in ascending order:
n,n,n+1,d,e
which means d,e ≥ n+1, d≠e
mean is n+2
5(n+2)=n+n+n+1+d+e
2n+9=d+e
Assume e is the maximum:
Range is n+3:
e-n=n+3
e=2n+3

The vertices of a triangle are A (4,-2), B(4,-4), C(12, -4). If the triangle is dilated by a scale factor of 1/4 what will be the coordinates of C'?
Answer:
(3, -1)
Step-by-step explanation:
12×1/4=3
-4×1/4=-1
The coordinates of C' after dilation with a scale factor of 1/4 are (7, -3).
To find the coordinates of C' after dilation, we need to apply the scale factor to the original coordinates of C (12, -4). Since the triangle is dilated with respect to the origin, we can calculate the new coordinates by simply multiplying the original coordinates by the scale factor, which is 1/4.
C' coordinates: (12 * 1/4, -4 * 1/4) = (3, -1)
However, since the triangle is not dilated with respect to the origin, we need to adjust the coordinates according to the translation of the dilation center. In this case, the dilation center is at vertex A (4, -2).
Translation vector: (4 - 0, -2 - 0) = (4, -2)
Final coordinates of C': (3 + 4, -1 - 2) = (7, -3)
So, the coordinates of C' after the dilation are (7, -3).
