Answer:
50 dollars per month
Step-by-step explanation:
Given
[tex]Months = 2[/tex]
[tex]Total = 170[/tex]
[tex]Initial = 70[/tex]
Required
Determine the rate of savings
Suppose in a month, she saves x amount.
In 2 months, she would save 2x
When 2x is added to the initial savings, it gives the total amount saved.
So, we have:
[tex]2x + 70 = 170[/tex]
Collect Like Terms
[tex]2x = 170 - 70[/tex]
[tex]2x = 100[/tex]
Divide both sides by 2
[tex]x = \frac{100}{2}[/tex]
[tex]x = 50[/tex]
Hence, she saves $50 dollars monthly

the formula of ONE INTERIOR ANGLE of a REGULAR polygon.
Answer:
180° - (360/n)°, where n is the number of sides of the polygon.
Step-by-step explanation:
Polygon has n sides.
Divide the polygon radially into n congruent, isosceles triangles.
For each triangle:
vertex angle = (360/n)°
sum of base angles = 180° - vertex angle = 180° - (360/n)°
Each interior angle of the n-gon = 180° - (360/n)°

About how many years will it take for $8500 to reach $12,000 at a simple interest rate of 3.5%
Answer:12
Step-by-step explanation:
8500 x 35% = 297.50 in simple interest per year
12000 - 8500 = 3500 in interest earned in total
3500/297.5 = 11.76 number of years to make total interest from amount per year.
If you round up, almost 12 years .

Bargain Busters shop sells the cheapest soup
Step-by-step explanation:
Bargain Busters sell 4 cans of soup for £3.76
Bargain Busters sell 1 cans of soup for
3.76÷4
=0.94
cost cutters sell 3 cans of soup for £2.85
cost cutters sell 1 cans of soup for 2.85÷3
=0.95
so
Bargain Busters<cost cutters
0.94<0.95
therefore
Bargain Busters shop sells the cheapest soup

simplify the following expression. (9x^2-2x+7)+(4x^2+7x+2)
Given the function f(x) = 0.5 |x– 4| – 3, for what values of x is f(x) =7
O x = -24, x = 16
O x= -16, x = 24
O x= -1, x = 9
O x= 1, x= -9
Answer:
-16,24 B
Step-by-step explanation:
To solve this simplify the equation until it's just the absolute value brackets
7=.5 |x-4|-3
Add 3 to both sides and divide by .5 to get
20=|x-4|
Then solve this equation where the leftmost side is a positive and then a negative
So 20=x-4
x=24
24 is one of our answers
Then solve it when the left side is a negative
-20=x-4
x=-16 which is the other answer

A DVD player is regularly priced at 79.95 and is on sale for 30% off. What is the discount?
Answer:
$2.40 or $77.55
Step-by-step explanation:
I don't know if you are asking for how much off or what, so I'm doing both
First, we have to find how much we have to take off or what is 30% of 79.95 so our equation is:
79.95 x 0.03 = 2.40
So 30% of 79.95 is $2.40
To find how much our new price sale is, we have to take that $2.40 off so our equation is:
79.95 - 2.4 = 77.55
So our discount price is $77.55
hope this helps:)

Can anyone please help me figure this problem out?
Answer:
x = 12
Step-by-step explanation:
Step(i):-
From graph,
The angle of the triangle ∝ = 45°
Given hypotenuse of the triangle
AC = 12√2 and AB = x
Step(ii):-
we will choose sine function
[tex]sin\alpha = \frac{opposite side}{hypotenuse}[/tex]
[tex]sin\alpha = \frac{x}{12\sqrt{2} }[/tex]
Given that an angle ∝ = 45°
[tex]sin45 = \frac{x}{12\sqrt{2} }[/tex]
[tex]\frac{1}{\sqrt{2} } = \frac{x}{12\sqrt{2} }[/tex]
[tex]\frac{1}{1 } = \frac{x}{12}[/tex]
x = 12
Final answer:-
x = 12
Jack and Jill both start at point A. They each walk in a straight line at an angle of 105° to each other. After 45 minutes Jack has walked 4.5km and Jill has walked 6km. How far apart are they? Round to the nearest hundredth.
Answer: The distance between them is 8.38 km
Step-by-step explanation:
Let's suppose both of them start at the point (0km, 0km), and that Jack walks along the positive x-axis, then Jill walks at an angle of 105° measured from the positive x-axis.
After 45 minutes, jack has walked 4.5km, then if his initial position was (0 km, 0 km)
Then his new position will be (4.5km, 0km)
Jill has walked 6km, but we need to write this in rectangular components.
We can think in this as a triangle rectangle, then the components will be:
x-component = 6 km*cos(105°) = -1.55 km
y-component = 6km*sin(105°) = 5.80 km
Then the new position of Jill is ( -1.55km, 5.80km)
Now, we know that the distance between two points (a, b) and (c, d) is:
Distance = √( (a - c)^2 + (b - d)^2)
Then the distance between Jill and Jack will be equal to the distance between ( -1.55km, 5.80km) and (4.5km, 0km)
This is:
Distance = √( (-1.55km - 4.5km)^2 + (5.80km - 0km)^2)
Distance = 8.38 km
This means that they are 8.38km apart.
Specify the set of B by giving a written description of It’s element where B={ 0,1,4,9,16,25}
Answer:
B = { square numbers less than 30 }.
or
B = {x/x is square of a whole number; [tex]0 \leq x \leq 5[/tex] }
Step-by-step explanation:
Given the set B
B={ 0,1,4,9,16,25}
Let us check the elements in set B.
[tex]x = 0 = 0^{2}[/tex]
[tex]x\:=\:1\:=\:1^2[/tex]
[tex]x\:=\:4\:=\:2^2[/tex]
[tex]x\:=\:9\:=\:3^2[/tex]
[tex]x\:=\:16\:=\:4^2[/tex]
[tex]x\:=\:25\:=\:5^2[/tex]
It is clear that each element in set B is a square of a whole number.
Thus, we can specify set of B by giving a written description of Its element in a variety of ways, such as:
B = { square numbers less than 30 }.
or
B = {x/x is square of a whole number; [tex]0 \leq x \leq 5[/tex] }
Consider the expression 40+24 Find the greatest common factor of the two numbers and rewrite the expression using the distributive property
Answer:
Greatest Common Factor of 40+24 is 8
Rewriting the expression using the distributive property we get 8(5+3) =8(5)+8(3)
Step-by-step explanation:
We need to F=find the greatest common factor of the two numbers 40+24 and rewrite the expression using the distributive property
Greatest Common Factor:The greatest number that is divisible by both numbers is known as greatest common factor.
So, Greatest Common Factor of 40+24 is 8
Now, Taking 8 common we get: 8(5+3)
Distributive property:It is written as: a(b+c) = ab+ac
So, we have 8(5+3) =8(5)+8(3)
Rewriting the expression using the distributive property we get 8(5+3) =8(5)+8(3)
