You can use Pythagreos theorem to determine it!
Pythagreos theorem is a^2 + b^2 = c^2
1) 4^2 + 4^2 = 6^2
16 + 16 = 36
32 = 36 (So this is not a right-angled triangle )
2) 16^2 + 12^2 = 20^2
256 + 144 = 400
400 = 400 (Sp this is a right-ngled triangle)

What I need to know in this question is the answer

RoseWind [281]

Answer:

1.180

2.50

3.56

Step-by-step explanation:

M<4,M<2 and M<5 have to add up to 180 as a result of being a parallel line.

Making m<2 50 since 46°+84=130, 180-130=50.

Since m<1 is 74 and knowing m<2 is 50 74+50=124 180-124=56 m<3=56

Therefore 1,2,3 =180°

A Chef prepares and evenly divides s ounces of beef stock into 3 smaller pans. The chef uses 8 ounces of beef stock form one of

saw5 [17]

Answer:

Thus, the equation hat correctly represents the number of ounces of beef stock, $s$ , that the chef initially prepares.

⇒ $\frac{s}{3}-8=34$

The total number of ounces of beef stock = 126

Step-by-step explanation:

Given:

Total ounces of beef stock = $s$

The chef divided the beef stock evenly into 3 smaller pans.

The chef then uses 8 ounces from one of the smaller pans.

Ounces of beef stock left in the smaller pan = 34

Solution:

Total ounces of beef stock = $s$

Ounces of beef stock in each smaller pan = $\frac{s}{3}$

Ounces of beef stock used by the chef from the smaller pan = 8.

The ounces of beef stock left in the smaller pan will be given as:

⇒ $\frac{s}{3}-8$

Ounces of beef stock remaining in smaller pan = 34

Thus, the equation hat correctly represents the number of ounces of beef stock, $s$ , that the chef initially prepares.

⇒ $\frac{s}{3}-8=34$

Solving for $s$ .

Adding 8 both sides.

⇒ $\frac{s}{3}-8+8=34+8$

⇒ $\frac{s}{3}=42$

Multiplying both sides by 3.

⇒ $3\times \frac{s}{3}=42(3)$

∴ $s=126$

Thus, total number of ounces of beef stock = 126

Which set of numbers is correctly ordered from least to greatest?

kakasveta [241]

Answer:

First option.

===========================

Step-by-step explanation:

The given set of numbers are:

$\frac{24\pi }{5} \ , \frac{63}{4} \ , 15.758 \ , 956\sqrt{e}$

And it is required to order the set of numbers correctly from least to greatest.

The easiest way is to convert all numbers to decimal and comparing it.

$\frac{24\pi }{5} =15.0796\\\frac{63}{4}=15.75\\ 956\sqrt{e} =1,576.178$

So, The order from least to greatest is as following

$\frac{24\pi }{5} \ , \frac{63}{4} \ , 15.758 \ , 956\sqrt{e}$

So, the correct answer is first option.

Christopher needs to buy wooden boardes to build a box that is 12 inches long, 6 inches wide, and 8 inches high. How many square

anzhelika [568]

Answer:

432 in²

Step-by-step explanation:

To Obtian the square inches of wooden boards required :

Area of box = 2(l * w) + 2(l * h) + 2(h * w)

Length = 12 ; width = 6 ; height = 8

Hence,

Area of box = 2(12 * 6) + 2(12 * 8) + 2(8 * 6)

Area of box = 2(72) + 2(96) + 2(48)

Area of box = 432 in²
