Answer:

11/4

Step-by-step explanation:

2 times 4 equals 8 and plus 3 equals 11 and dem is 4 so 11/4

Answer:

[tex]\frac{11}{4}[/tex]

Step-by-step explanation:

[tex]2\frac{3}{4}[/tex]

To get an improper fraction do the multiply and add shortcut.  Do the denominator times the whole number ( 2 x 4).  You will get 8, next add 8 with 3.  You still keep the denominator, so your final result is [tex]\frac{11}{4}[/tex]

Answer:

8

Step-by-step explanation:

it just is

Answer:

8

Step-by-step explanation:

Convert to a decimal

32%

move two decimal points to the left

0.32

multiply

0.32 times 25 = 8

Answer:

We conclude that the  standard form of the given function is:

[tex]f(x)=-9x^2-90x-221[/tex]

Hence, option B is correct.

Step-by-step explanation:

We know that the standard form of the quadratic function is of the form

[tex]f\left(x\right)\:=\:ax^2\:+\:bx\:+\:c[/tex]

Given the function

[tex]f(x)=-9\left(x\:+\:5\right)^2\:+\:4[/tex]

as (x+5)² = x² + 10x + 25

[tex]f(x)=-9\left(x^2+10x+25\right)+4[/tex]

Expanding  -9(x² + 10x + 25) = -9x² - 90x - 225

[tex]f\left(x\right)\:=-9x^2-90x-225+4[/tex]

simplifying

[tex]f(x)=-9x^2-90x-221[/tex]

Therefore, we conclude that the  standard form of the given function is:

[tex]f(x)=-9x^2-90x-221[/tex]

Hence, option B is correct.

11.82

Step-by-step explanation: I know this because 21.32-9.50= 11.82

Answer:

A and C luv <3

Step-by-step explanation:

So if you solve for x using the first equation, you get: x = 5y - 5.

From there you can plug that into the second equation which would give you:

7y-5y+5=-23

Simplifying from that point, you get y = -9.

Now that you have one of the values, you can solve for x by plugging it back into the equation we made (x = 5y - 5) and getting to the answer x = -40.

Answer:

Tens

Step-by-step explanation:

Answer:

19) 28°

20) 60°

21) 17°

Step-by-step explanation:

19)

Supplementary angles:

(x + 12)º + 140º = 180º

x + 12 + 140 = 180

x = 180 - 140 - 12

x = 28º

20)

Angles at a point:

(- 24 + x)° + 24° + 300° = 360°

- 24 + x + 24 + 300 = 360

x = 360 - 300

x = 60°

21)

Vertically opposite angles:

(1 + 3x)° = 52°

1 + 3x = 52

3x = 52 - 1

3x = 51

x = 17°

The cost to manufacture a hair clip is $0.50. With a markup of 200%, what is the selling price of this hair clip?

Given data

cost to manufacture a hair clip is $0.50

markup of 200%

Required

The selling price

We know that

Mark up percent= selling-cost/cost*100

200= selling-0.5/0.5*100

200-selling= 50/0.5

200-selling= 100

selling= 200-100

selling = 100

Hence the selling price is $100

A Responding variable.

Step-by-step explanation:

Think about it, if you had a car and there were two different ramps, one short and one was high, would the car's speed be different from the other ramp? Yes it would, and since its changing its a responding variable, because that changes as well.

Answer:

$27.12

Step-by-step:

So, we first need to learn how much money the tax is. We can find it like this

8.5 8.5x12.50

------ x 12.50 = ----------------

100 100

106.25

= ------------- = 1.0625 ~~ $1.06

100

The tax is $1.06

So now, the only thing left is to add

12.50 + 1.06 = $13.56

13.56x2 = $27.12 (for both gifts)

In total, both gifts cost $27.12 with tax.

In total, both gifts cost

Cut diameter in half to find radius

9/2 = 4.5

radius = 4.5

This is the formula for area of a circle:

pi * radius^2

pi * 4.5^2

20.25pi

Now find pi:

20.25 * pi = 63.6

Answer:

63.6 cm is the area

Answer:

63.6

Step-by-step explanation:

1. A = πr²

2. Find the radius (r). Since the radius of a circle is the diameter/2, the radius is 9/2, which is 4.5

3. Now that we know the radius, we plug it into our formula: A = π(4.5)²

4. Simplify: A = 3.14(20.25)

5. A = 63.62

6. Rounding to the nearest tenth makes your answer 63.6

Answer:

a = 60

b = 60

c = 120

Step-by-step explanation:

For a;

a + 120 = 180

This is because angles on a straight line are supplementary

a = 180-120

a = 60

a = b = 60

This is because they are corresponding angles and corresponding angles are equal

c = 120

This is because they are alternate exterior angles and alternate exterior angles are equal

Answer:

The value of n = 4 and  

The value of x = [tex]\frac{5}{3}[/tex]

Step-by-step explanation:

Method I:

As given, 12x -20=n (3x-5)      .........(1)

Firstly , take 12x - 20

As 12x - 20 can be written as 4(3x - 5)

∴ equation (1) becomes

4(3x - 5) = n (3x-5)

Divide the equation by (3x-5) , we get

4 = n

Method II:

As given, 12x -20=n (3x-5)

⇒12x - 20 = 3nx - 5n

⇒12x - 3nx = 20 - 5n

⇒3x(4 - n) = 5( 4 - n)

Divide the equation by (4-n) , we get

3x = 5

⇒ x = [tex]\frac{5}{3}[/tex]

∴ we get

n = 4 and  x = [tex]\frac{5}{3}[/tex]

Now, check that value of n and x satisfies the equation or not

12([tex]\frac{5}{3}[/tex]) - 20 = 4( 3([tex]\frac{5}{3}[/tex]) - 5)

⇒4(5) - 20 = 4(5 - 5)

⇒20 - 20 = 4(0)

⇒ 0 = 0

Hence , we get

The values of x and n satisfies the equation

so, we get

n = 4 and  x = [tex]\frac{5}{3}[/tex]

Answer:

I believe it is four dollars

Answer:

x = 3

Step-by-step explanation:

(4/5)^x = 64/125​ means that 4^x / 5^x = 64/125

x can only be 3 because 4^3 = 64 and 5^3 = 125

Answer:

4

Step-by-step explanation:

The distance between the two points is (-1,-4) - (-5,-4)

Step-by-step explanation:

(n+6)^2-(n+2)^2=(n+6-n-2)*(n+6+n+2)=4*2*(n+4)=8*(n+4) so it is always a multiple of 8
