The world record in the long jump is 29 feet and 4 1/2 inches. how many inches short of 10 yards is the record long jump?

1 answer:

3 0

1 yard=36 inches
36×10=360 inches in 10 yards

29 feet and 4 1/2 inches = 352 1/2 inches
360-352.5=7.5 or 7 1/2

the record is 7 1/2 inches short of 10 yards

hope this helped

The sum of three numbers is 88. The first number is 8 more than the second. The third number is 3 times the second. What are the

Sever21 [200]

Answer:

The numbers are 24, 16 and 48

Step-by-step explanation:

For this equation you need to use all the information you have to add in 3 variables, use the information you have to connect them, so you only use one number. You’ll have the second number (x), the first number (x+8) and the third number (3x) now we use all of that to make an equation.

88=x+(x+8)+3x

Now you simplify the equation,

88=5x+8

Now get the x and it’s coefficient alone on one side

80=5x

Now divide both sides so the x is alone

x=16

Since the second number was x you know the second number

the first number is x+8 since x is 16 the first number is 24

The third number is 3 * x so the third number is 48.

So the numbers are 24, 16 and 48

Someone please.. help me in this please I don’t want to fail it..please

igomit [66]

Answer:

So it wants you to first find the mean (average) of the data set, then find the distance everything is from the mean (average).

Step-by-step explanation:

3+5+9+14+16+18= 65

65 divided by the amount of numbers you put in (6) = 10.83 rounded to the nearest hundreth

So now we know the mean (average) now we need to see how far away each number is from the mean (average).10.83-3 is 7.83. 10.83-5 is 5.83. 10.83-9 is 1.83. 10.83-14 is -14.17, but -14.17 would be a normal 14.17 because it wants the absolute value. 10.3-16 is -5.17 (of course keep it as a positive), and finally 10.83-18 is -7.17 as a positive. Now for the mean absolute value of the data they likely mean from 0, so it would be 10.83.

Hope it helped and wasn't too confusing :)

What are the endpoint coordinates for the mid segment of △PQR that is parallel to PQ?

diamong [38]

Answer:

So the end points of the mid segment are:

S $(-3.5,0.5)$

T $(-1,-0.5)$

Step-by-step explanation:

First of all we need to list the co-ordinates of the points of the triangle shown.

P $\rightarrow(-3,3)$

Q $\rightarrow(2,1)$

R $\rightarrow(-4,-2)$

We need to find mid segment of the triangle which is parallel to segment PQ. This would mean we need to find midpoints of segment PR and QR and then join the points to get mid segment.

Midpoint Formula:

$(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})$

Midpoint of PR:

S( $(\frac{-3+(-4)}{2},\frac{3+(-2)}{2})\\\\(\frac{-3-4}{2},\frac{3-2}{2})\\\\(\frac{-7}{2},\frac{1}{2} )$

S $(-3.5,0.5)$

Midpoint of QR:

T $(\frac{2+(-4)}{2},\frac{1+(-2)}{2})\\\\(\frac{2-4}{2},\frac{1-2}{2} )\\\\(\frac{-2}{2},\frac{-1}{2}$

T $(-1,-0.5)$

So the end points of the mid segment are:

S $(-3.5,0.5)$

T $(-1,-0.5)$

By mid segment theorem we know that the line joining midpoints of two sides of a triangle is parallel to the 3rd side.

∴ We know ST is parallel to PQ

Which of the following is a step in bisecting a line segment?

Alexus [3.1K]

Answer:

c. Use a compass to swing an arc on either side of the segment for each endpoint.

Step-by-step explanation:

The steps to constructing a perpendicular bisector are illustrated in the attachment.

Steps 2 and 3 are described by answer choice C.

Other choices

(a) In order to get the arcs to intersect each other, their radius must be more than one half of the segment length.

(b) At no point in the construction are concentric circles involved.

(c) A ruler is not used in any construction. Only a straightedge with no markings will be used for construction.
