Step-by-step explanation:
Step one:
given data
we are told that she wants her balance to be at least $100
y=100-------1
the expression relating her current balance and spending rate is
let y be the total and m be the number of months
y=330-11m----------2
Required
the number of months m
equating 1 and 2 we have
100=330-11m
11m=330-100
11m=230
m=230/11
m=20.9
m=21 approx
This means that she will keep her account open for 1 year 9 months
hi can u help me with my math homework
where is it? but sure
Can someone please help me with this?
Proportional equations are the equations that have the graph which pass through (0,0).
y = -9x is proportional.
y=x is proportional
y=1/2x is proportional
That's it. Only these three equations have (0,0) intercept.

The diagram shows a convex polygon.
Find the value of a.
Answer:
The value of a is 15.
Step-by-step explanation:
First, you have to find the total interior angles of the polygon using the formula, sum = (n-2)×180°, where n represents the number of sides :
sum = (n-2)×180°
sum = (5-2)×180°
sum = 540°
Given that the sum of the interior angle is 540° so in order to find the value of a, you have to add up all the angles in terms of a :
3a + 150 + 8a + 6a + 9a = 540
26a + 150 = 540
26a = 390
a = 390 ÷ 26
a = 15
Matt can walk 500 m from his home on King Street, and then 900m along Queen Street to go to his school. He can also walk across a diagonally across a park from his home to his school. Assuming King Street and Queen Street meet at right angles, how far does he walk across the park to go to school?
Answer:
He walks 1030 meters if he walks across the park.
Step-by-step explanation:
In order to solve this question we will need to know that [tex]c^{2} = a^{2} + b^{2}[/tex] (were c is the length of the hypotenuse (the diagonal line) of a right angle triangle, and a and b are the legs (the sides that form a right angle). So them means that.....
Let "c" be the distance he will need to walk if he was going to go through the park
Let "a" be the distance he walks on King Street
Let "b " be the distance he walks on Queen Street, then.....
[tex]c^{2} = a^{2} + b^{2}[/tex]
[tex]c = \sqrt{a^{2} + b^{2} }[/tex]
(Now plug in the values of a and b and get.....)
c = [tex]\sqrt{500^{2} + 900^{2} }[/tex]
c = [tex]\sqrt{1060000 }[/tex]
c = 1029.563014............
So I would assume that you have to round to the nearest meter. And as a result we get 1030 meter.

Answer:
x = 4
Step-by-step explanation:
5x + 2 and 4x + 6 are alternate angles and are congruent, thus
5x + 2 = 4x + 6 ( subtract 4x from both sides )
x + 2 = 6 ( subtract 2 from both sides )
x = 4

The angle e lies in Quadrant II.
sin 0 = 3/4
What is cos O?
Answer:
-√7/4
Step-by-step explanation:
Mathematically;
Sine is the ratio of opposite to hypotenuse
So here, hypotenuse is 4
The opposite is 3
To get the adjacent, we use the Pythagoras’ theorem which states that the square of the hypotenuse is equal the sum of the squares of the two other sides
Let the adjacent be x
4^2 = 3^2 + x^2
x^2 = 16-9
x^2 = 7
x = √7
The cosine is the ratio of the adjacent to the hypotenuse
Since we want to consider quadrant II
Cosine is negative here;
So the answer for Cos will be;
Cos theta = -√7/4

Write 1.2 as a fraction or mixed number.
Answer: 1 1/5
Step-by-step explanation:
Answer:
Mixed number- 1 and 1/5
Fraction- 12/10
Step-by-step explanation:
1.2 is read as 1 and 2 tenths. 1 and 2 tenths is the same as 1 and 2/10.
1 and 2/10 in simplest from is 1 and 1/5.
1 and 1/5 can also be written as 12/10.

4x + 5y = 7 and 8x + 5y = 9 *
Elimination
Answer:
Solve equation [2] for the variable y
[2] y = 8x + 7
// Plug this in for variable y in equation [1]
[1] 4x - 5•(8x+7) = -9
[1] -36x = 26
// Solve equation [1] for the variable x
[1] 36x = - 26
[1] x = - 13/18
// By now we know this much :
x = -13/18
y = 8x+7
// Use the x value to solve for y
y = 8(-13/18)+7 = 11/9
Solution :
{x,y} = {-13/18,11/9}

Use the following system of equations to select the appropriate response.
Step 1 of the substitution Method to solve system of equations. use the second equation and solve for the x Variable.
A. x = y - 3
B. x = -y + 3
C. x = -y - 3
D. x = y + 3
Answer:
Step-by-step explanation:
Given system of equations is,
8x + 10y = 120 -----(1)
x - y = -3 ------(2)
From the second equation,
x = y - 3 [Option A]
Now we substitute the value of x in equation (1) and solve for y,
8(y - 3) + 10y = 120
8y - 24 + 10y = 120
18y = 120 - 24
y = [tex]\frac{96}{18}[/tex] = 8
From equation (2)
x - 8 = -3
x = 8 - 3
x = 5
How long is 25% of 60 minutes? Explain your answer.
How long is 75% of 60 minutes? Explain your answer.
1: 60 - 25% = 45 minutes
2: 60 - 75% = 15 minutes
Answer:
15 minutes because 25 percent goes in 4 times to 100 so 60 divided by 4 is 15
45 minutes because 75 percent goes in 3 times to 100 and 15x3 is 45
