there are 20 students in mr.clarks fourth grade class there are 5 times as as many students in the entire fourth grade class as there are in mr.clacks. which equation can be used to determine the number of students,n, in the entire fourth grade?

n= 20(5)

100 kids in the fourth grade

or

there are 140 kids in the 4 th grade

Step-by-step explanation:

the equation is n=20(5)

because 20(5) is the same as 20×5 so that 8s the equation

Answer:

145°

Step-by-step explanation:

35+(5x+5)° = 180° (opposite angles sum up to 180°)

35+5x+5 = 180

40+5x = 180

5x= 180- 40

5x = 140

x = 28

therefore, the missing angle = (5x+5)°

= (5×28+5)= 140+5= 145°

Answer: $2400

Step-by-step explanation:

$2225.50 x 1.2% =  $26.71 + $2225.50 =  $2252.21  - Year 1

$2252.21 x 1.2% = $27.03 + $2252.21 =  $2279.23  - Year 2

$2279.23 x 1.2% = $27.35 + $2279.23 =  $2306.58  - Year 3

$2306.58 x 1.2% = $27.68 + $2334.26 =  $2334.26  - Year 4

$2334.26 x 1.2% = $28.01 + $2362.27 =   $2362.27  - Year 5

$2362.27 x 1.2% = $28.35 + $2362.27 =  $2390.62  - Year 6

$2390.62 x 1.2% = $28.69 + $2390.62 =  $2419.31  - Year 7

$2419.31         x 1.2% = $29.03 + $2419.31 =  $2448.34  - Year 8

Rounded to the nearest 100th = $2400

Answer:

48 (rounded to 10).....

Given:

Angle 6 = 25 degrees

To Find:

The value of Angle 7

Solution:

We know that,

the value of Angle 6 is equal to 25 Degrees

Since Angle 6 and Angle 7 together comprise of a Straight Line, this means that they are Supplementary Angles.

Therefore,

Angle 6 + Angle 7 = 180 degrees

This implies that,

25 degrees + Angle 7 = 180 degrees.     (since Angle 6 = 25 Degrees)  

Angle 7 = (180-25) degrees

Thus ,

Angle 7 = 155 degrees

Hence, Angle 7 is  155 degrees (Option 1)

Lamont should sample only registered voters to predict who will be elected mayor

A survey is a research method used for collecting data from a predefined group of respondents to gain information and insights into various topics

Since Lamont is trying to predict who will be elected, surveying people that are not registered to vote will not give him an accurate prediction.  If someone is not registered to vote, they cannot vote for any candidate.

To get more accurate results, Lamont should only sample people that are registered voters.

Answer:

Step-by-step explanation:

Let's start the sum as follows:

x³ = 8

X × X × X = 8

This means there are 3 number which after Multiplication gives answer 8.

If 2 is multtiplied 3 times it will give you 8

Thus the answer of x is 2

x = 2.

x^3 = -8

The cube root of 8 is 2 = 2 x 2 x 2 is 8.

But, the answer is negative, which means that the cube root of -8 must be -2.

-2 x -2 x -2 = -8

x = -2

Answer:

3 or 4, I am confused

Step-by-step explanation:

I'll assume that f(x) = x2 – 2x + 8 is meant to be f(x) = x^2 – 2x + 8

Find the value of f(x) for x = 2:

f(x) = x^2 – 2x + 8

f(2) = (2)^2 – 2*(2) + 8

f(2) = 4 - 4 + 8

f(2) = 8

=============

From the graph, we can find that g(2) = 11

The differece between g(2) and f(2) is thus:

   11 - 8 = 3

3 is not an option, so I wonder if the question is asking for the difference between the absolute maximum of g(x) and f(2).  If so, the maximum for g(x) is 12, at x = 3.  

This would lead to a difference of 12 - 8, or 4.  This is still not an option, so I'm confused.  Perhaps you can find my error and find the ciorrect answer, or at least one that appears in the options.

Answer:

50 minutes

Step-by-step explanation:

Given:

[tex]\bullet \ \ \text{Monday:} \ \dfrac{2}{3} \times \text{Hour}\\\\\bullet \ \text{Wednesday:} \ \dfrac{1}{2} \times \text{Hour}[/tex]

Since Emily only practiced on Monday and Wednesday, the sum of time on both days is the time Emily practiced on the piano for a week.

[tex]\implies \text{Monday + Wednesday = Total time practiced on piano for a week}[/tex]

Substitute the times in the equation

[tex]\implies (\dfrac{2}{3} \times \text{Hour}) + (\dfrac{1}{2} \times \text{Hour}) = \text{Total time practiced on piano for a week}[/tex]

Simplify the equation

[tex]\implies (\dfrac{2}{3} \times 60 \ \text{minutes}) + (\dfrac{1}{2} \times 60 \ \text{minutes}) = \text{Total time practiced on piano for a week}[/tex]

[tex]\implies (20 \ \text{minutes}) + (30 \ \text{minutes}) = \text{Total time practiced on piano for a week}[/tex]

[tex]\implies \boxed{50 \ \text{minutes} = \text{Total time practiced on piano for a week}}[/tex]

And , we have to find the height of cylinder .

We know that ,

Our solution starts from here :

[tex] \longmapsto \: \pi \: r {}^{2} h = 225\pi[/tex]

Step 1 : Cancelling π with π :

[tex] \longmapsto \: \cancel{\pi} \: r {}^{2} h = 225 \cancel{\pi}[/tex]

Step 2 : Substituting value of radius which is 5 cm in the formula :

[tex] \longmapsto \: (5) {}^{2} \times h = 225[/tex]

[tex] \longmapsto \: 25h = 225[/tex]

Step 3 : Transposing 25 to right hand side :

[tex] \longmapsto \: h = \frac{225}{25} [/tex]

Step 4 : Cancelling 225 by 25 :

The true statement for f(x)=b^x is the function is always decreasing function.

We have given,

f(x)=b^x where 0<b<1

Domain is all possible values of x for which any function is defined

We can select any values of x for which function

It will be defined for all real x

So, the domain is [tex](-\infty,\infty)[/tex]

The range is all possible values of y for which x is defined

we are given that b is positive

The value of the function will always be positive

So, the range is  [tex](0,\infty)[/tex]

y>0

The x-intercept:

Set f(x)=0 and then we can solve for x

f(x)=b^x=0

x is undefined

The x-intercept does not exist

Increasing or decreasing:

Since, 0<b<1

The b is a positive value less than 1

As we increase the value of, [tex]b^x[/tex] will keep decreasing

This is decreasing function
