What is the distance between (5,2) and (0, -2)
Step-by-step explanation:
the distance between 2 points can be seen as the Hypotenuse of a right-angled triangle with the legs being the x and y coordinate differences.
and so, we use Pythagoras
c² = a² + b²
with c being the Hypotenuse (the side opposite of the 90 degree angle).
distance² = (5 - 0)² + (2 - -2)² = 5² + 4² = 25 + 16 = 41
so, the distance is sqrt(41) = 6.403124237...
How do the 2s in 12.5 and 0.912 compare?
A The value of the 2 in 12.5 is 11,000 the value of the 2 in 0.912.
B The value of the 2 in 12.5 is 1100 the value of the 2 in 0.912.
C The value of the 2 in 12.5 is 10 times the value of the 2 in 0.912.
D The value of the 2 in 12.5 is 1,000 times the value of the 2 in 0.912.
Answer:
D The value of the 2 in 12.5 is 1,000 times the value of the 2 in 0.912
Step-by-step explanation:
The value of a digit in a number can be found by setting the other digits to zero.
The value of 2 in 12.5 is 2.
The value of 2 in 0.912 is 0.002.
The ratio of values is 2.000/0.002 = 2000/2 = 1000.
The value of 2 in 12.5 is 1000 times the value of 2 in 0.912.
Answer:
D

The chart shows the sizes and prices of different sized boxes of Alex's favorite cereal.
Step-by-step explanation:
Compare the rates
Whichever has the smaller rate is the best deal.
remember, to be able to compare both cereal boxes they must have the same unit of measure (grams with grams, ounces with ounces, etc.)
Answer:
Price of box of cereal #1
---------------------------- = $ per ounce(or other unit)
Size of box #1 (in ounces,
or some other unit)

HELP!! I'm not sure what goes in the blank.
Answer:
10[tex]sin^{2} ([/tex]β[tex])[/tex]
Step-by-step explanation:
We can find this two ways, first by seeing in the step after it, cosines are canceled out. Since you already have 10[tex]sin^{2} ([/tex]β[tex])[/tex] on the next step, you can assume that (since only the cosines changed and the cosine next ot the blank was removed), the value is 10[tex]sin^{2} ([/tex]β[tex])[/tex].
You can also use double angle formulas from the previous step:
(sin(2β) = 2 sin(β) cos(β))and find that:
5 sin (2β) sin(β) = 5 * (2 sin(β) cos(β)) sin(β)) = (10 sin(β) sin(β)) cos(β) =
10[tex]sin^{2} ([/tex]β[tex])[/tex] cos(β)
But since cos(β) is already present, we can see that the answer is 10[tex]sin^{2} ([/tex]β[tex])[/tex]

AB:BD = 3:4
AC:CD = 3:2
Work out AB:BC:CD
Answer:
15:6:14
Step-by-step explanation:
AB:BD is split into a total of 3+4=7 parts.
AC:CD is split into a total of 3+2=5 parts.
So, if the two ratios are put on a number line together with the points A, B, C, and D, the number line would be split into a total of 35 parts (the LCM of 7 and 5).
AB would be (3/7)*35=15.
CD would be (2/5)*35=14
BC would be 35-(15+14)=6
So, the ratio is 15:6:14.

Answer:
55º
Step-by-step explanation:
The 125º angle makes a straight angle (180º) with the one next to it. This makes the angle next to it (adjacent angle) 55º. According to the rules of a transversal, the adjacent angle said above and angle 2 are alternate interior angles, making them equal.

Correct me if I am incorrect.
a room that needs to be tiled is 12 1/2 feet wide by 14 feet long. tiles that mesure 2x2 are $0.79 per tile. Tiles that measure 3x3 are 1.25 per tile. which size tile should be used for this project to save the most money? How many tiles would be needed? How much would you spend on them? HELP PLEASE!
Answer:
Step-by-step explanation:
Area of the room is 12.5(14) = 175 ft²
2x2 tiles are 4 ft²
175 /4 = 43.75 tiles so 44 will be needed
44($0.79) = $34.76
3x3 tiles are 9ft²
175/9 = 19.4444... so 20 will be needed
20($1.25) = $25.00
the larger tiles will cost $9.24 less than the smaller tiles.
Obviously some of the tiles will need to be cut to fit as the length and width of the room are not always a uniform number of tiles for either side.
Which of the following is NOT an equivalent expression for the confidence interval given by 161.7
Choose the correct answer below.
O A. 161.7 +27.8
B. 175.6 -13.9
O C. 175.6 + 13.9
OD. (161.7.189.5)
According to the confidence interval given, the non-equivalent expression is:
A. [tex]161.7 \pm 13.9[/tex]
The interval given is:
[tex]161.7 \leq \mu \leq 189.5[/tex]
Which can also be written as: (161.7.189.5)
The point estimate is the halfway point of the interval, hence:
[tex]\overline{x} = \frac{161.7 + 189.5}{2} = 175.6[/tex]
The margin of error is half the difference of the bounds, hence:
[tex]M = \frac{189.5 - 161.7}{2} = 13.9[/tex]
According to the point estimate and to the margin of error, the interval can also be written as:
[tex]175.6 - 13.9 \leq \mu \leq 175.6 + 13.9[/tex]
[tex]175.6 \pm 13.9[/tex]
Hence, the only expression which is non-equivalent is:
A. [tex]161.7 \pm 13.9[/tex]

Step-by-step explanation:
The dance team held 2 fundraisers to earn money for uniforms. During the second fundraiser, the team raised $450. The team raised a total of $620 for uniforms during both fundraisers. How much money did the dance team raise at the first fundraiser?
Answer:
The dance team raised 170$ during the first fundraiser
Step-by-step explanation:
to find how much the first fundraiser earned let's make an equation and make the first fundraiser the variable x
The equation would be:
x+450=620
so we would take away 450 from both sides
x+450-450=620-450
which would make the equation
x=170
meaning that the first fundraiser raised 170$

Answer:
$100
Step-by-step explanation:
sum the parts of the ratio, 2 + 5 = 7 parts , then
$350 ÷ 7 = $50 ← value of 1 part of the ratio , then
2 parts = 2 × $50 = $100 ← smaller share

In the figure, what would be represented by c^2
A the sum of the lengths of legs a + b
B the area of the rectangle with diagonal
c the length of the hypotenuse of the triangle
D the area of a square constructed on the hypotenuse
Answer:
D
Step-by-step explanation:
We can go through each answer to see if it's right
A
In a right triangle, with c opposite the right angle, we know that
a²+b² = c²
The answer is stating that a+b = c². Unless both a and b are either 0 or 1, this is incorrect
B
The area of a rectangle is equal to length * width, or in this case, a* b. Compare this with our equation of
a²+b² = c² and this is incorrect
C
The hypotenuse, or the side opposite the right angle, is c. The answer is stating that c = c². This is incorrect unless c = 1 or c = 0
D
The square constructed on the hypotenuse would have a side length of c. The area of a square is length², or in this case, c². c² = c² so this is correct
