b. 50
c. 5
d. 0.5

Answers

Answer 1

Answer: Answer=C

The first step in estimating is to round the numbers into simpler numbers so that we can easily do the math in our head...

312.21 becomes 300

59.113 becomes 60

300÷60=5

Answer=C

Answer 2

Answer: Answer=C

312.21 would be 300

59.113 would be 60

300÷60=5
Im pretty sure that is right IDK im in Middle School

Let n = 2.5. what is the value of 2n(6n-3)+4n?

Answers

$n = 2.5, \ \n\n\ 2n(6n-3)+4n = 12n^2 - 6n +4n =12n^2-2n\n \n12n^2-2n=12 *(2.5)^2-2*2.5=12*6.25-5=75-5=70$

$2n(6n-3)+4n$

substitute $n=2.5$

$2*2.5(6*2.5-3)+4*2.5=5(15-3)+10=60+10=70$

do you think making a table is the best way to find the total area of the rooms given in the example is there another problem solving strategy you think would work just as well or better describe the alternate method and why you think it works

Answers

Well,

First, we'd need to see what the problem is. If it's an illustration with all of the dimensions of the rooms labeled, you can just write the area inside each room and then make a list of the values. From there you can just add them up. So making a table is just a more formal way of organizing your data. The grids really do not offer much help in adding up the areas.

PLEASE HELP ME I CANT DO IT IVE TRIED SO MUCHThe formula C=5/9(F-32) expresses the relationship between Fahrenheit temperature F, and Celsius Temperature C. Use the formula to convert the given Fahrenheit to its equivalent temperature in the Celsius scale.

4 degrees F= Degree C

Answers

Answer:

-15.556°C.

Step-by-step explanation:

To convert the given Fahrenheit temperature to its equivalent temperature in the Celsius scale, we can use the formula:

C = (F - 32) / 1.8

Given that the Fahrenheit temperature is 4°F, we can substitute this value into the formula:

C = (4 - 32) / 1.8

Simplifying the equation:

C = (-28) / 1.8

Calculating the value:

C = -15.556°C

bellow.

Step-by-step explanation:

To convert 4 degrees Fahrenheit to its equivalent temperature in Celsius, we can use the given formula:

C = (5/9)(F - 32)

Let's substitute the Fahrenheit value of 4 into the formula:

C = (5/9)(4 - 32)

Now, let's simplify the equation step by step:

1. Subtract 32 from 4:

C = (5/9)(-28)

2. Multiply -28 by 5/9:

C = (-140/9)

Therefore, 4 degrees Fahrenheit is equivalent to approximately -15.6 degrees Celsius.

The The graph of g(x) is the result of translating the graph of f(x) = 3x six units to the right. What is the equation of g(x)?g(x) = 3x – 6
g(x) = 3x + 6
g(x) = 3x – 6
g(x) = 3x + 6
Mark this and return

Answers

Translation the graph of the function $y=f(x)$ a units to the right gives you the function $y=f(x-a).$

If the graph of the function $f(x)=3^x$ is translated 6 units to the right, then the function becomes

$g(x)=f(x-6)=3^(x-6).$

The perimeter of a square garden is to be at least 30 feet but not more than 64 feet. Find all possible values for the length of its sides.

Answers

Answer:

$7.5\leq x\leq 16$

Step-by-step explanation:

Let x be the length of each side of square.

Since the perimeter of the square is 4 times the length of each side, so perimeter of our given circle will be 4x.

We have been given that the perimeter of a square garden is to be at least 30 feet but not more than 64 feet.

This means the perimeter of the garden should we greater than or equal to 30 feet and less than or equal to 64 feet.

We can represent this information in an equation as:

$30\leq 4x\leq64$

Let us divide our inequality by 4 to solve for x.

$(30)/(4)\leq (4x)/(4)\leq(64)/(4)$

$7.5\leq x\leq 16$

We can represent our answer in interval notation as: $[7.5,16]$

Therefore, the length of the square's side can be any number between 7.5 feet and 16 feet including both 7.5 and 16 as well.

$4x \in <30.64>/:4 \n x \in <7.5,16>$

The curved surface of cylinder is 484 cm^2 and height is 5.5 cm. Find its radius.

Answers

Answer:

r=14cm

Step-by-step explanation:

Curved Surface area of a cylinder=484cm²

Height=5.5cm

r=?

Curved Surface Area=2πrh

484=2×3.142×r×5.5

484=34.56r

r=484/34.56

r=14cm

Answer:

radius= 14

Step-by-step explanation:

curved surface area of cylinder = 484

height = 5.5

C.S.A = 2πrh

or, 484 = 2×22/7×r×5.5

or, 484×7 = 2×22/7×5.5×r

or, 3388 = 242×r

or, 3388/242 = r

or, 14 = r
