Use properties to find the sum or product 8×51

Answers

  8 ×51 = 8(50+1) = 8×50+08*1=400 + 08=408

Answer:

8 \cdot 51 = 408

Step-by-step explanation:

use properties to find the sum or product 8×51

To use properties lets break 51 as 50 +1

8 times 51

8(50+1)

Now we use distributive property , Using this property we distribute 8 inside the parenthesis

8 times 50 is 400

8 times 1 is 8

400+8 = 408

So8 \cdot 51 = 408

Tina described four triangles as shown below: Triangle A: All sides have length 12 cm.
Triangle B: Two sides have length 10 cm, and the included angle measures 60°. Triangle C: Base has length 15 cm, and base angles measure 40°.
Triangle D: All angles measure 60°.

Which triangle is not a unique triangle? Triangle A Triangle B Triangle C Triangle D

Answers

Answer:

Triangle D is not a unique triangle.

Step-by-step explanation:

Triangle A:  All sides have length 12 cm.

such a triangle will be a unique triangle and it will be an equilateral triangle.

Triangle B: Two sides have length 10 cm, and the included angle measures 60°.

Such a triangle will also be unique because with the help of the given angle measure and and the angles opposite to equal sides are equal we can find the measure of those two angles.

and hence we can construct a triangle with the help of these information.

Triangle C:  Base has length 15 cm, and base angles measure 40°.

Such a triangle will also be unique as a unique triangle could be constructed with the help of these information.

Triangle D: All angles measure 60°.

Such a triangle will be an equilateral triangle but we can't say it will be unique as we can construct infinite number of triangles with different side lengths.

Hence such a triangle is not unique.

Answer:

C

Step-by-step explanation:

If you use substitution,  you will figure out that x=350-y, and 3x=1050-3y. If you plug this into the equation, 1050-3y+7y=2050.

Simplifying, we get 1050+4y=2050, and 4y=1000.

Divide each side by 4 to get y=250.

What is 62 1/2% as fraction

Answers

The 62.5% in the fraction is (5)/(8).

Given that,

  • The given number is 62.5%.
  • We need to transform it in the fraction form.

Based on the above information, the calculation is as follows:

= 62.5\n\n=62.5/ 100\n\n=625/ 1000\n\n=25/ 40\n\n=5/ 8

Therefore, we can conclude that The 62.5% in the fraction is (5)/(8).

it is 5/8 as a fraction

Is 36 yards 2 feet greater than less then or equal to 114 feet 2 inches

Answers

It would be less then because, first we need to convert yards into feet which the formula for doing that is 3 feet per yard so if you have 36 yards you would take 36*3=108 then you would add 2 feet because there are 2 extra feet to add on to the end of this question. Like so 108+2=110 then we see which one is bigger 114<110 does not work out and 114=110 is no true but 114>110 is correct and works out to be true therefore your answer is 114 and 2 inches is bigger then  26 yards and 2 feet.

Enjoy!=)
less than because you make 144 feet into yards and you get 48 and then turn 2 feet from the first distance into inches and your inequality would be this
36yards24inches<48yards2inches
