if abc is an isosceles triangle and m∠A=40º,what are possible measures for angles B and C

Answers

Answer:

They could both be 70

Step-by-step explanation:

The reason why is because if you subtract 40 from 180 you get 140 and that can be evenly split in 2 ways by 70.

An isosceles triangle is one with two equal-length sides. The possible measures for ∠B and ∠C are 70°.

What is an isosceles triangle?

An isosceles triangle is one with two equal-length sides. It is sometimes stated as having exactly two equal-length sides, and sometimes as having at least two equal-length sides, with the latter form containing the equilateral triangle as a particular case.

Since in an isosceles triangle the measure of any two angles is equal to each other. Therefore, assuming that ∠B and ∠C are those equal angles.

Now, given that the measure of ∠A is 40°. Therefore, the sum of the measure of all the angles of the triangle can be written as,

∠A + ∠B + ∠C  = 180°

40° + ∠B + ∠C = 180°

40° + ∠B + ∠B = 180°

2 ∠B = 180° - 40°

2 ∠B = 140°

∠B = 140°/2

∠B = 70°

∠B = ∠C = 70°

Hence, the possible measures for ∠B and ∠C are 70°.

2. If you enjoy wasting time, is that time really wasted?

Can you answer it??
Only answer if you can answer it
(well it says tht these two are unanswerable questions) ​

Answers

Step-by-step explanation:

to be honest in my opinion

1.)the impossible makes things possible nothing is possible untill it goes through impossible (simply implying the impossible makes things possible)e.g when you undergo anything hard you learn to not give up making that thing possible in the end

2.)one should not enjoy wasting but should enjoy making and building up time for fun and important things in life like hanging out with your family and friends that's a result of making time for enjoyment instead of wasting it lol

Which expression is equivalent to the given expression?
3(x – 7) + 4(x2 – 2x + 9)

Answers

Answer: 14

Step-by-step explanation: Factoring  x2-2x+9  

The first term is,  x2  its coefficient is  1 .

The middle term is,  -2x  its coefficient is  -2 .

The last term, "the constant", is  +9  

Step-1 : Multiply the coefficient of the first term by the constant   1 • 9 = 9  

Step-2 : Find two factors of  9  whose sum equals the coefficient of the middle term, which is   -2 .

The first term is,  4x2  its coefficient is  4 .

The middle term is,  -5x  its coefficient is  -5 .

The last term, "the constant", is  +15  

Step-1 : Multiply the coefficient of the first term by the constant   4 • 15 = 60  

Step-2 : Find two factors of  60  whose sum equals the coefficient of the middle term, which is   -5 .

     -60    +    -1    =    -61  

     -30    +    -2    =    -32  

     -20    +    -3    =    -23  

     -15    +    -4    =    -19  

     -12    +    -5    =    -17  

     -10    +    -6    =    -16

Two maps are made of a park. The scale from the park to map A is 30 mi to 6 cm. The length of Great Oaks Trail is 4.5 cm on map A. The scale from the same park to map B is 24 mi to 3 cm. The length of Salamander Trail is 3.5 cm on map B. 1. What is the actual length (in miles) of Salamander Trail?

Answers

Answer:

The actual length of Salamander Trail is 28 miles

Step-by-step explanation:

Here, we want to calculate the actual length of salamander trail.

From the question, we are told that a a distance of 3cm on the map B is 24 miles in the park

So now, we have length of 3.5 cm and we want to calculate what is the actual length in miles

From the question on map B;

3 cm = 24 miles

so

3.5 cm = x miles

x * 3 = 24 * 3.5

x = (24 * 3.5)/3

x = 8 * 3.5 = 28 miles

Answer:

  a.  300 ≤ m ≤ 350

  b.  18,000 ≤ p ≤ 21000

  c.  no

Step-by-step explanation:

a. If we let m represent the monthly payment, the absolute value equation is ...

  |m -325| ≤ 25

  -25 ≤ m -325 ≤ 25 . . . . rewrite as a compound inequality

  300 ≤ m ≤ 350 . . . . . . . add 325

The range of affordable payments is $300 to $350 per month.

__

b. If financing is for 5 years, that's a total of 5×12 = 60 monthly payments. For a car price of p, the monthly payment is p/60, so the above inequality becomes ...

  300 ≤ p/60 ≤ 350

Multiplying by 60 gives the range of affordable car prices:

  18000 ≤ p ≤ 21000

An affordable car will have a price between $18,000 and $21,000 (inclusive).

__

c. If the 0% offer is extended to 6 years, the maximum affordable car price can be 6/5 of the upper limit of the range just found:

  6/5×$21,000 = $25,200

This is still less than the price of the car you want.

You cannot afford to buy the car you want.

Step-by-step explanation:

The formula to calculate speed is s=d/t. If the distance is 2,000 m/s and the time is 25 seconds, you plug in the numbers into the formula for speed. 2,000/25=80

The satellite's acceleration (speed) is 80.

N only comes up from 0 on the x-axis, so that's the first part of the coordinate.

Now for the y-axis. The y-axis is the vertical line on the grid. Point N seems to be on the number 4 of the y-axis.
