Which value from the set {3, 12, 18, 27} makes true?

????????????

8^2 +2^2 is 68 because you only square the integer. In (8 + 2)^2, you square the product of the equation.

Answer:8^2+2^2=68 and (8 + 2)^2=100

Step-by-step explanation:

8^2+2^2

=64+2^2

=64+4

=68

(8+2)^2

=10^2

=100

Answer:

90°> =Acute

90°< =Obtuse

(90°= )= Right

Answer:

a = 2/3

Step-by-step explanation:

(4(x+1) + 20 )/(x+1) = 16

4x + 4 + 20 = 16x + 16

12x = 8

x = 2/3

Answer:

[tex] - \frac{1}{2} [/tex]

its down 1 over 2 each time

Answer:

No

Step-by-step explanation:

(4, 10)

y ≤ 2x + 1

To determine if (4, 10) is a solution to the inequality, we want to plug in the given values.

10 ≤ 2(4) + 1

[multiply] 10 ≤ 8 + 1

[add] 10 ≤ 9

Determine if this statement is true.

10 is greater than 9; therefore (4, 10) is not a solution to this inequality.

Hope this helps!

Answer:

No

Step-by-step explanation:

If you plug in 10 for y and 4 for x, you will get 10 ≤ 9 which is false.

Answer:

x = 11

y = 1

Step-by-step explanation:

N : M

8 : 1

8 N = 1 M

since there is 1 M per every 8 N, y would be 1

to find x, just take 88 and divide it by 8 to get 11

Answer:

Cows produce milk per day = 330 gallons

Step-by-step explanation:

Given - Milan raises dairy cow he has 165 cows. Each cow produced

             2 gallons of milk every day.

To find - How many gallons did the cows produce per day ?

              Show solution using grid method.

Proof -

Given that,

Total cows Milan raises = 165

Now,

Given,

1 cow produce milk = 2 gallon

⇒ 165 cows produce milk = 165 × 2 gallons

Now,

By using grid method , we have

165 × 2

X                       100                        60                         5

2                        200                       120                        10

⇒ 165 × 2 = 200 + 120 + 10 = 330 gallons

∴ we get

Cows produce milk per day = 330 gallons

Answer:

y=90x+60

Step-by-step explanation:

x=months

y=dollars

Find dollars/month by finding the slope.

(3, 330), (5, 510)

-> (510-330)/(5-3) -> 90

Since its a constant rate, the function will be in the form, y=mx+b, and since we found the slope we can plug m=90.

y=90x+b

To find be, we simply substitute one of the points.

330=90(3)+b

b=60

Thus, plugging it in,

y=90x+60

Answer: B, is the answer

x = -411

Step-by-step explanation:

Number = x

Quotient of  a number and 3 : [tex]\frac{x}{3}[/tex]

(x/3) increased by (-7) : [tex]\frac{x}{3}+ (-7)[/tex]

[tex]\frac{x}{3} -7 = - 144\\\\\frac{x}{3}= -144 + 7\\\\\frac{x}{3}= -137\\\\x = -137*3[/tex]

x = - 411

Answer:

-411

Step-by-step explanation:

x / 3 + -7 = -144

x / 3 = -144 + 7

x = -137 x 3

x = -411

Answer:

Step-by-step explanation:

1  Yes they are right angles, it is a right angle because you solve it with a Sine equation

2 the hypotenuse is the longest side

3.  If the squares of the two shorter sides add up to the square of the hypotenuse, the triangle contains a right angle.

Answer:

C. : 5t

Once we find out the number of tables at the reception, we can then multiply the number of tables to 5t.

Answer:

4 years

Step-by-step explanation:

Given data

Simple interest= $400

Principal= $2000

Rate= 5%

The simple interest formula is given as

SI=PRT/100

substitute and solve for T

400=2000*5*T/100

cross multiply

400*100= 10000*T

40000=10000T

T= 40000/10000

T= 4 years

Hence the time taken is 4 years

Answer:

i) 60°

ii) 14.7 cm

Step-by-step explanation:

length of Arc BA = 8.4 cm

length of radius = 8 cm

angle AOC = 45°

BO = AO = CO = 8 cm

i) What is the measure of Angle BOA

= length of Arc BA  / Radius

= 8.4 / 8  = 1.05 radians = 60.16° ≈ 60°

ii) what is the length of arc BAC

= radius * angle BAC  * [tex]\pi /180[/tex]

angle BAC = angle AOC + angle BOA

                  = 45° + 60° = 105°

hence length of arc BAC

= 8 * 105 * [tex]\pi /180[/tex]

≈ 14.7 cm

Answer:

Answer:

  D)  (f⋅g)(x)=8x2−2x−15

Step-by-step explanation:

  (f·g)(x) = f(x)·g(x) = (2x -3)(4x +5) = 2x(4x +5) -3(4x +5)

  = 8x² +10x -12x -15

  (f·g)(x) = 8x² -2x -15

Answer:

16 = 3x

Step-by-step explanation

Find the diagram attached.

Perimeter = sum of all its sides

Sum of all its sides= x+x+x

Sum of all its sides = 3x

Given perimeter = 16in

Equating both;

3x = 16

x = 16/3

x = 5.33in

Hence the value of x is 5.33 and the required equation is 16 =3x

Answer:

y= -3/4 +3

Step-by-step explanation:

slope-intercept form formula is y=mx+b

 mx= slope

 b= y-intercept

Therefore, if you input the numbers into the equation it is

y=-3/4 +3

it is 3 because this point is located at 3 on the y-axis

Answer:

15.925

Step-by-step explanation:

Answer:

2.76 pints

Step-by-step explanation:

Given that:

Tottal amount of paint used = 6.9 pints

The faction of white paint used = 3/5

Hence, Amount of white Paint used :

3/5 * 6.9 = (3 * 6.9) / 5 = 4.14 pints of white paint.

Pints of blue paints used :

Total pints - pints of white used

6.9 - 4.14 = 2.76 pints of blue paint

Answer:

$30

Step-by-step explanation:

s = shorts

t = tshirts

s + 2t = 60

s + 3t = 75

s + 2t = 60

rewrite

   -2t     -2t

s = 60 - 2t

s + 3t = 75

plug in

(60 - 2t) + 3t = 75

solve

60 - 2t + 3t = 75

60 + t = 75

-60       -60

t = 15

s + 2t = 60

plug in

s + 2(15) = 60

s + 30 = 60

    -30    -30

s = 30
