Solids X and Y are similar.
X has volume of 64 cm3
Y has volume of 729 cm3
The surface area of X is 208 cm2
Work out the surface area of Y.​

Answers

Answer 1

Answer: 2,369.25 cm3

Step-by-step explanation:

Hi, to answer this question we have to use proportions:

X has volume of 64 cm3 and s surface area of 208 cm2

The proportion is = volume / surface area = 64/208

Y has volume of 729 cm3

Volume / surface area = 729/ s (surface area of y)

64/208 = 729/ s

Solving for s:

s = 729 / (64/208)

s = 2,369.25 cm3

M < 7 is the answer because if m was equal to seven the equation would be 19 > 19 which cannot be correct so m must be less than 7

Option d. m>7 is the correct answer.

Given,

     2m+5>19

or, 2m+5+(-5)>19+(-5)      [adding both side with a negative number doesn't

                                           change the inequality sign]

or, 2m>14

or, (2m/2)>(14/2)             [also dividing both sides by a non-negative number     doesn't change the inequality sign]

or, m>7.

Hence, m>7 is the correct answer to the given question.

Meghan earns $20 for every 5 bracelets she makes. How many bracelets must she make to earn $140?

Answers

So this is a two step equation.
The first step would be to find out how many times 20 goes into 140.
140/20=8
So if she makes 5 bracelets for every 20 dollars she makes, and she made 20 dollars 8 time. She would’ve made 5 bracelets, 8 times.
So take 5 bracelets and multiply it by 8.
She needs to make 40 bracelets. :)
Meghan made 35 bracelets

Answers

An open circle is used to graph strict inequalities, which means the inequality does not include the value at the boundary. The inequalities that would have an open circle when graphed are:

x > 5.4

One-half less-than x

x > 0

All of the options that are just LESS THAN are open circled

if an inequality states less than OR equal to that means the circle will be closed when graphed

Answers

To solve you can use inverse operations.

Here are the steps to find the answer:

1. Write out the equation: -6(x-2)+3x= -3(x+3) +21

2. Distribute both sides: -6x+12+3x= -3x-9+21

3. Simplify both sides: -3x+12=-3x+12

4. This equation is true for all values, or infinity, because the equation is the same on both sides

The value of n is 6.22

Explanation: N is the number that you are trying to find and if N + 7.6 is equal to 13.82, an easy way to find N is by subtracting 7.6 from 13.82 (13.82-7.82=6.22)

Which of the following tables represent a proportional relationship?

Which of the following tables represent a proportional relationship?

Answers

Answer:

B.

Step-by-step explanation:

If you want to find a table with a proportional relationship, you are looking for one where the x-values and y-values increase at the same linear rate.

In Option A, the x-values increase steadily by 1 and then by 2, but the y-values jump around. The numbers are not proportional.

In Option B, every time an x-value is presented, the y-value is two times the value of x. So, this is a proportional relationship.

In Option C, it is true that for almost every time an x-value is presented, the y-value doubles the x-value, but when x is 0, y is 1. That is not a proportional relationship.

In Option D, it is the same thing as Option A.

So, your answer is Option B.

Hope this helps!

The answer is B hope it helped

ASAP : What is the y-coordinate of the center of the circle for the following circle equation? x2 + y2 - 10y + 18x = 2

Answers

Answer:

y = 5

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre ad r is the radius

Given

x² + y² - 10y + 18x = 2 ( Rearrange collecting x and y terms together )

x² + 18x + y² - 10y = 2

Using the method of completing the square

add ( half the coefficient of the x/ y term )² to both sides

x² + 2(9)x + 81 + y² + 2(- 5)y +25 = 2 + 81 + 25

(x + 9)² + (y - 5)² = 108 ← in standard form

with centre = (- 9, 5 )

The y- coordinate of the centre is therefore y = 5

34/9 as a mixed number

Answers

\(\dfrac{34}{9}\) as mixed number

Divide numerator by denominator:

\(34\div9=3R7\)

The 3 becomes a whole number and the remainder becomes the new numerator and the denominator stays the same.

\(\fbox{3$\dfrac{7}{9} $}\)

The mixed number representation of fraction 34/9 is \(3\frac{7}{9}\).

To express the fraction 34/9 as a mixed number.

we need to find the whole number part and the fractional part.

Divide the numerator (34) by the denominator (9):

34 ÷ 9

= 3 remainder 7

The quotient 3 represents the whole number part, and the remainder 7 represents the fractional part.

Therefore, the mixed number representation of 34/9 is  \(3\frac{7}{9}\).
