Answer:
[tex]\sqrt{82}[/tex]
Step-by-step explanation:
Calculate the distance d using the distance formula
d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = (- 2, 6) and (x₂, y₂ ) = (- 1, - 3)
d = [tex]\sqrt{(-1+2)^2+(-3-6)^2}[/tex]
= [tex]\sqrt{1^2+(-9)^2}[/tex]
= [tex]\sqrt{1+81}[/tex]
= [tex]\sqrt{82}[/tex] ≈ 9.06 ( to 2 dec. places )
Answer:
9.06
Step-by-step explanation:
(-2,6) and (-1,-3)
Distance =√(x2−x1)^2+(y2−y1)^2
√(−1−(−2))^2+(−3−6)^2
√(1)^2+(−3−6)^2
√(1)^2+(−9)^2
√1+81=
√82 ≈9.055385138137417

Which of the following is a complex number?
You'll be disappointed to find out these are *all* complex numbers, because the set of real numbers is a subset of the complexes.
Probably the question means to ask, "which of these numbers is strictly non-real?" in which case D would be the answer because it contains the square root of a negative number that introduces the imaginary unit i. All the other options are strictly real numbers.
On one day in January, the temperature in Milwaukee, Wisconsin fell 12°F from the high temperature to a low temperature of -8°F. If t represents the high temperature, what is the value of t?
Answer:
t = 4
Step-by-step explanation:
you have -8 and twelve you equation is x -12 = -8 so we just have to flip the equation around to make it x = 12 -8 which is easy . You just have to make sure you don't get mixed up while flipping the signs.
The value of t is 4.
What is an equation?An equation is a combination of different variables, in which two mathematical expressions are equal to each other.
Given that,
The temperature in January = 12 °F
And the low temperature is = -8 °F
The equation of temperature t can be given as
t= high temperature + low temperature
t= 12 - 8
t=4
The value of t is 4.

Answer:
a) £60
b) 6 weeks

In the first week of July, a record 1 comma 100 people went to the local swimming pool. In the second week, 125 fewer people went to the pool than in the first week. In the third week, 145 more people went to the pool than in the second week. In the fourth week, 185 fewer people went to the pool than in the third week. What is the percent decrease in the number of people who went to the pool over these four weeks? The percent decrease of people who went to the pool is __ %
Answer:
41.36% decrease
Step-by-step explanation:
Since it told us that the total amount of people was 1,100 people, we know our percentage is going to have to be x/1100.
We calculate how many less people came to the pool after the weeks have passed, which totals up to 455 people (455 people decrease).
So,
455/1100 = 0.413636 or 41.36% decrease.

Brian plays basketball. In the past he has made 4 out of every 5 free throws. What is the probability, as a decimal, that Brian will make the next two free throws?
Answer:
0.64
Step-by-step explanation:
4 out of 5 free throws is 0.8 as a decimal.
The probability that Brian will make 2 free throws is 0.8 for the first one, and then 0.8 of that for the second one. That means you multiply the two to get your answer and 0.8 times 0.8 = 0.64.

maddy had twice as many stamps as simon. After maddy sold 60 stamps, simon had twice as many stamps as maddy. how many more stamps did maddy have than simon in the beginning
Answer: 40 stamps
Step-by-step explanation:
Let Maddy = M and Simon = S
Given that maddy had twice as many stamps as simon. That is,
M = 2S ....(1)
After maddy sold 60 stamps, simon had twice as many stamps as maddy. That is,
S = 2( M - 60) .... (2)
Substitutes M for 2S from equation (1) into equation (2)
S = 2( 2S - 60 )
Open the bracket
S = 4S - 120
Collect the like terms
S - 4S = -120
- 3S = - 120
S = 120/3
S = 40
Substitute S into the equation (1)
M = 2 × 40 = 80
Maddy has 80 - 40 = 40 stamp
Therefore, Maddy has 40 more stamps than simon in the beginning.

3/7 of which is 2 1/14
Answer:
4 and 5/6; 29/6.
Step-by-step explanation:
3/7 of x is 2-1/14.
(3/7)x = 29/14
x = (29/14) * (7/3)
x = (29/2) * (1/3)
x = 29/6
3/7 of 4 and 5/6 is 2 1/14.

Use the x-axis as your "timeline", then eliminate incorrect answers.
The y-axis is crossed at x=0,y=5, so that invalidates answer C.
The line is increasing up until x=2, so answer B is wrong.
The line is constant between x=2 and x=10 so answer D is wrong.

A school bus is full as it sets off. At the first stop 3 children get off and at the next stop a third
of the remaining children get off, leaving the bus only half full.
How many children were on the bus at the start?
Answer:
12
Step-by-step explanation:
If there are x children on the bus at the start, after the first stop, there are (x-3) remaining. After two stops, the number on the bus is ...
x/2 = x -3 -(1/3)(x -3)
Multiplying by 6, we have ...
3x = 6x -18 -2(x -3)
3x = 4x -12 . . . . simplify
12 = x . . . . . . . . add 12-3x
There were 12 children on the bus at the start.
_____
Check
After 3 got off at the first stop, there were 12-3 = 9 remaining. 1/3 of those, or 9/3=3 got off at the second stop, so 9 -3 = 6 remained. This is half the original number, as required.

Answer:
a) square numbers
b) 9
Step-by-step explanation:
A square number is a number that can be made by multiplying a whole number by itself(49 is a square number because 7*7=49, 64 is a square number because 8*8=64). The square root of 36 is 6. The square root of 25 is 5. The square root of 16 is 4. Thus, following the pattern, the square root of 9 is 3.

What is the difference from the point (-6,2) to the point (2,17)?
Answer: Distance is 17
Step-by-step explanation:
[tex]d = √((x2-x1)2 + (y2-y1)2)[/tex]
[tex](x2-x1) = (2 -6) = 8[/tex]
[tex](y2-y1) = (17 - 2) = 15[/tex]
Add them all together
[tex](8)2 + (15)2 = 64 + 225 = 289[/tex]
Square 289
[tex]\sqrt{289} =17[/tex]
The segments shown below could form a triangle.
By the Triangle Inequality Theorem, the sum of two sides should be greater than the length of the third side, while the difference of these two sides should be less than the length of this third side. Normally you would take the absolute value of the difference of these two side as you wouldn't know which is greater than the other!
The simplest way to prove whether these line segments can form a triangle, is by going against this theory. Let us prove that the line segment don't form a triangle. As you can see, adding 7 and 1 is greater than 1, respectively 7 and 7 is greater than 1. Thus -

Gabriella drives her car 400 miles and averages a certain speed. If the average speed had been 7 mph less she could have traveled only 350 miles in the same length of time what is her average speed
Answer:
Gabriella's average original speed was 56 [tex]\frac{mi}{h}[/tex]
Step-by-step explanation:
Let's use the equation that defines the average speed "v" of Gabriella during the time (t) that her trip took:
[tex]v = \frac{distance}{time} \\v=\frac{400}{t}[/tex]
Next let's write a similar average speed equation for the case in which she drove at (v - 7 mi/h) during the same time "t" and covered 350 miles:
[tex](v-7)=\frac{350}{t}[/tex]
Notice that the time "t" in the denominator appears equally in both equations we wrote, so let's isolate them on the right:
[tex]\frac{v}{400} =\frac{1}{t} \\and\\\frac{(v-7)}{350} =\frac{1}{t}[/tex]
now equal both expression since they both share the same value on the right, and solve for the unknown "v":
[tex]\frac{v}{400} =\frac{(v-7)}{350} \\350\,v=400\,(v-7)=\\350\,v=400\,v-2800\\2800=50\,v\\v=\frac{2800}{50} \,\,\frac{mi}{h}\\v=56\,\,\frac{mi}{h}[/tex]
