A traveler from Europe wants to
convert the distance 700 miles to
kilometers. If 1 mile equals
1.61 kilometers, what is the distance
between the two cities in kilometers?
Answer: 1,127 km.
Disclaimer: There are a plethora of ways to solve this problem, but I decided to utilize proportions to solve it, as I believe that it is the easiest method to solve these types of questions.
1. Set up your proportion
2. Set up a basic algebraic equation: 1x=700
In other words, what times 1 is 700?
Multiply 1*700, which is 700, and do the same for the bottom.
1.61*700= 1,127
3. The final answer is 1,127 kilometers. Please refer to the pictures attached for a more visual and thorough explanation. Cross mutiplying could also be used. Simply cross multiply in your proportion to get your answer.
The slope between two points (2,b) and (1, -2) is 4. Find b.
Answer:
b=2
Step-by-step explanation:
To get slope given two points, take the difference of the y values and divide it by the difference of the x values.
(This is also called change in y over change in x, or rise over run)
b-(-2)/2-1=4
b+2/1=4
b+2=4
b=2

Circumference and Area questions look at the picture
Note that the formula for the circumference of a circle is πd, while the formula for the area of a circle is πr².
π≈3.14
A. C=πd
Simply plug in the numbers into the formula.
Diameter=Radius*2
17*2=34
C=34(π)
B. (π)(5²)
Plug in the numbers into the formula. Remember that half of the diameter is the radius.
C. (π)(4.5)
There are two possible formulas that could be used to calculate the circumference of a circle: πd and 2πr.
The expression above is simply multiplying the circle's radius times pi. Therefore, it is not a method that could be used to find the circumference of a circle.
D. (π)(6.5²)
Remember that the formula for calculating the area of a circle is πr².
Half of the diameter is 6.5 (13.5/2=6.5). 6.5 cm. is the radius. Now just plug the numbers into the formula.
(π)(6.5²)
Therefore, the last answer choice is the correct answer.

Alyssa is jogging near Central Park. She runs along 65th Street for about 0.19 miles, turns right and runs along Central Park West for about 0.28 miles. She then turns right again and runs along Broadway until she reaches her starting point. How long is her total run to the nearest hundredth of a mile?
A: 0.68 miles
B: 0.81 miles
C: 1.15 miles
D: 1.44 miles
Answer: B: 0.81 miles
Step-by-step explanation:
The find the total distance, you must look for firs the missing side. To get use the formula that is derived from the Pythagorean theorem which states that the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.
The formula for this is: a^2 + b^2 = c^2
So let the first side or a be .19
and the second side be .28
and now we are looking for c which is the missing side
.19^2 + .28^2 = c^20.0361 + 0.784 = .1145
get the square root of .1145
√.1145 = it is approximately 0.34
get the total distance by adding three sides
= .34 + .19 + .28
= 0.81
Answer:
0.68
Step-by-step explanation:
you got to multiply
Find the constant rate of change for the representation,
24x-28y=14
Answer:
6/7
Step-by-step explanation:
The constant rate of change is also know as the slope of the expression
Given
24x-28y=14
Write in standard form y = mx+c
m is the slope
24x-28y=14
-28y = -24x + 14
y = -24x/-28 + 14/-28
y = 6/7 x - 1/2
Compare
mx = 6/7 x
m = 6/7
Hence the constant rate of change is 6/7

Answer:
C. 12
Step-by-step explanation:
Find the percentage of him drawing a blue marble.
4/10 = 0.4
He has a 40% chance of picking blue.
Find 40% of 30.
12
He would draw a blue marble around 12 times.
Answer:
C
Explanation:
So in the bag, there are 10 marbles, and 4 of them are blue, so if he drew from the bag 10 times, we can assume the fraction:
4/10
Next, we see that the denominator, or the number times Cade is drawing from the bag is 30, which makes us multiply most sides of the fraction by 3:
12/30
So I would say 12/30, but again, he wouldn't draw a blue exactly 4 times, and it may be more or less, so either 8/12....
Hope this helps!

Plz help I have a geometry exam soon!!!!! :(
Answer:
a = 93°, b = 120°, c = 150°
Step-by-step explanation:
b + 36 = 78 × 2 => b + 36 = 156 => b = 120°
87 × 2 - b = the minor arc between a and 78
=> 174 - 120 = 54
54 + b + 36 + c = 360
=> 54 + 120 + 36 + c = 360
=> c = 150°
(c + 36) ÷ 2 = a
=> (150 + 36) ÷ 2 = a
=> a = 93°
The two lines graphed below are parallel. How many solutions are there to the system of equations?
Answer:
C. Zero
Step-by-step explanation:
The solution of the system of equations would be the point where they intersect, but since these lines are parallel, they will never intersect, so therefore there are zero solutions.

If p-1/p=2, find the value of p^3+1/p^3. Help me fast.
Answer:
[tex]\\\\\frac{P^3 \ + \ 1}{P^3} = 0[/tex]

HELP ME I WILL HIVE U 5 stars ON IF ITS RIGHT PLZZZ !!!!!!!
Answer:
40
Step-by-step explanation:
The two angles form a right angle
A right angle has a measure of 90 degrees meaning that the sum of the two angles is 90
a + 50 = 90
90 - 50 = 40
Thus, a = 40
missing angle is (40⁰) :)
