Answer 1

[tex]\bf \sqrt{49}+(3+2)^2\implies \sqrt{49}+(5)^2\implies \sqrt{49}+25\implies 7+25\implies 32[/tex]

Answer 2

Answer: 43

Step-by-step explanation:

You have to use P.E.M. D.A.S. (Parentheses, Exponents, multiplication, division, addition, and subtraction.)

Starting with parentheses, 3+2= 6

Moving onto exponents, 6 squared is thirty six. Square roots, being the opposite of squares, are also done here. The square root of 49 is 7.

Now you add. 36 +7

The answer should be 43, unless I’m mistaken.

Solve a = 2x + 6xz for x

Answers

To solve the equation a = 2x + 6xz for x, isolate x on one side of the equation by following the steps: subtract 6xz from both sides, factor out x, and divide both sides by (2 + 6z).

To solve the equation a = 2x + 6xz for x, we need to isolate x on one side of the equation. Here are the steps:

Start with the equation: a = 2x + 6xz

Subtract 6xz from both sides: a - 6xz = 2x

Factor out x on the right side: a - 6xz = x(2 + 6z)

Divide both sides by (2 + 6z): (a - 6xz) / (2 + 6z) = x

Therefore, the solution for x is x = (a - 6xz) / (2 + 6z).

C.jeremy sister,Susie ,borrowed the money from their mom to pay for her order. The mother has agreed to deduct an equal amount of money from suzie allowance each week for the next five weeks to repay the loan . What is the weekly change in suzie allowance?

Numerical answer:

Explanation:


D. Jeremy grandparents want to change their order. They want to order three daisies and one geranium, instead of your daisies. How does this change affect the amount of their order? Explain how you arrived at your answer.


E. Jeremy approaches three people who do not want to buy any plants; however,they wish to donate some money for the fundraiser when Jeremy delivers the plants one week later. If the people promise to donate a total of $14.40, what will be the average cash donation?


F. Jeremy spends one week collecting orders.If 22 people purchase plants totaling $270,what is the average amount of Jeremy sale?

Numerical answer:

Explanation:

Answers

A) The total for the plants she buys is 8.50, so the change in her checking account would be -8.50, because they will take 8.50 out of her account when the check is cashed, the amount in her account is lowered.

B) Mr. Clark's total is 11.25. If he pays with a 20, subtract the plant total from 20:

20 - 11.25 = 8.75 is the amount of change Jeremy owes him.

The amount of money Jeremy collects would be that amount higher than what he needs.

C)  Suzie owed 2.50, divide the amount she borrowed by the number of weeks her mom is keeping money:

2.50 / 5 = 0.50

Her allowance will be 0.50 less than what she normally would get.

D) Grandparents original amount = $15.00

3 daises = 3 x 3.75 = 11.25

1 geranium = 2.25

Total for new order = 11.25 + 2.25 = 13.50

Difference = 15 - 13.50 = 1.50

The new order would be $1.50 less.

E) Divide the total amount of the donation by the number of people:

14.40 / 3 = $4.80

F) Divide total amount by total people:

270 / 22 = $12.27 average

How many user must mike recruit in order for him to steam movies for free? The service costs $43.75 a month, but mikes rate is reduced by $1.25 for each new subscriber that he gets to sign up.

Answers

Answer:

35 subscribers

Step-by-step explanation:

Divide $43.75 by $1.25.

$43.75/$1.25 = 35

For each subscriber he gets, his service goes down by $1.25.

Since 35 * $1.25 = $43.75, for 35 new subscribers, his service will go down by $43.75.

He pays $43.75, so if the service goes down by $43.75, he will pay nothing since $43.75 - $43.75 = 0.

Answer: 35 subscribers

Follow below steps:

To determine how many users Mike must recruit for him to stream movies for free, we need to set up a simple algebraic equation. Mike's service costs $43.75 per month, and for each new subscriber he recruits, his rate is reduced by $1.25. Let's say the number of users Mike needs to recruit is represented by x.

The cost reduction for recruiting x users would be $1.25x. To get a free service, the total cost reduction must equal the monthly service cost of $43.75. Thus, the equation is $1.25x = $43.75.

To solve for x, we divide both sides by $1.25:

x = $43.75 / $1.25

x = 35

Therefore, Mike must recruit 35 new subscribers to stream movies for free.

Answers

Answer: Last option.

Step-by-step explanation:

In order to estimate the percent "n" of a number"x", you need easy numbers to work with, therefore you can round  "n" and "x" up or down; but it is important to remember that this estimation does not give you an exact value.

You can observe that Sergei's first step was to round 149% and 67 up, getting this result:

Which ordered pair is a solution of the equation? -3x-y=6

Answers

There are an infinite number of solutions, but some that work are (-2,0), (1,-3), and (0,-6)

The correct answer is (B) Only (-3, 3).

To determine which ordered pair is a solution of the equation, you need to substitute the values of \( x \) and \( y \) into the equation and see if it holds true. Let's check:

For option A: (-4, 4)
Substituting into the equation: \( -3(-4) - 4 - 6 = 12 - 4 - 6 = 2 \) which is not equal to 0, so it's not a solution.

For option B: (-3, 3)
Substituting into the equation: \( -3(-3) - 3 - 6 = 9 - 3 - 6 = 0 \) which is equal to 0, so it is a solution.

Thus, the correct answer is (B) Only (-3, 3).

Which scale would produce the largest scale drawing of an object when compared to the actual object?

A. 1 inch : 5 feet

B. 1 inch : 30 inches

C. 1 foot : 12 yards

D. 1 centimeter : 1 meter

Answers

Covert the ratios so they are all the same measurement type.

A. 5 feet = 5 x 12 = 60 inches.

The scale becomes 1:60

B. 1:30

C. 12 yards = 12 x 3 = 36 feet x 12 = 432 inches.

The scale is 12:432  = 1:36

D. 1 meter = 39.37 inches.

1 inch = 2.54 cm

39.37 x 2.54 = 99.99 inches

The scale converted to inches becomes 1 :100 inches.

The first number would be the size of the drawing, the second number is the size of the actual object

If you use all 4 scale factors for a real object that is 100 inches:

A would need 100/60 = 1.67 inches.

B would need 100/30 = 3.3 inches.

C would need 100/36 = 2.78 inches.

D would need 100/100 = 1 inch.

The larger scaled drawing would be B.

Answer:

Option B.

Step-by-step explanation:

We need to find which scale would produce the largest scale drawing of an object when compared to the actual object.

First of all cover all units in inches.

In option 1,

1 inch : 5 feet

We know that

1 feet = 12 inch → 5 feet = 60 inch

So the ratio in inches is 1:60. It means the scale factor is 60.

In option 2,

1 inch : 30 inches

So the ratio in inches is 1:30. It means the scale factor is 30.

In option 3,

1 foot : 12 yards

12 inches : 12 yards                     (1 feet = 12 inch)

1 inch : 1 yards

1 inch : 36 inch                     (1 yard = 36 inch)

So the ratio in inches is 1:36. It means the scale factor is 36.

In option 4,

1 centimeter : 1 meter

1 centimeter : 100 centimeter         (1 m = 100 cm)

1 inch : 100 inch

So the ratio in inches is 1:100. It means the scale factor is 100.

Option B has smallest scale factor, so it will produce the largest scale drawing of an object when compared to the actual object.

Therefore, the correct option is B.

Solve the inequality

Answers

Answer:

x < 3

Step-by-step explanation:

Apply distributive property on the left of the inequality to get rid of the parenthesis:

8+4x > 5x+5

subtract 4x from both sides to group all terms with x on the right:

8 > 5x-4x+5

8 > x +5

Now subtract 5 from both sides to collect all numerical terms on the left:

8 - 5 > x

3 > x

Therefore the solution to the inequality are of those real numbers strictly smaller than 3.

The inequality can be written as x < 3 or also as we had it initially: 3 > x

Notice that the opening of the angle symbol is always facing the number 3 , meaning that 3 is the larger of the two numerical objects that are compared.

Have a nice day!!!!!! :-)

KA

Final answer:

To divide 64.8 by 7 using long division, calculate how many times 7 can be subtracted from each part of the number 64.8 in sequence. This results in the final answer of 9.25.

Explanation:

To find 64.8 divided by 7 using long division, first write down 64.8 with a division bar over it and 7 on the left side of the bar. You would write:

7 | 64.8

Next, ask: How many times does 7 go into 64? This is 9 times since 7 times 9 is 63. Record the 9 above the line and record the product (63) below 64. Subtract 63 from 64 to get 1.

Bring down the 8 (from 64.8) to the right of the 1. Now you have 18. Ask how many times does 7 go into 18? This is 2 times. So you add the digit 2 next to 9 on top of the bar. 7 times 2 is 14.

Subtract 14 from 18 to get 4. As the decimal point should be straight up from where it is in the 64.8, record a decimal point.

Now, since there's no more numbers to bring down, you can add a 0 to 40. 7 goes into 40, 5 times. Therefore, we add 5 next to the 2 after the decimal point. So, 64.8 divided by 7 is 9.25.

What is Equation Modelling?

Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

We have Cask’n’Cork wine shop that has a markup rate of 15%. A bottle of zinfandel wine costs $12.48 wholesale.

Assume that the shop charges $x. Then, we can write -

x = 12.48 + 15% of 12.48

x = 12.48 + (15/100) x 12.48

x = 12.48 + (3/20) x 12.48

x = 12.48 + 1.872

x = 14.352

Therefore, the shop will charge $14.352 as markup price.

If a line passes through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex], then the slope of the line is

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Consider any two points of the line: (0, 0) and (1, 3). So, the slope of the given line is

[tex]m=\frac{3-0}{1-0}[/tex]

[tex]m=3[/tex]

Therefore, the slope of the line is 3.
