Solve for x, Solve for z, and Solve for y
Answers
Answer:
x=38 degrees, y=41 degrees, z=97 degrees
Step-by-step explanation:
The Triangle Angle-Sum Theorem states that all interior angles of a triangle will add up to 180 degrees.
Look at the triangle to the right. The missing value of x will complete the theorem, therefore the equation 59+83+x=180 will find x. x=38 when we solve the equation.
The triangle on the left has two missing variables, but since angles z and 83 degrees are supplementary to each other, we can make another equation z+83=180 since supplementary angles add up to 180 degrees. z=97 when we solve the equation.
Since we have z, we can now find the value of y given the Triangle Angle-Sum Theorem. The equation would be 42+97+y=180 so we can solve for y. y=41 when we solve the equation.
Answer:
x=38
z=97
y=41

Find the area of a sector with a central angle of 140° and a diameter of 9.6 cm. Round to the nearest tenth.
Answers
Answer:
[tex]A=28.1\ cm^2[/tex]
Step-by-step explanation:
The area of a circular sector with a central angle θ and radius r is given by:
[tex]\displaystyle A=\frac{1}{2}r^2 \theta[/tex]
Note: The angle must be in radians.
We need to find both the radius and the angle in radians.
Diameter = 9.6 cm
Radius r=Diameter/2=4.8 cm
Angle in radians= Angle in degrees*π / 180
θ = 140*π / 180 = 2.4435 rad
Now we calculate the area:
[tex]\displaystyle A=\frac{1}{2}(4.8)^2 2.4435[/tex]
[tex]\boxed{A=28.1\ cm^2}[/tex]

Write the equation of a line in the point-slope form with a slope of 2 and passes through the point (-5,2)
Answers
Answer:
y - 2 = 2(x + 5)
Step-by-step explanation:
Use the point slope form: y - y1 = m(x - x1), where m is the slope and (x1, y1) is a point on the line.
Plug in the point and slope:
y - y1 = m(x - x1)
y - 2 = 2(x + 5) is the equation

The ratios 5:3 and 10:6 are equivalent ratio
Is the ratio 15:12 equivalent to these?? Explain your reasoning
Answers
No, the ratio of 15:12 is not equivalent to 5:3 and 10:6 because
- 15:12 = 5:4
- 5:3
- 10:6 = 5:3
Given,
5:3 and 10:6 are equivalent ratios.
We need to see whether these ratios are equivalent to 15:12.
What are proportional ratios?The ratios which are equal are called proportional ratios.
Example:
1:2 = 5:10 = 6:12 = 7:14
5/10 = 1/2
6/12 = 1/2
7/14 = 1/2
We have,
5:3 and 10:6
- 5/3
- 10/6 = 5/3
We have,
15:12
= 15/12
= 3x5/3x4
= 5/4
We see that 5:3 and 10:6 are not equivalent to 15:!2.
Thus,
No, the ratio of 15:12 is not equivalent to 5:3 and 10:6 because
- 15:12 = 5:4
- 5:3
- 10:6 = 5:3

I believe the answer is:

690,000
Process:
685,135
In the ten thousands place is the number 8. To round to the nearest ten thousand, we have to look at the place value right behind it, the thousands place.
If the number in the thousands place is greater than or equal to 5, we round 8 up to 9. If the number in the thousands place is less than 5, we leave 8 as it is.
We can see that in the thousands place is the number 5, meaning that we round up to 9.

Lisa finds a treasure chest full of 1000 jewels: 600 emeralds, 300 sapphires, and 100 rubies. She stuffs her pockets full of jewels completely at random, but they can only hold 100 jewels. What is the probability that all 100 jewels she took were sapphires?
Answers
Given:
Total number of jewels = 1000
Emeralds = 600
Sapphires = 300
Rubies = 100 rubies
100 jewels she took randomly.
To find:
The probability that all 100 jewels she took were sapphires.
Solution:
Number of selected jewels = 100
Total number of jewels = 1000
We have to select 100 out of 1000.
So, the total number of outcomes [tex]=^{1000}C_{100}[/tex]
Number of sapphires = 300
We have to select 100 out of 300 sapphires .
So, the favorable outcomes [tex]=^{300}C_{100}[/tex]
Now,
[tex]\text{Required probability}=\dfrac{\text{Favorable outcomes}}{\text{Total outcomes}}[/tex]
[tex]\text{Required probability}=\dfrac{^{300}C_{100}}{^{1000}C_{100}}[/tex]
Therefore, the required probability is [tex]\dfrac{^{300}C_{100}}{^{1000}C_{100}}[/tex].
The Doe family had a rectangular garden with a 58-foot perimeter. They reduced the length by 7 feet and decreased the width to be half as wide as it was originally. This resulted in a garden with a 34-foot perimeter. What is the area of the new smaller garden?
Answers
Answer:
60 square foot
Step-by-step explanation:
Perimeter of a rectangular garden = 58 foot
Let x and y denote length and width of the rectangular garden.
2 (Length + Width) = Perimeter of the rectangular garden
[tex]2(x+y)=58\\x+y=\frac{58}{2}\\ x+y=29[/tex]
So,
length = x
width = y = [tex]29-x[/tex]
The length is reduced by 7 feet and the width becomes half.
New length = [tex]x-7[/tex]
New width = [tex]\frac{1}{2}(29-x)[/tex]
New perimeter = 34 foot
[tex]2[(x-7)+\frac{1}{2}(29-x)]=34\\ 2[2(x-7)+(29-x)]=2(34)\\2(x-7)+(29-x)=34\\2x-14+29-x=34\\2x-x-14+29=34\\x+15=34\\x=34-15\\x=19[/tex]
So,
New length [tex]=x-7=19-7=12\,\,foot[/tex]
New width = [tex]\frac{1}{2}(29-19)=\frac{1}{2}(10)=5\,\,foot[/tex]
Area of the new smaller garden = New length × New Width
= 12 × 5
= 60 square foot
