If I spend 3/4 of the
money in my pocket and then 1/2 of what is left.
What fraction of the sum remains?
Please hurry
Answer:
1/8 of the original sum still remains.
Step-by-step explanation:
If you spend 3/4 of what you have, you have 1/4 left.
Now you spend 1/2 of that 1/4, so basically divide 1/4 by 2. When dividing fractions you can multiply the fraction by the reciprocal of the other fraction.
[tex]\frac{1}{4}[/tex] ÷ [tex]\frac{2}{1}[/tex] = [tex]\frac{1}{4}[/tex] * [tex]\frac{1}{2}[/tex]
= 1/8
So I think 1/8 of the original sum still remains.

Nishi invests £4700 at 6% interest per year. Work out how much she will have altogether after: 2 years- £ 5 years- £ 7 years- £ 10 years- £
Answer:
Step-by-step explanation:
To calculate the compound interest we want to multiply the amount of money (£4700) by the interest (6%) which would be the percentage multiplier!
To get the new amount we do:
Original amount × (percentage multiplier)ⁿ
The amount of years would be the indices.
For the first year:
£4700x1.06= £4982.
But we want to find out how much she will have altogether in different years.
So for two years:
£4700x1.03²= £5280.90 (rounded)
As you can see the amount of years will be the indices with the interest as our multiplier.
We do this again for 5 years and 10 years:
£4700x1.06⁵= £6289.70 (rounded)
£4700x1.06¹⁰=£8416.20 (rounded)
Hope this helps!
15 points please explain it to me add the answer and the work since I’m so confused on when to subtract missing lengths where and when
You didn't specify what the question was. However, I am going to assume you are looking for the missing side of the shape.
Let's call the left side "Side A" and the right side "Side B". One is longer than the other side. In this case, Side B is longer than Side A. To find the missing length, you will need to subtract Side A from Side B
Side B - Side A = Missing side
16 - 13 = 3
Therefore, the length of the missing side is 3.
"4 + 3" is an example of a(n) ___

A soccer ball is kicked toward the goal. The height of the ball is modeled by the function h(t) = - 16t^2 + 48t where t equals the time in seconds and the h(t) represents the height of the ball at time t seconds. What is the axis of symmetry, and what does it represent? Help please!!!
Answer:
x = 3/2
The axis of symmetry is located at the vertex,
which is the also the highest point in this problem...
the x component of the vertex can be calculated as -b/2a = -48/-32 = 24/16 = 6/4 = 3/2
x = 3/2

Which matrix equation can be used to solve the system?

Answer:
[tex]X= \left[\begin{array}{ccc}-4&1\\5&-1\\\end{array}\right] \left[\begin{array}{ccc}21\\20\\\end{array}\right] \\[/tex]
Step-by-step explanation:
Given the simultaneous equation
x+y=21

To write in matrix form, it must be in the form AX= b
X = A⁻¹b
A⁻¹ is the inverse of matrix A
A is a 2by2 matrix
X is the variables
b is a column matrix
The expression will therefore be written as;
[tex]A=\left[\begin{array}{ccc}1&1\\5&4\\\end{array}\right] \\\\|A| = 1(4)- 5(1)\\|A| = 4-5\\|A| = -1\\A^{-1} = -\left[\begin{array}{ccc}4&-1\\-5&1\\\end{array}\right] \\\\A^{-1} = \left[\begin{array}{ccc}-4&1\\5&-1\\\end{array}\right] \\[/tex]
Hence the required product matrix that represent X is;
[tex]X= \left[\begin{array}{ccc}-4&1\\5&-1\\\end{array}\right] \left[\begin{array}{ccc}21\\20\\\end{array}\right] \\[/tex]

Find the value of x in the isosceles triangle shown below.
Answer:
22.18 = x
Step-by-step explanation:
a^2 + (b)^2 = (x/2)^2
a = sqrt(74)
b = 7
x/2 = ?
(74)[^1/2]^2 = 74
b^2 = 7^2 = 49
74 + 49 = (x/2)^2 Substitute into a^2 + b^2 = c^2
123 = (x/2)^2 Combine like terms
(123^0.5) = x/2 Take the square root of both sides.
11.09 = x/2 Multiply both sides by 2
11.09*2 = x
22.18 = x The full length of the base of the triangle is 22.18
Answer: C
Step-by-step explanation: We only need to find the value of one of the x so just use Pythagorean theorem but simplified to do it in one step which is sqrt(4^2+6^2) which gives us sqrt(52).

Step-by-step explanation:
The method of elimination is a way of solving a system of equations. There are many steps involved in this process. First, one must manipulate one of the equations in the system by multiplying each term in it by a certain number such that one of the variables is the inverse of the other like the variable in the other equation. Then one must add the two equations. This will eliminate one of the variables in the equations. After doing so, one has to use inverse operations to solve for the other variable. Finally, one will back solve, substitute the value of the solved variable into one of the equations and solve for the remaining unknown variable.
[tex]\left \{ {{y=5x+1} \atop {y=-2x-8}} \right.[/tex]
Manipulate the system;
[tex]\left \{ {{y=5x+1*(-1)} \atop {y=-2x-8}} \right.[/tex]
Simplify,
[tex]\left \{ {{-y=-5x-1} \atop {y=-2x-8}} \right.[/tex]
Add the equations,
[tex]\left \{ {{-y=-5x-1} \atop {y=-2x-8}} \right.[/tex]
[tex]0=-7x-9[/tex]
Inverse operations,
[tex]0=-7x-9[/tex]
[tex]7x=-9[/tex]
[tex]x=-\frac{9}{7}[/tex]
[tex]x=-1\frac{2}{7}[/tex]
Backsolve,
[tex]y=-2x-8[/tex]
Substitute
[tex]y=-2(-\frac{9}{7})-8[/tex]
Simplify,
[tex]y=-2(-\frac{9}{7})-8[/tex]
[tex]y=\frac{18}{7}-8[/tex]
[tex]y=\frac{18}{7}-8\\y=-\frac{38}{7}[/tex]

1+2 = x-2+2
3 =x
The length of CD
CD = 5x-2 = 5*3 -2 = 15-2 = 13
can someone please help
Answer:
x = 13
Step-by-step explanation:
→ Remember the amount of degrees a triangle sums to
180°
→ Make an equation
8x - 44 + 8x - 44 + 8x - 44 = 180
→ Simplify
24x - 132 = 180
→ Add 132 to both sides
24x = 312
→ Divide both sides by 24
x = 13
Mike and his dad are retiling his bathroom floor. They have budgeted $200 for the tiles and supplies. The tiles cost $1.85 each and they have spent $114.90 on supplies. Write an equation and solve the equation.
Answer:
Equation: $114.90 + $1.85x = 200
Solution: They can buy 46 tiles.
Step-by-step explanation:
First, subtract 114.90 from both sides to get 1.85x = 85.10.
Divide 85.10 by 1.85 to get 46, which is the answer.

You bought 6 bars of home made soap from eBay, and weighed them on an electronic scale. They weighed 4.003, 4.006, 4.012, 4.008, 4.004, and 4.009 ounces. What is the average weight of the bars? *DON'T ROUND*
1. 4.010 ounces.
2. 4.007 ounces.
3. 24.042 ounces.
The average weight of the soap bars is 4.007 ounces. Therefore, option 2 is the correct answer.
What is the average?In maths, the average value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values. When we need to find the average of a set of data, we add up all the values and then divide this total by the number of values.
Given that, the weight of 6 home made soaps are 4.003, 4.006, 4.012, 4.008, 4.004, and 4.009 ounces.
We know that, average = Sum of all the observations/Number of observations
Here, the average = (4.003+4.006+4.012+4.008+4.004+4.009)/6
= 24.042/6
= 4.007 ounces
Therefore, option 2 is the correct answer.
