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°.

Answer:

8y = - 6

Step-by-step explanation:

Given the 2 equations

x + 6y = 9 → (1)

- x + 2y = - 15 → (2)

Adding the 2 equations term by term gives

(x - x) + (6y + 2y) = (9 - 15), that is

8y = - 6

Answer:

8y = -6

Step-by-step explanation:

I got it right on Edge 2020

Also: Plug in the slope 8 and the y-intercept -6 to check the answer. It is correct.

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:

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°

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:

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.

Answer:

see below

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

3. X/4 = 12

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

Hey!!!!

Here's your answer:

1. 2m=24

or,m=24/2

m=12

2. y-9=30

or,y=30+9

y=39

3. 3x=12

or,X=12/3

x=4

4. k+12.5=30

or,k=30-12.5

k=17.5

5. 3r=15.3

or,r=15.3/3

r=5.1

Good luck on your assignment

Your answer is y = -3x + 1

To find the equation of the line we need both the slope and where it intercepts the y-axis. We are given where it intercepts the y-axis because they tell us it goes through the point (0, 1) and this is a point where x = 0, so it must be on the y-axis.

The equation for finding the slope of a line given two points is [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex] where [tex](x_{1},y_{1})[/tex] and [tex](x_{2},y_{2})[/tex] are points on the line. Using this, we can substitute in the points we're given and get:

(-5 - 1)/(2 - 0) = -6/2 = -3

Therefore our slope is -3 and our intercept is 1, so the final answer is y = -3x + 1

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

Step-by-step explanation:

We can use a ratio to solve

550 mg         x mg

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

6 ounces       16 ounces

Using cross products

550* 16 = 6x

Divide each side by 6

8800/6 =x

4400/3 =x

Change to a mixed number

1466 2/3 mg of sodium

Answer:

1466⅔ mg

Step-by-step explanation:

oz : mg

6 : 550

16 : X

X/16 = 550/6

X = 550/6 × 16

X = 4400/3

X = 1466⅔ mg
