Answer:

B. is exactly 1 triangle

Step-by-step explanation:

For any given triangle, the sum of the internal angles is $180^{o}$ . Thus from the given question, adding the given angles;

30° + 70° + 80° = $180^{o}$

Therefore, only one triangle can be produced with the given measure of angles. This implies that there is exactly one triangle. So that the correct option is B.

Answer:

[c] The value of w cannot be a negative number.

[d] Substitution is used to replace the variable l with a value of 20.

[e] The subtraction property of equality is used to isolate the term with the variable w.

Step-by-step explanation:

To figure out which steps of the solution are true, let us solve.

2 l plus 2 w equals 62 -> 2l + 2w = 62

----

2l + 2w = 62

2(20) + 2w = 62 <- Substitution is used to replace the variable l with a value of 20.

40 + 2w = 62

2w = 22 <- The subtraction property of equality is used to isolate the term with the variable w.

w = 11

This means that the value of w is not 10 feet so the first option is incorrect. This shape is a rectangle, so the value of w cannot be 0. Since we cannot have a negative measurement, option three is incorrect. This leaves us with the last three options as our answer, shown by the work above.

Live Fund are selling their holding at $5,000 per share.How much would Live Fund receive it they sold half thier holding in Mark

zhannawk [14.2K]

Live Fund receive $\bold{\$2500 A}$ it they sold half thier holding in Marks Brothers.

Solution:

Given: Sale price of Live Fund holding = 5000 dollar

To find: Amount that Live Fund will get if they sell half of their holding in Marks Brothers.

Assume the total number of shares held by Live Fund in Marks Brothers as A

Therfore, half the holdings (or half the number of shares) of Live Fund will be $\frac{A}{2}$ .

Thus, if each share is valued at $\$5000$ , then the total value of the number of shares sold will be as follows,

$\Rightarrow5000\times\frac{A}{2}\text{ dollars }\rightarrow\frac{5000\times A}{2}\text{ dollars }$

$\Rightarrow2500 A\text{ dollars }$

Hence, Live Fund will receive $\$2500 A$

After the addition of an acid, a solution has a volume of 90 milliliters. The volume of the solution is 3 milliliters greater th

11111nata11111 [884]

Answer: $21.75\ milliliters$

Step-by-step explanation:

Let be "x" the original volume of the solution (in milliliters) before the acid was added and "y" the volume of the solution (in milliliters) after the addition of the acid.

Set up a system of equations:

$\left \{ {{x+y=90} \atop {y=3x+3}} \right.$

Applying the Substitution Method, you can substitute the second equation into the first equation and then solve for "x":

$x+y=90\\\\x+(3x+3)=90\\\\4x+3=90\\\\x=21.75$
