Answer:

1A. acute. all of the angles are under 90%. acute is under 90%, right is 90%, and obtuse is over 90%

2A. scalene. isosceles is all sides are the same length, and equilateral is all sides are the same length AND all the angles are 60%. with scalene all sides can be different lengths, and angles can be different

3. no. the rule for making a triangle is that any 2 sides added up, must be more than the 3rd side. so 6+2, 6+4 work, but 2+4 is 6, which is not greater than 6, the third side

Step-by-step explanation:

Sami's error is in the second line of working

2x = 6x - 4  ← correct substitution ( subtract 6x from both sides, Sami has added 6x )

- 4x = - 4 ← correct second line ( divide both sides by - 4 )

x = 1

Substitute x = 1 into either of the 2 equations and evaluate for y

Substituting into the second equation

y = 2x = 2(1) = 2

solution is (1, 2 )

Answer:

The answer is y= -50x + 725 so (D)

Answer:

The amount of money raised

Step-by-step explanation:

The amount of basket balls depends on the money rasied and is therefore dependant, that leaves the money, which is completely independent.

The amount of the money that they've raised.

Answer:

Constant - A symbol having a fixed numerical value.

Proportionality - Equality between two ratios.

Answer:

180 in^2

Step-by-step explanation:

to find the height you need to look at the triangle and apply pythagorean theorem

5^2=x^2=13^2

25+x^2=169

x^2=144

x=12

now we can find the area of the parallelogram:

b*h=area

15*12=180 in^2

The area of the parallelogram is 180 in^2

B (the second one)

Step-by-step explanation:

The thin yellow line in A only goes from 14-30. However, the correct numbers listed range from 12-30. Line B matches up with this data

Answer:

8km

Step-by-step explanation:

The three points form a right-angled triangle with 15km as the height and 17km as the hypotenuse.

To find the distance between Lowell and the port which is the base use the pythagorean theorem.

=√17² - 15²

=8km

Step-by-step explanation:

Answer:

1/8

Step-by-step explanation:

The probability of getting tails on a single flip is 1/2.

Each of the flips is an independent event so you must multiply the probability of getting tails on each flip together.

So, your answer will look like this

[tex]\frac{1}{2}[/tex] x [tex]\frac{1}{2}[/tex] x [tex]\frac{1}{2}[/tex] ; which equals;

1/8

Answer:

1/8

Step-by-step explanation:

To calculate the probability you have to name all possible results first. If you mark a result of a single coin flip as  H  for heads or  T  for tails all results of  3  flips can be written as:

Ω = { ( H , H , H ) , ( H , H , T ) , ( H , T , H) , ( H , T , T ) , ( T , H , H ) , ( T , H , T ) , ( T ,T , H ) , ( T , T , T ) }

Each triplet contains results on  1st,  2 nd and  3 rd coin. So you can see that in total there are  8  elementary events in  Ω.

| Ω |  =  8

Now we have to define event  A  of getting tails three times.

The only elementary event which satisfies this condition is  ( T , T , T )  so we can write that:

A  =  { ( T, T , T ) }

| A |  =  1

Now according to the (classic) definition of probability we can write, that:

P ( A )  =  | A|/  | Ω |  =  1 /8

So finally we can write the answer:

The Probability of getting 3 tails in 3 coin flips is  1 /8 .

Answer:

The slope is 2

The y-intercept is 3

The equation is y = 2x +3

Step-by-step explanation:

The equation goes up 2 squares and over 1 square. 2/1 = 2

For y-intercept, look at the y-axis

The equation is supposed to be written as y = mx + b

m being the slope and b being the y-intercept.

Answer:

x = -3

Step-by-step explanation:

The vertex lies on the axis of symmetry, whose x-coordinate is halfway between -9 and 3:  x = -3

Answer:

x = 4

Step-by-step explanation:

1. Write the equation

3/4x = 2x - 5

2. Get the variables on the same side

Let's subtract 2x! Now, since math is a veryyy jealous subject, you're going to do it on the other side too!

-1.25x = -5

3. Divide both sides by -1.25

x = 4

Thank you for the points!!!

Answer: 34.54feet

Step-by-step explanation:

Thw circumference of the pool will be calculated by using the formula:

= 2πr

where

π = 3.14

r = 5.5

Therefore, circumference = 2πr

= 2 × 3.14 × 5.5

= 34.54feet

Therefore, the circumference of the pool to the nearest hundredth is 34.54feet.

A = 8

B = 7

C = -3

D = 6

E = 1

F = 2

Code: 2 (7 + 6) + 8 [1 -(-3)]

Code: 2 (7 + 6) + 8 (1 + 3)
