Answer:
Miguel's distance covered = 10 + 14.29 * t
Gabby's distance covered = 17.40 * t
Step-by-step explanation:
Recall that in order to convert km to miles we do:
1 km = 0.62137 mi. therefore the conversion of speeds from km to miles, so we write the distance covered for each biker in miles, we have:
23 km/h = 14.29 mi/h
and 28 km/h = 17.40 mi/h
For Miguel, the distance (D1 in miles) covered will be represented by:
D1 = 10 + 14.29 * t
where t is t the variable that represents the time in hours, and D1 is the distance covered in miles.
For Gabby the distance D2 equation is given by:
D2 = 0 + 17.40 * t

A function graph of a line with two points (-3,-2) and (-1,2) with an x axis of negative five to five and a y axis of negative five to five
9514 1404 393
Answer:
y = 2x + 4
Step-by-step explanation:
You have the graph, so you can read the slope and y-intercept from it. The line goes up 2 units for each unit to the right, so the slope is ...
slope = rise/run = 2/1 = 2
The y-intercept is where the graph crosses the y-axis, at y=4.
The slope-intercept form of the equation for a line is ...
y = mx + b
where m is the slope (2) and b is the y-intercept (4). Your equation is ...
y = 2x +4

Answer:
The value of x is 3
Step-by-step explanation:
∵ Quadrilateral ABCD is congruent to quadrilateral JKLM
∴ AB = JK and BC = KL
∴ CD = LM and AD = JM
∵ BC = 8x + 7
∵ KL = 31
∵ BC = KL
→ Equate their right sides
∴ 8x + 7 = 31
→ Subtract 7 from both sides
∵ 8x + 7 - 7 = 31 - 7
∴ 8x = 24
→ Divide both sides by 8 to find x
∴ [tex]\frac{8x}{8}[/tex] = [tex]\frac{24}{8}[/tex]
∴ x = 3
∴ The value of x is 3
Ramon would like to plant a garden where each row has the same combination of plants. If
Ramon has 27 tomato plants, 15 cucumber plants and 6 basil plants, what is the greatest number of rows the garden can have if Ramon uses all of the plants?
Answer:
48
Step-by-step explanation:
The greatest number of rows that can be formed in the garden will be 3.
What is the highest common factor?The Highest Common Factor (HCF) of two numbers is the highest possible number that is divisible by both numbers.
In other words, the highest common factor is the common factor between the two numbers but it should be the highest among all common factors.
As per the given,
Ramon has 27 tomato plants, 15 cucumber plants, and 6 basil plants.
Factors of 27 = 1, 3, 9, and 27.
Factors of 15 = 1, 3, 5 and 15
Factors of 6 = 1, 2, 3 and 6
The GCF of 27,15 and 6 is 3.
Thus, only three raws are possible.
Hence "The greatest number of rows that can be formed in the garden will be 3".

Kam can make 72 cookies in 3 hours, Madison can make 128 cookies in 4 hours. How many hours would it take them to make 200 cookies together?
Answer:
3.7 hours
Step-by-step explanation:
Answer:
3.7 hours
Step-by-step explanation
Kam
x = 72/3 . = 24 cookies/h
Madison
x = 120 / 4 = 30 cookies/hour
Now we write and equation where "t" will be time
24t + 30t = 200
54t = 200
t = 200/54
t = 3.7 hours

Answer:
Ashley = 79
Step-by-step explanation:
[tex]Average=\frac{Carla+Bev+Ashley}{3}=78\\\\\frac{80+75+Ashley}{3}= 78 \\\\\frac{155+Ashley}{3}=78\\\\\frac{155+Ashley}{3}*\frac{3}{1} =78*3\\\\155+Ashley=234\\[/tex]
Subtract 155 from both sides;

Answer:The slope is 6/7
Step-by-step explanation:
when finding the slope you will need to move the 6x to the other side of the equation by subtracting which gives you 7y=14-6x and all that is left is to divide by 7 which gives y=14-6/7y
Answer:
6x - 7y = 14
⇔ 6x - 14 = 7y
⇔ 6/7.x - 2 = y
=> the slope is 6/7

Step-by-step explanation:
How many factors of 100 are also multiples of 5?
Let us write the factors of 100. A factor of 100 can only be a multiple of five if it is divisible by five.
Divisibility rule of 5: A number can only be divisible by five if the ones digit of the number is a five or 0.Factors of 100 ⇒ numbers divisible by 100 ⇒ 1, 2, 4, 5, 10, 20, 25, 50, 100
When checking each factor of 100;
1 is not a multiple of 5 ⇔ not divisible by 5.2 is not a multiple of 5 ⇔ not divisible by 5.4 is not a multiple of 5 ⇔ not divisible by 5.5 is a multiple of 5 ⇔ divisible by 5.10 is a multiple of 5 ⇔ divisible by 5.20 is a multiple of 5 ⇔ divisible by 5.50 is a multiple of 5 ⇔ divisible by 5.100 is a multiple of 5 ⇔ divisible by 5.⇒ Five factors are multiples of 5.
Therefore, five factors of 100 are multiples of 5.

which line is parallel to y=8x+11?
Answer:
Any line with a slope of 8 is parallel to y = 8x + 11. Some examples are:
y = 8x + 5
y = 8x + 1000
y = 8x +9
It doesn't matter what the y-intercept as long as the slope remains the same for a parallel line.

A number t multiplied by −4 is at least −25.
Answer:
[tex]t\leq 6.25[/tex] in decimal form
[tex]t\leq \frac{25}{4}[/tex] in fractional form
Step-by-step explanation:
-4 times a number t is greater than or equal to - 25. This is what they mean by at least.
[tex]-4t \geq -25[/tex]
Solve for t.
[tex]t\leq \frac{-25}{-4}[/tex] , we flip the inequality because we are dividing by a negative number.
