Answers

Answer:

100%

Explanation:

To find percent increase, you first have to find the difference between the two values.

16 - 8 = 8

Next, you divide this new answer by the original value.

8 ÷ 8 = 1

Finally, you multiply by 100 to find your percent increase.

1 × 100 = 100%

i’m pretty sure it’s 100

Does 6/10+8/100 = 14/10 or 68/10??

Answers

Answer:

The answer is 68/100 or 17/25

Step-by-step explanation:

To solve this problem, you need to find common denominators. In this equation, the easiest way to do this is to make both fractions have a denominator of 100. 8/100 is already in the proper denominator, and 6/10 can be multiplied by 10 to get 60/100. After adding, you get 68/100 which simplifies to 17/25

Answers

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 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?

Answers

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.

Complete he equation that represents the volume v as a function of the radius r.

Complete the table:

Answers

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 :)

−7°C, what was the temperature at 2:00 am?

Answers

Answer:

-3.90

Step-by-step explanation:

1) 1.55+1.55 =3.10

2) -7+3.10= (-3.90)

The answer is -3.9 degrees Celsius because 1.55+1.55=3.10 (We do this because 1h= +1.55 so 2h = +3.10) and then we do -7+3.10= 3.90 degrees Celsius (we do this because we do the initial temperature plus the temperature risen in 2 hours)

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

Answers

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.

"Evaluate the expression.
78 - 2^4 ÷ (14 - 6) x 2"
please explain how you get your answer.
thanks

Answers

Answer:

equal to 74

Step-by-step explanation:

To evaluate the expression, we will follow the order of operations (PEMDAS):

Start with the exponent: 2^4 = 16Next, evaluate the division: 14 - 6 = 8Then, divide 16 by 8: 16 ÷ 8 = 2Next, multiply the result by 2: 2 x 2 = 4Finally, subtract 4 from 78: 78 - 4 = 74

So the expression 78 - 2^4 ÷ (14 - 6) x 2 is equal to 74.

Let’s use pemdas or bodmas
Let’s solve separately first

2^4 = 2’s power 4 = 2*2*2*2 = 16
14-6 = 8
2” = 2*2 = 4

78 - 16 / 8 * 4
= 78 - 2 * 4
= 78 - 8 = 70

Answers

Answer:

34 cm^2

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

Answer: hope this helps ♡

Jack will be twice as old as his sister in -8 years.

Step-by-step explanation:

If Jack could age backwards, he would be twice as old as his sister in -8 years.

Jack = 12

Amy = 2

2*2 (Amy) = 4

12 - 8 = 4  (we got 8 by subtracting amy's age from jack's age: 12-2=8)

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?

Answers

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

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?

Answers

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.
