$35+0.50()=52 what does this equal

katen-ka-za [31]

Answer:

$(34)$

Step-by-step explanation:

We are looking for what number times .50 makes the equation true.

So, just do backwards equation:

$52 - 35$

$==> 17$

Thus, meaning that what multiplied by 0.50 is equal to 17?

[tex]0.50 * 34[tex]

[tex]==> 17[tex]

the product of two consecutive integers n and n+1 is 42. what is the positive integer that satisfies the situation?

MrMuchimi

$n(n+1)=42 \\
n^2+n=42 \\
n^2+n-42=0 \\ \\
a=1 \\ b=1 \\ c=-42 \\ b^2-4ac=1^2-4 \times 1 \times (-42)=1+168=169 \\ \\
n=\frac{-b \pm \sqrt{b^2-4ac}}{2a}=\frac{-1 \pm \sqrt{169}}{2 \times 1}=\frac{-1 \pm 13}{2} \\
n=\frac{-1 -13}{2} \ \lor \ n=\frac{-1+13}{2} \\
n=\frac{-14}{2} \ \lor \ n=\frac{12}{2} \\
n=-7 \ \lor \ n=6$

The positive integer is 6.
The consecutive integers are 6 and 7.

Movies at the rental store are $3.75 each. Snacks and drinks are $1.89 each. Round each amount to the nearest dollar to estimate

Troyanec [42]

The estimate the total cost to rent 3 movies and buy popcorn, a soda, and a candy bar is $18. option C

<h3>Total cost</h3>

This is the summation of all units cost of items or the results of adding all cost(fixed and variable)

Cost of movies = $3.75

= $4.00 to the nearest dollar

Cost of snacks (drinks, popcorn, candy bars) = $1.89 each

= $2.00 to the nearest dollar

Cost to rent 3 movies and buy popcorn, a soda, and a candy bar.

Total cost = (Cost of movies × number of movies) + cost of popcorn + cost of soda + cost of candy bar

= (4 × 3) + 2 + 2 + 2

= 12 + 2 + 2 + 2

= $18

Therefore, the estimate the total cost to rent 3 movies and buy popcorn, a soda, and a candy bar is $18. option C
