B) Karla says that to solve the equation you first multiply by 10 and then add 15.


C) Karla says that to solve the equation you first subtract 15 and then divide by 10.


D) Karla says that to solve the equation you first divide by 10 and then subtract 15.

Answers

the answer is c because you need to isolate the x
The answer is C.

you do the inverse of positive 15, which is negative 15. so put it on both side .

10x +15 =20

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].

To different companies offer online gaming subscriptions. Company A charges $75 upfront and then $20 per month. Company B does not charge an upfront fee, but charges $35 per month. After how many months will the two companies charge the same amount?

Answers

Hello! To solve this equation, let's set it up like this: 75 + 20m = 35m. This is because Company B does not charge an upfront fee, so all you have to do is 35m and Company A charges $75 upfront and then $20 per month, so you do 75 + 20m. First, you subtract 20m from both sides. When you do, you get 75 = 15m. Now, you divide each side by 15 to isolate the m. When you do that, you get 5. Let's plug in the numbers to see what we get. 20 * 5 is 100 + 75 = 175. 35 * 5 =175. 175 = 175. There. The two companies will charge the same amount in 5 months. m = 5.

The number of months when the two companies charge the same amount is 5 months.

Let the number of months when the two companies charge the same amount be represented by x.

Therefore, based on the information given, the equation to solve the question will be:

75 + (20 × x) = 35 × x

75 + 20x= 35x

Collect like terms

35x - 20x = 75

15x = 75

Divide both side by 15

15x/15 = 75/15

x = 5

Therefore, the number of months when the two companies charge the same amount is 5 months.

What is an exponent?

An exponent is a number or letter written above and to the right of a mathematical expression called the base.

Now the given expression is,
10 x 10 x 10 x 10 x 10 x 10

Using the property,

a^a . a^b = a^(a+b)

Thus,

10 x 10 x 10 x 10 x 10 x 10 = 10^(1+1+1+1+1+1)

⇒ 10 x 10 x 10 x 10 x 10 x 10 = 10^7

or, 10 x 10 x 10 x 10 x 10 x 10 = 10⁷

Thus, the required answer for 10 x 10 x 10 x 10 x 10 x 10 as an exponent is 10⁷.

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.

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

Last week, 4.3 inches of rain filled a rain gauge. This week, another 3.375 inches of rain filled the gauge. What was the total amount of rain that filled the rain gauge in two weeks? Enter your answer in the box.

Answers

7.675 inches of rain was the total amount in the two weeks

The rain gauge collected a total of 7.675 inches of rain over the two-week period by adding last week's 4.3 inches to this week's 3.375 inches of rainfall.

This question demands basic understanding of mathematical operations and basic mathematical problem solving.

The question asks for the total amount of rain that filled a rain gauge over a two-week period. Last week, the rain gauge collected 4.3 inches of rain, and this week it collected an additional 3.375 inches. To find the total rainfall over the two weeks, we simply add these two amounts together:

4.3 inches (last week's rain) + 3.375 inches (this week's rain) = 7.675 inches

So, as per the above explaination, the rain gauge collected a total of 7.675 inches of rain over the two-week period.

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.
