what type of triangle is this?

Answer:

9/16 10/16 11/16 12/16 13/16

Step-by-step explanation:

Step-by-step explanation:

[tex]the \: gradient \: of \: line \: a \: is[/tex]

[tex]m = \frac{4}{1 } \\ m = 4[/tex]

[tex]the \: gradient \: of \: line \: b \: is[/tex]

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

Gradients of line A is equals to [tex]4[/tex] and gradients of line B is equals to [tex]-2[/tex].

" Gradients is defined as the ratio of difference of y-coordinates  to the difference of x-coordinates."

Formula used

Gradients [tex]= \frac{y_{2}- y_{1}}{x_{2}- x_{1}}[/tex]

According to the question,

Given from the graph,

Coordinates of Line A

[tex](x_{1} ,y_{1} ) = ( 3,3)\\\\(x_{2} ,y_{2} ) = ( 4,7)[/tex]

Substitute the value in the formula we get,

Gradient of line A [tex]= \frac{7-3}{4-3}[/tex]

                              [tex]= 4[/tex]

Coordinates of Line B

[tex](x_{1} ,y_{1} ) = ( -1,3)\\\\(x_{2} ,y_{2} ) = ( -2,5)[/tex]

Gradient of line B [tex]= \frac{5-3}{-2-(-1)}[/tex]

                              [tex]= -2[/tex]

Hence, gradients of line A is equals to [tex]4[/tex] and gradients of line B is equals to [tex]-2[/tex].

Answer:

He actually paid a sum of $201.25

Step-by-step explanation:

We simply add the vat value to the cost of the machine

Mathematically, that’s (

175 + 15% of 175

= 175 + (15/100 * 175)

= 175 + 26.25

= $201.25

Answer:

a) $1920, b) $2880, c) $4320, d) $6720

Step-by-step explanation:

a) Interest = Principal(Rate)(time)/100

  Interest = $8000(12)(2)/100

Interest = $1,920

b) Interest = $8000(3)(12)/100

Interest = $2880

c) Interest = $8000(4.5)(12)/100

Interest = $4320

d) Interest = $8000(7)(12)/100

Interest = $6720

True

Step-by-step explanation:

Answer:

Line n: A set of points where the coordinates of each point have a sum of 2

Line m: A set of points where the y-coordinate of each point is 10 less than the x-coordinate

Step-by-step explanation:

Given

Lines m and n (See attachment)

Required

Interpret both lines

First, we pick few coordinates of line m and then line n.

For m

[tex](x_1,y_1) = (13,3)[/tex] -- At point E

[tex](x_2,y_2) = (6,-4)[/tex] -- At point B

[tex](x_3,y_3) = (2,-8)[/tex]  -- At point D

For n

[tex](x_1,y_1) = (-2,4)[/tex] -- At point A

[tex](x_2,y_2) = (6,-4)[/tex] -- At point B

[tex](x_3,y_3) = (12,-10)[/tex]  -- At point C

Test for Statement A:

Set of point with a sum of 2

i.e.

[tex]x + y = 2[/tex]

For m

[tex](x_1,y_1) = (13,3)[/tex] -- At point E

[tex]x_1 + y_1 = 13 + 3 = 16[/tex]

This statement is not true for line m

For n

[tex](x_1,y_1) = (-2,4)[/tex] -- At point A

[tex]x_1 + y_1 = -2 + 4 = 2[/tex]

[tex](x_2,y_2) = (6,-4)[/tex] -- At point B

[tex]x_2 + y_2 = 6- 4 = 2[/tex]

[tex](x_3,y_3) = (12,-10)[/tex]  -- At point C

[tex]x_3 + y_3 = 12- 10 = 2[/tex]

This statement is true for line n

Test for Statement 2:

Set of points where y is x - 10

i.e.

[tex]y = x - 10[/tex]

For m

[tex](x_1,y_1) = (13,3)[/tex] -- At point E

[tex]y_1 = x_1 - 10[/tex]

[tex]3 = 13 - 10[/tex]

[tex]3 = 3[/tex]

[tex](x_2,y_2) = (6,-4)[/tex] -- At point B

[tex]y_2 = x_2 - 10[/tex]

[tex]-4 = 6 - 10[/tex]

[tex]-4 = - 4[/tex]

[tex](x_3,y_3) = (2,-8)[/tex]  -- At point D

[tex]y_3 = x_3 - 10[/tex]

[tex]-8 = 2 - 10[/tex]

[tex]-8 = -8[/tex]

This statement is true for line m

Answer:

6

Step-by-step explanation:

Answer:

D) 6

Step-by-step explanation:

Assumption method:

Assume all are postcards.

Total cost of postcards = 10 × $1

                                       = $10

Difference between total = $22 - $10

                                          = $12

Difference between subjects = $3 - $1

                                                 = $2

No. of magnets = $12 ÷ $2

                          = 6

Answer:

d < -3

Step-by-step explanation:

2.5d+11.4<-1.3d

3.8d+11.4<0

3.8d<-11.4

d < -3

Just isolate and solve for x and remember, what you do to one side, you must do to the other.

Hope this helps!

Answer:

[tex]d < -3[/tex]

Step-by-step explanation:

Move the constant to the right-hand side and change its sign:

[tex]2.5d < - 1.3d - 11.4[/tex]

Move the variable to the left-hand side and change its signs:

[tex]2.5d + 1.3d < 11.4[/tex]

Collect like terms:

[tex]3.8d < - 11.4[/tex]

Divide both sides of the inequality by 3.8:

[tex]3.8 \div - 11.4 = - 3[/tex]

Therefore, the answer is d < -3.

Answer:

14

Step-by-step explanation:

20 times four is 80 so we already have 12 chaperones because there are 3 chaperones for every 20 students.

20 divided by 3 is 6.6

We cannot have .6 of a chaperone so we round up to 7

And since 7 can only go into 20 two times

That means there are two more chaperones

2+12 is 14

There are 14 chaperones for the 92 students

(Hope this helps and hope im right)

Answer:

80(students)

12(chaperons)

Step-by-step explanation:

since total of 92 people in the trip including student and chaperon,add groups of 23 to become 92 or use this equation:

(20+3)×y=92

23y=92

y=92/23

y=4

therefore,

20×4=80(students)

3×4=12(chaperons)

Answer:

Step-by-step explanation:

5000 at 4% =200      (5000*0.04)

5000 at 8% = 400      (5000*0.08)

3,500 at 12% = 420     (3500*0.12)

200+400+420 = 1020

Answer:

139 miles

Step-by-step explanation:

Lori lives 272 miles from her grandparents

411 miles from her aunt

39 miles from her cousins

Therefore the distance in which Lori lives to get grandmother than her aunt can be calculated as follows

= 411 miles - 272 miles.

= 139 miles
