Answer:

b. 156

Step-by-step explanation:

A "perfect square" is the product of an integer that is being multiplied by itself.

Choice a, 625, is a perfect square because it is the product of 25 multiplied by itself.

Choice b, 156, is not a perfect square because you cannot find any integer that can be multiplied by itself that will result in 156 as a product. Therefore, this is the correct answer.

Choice c, 196, is a perfect square because it is the product of 14 multiplied by itself.

Answer:

y = -1/3x

Step-by-step explanation:

The slope of that are perpendicular lines are negative opposites of each other. If a line has a slope of 3, then a line perpendicular to it will have a slope of (-(1/3)).

Use the equation of a line in point-slope form to solve this;

y = mx + b

where "m" is the slope and "b" is the y-intercept.

Substitute the slope in;

y = (-1/3)x + b

Since it passes through the origin, then it has no y-intercept, therefore the equation of the line is;

y = -1/3x

Answer:

8posters are created

Step-by-step explanation:

Given the function that represents the total number of posters expressed as

f(t)= 5t+3

The total posters every hour occur at t = 1hr

Substitute into the equation

f(1) = 5(1)+3

f(1) = 5+3

f(1) = 8

Hence the function f represents the fact that every hour, 8posters are being created

Answer:

378

Step-by-step explanation:

Remark

This is a question that all investors in stocks should be aware off. It does not come back to 450 dollars.

Step One

Find out the price of the discounted camera.

40% reduction price =  450 - (40/100)*450

40% reduction price = 450 - 180 = 270

Step Two

Now add 40% onto the new price.

New price = Reduced price + 40% of reduced price

New Price = 270 + 40%* 270

New Price = 270 + 108

New Price = 378

Remark

The reason stock investors should be aware of this is that if you take a 40% loss on a stock it takes more than a 40% gain to make the price of your stock loss back.

Answer:

Miko found an incorrect quotient and checked her work using multiplication incorrectly.

Step-by-step explanation:

The given expression is

[tex]\dfrac{5}{\dfrac{5}{3}}[/tex]

Applying the reciprocal rule we get

[tex]5\times \dfrac{3}{5}=5[/tex]

What Miko did was

[tex]3\times \dfrac{5}{3}=\dfrac{3}{1}\times\dfrac{5}{3}=\dfrac{15}{3}\ \text{or}\ 5[/tex]

So, Miko took the wrong values of the quotients and applied multiplication incorrectly.

Hence, Miko found an incorrect quotient and checked her work using multiplication incorrectly.

Determine how far he walked in one loop

This question is incomplete, as the playground diagram and dimensions are missing. However, I'll answer on a general terms.

What this question requires is to calculate the perimeter of the playground.

Assume that the playground is rectangular and the dimensions are: 2  meters by 3 meters.

The distance walked will be calculated using the following perimeter formula.

[tex]Distance = 2(2m + 3m)[/tex]

[tex]Distance = 2(5m)[/tex]

[tex]Distance = 10m[/tex]

If it is a square with 5m as the length of one of its side, the distance would be:

[tex]Distance = 4 * 5m[/tex]

[tex]Distance = 20m[/tex]

So basically, all you need to do is calculate the perimeter of the playground.

Answer:

The measure of the complement =

= 80°

The measure of the supplement=

= 170°

Step-by-step explanation:

Let

90-x equal the degree measure of its complement

180-x equal the degree measure of its supplement.

We are told in the question that: the supplement of a given angle is 10 degrees more than twice its complement.

Hence, the Equation is;

(180 - x) = 10° + 2(90 - x)

180 - x = 10 + 180 - 2x

Collect like terms

-x + 2x = 10 + 180 - 180

x = 10°

Hence,

The measure of the complement =

90 - x

= 90 - 10

= 80°

The measure of the supplement=

180 - x

= 180 - 10

= 170°

Answer:

Yew, he has enough money to buy the guitar in september.

Step-by-step explanation:

300*0.75=225        300+225=525

650*0.35=195            650-195=455

sales tax:    455*0.05=22.75          455+22.75=477.75

Yes , Arnold have enough savings to buy the guitar

Savings amount of Arnold is $ 525 and the price of the guitar is $ 477.75

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the original price of the guitar be = $ 650

Let the initial savings of Arnold be = $ 300

Now , Arnold saved 75 % more than what he actually had

And , the equation will be

So , the new savings of Arnold is = 300 + ( 75/100 ) x 300

The new savings of Arnold is = 300 + ( 300 x 0.75 )

The new savings of Arnold is = 300 + 225

The new savings of Arnold is = $ 525

Now , the price of the guitar is discounted by = 30 %

And , the equation will be

So , the new price of the guitar after discount is = 650 - ( 30/100 ) x 650

The new price of the guitar after discount is = 650 - ( 650 x 0.30 )

The new price of the guitar after discount is = 650 - 195

The new price of the guitar after discount is = $ 455

Now , A sales tax of 5 % is priced on the guitar

And , the equation will be

So , the sale price of the guitar is = 455 + ( 5/100 ) x 455

The sale price of the guitar is = 455 + 22.75

The sale price of the guitar is = $ 477.75

Now , the new savings of Arnold is greater than the sale price of the guitar

$ 525 > $ 477.75

Therefore , Arnold have enough savings to buy the guitar

Hence , Yes , Arnold have enough savings to buy the guitar

Savings amount of Arnold is $ 525 and the price of the guitar is $ 477.75

Step-by-step explanation:

Answer:

The length of SO is 46 units

Step-by-step explanation:

In a parallelogram, diagonals bisect each other, which means meet each other in their mid-point

∵ SNOW is a parallelogram

∵ SO and NW are diagonals

∵ SO ∩ NW at point D

→ That means D is the mid-point of SO and NW

∴ D is the mid-point of SO and NW

∵ D is the mid-point of SO

→ That means D divide SO into two equal parts SD and DO

∴ SD = DO

∵ SD = 9x + 5

∵ DO = 13x - 3

→ Equate them

∴ 13x - 3 = 9x + 5

→ Subtract 9x from both sides

∵ 13x - 9x - 3 = 9x - 9x + 5

∴ 4x - 3 = 5

→ Add 3 to both sides

∵ 4x - 3 + 3 = 5 + 3

∴ 4x = 8

→ Divide both sides by 4

∴ x = 2

→ To find the length of SO substitute the value os x in SD and DO

∵ SO = SD + DO

∵ SD = 9(2) + 5 = 18 + 5 = 23

∵ DO = 13(2) - 3 = 26 - 3 = 23

∴ SO = 23 + 23 = 46

∴ The length of SO is 46 units
