!PLEASE HELP, THANK YOU!Which 3-D Figure Matches The Surface Area Formula? Figure A Figure B Figure C

Answers

Answer 1

Answer:

D

Step-by-step explanation:

you mean the formula is 4×pi×r² (not 4×pi/r²), right ?

then the correct answer is the sphere (ball).

the surface area of a cylinder is

top and bottom circle area = pi×r² each = 2×pi×r² both

and the mantle is 2×pi×r×height

the surface area of a block has nothing to do with pi.

it is the sum of 6 rectangles.

the surface area of a cone is

A = πr(r + sqrt(h² + r²))

again, also depending on "hight"

The area of a rectangle is 54 square meters. The width is 9 meters long.

Answers

Answer:

A) [tex]9 *l=54[/tex]

Step-by-step explanation:

The area of a rectangle is w*l=A, where w is the width and l is the length.

In this question, we are given 2 of the variables. We are told that the width is 9 and the area is 54. So, to find the equation that represents this situation, simply plug in the values.

This gives [tex]9 *l=54[/tex].

Then, if needed we can find the length of the rectangle. Through the division property of equality, we know that dividing both sides of the equation maintains the equality of the equation. So, we can divide both sides by 9 to isolate the variable.

This means that [tex]l=6[/tex].

Answers

Answer:

495cm

Step-by-step explanation:

so for a second forget about the already 12 meters. Multiply 15 by the amount of months, in this case 40 so 12x40= 480. Then add the 15, so its 495cm tall

What is the percentage tax charged if a calculator which cost $4000 is sold for $5000 after tax ?

Answers

Answer:

25%

Step-by-step explanation:

find the differences between original price $4000 and the altered price $5000.

$5000 - $4000 = $1000

to find the tax percent charged, take the difference price, divide by the original price and multiply with 100, ( to find percentage, it is a must to multiply with 100 ).

1000/4000 x 100

= 25%

so you will get 25 %

Given the following exponential function, identify whether the change represents growth or decay, and determine the percentage rate of increase or decrease. y=5800(0.806)^x

Answers

Using exponential function concepts, it is found that it represents a decay of 19.4%.

What is an exponential function?

A decaying exponential function is modeled by:

[tex]A(t) = A(0)(1 - r)^t[/tex]

In which:

A(0) is the initial value.r is the decay rate, as a decimal.

In this problem, the function is:

[tex]A(x) = 5800(0.806)^x[/tex]

Since the rate of change is less than 1, it is a decay.

Then:

1 - r = 0.806.

r = 1 - 0.806 = 0.194.

The function represents a decay of 19.4%.

What is the domain of the function y = l n (StartFraction negative x 3 Over 2 EndFraction).

Answers

The domain of the provide function where the function is defined is x less than the number three.

What is the domain of the function?

Domain of a function is the set of all the possible input values which are valid for that function.

The function given in the problem is,

[tex]y=\ln\left(\dfrac{-x+3}{1}\right)[/tex]

The above function is the function of logarithm. For the logarithmic function, it is defined for all the real numbers except 0.

Thus, the function should be greater than zero as,

[tex]\left(\dfrac{-x+3}{1}\right) > 0\\(-x+3) > 0\\-x > -3[/tex]

Change the sign of both side, by changing the inequality,

[tex]x < 3[/tex]

Thus, the domain of the provide function where the function is defined is x less than the number three.

Our goal is to round it so we only have an integer part using the following rules:

If the first digit in the fractional part of 13.62 is less than 5 then we simply remove the fractional part to get the answer.

If the first digit in the fractional part of 13.62 is 5 or above, then we add 1 to the integer part and remove the fractional part to get the answer.

Leila purchased a snack-size roll of candy tarts, and found that only 1/7 of them were grape-flavored. Suppose Leila later
buys a king-size roll of candy tarts that contains 40 pieces. How many of that roll can she expect to be grape-flavored?

HELP PLEASE!!!!!

Answers

Answer:

6 candy tarts

Step-by-step explanation:

Based on Leila's observations, we would expect all boxes of candy tarts to have 1/7 grape-flavoured ones. If we have a box of 40, we can find the expected number of grape flavoured nady tarts by multiplying 40 and 1/7.

40 × 1/7 = 5.714285714

You can round this to 6 candy tarts

chloe wants to ride her bicycle 34.1 miles this week. She has already ridden 14 miles if she rides for 3 more days, write and solve an equation which can be used to determin m, the avergae number of miles she would have to ride each day to meet her goal.

Answers

Step-by-step explanation:

I guess the meaning is that after 3 more days the week will be over, and she has to reach her goal by then.

x = the average number of miles to ride each of the 3 days

x = (34.1 - 14)/3

the solution is

x = 20.1/3 = 6.7 miles

Function 1 and the slope is
-4/7

B.
Function 1 and the slope is
-4

C.
Function 2 and the slope is
-3/5

D.
Function 2 and the slope is
2

Answers

Answer:  Choice A

Function 1 and the slope is -4/7

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

Explanation:

The slope of y = mx+b is m, which is the number to the left of x.

For function 1

y = (-4/7)x - 4

the slope here is m = -4/7 = -0.57 approximately

Let's use the slope formula to find the slope of function 2 given by the table of values.

Pick any two rows from that table. I'll pick the first two rows.

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

m = (0.8 - 2)/(2 - 0)

m = -0.60

Comparing -0.57 and -0.60, we see that -0.57 is closer to zero on the number line. Meaning that function 1 has the less steep slope (i.e. more shallow slope). The further you go away from zero on the number line, in either direction, the slope will get steeper.
