Answer:

The percentage increase in Spencer’s height is 125 %

Solution:

[tex]\begin{array}{l}{\text { Percentage increase }=\frac{\text { change in height }}{\text { initial height }} \times 100 \%} \\\\ {\text { percentage increase }=\frac{\text { increased height - initial height }}{\text { initial height }} \times 100 \%}\end{array}[/tex]

Initial height of spencer = 28 inches  

Increased height of spencer = 5 feet 3 inches  

= 5 feet + 3 inches  

(5 feet = 5 ×12=60 inches)

= 60  + 3

 [tex]\begin{array}{l}{\text { Increased height }=63 \text { inches }} \\ {\text { Percentage increase }=\frac{63-28}{28} \times 100 \%} \\\\ {=\frac{35}{28} \times 100 \%} \\\\ {=1.25 \times 100 \%} \\ {\text { percentage increase in height of spencer }=125 \%}\end{array}[/tex]

Answer: 25

Step-by-step explanation:

Since the exponents have the same denominator, you multiply the coefficients. In this case you multiply 5 times 5.

In the provided list, 26 and 0.9 are rational numbers. The number 5.737737773... and 45 squared (meant as the square root of 45) are irrational numbers.

In the mentioned list, the number 26 and the fraction 0.9 are rational numbers. A rational number can be expressed as a fraction where both the numerator and the denominator are integers (the denominator cannot be zero), and these numbers satisfy this condition. Examples of rational numbers include integers, fractional numbers, and decimals that terminate or repeat.

The number 5.737737773... and 45 squared (assuming it refers to the square root of 45) are irrational numbers. An irrational number is a number that cannot be expressed as a simple fraction. In the case of 5.737737773..., it seems to be a repeating decimal but the pattern is broken which makes it irrational. The square root of 45 is also irrational because it does not produce a simple fraction and its decimal form does not terminate or repeat.

Answer: a = 17/2  and b =1/2 and c = 6

Step-by-step explanation:

the system is :  a+b=9...........(1)

                        2b+2c=13 .......(2)

                        2a-c=11 ...........(3)

by (1) and (2) calculate : a and b

by (3) : 2a = 11 +c

so : a = (11+c)/2.....( *)

by (2) : 2b = 13 -2c

so : b =(13-2c)/2......(**)

put the value for a and b by (*) and (**) in (1) :

(11+c)/2. + (13-2c)/2 = 9

(11+c +13-2c)/2 = 9

24-c =18

c = 24-18

c = 6

put this value in (*) and (**)

a = (11+6)/2

a = 17/2

b = (13-12)/2

b =1/2

Answer:

Step-by-step explanation:

Sandra raised 15 dollars.

Nita raised 45

45 divided by 15 is 3

3 * 15 = 45

Final answer:

To find out how many times more money Nita raised compared to Sandra, divide Nita's amount ($45) by Sandra's amount ($15) to get a factor of 3. Thus, Nita raised three times as much money as Sandra.

Explanation:

The question asks us to calculate how many times more money Nita raised compared to Sandra. Since Sandra raised $15 and Nita raised $45, we can find the multiplicative factor by dividing the amount Nita raised by the amount Sandra raised.

To find out how many times the money raised by Nita compares to that of Sandra, we can use the formula:

Multiplier = Nita's Amount / Sandra's Amount

Multiplier = $45 / $15

Multiplier = 3

So, Nita raised three times as much money as Sandra did for the PTA.

The algebraic expression 4n-5 translates verbally to 'four times a number minus five.'

To translate the algebraic expression 4n-5 into a verbal statement, consider the components of the expression. The '4n' part indicates four times a number 'n', and '-5' signifies that five is subtracted from the product of four and the number. Thus, the verbal statement of the expression is 'four times a number minus five.'

The complete question is:Translate 4n-5 To verbal statement

|2x + 3| - 4 = 4

Then, add 4 more to each side.

|2x + 3| = 8

Subtract 3 from each side.

Answer:

Step-by-step explanation:

Y=2

Reflection of a rectangle over the x-axis (y = 0) will generally cause it to map onto itself. The other given lines (y = 2, y = x, and y = 2x) will not typically have this result, unless the rectangle is specifically located on the plane.

In geometry, a shape maps onto itself under reflection when it is reflected over a line that bisects it symmetrically. With a rectangle, this can occur when it is reflected over the x-axis or y-axis, assuming the rectangle's sides are parallel to the axes. From the given options, only y = 0 (x-axis) could create this type of reflection.

Reflection over the line y = 0 will leave a rectangle in the same position if its height is evenly distributed above and below the x-axis. For lines like y = 2, y = x, and y = 2x, they would not bisect a rectangle symmetrically unless the rectangle is specifically positioned, so they will not generally result in the rectangle mapping onto itself.

Answer:

f(- 2) = 1

Step-by-step explanation:

f(- 2) means what is the value of f(x) when x = - 2

From the table we can see that when x = - 2 f(x) = 1

Hence

f(- 2) = 1

Answer:

f(-2) = 1

Step-by-step explanation:

Actually, you need to know how to use this table to find the value of the function defined by the table when x = -2.  

Look in the first column of the table for x = -2.  When x = -2, f(x) = 1.  This is the desired result ("What is f(-2)?")

Answer:

see explanation

Step-by-step explanation:

Using the midpoint formula to equate the x and y coordinates of the endpoints to the x and y coordinates of the midpoint, that is

(6)

let ( x, y ) be the coordinates of the required endpoint, then

x → [tex]\frac{x+6}{2}[/tex] = 2 ( multiply both sides by 2 )

  x + 6 = 4 ( subtract 6 from both sides )

x = - 2 and

y → [tex]\frac{y+2}{2}[/tex] = 0 , thus

y + 2 = 0 ( subtract 2 from both sides )

y = - 2

Coordinates of the other endpoint = (- 2, - 2)

(7)

x → [tex]\frac{x-4}{2}[/tex] = - 1 ( multiply both sides by 2 )

x - 4 = - 2 ( add 4 to both sides )

x = 2 and

y→ [tex]\frac{y+3}{2}[/tex] = - 1 ( multiply both sides by 2 )

y + 3 = - 2 ( subtract 3 from both sides )

y = - 5

Coordinates of the other endpoint = (2, - 5)

(8)

x → [tex]\frac{x+7}{2}[/tex] = 2 ( multiply both sides by 2 )

x + 7 = 4 ( subtract 7 from both sides )

x = - 3 and

y → [tex]\frac{y+3}{2}[/tex] = 1 ( multiply both sides by 2 )

y + 3 = 2 ( subtract 3 from both sides )

y = - 1

Coordinates of the other endpoint = (- 3, - 1)

Answer: C/2a = r

Done.

Step-by-step explanation: To write a percent as a fraction in lowest terms, remember that a percent is a ratio that compares a number to 100. In this example, 88% can be written as the ratio 88 to 100 or 88/100. Notice however that 88/100 is not in lowest terms so we need to divide both the numerator and denominator by 4 to get 22/25.

Therefore, 88% can be written as the fraction 22/25.

Step-by-step explanation: To write a percent as a decimal, first remember that a percent is a ratio that compares a number to 100. We can think of 88% as the ratio 88 to 100 or 88 divided by 100. Remember that dividing by 100 moves the decimal point two places to the left so 88 divided by 100 would move the decimal point two places to the left which would give us .88 or 0.88.

Therefore, 88% can be written as the decimal 0.82.

To solve this problem, first let x=0.933333(repeating). Then, you want to multiply both sides by 10 to get 10x = 9.33333 (repeating). Next, take equation 2 and minus equation 1 from it giving you 9x = 8.4. Finally, multiply both sides by 10 and you will get 90x = 84. Divide both sides by 90 giving x=84/90. Answer is 84/90. 84/90 can reduce to 14/15.

The given ratio problem can be solved by converting the ratio to an algebraic equation and solving that equation. The total of deer and hunters on the ranch is 629 deer and 111 hunters.

The given ratio is of deer to hunters is 17:3, and their total sum is given as 740. We solve such problems by converting ratio to equation i.e., 17x + 3x = 740, where 'x' is a constant multiplier.

Adding 17x and 3x gives us 20x = 740. By dividing both sides by 20, we calculate the value of 'x' which is 37.

Substitute the value of 'x' in 17x and 3x, we get the number of deer and hunters as 629 and 111 respectively.
