Answer:

Dylan should receive £75

Step-by-step explanation:

We know that

Abby, Neil, and Dylan share money in the ratios 2:4:5

This means that for every £2 that Abby has, Neil has £4, and Dylan has £5.

From this, we also know that for every £4 that Neil has, Dylan has £5.

Now we know that Neil receives £60

For each group of £4, Dylan will have £5.

Then we need to count how many times £4 is on £60, this is equal to:

£60/£4 = 15

And for each one of these, Dylan should receive £5, this is:

15*£5 = £75

Answer:

How is genetic information passed from parents to offspring in humans?

But when people talk about genes being passed on, they generally don't mean genes being passed on from cell to cell during cell division. Instead, they usually mean genes being passed on from parents to children. This is known as "heredity" or "inherited genes."

Answer:

26.3 grams

Step-by-step explanation:

57% of fiber is 15 grams. To find 1% you would divide 15 by 57 which is 0.2631578947. Now multiply 1% by 100 to get 100% fiber. The amount of fiber needed per day is 26.31578947 (the rounded answer is 26.3)

Answer:

Juan bought 139 tickets and Alex bought 204.

Step-by-step explanation:

Suppose Juan bought a total of [tex]x[/tex] tickets. Then Alex bought 65 more, which is [tex]x+65[/tex]. The sum of both totals is [tex](x)+(x+65) = 2x + 65[/tex], but we are also given that this is equal to 343. So [tex]2x+65 = 343[/tex], and as such [tex]2x = 343-65=278[/tex], so [tex]x = \frac{278}{2} = 139[/tex]. Therefore, Juan bought 139 tickets and Alex bought 65 more, which is 204.

Answer:

2, 4 and 8

Step-by-step explanation:

Using the rule of exponents/ radicals

[tex]a^{\frac{m}{n} }[/tex] ⇔ [tex]\sqrt[n]{a^{m} }[/tex]

(a)

[tex]8^{\frac{1}{3} }[/tex] = [tex]\sqrt[3]{8}[/tex] = 2

(b)

[tex]8^{\frac{2}{3} }[/tex] = [tex]\sqrt[3]{8^{2} }[/tex] = 2² = 4

(c)

[tex]16^{\frac{3}{4} }[/tex] = [tex]\sqrt[4]{16^{3} }[/tex] = 2³ = 8

Answer:

Peter rents 6 of the rafts seating 3 people, and 7 of the rafts seating 5 people.

Step-by-step explanation:

Let [tex]x[/tex] denote the number of rafts seating 3 people and [tex]y[/tex] the number of rafts seating 5 people. The total number of rafts is 13, so [tex]x+y=13[/tex]. We can also assume that every raft is filled to the brim (it isn't stated explicitly though, but it's probably the intention of the question maker), so [tex]3x+5y=53[/tex].

It's always a good idea to put these equations under each other:

[tex]\left \{ {{x+y = 13} \atop {3x+5y=53}} \right.[/tex]

We can subtract the first equation three times from the second one to obtain [tex](3x+5y)-3(x+y) = 53 - 3(13)\\3x-3x + 5y - 3y = 53 - 39\\2y = 14\\y=\frac{14}{2} = 7[/tex]

Now, substitute this found value for [tex]y[/tex] into [tex]x+y = 13[/tex] and we see that [tex]x=6[/tex]. We are now done: Peter rents 6 of the rafts seating 3 people, and 7 of the rafts seating 5 people.

The expressions which is equal to 10⁵ are 10³. 10² and 10 . 10 . 10 . 10 . 10.

Expressions are mathematical statements which consist of two or more terms and terms are connected to each other using mathematical operators like addition, multiplication, subtraction and so on.

The given expression is 10⁵.

(10⁴)¹ = 10⁴

We have a rule of exponents,

xᵃ . xᵇ = xᵃ⁺ᵇ

10³. 10² = 10³ ⁺ ² = 10⁵

1 / 10⁵ = 10⁻⁵

(10³)² = 10^(3 × 2) = 10⁶

10 . 10 . 10 . 10 . 10 = 10⁵

Hence the equivalent expressions are 10³. 10² and 10 . 10 . 10 . 10 . 10.

Answer:

m∠DAB = 101°

x = 7

y = 12

Step-by-step explanation:

Properties of a parallelogram,

1). Opposite sides of a parallelogram are equal and parallel.

2). Opposite interior angles are equal in measure.

3). Consecutive interior angles are supplementary.

By the first property,

BC ≅ AD

2x + 4 = 3x - 3

3x - 2x = 4 + 3

x = 7

AB ≅ CD

2y + 10 = 3y - 2

3y - 2y = 10 + 2

y = 12

By second property,

m∠ABC = m∠ADC

2z + 15 = 3z - 17

3z - 2z = 15 + 17

z = 32

Therefore, m∠ADC = (3z - 17)°

                                = 3(32) - 17

                                = 96 - 17

                                = 79°

By third property,

m∠ADC + m∠DAB = 180°

79° + m∠DAB = 180°

m∠DAB = 180° - 79°

m∠DAB = 101°

Answer:

You can calculate net change by subtracting the current day's closing price for an asset from the closing price of the previous day!

Step-by-step explanation:

(What net change is) The net change theorem states that when a quantity changes, the final value equals the initial value plus the integral of the rate of change. Net change can be a positive number, a negative number, or zero.

Answer:

A) -13, -7, -3, 0, 3     B) -100, -99, -8, -25/3, -2

Step-by-step explanation:

3)Ordered from least to greatest is:  -13, -7, -3, 0, 3

(The higher the negative the "smaller" it is)

4) -100, -99, -8, -25/3, -2

These numbers are listed in order from least to greatest with the error being  -25/3. This equals -8.333 and should be in front of the -8 because it is a lesser value. The correct order would be:  -100, -99, -25/3, -8, -2 but your answer asks for one error so use the numbers above.
