Rachel rides her bicycle due east at 12 kilometers per hour. Amos rides his
bicycle due north at 16 kilometers per hour. If they left from the same point at
the same time, how far apart will they be after 3 hours?
Answer:
they will be 60 kilometers apart.
Step-by-step explanation:
well you use pythagorean theorem
12 × 3
=36
16 × 3
=48
pythagorean theorem states that:
a²+b²=c²
so
48² + 36² =3600
then, because c is squared, you just square root it
√3600 = 60

Answer:
slope is 2/3
Step-by-step explanation:
To solve for slope: y2-y1 / x2- x1.
Two points can be (0,50) and (30,70) since they intercept.
70-50 / 30- 0 = 20/30 = 2/3.
The slope is also going 20 units up and 30 units across which gives you 2/3.

The length of a diagonal of a square is 10 square root of 2 inches. Find the length of one side of the square.
Answer:
10inches
Step-by-step explanation:
Let the length of one side of the square be a
If the diagonal of a square is 10√2 inches
According to pythagoras theorem
a²+a² = (10√2)²
2a² = 100(2)
2a² = 200
a² = 200/2
a² = 100
a = √100
a = 10
Hence the length of one side of the square is 10inches

Answer: 3.50
Step-by-step explanation:
4 ounces x 3 tenders = 12ounces so 3 dollars. then 4 ounses so 50 cents. so 3.00 + 0.50= 3.50

Work out the size of angle x.Give reasons for your answer .
Answer:
75°
Step-by-step explanation:
AD and EH are parallel
So Angle GFE equals to angle FBA
And angle CBA equals 180°-angle FBA= 180°-105°= 75°
Please put the Brainlest
The value of x would be 75 degrees beacuse of corresponding angles on the same line of tranversal.
What are corresponding angles?In literal sense, corresponding means pair wise angles. Like the right corner angles of two triangles etc. But usually we take them as: For two similar figures, the pair by pair similar angles of those two similar figures are called corresponding angles. They are of same measurement.
Given that AD and EH are parallel lines
So Angle GFE is equals to angle FBA.
And angle CBA equals to 180°
Angle FBA = 180°-105°
Angle FBA = 75°
Hence, The value of x would be 75 degrees beacuse of corresponding angles on the same line of tranversal.

What is the equation of this graph?
Answer (assuming it is allowed to be written in slope-intercept form):
[tex]y = -\frac{2}{3} x + 1[/tex]
Step-by-step explanation:
When knowing a line's y-intercept and its slope, you can write its equation using slope-intercept form, or [tex]y = mx + b[/tex].
1) First, find the slope of the line. Read the graph and look at the two points marked on the line - they are (0,1) and (3,-1). Use the slope formula [tex]\frac{y_2-y_1}{x_2-x_1}[/tex] , substitute the x and y values of those points, and solve:
[tex]\frac{(-1)-(1)}{(3)-(0)} \\= \frac{-1-1}{3-0} \\= \frac{-2}{3}[/tex]
Thus, the line's slope is [tex]-\frac{2}{3}[/tex].
2) Now, use the slope-intercept formula, [tex]y = mx + b[/tex], to write an equation. Substitute the [tex]m[/tex] and [tex]b[/tex] for real values.
The [tex]m[/tex] represents the slope, so substitute [tex]-\frac{2}{3}[/tex] in its place. The [tex]b[/tex] represents the y-value of the y-intercept, or the point at which the line crosses the y-axis. Looking at the graph, we can see that the line intersects the y-axis at (0,1). Thus, substitute 1 for [tex]b[/tex]. This gives the following equation and answer:
[tex]y = -\frac{2}{3} x + 1[/tex]
find the equation of a line that is parallel to the straight line 2x-y=-3 and crosses the x-axis at x=-5
Answer:
y=2x+10
Step-by-step explanation:
In line equations its helpful to write your line in the form y = ax + b. This helps because a is always the gadient of the line and b is always the y intercept.
In this case it is y=2x+3
All parallel lines have the same gradient. The gradient of this line = 2.
If the line crosses the x axis at x=-5, then when x =-5 y = 0.
If you put all this in the form y =ax + b you get 0 = 2(-5) +b
So all you need to do to find b is rearrange. b = 10.
Therefore your line has gradient 2 and y intercept 10.
y = 2x + 10

Brown Delivery Company delivers its standard crates using a fleet of vans and trucks. A van can hold up to 20 standard
crates, and a truck can hold up to 35 standard crates. If Brown Delivery Company needs to deliver exactly 270 standard
crates at one time using 12 vehicles, which system of linear equations could be used to determine the number of vans, x,
and the number of trucks, y, needed for this delivery?
x + y = 12
20x + 35y = 270
x + y = 270
20x + 35y = 12
x + y = 12
35x + 20y = 270
x+y = 270
35x + 20y = 12
Answer:
x + y = 12
20x + 35y = 270
Step-by-step explanation:
Let us represent:
The number of vans = x
The number of trucks = y
From the above question, we are told that:
A van can hold up to 20 standard crates, and a truck can hold up to 35 standard crates. If Brown Delivery Company needs to deliver exactly 270 standard crates at one time using 12 vehicles.
Hence, our system of equations is given as:
x + y = 12..... Equation 1
20 × x + 35 × y = 270
= 20x + 35y = 270...... Equation 2

Devon has been saving $5 & $10 for the past four years. Over spring break he wanted to see how much money he has saved up. After counting the money he calculated that he has a total of $395 & had 49 bills. Based on this information, how many $5 & $10 bills does he have?
Answer:
19 five dollar bills
30 ten dollar bills
Step-by-step explanation:
x=number of $5 bills
y=number of $10 bills
x+y=49
x=49-y
5x+10y=395
substitute for x
5(49-y)+10y=395
245-5y+10y=395
245+5y-245=395-245
5y=150
5y/5=150/5
y=30
x=49-30=19
