Question

The side lengths of a triangle are 7, 24, and 25. Is this triangle a right triangle? A) yes
b) no
c) not enough information â€‹

Solution 1

**Answer:**

yes

**Step-by-step explanation:**

for it to be a right triangle you should be able to add two of the sides and it be greater than the third side. 7 + 24 > 25

24 + 25 > 7

7 + 25 > 24 therefore it is indeed a right triangle

Solution 2

Yes. Hope this helps :)

Question

-9/4 v + 4/5 = 7/8 v=? step by step need help asap please

Solution 1

-9/4v + 4/5 = 7/8; First, you subtract 4/5 from each side to have variable v on a side and numbers on the other: -9/4v = 7/8 - 4/5; -9/4v = 35/40 - 32/40; -9/4v = 3/40; Then you divide each side to get the variable v alone on a side, and one number on the other: V= (3/40) / (-9/4); Dividing to fractions is equal to multiplying the first one by the inverse of the second: V= (3/40) * (-4/9); V= -12/360; V= -1/30; You can re-check your answer (very important): (-9/4)*(-1/30)+4/5=7/8; The answer has been approved. Hope this helps! :)

Question

A pipe is leaking in the school bathroom. It has leaked 3 gallons of water in 6 hours.
COP=

Solution 1

**Answer:**

COP [Constant of Proportionality or k] = Â½

**Step-by-step explanation:**

y = kx.

y = dependent variable [vertical].

x = independent variable [horizontal].

y in this case is the gallons and x in this case is the hours.

Therefore

#gallons = 1/2 #hours

y = 1/2x

k = 1/2

____________

This is because at a rate,

the pipe leaks at 1/2 or 0.5 gallons per hour.

Question

Hi pls help : x^2-8x-48=0 (this is algebra btw)

Solution 1

**Answer:**

x=âˆ’4 or x=12

**Step-by-step explanation:**

Step 1: Factor left side of equation.

(x+4)(xâˆ’12)=0

Step 2: Set factors equal to 0.

x+4=0 or xâˆ’12=0

x=âˆ’4 or x=12

Solution 2

**Answer:**

-7 ?

**Step-by-step explanation:**

x^2 - 8x -48=0

add both x

-7x -48=0

Â Â +48. Â +48

-7x = 48

----- Â -----

-7 Â Â Â Â -7

x = -7

Question

Can anyone please explain to me how Equivalent Expressions work?

Solution 1

**Answer:**

Equivalent expressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value(s) for the variable(s). Examples.

**Step-by-step explanation:**

Question

Find the Area & Circumference of a circular pizza with a diameter of 22.0cm.

Solution 1

**Answer:**

**Circumference = 69.14cm****Area = 380.29cmÂ²**

**Step-by-step explanation:**

**Circumference. **

Circumference of a circle is calculated by the formula:

= Pie * diameter

= Ï€ * diameter

= 22/7 * 22

**= 69.14 cm **

**Area **

Area of circle:

= Pie * radius Â²

Radius = diameter/2

= 22/2

= 11 cm

Area = 22/7 * 11Â²

= 22/7 * 121

**= 380.29 cmÂ²**
