Alex is trying to save $230 to buy a new tablet. Right now, he has $40 and can save $38 a week from
his allowance. Write and solve an inequality that can be used to find the minimum number of weeks it
will take Alex to have the money to buy the tablet. Write a sentence to interpret your solution.
Answer:
Step-by-step explanation:
So we know that Alex is trying to save $230.
He already has forty dollars so we can take forty away from two hundred and thirty. This leaves us with $190 that we need to save.
If he is saving $38 per week. We can divide or estimate and multiply. I prefer to multiply so that is the method I will use right now.
38×5= 190
Therefore, Alex will have enough money to buy a tablet in five weeks.
I hope I am correct and I explained this in a way that you can understand and do it yourself next time.

What is the area of the sector of the circle when the radius is 10 and the shaded part is 45 degrees
Answer:
We are solving for the area so; A=134.16
Step-by-step explanation:
Here is the formula for finding area of a sector:
A = [tex]\pi r^{2}[/tex] × θ° ÷ 360°
where theta is the angle of the sector you wish to find, and r is the radius of the circle.
Substitute the numbers in and you get:
[tex]\frac{25\pi }{2} unit ^{2}[/tex]
You should find 39.26991 as your answer (or any number rounded according to the value of pi)

A triangle has a perimeter of 15 feet. Side B is one foot longer than side A. Side C is two feet longer than side A. What is the length of each side.
Answer:
Side A = 4
Side B = 5
Side C = 6
Step-by-step explanation:
In the following equation, variable a is the length of Side A
a + (a + 1) + (a + 2) = 15
a + a + a + 1 + 2 = 15
3a + 3 = 15
- 3 - 3
3a (÷ 3) = 12 (÷ 3)
a = 4
Side A = 4
Side B = (a + 1) = (4 + 1) = 5
Side C = (a + 2) = (4 + 2) = 6

i need urgent help
this is my maths work
Answer:
A. only inequality 1.
Step-by-step explanation:
The inequality 1 can be written as
- 5 = 1 - 3d
- 5 - 1 = - 3d
- 3d = - 6
d = 2
Now the inequality 2 can be written as
- 1 =( 1 - d) / 3
- 3 = 1 - d
d = 1 + 3
d = 4
So the answer is A only inequality 1.
Hope it will help :)

I need help with Geometry
Answer:
1st option
Step-by-step explanation:
We see that one angle is 28, so because of alternate interior angles, angle two is also 28. Angle one is 90 because those two lines are perpendicular and the only available options for A is 90, and measurement angle 3 is going to be 180 - (90 + 28) (sum of interior angles in a triangle) and you're going to get 62.
