Answer:

A

Step-by-step explanation:

Jason's initial share was £360 before giving 45% to his mum. The total money shared was £1800. Katy receives £864 more than Jason.

First, we need to find out how much money Jason initially received before he gave away 45% to his mum. Since £198 is 55% of his initial share (100% - 45% = 55%), we can find the full amount by calculating £198 ÷ 0.55. This gives us Jason's total share before he gave any money to his mum, which is £360.

Given that Jason gets 1/5 of the money, we multiply his share by 5 to find the total amount of money shared, which is £360 × 5 = £1800. Since Jason took his 1/5 share, the remaining 4/5 is shared between Katy and Leonard in the ratio 17:3. Hence, the combined share of Katy and Leonard is 17 + 3 = 20 parts of the remaining money.

To find out how much each part is worth, we divide the remaining money by 20. The remaining money is 4/5 × £1800 = £1440, so each part is worth £1440 ÷ 20 = £72.

Hence, Katy receives 17 parts × £72 = £1224, and Leonard receives 3 parts × £72 = £216. The difference in the amount received by Katy compared to Jason is £1224 - £360 = £864, so Katy receives £864 more than Jason.

We are asked to find 7 is what percent to 30.

We will use proportions to solve our given problem.      

Let us assume that 7 is n% of 30. So we can set a proportion as:

[tex]\frac{n}{100}=\frac{7}{30}[/tex]

Let us solve for n.

[tex]\frac{n}{100}\cdot 100=\frac{7}{30}\cdot 100[/tex]

[tex]n=\frac{7}{3}\cdot 10[/tex]

[tex]n=\frac{70}{3}[/tex]

[tex]n=23.333[/tex]

Therefore, 7 is [tex]23.333\%[/tex] of 30.

Answer:

(x - 3)(x + 8)

Step-by-step explanation:

x² + 5x - 24 =

= x² + 8x - 3x - 24

= x(x + 8) - 3(x + 8)​

= (x - 3)(x + 8)

Answer:

(x + 8)(x - 3)

Step-by-step explanation:

Assuming you require to factor the expression.

Given

x² + 5x - 24

Consider the factors of the constant term (- 24) which sum to give the coefficient of the x- term (+ 5)

The factors are + 8 and - 3, since

8 × - 3 = - 24 and 8 - 3 = + 5, thus

x² + 5x - 24 = (x + 8)(x - 3) ← in factored form

Answer:

[tex]\frac{1}{15}[/tex] of a gallon.

Step-by-step explanation:

It's just:

[tex]\frac{1}{3} *\frac{1}{5} =\frac{1}{15}[/tex]

So [tex]\frac{1}{15}[/tex] of a gallon on each sundae.

The chocolate sauce on each sundae is B) 1/15.

The division is one of the four basic mathematical operations, the other three being addition, subtraction, and multiplication.

Now it is given that,

Volume of chocolate sauce = 1/3 gallon

Number of chocolate sundaes = 5

So, chocolate sauce is on each sundae = Volume of chocolate sauce / Number of chocolate sundaes

⇒ chocolate sauce is on each sundae = (1/3)/5 gallon

⇒ chocolate sauce is on each sundae = 1/15 gallon

Thus, the chocolate sauce on each sundae is B) 1/15.

Answer:

Your answer would be C

Step-by-step explanation:

Answer:

20.

Step-by-step explanation:

We can begin by calculating 20% of 6:

0.2 × 6= 1.2

If 1.2 is 6% of the number, we can set up an equation like this:

0.06x = 1.2

Now, divide on both sides, giving us:

x= 20.

Answer:A

Step-by-step explanation: this is aquadratic equation and can be solved by using factorisation.

To use factorisation method we need to look for two numbers that when we muliply them we get +1 and when we add them we get -2

So that is -1 and -1

-1*-1=+1

-1+(-1)=-2

so now we substitube -2x with the two known factors which will give us;

x²-1x-1x+1=0

now we factorise this equation. which will give us;

x(x-1)-1(x-1)=0

now we pick the factors outside the bracket and the factors inside the bracket, which will give us;

(x-1)(x-1)=0

so;

x-1=0 and

x-1 =0

take 1 to the other side, which will give us;

x=1 two timesA

We have been given an equation [tex]w=\frac{3}{2}t-1[/tex] that represents umber of walls, w, that Joe can paint in t hours. We are asked to find the number of hours it will take Joe yo paint 7 walls.

To solve our given problem, we will substitute [tex]w=7[/tex] in our given equation as:

[tex]7=\frac{3}{2}t-1[/tex]

Let us solve for t.

[tex]7+1=\frac{3}{2}t-1+1[/tex]

[tex]8=\frac{3}{2}t[/tex]

[tex]8\cdot\frac{2}{3}=\frac{2}{3}\cdot\frac{3}{2}t[/tex]

[tex]\frac{8\cdot2}{3}=t[/tex]

[tex]\frac{16}{3}=t[/tex]

Therefore, it will take [tex]\frac{16}{3}[/tex] hours Joe to paint 7 walls.

Betsy is incorrect as he wrote [tex]3^4[/tex] = 12 but it should be 81.

Exponents and powers are ways used to represent very large numbers or very small numbers in a simplified manner.

For example, if we have to show 3 x 3 x 3 x 3 in a simple way, then we can write it as [tex]3^4[/tex], where 4 is the exponent and 3 is the base.

Given:

Expression: (8 + 18) x [tex]3^4[/tex]

Now, solving the Above Expression

(8 + 18) x [tex]3^4[/tex]

= 26 x [tex]3^4[/tex]

= 26 x ( 3.3.3.3)

= 26 x 81

= 2106

Betsy make a mistake as he wrote [tex]3^4[/tex] = 12 but it should be 81.

Answer:

Adult = 39

Children = 36

Step-by-step explanation:

The total number of people = 75

Cost of adult ticket = $2.75

Cost of children ticket = $2.25

Total receipts = $188.25

Let the number of adult = x

Let the number of children = y

X + y = 75 ......equation (i)

(X × 2.75) + (y × 2.25) = 188.25

2.75x + 2.25y = 188.25.......equation (ii)

To find the numbe of adult and children that attended, we'll have to solve equation (i) and (ii) simultaneously.

From equation 1,

X + y = 75

X = 75 - y......equation(iii)

Put equation (iii) into equation (ii)

2.75*(75 - y) + 2.25y = 188.25

206.25 - 2.75y + 2.25y = 188.25

206.25 - 0.5y = 188.25

Collect liketerms

0.5y = 206.25 - 188.25

0.5y = 18

Y = 18 / 0.5

Y = 36

Put y = 36 into equation (i)

X + 36 = 75

X = 39

Therefore the number of adult is 39 while that of children is 36.

The area of the picture after being enlarged by a scale factor of 2.5 will be 250 square inches, which is determined by multiplying the new dimensions (12.5 inches by 20 inches). The correct answer is option b) 250 in².

To find the new area of the picture after enlargement, we use the scale factor. First, we find the original area of the picture by multiplying the width by the height: 5 inches * 8 inches = 40 [tex]in^2[/tex]. The photographer wants to enlarge the picture by a scale factor of 2.5. This means that both the width and the height of the picture will be multiplied by 2.5.

So the new width will be 5 inches * 2.5 = 12.5 inches and the new height will be 8 inches * 2.5 = 20 inches. Now we can calculate the enlarged picture's area:

12.5 inches * 20 inches = 250 [tex]in^2[/tex]. Therefore, the area of the picture after enlargement will be 250 square inches, which corresponds to option (b).
