If each square unit represents 3 square feet what is the area of the patio in square feet

Answer:

1. B) 5.7

2. A) 12

3. A) 11.4

4. A) 5.7

5. A) 16.2

6. A) 11.2

7. No, they do not form a right triangle

8. Yes, they do form a right triangle

Step-by-step explanation:

Extra tip: The hypotenuse has to be less than both sides added together, but cannot be more than either of the sides alone.

1.

16² + b² = 17²

256 + b² = 289

256 - 256 + b² = 289 - 256

b² = 33

√b² = √33

b = 5.74 or 5.7

2.

16² + b² = 20²

256 + b² = 400

256 - 256 + b² = 400 - 256

b² = 144

√b² = √144

b = 12

3.

7² + 9² = c²

49 + 81 = c²

130 = c²

√130 = √c²

11.40 or 11.4 = c

4.

7² + b² = 9²

49 + b² = 81

49 - 49 + b² = 81 - 49

b² = 32

√b² = √32

b = 5.65 or 5.7

5.

a² + 5² = 17²

a² + 25 = 289

a² + 25 - 25 = 289 - 25

a² = 264

√a² = √264

a = 16.24 or 16.2

6.

10² + b² = 15²

100 + b² = 225

100 - 100 + b² = 225 - 100

b² = 125

√b² = √125

b = 11.18 or 11.2

7.

15² + 8² = 16²

225 + 64 = 256

289 ≠ 256

8.

5² + 12² = 13²

25 + 144 = 169

169 = 169

Answer:

B

Step-by-step explanation:

The 115° angle is adjacent to both unknown angles in the triangles, thus

unknown angles = 180° - 115° = 65°

The sum of the 3 angles in a triangle = 180°, thus

∠ 1 = 180° - (65 + 80)° = 180° - 145° = 35°

∠ 2 = 180° - (65 + 85)° = 180° - 150° = 30°

Answer:

MISSING LENGTH IS 12 M

Step-by-step explanation:

9+9+ ? + ? = 42m

18+ X + X = 42m

2X=42-18

2X=24

X=12

Answer:

The missing length is 12 meters.

Step-by-step explanation:

9+9+x+x=42

Subtract 9 from both sides

9+x+x=33

Subtract 9 from both sides

x+x=24

2x=24

Divide both sides by 2

x=12

The missing length is 12 meters.

(You don't actually have to multiply it all out, I just did it to make sure you understand)

Answer:

t= ((ln*2)/(0.02)

Step-by-step explanation:

plug 40000 in for P and solve for t

40000=20000e^0.02t

-divide both sides by 20000: 2=e^0.02t

-in order to cancel out e, multiply both sides by the natural log (ln)

ln(2)=0.02t

-divide 0.02 on both sides to get t by its self

Answer: t = ((ln(2)/(0.02))

Answer:

The optimal volume is 63.1142 in3, with a cut of 1.5767 inches

Step-by-step explanation:

If we make a cut of x inches to create the box, the dimensions of the box will be:

Length = 10 - 2x

Width = 9 - 2x

Height = x

So the volume of the box would be:

Volume = (10 - 2x) * (9 - 2x) * x

Volume = 4x3 - 38x2 + 90x

To find the maximum volume, we need to take the derivative of the volume and find the values of x where it is equal to zero:

dV/dx = 12x2 - 76x + 90 = 0

6x2 - 38x + 45 = 0

Using Bhaskara's formula, we have:

Delta = 38^2 - 4*6*45 = 364

sqrt(Delta) = 19.08

x1 = (38 + 19.08) / 12 = 4.7567

x2 = (38 - 19.08) / 12 = 1.5767

Testing these values in the volume equation, we have:

Volume1 = 4*(4.7567)^3 - 38*(4.7567)^2 + 90*(4.7567) = -1.1883

(Negative value for the volume is not valid)

Volume1 = 4*(1.5767)^3 - 38*(1.5767)^2 + 90*(1.5767) = 63.1142

So the optimal volume is 63.1142 in3, with a cut of 1.5767 inches

If you have any questions you can ask

Step-by-step explanation:

Answer:

50 ft

Step-by-step explanation:

This is the pythagorean theorem, so you should use the formula...

a squared + b squared = c squared

Then substitute in the numbers... (remember, a and b are the legs, and c is the hypotenuse)

14 squared + 48 squared = c squared

14 squared = 14 x 14 = 196

Now we have 196 + 48 squared = c squared

48 squared = 48 x 48 = 2,304

Now we have 196 + 2,304 = c squared

Add them together - 2,304 + 196 = 2,500

Now we have 2,500 = c squared

We find the square root of 2,500 which is 50

You should now have 50 = c

That is your answer. Don't forget to add units.

50 ft is your hypotenuse (c)

I hoped this helped

Answer: the missing length is 50

Step-by-step explanation:

in order to figure out the missing number, you have to do the pythagorean theorem, which is a²+b²=c². A is 14 ft, B is 48 ft, and C is the missing length. You have to square each number. 14 will be 196 and 48 would be 2304.

Step-by-step explanation:

1. 2m = 24

Divide each side by 2

2m/2 = 24/2

m = 12

2. y – 9 = 30

Add 9 to each side

y-9+9 = 30+9

y = 39

Multiply each side by 4

x/4*4 = 12*4

x = 48

4. k + 12.5 = 30

Subtract 12.5 from each side

k+12.5-12.5 = 30-12.5

k =17.5

5. 3r = 15.3

Divide by 3

3r/3 = 15.3/3

r =5.1

Answer:

145

Step-by-step explanation:

The the that connects the outside line to the inside line will equal to 180 so you take 180 minus 137 to get 43 and you have two angles for the inside which is 43 and 102. You minus these two number to 180 to get the last missing angle in a triangle because the inside of a triangle is 180 and then minus 180 to 35(Last angle measure) to get the outside of the triangle and you get 145.

Answer:

?=145°

Step-by-step explanation:

The angle 137° is a supplementary angle. So subtract 137 from 180 to find the adjacent angle:

[tex]180-137=43[/tex]

The angle adjacent the angle 137° is 43°. Add this value to the angle measure in the triangle:

[tex]102+43=145[/tex]

Two angle measures within the triangle add up to 145°. The angle measures of a triangle should add up to 180°. Subtract:

[tex]180-145=35[/tex]

The third angle in the triangle is 35°. This angle is also a supplementary angle. Subtract this from 180 to find the measure of angle ?:

[tex]180-35=145[/tex]

The angle ? is 145°.

or

The outer angle of a triangle (angle ?) can be found by finding the sum of the two angles within a triangle, not including the adjacent angle (or ?'s supplementary angle). So find the measure adjacent 137°:

[tex]180-137=43[/tex]

Add the two inner angle measure together:

[tex]43+102=145[/tex]

So angle ? is 145°.

The total ounces of perfume in trials 1, 2, and 3 are 7.8 oz, 7.3 oz, and 7.65 oz.

Given to us,

For Trial 1,

A = 2 oz

B = 4 oz

C = 4 oz

Percentage of rose oil = 22%

weight of trail 1 = A+ B+ C = 2+ 4+ 4 = 10 oz.

Weight of rose oil in trial 1 = weight of trail 1 x Percentage of rose oil in 1

                                           =  10 oz x 22% = 2.2 oz

total ounces of perfume in trial 1

                                               = weight of trail - Weight of rose oil in trial 1

                                               = 10 - 2.2 = 7.8 oz

For Trial 2,

A = 4 oz

B = 2 oz

C = 4 oz

Percentage of rose oil = 27%

Total weight of trail 2 = A+ B+ C = 2+ 4+ 4 = 10 oz.

Weight of rose oil in trial2 = weight of trail 2 x Percentage of rose oil in 2

                                           =  10 oz x 27% = 2.7 oz

total ounces of perfume in trial 2

                                               = weight of trial 2 - Weight of rose oil in trial 2

                                               = 10 - 2.7 = 7.3 oz

For Trial 3,

A = 1 oz

B = 7 oz

C = 2 oz

Percentage of rose oil = 23.50%

Total weight of trail 3 = A+ B+ C = 2+ 4+ 4 = 10 oz.

Weight of rose oil in trial 3= weight of trail 3 x Percentage of rose oil in 3

                                           =  10 oz x 23.50% = 2.350 oz

total ounces of perfume in trial 3

                                             = weight of trail - Weight of rose oil in trial 3

                                             = 10 - 2.2 = 7.8 oz

Hence, The total ounces of perfume in trials 1, 2, and 3 are 7.8 oz, 7.3 oz, and 7.65 oz.

Answer:

[tex]y = 2 (x-7)^{2} +6[/tex] is the equation of parabola.

Step-by-step explanation:

Vertex form of a parabola is given as :

[tex]y = a (x-h)^{2} +k ...... (1)[/tex]

(h,k) is the co-ordinate of vertex of parabola.

(x,y) are the points on parabola.

We are given that vertex is at (7,6) and a point on parabola is (6,8).

h = 7

k = 6

x = 6 and

y =8

Putting all the values in equation (1):

[tex]8 = a (6-7)^{2} +6\\\Rightarrow 8 = a + 6\\\Rightarrow a = 2[/tex]

Putting values of (h,k) and a in equation (1) to obtain the equation of parabola:

[tex]y = 2 (x-7)^{2} +6[/tex] is the equation of parabola with vertex at (7,6) and contains the point (6,8).
