82.5 GH is twice the size of EF and GDH is 3/4 the size. So, 3/4*(110)=82.5

If I remember My geometry correctly
you add GH AND EF then divide 2

Find the missing length to the nearest tenth of a meter of the

marin [14]

Answer:

length of the third side may be either 3.4 m or 2.8 m.

Step-by-step explanation:

Measure of two sides of a right triangle are 1.4 m and the other side is 3.1 m.

then we have to find the measure of third side.

If the third side of the triangle is its hypotenuse then

(Third side)² = (1.4)² + (3.1)²

Third side = $\sqrt{(1.4)^{2}+(3.1)^{2}}$

= $\sqrt{1.96+9.61}$

= $\sqrt{11.57}$

= 3.4 m

If the third side is one of the perpendicular sides of the triangle and 3.1 m is hypotenuse, then

(Third side)² + (1.4)² = (3.1)²

(Third side)²= (3.1)² - (1.4)²

Third side = $\sqrt{(3.1)^{2}-(1.4)^{2}}$

= $\sqrt{9.61-1.96}$

= $\sqrt{7.65}$

= 2.76 m

≈ 2.8 m

Therefore, length of the third side may be either 3.4 m or 2.8 m.

15/4 divide by 5/8. show your reasoning

kompoz [17]

15/4 / 5/8
= 15/4 times 8/5 (you flip the 2nd fraction)
15/4 times 8/5 = 120/20
120/20 can be simplified to 6/1=6
The answer is 6

The sum of two numbers is 25 one number is five less than the other number find the larger number

prohojiy [21]

*NOT MY WORK ITS FROM SOMEONE ELSE WHO ASKED THE SAME PROBLEM*

Answer: x=15, y= 10

Step-by-step explanation:

Answer: x=15, y=10

*Note: x and y are only variables used to solve this problem, but know that the two numbers are 15 and 10.

Step-by-step explanation:

For this problem, we can use system of equations. Let's use x for one number and y for the other.

First Equation:

x+y=25

We get this equation because it states that the sum of the two numbers is 25.

Second Equation:

y=x-5

We get this equation because it says one number (y) is 5 less than the other (x).

Since we have two equations, we can use substitution method to solve.

[distribute 1 to (x-5)]

[combine like terms]

[add both sides by 5]

[divide both sides by 2]

Now that we have x, we can plug it into any of the equations to find y.

[plug in x=15]

[subtract both sides by 15]

Finally, we have our answer, x=15 and y=10.
