It takes Olive 20 minutes to read 5 pages of her book. At what unit rate is olive reading?

Answers

Answer 1

It is taking Olive 4 minutes to read each page.

20/5 = 4
Hope this helps!

Answer 2

For this case we can find the unit rate in number of minutes per page.

To do this, we divide the total time between the number of pages.

We have then:

[tex]r = \frac {20} {5} \frac {min} {pag}\\r = 4 \frac {min} {pag}[/tex]

Answer:

The unit rate olive is reading is:

[tex]r = 4 \frac {min} {pag}[/tex]

Pool A is filling up slower than Pool B because the slope of the graph for Pool A is less than that of the graph for Pool B.

The slope of the graph tells you the unit rate in gallons per minute. (gallons/minute)

Side Note: Pool A starts with more water in the pool, so even though it is filling more slowly, it may be filled first.

This will prove my answer correct.

The answer to your problem is 3/11

A student answers
90%
of the questions on a math exam correctly. If
sheshe
answers
27
questions correctly, how many questions are on the exam?

Answers

So, we have the percentage she gets which is, 90% and the number of questions she answers correctly, which is 27

To find the number of questions in the exam, make an equation
(90% = [tex] \frac{90}{100} [/tex] = 0.9)
[tex] \frac{90}{100} [/tex] = [tex] \frac{27}{x} [/tex]
cross multiply and equate them
90x = 27 x 100
90x = 2700
divide by 90 on either sides to isolate x in order to find the answer
[tex] \frac{90x}{90} = \frac{2700}{90} [/tex]
90 and 90 cancels out
x = 30
So your final answer will be, there were 30 questions in the exam paper.

Final answer:

To find the total number of questions on the exam, set up a proportion 27 / x = 90% / 100%. Solve for x to find that there are 30 questions on the exam.

Explanation:

To find the total number of questions on the exam, we can set up a proportion. Let's represent the total number of questions on the exam as x.

The proportion would be:

Correctly Answered Questions / Total Questions = Percentage Correct

Substituting the given values:

27 / x = 90% / 100%

Cross multiplying:

27 * 100% = x * 90%

27 = 0.9x

Dividing both sides by 0.9:

x = 27 / 0.9

x = 30

Therefore, there are 30 questions on the exam.

Which number is not in scientific notation? 11 ⋅ 1021 5.7 ⋅ 109 3.1 ⋅ 10−12 1.67 ⋅ 10−5

Answers

11 * 10^21 is not in scientific notation.

Scientific notation requires that the digits part is greater than zero and less than 10 (it cannot be 10).

So, to put that number in scientific notation 11 must be converted to 1.1*10 and 11 * 10^21 is 1.1 * 10 * 10^21 = 1.1 * 10^22.

Note tha 11 * 10^21 is the same that 1.1 * 10^22 but the last is in scientific notation while the former is not.

All the other numbers have the digit part in the range [1,10), so they are in scientific notation.

In triangle ABC, the measure of angle A is , the measure of angle B is , and the measure of angle C is . What is the combined measure of the three angles?

Answers

Final answer:

The combined measure of the three angles in triangle ABC is angle A + angle B + angle C degrees.

Explanation:

The combined measure of the three angles in triangle ABC can be found by summing the measures of angle A, angle B, and angle C.

So, the combined measure of the three angles is angle A + angle B + angle C = angle A + angle B + angle C degrees.

For example, if angle A = 40 degrees, angle B = 60 degrees, and angle C = 80 degrees, then the combined measure of the three angles would be:

40 + 60 + 80 = 180 degrees.

The saving-borrowing-investing cycle generally begins with consumer borrowing to fund their purchases and for seed capital. They then use this capital to invest in their future, which then allows them to bring in more money. They then are able to use income to pay off their loans and to save.

Answers

The statements above are TRUE.
The saving borrowing investing cycle is used by people to achieve financial stability. They cycle is initiated when an individual borrow a sum of money to invest in a business. As time goes on the business begins to yield profits. Part of the profits will be used to repay the borrowed loan. After the repayment, the profits can then be reinvested into the business to generate more profits.

You start out driving from your house to an old friend’s house in a different town, which is 280 miles away. After an hour and a half, you have gone 105 miles.

a) Assuming your speed is constant, find a linear function , which gives the distance from your house (in miles) as a function of time (in hours).

b) Find and interpret D(1).

c) Solve D(t)=280

d) Solve D(t)^3>=140 and interpret the result.

e) Considering the context of this function, what is the domain?

f) What is the range?

Answers

Part A:

Given that after an hour and a half, you have gone 105 miles and that your speed is constant, this means that the slope which represents the speed with which you are driving is given by

[tex] \frac{105}{1.5} =70 \ miles \ per \ hour[/tex]

At 0 hours, he has travelled 0 miles.

The equation of a straight line is given by y = mx + c, where m represent the slope and c is the y-intercept (the value of y when x is 0).

Therefore, a linear function , which gives the distance from the house (in miles) as a function of time (in hours) is given by D = 70t.

Part B:

D(1) is the value of D when t = 1.

D(1) = 70(1) = 70

This means that the distance traveled after 1 hour is 70 miles.

Part C:

D(t) = 280 means the time it takes you to travel 280 miles.

70t = 280

t = 280 / 70 = 4

t = 4.

Part D:

[tex]D(t)^3 \geq 140 \\ \\ \Rightarrow 70t^3 \geq 140 \\ \\ \Rightarrow t^3 \geq \frac{140}{70} =2 \\ \\ \Rightarrow t \geq \sqrt[3]{2} [/tex]

Part E:

The domain is a set of the possible values of the independent variable, from the context of the function, the independent variable is the time it took him for the journey.

Therefore, the domain of the function is [0, 4].

Part F:

The range is the set of the possible values of y, y in the context of the question is the distance travelled at each particular time.

Therefore, the range of the function is [0, 280].

a) D(t)=70t. To find this, consider that we traveled 105 miles in the first 1.5 hours. Since the speed is constant, we simply divide the 105 miles by the 1.5 hours. 105/1.5=70, which tells us we are going 70 mph. To express this as a function, we write the speed of travel (70) times the number of hours (t). Thus D(t)=70t. b) D(1)=70. This means that we traveled 70 miles after one hour. To find this, plug in 1 hour for t and simplify: 70(1)=70. c) t=4. To solve this, set 280=70t and solve for t. 280/70=4. d) t=.0741784872. To solve, take the cube root of both sides. This gives us D(t)=5.192494102. This can be written 70t=5.192494102. Dividing both sides by 70 we get that t=0741784872. e) Domain is t-interval [0,4]. To find this, consider that the trip is 280 miles and we are traveling at 70 mph. Dividing 280 by 70, we see that we will make the trip in 4 hours. Thus our trip starts at t=0 and ends at t-4. f) Range is the D-interval [0,280]. To find this, consider that the domain is [0,4]. d(0)=0 and D(4)=280. Thus the range is [0,280].

A bucket holds c liters of water, but a jar holds 8 liters less. How many times as much water can the bucket hold as the jar?

Answers

The ratio representing how many times as much water the bucket can hold as the jar is [tex]\frac{c}{c-8}[/tex], where c is the capacity of the bucket in liters.

If a bucket holds c liters of water and a jar holds 8 liters less than the bucket, then the jar holds c - 8 liters of water. To find how many times as much water the bucket can hold as the jar, we divide the bucket's capacity by the jar's capacity. This gives us the ratio of the bucket's capacity to the jar's capacity, which is [tex]\frac{c}{c-8}[/tex].

Susan is buying supplies for a party. If spoons only come in bags of 8 and forks only come in bags of 6, what is the least number of spoons and the least number of forks she can buy so that she has the same number of each? asap and tell my how you got the answer please

Answers

it would be 4 packs of spoons and 3 packs of forks. This is because if you multiply 6 times 4 you get 24 and 8 times 3 you will get 24 and then that would be even. If this needs to be further explained please ask me

Answer:

3 bags of spoon and 4 bags of fork.

Step-by-step explanation:

If Susan will buy 3 bags of spoon then, the total spoon is 3 × 8 = 24 spoons

and, If he will buy 4 bags of fork then, the total fork is 4 × 6 = 24 forks.

Thus, for getting equal numbers of spoon and fork he has to buy a minimum of 3 bags of spoon and 4 bags of fork.
