A race horse that wins three 3200 meter cup in a time of 200 seconds. what is the race horses Average speed?
Answer:
16 meter per second.
Step-by-step explanation:
A race horse that wins three 3200 meter cup in a time of 200 seconds.
Since in 200 seconds horse can run = 3200 meter
Therefore, in 1 second horse can run = [tex]\frac{3200}{200}[/tex]
= 16 meter/second
1 hour = 3600 seconds
Therefore in 1 hour horse can run = 3600 × 16
= 57,600 meter/hour
The average speed of the horse would be 16 meter per second or 57,600 meter per hour.
What is the equation for a line that passes through the points (-5,-4) and (10,23)?
So you use the point slope stuff.
y-y=m(x-x)
To find the slope, subtract two y values over two x values that are also sibtracted in the same order.
IN this case, you could do (-4 - 23)/-5 - 10
Which is 9/5
So now you plug in the x and y values (doesnt matter which point)
y+4=9/5(x+5)
Make it slope intercept form
y=9/5x-13
How to solve this equation 4(z + 5)=32
Answer:
Z=3
Step-by-step explanation:
divide both sides of the equation by 4
subtract 5 from both sides of the equation
4*(z + 5) = 32
4z + 20 = 32
4z = 32 - 20
4z = 12
z = 12 : 4
z = 3

Solve. Note the equal sign. What you do to one side, you do to the other. Remember to follow PEMDAS.
First, distribute 5 to all terms within the parenthesis
5(w - 1) = (5)(w) + (5)(-1) = 5w - 5
Next, simplify. Combine like terms
5w - 5 - 2 = 5w + 7
5w - 7 = 5w + 7
Next, isolate the variable. Add 7 to both sides, and subtract 5w from both sides
5w (-5w) - 7 (+7) = 5w (-5w) + 7 (+7)
5w - 5w = 7 + 7

Helga and Julie are sisters. Helga is six years younger than twice Julie's age. The sum of Helga's age and Julie's age is 36. Write an equation that can be used to find Julie's age, j. HELPPPPPPPPPPPPPPPPPPPPPPP
Julie's age based on the scenario given cab be obtained by using the equation ; j + 2j - 6 = 36
Let :
Julie's age = j ________(1)
Helga's age = 2j - 6 ____(2)
Sum of their ages = 36
Hence, to find Julie's age, j we can use the equation :
(1) + (2) = 36
j + (2j - 6) = 36
j + 2j - 6 = 36
To find Julie's age, we can use the equation ;
j + 2j - 6 = 36
3j - 6 = 36
3j = 36 + 6
3j = 42
j = 42 / 3
j = 14
Hence, Julie's age is 14 years.

Lori creates the following design for a T-shirt.
Lori found the areas of Triangle 1 and Rectangle 1. Find the areas of the remaining figures.
The area of Rectangle 1 is 8.68 square inches.
The area of Triangle 1 is 6.48 square inches.
The area of Rectangle 2 is ... square inches.
The area of Triangle 2 is ... square inches.
The area of the whole figure is ... square inches.
Solution-
From the figure,
AE = 2.4
EB = 2.8
BC = 11.7
Area of rectangle 1 = 8.68 sq.in
[tex]\Rightarrow FH \times HI=8.68[/tex]
[tex]\Rightarrow EB \times HI=8.68[/tex] (∵ sides of the rectangle 2)
[tex]\Rightarrow 2.8 \times HI=8.68[/tex]
[tex]\Rightarrow HI=3.1[/tex]
Area of Triangle 1 = 6.48 sq.in
[tex]\Rightarrow \frac{1}{2}\times AE \times EG= 6.48[/tex]
[tex]\Rightarrow \frac{1}{2}\times AE \times (EF+FG)= 6.48[/tex]
[tex]\Rightarrow \frac{1}{2}\times AE \times (EF+HI)= 6.48[/tex] (∵ sides of the rectangle 1)
[tex]\Rightarrow EF+3.1= 5.4[/tex]
[tex]\Rightarrow EF=2.3[/tex]
[tex]\Rightarrow BH=2.3[/tex] (∵ sides of the rectangle 2)
[tex]BC = BH+HI+IC[/tex]
[tex]\Rightarrow 11.7= 2.3+3.1+IC[/tex]
[tex]\Rightarrow IC=6.3[/tex]
The area of Rectangle 2,
[tex]=EB\times BH =2.8\times 2.3=6.44\ sq.in[/tex]
The area of Triangle 2,
[tex]\frac{1}{2}\times GI \times IC=\frac{1}{2}\times EB \times IC=\frac{1}{2}\times 2.8 \times 6.3=8.82\ sq.in[/tex]
The area of the whole figure = Area of Triangle 1 + Area of rectangle 1 + Area of Triangle 2 + Area of rectangle 2
= 6.48+8.68+8.82+6.44=30.42 sq.in

An airplane flew at an average rate of 600 miles per hour from Tokyo to Seattle. Because of a strong headwind, the average rate of the return trip was only 480 mph. The round trip took 18 hours. Which equation can be used to determine the time for each leg? 600t = 480t 600t = 18 – t 600t = 480 – t 600t = 480(18 – t)
600t = 480(18 – t) should be it
Answer:
Option D. 600t = 480( 18-t )
Step-by-step explanation:
An airplane flew at an average rate of 600 miles per hour fro Tokyo to Seattle.
Let the airplane travels for t hours so distance covered by the airplane will be = speed × time
= 600t miles
Similarly, average speed in return trip was 480 mile/hour. So distance covered in return trip = speed × time
= 480 ( 18-t ) [ since time taken by plane in round trip was 18. So time taken in return trip will be ( 18-t) ]
Therefore, distance traveled in one trip = distance covered in return trip
600t = 480( 18-t )

send help!!!! Please!! The sum of the measures of the angles from any triangle is 180 degrees. In triangle ABC, angles A and B have the same measure, while the measure of angle C is 45 degrees larger than each of A and B. What are the measures of the three angles?
Let Angle A = X
Since Angle B is the same, angle B is also X
Then angle C = X +45
Add the 3 angles together: X +X +X +45 = 3x+45
That equals 180 degrees:
3x+45 = 180
Subtract 45 from both sides:
3x = 135
Divide both sides by 3:
X = 135/3
X = 45
Angle A = 45
Angle B = 45
Angle C = 45+45 = 90

Joe says that the product of a 4 digit number and a 1 digit number is always a 4 digit number does Joe's statement makes sense?
No, what Joe said isn't necessarily true. Though it is common that the product will be a 4 digit number, because you can use any number, like a large 4 digit number like 9999 or a large 1 digit number like 9, that isn't true. For instance: "9999 x 9" is 89991 which is 5 digits instead of 4 because "9999" is the biggest 4 digit number and "9" is the biggest "1" digit number.

(b) Remember the previous question.
Platinum Gym charges a one-time registration fee of $60, and membership is $20 a month.
(a) Write a expression to represent the membership cost of Platinum Gym for x months.
Let x = months

No. In fact, it will be the same. Waiving the $20 off the one-time fee would give the same amount of one-time payment, 60. Membership and Mandatory equipment maintenance would also add up to $20 a month.

A rectangle has a width of 7.9ft and a perimeter of 27.2 Ft enter the length of the rectangle, in decimal form in the box
Answer:
The length is 5.7 feet.
Step-by-step explanation:
A rectangle has a width of 7.9 feet and a perimeter of 27.2 feet.
Let the length be = x
Perimeter is given by :
[tex]P=2(L+W)[/tex]
We get;
[tex]27.2=2(x+7.9)[/tex]
=> [tex]27.2=2x+15.8[/tex]
=> [tex]2x=11.4[/tex]
Dividing both sides by 2 to get x;
x = 5.7 feet
Hence, length is 5.7 feet.
