This size running track is usually called a 400-meter track. However, if a person ran as close to the "inside" as possible on the track, they would run less than 400 meters in one lap. How far away (in meters) from the inside border would someone have to run to make one lap equal exactly 400 meters?
Answer:
its 0 because its -400-400=0

Triangle HEF is the image of triangle HGF after a reflection across line FH. Write a congruence statement for the 2 congruent triangles.
The required statement for the 2 congruent triangles is 1. EF = FG, 2. EH = GH, and ∠E = ∠G.
Given that,
Triangle HEF is the image of triangle HGF after a reflection across line FH. To determine a congruence statement for the 2 congruent triangles.
In congruent geometry, the shapes that are so identical. can be superimposed to themselves.
Here,
Since triangle HEF is the image of triangle HGF after a reflection across line FH.
Implies,

A machine can blow up 20 balloons in 4 min.
How many balloons can it blow up in 60 min?
Answer:
120
Step-by-step explanation:
all you have to do is multiply 20*60
Answer:
The machine can blow up 300 balloons in 60 min.
Step-by-step explanation:
60 ÷ 4 = 15. 15 x 20 = 300. We know it takes 4 minutes to blow up 20 balloons. 4 minutes is only 1/15 of 60, so that means you have to blow up 20 balloons 15 times, which will take 60 minutes, and in that 60 minutes, you blew up 300 balloons.

Hey can anyone help with this question please and thank you
Answer:
(7x-4)°= (3x+28)°. ( :. m || n, so it is alternate angle)
7x° - 4° = 3x° + 28°
4x° = 32°
x = 32/8
x = 4°
Answer:
x = 8
Step-by-step explanation:
< (7x - 4)° and < (3x + 28)° are Alternate interior angles that do not have a common vertex on alternate sides of the transversal, t. Therefore, they have the same measure.
We can establish the following equality statement to solve for x :
< (7x - 4)° = < (3x + 28)°
Subtract 3x from both sides:
7x -3x - 4 = 3x - 3x + 28
4x - 4 = 28
Add 4 to both sides:
4x - 4 + 4 = 28 + 4
4x = 32
Divide both sides by 4 to solve for x:
4x/4 = 32/4
x = 8.
To verify whether the value of x is correct, substitute x = 8 into the equality statement:
< (7x - 4)° = < (3x + 28)°
< [(7(8) - 4]° = < [3(8) + 28]°
< (56 - 4)° = < (24 + 28)°
< 52° = < 52° (True statement. Therefore, the correct answer is x = 8).

Aluminum bronze consists of copper and aluminum, usually in the ratio of 10:1 by weight. If an object made of this alloy weighs 77 pounds, how many pounds of aluminum does it contain?
Answer:
The correct answer is (A). Copper and aluminum in the ratio of 10:1 means 10 parts copper to 1 part aluminum.
Step-by-step explanation:
7 pounds of aluminum in aluminum bronze by by weight.
What is Ratio?Ratio is defined as a relationship between two quantities, it is expressed one divided by the other.
What is percentage?The percentage is defined as the ratio expressed as a fraction of 100.
The percentage is denoted by sign of %.
For example, if XYZ scored 46% marks in his test, it means that he scored 46 marks out of 100. It is written as 46/100 in the fraction form and 46:100 in terms of ratio.
Aluminum bronze consists of copper and aluminum in the ratio of 10:1 by weight
The ratio of copper and aluminum in aluminum bronze = 10:1
Let, aluminum in aluminum bronze by weight = x pound
And copper in aluminum bronze by weight = 10x pound
Since object made of this alloy weighs 77 pounds
So, x + 10x = 77
11x = 77
x = 7
Hence, 7 pounds of aluminum in aluminum bronze by by weight

Answer:
-4[tex]\leq[/tex]x<3
Step-by-step explanation:
1)Break this into 2 case, equal to 0 and and less than 0.
2)The number equals zero if its numerator is 0 which happens when x=-4.
3) A fraction is less than 0 it is negative. Negative fractions are either +/- or -/+, so we have two subcases.
3a) For +/- the numerator is positive when x>-4 and denominator is negative when x<3. Putting those two together we have -4<x<3.
3b)For -/+ the numerator is negative when x<-4 and the denominator is positive when x>3 however those two values don't overlap.
4) Putting this together we have -4[tex]\leq[/tex]x<3

We know that mid - point of a line segment divides it into two equal parts, that is it divides the segment in the ratio of 1 : 1, so let's find the coordinates of the mid point of line segment joining points (-9 , 3) and (5 , 7).
let the coordinates of the points be x and y, now

value of x :
[tex]x = \dfrac{mx_2 - nx_1}{m + n} [/tex][tex]x = \dfrac{(1 \times 5) - (1 \times - 9)}{1 + 1} [/tex][tex]x = \dfrac{5 - ( - 9)}{2} [/tex][tex]x = \dfrac{5 + 9}{2} [/tex][tex]x = \dfrac{14}{2} [/tex][tex]x = 7[/tex]value of y :

Find the slope of the line.
Answer:
0.75
Step-by-step explanation:
I hope this helps!
We must do rise over run to find the slope.
First find 2 points that cross the corner of the grid as shown in the attached image.
Then count how many units up and over it takes to connect the 2 points. For this example, there are 3 up and 4 across.
ΔX = 0 – -4 = 4
ΔY = 1 – -2 = 3
Slope (m) = ΔY/ΔX = 3/4 = 0.75
To solve for slope, it would be [tex]\frac{rise}{run}=\frac{3}{4} =0.75[/tex] is the slope.
