Answer:

39

Step-by-step explanation:

1st grade:

2nd grade:

3rd grade:

4th grade:

5th grade:

Since the total students have been given, we just have to find the percentage of the 205 students that are 5th graders (19%).

So this can be found out:

19% of 205

Solution:

Always use this formula to find a percentage:

% / 100 = Part / Whole replace the given values:

19 / 100 = Part / 205

Cross multiply:

19 x 205 = 100 x Part, or

3895 = 100 x Part

Now, divide by 100 and get the answer:

Part = 3895 / 100 = 38.95

Since decimal cant be a whole number round to nearest tenth:

First note that 38.95 has two parts. The integer part to the left of the decimal point and the fractional part to the right of the decimal point:

To round 38.95 to nearest tenth means to round the numbers so you only have one digit in the fractional part.

We use the following rules to round 38.95 to the nearest tenth:

With 38.95, rule C applies and the answer is:

39.0

Ratio remains same

Answer:

(1, -5)

Step-by-step explanation:

From the information that is given (1, -5) seems to be the logical answer since we have (1, 5), (-1, 5), and (-1, -5). 1 has been negative twice, 5 has been positive twice so to make things right add a positive +1 and a negative -5

Answer:

60 kg of cement, 180 kg of sand and 240 kg of gravel

Step-by-step explanation:

x : 3x : 4x

If you turn this into an equation, it becomes x + 3x + 4x = 480

8x = 480

x = 60

60 is the amount for the cement, for the sand and gravel multiply this answer by 3 and the other by 4, you should get 180 and 240

Answer:

y=4/3x+4

Step-by-step explanation:

Answer:

y=-2x-4

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(2-(-16))/(-3-6)

m=(2+16)/-9

m=18/-9

m=-2

y-y1=m(x-x1)

y-(-16)=-2(x-6)

y+16=-2(x-6)

y=-2x+12-16

y=-2x-4

Answer:

Neither

Step-by-step explanation:

y2 - y1          -16 - 2           -18

----------   =   -----------   =   --------   =   2

x2 - x1          -3 - 6              -9

y = mx + b

-16 = 2(6) + b

-16 = 12 + b

-12   -12

-28 = b

y = 2x - 28

y = mx + b

2 = 2(-3) + b

2 = -6 + b

+6  +6

8 = b

y = 2x + 8

Answer:

M= 90 degrees

L= 47 degrees

K = 43 degrees

Step-by-step explanation:

90+3x+28+2x+37=180

simplify and place x by itself to get

x= 5

input x into both angle equations

and it already tells you M is equal to 90 degrees due to the box symbol.

Answer:

Given ,

Ahmed's age = " m " years.

Also ,

age of Ahmed's sister = 2 × m = 2m years

According to Question ,

age of ahmed + age of his sister = 27

[tex]\bold{m + 2m = 27 }\\ \bold{3m = 27 }\\ \bold{m = \cancel{\frac{27}{3} }} \\ \\ \fbox\blue{m = 9}[/tex]

therefore ,

age of Ahmed = 9 years.

age of Ahmed's sister = 2m = 2 ( 9 ) = 18 years.

hope helpful~

Age of Ahmed is 9 years

Age of Ahmad's sister is 18 years

In the question it is given that Ahmed is of m years.

Her sister is twice as old as he.

Now in the question it is given that sum of their ages is 27. So lets add the age of Ahmed and his sister and keep it equal to 27 inorder to get the value of m.

Age of Ahmed + Age of his sister = 27

m + 2m = 27

3m = 27

m = 27 / 3

m = 9

★ Age of Ahmed:-

Age of Ahmed = m

Age of Ahmed = 9 years

★ Age of his sister:-

Age of Ahmad's sister = 2m

Age of Ahmad's sister = 2 × 9

Age of Ahmad's sister = 18 years

Answer:

2&4+44-24÷333×6385

Step-by-step explanation:

so it can be a cardinal product

If functions  f(5x)=f(5)+f(x) then f(1)=0.

A relation is a function if it has only One y-value for each x-value.

Given that f(5x)=f(5)+f(x)

f of five times of x equal to f of five plus f of x.

We need to prove f(1) is equal to zero.

f(5x)=f(5)+f(x)

Let plug in x value as one

f(5×1)=f(5)+f(1)

f(5)=f(5)+f(1)

Subtract f(5) from both sides

f(1)=0

Hence, if functions  f(5x)=f(5)+f(x) then f(1)=0.

Step-by-step explanation:

[tex]4 {}^{2x + 3} = 1[/tex]

In order for exponents to be equal, they must have the same base and same power.

So what exponet can we raise 4 to in order to get 1.

Remeber that

[tex]a {}^{0} = 1[/tex]

so

[tex]4 {}^{0} = 1[/tex]

,So we finally have

[tex]4 {}^{2x + 3} = 4^{0} [/tex]

Set the exponents equal to each other

Answer:

There would be 173,535 lionfish after 6 years.

Step-by-step explanation:

Since lionfish are considered an invasive species, with an annual growth rate of 67%, ya scientist estimates there are 8,000 lionfish in a certain bay after the first year, A) to write the explicit equation for f (n) that represents the number of lionfish in the bay after n years; B) determine how many lionfish will be in the bay after 6 years; and C) if scientists remove 1,200 fish per year from the bay after the first year, determine what is the recursive equation for f (n); the following calculations must be performed:

A)

8000 x 1.67 ^ n = f  

B)

8000 x 1.67 ^ 6 = X

8000 x 21.691961596369 = X

173,535.692770952 = X  

C)

(8000 - 1200 x 1 ^ n) x 1.67 ^ n = f

Therefore, there would be 173,535 lionfish after 6 years.

Answer: his is a simple as well as an interesting question. CASE I: y = 25. Consider this a² = |a|. Given y = 25, we can write like this way,. y = -5/2.

Step-by-step explanation:

Answer:

-1/2

Step-by-step explanation:

We are given the exponential equation:—

[tex]\displaystyle \large{125=(\frac{1}{25})^{y-1}}[/tex]

First, use a law of exponent [Quotient Rules] to convert RHS:—

[tex]\displaystyle \large{125=(25^{-1})^{y-1}}[/tex]

Then convert both bases to base 5:—

[tex]\displaystyle \large{5^3 = (5^{-2})^{y-1}}[/tex]

Use another law of exponent [Power] to multiply the exponent of RHS:—

[tex]\displaystyle \large{5^3 = 5^{-2y+2}}[/tex]

Now that both sides have same base, solve the equations with exponent:—

[tex]\displaystyle \large{3=-2y+2}\\\displaystyle \large{1=-2y}\\\displaystyle \large{y=-\frac{1}{2}}[/tex]

Therefore, the value of y is:—

[tex]\displaystyle \large{\boxed{-\frac{1}{2}}}[/tex]

__________________________________________________________

Summary

This section includes an important or necessary explanation, summary or formulas that was used in the explanation above.

  Laws of Exponent

Power of Power Rules:—

[tex]\displaystyle \large{(a^m)^n = a^{mn}}[/tex]

Quotient Rules:—

[tex]\displaystyle \large{a^{-n}=\frac{1}{a^n}}[/tex]

Note that the above, Quotient Rules, is derived from:—

[tex]\displaystyle \large{\frac{a^m}{a^n} = a^m \div a^n = a^{m-n}[/tex]

But when m = 0 the numerator becomes 1.

  Exponential Equation

When solving an Exponential Equation, the goal is to convert both sides having the same base.

When both sides have same base, take both exponents of both sides to solve the equation.

What makes Europa a potential home to extraterrestrial life? *

Europa is the sixth closest moon of the planet Jupiter, and one of the largest moons in the solar system. Europa is slightly smaller than the Earth’s moon and has a tenuous atmosphere compared primarily to oxygen. The surface of Europa is composed of water and is one of the smoothest in the solar system. Scientists suggest that it is possible Europa has an ocean of liquid water beneath its surface, making it a strong candidate for extraterrestrial life. It is also predicted that heat energy from tidal flexing may cause oceans to remain liquid and drives geological activity similar to plate tectonics on Earth.
