If a rectangle is 30 feet long and the perimeter is 78 feet. What would be the width of the rectangle?
Answer:
The width should be 9 feet in this situation
Step-by-step explanation:
(30 x 2) + (9 x 2) =
60 + 18 =
78 ft
Or
78 - (30 X 2) =
78 - 60 =
18 / 2 =
9

find the value of x. round to the nearest tenth
Answer:
using Pythagoras theorem x=32.7
Answer:
21.7
Step-by-step explanation:
In order to solve this problem, we can use trig functions. We are given the side adjacent to the 37° given and we are looking for the hypotenuse. This means that cosine function is the most suitable. Cosine is written as:
cos(θ°) = adjacent / hypotenuse
We can substitute the values we have:
cos(37°) = 17.3 / x
And rewrite the expression:
x = 17.3 / cos(37°)
Then, use a calculator to evaluate:
x = 21.66194689
This can be rounded to 21.7
Find the distance between the two points rounding to the nearest tenth (if necessary).

Solve for x please help !!!!!!!
Answer:
x ≈ 20.31
Step-by-step explanation:
By applying tangent rule in the given right triangle,
tan(55°) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
Measure of the opposite side = 29 units
Measure of the adjacent side = x
Substitute these values in the expression,
tan(55) = [tex]\frac{29}{x}[/tex]
x = [tex]\frac{29}{tan(55)}[/tex]
x = 20.306
x ≈ 20.31
A pair of equations is shown below: y = 2x − 1 y = 4x − 5 Part A: In your own words, explain how you can solve the pair of equations graphically. Write the slope and y-intercept for each equation that you will plot on the graph to solve the equations. (6 points) Part B: What is the solution to the pair of equations? (4 points)
WORTH 100 POINTS
Answer:
Solution given:
x=2
y=3
The requried solution to the pair of equations is (2, 3).
What are simultaneous linear equations?Simultaneous linear equations are two- or three-variable linear equations that can be solved together to arrive at a common solution.
Here,
Part A: To solve the pair of equations graphically, we need to plot both equations on the same coordinate plane. To plot each equation, we can use the slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept.
For the equation y = 2x - 1, the slope is 2 and the y-intercept is -1. For the equation y = 4x - 5, the slope is 4 and the y-intercept is -5. We can plot these two lines on the same coordinate plane and find their intersection point.
Part B: We can find this point by setting the two equations equal to each other and solving for x:
2x - 1 = 4x - 5
Subtracting 2x from both sides, we get:
-1 = 2x - 5
Adding 5 to both sides, we get:
4 = 2x
Dividing by 2, we get:
x = 2
Now that we have found the value of x, we can substitute it into either equation to find the value of y. Using the equation y = 2x - 1, we get:
y = 2(2) - 1
y = 3
Therefore, the solution to the pair of equations is (2, 3).

Pply the converse of the pythagorean theorem to determine if it's a right triangle. Is the triangle a right triangle? No, 92+402=412. No, 9 squared + 40 squared not-equals 41 squared Yes, 92+402=412. Yes, 9 squared + 40 squared not-equals 41 squared
Answer:
Yes, 9^2+40^2=41^2
Step-by-step explanation:
From the Pythagoras’ theorem, the square of the hypotenuse of a right triangle equals the sum of the squares of the two other sides
From what we have , the side lengths are 9, 40 and 41
As we can see, 41 is the longest side length and that makes it the hypotenuse
The square of the two other sides is 40^2 + 9^2 = 1,681
Also, 41^2 = 1,681
As we can see, the sum of the squares equal the square of the hypotenuse
Since this follows the theorem, we can conclude that the triangle is a right triangle
Answer:
C, Yes, 92+402=412.

Answer:
Interval $11 - $15 = 0.2
Step-by-step explanation:
Sum of frequency, Σf = (8+6+4+2+4+6+2) = 32
Relative frequency = f / Σf
Interval :
1 - 5 = 8 / 20 = 0.4
6 - 10 = 6 / 20 = 0.3
11 - 15 = 4 / 20 = 0.2
16 - 20 = 2 / 20 = 0.1
21 - 25 = 4 / 20 = 0.2
26 - 30 = 6 / 20 = 0.3
31 - 35 = 2 / 20 = 0.1

2x-=8+x
Collect like terms
2x-x=8
x=8
Hence the hourly rate is $8

Answer:
y is 107° and z is 36°
Step-by-step explanation:
73° and y are supplementary angles so they add up to 180°
Answer:
y = 107
z = 36
Step-by-step explanation:
We are given that line o is parallel to line m, and we can notice line k is a transversal through them both. Using same side interior angles, we can say that:
y + 73 = 180
and
y = 107
Next, using vertical angles, we can say that:
5z - 73 = y
We already have y = 107, so we can substitute that in:
5z - 73 = 107
5z = 180
z = 36

Mark makes $60 for every six hour shift he works. How much will he make if he works an eight hour shift
Answer:
Mark will make $80 if he works an eight-hour shift.
Step-by-step explanation:
For every six hour shift he works, Mark makes $60
This implies that for every hour, he makes $10 ($60/6)
Therefore, for working an eight-hour shift, Mark will make $80 ($10 * 8) or ($60/6 * 8).
We can conclude that Mark's employer pays him $10 per hour.
This hourly rate can be used to work out how much Mark will earn if he works for a month or a year, as the case may be.
