2.Steve travels at 36 kilometre per hour for 20 seconds how far does he go
Answers
Answer:
1.150 seconds or 2.5 minutes
2. 0.2km
Step-by-step explanation:
1. 1.5 x 1000=1500
1500/10=150
150/60=2.5minutes
2. 60mins = 36km -Divide both sides by 60 to get how far he would go in 1 minute/60 secs
1min/60secs=0.6km -Divide both sides by 3 to get how far he would go in 20 secs
20secs=0.2km
A restaurant offers three sizes of coffee and four differerſt types of coffee.
Coffee can be ordered with or without cream and with or without sugar.
The restaurant also has six bagel options. A bagel can be ordered plain, with
butter, or with cream cheese. How many different ways can you choose a
coffee and bagel at this restaurant?
Answers
=======================================================
Work Shown:
There are,
3 sizes of coffee4 types of coffee2 choices for cream (you pick it or you leave it out)2 choices for sugar (same idea as the cream)This means there are 3*4*2*2 = 12*4 = 48 different coffees. We'll use this value later, so let A = 48.
There are 6 bagel options. Also, there are 3 choices in terms of if you order the bagel plain, with butter, or with cream cheese. This leads to 6*3 = 18 different ways to order a bagel. Let B = 18.
Multiply the values of A and B to get the final answer
A*B = 48*18 = 864
There are 864 ways to order a coffee and bagel at this restaurant.
--------------
If you're curious why you multiply the values out, consider this smaller example.
Let's say you had 3 choices of coffee and 2 choices for a bagel. Form a table with 3 rows and 2 columns. Place the different coffee choices along the left to form each row. Along the top, we'll have the two different bagel choices (one for each column).
This 3 by 2 table leads to 3*2 = 6 individual table cells inside. Each cell in the table represents a coffee+bagel combo. This idea is applied to the section above, but we have a lot more options.

6. A rectangular piece of land measures 0.7 km by
of wire. What length of wire is needed ?
0.5 km. Each side is to be fenced with four rounds
Answers
Answer:
9.6km / 9600m
Step-by-step explanation
B= 0.5km
L = 0.7km
perimeter of a rectangle = 2(L+B)
= 2( 0.7 + 0.5)
= 2.4km
wire for one round is 2.4km
wire for 4 rounds = 2.4 x 4
= 9.6km wire is required.
Hence, 9.6km wire is required to fence the rectangular piece of land 4 times.

Step-by-step explanation:
[tex]\frac{3}{5 }x -7=23[/tex]
[tex]\frac{3x}{5} -7=23[/tex]
[tex]\frac{3x}{5} -7+7=23+7[/tex]

Answer:
(C) X = 50
Step-by-step explanation:
(3/5)*x-7 = 23 // - 23
(3/5)*x-23-7 = 0
3/5*x-30 = 0 // + 30
3/5*x = 30 // : 3/5

how do you find the axis of symmetry?
Answers
Answer:
The axis of symmetry always passes through the vertex of the parabola . The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola. For a quadratic function in standard form, y=ax2+bx+c , the axis of symmetry is a vertical line x=−b2a .
Step-by-step explanation:
Answer:
x=-b/2a
Step-by-step explanation:
axis of symmetry is the line that across the vertex from a parabola(ax^2+bx+c).
The expression to find vertex is -b/2a
Thus, x=-b/2a is a vertical line that across the vertex aka the axis of symmetry.

1) The bakers at Healthy Bakery can make 290 bagels in 10 hours. How many
bagels can they bake in 23 hours? What was that rate per hour?
Answers
Answer:
667 bagels in 23 hours
29 bagels per hour
Step-by-step explanation:
We first find the unit rate in bagels per hour.
(290 bagels) / (10 hours) = 29 bagels/hour
Now we find the number of bagels made in 23 hours.
23 hours * 29 bagels/hour = 667 bagels

Answer: 30
Step-by-step explanation: Assuming that the side lengths correspond with one another you can set up a ratio to solve
It should look something like this: 15/25 = 18/x
With this equation set up you can solve by cross multiplying. 25(18)=15x
Then start sloving:
25(18)=15x
450=15x
450/15=15x/15 (divide both sides by 15)

Answers
Answer:
The answer is: Find the slopes of AB and AC. If the product of the slopes is -1, then the sides meet in a right angle.
Step-by-step explanation:
From Analytical Geometry, two lines are perpendicular to each other if and only if [tex]m_{1}\cdot m_{2} = -1[/tex], where [tex]m_{1}[/tex] and [tex]m_{2}[/tex] are the slopes of each line, respectively. According to this, the following expression must be observed:
[tex]m_{AB} \cdot m_{BC} = -1[/tex] (1)
Each slope can be determine by definition of the slope of a Secant Line:
[tex]m_{AB} = \frac{y_{B}-y_{A}}{x_{B}-x_{A}}[/tex] (2)
[tex]m_{BC} = \frac{y_{C}-y_{B}}{x_{C}-x_{B}}[/tex] (3)
Where:
[tex]x_{A}[/tex], [tex]x_{B}[/tex], [tex]x_{C}[/tex] - x-Coordinates of points A, B and C.
[tex]y_{A}[/tex], [tex]y_{B}[/tex], [tex]y_{C}[/tex] - y-Coordinates of points A, B and C.
If we know that [tex]x_{A} = 0[/tex], [tex]y_{A} = 0[/tex], [tex]x_{B} = 50[/tex], [tex]y_{B} = 0[/tex], [tex]x_{C} = 18[/tex] and [tex]y_{C} = 24[/tex], then the relationship between slopes is:
[tex]m_{AB} = \frac{0-0}{50-0}[/tex]
[tex]m_{AB} = 0[/tex]
[tex]m_{BC} = \frac{24-0}{18-50}[/tex]
[tex]m_{BC} = -\frac{3}{4}[/tex]
[tex]m_{AB}\cdot m_{BC} = 0\cdot \left(-\frac{3}{4} \right)[/tex]
[tex]m_{AB}\cdot m_{BC} = 0[/tex]
Which means that both line segments are not perpendicular to each other.
In a nutshell, we need to find the slopes of AB and CB, if the product between both slopes is -1. Then, the sides meet in a right angle.

what is an equation of the line that passes through the point (5,1) and is parallel to the line x+y=9
Answers
To find the line that goes through (5,1), we can use a blank equation y=mx+b. We know that m=-1, so we can use the given point to find b:
y=mx+b
Y=-x+b
1=-5+b
6=b
So the line would be y=-x+6.
