Answer:
£850
Step-by-step explanation:
We can compute the left-over amount by comparing that to the amount spent.
__
setupWritten as ratios, we have ...
spent : left-over = 3/8 : 1 -3/8 = 3/8 : 5/8 = 3 : 5
Writing this using fractions, we have ...
left-over / spent = 5 / 3
solutionSolving for left-over gives ...
left-over = spent × (5/3) = £510×5/3 = £850
Nate had £850 left over.
_____
Additional comment
Nate's money totaled £510 +850 = £1360.
The fraction spent is £510/£1360 = 3/8, as required.

Step-by-step explanation:
Part 1[tex]\textsf{Volume of a cylinder}=\sf \pi r^2 h \quad\textsf{(where r is the radius and h is the height)}[/tex]
Given:
r = 5 cmh = 4 cmπ = 3.14Substitute the given values into the formula:
[tex]\begin{aligned}\implies \textsf{Volume} & =3.14 \cdot 5^2 \cdot 4\\& = 3.14 \cdot 25 \cdot 4\\& = 3.14 \cdot 100\\& = 314 \: \sf cm^3\end{aligned}[/tex]
Part 2[tex]\textsf{Volume of a sphere}=\sf \dfrac43 \pi r^3\quad\textsf{(where r is the radius)}[/tex]
Given:
d = 10 cm ⇒ r = 5 cmπ = 3.14Substitute the given values into the formula:
[tex]\begin{aligned}\implies \textsf{Volume} & =\dfrac{4}{3} \cdot 3.14 \cdot 5^3 \\& =\dfrac{4}{3} \cdot 3.14 \cdot 125 \\& =\dfrac{500}{3} \cdot 3.14 \\& = 523.33\: \sf cm^3\:(2\:dp)\end{aligned}[/tex]

A square has a triangular hole in it. What is the area of the figure?
9 in. 3 in.
76.5 in 2
89 in 2
72 in 2
3 in.
9 in.
Answer:
76.5in²
Step-by-step explanation:
First we will find the area of the square. This is done by multiplying the side length (9in) by itself.
[tex]9 * 9 = \boxed{81}[/tex]
The area of the square is 81in².
Next we will find the area of the triangular hole. We can use the formula [tex]\frac{1}{2}bh[/tex], where b is the base of the triangle (3) and h is the height of the triangle (3).
[tex]\frac{1}{2}bh\\\frac{1}{2}(3)(3)\\\frac{9}{2}\\\boxed{4.5}[/tex]
The area of the triangle is 4.5in².
Now we can find the area of the figure by subtracting the area of the square and the area of the triangular hole.
[tex]81 - 4.5 = \boxed{76.5}[/tex]
The area of the figure is 76.5in².
That is the answer

2(x² + 3x)2x(x + 3)interest rate of 2.99% compounded monthly for a 4 year loan, find the regular monthly payments required to repay the loan.
Using it's formula, considering a loan of $10,000, the regular monthly payments required to pay off the loan will be of $221.3.
What is the monthly payment formula?It is given by:
[tex]A = P\frac{\frac{r}{12}\left(1 + \frac{r}{12}\right)^n}{\left(1 + \frac{r}{12}\right)^n - 1}[/tex]
In which:
P is the initial amount.r is the interest rate.n is the number of payments.In this problem, we have that the parameters are given as follows:
P = 10,000, r = 0.0299, n = 4 x 12 = 48.
Then:
r/12 = 0.0299/12 = 0.00249167.
Hence, the monthly payment will be given by:
[tex]A = P\frac{\frac{r}{12}\left(1 + \frac{r}{12}\right)^n}{\left(1 + \frac{r}{12}\right)^n - 1}[/tex]
[tex]A = 10000\frac{0.00249167(1+0.00249167)^{48}}{(1+0.00249167)^{48} - 1}[/tex]
A = 221.3.

A line is parallel to y=-2x-5 and intersects the point (-1,3) input the correct values into the point slope formula y-[?] = [__}(x- [__])
The equation of the line parallel to y=-2x-5 and passing through the point (-1,3) is y = -2x + 1.
What is an equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
Given that:-
A line is parallel to y=-2x-5 and intersects the point (-1,3)The equation of the new line will be:-
y - y₁ = m ( x - x₁ )
Since the line is parallel to the line y = -2x - 5 so slope will be same m = -2 now the coordinates are ( -1, 3).
y - ( 3) = -2 [( x - (-1) ]
y - 3 = -2x - 2
y = -2x + 3 -2
Y = -2x + 1
Therefore the equation of the line parallel to y=-2x-5 and passing through the point (-1,3) is y = -2x + 1.

Which inequality did Aaron solve?
|x+2| <3
Ox+2| >3
|x+3| <2
|x+31 > 2
Based on the graph that Aaron made, we can infer that the inequality he solved is | x + 2 | < 3.
What inequality was solved by Aaron?
The value of x in the graphed inequality is:
-5 < x < 1
If 2 was added to both sides, the least value would be - 3 and the highest value would be 3.
The inequality then becomes:
-3 < x < 3
This in line with the first option which is that when 2 is added to any value of x, it will be less than 3.

Answer:
A. [tex]y\leq \frac{1}{2}x+2[/tex]
Step-by-step explanation:
First, let's find the slope of the line, so we can eliminate some answers.
From point (0,2) we can go up 1 and over to the right 2 to the point of (2,3). Slope is rise over run so 1 over 2.
This eliminates C and D.
The last part is to recognize that y being less than the equation will result in the shaded region being below the line. If y was greater than the equation then the shaded region would be above the line.
Therefore, the correct answer would be A. [tex]y\leq \frac{1}{2}x+2[/tex].
Hope this helps! If you have questions about my work please let me know down in the comments!
Answer:
[tex]y\leq \frac{1}{2}x+2[/tex]
Step-by-step explanation:
The first part of finding our answer is finding the slope of the line. The image attached shows this.
[tex]\frac{rise}{run} = \boxed{\frac{1}{2}}[/tex]
This means the slope is [tex]\frac{1}{2}[/tex], removing the bottom 2 answer choices.
Now we have to choose between the [tex]\leq[/tex] and [tex]\geq[/tex] sign. Since the shaded area is below the line, it will be the [tex]\leq[/tex]. (If it was the [tex]\geq[/tex] sign, the shaded area would be above the line.) This marks the first answer as the correct answer.

Which expression is a perfect cube
Answer: some perfect cubes are
8 (2^3)
27 (3^3)
64 (4^3)
there are many perfect cubes
maybe there is more to this question?
Step-by-step explanation:
A perfect cube of a number is a number that is equal to the number, multiplied by itself, three times. If x is a perfect cube of y, then x = y3. Therefore, if we take the cube root of a perfect cube, we get a natural number and not a fraction. Hence, 3√x = y. For example, 8 is a perfect cube because 3√8 = 2.
