Answer:

12*3/8 we just turn the 12 into a improper fraction and multiply the top and the bottom with 3/8 top and bottom so

12/1*3/8

12*3=36

1*8=8

so 36/8 the answer is

a 28 inch piece of steel is cut into three pieces so that the second piece is twice as long as the first piece, and the third pi

klasskru [66]

Where x is the length of the first piece
$x + 2x + 6x + 1 = 28 \\ \\ 9x = 27 \\ \\ x = 3$
so the first piece is 3 inches, the second is 6 inches and the third is 19 inches

A class of 40 students elected a class president. There were 12 votes for Candidate A, and 18 votes for Candidate B.

Helen [10]

Hey there, Bulgogi!

The correct answer will be the first one since [I'm assuming] you know that to calculate the percentage of something, it's the amount of that something divided by the total amount but since only 30 students voted [12+18] multiplied by 100.

So, we are calculating the percentage on votes and 12 students voted for Candidate A so our Numerator will be 12 and our Denominator will be the total amount of student who voted, so 30 [or 12+18]

Once put into a fraction, we will get $\frac{12}{12+18}$ which would be equals to 2/5 or 0.4. Now we multiply by 100 and we get a total of 40% for Candidate A.

Thank you for using Brainly.
See you soon!

Answer:

27.5cm^2

Step-by-step explanation:

you can cut the triangle to make two right triangles

so 11 is the height and the width is 2.5 since your cutting the triangle in half

so 11x2.5=27.5 since its a right triangle you have to divide by two 27.5/2=13.75

that's the answer for one of the triangles now multiply it by two since you need the two right triangle to make the other triangle so the answer is 27.5

A tennis player moves in a straight-line path as shown in the figure below. find her average velocity in the following time inte

Andreyy89

To find the average velocity in a velocity-time graph at a particular interval, simply determine the gradient at that particular interval.

a. average velocity= 4/1 
= 4m/s 

b. average velocity from 1 to 2.5s= 6/(2.5-1) 
= 4m/s 

average velocity from 2.5 to 4.0s= 0m/s 

average velocity from 0 to 4.0s= (4+0)/4 
= 1m/s 

c. average velocity from 1.0 to 4.0s= (4/3)m/s 

average velocity from 4.0 to 5.0s= 2/1 
= 2.0m/s 

average velocity from 1.0 to 5.0s= ((4/3)+2)/4 
= (5/6)m/s 

d. average velocity from 0 to 4.0s= 1.0m/s 

average velocity from 4.0 to 5.0s= 2.0m/s 

average velocity from 0 to 5.0s= (1.0+2.0)/5 
= (3/5)m/s
