Answer:

Step-by-step explanation:

We know the following:

$OE=5\\\\FG=4\\\\EF=8\\\\$

so the segment EF is equal to

$EF=EG+GO+OF\\\\$

and here we can do a trick :)

$EF=(EG+GO)+GO+(OF+OG)-2GO\\\\$

you see it's the same

$EF=EO-GO+FG\\\\$

now we plug the values given

$8=5-GO+4\\\\8=9-GO\\\\GO=9-8\\\\GO=1$

so it's option A

Given:

A(16, 4)

B(34, 40)

Line segment AB partition in the ratio 1 : 5.

To find:

The coordinate of a point that partitions AB.

Solution:

Section formula:

$$P(x,y)=\left(\frac{m x_{2}+n x_{1}}{m+n}, \frac{m y_{2}+m y_{1}}{m+n}\right)$

Here $x_1=16, y_1=4, x_2=34, y_2=40$ and m = 1, n = 5

$$P(x,y)=\left(\frac{1\times 34+5 \times 16}{1+5}, \frac{1\times 40+5 \times4}{1+5}\right)$

$$P(x,y)=\left(\frac{ 34+80}{6}, \frac{40+20}{6}\right)$

$$P(x,y)=\left(\frac{ 114}{6}, \frac{60}{6}\right)$

$$P(x,y)=(19, 10)$

The coordinate of point that partitions the segment AB is (19, 10).

A right square pyramid is shown. The height of the pyramid is 6 units. The distance from the center of the base of the pyramid t

elena-14-01-66 [18.8K]

Answer:

AD is 6.5 units

Step-by-step explanation:

Find the diagram attached.

From the diagram, you can see that the dotted triangle is a right angled triangle with side AD as the hypotenuse.

To get AD, we will use the pythagoras theorem as shown;

Hyp² = Opp² + Adj²

AD² = 6²+2.5²

AD² = 36 + 6.25

AD² = 42.25

AD = √42.25

AD = 6.5

Hence the measure of length segment AD is 6.5 units

How many, Inch cubes fit into a rectangular prism that measures 4 Inches long, 5 Inches wide, and

kramer

780 (or c)

I think this is correct because 4 x 5 = 20 x 5 = 100 and 100 x 5 = 500

500 + 280 = ????

6 - 2/3 (x+5) = 4x solve algebraically for the exact value of x

luda_lava [24]

Answer:

x = 2

Step-by-step explanation:

1 - Rewrite

6 - 2/3 (x+5) = 4x

2 - Distribute

6 - 2/3x + 10/3 = 4x

3 - Combine like terms and get x alone

6 10/3 - 2/3x = 4x

+2/3x +2/3x

6 10/3 = 4 2/3x

------------------------------- Convert to decimals

6.3333333333.... = 4.333...x

-------------------------------- Divide both sides by 4.33...x

2 = x

Hope this helps :)
