Answer:
£151.20
Step-by-step explanation:
20%= 100%divided by 5
To find 100% from 20% you x by 5
so you times 30.24 by 5
30.24x 5 = 151.2
So the answer is £151.20
interest percentage rate would be 1.6754%
The interest rate for the account is 1.68%
What is interest rate?The interest rate is the amount a lender charges a borrower and is a percentage of the principal the amount loaned.
Given that,
Sue invests £9000 in an account for one year.
She pays £30.24 at a rate of 20%
So, 20% of the interest = £30.24
Let the interest be x,
X0.2 = 30.24
X = £151.2
The total interest was = £ 151.2
The rate R at which generated this interest =
R = (100 × 151.2)/(1 × 9000)
R = 15120/9000
R = 1.68%
Hence, the interest rate = 1.68%

Find the surface area of the prism.
Answer:
78 square ft.
The answer is 75 ft
explanation
12ft x 2.5ft = 30ft
12ft x 2ft = 24ft
12ft x 1.5ft = 18ft
1.5ft x 2ft = 3ft
30 + 24 + 18 + 3 = 75
The bar graph shows the results of rolling a number cube (a die) 50 times. What is the probability of rolling an odd number? How does this compare with the theoretical probability of rolling an odd number?
Experimental Probability. Theoretical Probability
P(odd) = % P(odd) = %
Answer:
[tex]\fbox{\begin{minipage}{12em}52 percent and 50 percent \end{minipage}}[/tex]
Step-by-step explanation:
Given (as shown in graph):
The results of rolling a number cube (a die) 50 times.
Rolling 1: 10 times
Rolling 2: 4 times
Rolling 3: 8 times
Rolling 4: 11 times
Rolling 5: 8 times
Rolling 6: 9 times
Solve for:
The probability of rolling an odd number (1, 3, 5).
Solution:
Step 1: Define the formula for calculating the probability
P = number of elements/total number of elements
Step 2: Perform the calculation
1) Theoretically, a fair die of 6 sides would give the equal chance to obtain 1, 2, 3, 4, 5, 6.
According to the formula in step 1, the number of elements in both cases are the same (odd: 1, 3, 5 => 3 elements, even: 2, 4, 6 => 3 elements, the total element is 1, 2, 3, 4, 5, 6 => 6 elements).
=> P(obtain odd number theoretically) = P(obtain even number theoretically) = 50%
2) Experimentally, apply the formula in step 1, we have:
The number of elements = Times of rolling 1 + Times of rolling 3 + Time of rolling 5 = 10 + 8 + 8 = 26
The total number of rolling: 50
=> P(obtain odd number in experiment) = 26/50 = 0.52 = 52%

An employee at a homemade wooden toy store earned $860 over the past week. The employee needs to pay 14% for Federal Income Tax and 3% for State Income Tax, both on the initial amount he earned. How much will the employee earn after paying both taxes?
Answer:
$713.8
Step-by-step explanation:
14%of 860 = 120.4
3% of 860 = 25.8
so, subtract the sum of the above 2 values from 860.
860 - (120.4+25.8) = 860-146.2 = 713.8

it depends how many games you want. If you want 1 game for the xbox then its $174 but if you want a ps4 with a game then its $200. I would go with the xbox.
the volume of a cone is 540pi. work out the height of the cone.
Answer:
I would need the radius of the cone to answer this completely, bit I can get you super close and explain it.
Step-by-step explanation:
The formula for a cone is
[tex]\pi \times r {}^{2} \times \frac{h}{3} [/tex]
From there, I started plugging in numbers. I set this equation equal to 540pi because both if them are the volume, so they are equal and I simplified as much as I could from there. First off, the pi cancel each other out since they're on both sides of the equation. From there you have this equation:
[tex]r {}^{2} \times \frac{h}{3} = 540[/tex]
Then, I multiplied both sides by 3 to get rid of the fraction on the left side of the equation:
[tex]r {}^{2} h = 1620[/tex]
Finally, I got rid of the "squared" by putting a square root over both sides if the equation, getting this:
[tex]r \times h = 40.249[/tex]
If I knew the radius. I could get the answer by dividing both sides by the radius.
Good luck!

At which root does the graph of f(x) = (x – 5)3(x + 2)2 touch the x-axis?
-5
-2
Ο Ο Ο Ο
2
5
Answer:
At x = -2 the graph of this polynomial will touch the x-axis.
Step-by-step explanation:
Recall the behavior difference between power functions of even and odd power. Odd powers are associated with the crossing of the x-axis, while even powers are associated with "touching" of the x axis.
in this cases, since they give you the function in factor form, the actual roots (x-values where the function adopts value zero) of the function are evident :
[tex]f(x)=(x-5)^3\, (x+2)^2[/tex]
It has a root at x = 5 [notice that at such x-value the factor (x-5) becomes zero], and this root is of multiplicity "3" (given by the power associated with the binomial factor for this root)
and has another root at x = -2 [notice that at such x-value the factor (x+2) becomes zero], and this root is of multiplicity "2" (given by the power associated with the binomial factor for it)
It is just the second root analyzed the one that shows an even power (2) associated to its binomial factor, and therefore it is at x= -2 that the graph of this function will show as "touching" the x axis.

the area of a right angled triangle is 600cm^.if base of the base of the exceeds the altitude by 10,find the dimensions of the triangle
Answer:
b => base => 40 cm
h => altitude => 30 cm
A = h*b/2
h=b-10
600=(b-10)b/2
600 = (b^2-10b)/2
1200=b^2-10b
b^2-10b-1200=0
(b-40)(b+30)=0
b=40 cm
h=b-10 = 40-10=30

The length is 1.4 inches and the width is 0.6 inch
SUB
Answer:
The length is 35 inches and the width is 15 inches.
Step-by-step explanation:
First work of the real length of the field. Given is the ratio of drawing to original and the dimensions of the drawing. so in real life the lawn measures 70 inches in length and 30 inches in width.
Now, we have to divide this in the ratio 1:2, which gives
The length of 35 inches and the width of 15 inches.

The perimeter of the given triangle is
Answer:
~73.68
Step-by-step explanation:
In the right triangle with one angle = 45 deg
=> Isosceles right triangle
=> a = b = hypotenuse/sqrt(2) = (12sqrt(2))/sqrt(2) = 12
In other right triangle with 3 sides are a, c, and d, we have:
sin (30 deg) = a/d
=> d = a/sin(30 deg) = 12/(1/2) = 12 x 2 = 24
Othwise, cosine (30 deg) = c/d
=> c = d x cos(30 deg) = 24 x sqrt(3)/2 = 12sqrt(3)
=> The perimeter of the biggest triangle is calculated by:
P = 12sqrt(2) + b + c + d = 12sqrt(2) + 12 + 12sqrt(3) + 24 = ~73.68

A ball is being inflated at a rate that can be modeled by the function V(t) = 10t, where t is the number of seconds spent inflating the ball. The radius at a given volume can be modeled by the function r(V)=^3√3V/4pi.
Which composite function can be used to determine the radius of the ball depending on the number of seconds spent inflating the ball?
Answer:
Correct option: second one
Step-by-step explanation:
To find the composite function r(V(t)) (radius of the ball in relation to time being inflated), we just need to use the value of the equation V(t) in each value of V in the function r(V).
[tex]V(t) = 10t[/tex]
[tex]r(V)=\sqrt[3]{3V/4\pi}[/tex]
[tex]r(V(t))=\sqrt[3]{3V(t)/4\pi}[/tex]
[tex]r(V(t))=\sqrt[3]{3*10t/4\pi}[/tex]
[tex]r(V(t))=\sqrt[3]{30t/4\pi}[/tex]

Answer:
I will answer this in English.
a) here you written 208 = (2^6)*3, while in the table you can see 5 times the number 2 and 2 times the number 3, this means that:
208 = 2^5*3^2
then we would have:
√208 = √(2^5*3^2) = 3*2*√2 = 6*√2
b) This time is correct that:
1568 = 2^5*7^2
but the simplification in the square root is not correct. (√(2^5) is not equal to 2^2)
as √(2^5*7^2) = √(2*2^4*7^2) = 2^2*7*√2 = 4*7*√2 = 28*√2

Answer:

Step-by-step explanation:
[tex]\sqrt[4]{4x+10}[/tex] = 4x+10 ^1/4
[tex]\sqrt[4]{9+7x}[/tex]= 9+7x^1/4
Since they are under the same root, you can combine them under the root.
Then you change the +/- sign of one side of the equation to move to the other side of the equation.
To get....[tex]\sqrt[4]{-3x+1}[/tex]=0
^4 both sides to get..
-3x+1=0
Move 1 to the other side...
-3x=-1
divide both sides by -3
