Combine like terms
2z-6z = -4z
-3y-5y = -8y
x-3x = -2x

add them together
-2x - 8y - 4z

viktelen [127]

Answer:

1125.

Step-by-step explanation:

I'm going to work out the answer is grams.

1kg = 1000g

0.225kg of butter = 225g, 225g of sugar, 225g of flour, 0.2kg of eggs = 200g, 250g of berries.

225 + 225 + 225 + 200 +250 = 1125.

Hope that helps. x

Suppose S and T are mutually exclusive events. Find P(S or T) if P(S) = 8/9 and P(T) = 1/10.

blsea [12.9K]

Answer:

$\textbf{$P(S \cap T) = \frac{89}{90}$ }\\$

Step-by-step explanation:

$\textup{Mutually events are events that cannot occur at the same time.}\\\textup{When you toss a coin you get only $head$ or only $tail$ but never both.}\\ \textup{In mathematical terms $P(A) \cup P(B) = 0$, where $A$ and $B$ are mutually exclusive events. }\\\textup{We know the formula:}\\$$ P(A \cup B) = P(A) + P(B) - P(A \cup B) $$\\\textup{When $A$ and $B$ are mutually exclusive, it will simply be:}\\$$ P(A \cup B) = P(A) + P(B) $$\\\textup{Now given:}\\ $P(S) = 8/9$ , $P(T) = 1/10$\\$

$\implies P(S \cup T) = \frac{89}{10}$

What is the length of the hypotenuse of the trim angle ?

Ksju [112]

So for this, you'll be using the pythagorean theorem, which is $leg^2+leg^2=hypotenuse^2$ . In this case, 10 and 24 are the legs, and AB is the hypotenuse. Our equation will be $10^2+24^2=AB^2$

Firstly, solve the exponents: $100+576=AB^2$

Next, combine 100 and 576: $676=AB^2$

And lastly, square root both sides to get $26=AB$

And in short, Line AB is 26 ft, or the first option.
