Eber ran 3 miles. He stopped to take a break every {3}{4) mile.How many times did Eber stop, including his final stop at the end of the run?
Answer:
4 times
Step-by-step explanation:
The total model is 3 miles, divided by 3/4 equals the multiplication problem 3/1 times 3/4 but use the reciprocal of 3/4 which is 4/3 so it would be 3/1 times 4/3 which is 12/3 which is equivalent to 4. :)
There are 4 times did Eber stop.
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Eber ran 3 miles.
And, He stopped to take a break every 3/4 mile.
Now,
Let number of times stop = x
So, We can formulate;
⇒ 3/4x = 3
⇒ x = 3 × 4 / 3
⇒ x = 12/3
⇒ x = 4
Thus, There are 4 times did Eber stop.

Suppose that in one week in November in St. Louis, the temperature dropped by an average of 4 degrees every day. The temperature at the beginning of the week was 65 degrees. Write an equation that relates the temperature (t) to the number of days that have passed (d). helpppp
Answer:
t = 65 - 4d
Step-by-step explanation:
Linear Modeling
The temperature in St. Louis dropped by 4 degrees every day in one week.
When d days have passed, the temperature will have dropped by 4d degrees.
We know the temperature t at the beginning of the week was 65 degrees.
Thus, when d days pass, the linear model for the temperature t is:
t = 65 - 4d

Determine the solution to the following system of equations: x + y = -3x - y = 1
(-2,3)
(-1,-2)
(0,0)
No Solution
Answer:
( -1,-2)
Step-by-step explanation:
x + y = -3
x - y = 1
Add the two equations together to eliminate y
x + y = -3
x - y = 1
------------------
2x = -2
Divide by 2
2x/2 = -2/2
x = -1
Now find y
x+y =-3
-1 +y = -3
-1+1 +y = -3+1
y = -2

Belleville High School offers classes on three different foreign languages. Let A be the event that a student is in eleventh grade, and let B be the event that a student is enrolled in French class. A 5-column table has 4 rows. The first column has entries Tenth grade, eleventh grade, twelfth grade, total. The second column is labeled Spanish with entries 107, 56, 89, 252. The third column is labeled French with entries 122, 68, 82, 272. The fourth column is labeled German with entries 6, 14, 8, 28. The fifth column is labeled Total with entries 235, 138, 179, 552. Which statement is true about whether A and B are independent events? A and B are independent events because P(A∣B) = P(A). A and B are independent events because P(A∣B) = P(B). A and B are not independent events because P(A∣B) ≠ P(A). A and B are not independent events because P(A∣B) ≠ P(B).
Answer:

solve the following equation-7x-4y=-4 -9x-5y=-6
Answer:
[tex]\boxed{x = 4~~and~~ y = -6}[/tex]
.
Step-by-step explanation:
-7x - 4y = -4 (times 5) -35x - 20y = -20
-9x - 5y = -6 (times 4) -36x - 20y = -24
.
Eliminate both equations
[tex]-35x - 20y = -20[/tex]
-36x - 20y = -24
[tex]x = 4[/tex]
.
Substitute the value of x to one of equations
[tex]-7x - 4y = -4[/tex]
[tex]-7(4) - 4y = -4[/tex]
[tex]-28 - 4y = -4[/tex]
[tex]-4y = - 4 + 28[/tex]
[tex]-4y = 24[/tex]
[tex]y = \frac{24}{-4}[/tex]
[tex]y = -6[/tex]

CITIES: The distance between New York City, New York, and Boston, Massachusetts, is 187 miles, and the distance between New York City and
Hartford, Connecticut, is 97 miles. Hartford, Boston, and New York City form a triangle on a map. What must the distance between Boston and
Hartford be greater than?
Answer:
Greater than 90 miles
Step-by-step explanation:
Use the triangle inequality theorem, since the cities form a triangle.
This theorem states that the sum of any 2 sides of a triangle has to be greater than the length of the third side.
We can find what the length of the third side has to be greater than by subtracting 97 from 187:
187 - 97
= 90
So, the distance has to be greater than 90 miles.

Step-by-step explanation:
the length of a rectangular sing is 5 time its width. if the sign perimeter is 24 inches. what is the sign area ?
Answer:
20 in²
Step-by-step explanation:
Assuming that the width of the sign is x, then from the question, we're told that the length is 5 times it's width, so
b = x inches
l = 5x inches
Again, we're told that the perimeter of the sign is 24 inches, and we know already that the perimeter of a rectangle is given as
Perimeter = 2(l + b), substituting this, we have
24 = 2(5x + x)
24 = 10x + 2x
24 = 12x
x = 24 / 12
x = 2 inches.
Since x is the width of the rectangle, and it's 2 inches, we use it to find the length of the sign.
l = 5 * 2
l = 10 inches.
Then, we are asked to find the area of the sign. Area of a rectangle is given as
A = l * b, so if we substitute, we have
Area = 10 * 2
Area = 20 square inches

The drawing should have a scale of 400:1.
What is scale?A scale is a group of levels or numbers that are applied to a certain system of measurement or comparison.
Given, the drawing length is 7cm and the real length is 28 meters.
real length in cm = 2800. hence,
Scale of drawing = 2800: 7 = 400 : 7
Therefore, 400: 1 would be the scale of the given drawing.

If Arron's boat travels 9 mph and the river runs 4 miles mph in still water.how long will it take to travel 18 miles upstream
Answer: It will take Aaron's boat 3³/₅ hours to travel 18 miles upstream.
That is 3.6 hours or 3 hours and 36 minutes.
Step-by-step explanation:
Traveling upstream, the boat's speed will be reduced by the speed of the river current.
9 - 4 = 5mph
