Answer:

25 grams

Step-by-step explanation:

Three half live

1/2 * 1/2 * 1/2 = (1/2)³ = 1/8

There would be 1/8 of the original amount left

185 * 1/8 = 23.125

Rounded

25 grams

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

Work Shown:

x = smaller number

x+8 = larger number, since it's 8 more than the smaller value

Add up those two expressions, and set the sum equal to 80.

Then solve for x.

x+(x+8) = 80

2x+8 = 80

2x = 80-8 ... subtract 8 from both sides

2x = 72

x = 72/2 .... divide both sides by 2

x = 36

The smaller value is 36 while the larger value is x+8 = 36+8 = 44

Note how 36+44 = 80 to help verify the answer.

Answer:

34.

Step-by-step explanation:

80 = (34 + 8) + x

80 = 42 + x

38 = x

^^ that is an answer, but the question asks for the SMALLER number... Which is up at the beginning of my equation.

I hope this helps. I'm not entirely sure if it's correct, but it's worth a shot... lol

[tex]1st \: day + 2nd \: day + 3rd \: day + 4th \: day = 26\frac{1}{4} \\ 6\frac{1}{3} + 9\frac{1}{2} + 5\frac{1}{4} + x = 26\frac{1}{4} \\ \frac{253}{12} + x = \frac{105}{4} \\ x = \frac{105}{4} - \frac{253}{12} \\ x = \frac{31}{6} = 5\frac{1}{6} [/tex]

well, im assuming u meant quarter, so it would be 1.5 or 1 1/2

Step-by-step explanation:

Answer:

7 units

Step-by-step explanation:

To find the distance between two points, we use the distance formula:

[tex]d = \sqrt{(x_{2}-x_1)^2 + (y_2-y_1)^2 }[/tex]

Plug in what you know.

[tex]d = \sqrt{(-5 - 2)^2 + (-2 - (-2))^2 }[/tex]

Evaluate the double negative.

[tex]d = \sqrt{(-5 - 2)^2 + (-2 + 2)^2 }[/tex]

Evaluate the parentheses.

[tex]d = \sqrt{(-7)^2 + (0)^2 }[/tex]

Evaluate the exponents.

[tex]d = \sqrt{(49) + (0) }[/tex]

Add.

[tex]d = \sqrt{(49)[/tex]

Evaluate the radical.

d = ±7

Since distance cannot be negative, our answer is 7.

The distance between the two points is 7 units.

Hope this helps!

Answer:

Step-by-step explanation:

do this in parts,   take the rectangle in the middle and then the two ends as a whole circle.  :)

the rectangle:   perimeter : 2*10 ft + 2* 6ft= 32ft

the area:   10*6 = 60 [tex]ft^{2}[/tex]

The circle: perimeter: circumference of circle = 2[tex]\pi[/tex]r  or diameter[tex]\pi[/tex] (same thing)

6[tex]\pi[/tex] =18.84955592 ft

area:  area of a circle is  [tex]\pi[/tex][tex]r^{2}[/tex]

[tex]\pi[/tex][tex]3^{2}[/tex] = 28.27433388 [tex]ft^{2}[/tex]

add the two part for the totals

total perimeter is:  32 +18.84955592 = 50.84955592 ft

total area is:   60 + 28.27433388 = 88.27433388 [tex]ft^{2}[/tex]

Actually Welcome to the concept of Equilateral triangles.

Since, from the name itself, equilateral triangles have all sides and angles equal.

Hence the correct answer is

==> D. All sides are the same length.

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

Explanation:

One equation we could solve is

x/2.5 = 30/7.5

Note the x/2.5 has us dividing the vertical sides, while 30/7.5 is the same idea for the horizontal sides. The order is large over small. You could do small over large, but make sure you keep both sides consistent.

Solving for x leads to...

x/2.5 = 30/7.5

x*7.5 = 2.5*30

7.5x = 75

x = 75/7.5

x = 10  (choice A)

There are many other possible equations that lead to the same answer. One other possible equation is x/30 = 2.5/7.5

These proportions are possible due to the fact we have similar triangles.
