Students need at least 75 hours of volunteer service to meet their graduation requirement. Samir has already completed 48 hours. Write and solve an inequality to determine how many more hours he needs to complete.

Answers

R is the amount of hours remaining to complete the requirement

R + 48 ≥ 75

Subtract 48 from both sides of the equation:

R ≥ 27

He has to complete an amount of hours greater than or equal to 27
a variable, so I will use the variable X then your hours completed which is 48, so it looks like  (X + 48) now we have to compare it to how many hours he needs to do. Because it says at least we use the sign , Now the equation is X + 48  75.
X + 48   75

I asked this question a couple of minutes ago and I feel like it isn't being understood completely so I edited the question to specify a little bit and posting it again. I am hoping you all understand it now and give me the best results. A huge thank you to all who attempts to answer!

Answers

Answer:

Look at explanation plz

Step-by-step explanation:

1) so we know that b cannot be anything lower than 0

So let’s substitute -7 in place of c:

x^2+bx-7

Factors of -7: 7,-1. -7,1

Only factor pair that Will not result in a negative or 0: 7,-1

Integers for B: 7,-1

Let’s do the same with number 2:

X^2+bx-3

Factors of -3: 3,-1. -3,1

Only factor pair that will not result in a negative or 0: 3,-1

Integers for B:3,-1

3) you know the drill:

6= 3,2 -3,-2. 6,1 -6,-1

Positive integers of 6: 3,2 or 6,1

Values for B: 3,2 OR 6,1 your choice

4) 12= 12,1. -1,-12. 4,3. -4,-3 6,2. -6,-2

Values for B: 12,1 or 4,3 or 6,2
I think the answer is 3. C= -3 and integer 2

36,204+40,918 estimate then find the sum

Answers

Estimated guess 77,000 actual sum 36,204 + 40,918 = 77,112
First you need to round the numbers:

36,204 = 36,000
40,918 = 41,000

Now that the numbers are rounded it is easy to add them:

36,000 + 41,000 = 77,000

Hope this helps :)

Dmitri wants to cover the top and sides of the box shown with glass tiles that are 5mm square. How many tiles does he need? ( The length is 15cm, the width is 20cm and the height is 9cm).

Answers

Answer:

372

Step-by-step explanation:

We are given that the dimensions of the box are,

Length = 15 cm, Width = 20 cm and Height = 9 cm.

We know that the box represents a cuboid.

Since, surface area of a cuboid = L×W + 2×L×H + 2×W×H

Thus, the surface area of the box = 15×20 + 2×15×9 + 2×20×9

i.e. Surface area = 300 + 270 + 360

i.e. Surface area = 930.

Thus, the surface area of the box is 930 cm² i.e. 9300 mm².

Further, the sides of the tiles are 5 mm and the tile represents a square.

So, the surface area of the tile = 5 × 5 = 25 mm².

This gives us that,

Number of tiles required to cover the box = (9300)/(25) = 372.

Hence, Dmitri requires 372 tiles to cover the box.
The Surface Area = lw + 2lh + 2wh;
The Surface Area = 15*20 + 2*15*9 + 2*20*9;
The Surface Area = 300 + 270 + 360;
The Surface Area = 570 + 360;
The Surface Area = 930cm^2;
The surface of glass tile is 5 × 5 = 25 cm^2;
Then, 930 ÷ 25 = 37.2;
He need 38 tiles to cover the top and sides of the box shown.

Describe how the graph of g(x) is related to the parent function f(x). f(x) = 5x
g(x) = 5x + 3

The options are
A)Adding 3 to the function translates the parent graph 3 units up.

B)Adding 3 to the function translates the parent graph 3 units down.

C)Adding 3 to the function translates the parent graph 3 units to the left.

D)Adding 3 to the function translates the parent graph 3 units to the right.

Answers

Answer:

Step-by-step explanation:

There are two functions f(x) = 5x and g(x) = 5x + 3

This parent function f(x) has been translated to form a new function g(x) = 5x + 3

These linear functions can be represented by two lines y = 5x and y' = 5x' + 3

So when we shift line y = 5x by 3 units up on the y-axis then a new graph of

y = 5x + 3 will be formed.

Therefore, Option A is the answer.

Answer:

A

Step-by-step explanation:

we have g(x) = 5x+3  

we know that 5x=f(x)

so g(x)=f(x)+3  

thus g(x) is obtained by adding 3 units to f(x)  

that's means the graph of g is obtained by translating the parent function f by 3 units up
