Lilo has 1,000 minutes per month on her cell phone plan. Write and solve an inequality showing the maximum number of minutes that Lilo can use it not be charge extra on her cell phone plan when she only used 615 minutes.
Answer:
Lilo has a maximum of 385 minutes to use on her cell phone.
A ≤ 385
Step-by-step explanation:
Let letter A represent the additional number of minutes that Lilo can talk
A + 615 ≤ 1,000
subtract 615 from both sides
A + 615 - 615 ≤ 1,000 - 615
A + 0 ≤ 385
A ≤ 385
Lilo has a maximum of 385 minutes to use on her cell phone.
A + 615 ≤ 1,000; A ≤ 385

Find the perimeter of the shaded region. Round your answer to the nearest hundredth.
Answer:
59.16 units
Step-by-step explanation:
Given that,
The length of rectangle, L = 13
The breadth of the rectangle, B = 6
The perimeter of the shaded region = perimeter of rectangle - 2(perimeter of semicircle)
[tex]P=13\times 6-[2\times \dfrac{2\pi r}{2}]\\\\=78-2\pi r\\\\=78-2\times 3.14\times 3\\\\=59.16[/tex]
So, the perimeter of the shaded region is 59.16 units.

Mary has a budget for groceries fuel, and utilities. She spent 30% of her budget in groceries if mary spent 42$ on groceries than how much is her budget
Given:
Mary spent 30% of her budget in groceries.
She spent 42$ on groceries.
To find:
The total amount of her budget.
Solution:
Let x be the total amount of the budget.
Then, the amount spent on groceries is 30% of x.
[tex]\dfrac{30}{100}x=0.3x[/tex]
She spent 42$ on groceries.
[tex]0.3x=42[/tex]
Divide both sides by 0.3.
[tex]x=\dfrac{42}{0.3}[/tex]
[tex]x=140[/tex]
Therefore, the total amount of the budget is 140$.

Anna makes a quilt by sewing together green, white, and yellow fabric. When she finishes, 2/6 of the quilt is green, and 3/6 is yellow. The rest is white. What fraction of the quilt is white? Show your work.
Answer:fraction of the quilt is white = 1/6
Step-by-step explanation:
Let the total quilt be = 1 ( since we are dealing with fraction)
The portion of quilt that is green 2/6
The portion of quilt that is yellow 3/6
The portion that is white = Total quilt −( portion of quilt that is green and yellow)
=1−( 2/6 + 3/6 )
=1 −5/6
=1/6

The equation has three solutions:

Step-by-step explanation:
||[tex]4^{x} - 3[/tex]|[tex]-2[/tex]| = 1
|[tex]4^{x} - 3[/tex]|[tex]-2[/tex] = 1 |[tex]4^{x} - 3[/tex]|[tex]-2[/tex] = - 1
|[tex]4^{x} - 3[/tex]| = 1+2 |[tex]4^{x} - 3[/tex]| = -1+2
|[tex]4^{x} - 3[/tex]|=3 |[tex]4^{x} - 3[/tex]| = 1
[tex]4^{x} - 3[/tex] =3 [tex]4^{x} - 3[/tex] = - 3 [tex]4^{x} - 3[/tex] = 1 [tex]4^{x} - 3[/tex] = - 1
