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!

Answers

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

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.

Answers

Ok 12cm 40• is 50 minutes

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

Answer:

y = 27/6

Step-by-step explanation:

3/2x - 6 = -9/2x + 21

12/2x = 27

6x = 27

Since both are y, you know the values are equal to each other.
3/2x - 6 = -9/2x + 21
3/2x = -9/2x + 27
Get rid of fraction (multiply by 2)
3x = -9x + 54
12x = 54, x = 4.5
Plug 4.5 into any equation as x
y = 3/2(4.5) - 6
y = 6.75 - 6 = 0.75

Solution: y = 0.75 or 3/4

21 less than four times a

six times the number plus
11. What is the number?

Answers

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
