How many hundredths equal 4 tenths

Answers

Answer 1
Answer: tenths means 1/10
hunderths means 1/100

how many 1/100 makes 4/10?
1/100 times what=4/10
multiply both sides by 100/1
what=400/10=40

answer is 40 hunderths=4 tenths
Answer 2
Answer: 40 Hundreths=4 Tenths

What ate the coordinates of the fourth point that could be connected with (-8, 0), (1,0), and (1-5)

Answers

Well you can find out by the question it's pretty easy....

you have to find the same x coordinates and then see what the difference is in the y coordinate. For example, (1,0), and (1,-5) the difference is -5. So for (-8,0), and (1,0) your answer would be (8,-5)

3)IF A BALL ROTATES 110 DEGREES IN 8 SECONDS ,HOW MANY DEGREES DOES IT ROTATE IN 32 SECONDS ?
4) IF THE RATIO OF RED ROSES TO YELLOW ROSES IS 4 TO 6 AND THERE ARE A TOTOAL OF 50 ROSES , HOW MANY OF THEM ARE YELLOW?

Answers

1) The best thing to do here is to divide the two weights of the buses and fin out what you need to multiply it by. 
100/50= 2.
Therefore, you've got to multiply the amount of people by 2.
10*2= 20
Therefore, it takes 20 people to pull a 100 ton bus.

2) Here, you should work out what each one is worth. Half of 40 is 20.
one fourth of 20 is 5. Therefore, half of 40 is larger.

3) The best thing to do is to divide 32 by 8, and then multiply the number of degrees by this.
32/8=4
110*4= 440
Therefore, the ball rotates 440 degrees in 32 seconds.

4) the best thing to do is to find what one part is worth- and to do this, you have to add together the amount of roses and divide this by the total roses.
4+6= 10
50/10= 5
The roses are 6 parts yellow, therefore, 6*5= 30, there are 30 yellow roses.

Hope this helps :) 

If cot A = 1.96000 and the acute angle A has to be determined, which one of the following expressionswill give the seconds of the angle?

Answers

cot A = 1.96
tan A = 1 / cot A
tan A = 1 / 1.96
tan A = 0.510204082
A = tan^(-1) 0.510204082
A= 27.03086026°
A= 27° 0.03086026°
A= 27° 0.03086026° x (60' / 1°)
A= 27° 1.8516156'
A= 27° 1' 0.8516156'
A= 27° 1' 0.8516156' x (60" / 1')
A= 27° 1' 0.8516156 x 60"

Then the expression for the seconds is 0.8516156 x 60"

In Option A, we have (-0.00120)/(-0.00141) x 60" = 0.851063830 x 60"
In Option B, we have -0.00141/0.00120 x 60" = -1.175 x 60"
In Option C, we have 0.00806/0.01159 x 60" = 0.695427092 x 60"
In Option D, we have (-0.01159)/(-0.00806) x 60" = 1.437965261 x 60"

Answer: Option A: (-0.00120)/(-0.00141) x 60"
