1.6 m
3.6 m
9 m
What is the height, in meters, of the tree?
A - 20.24
B - 4.0
C - 32.40
D - 3.8
Answer: B - 4.0
Step-by-step explanation:
[tex]\frac{1.6}{3.6} =\frac{x}{9}[/tex]
(Cross multiply) [tex]3.6x=14.4[/tex]
[tex]\frac{3.6x}{3.6}=\frac{14.4}{3.6}[/tex]

Mr. Aba builds a circular patio with a diameter of 12 feet. He covers the patio with paving stones. The cost of the paving stones is $10.50 per square foot. To the nearest dollar, how much do the paving stones cost.
A. $126
B. $378
C. $1,187
D. $4,748
Answer:
C $1187
Step-by-step explanation:
diameter = 12ft
radius = 6 ft
area = πr²
= 3.14×6×6
= 113.04 ft²
paving stones is $10.5 per ft²
paving stones cost = 113.04×10.5 = 1186.92
; the nearest dollar do the paving stones cost is $1187

Answer:
395.85
Step-by-step explanation:
If the diameter is 12, then the radius must be 6. Following the formula of pi: 2 * pi * radius, our result is 37.7. 37.7 * 10.50 is 395.85
I really hope this helps. My memory of circles and pi isn't the best.

Stephanie ran four laps around the school track in 7 minutes and 30 seconds. How many seconds per lap is that?
Answer:
112.5 seconds
Step-by-step explanation:
Stephanie ran four laps around the school track in 7 minutes and 30 seconds. How many seconds per lap is that?
You need to do convert 7 minutes in to seconds because you cannot do anything to this unless you convert it.
Remember
1 minute = 60 seconds.
So do 7 times 60.
7 × 60
Which is 420 seconds.
Now add the 30 seconds to that.
420 + 30.
Which is 450 seconds.
Now divided 450 by 4.
450 ÷ 4.
Which is 112.5 seconds per lap.

I am doing graphs but I'm struggling a lot with this
Answer:
Stem and Leaf Plot ⇒ Makes it easy to see the largest, smallest and most common data values.
Double Bar Graph ⇒ Compares two sets of data.
Bar Graph ⇒ Shows whether one type of data increases, decreases or neither when another type of data increases.
Scatter Plot ⇒ Shows the frequency of results and trends clearly.
Step-by-step explanation:
Stem and Leaf Plot makes a set of data easy to see and shows common data values together.
Double bar graph is the only graph that focuses solely on 2 sets of data.
Bar Graph description is a bit weird for this one to me but it's the last one (I did others first) and it is close enough.
Scatter plot is best at showing frequency and trends and to see the approximate increase/decrease of many data points.

PLEASE HELP The ratio of athletes in the two teams is 3:2. After 12 athletes move from first team to second, the ratio is 5:4. Find the number of athletes on each team originally.
Answer:
You can use the method of substitution and elimination.
Team A : Team B
3x : 2x
-12 +12
5y : 4y
3x-12=5y ---> (1)
2x+12=4y ---> (2)
12x-48=20y
10x+60=20y
12x-48=10x+60
12x-10x=48+60
= 108
2x=108
x=54
Original number of athletes on Team A = 3(54)
= 162
Original number of athletes on Team B = 2(54)
= 108
a store sells laptops for 720 each. this price is 20 percent more than what it cost the store to buy each of them. before the next model's release, store employees can purchase any remaining laptops at 23% off the store's cost cost. how much would it cost an employee to purchase one of these laptops at the sale?
Answer:
462
Step-by-step explanation:
720 is 120% of the store price so to find the store price, we can muliply by the reciprical or 5/6.
720*5/6= 600
The employee can purchase the laptop at 23% off this price or at 77%. Multiply the price by 0.77 to get the employee price.
600*0.77 = 462
The total cost of the laptop at which an employee purchase is 482 and this can be determined by using the unitary method.
Given :
A store sells laptops for 720 each. This price is 20 percent more than what it cost the store to buy each of them. Before the next model's release, store employees can purchase any remaining laptops at 23% off the store's cost.The following steps can be used in order to determine the total cost of the laptop at which an employee purchase:
Step 1 - The unitary method can be used in order to determine the total cost of the laptop at which an employee purchases.
Step 2 - According to the given data, 720 is the 120% cost at which the store sells. So, the value of the 100% cost is:
[tex]=\dfrac{720}{120}\times 100[/tex]
= 600
Step 3 - Now, the employee can purchase the laptop at a 23% discount that is 77% of the original cost.
Step 4 - So, the total cost of the laptop at which an employee purchase is:
[tex]=\dfrac{77}{100}\times 600[/tex]
= 462

Alex knows 18% of the students surveyed at his school are dropped off by car while 22% walk or ride bikes and the rest ride the bus Which table could represent this information ?
Answer:
The second option.
Step-by-step explanation:
First, the percentages in the "walk" and "ride bike" sections will have to add to 22% as the information says. All of them do except the third option, so that's ruled out.
Next, the rest of the categories have to finish to complete 100%- so they need to add to 78%. Only one of them do, the second with 18% car and 60% bus!

in the addition problem on the right, each letter stands for a digit and different letters stand for different digits. What digits do the letters H,E, and A each represent?
H E
H E
H E
+ H E
____________
A E
Answer:
This problem is easy but I'll demonstrate an approach for simplifying these kind of problems that can be applied to problems of higher complexity.
Key: Notice that you can write AH as 10A + H and HEE as 100H + 10E+E, and thus
AH +A = HEE
10A + H + A = 100H + 10E +E
11A + H = 100H + 11E
11A = 99H + 11E
A = 9H + E
As H can not be 0 (it is the leading digit in HEE), A must be at least and therefore exactly 9 and the problem solves itself from there on.

The value of unknown number would be equal to 1/5
How can we interpret the division?When 'a' is divided by 'b', then the result we get from the division is the part of 'a' that each one of 'b' items will get. Division can be interpreted as equally dividing the number that is being divided into total x parts, where x is the number of parts the given number is divided.
We need to find the unknown number.
A negative divided by a negative is positive, then;
1/7 of x is 1/35
1/35 divided by 1/7
1/7 of x 1/5 = 1/35.
x = 1/5
Therefore, The value is x = 1/5
