Answer:

x = 15

Step-by-step explanation:

From the above diagram, we can see that the right angled triangle has been split into two by drawing a line from the altitude.

This would really in the following ratios or proportions below

25 : x = x : 9

25/x = x/9

Cross Multiply

x² = 25 × 9

x² = 225

x = √225

x = 15

Using the following image, if you EG = 59, what are x, EF, and FG.

Harman [31]

Answer:

$x=6\,\,units\,,\,EF=34 \,\,units\,,\,FG=25\,\,units$

Step-by-step explanation:

Given: $EG =59 \,\,units$

To find: $x,EF,FG$

Solution:

From the image, $EG=EF+FG$

Put $EF=8x-14\,,\,FG=4x+1\,,\,EG=59$

$8x-14+4x+1=59\\12x-13=59\\12x=59+13\\\\12x=72\\x=\frac{72}{12}=6$

$EF=8x-14=8(6)-14=48-14=34\\FG=4x+1=4(6)+1=24+1=25$

Therefore,

$x=6\,\,units\,,\,EF=34 \,\,units\,,\,FG=25\,\,units$

Please help need to get to 80%

Shalnov [3]

Answer:

$\frac{1}{6}$

Step-by-step explanation:

First, start by converting 4 feet to inches. Note that 1 foot = 12 inches.

Set up a unit converter:

$4\ ft(\frac{12\ in}{1\ ft})$

The ft cancel out leaving us with:

$4*12\ in=48\ in$

Now, we can set up a scale factor...

$\frac{drawing}{real\ length}=\frac{8}{48}=\frac{1}{6}$

Given x=-3, y=6, and z=-4 3x-2y+z=

Murljashka [212]

Answer: -25
Since x=-3, y=6, and z=-4 you have to plug those numbers into the corresponding varibale in the equation. So 3x becomes 3(-3) because x=-3, 2y becomes 2(6) because y=6 and z becomes just -4. The whole equation comes to 3(-3)- 2(6)+(-4)= -25

loris [4]

Take 14,350 x .28 = 4,018 of them were high school students

The total attended were 14,350 people. 28% of them were high school students, so it's a simple multiplication problem to find the number of high schoolers.
