Mr. Grayson owns a wood company that sells trees. Mr. Grayson gets a request from a customer to buy a palm tree of a specific height. Mr. Grayson’s tree nursery is very large and is organized by a coordinate plane map system. He finds a palm tree that he thinks might meet the customer’s specifications. The tree is located at coordinates (35, 28). He calls his assistant to come over to help him determine the height of the tree. He asks his assistant where she’s located. His assistant says she is located at (70, 15). Each unit on the coordinate grid represents 1 ft. How far is Mr. Grayson’s assistant from the tree? Round to the nearest tenth. Show your work.

Tina described four triangles as shown below: Triangle A: All sides have length 12 cm.
Triangle B: Two sides have length 10 cm, and the included angle measures 60°. Triangle C: Base has length 15 cm, and base angles measure 40°.
Triangle D: All angles measure 60°.

Which triangle is not a unique triangle? Triangle A Triangle B Triangle C Triangle D

Answers

Answer:

Triangle D is not a unique triangle.

Step-by-step explanation:

Triangle A:  All sides have length 12 cm.

such a triangle will be a unique triangle and it will be an equilateral triangle.

Triangle B: Two sides have length 10 cm, and the included angle measures 60°.

Such a triangle will also be unique because with the help of the given angle measure and and the angles opposite to equal sides are equal we can find the measure of those two angles.

and hence we can construct a triangle with the help of these information.

Triangle C:  Base has length 15 cm, and base angles measure 40°.

Such a triangle will also be unique as a unique triangle could be constructed with the help of these information.

Triangle D: All angles measure 60°.

Such a triangle will be an equilateral triangle but we can't say it will be unique as we can construct infinite number of triangles with different side lengths.

Hence such a triangle is not unique.

A number is 1/7 another number. the difference of the number is 18. assume that you are subtracting the smaller number from the larger number. find the number

Answers

Answer:

21 and 3

Step-by-step explanation:

Let's call the small number x and the larger number y.

According to the problem:

x=(1)/(7)y

And when you substract the smaller number from the larger number you get 18:

y-x=18

substituting the first equation in the second one:

y-(1)/(7)y=18(6)/(7)y=18\n y=(18*7)/(6) =3*7=21\ny=21

the larger number is 21.

Using the first equation to find x:

x=(1)/(7)y\n x=(1)/(7) (21)\nx=3

the smaller number is 3.

a = the smaller number
b = the larger number
a = 1/7 b
b - a = 18
b - 1/7b = 18
6/7b = 18
b = 21
a = 1/7 * 21
a = 3

Answers

Answer:

The first is a Postive slope. the Second is a Zero slope

Step-by-step explanation:

Becuase the first gradully increases. meaning positive

and the 2nd is a zero because there is no slope. it's a stright line. level ground. no up hill or down hill

6b - 49 =2(b - 3)

Answers

You always start by simplifying.
6b-49=2(b-3) becomes 6b-49=2b-6
From there you can group the b's together by subtracting 2b from both sides, leaving you with 4b-49=-6
Now you can get the b's alone by adding 49 (to cancel out -49) to both sides, giving you 4b=43, You're still trying to get b by itself, so what you'll do is divide both sides by 4, giving you b=10.75
6b - 49 =2(b - 3)\n 6b-49=2b-6\n 4b=43\n b=(43)/(4)
