Answer:

$3.10

Step-by-step explanation:

Money earned by mowing 5 lawns (income) = $4.70 x 5 = $23.50

Cost of filling 3 tanks (expenditure) = $6.80 x 3 = $20.40

Profit = income - expenditure

         = $23.50 -  $20.40

        = $3.10

Answer:

74%

Step-by-step explanation:

Ive done this before

Step-by-step explanation:

To find a ratio, you have to divide a next terms with before terms.

A1 = 35/2

A2 = 7

ratio = A2 ÷ A1

ratio = 7 ÷ 35/2

ratio = 7 × 2/35

ratio = 14/35 = 0,4

Ratio = 0,4

Answer:

option 1

Step-by-step explanation:

Given (x, y ) lies on the graph of f(x) , then the corresponding point on the graph of its inverse is (y, x ) , so

If point (- 7, 5 ) lies on the graph of f(x) , then

(5, - 7 ) lies on the graph of its inverse

Answer:

  a. reflection across line l

  b. see attached

  c. no

Step-by-step explanation:

The easiest transformation to put figure H' back where figure H is will be "reflection across line l". A reflection back across the same line of reflection puts the figure in its original location.

__

The attached figure shows the requested translation and labeling. The dim dotted figure is the original translation of H along vector EF. The reflection of that across line l is marked H''' as required.

__

No, figures H'' and H''' are not in the same location. One only needs to look at the diagram to see this.

In general the order of translation and reflection makes a difference. This means reflection of H to H', then translation to H'' will have a different result than translation of H to H(shadow), then reflection to H'''.

Answer:

8+h3-4

Step-by-step explanation:

10(h+2)−2h when h = 9.

The relation between the expression at h = 9 will be;

⇒ 7 + h² - 5 < 10 (h + 2) - 2h

What is substitution method?

To find the value of any one of the variables from one equation in terms of the other variable is called the substitution method.

Given that;

The expressions are,

⇒ 7 + h² - 5

⇒ 10 (h + 2) - 2h

Now,

Solve the expression for h = 9 and find the relation between them as;

Since, The expressions are,

⇒ 7 + h² - 5    ...(i)

⇒ 10 (h + 2) - 2h       ...(ii)

Substitute h = 9 in (i), we get;

⇒ 7 + h² - 5 = 7 + 9² - 5

                  = 7 + 81 - 5

                  = 83

And, Substitute h = 9 in (ii), we get;

⇒ 10 (h + 2) - 2h = 10 (9 + 2) - 2 x 9

                         = 10 x 11 - 18

                         = 110 - 18

                         = 92

Thus, We get;

⇒ 7 + h² - 5 < 10 (h + 2) - 2h

Therefore, The relation between the expression at h = 9 will be;

⇒ 7 + h² - 5 < 10 (h + 2) - 2h

Answer:

D. Yes, because it costs $12 per tin.

Step-by-step explanation:

The percentage of the students who are absent when 81 of the 1350 students are absent is 6%.

Percentage in simple words can be defined as a part per hundred.

In other words, it is the ratio which can be defined as a fraction of 100. It  is usually denoted by the symbol %.

Percentage can also be said as dimensionless number as it does not have any dimensions.

Percentage of a number can be calculated by dividing the number with the whole part and then multiplying by 100.

Total number of students in the school = 1350

Number of students absent = 81

Here we have to calculate the percentage of 81 out of 1350.

Percentage of the students who are absent = [tex]\frac{81}{1350}[/tex] × 100 = 6%

Hence 6% of the students are absent that day.

Hello my name is Galaxy and I will be helping you today! I hope you are having a nice day!

We can solve this in two steps, one being Algebra and the second being Answer/Checking our answer. I'll start off with Algebra.

Algebra

We can start to solve this problem by using Algebra and simplifying it down. We can also use the distributive property to solve the problem by using the proof it shows. The distributive property states that we can multiply whats inside the paranthesis by the number on the outside and get the same answer.

We can prove it by doing this:

[tex]2(1+4)=(2*1)+(2*4)?\\2+8=2+8?\\10=10[/tex]

Now that we have the tools we need to begin solving.

Solving

We can start to solve it by simplifying the equation from its distributive state. We can do that by doing the following:

[tex]-3(x-2)=12\\-3x+6=12\\[/tex]

Now that we've simplified, we can begin solving it.

[tex]-3x+6=12\\-3x=12-6\\-3x=6\\x=6 \div -3\\x=-2[/tex]

We have gotten our answer of x being -2. We can now double check our answers.

[tex]-3(-2-2)=12?\\(-3*-2)+(-3*-2)=12?\\6+6=12?\\12=12[/tex]

Remember that if we multiply two negatives it is a positive!

Cheers!

Using a system of equation, the amount in pounds of chocolate required is 4

Let :

Hence, we can create an equation thus :

0.45c + 6(1) = 0.78(6 + c)

0.45c + 6 = 4.68 + 0.78c

Collect like terms

6 - 4.68 = 0.78c - 0.45c

1.32 = 0.33c

Divide both sides by 0.33

c = 1.32 / 0.33

c = 4

Hence, 4 pounds of chocolate is required.

Answer:

It will take 25.2 minutes to complete 21 laps.

Step-by-step explanation:

The rate of covering 5 laps is:

v = 6/5

Therefore, the time taken to cover 21 laps is:

t = 21/v

t = 21*6/5

t = 25.2

Hence, it will take 25.2 minutes or 25 minutes 12 seconds for Lin to complete 21 laps.  

Answer:

D. The graphs are the same shape but have different y-intercepts.

Step-by-step explanation:

Step-by-step explanation:

there are 7 over 4 total possibilities to create a group of 3 or if 7.

that is

7! / (4! × (7-4)!) = 7×6×5 / 3×2 = 7×5 = 35

for the probability we need also the number of the desired cases, a the probability is

number of desired cases / number of total cases

the desired cases are all combinations, where G is a part of.

for that we make G a constant, and now we have only 6 variable candidates for the other 2 positions on the committee.

that is 6 over 2 or

6! / (2! × (6-2)!) = 6×5/2 = 3×5 = 15

so, the probability that G is in the committee is

15/35 = 3/7 = 0.428571429...
