Answer:

A

Step-by-step explanation:

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

∠ A + ∠ B + ∠ C = 180°, so

95° + 35° + ∠ C = 180

130° + ∠ C = 180 ( subtract 130° from both sides )

∠ C = 50° → A

Answer:

hat=£(9*9)/3*24)/3/8/9

Scarf=£1.5

Step-by-step explanation:

Let's suppose hats is the variable h

And Let's suppose scarves is the variable s

3h+2s=12

5h+4s=21

so, 3h+2s=12 which is also 2s=12-3h

so, in the equare 5h+4s=21 we can replace the 4s with 2(12-3h) Now the equation is this:

5h+24-6h=21

*Simplified*

Now 5h-6h= -1h

-1h+24=21

+1h      +1h

on each side.

now the equation is(remember 1h=h): 24=h+21

I think you can do it now.

Now with the cost of the hats, we can use the first equation: 3h+2s=12

h=3

3*3=9

-9    -9

2s=3

s=1.5

Answer:

Arc SN = 65

Step-by-step explanation:

The relationship between these three is

RPQ = 1/2 (arc SN + arc QR)

70 = 1/2 (x + 75)                        Multiply by 2

140 = x + 75                              Subtract 75

x = 140 - 75

x = 65

Answer:

371.54

Answer:

2 hours: 27 miles, 3 hours: 40.5 miles, 3.5 hours: 47.25 miles

Step-by-step explanation:

1.) If a hiker hikes 9 miles in 2/3 of an hour, he will hike 4.5 (Half of 2/3 is 1/3 and half of 9 is 4.5) miles in 1/3 of an hour and 13.5 miles per hour. (1/3 times 3 gives us a whole and 4.5 times 3 is 13.5)

2.) 2 hours: 13.5 * 2 = 27 miles

3.) 3 hours: 13.5 * 3 = 40.5 miles

4.) 3.5 hours: 13.5 * 3.5 = 47.25 miles

9 miles in 2/3 of a hour.

in 1 hour = 9 X 3/2 = 18.2 miles

In 2 hrs = 27 miles

in 3 hrs = 54.6 miles

in 3.5 hrs = 63.7 miles

Answer:

47. 08 meters

Step-by-step explanation:

Given that:

In 48 years between 1842 :

Rate of erosion = 33/50 meters per year

Between 1905 - 1927 (22 years)

Rate of erosion = 7/10 meters per year

Approximately how much total erosion occurred during these two time periods ;

Total erosion that occured within 1842:

Rate of erosion * number of years

(33/50)m * 48

0.66 meters * 48

= 31.68 meters

Total erosion that occured between 1905 - 1927:

Rate of erosion * number of years

(7/10)m * 22

0.7 meters * 22

= 15.40 meters

total erosion which occurred during these two time periods ;

31.68 meters + 15.40 meters

= 47.08 meters

Answer:

48.76%

Step-by-step explanation:

Here is the complete question;

A brand of cereal had 1.21milligrams of iron per serving. Then they changed their recipe so they had 1.8mg of iron per serving. What was the percent increase in iron?

Given

Initial amount of iron in cereal per serving = 1.21mg

final  amount of iron in cereal per serving =1.8mg

Required

Percentage increase in iron

Increment = 1.8mg - 1.21mg

Increment = 0.59mg

% increase in iron = increment/original amount * 100%

% increase in iron = 0.59/1.21 * 100

% increase in iron = 0.4876 * 100

% increase in iron = 48.76%

Hence the percent increase in iron is 48.76%

Answer:

The temperature in degrees after 9 hours is -1.25 degrees Fahrenheit

Step-by-step explanation:

Here, we want to know the temperature after 9 hours

Per hour rise each hour is 3/4 degree = 0.75 degree

In 6 hours that will be 0.75 * 6 = 4.5 degrees

Or hour drop is 1/4 = 0.25 degree

In 3 hours, that will be 0.25 * 3 = 0.75 degree

Since it is a drop, we have -0.75 degree

Temperature after 9 hours will be;

-5 + 4.5 -0.75

= -5.75 + 4.5 = -1.25 degrees fahrenheit

Answer:

it 2

Step-by-step explanation:

18x+3y=-21

slope -intercept form: y=mx+b

move 18x to the other side

sign changes from +18x to -18x

18x-18x+3y=-18x-21

3y=-18x-21

divide both sides by 3 to find slope-intercept form

3y/3=-18x/3-21/3

y=-6x-7
