1-i need to mix 25% mineral spirits to the varnish i am using what ratio of spirit to varnish am i using? 2-if i use 240 ml of varnish what quantity of mineral spirits will i need in ml ? 3-Robison's tapestries all measure 1.5m x 1m wide. Express the proportion of the tapestries' heights to width using whole numbers. Give the answer in ration.
Answer:
(1) The required ratio of spirit to varnish is 1:3.
(2) You need 80 ml of mineral spirit.
(3) The ratio of tapestries' heights to width is 3:2.
Step-by-step explanation:
(1) If you need to mix 25% mineral spirit to the varnish, then the solution would contain 25% mineral spirit and 75% varnish.
So, [tex]\frac{spirit}{varnish}=\frac{25}{75}[/tex]
[tex]=\frac{1}{3}[/tex]
Thus, The required ratio of spirit to varnish is 1:3.
(2) If you use 240ml of varnish, then this quantity is 75% of the total solution or ration of varnish to the total solution will be 3:4.
Let [tex]x[/tex] be the quantity of total solution.
Then, [tex]240:x=3:4[/tex].
⇒[tex]\frac{240}{x}=\frac{3}{4}[/tex]
⇒[tex]3x=240*4[/tex]
⇒[tex]x=\frac{240*4}{3}[/tex]
⇒[tex]x=320[/tex]
That is, total solution is 320 ml.
Now, Spirit = Total solution - Varnish
⇒Spirit = 320ml-240ml
⇒Spirit = 80ml
Hence, if you use 240 ml of varnish, you need 80 ml of mineral spirit.
(3) Robison's tapestries all measure 1.5m long and 1m wide. First, we express dimensions in whole numbers by multiplying them by 10.
Then, dimensions are 15m long and 10m wide.
Now, Height : Width = 15:10
⇒[tex]\frac{Height}{Width} =\frac{15}{10}[/tex]
⇒[tex]\frac{Height}{Width} =\frac{3}{2}[/tex]
Hence, the ratio of tapestries' heights to width is 3:2.
Use the two bar graphs to answer the following experimental compound events. What is the
experimental probability of rolling a 2 and spinning 2?
- 6/625
- 4/250
- 24/2500
- 6/50
Answer:
24 / 2500
Step-by-step explanation:
Experimental probability = (number of successes / total number of trials)
For rolling :
Total number of trials = ( 10 + 4 + 8 + 11 + 8 + 9) = 50
Number of times 2 is rolled = 4
P(rolling a 2) = 4 /50
For spinning :
Total number of trials = (8 + 6 + 9 + 11 + 9 + 7) = 50
Number of times 2 is spunned = 6
P(rolling a 2) = 6 /50
Hence,
4 / 50 * 6/50 = 24 / 2500
A weather report stated that the monthly rain amounts for the past three months were 15.82 inches, 17.4 inches, and 9.56 inches.
What is the total amount of rainfall for the three months?
A. 27.12 inches
B. 41.178 inches
C. 42.42 inches
D. 42.78 inches
Answer:
42.78 inches
Step-by-step explanation:
The anount of rainfall for the past three months are
15.82 inches
17.4 inches
9.56 inches
Therefore the total amount of rainfall for the three months can be calculated as follows
= 15.82+17.4+9.56
= 42.78
Hence the total rainfall for three months 42.78 inches

Answer:
not 100% confident but I think this is at least close
Step-by-step explanation:
solve for one variable
1. x-5y=2
x=2+5y
plug this in to another equations and simplify
2. (2+5y)-y=16
2+4y=16
4y=14
y=3.5
this can be plugged in to all other equations to find x
1. x-5(3.5)=2
x-17.5=2
x=19.5
2. x-(3.5)=16
x=19.5
3. 2x-(3.5)=5
2x=8.5
x=4.25
4. x-3(3.5)=4
x-10.5=4
x=14.5

Compute the mean of the following population values:
6, 3, 5, 7, 6.
Answer:
The mean (average) is 5.4 or 5 if you're rounding.
Step-by-step explanation:
Mean is the average of all of the numbers.
Add them up: 6+3+5+7+6 = 27
Divide 27 by the amount of numbers you have(5): 27/5
Solve: 5.4
The mean of the given values 6, 3, 5, 7, and 6 will be 5.4.
What is mean?mean is the average of a data set. Mean gives us the idea of that how much amount of overall data have.
Mean = sum of data / Number of data
For example, if you have marks in 5 subjects like 40,45,44,46,48 then the mean will be
( 40 + 45+ 44 + 46 + 48) /5 = 44.6.
Given the data set;
6, 3, 5, 7, 6
Mean = (sum of data) / (number of data)
Mean = (6 + 3 + 5 + 7 + 6)/5
Mean = 27/5
Mean = 5.4
Hence the mean will be 5.4.

A biology student wanted to determine if using fertilizer would promote plant growth. One hundred plants were randomly assigned to one of two groups: one that used the fertilizer, and one that did not use a fertilizer.
Which of the following is a benefit of having replication in the experiment?
A Having a large number of plants receiving the treatments will allow for a good comparison of the differences in plant growth between the two groups.
B Having a large number of plants receiving the treatments will not allow for a good
comparison of the differences in plant growth between the two groups.
C Replication is not needed in this experiment. One plant receiving each type of treatment is enough to determine if the difference in plant growth is due to the fertilizer.
D Repeating the experiment will allow the student to compare the differences between the plants that received the fertilizer the first time and the plants that received the fertilizer the second time.

Part B: Which function has a greater y-intercept? Justify your answer. (4 points)
(10 points)
Answer
Given: Sorry the images are at the bottom.
To find:
Part A: Write a sentence to compare the slope of the two functions and show the steps you used to determine the slope of f(x) and g(x).
Part B: Which function has a greater y-intercept? Justify your answer.
Solution:
On inspection of values of x and f(x) it is clear that f(x) is a linear function
i.e.
1)Slope of f(x) and y-intercept of f(x):
Convert the function in slope intercept form and calculate the slope.
Slope intercept form:
Here,
Slope of f(x)=1,
y-intercept of f(x)=(0,0)
2) Slope and y-intercept of g(x):
Slope of g(x)=7
Y-INTERCEPT of g(x) =(0,2)
Part A:
Slope of f(x) is 1 and slope of g(x) is 7.
Part B:
g(x) has a greater y-intercept.
