I sell 1 piece of wood for £1000, however the price is now increased by 5000% how much will I make from 64 pieces of wood?
Answers
Answer: £3200000
Step-by-step explanation:
£1000 is 100%, so 5000% is x50 (5000/100) of £1000 which is £50000. Then 64x50000 is 3 200 000. Therefore you will make £3200000 from 64 piece of wood
What is the solution for the system of equations?
Use the substitution method to solve.
2x+y=20
−5y=−6x+12
Answers
-2x on both sides
y=20-2x
-5(20-2x)=-6x+12
-100+10x=-6x+12
10x+6x=12+100
16x=112
x=7
Substitute x with 7
2(7)+y=20
14+y=20
y=20-14
y=6

Answer:
Yes, there should be a solution.
Step-by-step explanation:
y = -2x + 2; slope is -2.
It is graphed at (0, 2) (1, 0)
You could write this as y = -2x
y = 2x - 6; slope is 2.
It is graphed at (0, -6) (3, 0)
You could write this as y = 2x - 6

The front of Rosie's house is similar in shape to the front of Sparky's doghouse. The base of the doghouse is 6 feet and the height is 5 feet. If the height of Rosie's house is 27.5 feet, what is the length of its base? If necessary, round your answer to the nearest tenth.
1. 22.9 ft pick and awnser!! :)
2. 28.5 ft
3. 33 ft
4. 30 ft
Answers
Answer:
33feet
Step-by-step explanation:
If the base of the doghouse is 6 feet and the height is 5 feet, we can write;
6 feet base = 5 feet height
To get the length of the base if the height is 27.5feet
x feet base = 27.5 feet high
Divide both expressions
6/x = 5/27.5
5x = 6 * 27.5
5x = 165
x = 165/5
x = 33ft
Hence the length of its base will be 33feet

The data in the table is plotted by using a histogram as shown in the diagram attached below.
What is a histogram?
A histogram can be defined as a type of chart that is used to graphically represent a group of data points (statistical information) into user-specified ranges through the use of rectangles.
Generally, the area of each rectangle is directly proportional to the data frequency and its width is equal to the class interval.
Given the following data:
Length of time (t) Frequency.
0 ≤ t < 10 810 ≤ t < 15 1515 ≤ t < 20 1020 ≤ t < 30 11The vertical axis (y-axis) of the histogram would be used to represent the frequency density while the horizontal axis (y-axis) of the histogram would be used to represent the lengths of time spent (in hours) spent by the children in watching Tv last week as illustrated in the diagram below.

The population of deer forest is currently 800 individuals. Scientists predict that this population will grow at a rate of 20 percent per year.
Answers
Answer:
C. 3.8 years
Step-by-step explanation:
Exponential Growth
The natural growth of some magnitudes can be modeled by the equation:
[tex]P(t)=P_o(1+r)^t[/tex]
Where P is the actual amount of the magnitude, Po is its initial amount, r is the growth rate and t is the time.
The actual population of deer in a forest is Po=800 individuals. It's been predicted the population will grow at a rate of 20% per year (r=0.2).
We have enough information to write the exponential model:
[tex]P(t)=800(1+0.2)^t[/tex]
[tex]P(t)=800(1.2)^t[/tex]
It's required to find the number of years required for the population of deers to double, that is, P = 2*Po = 1600. We need to solve for t:
[tex]800(1.2)^t=1600[/tex]
Dividing by 800:
[tex](1.2)^t=1600/800=2[/tex]
Taking logarithms:
[tex]t\log 1.2=\log 2[/tex]
Dividing by log 1.2:
[tex]t=\frac{\log 2}{ \log 1.2}[/tex]
Calculating:
t = 3.8 years

You can buy 3 T-shirts for $24. Write a proportion that gives the cost c of buying 7 T-shirts. $$
Answers
Answer:
3/24 = 7/x
c = $56
Step-by-step explanation:
A percent proportion is just basically a ratio, I could also write this as 3:24 = 7:x, it really doesn't matter. What does matter is that this is considered a percent proportion. Now, to solve a percent proportion, we have this formula.
a/b = c/d
Say b is the unknown value, we would do (a*d)/c, say a was the unknown value, we would do (b*c)/d, Basically, A and D are linked together and B and C are linked together so you take the two values that are linked together first, multiply them together, and divide by the pair that has a partner that is unknown.
