Use the following situation for questions #1-10.
Ashley has two jobs: mowing lawns and babysitting. She earns $10 per hour mowing lawns
(x) and $8 per hour babysitting (y). She wants to earn at least $160 per week.
4. What is the x-intercept for the inequality? Show your work!
Answer:
We have the variables:
x = hours that she mows lawns per week.
y = hours that she babysits per week.
She earns $10 per hour mowing lawns and $8 per hour babysitting.
Then she earns a total of:
x*$10 + y*$8
We also know that she wants to earn at least $160 per week.
Then we have the inequality:
Total weekly earnings ≥ $160
This can be written as:
x*$10 + y*$8 ≥ $160
Now we want to find the x-intercept of the inequality.
The x-intercept is the possible y-values when x = 0 (the x-axis)
Then we just need to set x = 0 and find the possible solutions for y.
0*$10 + y*$8 ≥ $160
y ≥ $160/$8 = 20
y ≥ 20
The x-intercept of the inequality is the set of all the points (0, y) such that:
y ≥ 20
Find the area of the shaded region
Answer: 40
Step-by-step explanation:
Answer:
[tex]16\pi - 24\sqrt{3}[/tex]
Step-by-step explanation:
The shaded area is the area of the circle minus the area of the hexagon. (It's like a circle with a hexagon cut out of it.)
Area of the circle is [tex]A_\text{circle} =\pi r^2 = \pi\cdot 4^2 = 16\pi[/tex]
Area of the hexagon. The attached image shows two radii drawn that create an equilateral triangle with three 60 degree angles. The blue altitude (marked h) splits that triangle into two 30-60-90 triangles. The bottom side is split into two 2-unit segments. The altitude h is the short leg of the 30-60-90 triangle multiplied by [tex]\sqrt{3}[/tex].
So, the area of one equilateral triangle is [tex]\frac{1}{2}(\text{base})(\text{height})=\frac{1}{2}\cdot 4\cdot 2\sqrt{3}=4\sqrt{3}[/tex].
The hexagon is made up of 6 such equilateral triangles, so its area is [tex]A_\text{hexagon}=6\cdot 4\sqrt{3}=24\sqrt{3}[/tex]
Finally, the shaded region has area (circle minus hexagon):
[tex]16\pi - 24\sqrt{3}[/tex]

The diameter of an official squash ball ranges from 39.5 mm to 40.5 mm. What is the difference in volume between the larger and smaller official squash ball?
Answer:
2513.41 mm³
Step-by-step explanation:
Given that,
The diameter of ball 1 = 39.5 mm
Radius of ball 1 = 19.75 mm
The volume of ball 1 is :
[tex]V_1=\dfrac{4}{3}\pi r^3\\\\=\dfrac{4}{3}\pi \times 19.75^3\\\\=32269.32\ mm^3[/tex]
The diameter of ball 2, = 40.5 mm
Radius = 20.25 mm
Volume of ball 2,
[tex]V_2=\dfrac{4}{3}\pi \times 20.25^3\\\\=34782.73\ mm^3[/tex]
Difference in volume = V₂ - V₁
= 34782.73 - 32269.32
= 2513.41 mm³
So, the difference in volume of the ball is equal to 2513.41 mm³.

If we spin the spinner 10 times, what is the best prediction possible for the number of times it will land on yellow or purple? 3 blue,5 yellow, 2 red.
Answer:
Yellow = 5 times and I think you meant blue since there is no purple so blue = 3 times
Step-by-step explanation:
There is ten in all and half of the spaces are yellow, or 50%. Out of ten times, you should land on it about half, or 5. For blue, there are 3 spaces, or 30%. Out of ten times, you should lamd on it about three.

21 less than four times a
number is the same as
six times the number plus
11. What is the number?
Answer:
-16 =n
Step-by-step explanation:
Let n= number
4n -21 = 6n +11
Subtract 4n from each side
4n-4n -21 = 6n-4n +11
-21 = 2n+11
Subtract 11 from each side
-21-11 = 2n
-32 = 2n
Divide by 2
-32/2 = 2n/2
-16 =n
Answer : -16 =n
Step-by-step explanation:
Let n= number
4n -21 = 6n +11
Subtract 4n from each side
4n-4n -21 = 6n-4n +11
-21 = 2n+11
Subtract 11 from each side
-21-11 = 2n
-32 = 2n
Divide by 2
-32/2 = 2n/2
-16 =n

a chord 12cm long subtends an angle of 40° at the centre of the circle. calculate the radius of the circle.
please answer with explanation its so urgent.
The radius of the circle is 17.54 cm
What is the relation between central angle and angle on circumference?Consider an arc of a circle.
Suppose it subtends θ angle on the rest of the part of the circumference (at any point). Then it subtends 2θ angle on the center of that circle.
Given that Chord 12 cm long subtends an angle of 40 degrees at the center of a circle.
θ= 40° = 0.698 radian
Let R be the radius of circle.
Chord Length = 2Rsin(θ/2)
12=2R sin (0.698 /2)
R= 17.54
Hence Radius of circle = 17.54 cm
