3√2

Step-by-step explanation:

the 2nd answer

y=3√2

Step-by-step explanation:

f(-3)=(-3)^2+4

=9+4

=13

hope it helps u dear friend

Answer:

Step-by-step explanation:

Given

f(x) = x² + 4

Now

f(- 3) = (-3)² + 4

       = 9 + 4

       = 13

hope it helps :)

Answer:

Is this what you meant?

(2x + 3x) × (3 + 15) = 12x + 36

(5x) × (18) = 12x + 36

90x = 12x + 36

78x = 36

x = 36 / 78

x = 18 / 39

_____________________

or

3(2x+3x) + 15 = 12x + 36

10x + 15 = 12x + 36

-21 = 2x

2x = -21

x = -21/2

Answer:

oh that.is.... um .......ummmmmmmm

Answer:

16 times

Step-by-step explanation:

difference in area = area of bigger circle / area of smaller circle

Area of a circle = πr²

r = radius

imagine the radius of the smaller circle = 1

Area of circle in terms of π= π

radius of the bigger circle = 4 x 1 = 4

Area of bigger circle in terms of π  = π4² = 16 π

16 π /  π = 16  times

Answer:

A

Step-by-step explanation:

3x3x3 = 27

The number above the root symbol is the amount of time you have to multiply a number by itself. When we write the square root symbol the 2 is invisible, just like the 1 with a lone variable (x=1x).

In this case it is a cube root

Answer:

The answer is G

Step-by-step explanation:

All you do is move all the terms not containing x to the right side of the inequailty form: x < 3

Answer:

x = 134

Step-by-step explanation:

Given that,

Five angles of a hexagon measures 119, 129,104,139 and 95 degrees.

We know that,

The sum of interior angles of a hexagon must equal 720 degrees.

So,

119+129+104+139 +95+x = 720

Where

x is the sixth angle

So,

586+x=720

x = 720-586

x = 134

So, the sixth angle is equal to 134.

Answer:

y = -5/2x + 6

Step-by-step explanation:

y = -5/2x + b

-4 = -5/2(4) + b

-4 = -10 + b

6 = b

y = -5/2x + 6

Answer:

It will cost 63.25

Step-by-step explanation:

We can use a ratio to solve

46 dollars       x dollars

--------------- = ---------------

8 people         11 people

Using cross products

46 * 11 = 8x

506 = 8x

Divide each side by 8

506/8 =8x/8

63.25 =x

It will cost 63.25

Answer:

$63.25

Step-by-step explanation:

46/8 = $5.75 each

11 x 5.75 = $63.25

Answer:

[tex]y=\frac{3}{2} x+1[/tex]

Step-by-step explanation:

What we need to know:

1) Find the slope of line P

The slope of a line is equal to the [tex]\frac{rise}{run}[/tex], or the number of units the line moves up over the number of units the line moves to the right.

We can see that for line P, for every 2 units it moves to the right, it moves up 3 units.

Therefore, the slope of line P is [tex]\frac{3}{2}[/tex].

Knowing this, the equation of a line parallel to line P would have a slope of [tex]\frac{3}{2}[/tex] as well. Plug this into [tex]y=mx+b[/tex] as m:

[tex]y=\frac{3}{2} x+b[/tex]

2) Plug the given point Q into [tex]y=\frac{3}{2} x+b[/tex]  to find the y-intercept (b)

[tex]y=\frac{3}{2} x+b[/tex]

Plug in point Q (2,4)

[tex]4=\frac{3}{2} (2)+b\\4=\frac{6}{2}+b\\4=3+b[/tex]

Subtract 3 from both sides

[tex]4-3=3+b-3\\1=b[/tex]

Therefore, the y-intercept of this line (b) is 1. Plug this back into our original equation:

[tex]y=\frac{3}{2} x+b[/tex]

[tex]y=\frac{3}{2} x+1[/tex]

Answer:

the volume of the cone is 339.29

Step-by-step explanation:

Answer:

Volume is 339.29cm

Step-by-step explanation:

Answer:

Step-by-step explanation:

<JKL = 90 ( being inscribed angle in semi circle )

< JKP = 38 ( Inscribed angles on same arc are equal )

So now

<PKL = <JKL - < JKP

        = 90 - 38

        = 52

FINALLY

ARC PL = 2 * < PKL (Relation between arc and inscribed angle )

ARC PL = 2 * 52

             = 104

hope it helps :)

The options aren't given, however, the range of amount spent could be calculated

Answer:

Kindly check explanation

Step-by-step explanation:

Paula purchase 3 dvd and 7 cds and spent between 90 and 100. Each dvd costs the same amount the price of cd is 10 select all amounts that could be the price of the dvd

Given that :

DVD costs the same amount

Number of DVD's = 3

Cost of cds = 10

Number of cds = 7

Total cost of cd's = 10 * 7 = 70

Let the price of DVD = x

Total amount spent = 90 - 100

Lowest price of DVD :

(amount spent - price of cd) / number of dvd

(90 - 70) / 3 = 20 /3 = 6.667

Highest price :

(100 - 70) / 3 = 30 / 3 = 10

Hence the pice of each DVD will range between /

6.6666 and 10.

Hence, prices listed within the range above are possible.

Answer:

120

Step-by-step explanation:

if you do 4200 x 35 it well be 147000 but if you divide 4200 ÷ 35 it will be 120 and in the question said Each so each mean =× or ÷ in this case it's divide

Answer: 3780

Step-by-step explanatio

35 multiply it with 12 cause there are 12 months in a year then subtractEd it with 4200 and 420 cause that is what I got. Then got 3780!

35 x 12 = 420 then 4200 - 420= 3780

Answer:

72.33

Step-by-step explanation:

45 percent of 125 is 56.25 so you subtract that from 125 and get 68.75 and then you do 5.2 percent of 68.75 and get 3.575 which rounds to 3.58 and you add that to 68.75 and get 72.33

Answer:

3.5

Step-by-step explanation:

so this triangle is symmetrical by AA. so x would be symmetrical to 7, and 2.5 is symmetrical to 5.

[tex]\frac{x}{2.5}[/tex] = [tex]\frac{7}{5}[/tex]

x×5=5x

2.5×7=17.5

5x=17.5

x=17.5/5

x=3.5

Answer:

C

Step-by-step explanation:

Pythagorean theorem = a² + b² = c²

Answer:

C.

Step-by-step explanation:

Pythagrean Theorem is on C

Answer:

The surface area of the red square is 180, and the surface area of the blue square is 328. So the full answer is 508.

Step-by-step explanation:

A = 2( width times length +height times length +height times width ) = 2(6 times 3 + 8 times 3 + 8 times 6)=180

A = 2(width times length + height times length + height times width) = 2(2 times 12 + 10 times 12 + 10 times 2) = 328

And 328 + 180 = 508.
