Answer: 1/10
Step-by-step explanation:
Kyle had 1/2 of a sheet cake.
He then cut this half that he had into 5 pieces of the same size.
The fraction of the sheet cake he has therefore is:
= 1/2 ÷ 5
= 1/2 * 1/5
= 1/10
Each piece was 1/10 of the sheet cake.
What is the result of multiplying the second equation by 2 and adding to the first equation?
x+3y=10
2x−y=−1
-------------
A. 5x+3y=6
B. 5x+y=8
C. 3x+2y=9
D. 3x−5y=−12
Answer:
5x + y = 8
Step-by-step explanation:
Given the equations:
x+3y=10 ____ (1)
2x−y=−1 ____ (2)
Multiply (2) by 2
2(2x - y = - 1) = 4x - 2y = - 2
4x - 2y = - 2 - - - (3)
Add (1) and (3)
4x - 2y = - 2
x + 3y = 10

Line M is represented by the equation -2/3+8. Line W is perpendicular and passes through the point (4,3)
Answer:
y= -3/2x+9
Step-by-step explanation:
Well we have to know that to find a line perpendicular to a given line, you have to have opposite slopes. So that makes the equation begin as y=-3/2x because it's opposite of y=2/3x. Then we have to make sure it goes through the point (4,3). To do that, I tweaked the numbers in my graphing calculator and it worked with 9! So the equation is y= -3/2x+9

Solve the equation x^2-6x-1=0 to the nearest tenth.
9514 1404 393
Answer:
x = {-0.2, 6.2}
Step-by-step explanation:
The values that go into the quadratic formula are a = 1, b = -6, c = -1.
[tex]x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}=\dfrac{-(-6)\pm\sqrt{(-6)^2-4(1)(-1)}}{2(1)}\\\\=\dfrac{6\pm\sqrt{40}}{2}=3\pm\sqrt{10}\\\\\boxed{x\in\{-0.2,\ 6.2\}}[/tex]

Determine the length of x in the triangle. Give your answer to two decimal places. You may use the Desmos scientific calculator:
Answer:
35.09
Step-by-step explanation:
From the question given above, the following data were:
Opposite = 12
Hypothenus = X
Angle θ = 20 °
The value of x can be obtained by using sine ratio as illustrated below:
Sine θ = Opposite / Hypothenus
Sine 20 = 12 / X
0.342 = 12 / X
Cross multiply
0.342 × X = 12
Divide both side by 0.342
X = 12 / 0.342
X = 35.09
Thus, the value of X is 35.09

The point (4, 12) is an ordered pair in a proportional relationship. What equation represents this relationship?
1. y = 3x
2.y = 12x
3.y = 4x
4.y = 48x
Answer:
1
[tex]from \: the \: question \\ y =k x - - - (i)\\ where \: k \: is \: the \: constant \: of \: proportionality \\ for \: the \: point \: given \\ y = 12 \: and \: x = 4 \\ from \: (i) \\ 12 = (k \times 4) \\ k = \frac{12}{4} \\ k = 3 \\ substitute \: for \: k \: in \: (i) \\ y = 3x[/tex]
After 8 weeks on a fitness program, mrs.Honaker can job 30 miles. Her average mileage gain has been 2 miles per week. Write an equation in slope intercept form to model this scenario.
Answer:
y = 2x + 14
Step-by-step explanation:
Equation in slope intercept form:
y = mx + c
From the scenario above ;
y = total miles = 30
Average mile gain per week = slope (m) = 2
Number of weeks (x) = 8
We can obtain intercept, c :
30 = 2(8) + c
30 = 16 + c
30 - 16 = c
14 = c
Hence,
Equation goes thus ;
y = 2x + 14

Find the area of the shape below:
Answer:
Area of shape = 120 m²
Step-by-step explanation:
Given:
Height of triangle joint = 4 m
Base = 12 m
Width = 8 m
Find:
Area of shape
Computation:
Area of shape = Area of triangle + Area of rectangle
Area of shape = (1/2)(Base x height) + [Base x Width]
Area of shape = (1/2)(12 x 4) + [12 x 8]
Area of shape = 24 + 96
Area of shape = 120 m²
find the length of each bolded arc. Round to the nearest hundredth.
Answer:
Length of the bold arc = 72.63 ft
Step-by-step explanation:
Length of the arc = [tex]\frac{\theta}{360}(2\pi r)[/tex]
Here, θ = angle subtended by the arc at the center
r = Radius of the circle
Since, angle subtended by the bold arc at the center = 360 - 73
= 287°
And radius of the circle 'r' = 14.5 ft
By substituting these values in the formula,
Length of the bold arc = [tex]\frac{287}{360}\times (2\pi)(14.5)[/tex]
= 72.632
≈ 72.63 ft
Therefore, length of the bold arc = 72.63 ft
