Answer:
Change in temperature is +8° C
Step-by-step explanation:
Change in temperature = Final temperature - Initial temperature:
=ΔT = [tex]F_{T} - I_{T}[/tex]
= (- 2° C)- (- 10° C)
= [tex]- 2 + 10[/tex]
∴ Change in temperature = + 8° C
The average grain of salt is 0. 0003 meters wide. Rhinovirus, which causes the common cold, is 0. 00000003 meters wide. How many times wider is a grain of salt than Rhinovirus? Choose the correct answer. A. 1 × 102 times B. 1 × 103 times C. 1 × 104 times D. 1 × 105 times
Number of times a grain of salt is wider than Rhinovirus
= width of average grain of salt / width of rhinovirus
=0.0003 / 0.00000003
=1 × 10^4
Hence, the number of times a grain of salt is wider than Rhinovirus is 10,000 times.
A biologist is studying the growth of a particular species of algae. She writes the following equation to show the radius of the algae, f(d), in mm, after d days:
f(d) = 9(1.04)d
Part A: When the biologist concluded her study, the radius of the algae was approximately 12.81 mm. What is a reasonable domain to plot the growth function? (4 points)
Part B: What does the y-intercept of the graph of the function f(d) represent? (2 points)
Part C: What is the average rate of change of the function f(d) from d = 3 to d = 9, and what does it represent?
Answer:
Step-by-step explanation:
Part A: A reasonable domain to plot the growth function would be from 0 to a reasonable maximum number of days, such as 30 or 60, depending on the duration of the study.
Part B: The y-intercept of the graph of the function f(d) represents the initial radius of the algae when d = 0, which would be 9 mm.
Part C: To find the average rate of change of the function f(d) from d = 3 to d = 9, we can calculate the difference in the function values at these two points and divide it by the difference in the input values. The average rate of change represents the average growth rate of the algae over that time period.

There are many cylinders with a height of 18 meters. Let r
Represent the radius in meters and v represent the volume in cubic meters.
Complete he equation that represents the volume v as a function of the radius r.
Complete the table:
Answer: 18, 72, 288
Step-by-step explanation:
The formula for cylinder volume is V=π r^2 h
Substitute: radius =1 and height =18
V= 18 pi
radius=2
V=72 pi
radius=4
V= 288 pi
Of course, pi appears to already be written there for you :)

Evaluate. 4² - 6 ÷ 2 + 3 =
Answer:
16-3+3= 16 is the answer.
4^2=16 then 6 divided by 2 equal 3 then plus 3= 16
Answer:
16
Step-by-step explanation:
(4²) - (6 ÷2)+3
(4²) - (6 ÷2)+3(16 - 3) + 3
(4²) - (6 ÷2)+3(16 - 3) + 313 + 3
(4²) - (6 ÷2)+3(16 - 3) + 313 + 316
Hence, the correct answer is 16
A spinner with repeated colors numbered from 1 to 8 is shown. Sections 1 and 8 are purple. Sections 2 and 3 are yellow. Sections 4, 5, and 6 are blue. Section 7 is red. Determine the theoretical probability of the spinner not landing on yellow, P(not yellow).
Answer: 0.75 or [tex]\frac{3}{4}[/tex]
Step-by-step explanation: Well there are 2 section colored purple, 2 sections yellow, 3 sections are blue, and 1 section is red.
First lets find the number of favorable outcomes, which would be outcomes with out yellow. 6 out of 8 sections do not have yellow therefore the amount of favorable outcomes is 6.
Now for the total amount of outcomes which is 8.
If we input those numbers in this formula [tex]\frac{Favorable Outcomes}{Total Outcomes}[/tex] so [tex]\frac{6}{8}[/tex] we get 0.75 or [tex]\frac{3}{4}[/tex].

To compare the measures of center of two data sets as a multiple of their measures of variation, their measures of variation must be similar. Why do you think this is true?
To compare two data sets, their variation must be similar because the variation will affect many other variables, including the mean.
What is the variation?When referring to data, the variation is about how much the data variates or the range of the data. For example, if you ask people about their age, the data can spread from 10 years old to 90 years old.
Why is variation important?This affects other variables when analyzing data such as the mean, which implies you can only compare two sets of data if the variation is similar.

Two trains, Train A and Train B, weigh a total of 346 tons. Train A is heavier than Train B. The difference of their weights is 238 tons. What is the weight of each train?
Answer:
A=292, B=64
Step-by-step explanation:
A+B=346 equ 1
A>B
A-B=238 equ 2
A=238+B
input into equ 1
238+B+B=346
238+2B=346
collect like terms
2B=346-238
2B=108
divide both sides by 2
B=54
A=238+B
A=238+54
A=292

Answer:
5)= U(-3,0), M(-1,4), L(-2,0)
6)= R(-4,2), D(-4,5), L(0,2)
Step-by-step explanation:
The x shouldn't change. If this isn't correct, I apologize. But I'm sure I calculated this right.
The coordinates of the figure after a translation of 5 units up is U' ( -3 , 1 ) , M' ( -1 , 4 ) and L' ( -2 , 0 )
The coordinates of the figure after a translation of 3 units up is R' ( -4 , 0 ) , D' ( -4 , 4 ) , L' ( 0 , 3 ) and F' ( 0 , 0 )
What is Translation?A translation moves a shape up, down, or from side to side, but it has no effect on its appearance. A transformation is an example of translation. A transformation is a method of changing a shape's size or position. Every point in the shape is translated in the same direction by the same amount.
A translation in the coordinate plane moves every point on a figure a given distance in a given direction. The position of any point (x, y) on the figure changes to (x + a, y + b), where a and b are real numbers.
Given data ,
Let the translated figure be represented as A
Now , the coordinates of the figure are
a)
The coordinates of the figure are U ( -3 , -4 ) , M ( -1 , -1 ) and L ( -2 , -5 )
And , when the translation is up , the y coordinate increases by d units
The coordinates of the figure after a translation of 5 units up is U' ( -3 , 1 ) , M' ( -1 , 4 ) and L' ( -2 , 0 )
b)
The coordinates of the figure are R ( -4 , -3 ) , D ( -4 , 0 ) and L ( 0 , 0 ) and F ( 0 , -3 )
And , when the translation is up , the y coordinate increases by d units
The coordinates of the figure after a translation of 3 units up is R' ( -4 , 0 ) , D' ( -4 , 3 ) , L' ( 0 , 3 ) and F' ( 0 , 0 )
Hence , the translation is solved

Together, teammates Pedro and Ricky got 2685 base hits last season. Pedro had 281 more hits than Ricky. How many hits did each player have?
Answer:
1,483 is the answer
Answer:
Step-by-step explanation:
Let's say Pedro got x hits
and Ricky got y hits.Given,Pedro and Ricky together got 2685 hits.So, the
equation will be as (x+y)=2685................eq (1)
Given,Pedro had 281 more hits than Ricky.So the equation looks like
x=281+y..........eq(2).
substitute eq(2) in eq(1).We get,
2685=(281+y)+y
2685=281+2y
2685-281=2y
2404=2y
2404/2=y
y=1202
substitute y=1202 in eq(2).We get,
x=1202+281
x=1483
So,Pedro hit 1483 and Ricky hit 1202

Answer:

Step-by-step explanation:
The formula for the area of a trapezoid is (1/2) * (b1 + b2) * height, where b1 and b2 are the different base lengths. In this problem, b1 + b2 = 4 + 13 = 17cm. The height is given in the figure as 4 cm. Thus, the area is (1/2) * (17cm) * (4cm) = 34 cm^2
