Answer:

C) 19

Step-by-step explanation:

The two angles next to each other are complementary angles meaning they add up to 90°. We can use this information to solve for y:

3y + 2 + 31 = 90

3y + 33 = 90

3y = 57

y = 19

What is the solution of logx 729=3?

shusha [124]

Answer:

Solution

Step-by-step explanation:

Rewrite logx729= 3 is an exponential form using the definition of a logarithm. If x and b are positive real numbers and b≠1, then logb(x)= y is equivalent to b^y = x.

X^3 = 729

Take cube root on both side and we get

x= 3√729

now we firstly simplify the 3√729

Rewrite 729 as 9^3

x = 3√9^3

pull terms out from under the redical, assuming positive real numbers

x=9

verify each of the solution by substituting them into logx729=3 and solving.

x= 9

Esther cut a square paper vertically to make two rectangle pieces. Each rectangle had a perimeter of 63 inches.

Studentka2010 [4]

Answer:

Side of the square paper = 21 inches

Step-by-step explanation:

Let the square paper is having measure of each side = a inches

Esther cut this square piece into two pieces.

Let the other side of one rectangle piece = x inches

Perimeter of this piece = 2(a + x) inches

Similarly dimensions of the other rectangular piece will be = a inches × (a - x) inches

Perimeter of this piece = 2[a + (a - x)]

Since both the rectangular pieces have the same perimeter = 63

So, 2(a + x) = 2[a + (a - x)] = 63

2(a + x) = 2(2x - x)

a + x = 2a - x

2a - a = 2x

a = 2x

x = $\frac{a}{2}$

Therefore, Perimeter = 2(a + x) = 2(a + $\frac{a}{2}$ ) = 63

$2\times \frac{3a}{2}$ = 63

3a = 63

a = 21

Therefore, measure of the sides of the square is 21 inches.

Is 28.256 a positive or negative notation?

WARRIOR [948]

Answer:

To change a number from scientific notation to standard form, move the decimal point to the left (if the exponent of ten is a negative number), or to the right (if the exponent is positive). You should move the point as many times as the exponent indicates. Do not write the power of ten anymore.
