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:

Step-by-step explanation:

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

Answer:

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.

P.S I would appreciate Brainliest or whatever thats called!

Answer:

It's the middle one

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:

im guessing because its a slope were trying to find the slope intercept so y1~mx1+b on desomos or y=mx+b in actual equation form

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:

$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

The answer is 7x/12 - 1/2. Its the first option in your picture. Hope this helps .

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

Answer:

3x² + 2x - 6+(x² - 4x + 10)

3x² + 2x - 6+x²-4x+10

3x²+x²+2x-4x-6+10

4x²-2x+4

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°

Im guessing its 3.43

Answer:

40 sweets

Step-by-step explanation:

Let june have x sweets

may has 3x/4 sweets

April has x/2 sweets

total sweets is 90

Adding all sweets =

x/2+3x/4+x = 90

9x = 360

x = 40

Therefore June has 40 Sweets

Answer:

If you multiply the 7 by 15 using the AZB formula you will get the asnwer^5 to divide the answer by .05

Step-by-step explanation:

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.

Answer:

A and C luv <3

Step-by-step explanation:

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
