An oak tree casts a shadow that is 16 yards long. A wooden column near the oak tree casts a
shadow that is 8 yards long. If the oak tree is 12 yards tall, how tall is the wooden column?
Write your answer as a whole number or a decimal. Do not round.
Answer:
Wooden Column: 8 yards x
________ = ________, solve for x
Oak tree: 16 yards 12
8/16 = x/12

At 4:00 in the afternoon you notice that the kitchen sink is leaking. Unfortunately,
you have a major test to study for and you won't be able to repair it until 3:30 PM
the next day. Your sister decides to put an empty cup under the leak to determine
how fast it is dripping so that she can tell you how much water is going to be
wasted if you wait until tomorrow to fix it. After 1.5 hours she has collected a
total of 43 cup of water. How much water does she tell you is going to be wasted?
In 1.5 hours, she got 43 cups of water (assuming they're all full)
So, in an hour, she got 43 : 1.5 = 86/3 cups
From 4 in the afternoon to 3:30pm next day, that is 23 hours 30 minutes. (full day - 30 min)
Convert 23 hours 30 minutes to 23.5 hours
So, she will tell you that 86/3 x 23.5 = 2021/3 cups of water is gonna be wasted. (if you need to round it's 674 cups.)

How tdo cells communicate through chemical signaling.
Answer: Cells typically communicate using chemical signals. These chemical signals, which are proteins or other molecules produced by a sending cell, are often secreted from the cell and released into the extracellular space. There, they can float – like messages in a bottle – over to neighboring cells.

what is 2/3 as many as 18
Answer:
12
Step-by-step explanation:
Multiply 2/3 and 18. Since it a whole number, convert it to a fraction by putting it over a denominator of 1. When multiplying fractions, calculate numerator times numerator, then denominator times denominator. Multiply 2/3 x 18/1 to get 36/3.
Simplify the resulting fraction as needed by dividing it by the common denominator. The common denominator of 36 and 3 is 3. Diving 36 and 3 by 3 gives you a fraction of 12/1, which is the same as 12. Thus, two-thirds of 18 is 12.
[tex]\frac{2}{3}*\frac{18}{1}[/tex]
[tex]=\frac{36}{3}[/tex]
[tex]=\frac{12}{1}[/tex]
[tex]=12[/tex]

You had $50. You spent 10% of the money on clothes, 20% on games, and the rest on books. How much money was spent on books? Remember-what does OF mean?
Answer:
$35
Step-by-step explanation:
10% + 20% = 30%
You spent 30% of the $50 clothes and games.
You spent the rest on books.
100% - 30% = 70%
You spend 70% on books.
70% of $50 = 0.70 × $50 = $35
Answer: $35
Answer:
35
Step-by-step explanation:
x/50=70/10 cross multiply and then divide 3500 by 100 which equals 35 which would be $35 which is 70% of $50

Find the area of this figure. Round your answer to the nearest hundredth. Use 3.14 to approximate Pi.
Given:
Radius of circle = 3 ft.Height of triangle = 4 ft.1. Finding the area of the semi-circle:Since the area of the semi-circle is the area of half the circle, the formula of finding the area of the circle will be divided by 2 to find the area of the semi-circle.
This means that:
Area of semi-circle = Area of circle/2 = πr²/2Now, let's substitute the radius into the formula to find the area.
Substituting the radius into the equation:
Area of semi-circle = πr²/2 => Area of semi-circle = (π)(3²)/2Simplifying the RHS:
=> Area of semi-circle = (π)(3²)/2 => Area of semi-circle = (π)(9)/2Substituting π as 3.14:
=> Area of semi-circle = (π)(9)/2 => Area of semi-circle = (3.14)(9)/2Simplifying the RHS:
=> Area of semi-circle = (3.14)(9)/2 => Area of semi-circle = (1.57)(9)=> Area of semi-circle = 14.132. Finding the area of the triangle:Before we find the area of the triangle, we need to know the base, which is the diameter of the semi-circle.
Diameter = 2(Radius)=> Diameter = 2(3)=> Diameter = 6 feetNow, let's find the area of the triangle.
Area of triangle = 1/2 x 6 x 4=> Area of triangle = 3 x 4=> Area of triangle = 12 ft²3. Finding the area of the figure:The area of the figure is basically the sum of the semi-circle and the triangle.
=> Area of figure = Area of triangle + Area of semi-circle=> Area of figure = 12 + 14.13=> Area of figure = 26.13 ft²Thus, the area of the figure is 26.13 ft².

Elijah has a bag that contains pineapple chews, strawberry chews, and peach chews. He performs an experiment. Elijah randomly removes a chew from the bag, records the result, and returns the chew to the bag. Elijah performs the experiment 59 times. The results are shown below:
A pineapple chew was selected 15 times.
A strawberry chew was selected 26 times.
A peach chew was selected 18 times.
Based on these results, express the probability that the next chew Elijah removes from the bag will be pineapple chew as a percent to the nearest whole number.
Answer:
25%
Step-by-step explanation:
Total number of drawings: 59
Drawing a pineapple chew: 15
p(pineapple chew) = 15/59 = 0.2542 = 25%
Using it's concept, it is found that there is a 25% probability that the next chew Elijah removes from the bag will be pineapple chew.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
In this problem, the experiment was performed 59 times, and 15 of them resulted in a pineapple being selected, hence the probability is given by:
p = 15/59 = 0.25 = 25%.

does y+x=1 show direct variation
Answer:
No
Step-by-step explanation:
Equations with direct variation follow the form y= kx, where k = constant of proportionality.
To find out if y + x = 1, we need to isolate y by itself.
Step 1: Subtract x from both sides.
[tex]y+x-x=1-x[/tex] [tex]y=-x+1[/tex]As you can see, y + x = 1 does not show direct variation.

The length of a rectangle is 4 cm greater than its breadth. if the perimeter of the rectangle is 32cm what is the length and width
Given :
The length of a rectangle is 4 cm greater than its breadth. The perimeter of the rectangle is 32cm.To Find :
The Length and width of the rectangle.Solution :
We know that,
[tex]\qquad{ \bold{ \pmb{2(Length + Width) = Perimeter}}}[/tex]
So,
Let's assume the length of the rectangle as x cm. Then the breadth will become (x – 4) cm.Now, Substituting the given values in the formula :
[tex] \qquad \dashrightarrow{ \sf{2[x + (x-4)] = 32}}[/tex]
[tex]\qquad \dashrightarrow{ \sf{2(x + x-4) = 32}}[/tex]
[tex]\qquad \dashrightarrow{ \sf{2(2x-4) = 32}}[/tex]
[tex]\qquad \dashrightarrow{ \sf{4x-8= 32}}[/tex]
[tex]\qquad \dashrightarrow{ \sf{4x= 32 + 8}}[/tex]
[tex]\qquad \dashrightarrow{ \sf{4x= 40}}[/tex]
[tex]\qquad \dashrightarrow{ \sf{x= \dfrac{40}{4} }}[/tex]
[tex]\qquad \dashrightarrow{\pmb{ \bf{x= {10} }}}[/tex]
Therefore,
Length = 10 cmWidth = (10 – 4) = 6 cmAnalyzing the map look at the map, why do you think general Washington and his men went to valley forge during the siege of philiadelphia
