Hi there,

Lets break this problem apart. Madeline is going on a 2-week vacation (14 days) and she brings $368 of her own money as well as $150 from her parents.

First we need to find how much money she has total and that is done by adding up $368 + $150= 518

So she has a total of $518

Next we will determine how she will spend them evenly between 14 days so we divide $518/14 and you get $37.

So Madeline has $37 to spend each day for her 2-week vacation.

Hope this helps! Let me know if you need anything else :)

Kenny had 5/7 more trading cards than lee. After Kenny collected 50% more trading cards, he had 220 more trading cards than lee.

svp [43]

Answer:

Step-by-step explanation:

Let X is the number of cards Kenny has

Let Y is the number of cards Lee has

1. Kenny had 5/7 more trading cards than lee, it means

X = Y + 5/7X (1)

2. After Kenny collected 50% more trading cards, he had 220 more trading cards than lee, it means:

X + 50%X = Y + 220 (2)

So, we solve the 2 equations to find out X and Y

$\left \{ {{X=Y + 5/7X} \atop {1.5X=Y +220}} \right.$

<=> X = $\frac{3080}{17}$ and Y = $\frac{880}{17}$

<=> X ≈181 and Y ≈ 52

HELP ME PLEASE I NEED THIS LOVE U GUYS <33

Answer:

$\huge\boxed{\sf Volume = 384 \ cm^3}$

Step-by-step explanation:

Slant Height = 10 cm

Base Edge = 12 cm

<u>Finding the Height using Pythagorean Theorem:</u>

$\sf c^2 = a^2 + b^2 \\\\Where \ c = 10\ cm , b = 6\ cm [Half of 12] \ and \ a \ is \ height\\\\10^2 = a^2 + 6^2\\\\100=a^2 +36\\\\100-36 = a^2\\\\64 = a^2\\\\Taking \ sqrt \ on \ both \ sides\\\\Height= 8 \ cm$

$\rule[225]{225}{2}$

<u>Now, Finding the volume:</u>

$\sf Volume = a^2 \frac{h}{3}\\\\ Where \ a \ is base \ edge \ and \ h \ is \ height\\\\Volume = (12)^2 \frac{8}{3} \\\\Volume = 144 \frac{8}{3} \\\\Volume = 48*8\\\\\bold{Volume = 384 \ c m^3}$

$\rule[225]{225}{2}$

Hope this helped!

An initial investment of $100,000 at 12% interest is compounded weekly (use 52 weeks in a year). What will the investment be wor

ozzi

Answer:

$3644675.9

Step-by-step explanation:

The initial investment is $100000. The interest rate is 12%.

We are asked to determine the final amount the investment will become after 30 years if the interest is compounded weekly.

The weekly interest rate is $\frac{12}{52} = 0.231$ %.

Assuming 1 year equivalent to 52 weeks.

Hence, using the formula of compound interest the final sum will be

$100000(1 + \frac{0.231}{100} )^{(30 \times 52)}$

= $3644675.9 (Approximate)
