Answer:

the difference between the two fractions is 1/10

Step-by-step explanation:

when solving this problem you must switch the denominators to the same number. in this case thats 30. so 10*3 is 30 and 15*2 is 30. so then we multiply 7*3 to get 21 and 14*2 to get 24. so now we have 21/30 and 24/30, so then we compare. and we end up with 3/30, we simplify the answer to 1/10.

The solution to the equation is n = -2.

To solve the equation 30 = -5(6n + 6) step-by-step, follow these procedures:

Step 1: Distribute the -5 on the right side:

30 = -5 * 6n - 5 * 6

Step 2: Simplify the right side:

30 = -30n - 30

Step 3: Move constant term to one side:

30 + 30 = -30n

Step 4: Combine like terms:

60 = -30n

Step 5: Divide both sides by -30 to isolate 'n':

n = 60 / -30

Step 6: Simplify the right side:

n = -2

The solution to the equation is n = -2.

Answer:

C, 38°

Step-by-step explanation:

ray UW is the angle bisector of ∠VUT

--> m∠VUW = m∠WUT = 1/2 m∠VUT

<=> 4x + 6 = 6x - 10

<=> 6 + 10 = 6x - 4x

<=> 2x = 16

<=> x = 8

So, the measure of m∠WUT is: 6x - 10 = 6 . 8 - 10 = 48 - 10 = 38°

Answer:

Ok, we have:

d(t) = 3*t^2 + 5*t - 2.

The first interval is:

(2, 3)

and remember that, for an interval (a,b), the difference quotient is:

D = (f(b) - f(a))/(b -a)

Then in this first interval we have:

[tex]d = \frac{d(3) - d(2)}{3-2} = \frac{3*3^2 + 5*3 - 2 - (3*2^2 + 5*2 - 2)}{1} = 20[/tex]

So the average rate of change in (2,3) is 20.

now, in (2, 2.5) we have:

[tex]d = \frac{d(2.5) - d(2)}{3-2} = \frac{3*2.5^2 + 5*2.5 - 2 - (3*2^2 + 5*2 - 2)}{1} = 9.25[/tex]

So here the rate of change is 9.25

And in the interval (2, 2.1) we have:

[tex]d = \frac{d(2.1) - d(2)}{3-2} = \frac{3*2.1^2 + 5*2.1 - 2 - (3*2^2 + 5*2 - 2)}{1} = 1.73[/tex]

So in this interval the rate of change is 1.73

Answer:

2 to 3 is 20

2 to 2.5 is 15

Answer:

x=2

Step-by-step explanation:

-3x+12=-18

-3x=-18+12

-3x=-6

x=-6/-3

x=2

Answer:

x=10

Step-by-step explanation:

We are given the equation:

[tex]-3x+12= -18[/tex]

and asked to solve for x. Therefore, we must isolate x on one side of the equation.

12 is being added to -3x. The inverse of addition is subtraction. Subtract 12 from both sides of the equation.

[tex]-3x+12-12= -18 -12[/tex]

[tex]-3x= -18-12[/tex]

[tex]-3x=-30[/tex]

x is being multiplied by -3. The inverse of multiplication is division. Divide both sides of the equation by -3.

[tex]-3x/3=-30/-3[/tex]

[tex]x= -30/-3[/tex]

[tex]x=10[/tex]

Let's check our solution. Plug 10 in for x and solve.

[tex]-3x+12=-18[/tex]

[tex]-3(10)+12=-18[/tex]

Multiply -3 and 10.

[tex]-30+12=-18[/tex]

Add 12 to -30.

[tex]-18=-18[/tex]

This checks out, so we know our solution is correct.

The solution -3x+12=-18 is x=10.

(- 1, 4 ) is a solution to the equation

Step-by-step explanation:

Substitute x = - 1 and y = 4 into the left side of the equation and if the value obtained is equal to the right side then it is a solution

Given

3x + 8y = 29, then

3(- 1) + 8(4) = - 3 + 32 = 29 = right side

Answer:

Restaurant Server: 10%

Florist: 10%

Cab Care: 0%

Dog Groomer: 5%

Step-by-step explanation

Also, in the question it says round to make a more resonable number for example in the chart for the resturant it says the cost is $40 dollars and the gratuity is 18% and the tax is 8.5% with this you round 18% to 20% and the tax 8.5% to 9% and round that to 10% and when you round the  tax to 10% that is your anwser. Then with all the other numbers on the chart do the same thing and there is all of your anwsers.

Restaurant Server: 8%

Florist: 12%

Cab Fare: 0%

Dog Groomer: 6%

Restaurant Server:

The cost is $40 and the gratuity is 18%.

To calculate the tax, you multiply the cost by the tax rate, which is 8.5% (or 0.085).

The tax amount would be $40 × 0.085 = $3.40. Rounding this to the nearest whole number would be $3.

Therefore, the tax estimate for the restaurant service would be 8%.

Florist:

The cost is $94 and the gratuity is 12%.

The tax rate for the florist service is 12% (or 0.12).

Calculating the tax amount would be $94 × 0.12 = $11.28. Rounding this to the nearest whole number would be $11.

Hence, the tax estimate for the florist service would be 12%.

Cab Fare:

The cost is $32, and the gratuity is 20%.

The tax for cab fares is mentioned as 0%, which means there is no tax applicable. In this case, rounding is not necessary as the tax amount is already 0%.

Dog Groomer:

The cost is $62, and the gratuity is 26%. The tax rate for the dog groomer service is 5.75% (or 0.0575).

Calculating the tax amount would be $62 × 0.0575 = $3.57.

Rounding this to the nearest whole number would be $4.

Thus, the tax estimate for the dog groomer service would be 6%.

Answer: 90

Step-by-step explanation:

We first need to find three consecutive numbers that adds up to 267. We know that the numbers will be somewhat close to 100 because the sum needs to be past 250.

Let's try 85,86,87.

85+86+87=258

258 is very close to 267. We know that we need to increase our numbers.

Let's try 88,89,90.

88+89+90=267

88,89, and 90 added together gives us 267. The question asks for the largest integer. In 88, 89, 90, 90 is the largest integer.

-3(6 - 2x) > 4x + 12

-18 + 6x > 4x + 12

2x > 30

x > 15

The solution set is (15, ∞).

The interval that includes all possible values of x that satisfy the inequality is (15, infinity), which can be written as [15, oo) in interval notation.

The answer is (d) [15,00)

The intervals are numbers or values between two given point

The intervals are denoted as:

Closed intervals = [a, b]

This interval includes a and b.

Open intervals = (a, b)

This interval does not include a and b.

We have,

We can solve the inequality as follows:

-3(6 - 2x) > 4x + 12

Distribute the -3 on the left side:

-18 + 6x > 4x + 12

Subtract 4x from both sides:

2x > 30

Divide both sides by 2:

x > 15

Therefore,

The interval that includes all possible values of x that satisfy the inequality is (15, infinity), which can be written as [15, oo) in interval notation.

Answer:

0.02275

Step-by-step explanation:

We use this z score formula to solve for this question

z-score is is z = (x-μ)/σ/√n

where x is the raw score

μ is the population mean

σ is the population standard deviation

From the above question,

x = 77

μ = 75

σ = 7

number of samples = 49

Hence, the z score = 77 - 75/ (7/√49)

= 2/(7/7)

= 2/1

= 2

Hence, the z score = 2

Using the z table to find probability

P(x<77) = 0.97725

P(x>77) = 1 - P(x<77)

= 1 - 0.97725

= 0.02275

Therefore, the probability that the same mean will be larger than 77 years

is 0.02275
