9. A pyramid has a square base with an area
of 144 ft.2 What is the perimeter of the base
of the pyramid?

Answer:

Temperature of the water

Step-by-step explanation:

In every study, there must be a dependent variable and an independent variable. The effect of the independent variable on the dependent variable is monitored by carefully manipulating the independent variable and observing the response it produces on the dependent variable.

In this study, the independent variable is the temperature of the water while the dependent variable is plant growth. The various temperatures of the water used to water the plant will after its growth.

Answer:

Option D. 2x⁷ - 12x⁶ + 10x⁵

Step-by-step explanation:

From the question given:

Length (L) = 2x²

Width (w) = x³

Height (h) = x² - 6x + 5

Volume (V) =?

Volume (V) = length (L) x width (w) x height (h)

V = L x w x h

V = 2x² × x³ × x² - 6x + 5

V = (2x²) (x³) (x² - 6x + 5)

V = (2x⁵) (x² - 6x + 5)

Clear bracket

V = 2x⁷ - 12x⁶ + 10x⁵

Therefore, the volume of the cube is 2x⁷ - 12x⁶ + 10x⁵

Step-by-step explanation:

Darren has 84 DIMES and 144 PENNIES:

the ratio of dimes to penny=84/144=7/12

12 is GCF : 84/12=7, 144/12=12

Eugene has 63 DIMES and 112 PENNIES :

the ratio is 63/112=9/16

GCF of (63 and 112) is 7 : 63/7=9 , 112/7=16

7/12 = 0.58333            9/16=0.5625

7/12 is higher than 9/16

Darren has the higher ratio of DIMES TO PENNIES in his piggy bank

this can be solved by finding the percentage 7/12=0.5833=58.3% and 9/16=0.5625 which is 56.25%

Answer:

B y is 3/4 of (x+y)

Step-by-step explanation:

a : is the same thing as a division sign or a fraction bar

so 1 : 3 = 1/3

this ratio says that for every 1 of x, there are 3 y's.

so 1x = 3y or y = 1/3x

x = 1; y = 3

x + y = 4

y / (x+y)

3 / 4

y is 3/4 of (x+y)

Step-by-step explanation:

Hello!

        Part A            

Peter can use the fact that 10% of 87 is 8.70 to find the amount he would save because 40% is just 4 times bigger than 10% so he can take 8.70 from to total of the coat 4 times to find out how much it cost.

        Part B            

Using the same method we know that 10% of 64 is 6.40 so we subtract that from the price of the coat 4 times to find out how much it cost

64 - 6.40 = 57.6

57.6 - 6.40 = 51.2

51.2 - 6.40 = 44.8

44.8 - 6.40 - 38.4

The price of the coat is $38.4

Hope this helps!

Answer:

x = 68 degrees

Step-by-step explanation:

Step 1: We know this is a isosceles triangle

Since we know it is a isosceles triangle it has 2 of the same angle so the unknown side(not x) is 59

Step 2: Use the 2 angles to find 'x'

Angles in a triangle add up to 180 so we subtract 59 x 2 from 180 to get 68

Therefore angle x is 68 degrees

Answer:

Step-by-step explanation:

This is because u have to do the math - LOL

So

- an isosceles has 2 same sides. The pic shows an isosceles triangle

- 2 sides are the same which is 4

- 1 side is different and is 1.5

Same length = Same angles

So

- 4 = 4

- 56 = 56

Total angle - angle 1 - angle 2 = angle 3 or ?

- Total angle = 180

- Angle 1 = 56

- Angle 2 = 56

- Angle 3 = ?

180 - 56 - 56 = 68

Answer: Hi!

Here we're trying to find something called a unit rate. To find the unit rate in this situation, we have to divide the amount of cars by the amount of days:

99 ÷ 9 = 11

Sophia can wash 11 cars in one day.

Hope this helps!

Answer:

[tex]\Huge \boxed{\mathrm{11}}[/tex]

Step-by-step explanation:

She can wash 99 cars in 9 days.

Divide number of cars by number of days.

99 cars / 9 days ⇒ 11 cars/day ⇒ 11 cars per day.

Answer:

$0.50 per pint

Step-by-step explanation:

First, we need to convert cups to pints.

There are 2 cups in 1 pint. We are given 8 cups, which is 4 times 2. So, we multiply 1 pint by 4:

1 * 4 = 4 pints

There are 4 pints in 8 cups.

We also know that 8 cups cost $2, which also means that 4 pints cost $2.

To find the cost per pint, we divide 2 by 4:

2 / 4 = $0.50

Thus, the price is $0.50 per pint.

Answer:

C: y decreases as x increases

Step-by-step explanation:

Notice from this graph, as we move from left to right, the y values are decreasing while the x values are increasing.

This means that the relationship of the line in terms of x and y can be described as, as y decreases, x increase.  Hence you will choose option C.

You can validate this by choosing to definitive points on the line, say the origin (0,0) and (2, -6).  Notice that our x value increased, but our y value decreased.

Answer:

-8/3 + 2/3 (√3)

Where, p = -8/3

q = 2/3

Step-by-step explanation:

Simplify(1-√3)(1/3+√3)

= (1-√3)(1/3+√3)

Expand the bracket

= 1(1/3+√3) -√3(1/3+√3)

= 1/3 + √3 - √3/3 - 3

Collect like terms

= 1/3 - 3 + √3 - √3/3

= (1/3 - 3) + (√3 - √3/3)

= -8/3 + [(3√3 - √3)/3]

= -8/3 + 2√3/3

= -8/3 + 1/3( 2√3)

= -8/3 + 2/3 (√3)

Where, p = -8/3

q = 2/3

Answers:

a = 2

h = 3

k = -3

You have the correct h and k values. Nice work so far.

==========================================================

Explanation:

(h,k) is the vertex. So (h,k) = (3,-3) meaning h = 3 and k = -3

To get the value of 'a', we need to plug in some point on the red graph. Each point is of the form (x,y). We can pick any point we want that isn't the vertex.

Let's pick (0,3) which is the y intercept. I'm picking this because 0 is an easy number to work with

------------

y = a|x-h| + k

y = a|x-3| + (-3) .... plug in the h,k values

y = a|x-3| - 3

3 = a|0-3| - 3 .... plug in (x,y) = (0,3)

3 = a|-3| - 3

3 = a*3 - 3

3 = 3a - 3

3a-3 = 3

3a = 3+3 ... adding 3 to both sides

3a = 6

a = 6/3 ... divide both sides by 3

a = 2

The value a = 2 indicates that the parent function y = |x| has been stretched vertically by a factor of 2. So it is twice as tall as before. Then it has been shifted to place the vertex at (3,-3) as shown in the graph.

------------

You may be wondering why you can't pick on the vertex for (x,y)

Let's see what happens if we use (x,y) = (3,-3)

y = a|x-3| - 3

-3 = a|3-3| - 3 ... plug in (x,y) = (3,-3)

-3 = a|0| - 3 ... uh oh, we get 0 here

-3 = a*0 - 3

-3 = 0 - 3

-3 = -3

We get a true statement, which is nice, but it doesn't tell us anything about what the value of 'a' is. That 'a' term goes away entirely. So I avoided using x = 3 to prevent x-3 from being 0.

We know that the sum of the internal angles of a triangle is 180....

Bringing to our problem:

Angle P + Angle R + Angle S = 180

43 + 79 + Angle S = 180

Angle S = 180 - 43 - 79

Note: this is assuming you haven't reached complex numbers yet

Explanation:

The given equation 13u^2+23u = -112 is the same as 13x^2+23x = -112

and we can add 112 to both sides getting 13x^2+23x+112 = 0

We see the equation is in the form ax^2+bx+c = 0

The discriminant is

D = b^2 - 4ac

D = 23^2 - 4(13)(112)

D = -5295

The negative discriminant means there are no real number solutions.

-----------

Extra info:

If D = 0, then there would be exactly one real number solution.

If D > 0, then there would be two distinct real number solutions.

Answer:

it is complex solution

no real number solution

Step-by-step explanation:

13u²+23u=-112

13u²+23u+112=0  

a=13, b=23 , c=+112

u= (-b±√(b²-4ac))/2a

u=[(-23±√(23)²-4(13)(112)]/2(13)

u=(-23±√-5295)/26

u=(-23±i√5295)/26

Answer:

Step-by-step explanation:

Hello!

It is asking for the answer is p is equal to 3 so we put 3 in for p

3 = 2n - 3

Add 3 to both sides

6 = 2n

Divide both sides by 2

3 = n

The answer is 3

Hope this helps!

Answer:

n = 3

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation:

*3-(2*n-3)=0

Pull out like factors:

*6 - 2n  =   -2 • (n - 3)

Solve:

*-2   =  0 (This has no equation so we solve for the next side.)

*n-3 = 0 (Add 3 to both sides)

The correct option is;

B. The difference of 2 perfect squares

Step-by-step explanation:

Solving a quadratic equation using factoring involves finding the factors of the equation that would yield the result of the quadratic equation

In order to find the roots of the quadratic equation, then the result of the factoring must be equal to zero, in which case, the constant terms in the factors are the solutions of the quadratic equation in opposite sign.

For example, we have;

x² - 5² = 11

We subtract 11 from both sides to get;

x² - 5² - 11  = 11 - 11

x² - 36 = 0

x² - 6² = 0

(x - 6) × (x + 6) = 0

Therefore, x = 6 or -6 which are the opposite sign of the constant terms in the factor.
