How many runners ran at least 3 miles?
Enter your answer in the box.
{ } runners
Answer:
7 runners
Step-by-step explanation:
In order to figure this question out, you need to count them up. Count up all the runners that are plotted from 3 miles on. Anything before that is under 3 miles, so it doesn't count.
After counting them up, you will find that there are 7 runners marked who ran 3 miles or more. So your answer is 7 runners.

The length of a rectangle is twice as long as its width. The width is 104 inches,
Find the perimeter of the rectangle
Answer:
624
Step-by-step explanation:
the width is 104
if the length is doubled, that means the length is 208.
rectangles have 2 sets of equal sides
104 + 104 =208
208 + 208 = 416
416+208 = 624
Answer:
624
Step-by-step explanation:
The width is 104. Now we need to find the length. 104 x 2 - 208. The length is 208. A rectangle has four sides, two of them are the length, and two of them are the width. To find the perimeter, we need to add all of them. 104 + 104 + 208 + 208 = 624.
Hope this helps! If it did, please give brainliest! It would help a lot! Thanks! :D

Pond Critters
Ms. Wilson sets up a pond water aquarium in the classroom. Ms. Wilson tells the class
there are five different kinds of aquatic animals in the aquarium. There are caddis fly
larvae, diving beetles, whirligig beetles, dragonflies and tadpoles.
Ms. Wilson says one-twelfth of the pond animals are dragonflies. One-third of the
animals are caddis fly larvae. One-fourth are tadpoles. There are the same number of
diving beetles as whirligig beetles. If there are six dragonflies, how many pond critters
are in the aquarium? How many caddis fly larvae, tadpoles, diving beetles and whirligig
beetles are in the aquarium? Show all your mathematical thinking.
Answer: There are 72 pond critters in the aquarium. There are 24 caddis fly larvae, 18 tadpoles, 12 diving beetles and 12 whirligig beetles in the aquarium.
Step-by-step explanation:
Given : There are caddis fly larvae, diving beetles, whirligig beetles, dragonflies and tadpoles in the aquarium
One-twelfth of the pond animals are dragonflies
One-third of the animals are caddis fly larvae.
One-fourth are tadpoles.
The same number of diving beetles as whirligig beetles.
Number of dragon flies = 6
Let the total animals are = x, dragon flies are represented by d , caddis fly larvae as c, tadpoles as t , diving beetles as b and whirligig beetles as w.
Now : x = d + c + t+ b + w
[tex]\frac{1}{12}\times x=d[/tex] (1)
[tex]\frac{1}{3}\times x=c[/tex] (2)
[tex]\frac{1}{4}\times x=t[/tex] (3)
[tex]b=w[/tex] (4)
[tex]d=6[/tex] (5)
Comparing 1 and 5
[tex]\frac{1}{12}\times x=6////x=72[/tex]
Thus pond critters are 72.
[tex]c=\frac{1}{3}\times 72=24[/tex]
[tex]t=\frac{1}{4}\times 72=18[/tex]
[tex]d=6[/tex]
Now x = d + c + t+ b + w
72 = 6+24+18+b+b (as b= w)
2b =24
b = 12
Thus w = 12.

how can you change mm to meters
Answer:
Step-by-step explanation:
1 meter = 1000 mm
So, 1 mm = [tex]\frac{1}{1000}[/tex] m
To change mm to meter, divide the given mm value by 1000
Ex: 50 mm = 50 ÷ 1000 = 0.05 m
5 mm = 5 ÷ 1000 = 0.005
Answer:
To convert millimeters to meters, multiply the number of millimeters by 0.001.
To convert meters to millimeters, multiply the number of meters by 1000.
Step-by-step explanation:
1 millimeter is 0.001 meters.
1 meter is 1000 millimeters.
To convert millimeters to meters, multiply the number of millimeters by 0.001.
Example:
This object is 100 millimeters long. How many meters long is it?
100 x 0.001 = 0.1
0.1 meters.
To convert meters to millimeters, multiply the number of meters by 1000.
Example:
This object is 100 meters long. How many millimeters long is it?
100 x 1000 = 100000
100000 millimeters.
A triangle has three angles with the measures of (2x), (2x + 14), and (6x + 6)".
What is the measure of the smallest angle in the triangle?
Answer:
Option c : 32 degree.
Step-by-step explanation:
2x + 2x + 14 + 6x + 6 = 180 degrees
10x = 160
x = 16
2x = 16 *2 = 32 degrees
Answer:
Step-by-step explanation:
Angles in a triangle add up to 180°
You take 2x+2x+14+6x+6=180°
Collect like term and add 2x+2x+6x+14+4=180°
10x+20=180°
10x=180°-20
10x=160÷10
x=16
16*2=32
16*2+14=46
16*6+6=100
Smallest angle is 32

Which of the following points does not lie on the line y = -2x +5?
A. (4-3)
B. (-2,9)
с. (3,1)
D. (-1,7)
E. (2, 1)
Answer:
C (3, 1 )
Step-by-step explanation:
To determine if a point lies on the line, substitute the x- coordinate of the point into the equation and if the value obtained equals the y- coordinate of the point then it lies on the line, otherwise not on line.
A (4 , - 3)
y = - 2(4) + 5 = - 8 + 5 = - 3 ← lies on line
B (- 2, 9 )
y = - 2(- 2) + 5 = 4 + 5 = 9 ← lies on line
C (3, 1 )
y = - 2(3) + 5 = - 6 + 5 = - 1 ≠ 1 ← not on line
D (- 1, 7 )
y = - 2(- 1) + 5 = 2 + 5 = 7 ← lies on line
E (2, 1 ) = - 2(2) + 5 = - 4 + 5 = 1 ← lies on line
Thus (3, 1 ) does not lie on the line → C

Factor the equation. [tex]3x^2+8x-11[/tex]
Like I said you can't factor this. The GCD is 1 so you can't factor it. The GCD must be 2 or higher.
Answer:
(x - 1)(3x + 11)
Step-by-step explanation:
Given
3x² + 8x - 11
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 3 × - 11 = - 33 and sum = + 8
The factors are - 3 and + 11
Use these factors to split the x- term
3x² - 3x + 11x - 11 ( factor the first/second and third/fourth terms )
= 3x(x - 1) + 11(x - 1) ← factor out (x - 1) from each term
= (x - 1)(3x + 11) ← in factored form
