For what value of y does 125 = (StartFraction 1 Over 25 EndFraction) Superscript y minus 1? Negative five-halves –2 –1 Negative one-half.

Answers

Answer 1

Answer:

D. -1/2

Step-by-step explanation:

First to rewrite the equation in numbers

[tex]125=\frac{1}{25}^{y-1}[/tex]

First, we need to find what exponent would get 1/25 to 125.

[tex]\frac{1}{25}^{y}=125[/tex]

Sense 1/25 is a fraction we must use a negative exponent to make it a whole number. We can just find what exponent would get 25 to 125 then make it negative. 1 wouldn't be enough and 2 would be too much so y is between 1 and 2 into negative is between -1 and -2. Sense the original equation has (y-1) the only option you can subtract 1 from to get between -1 and -2 is -1/2 which would give -1 1/2.

Answer 2

Keep it simple: D or -1/2

The condition of two congruent angles in each triangle, can be used to

show that the two triangles are similar.

Response:

Part 1: The two triangles are similar by AA similarity postulatePart 2: AC = 22.5 inches, AB = 30 inches

Which condition of similarity makes the two triangles similar?

Part 1:

A two column proof is presented as follows;

Statement [tex]{}[/tex]                                    Reason

1. ∠D ≅ ∠A [tex]{}[/tex]                                   1. Given

2. ∠DCE ≅ ∠ACB [tex]{}[/tex]                        2. Vertical angle theorem

3. ΔCDE ~ ΔCAB [tex]{}[/tex]                         3. AA similarity postulate

Angle-Angle, AA, similarity postulate states that if two angles in one

triangle are congruent to two angles in a second triangles, then the two

triangles are similar.

Part 2:

From part 1, we have;

ΔCDE is similar to ΔCAB (ΔCDE ~ ΔCAB)

The ratio of corresponding sides of similar triangles are equal, which

gives;

[tex]\dfrac{\overline{CD}}{\overline{AC}} = \mathbf{\dfrac{\overline{CE}}{\overline{CB}}}[/tex]

Which gives;

[tex]\dfrac{12}{\overline{AC}} = \mathbf{\dfrac{8}{15}}[/tex]

[tex]\overline{AC}} = \dfrac{15}{8} \times 12 = \mathbf{22.5}[/tex]

AC = 22.5 inches

Similarly, we have;

[tex]\dfrac{\overline{DE}}{\overline{AB}} = \mathbf{\dfrac{\overline{CE}}{\overline{CB}}}[/tex]

Which gives;

[tex]\dfrac{16}{\overline{AB}} = \dfrac{8}{15}[/tex]

[tex]{\overline{AB}} = \dfrac{15}{8} \times 16 = \mathbf{30}[/tex]

AB - 30 inches

PLEASE HELP ME IF YOU CAN AS SOON AS POSSIBLE. THANK YOU ​

Answers

(220,10)

Step-by-step explanation:

This reminds me of when I was in middle school

Answer:

(110, 135)

Step-by-step explanation:

From the coordinates given, the shape of the ceiling is a rectangle.

Width = difference in x-coordinates = 220 - 0 = 220

Length = difference in y-coordinates = 260 - 10 = 250

To find the center of the ceiling, we need to find the centroid (center-point) of the rectangle.

x-coordinate = Half of the width + smallest x-coordinate= (220 ÷ 2) + 0 = 110

y-coordinate = Half of the length + smallest y-coordinate = (250 ÷ 2) + 10 = 135

Therefore, the center of the ceiling is at (110, 135)

Answers

Expression giving the result of the perimeter of rectangle A and demonstrating  the closure property is given by: Option A: [tex]10x + 4[/tex] ; the answer is a polynomial

What is the closure property of a polynomial for addition operation?

Closure property keeps the result in the same set.

If two polynomials [tex]f(x)[/tex] and [tex]g(x)[/tex] are there.

Then, [tex]f(x) + g(x) = h(x)[/tex]

where [tex]h(x)[/tex] is also a polynomial.

The result of the addition of two polynomials is also a polynomial. This property of polynomial for addition operation is called closure property of a polynomial for addition operation

For the given case, we have:

Length of the rectangle = [tex]3x + 5[/tex]Width of the rectangle = [tex]2x -3[/tex]

Perimeter of a rectangle with width W and length L = 2(L + W)

And using that formula, the perimeter of the considered rectangle is evaluated as:

[tex]P = 2(3x + 5 + 2x - 3)\\P = 2((3+2)x + 2) = 2(5x + 2)\\\\P = 10x + 4[/tex]

Thus, expression giving the result of the perimeter of rectangle A and demonstrating  the closure property is given by: Option A: [tex]10x + 4[/tex] ; the answer is a polynomial

How to find the range of a set of data values?

Range = Maximum value of the data set - Minimum value of the data set.

For the given sets, we get their range as:

Set 1: 48, 47, 34, 37, 11, 39

Maximum value = 48, minimum value = 11

Range of the data set = Maximum value - minimum value = 48-11 = 37

Set 2: 42, 47, 44, 40, 41, 49, 48, 45, 43

Maximum value = 49, minimum value = 40

Range of the data set = Maximum value - minimum value = 49 - 40 = 9

Set 3: 85, 98, 31, 96, 49, 77, 82

Maximum value = 96, minimum value = 31

Range of the data set = Maximum value - minimum value = 96-31=65

Set 4:  112, 114, 116, 175, 115, 134, 117

Maximum value = 175, minimum value = 112

Grandma baked 1.5 times as many pancakes as waffles. After she baked 45 more waffles, and her grandchildren ate 12 pancakes, there were 17 more waffles than pancakes. How many waffles were there initially?

PLS HELP YOU WILL GET BRAINLY!!!

Answers

Step-by-step explanation:

let x represent the no of pancakes,

she baked 1.5 times pancakes more than waffles,

so from this, no of pancakes = 1.5x,

then she baked more 45 waffles,

no of waffles = (x +45)

so you had 1.5x pancakes and the children ate 12 out of them. the no of pancakes has then been reduced by 12.

thus, no of pancakes = ( 1.5x -12 )

now they see that they have 17 more waffles that pancakes left. this means that :

no of waffles - no of pancakes = 17

(x+45) - (1.5x - 12) = 17

x - 1.5x + 45 + 12 = 17

x = -50 / -0.5

x = 100

hence, there were 100 waffles initially.
