Find The Missing Length Indicated

Answers

Answer 1

Answer:

15

Step-by-step explanation:

Answer 2

Answer:

21

Step-by-step explanation:

It is given that two lines are parallel, and hence the corresponding angles are congruent, by corresponding angles postulate. It is also given that the triangles in the photo share an angle, by the reflexive property, the shared angle is congruent. Hence one can use angle-angle to determine that the two triangles in the picture are similar.

Using this, one can set up a proportion with the sides. The ratios of any two corresponding sides are the same as any other two corresponding sides in the triangle, respectively, this is due to the corresponding parts of similar triangles theorem.

[tex]\frac{9+12}{12}=\frac{49}{49-?}[/tex]

Simplify,

[tex]\frac{21}{12}=\frac{49}{49-?}\\\\\frac{7}{4}=\frac{49}{49-x}[/tex]

Cross products,

[tex](7)(49-?) = (4)(49)\\\\343-7?=196[/tex]

Inverse operations,

[tex]343-7?=196\\-343\\\\-7? = -147\\/-7\\\\?=21[/tex]

The trend line passes through (10,9) and (35,0). Write an equation for the trend line.

Answers

Answer: Solution :  

Step 1 :

Make a scatter plot of Lily’s running data.

Step 2 :

To draw a trend line, use a straight edge to draw a line that has about the same number of points above and below it. Ignore any outliers.

Step 3 :  

Find the slope of the trend line.

The line passes through points (2, 20) and (4.5, 45).

Use the slope formula.  

m  =  (y2 - y1) / (x2 - x1)

Substitute x1, = 2, y1 = 20, x2 = 4,  and y2 = 45.

m  =  (45 - 20) / (4.5 - 2)

m  =  25 / 2.5

m  =  10

Step 4 :  

Find the y-intercept of the trend line.

Slope-intercept form equation of a line :  

y  =  mx + b

Plug y = 20, m = 10 and x = 2.  

20  =  10 · 2 + b

20  =  20 + b

Subtract 20 from both sides.  

0  =  b

Step 5 :  

Use your slope and y-intercept values to write the equation.

Slope-intercept form equation of a line :  

y  =  10x + 0

So, the equation for the trend line is

y  =  10x

Answers

Answer:

30.4%

1000 at £1.10

1000 x 1.10 = £1100

35% of 1000 is given away

1000 - 35% = 1000 - 350 = 650 left

35% of £1100 = £385, subtract to get £715 pounds worth of pins left

650 are left, with 385 pounds lost

60% of 650 = 390 pins sold at £3 each

40% of 650 = 260 sold at £5 for 2

3 x 390 = £1170 made from the first lot

260/2 = 130 x 5 = £650 made from the second lot

£1170 + £650 = £1820 from sales

Sales - cost to make - losses (giveaways) = profit value

1820 - 1100 - 385 = 335 pounds of profit

To find the gross profit margin, we take the profit, and find what percentage of the production cost it is.

335 is about 30.45% of 1100

30.45%, which is 30.4% to 1 decimal place.

1. What is 7/50 as a Percentage?

2. What is 3/25 as a Percentage?

3. What is 3/16 as a Percentage?

Please help!

Answers

1. What I do is get the 7/50 to have the denominator as 100 so I just double the 50 and the seven and get 14/100 so it’s 14%.

2. Same thing except 25 goes into 100 four times so I multiple the 3 and 25 by four and get 12/100 so it’s 12%.

3. Do 3 divided by 16, and you get .1875. So that’s 18.75% or you can do 100 divided by 16 and get 6.25. Then you multiply the 6.25 times the 3 and get 18.75%
