Hi :)

To find percentage, divide 56 by 80 and multiply by 100

To remember this, know that since 56 is of 80, of/number x 100  56/80 x 100

You should get something like 70, which happens to be your answer, 70%

Hope this helps,

Answer:

B. 4

Step-by-step explanation:

(g o f)(x) means that we put the expression for f(x) in for x in g(x):

(g o f)(x) = g(f(x)) = (x - 2)²

We want to find (g o f)(4), so plug 4 in for x:

(g o f)(x) = (4 - 2)² = 2² = 4

The answer is thus B.

Answer:

none

Step-by-step explanation:

1/3=0.33

3/5=0.6

4/15=0.26

5/6=0.83

4/1000=0.004

13/4=3.25

Answer:

To find a repeating decimal, divide the numerator by its denominator to find out if it is repeating.

1/3 = 0.333333...

3/5 = 0.6

4/15 = 0.26666...

5/6 = 0.833333...

4/1000 = 0.004

1 3/4 = 1.75

So, 1/3, 4/15, and 5/6 are repeating decimals.

I'm sorry if I misunderstood.

Good luck mate! :)

Answer:

Step-by-step explanation:

Given the amount of water in millilitres to be 10 ml

Time taken for the water to flow = 8.5 seconds

Rate of flow in ml/sec = amount of water (in ml)/Time taken(in secs)

Rate of flow in ml/sec = 10ml/8.5scs

To express the resulting value in litres per minute, we will use the following conversion:

1 millilitre = 10⁻³litres

60secs = 1 minute

Converting 10ml to litres:

If 1 millilitre = 10⁻³litres

10 millilitres = (10*10⁻³)litres

Converting 8.5secs to minute:

If 60secs = 1 minute

8.5secs = (8.5/60)minutes

8.5secs = 0.1417 minutes

10ml/8.5scs in litre/sec:

10ml/8.5scs = (10*10⁻³)litres/0.1417 minutes

10ml/8.5scs  = (0.01/0.147)litres/min

10ml/8.5scs  = 0.07litres/minute (to the nearest hundredth)

Hence the rate of flow in liters per minute to the nearest hundredth is 0.07litres per minute.

Answer:

Step-by-step explanation:

f(x) = x - 2

g(x) = x²

In order to find (fog)(-1) we must first find (fog)(x)

To find (fog)(x) substitute the g(x) into f(x) that's for every x in f (x) replace it with

g (x).

That's

(fog)(x) = x² - 2

To find (fog)(-1) substitute the value of x that's - 1 into (fog)(x)

We have

(fog)(-1) = (-1)² - 2 = 1 - 2 = - 1

Step-by-step explanation:

y=-3/4 ÷ -4/3

y=+9/16‌ ‌ ‌ ‌ ‌ ‌ ‌ ‌ ‌ ‌ ‌

Answer:

So we have this equation:

[tex]\frac{-4}{3y}=\frac{-3}{4}[/tex]

We can multiply both sides by 4 and 3y:

[tex]\frac{-4*4*3y}{3y}=\frac{-3*4*3y}{4}[/tex]

[tex]-4*4=-3*3y[/tex]

[tex]-16 = -9y[/tex]

Now we divide both sides by 9:

[tex]\frac{-16}{-9}=y[/tex]

And we can remove the minus signs:

[tex]\frac{16}{9}=y[/tex]

If you mean [tex]\frac{-4}{3}y=\frac{-3}{4}[/tex]:

[tex]-4y*4=-3*3[/tex]

[tex]-16y = -9[/tex]

[tex]y=\frac{9}{16}[/tex]

Answer:

-10

Step-by-step explanation:

Let x = number

10 less than a number is the same number doubled

x-10 = 2x

Subtract x from each side

x-10-x = 2x-x

-10 = x

The number is -10

Answer is D

Answer:

Mary: £20

Tom: £16

Step-by-step explanation:

Let x=the number of £ Mary has and y=number of £ Tom has.

x+y=36  ==>x=36-y

x/2+2y=42 ==> x+4y=84

36-y+4y=84

36+3y=84

3y=48

y=16

x+y=36, so x+16=36, so x=20

Answer:

all not negative

Step-by-step explanation:

every one not negative is a ratio

By calculating the slope, we can say that the table best describes the change in Y with respect to X.

Slope is calculated by finding the ratio of the "vertical change" to the "horizontal change" between (any) two distinct points on a line.

Equation of line is y = mx + c where m is the slope.

Similarly, in y = 0.25x, 0.25 is the slope.

For the table, we need to calculate slope.

[tex]m = \frac{y2 - y1}{x2 - x1}[/tex]

[tex]m = \frac{0.8-0.4}{2-1}[/tex]

m = 0.4

As we compare, it is clear that the slope calculated from the table is greater.

Answer:

See below (I hope this helps!)

Step-by-step explanation:

When dividing exponents of the same base, we can simply subtract the powers so the new power would be 6 / 7 - 2 / 7 = 4 / 7, hence we need to write [tex]r^{\frac{4}{7} }[/tex] as a radical. When writing fractional exponents as radicals, the denominator of the fractional exponent is the index of the radical and the numerator is the exponent of the base inside the radical, hence, our answer is [tex]\sqrt[7]{r^{4} }[/tex].

Answer : The grain of sand is 50 times greater than the phytoplankton.

Step-by-step explanation :

As we are given that:

Size of phytoplankton = 2 × 10⁻⁶ in

Size of sand grain = 1 × 10⁻⁴ in

Now we have to determine how many times longer the grain of sand is than the phytoplankton.

We are dividing the sand grain size by the phytoplankton size.

This can be done by equating it as follows:

[tex]\frac{\text{Size of sand grain}}{\text{Size of phytoplankton}}=\frac{1\times 10^{-4}in}{2\times 10^{-6}in}[/tex]

[tex]\frac{\text{Size of sand grain}}{\text{Size of phytoplankton}}=50[/tex]

Therefore, the grain of sand is 50 times greater than the phytoplankton.

Answer:

A

Step-by-step explanation:

The domain of a graph is the span of x-values (or t-values in this case) it covers.

From the graph, we can see that the graph stretches from t=0 to t=14.

Also, note that since the endpoints are closed circles, we will include them within our domain.

Therefore, our domain is all values greater than or equal to 0 and less than or equal to 14.

In set notation, this is:

[tex]\{t|0\leq t\leq 14\}[/tex]

So, our answer is A

Answer: -50

Step-by-step explanation:

-20 + -30 = -50

The total change in temperature that Dana recorded will be -50 or a drop of 50.

The number system is a way to represent or express numbers.

A decimal number is a very common number that we use frequently.

Since the decimal number system employs ten digits from 0 to 9, it has a base of 10.

As per the given,

First temperature drop = -20

Second temperature drop = -20

Total drop = -20 - 20 = -40

Hence "The total change in temperature that Dana recorded will be -50 or a drop of 50".
