Emma buys a house for £300,000. She sells the house for £315,000. Calculate the percentage profit Emma makes

Answer:

the first friend

Step-by-step explanation:

your percentage is 8/15 = 53.3%

your first friend's percentage is 7/10 = 70%

your second friend percentage is 6/12 = 50%

Answer:

to compare them, you have to get the same denominator. So you change the denominator to 24 by multipling 7/12 by 2, and 5/8 by 3. Then you have 14/24 and 15/24. This means that 5/8 is greater than 7/12

Answer:

[tex]\displaystyle [6, -3][/tex]

Step-by-step explanation:

To begin this process, we will first select the second equation. Here is how the Substitution method wourks:

[tex]\displaystyle \left \{ {{3x + 5y = 3} \atop {x + 2y = 0}} \right. \\ \\ \\ \left \{ {{y = 2x + 3} \atop {x = -2y}} \right. \\ \\ 3[-2y] + 5y = 3 \hookrightarrow -6y + 5y = 3 \hookrightarrow -y = 3; -3 = y, 6 = x \\ \\ \\ \boxed{[6, -3]}[/tex]

So, you substitute [tex]\displaystyle x[/tex]for [tex]\displaystyle -2y[/tex]and continue combining like-terms until you receive the y-value. You then plug this back into the system to get the x-value, which was what you saw.

Answer:

Answer= 7

Step-by-step explanation:

the unknown number being, x, .

i think of a number ( x), double it, ( 2× x)= 2x, and add 11 to be ( 2x + 11), i get 25.

So, the equation will be:

2x + 11 = 25.

to solve it, take (+11) to the equals side and it will change to (-11), or in other words, subtract 11 on both sides.

the equation will thus remain to be:

2x = 25-11

2x = 14.................Divide both sides by 2 to remain with x

so, X = 7.

Step-by-step explanation:

for the (a) put 6 in for x in h(x)=x/3

which looks like this...

h(6)=6/3 so, h=2

not put 2 in for x in g(x)=√3

which would end up as...

g(x)=√3 since there is no x in the equation

now finally put √3 in for x in f(x)=x^3

so, f(√3)= √3^3

which is... f(x)= 3√3

[Answer] a= 3√3

Answer:

Correct choice D. 2,500 square feet

Step-by-step explanation:

Area of a rectangle

The area of a rectangle of dimensions x, y is:

A=x.y

The diagram provided in the question is to a scale of 1 inch=16 ft.

We have provided a modified diagram where all the dimensions are also shown in ft.

The longer side of the shape is 4*16=64 ft

The smaller side of the shape is 3*16=48 ft

The bottom side of the store is 2 1/4*16=36 ft

The leftmost side of the store is 1 3/4*16=28 ft

We need to find the value of x and y.

The value of x is x=64 ft - 36 ft = 28 ft

The value of y is y=48 ft - 28 ft = 20 ft

The area of the whole rectangle of dimensions 48 ft and 64 ft is:

[tex]A1=48 ft * 64 ft = 3,072 \ ft^2[/tex]

The area of the small blue rectangle is:

[tex]A2=28 ft * 20 ft = 560\ ft^2[/tex]

The area of the store is:

[tex]As=A1-A2=3,072 \ ft^2- 560\ ft^2=2,512 \ ft^2[/tex]

Rounding to the nearest 50 square feet:

[tex]\boxed{As=2,500 \ ft^2}[/tex]

Answer:

∠a= 65°, ∠b= 115°, ∠c= 25°

Step-by-step explanation:

The sum of the angles in a triangle is 180°. This is abbreviated to '∠ sum of ∆'.

∠c +55° +60° +40°= 180° (∠ sum of ∆PQR)

∠c +155°= 180°

∠c= 180° -155°

∠c= 25°

∠a +60° +55°= 180° (∠ sum of ∆PQS)

∠a +115°= 180°

∠a= 180° -115°

∠a= 65°

The sum of the angles on a straight line is 180°. It's abbreviation is 'adj. ∠s on a str. line'.

∠b +∠a= 180° (adj. ∠s on a str. line)

∠b +65°= 180°

∠b= 180° -65°

∠b= 115°

Answer:

Step-by-step explanation:

The equation that represents the basketball team raising money is a linear equation

The equation that represents the total amount raised is 10x + 15y = 3050

From the question, we have the following parameters

A linear equation is represented as;

Ax + By = C

So, the equation that represents the total amount raised would be 10x + 15y = 3050

Hence, the equation that represents the total amount raised is 10x + 15y = 3050

Step-by-step explanation:

Area of circle = πr², π = 22/7 or 355/133. Here it is said to use '3.14'. I will use the same.

Volume = cross-section area * height

Cross-section area of bigger one = π(3m)²

Volume = π(3m)² * height

= 9π * 5 m³ = 45π m³

Cross-section area of smaller one= π(1m)²

Volume = π(1m)² * height

= π * 5 m³ = 5π m³

Since a large part(cylinder of 1 m is not here):

Required volume = total volume - volume of smaller circle(cylinder)

= 45π - 5π m³

= 40π m³ = 40(3.14) m³

= 125.6 m³

To solve this question, just divide.
