7/8 of a cup. If you add 1+1 and then take away 1, you still have 1.

So first, do the addition.
\frac{7}{8} + \frac{7}{8} = \frac{14}{8}
Then, subtract \frac{14}{8} - \frac{7}{8} = \frac{7}{8}

He threw out \frac{7}{8} of a cup.

What is the area of a triangle whose side is 17 meters long​
Lunna [17]

Answer:

125.141

Step-by-step explanation:

Assuming that this is an equilateral triangle, I am going to divide this triangle in half to get a right triangle.

17 is our hypotenuse

17/2 = 8.5, this is one of our legs

The other leg is our height, which we will find.

We use Pythagoras Theorem to find the height/leg: a^{2} +b^{2} =c^{2}

17^{2} -8.5^{2} = 216.75

\sqrt{216.75} = 14.72243186

Now, we use another formula to find the area of the triangle: \frac{Base*Height}{2}

14.72243186 × 17 = 250.2813416

250.2813416 ÷ 2 = <u>125.1406708</u>

there is a beaker of 3.5% acid solution and a beaker of 6% acid solution in the science lab. Mr. Larson needs 200ml of 4.5% acid
disa [49]
Below are the choices:

A. 80 mL of the 3.5% solution and 120 mL of the 6% solution 

<span>B. 120 mL of the 3.5% solution and 80 mL of the 6% solution </span>

<span>C. 140 mL of the 3.5% solution and 60 mL of the 6% solution </span>

<span>D. 120 mL of the 3.5% solution and 80 mL of the 6% solution
</span>
Let fraction of 3.5% in final solution be p. 

<span>p * 3.5 + (1 - p) * 6 = 4.5 </span>

<span>3.5p + 6 - 6p = 4.5 </span>

<span>2.5p = 1.5 </span>

<span>p = 3/5 </span>

<span>3/5 * 200 = 120 </span>

<span>Therefore the answer is B. 120 ml of 3.5% and 80 ml of 6%.</span>

The primeter of a rectangle is 30 inches.If its lengthis three times its length,find the dimensions
Inga [223]
Perimeter = 30 inches
Length = 3x
Width = X

P = 2L + 2W
30 = 2(3x) + 2(X)
30 = 6x + 2x
30 = 8x
30/8 = 8x/8
3 6/8 = 3 3/4 = X
X = 3.75 inches

The width is 3.75 inches and red length would be 3 times as much or 3(3.75) = 11.25 inches.
