Answer:
Do you mean 3/8 times 2/5? It equals 3/20
Step-by-step explanation:
So multiple the top numbers together for the top result and multiple bottom numbers for bottom result. 3 times 2 equal 6, 8 times 5 equal 40. the result is 6 over 40. After simplifying, we have 3 over 20 (dividing both 6 and 40 by 2)

the sum of 2 numbers is 90. the difference is 12. what are the numbers?
Answer:
51 and 39
Step-by-step explanation:
Let's make this into an equation
a + b = 90
and
a - b = 12
Let's merge them
a + b + a - b = 90 + 12
Focus on a for now
2a = 102
a = 51
Now that we have the value of a, we substitute a in any of the 2 equations
51 + b = 90
Subtract 51 from both sides to isolate b
b = 39
We can prove this by adding and subtracting both numbers
51 + 39 = 90
51 - 39 = 12
A box is filled with 9 blue cards, 2 brown cards, and 5 yellow cards. A card is chosen at random from the box. What is the probability that the card is not brown?
Write your answer as a fraction in simplest form.
Answer:
7/8
Step-by-step explanation:
There are 16 cards in total and 2 are brown - this means that 14 are not brown (9 blue cards + 5 yellow cards). Therefore the probability that the card is not brown is 14/16 which is 7/8 in its simplest form.

3. Sleeping Beauty loves to sleep. Every weekday, she makes sure that
she gets the complete 8-hour sleep. However, every weekend, she only
sleeps for 6 hours because she likes to party. What is her total sleeping
hours for a month, given that a month has only 4 weeks?
Answer:
208
Step-by-step explanation:
There are 5 weekdays in a week and 2 weekend days. Since there are 4 weeks, multiply 5 times 4 to get 20 weekdays/month, and 2 times 4 to get 8 weekend days/month. 20 times 8 (the hours she sleeps) is 160 hours, and 8 times 6 is 48 hours. Put together, you get 208 total hours.

Fabian leans a 18-foot ladder against a wall so that it forms an angle of 69° with the
ground. What's the horizontal distance between the base of the ladder and the wall?
Round your answer to the nearest tenth of a foot if necessary.
Answer: 16.12 or 16.1
Step-by-step explanation:
The horizontal distance is equal to 6.45ft.
Using trigonometric ratio SOHCAHTOA,
We have the values of
hypothenuse = 18ftangle = 69°Adjacent = ?Trigonometric RatioUsing trigonometric ratio to solve this problem,
SOHCAHTOA,
we can easily use the cosine of the angle to find the adjacent side.
[tex]cos\theta = \frac{adjacent}{hypothenuse}\\ cos69 = \frac{adjacent}{18}\\ adjacent = 18cos69\\adjacent = 6.45ft[/tex]
From the calculations above, the horizontal distance is equal to 6.45ft.

Complete the statement using the specified property. Multiplication Property of One
1 x w x 16
The multiplication property of one is an identity property
The expression is given as:
[tex]\mathbf{1 \times w \times 16}[/tex]
The multiplication property of one states that:
When one is multiplied by any number or expression, the number or expression remains unchanged.
So, we have:
[tex]\mathbf{1 \times w \times 16 = w \times 16}[/tex]
This property is also referred to as the identity property.
The general rule is represented as:
[tex]\mathbf{1 \times a = a}[/tex]
Examples are:
1 * 2 = 2
1 * x = x
1 * ab = ab

Isaac and his friends wanted to watch a movie on opening night. They bought tickets online for $9 each. They paid an additional $5 handling fee for the order. The cost was more than $150. How many tickets would they have purchased?
Answer:
we can immediately subtract 5$ from the 150$ cost. leaving us with 145$, then we can divide to see if 145 divided by 9 makes sense. it should be around 16.1111 but thats not a valid answer so we round down to 15. 15x9=145

Y = mx + c
M = slope
C = y intercept
In the coordinates (0,3) X value = 0 Y value = 3
Y = (1/2)0 -6 1/2*0 = 0-6 = -6, so no, it isn't a solution.

Dantel is comparing websites for downloading music. One charges a $8 membership fee plus $0.70 per song. Another charges $1.50 per song, but no membership fee. How many songs would Dantel have to buy to spend the same amount at both websites?
Answer:
10 songs
Step-by-step explanation:
Let y = total money spent
x = cost of one song
Since one of the site charges $0.70 per song, we multiply x by 0.7 like this: 0.7x
There is also $8 on top of that to add up to the total cost
y = 0.7x + 8
The other site charges $1.50 per song, so we multiply x by 1.5
There is also no addtional cost
y = 1.5x
1.5x = 0.7x + 8
Subtract 0.7x from both sides
1.5x = 0.7x + 8
- 0.7x - 0.7x
0.8x = 8
Divide both sides by 0.8
0.8x/0.8 = 8/0.8
x = 10
This means Dantel will have buy 10 songs from each site if he wants the same cost from both.
