Answer:

13.6 i believe, but that could, should be right tho.

Step-by-step explanation:

355/17=20.88235294 then 284/20.88235294=13.6

For this case, you want to know how many gallons of gasoline Nicole needs to drive 284 miles, knowing that with 17 she drove 355 miles. For this, we make a rule of three:

[tex]355 \ miles -----------> 17 \ gallons\\284 \ miles -----------> x[/tex]

Where "x" represents the number of gallons consumed in 284 miles.

[tex]x = \frac {284 * 17} {355}\\x = 13.6 \ gallons[/tex]

So, Nicole will need 13.6 gallons of gas to drive 284 miles

Answer:

13.6 gallons

Answer:Part A 1.1 and Part B .75

Step-by-step explanation:

2.2 divided by 2 is 1.1

3.75 divided by 5 is .75

Answer:

Part A: 1.1 Part B: 0.75

Step-by-step explanation: For part A it's 1.1 because there's 2. stamps there and 1.1 + 1.1 = 2.2. For part A it's 0.75 because 3.75 divided by 5 is 0.75

The angle of elevation of the ramp (x) is approximately 58.9 degrees.

How to find the angle of elevation

To find the angle of elevation (x) of the ramp using the cosine function,

cos(x) = adjacent / hypotenuse

Given:

Adjacent side = 16 ft

Hypotenuse = 31 ft

Plug in these values into the formula

cos(x) = 16 / 31

To find x, take the inverse cosine (arccos) of both sides:

x = arccos(16 / 31)

Using a calculator,  arccos(16 / 31) is approximately 58.9 degrees.

Therefore, rounding to the nearest tenth of a degree, the angle of elevation of the ramp (x) is approximately 58.9 degrees.

Answer:

The period is [tex]2\pi[/tex] and the amplitude is 3.

Step-by-step explanation:

The period goes from one peak to the next (or from any point to the next matching point). The amplitude is the height from the center line to the peak.

The period of the function [tex]y=a\sin (bx)[/tex] is [tex]T=\dfrac{2\pi }{b}[/tex] and the amplitude is [tex]|a|.[/tex]

Consider the function [tex]f(t)=-3\sin t.[/tex]

The period for the function [tex]f(t)[/tex] is

[tex]T=\dfrac{2\pi}{1}=2\pi[/tex]

and the amplitude is 3.

Answer:

π4;3π4

Step-by-step explanation: Trig table gives:

sinx=√22 --> arc x=π4

Unit circle gives another arc x that has the same sin value:

x=π−π4=3π4

The exact value of [tex]\(\arcsin(-2\sqrt{2})\)[/tex] is not defined within the real numbers because the sine function has a range of [tex]\([-1, 1]\)[/tex], and the argument [tex]\(-2\sqrt{2}\)[/tex] lies outside this interval. The arcsine function, [tex]\(\arcsin(x)\)[/tex], is only defined for [tex]\(x\)[/tex] in the interval [tex]\([-1, 1]\)[/tex] .

To illustrate, the sine function reaches its maximum value of [tex]\(1\)[/tex] at [tex]\(\frac{\pi}{2}\)[/tex] and its minimum value of [tex]\(-1\)[/tex] at [tex]\(-\frac{\pi}{2}\)[/tex]. Any value outside the interval [tex]\([-1, 1]\)[/tex] is not within the domain of the inverse sine function. Therefore,[tex]\(\arcsin(-2\sqrt{2})\) does not have a real value.[/tex]

However, if we were to consider complex numbers, we could use Euler's formula and the definition of the complex logarithm to find a complex value for [tex]\(\arcsin(-2\sqrt{2})\)[/tex]. The general formula for the arcsine of a complex number [tex]\(z\)[/tex] is given by:

[tex]\[ \arcsin(z) = -i \ln\left(iz + \sqrt{1 - z^2}\right) \][/tex]

For [tex]\(z = -2\sqrt{2}\)[/tex], we would have:

[tex]\[ \arcsin(-2\sqrt{2}) = -i \ln\left(-2i\sqrt{2} + \sqrt{1 - (-2\sqrt{2})^2}\right) \][/tex]

Simplifying the expression under the square root:

[tex]\[ \sqrt{1 - (-2\sqrt{2})^2} = \sqrt{1 - 8} = \sqrt{-7} \][/tex]

Since [tex]\(\sqrt{-7} = i\sqrt{7}\)[/tex], we can continue the calculation:

[tex]\[ \arcsin(-2\sqrt{2}) = -i \ln\left(-2i\sqrt{2} + i\sqrt{7}\right) \][/tex]

This expression involves the complex logarithm, which is multi-valued due to the periodicity of the complex exponential function. Therefore, the value of [tex]\(\arcsin(-2\sqrt{2})\)[/tex] in the complex plane is not unique and requires careful handling of the branch cuts of the logarithm function. However, as stated earlier, within the realm of real numbers, [tex]\(\arcsin(-2\sqrt{2})\)[/tex] is undefined.

Answer:

Answer: g(x) = 32x - 7

Step-by-step explanation:

A vertical stretch is accomplished by multiplying by a constant greater than 1

So f(x) would be multiplied by 4 to get part of g(x)

4*f(x) = 4*8x = 32x

Now to get 7 units down subtract 7 from f(x)

4f(x) - 7= 32x - 7 Down is minus.

Answer: g(x) = 32x - 7

Answer:

The new price of the coat is $201.25

Step-by-step explanation:

The price will be higher since this is an increase.

Percent increase = (new price - old price) / old price

Substituting what we know

.15 = (new price -175)/175

Multiplying each side by 175

.15*175 = new price by 175

26.25 = New price-175

Add 175 to each side

26.25+175 = new price-175+175

201.25 = new price

The new price of the coat is 201.25

Final answer:

The new price of the winter coat after a 15% price increase on the original price of $175 is $201.25.

Explanation:

To find the increase, we need to calculate 15% of $175:

Increase = 15% of $175

= 0.15 * $175

= $26.25

Calculate the New Price:

To find the new price, we add the increase to last year's price:

New Price = Last Year's Price + Increase

= $175 + $26.25

= $201.25

Therefore, the new price of the winter coat after a 15% increase is $201.25.

"The graphs of [tex]\( y = x^2 \)[/tex] and [tex]\( y = 25 \)[/tex] intersect at the points where the value of [tex]\( x^2 \)[/tex] is equal to 25. To find these points, we set the equations equal to each other and solve for x :

[tex]\[ x^2 = 25 \][/tex]

Taking the square root of both sides gives us two solutions:

[tex]\[ x = \pm 5 \][/tex]

Therefore, the graphs intersect at [tex]\( (-5, 25) \) and \( (5, 25) \)[/tex].

Similarly, the graphs of [tex]\( y = x^2 \)[/tex] and [tex]\( y = 121 \)[/tex] intersect at the points where the value of [tex]\( x^2 \)[/tex] is equal to 121. We set the equations equal to each other and solve for [tex]\( x \)[/tex]:

[tex]\[ x^2 = 121 \][/tex]

Taking the square root of both sides gives us two solutions:

[tex]\[ x = \pm 11 \][/tex]

Thus, the graphs intersect at[tex]\( (-11, 121) \) and \( (11, 121) \)[/tex].

In both cases, the intersection points are determined by finding the values of [tex]\( x \)[/tex] that satisfy the equation [tex]\( x^2 = k \)[/tex], where[tex]\( k \)[/tex]is the constant on the right side of the equation[tex]\( y = k \)[/tex].

The solutions are the positive and negative square roots of [tex]\( k \)[/tex], since [tex]\( x^2 \)[/tex] is equal to [tex]\( k \)[/tex] at these points."

Given that A statistics teacher conducted an experiment to test whether the use of a new review booklet will improve her students' semester grades.

also given that The teacher randomly selected 20 students from her class and assigned the new review booklet to 10 of the students. The remaining 10 students did not use any review material.

The semester grades did not differ for both groups.

But we cannot conclude the booklet has no effect because,

i) The sample size is very small, only 10.  Hence not reliable

ii) We do not know the previous performance of both the groups. To ensure improvement the grades the students got in the previous exam also should be considered.

x = -2

Step-by-step explanation:

If you factor out 1/9 you get rid of the fractions and that makes the equation a whole lot easier.

[tex](5x+10)^2 - x(25x+27) + 46 = 0[/tex]

Next, eliminate the brackets:

[tex]25x^2 +100x + 100 - 25x^2 - 27x + 46 = 0[/tex]

Combine the terms:

[tex]x = \frac{- 146}{73} = -2[/tex]

Answer:

x = - 2

Step-by-step explanation:

The 9 does absolutely nothing. Multiply the whole equation by. 9. Remember that each term must show the 9 is missing

(5x + 10)^2 - x(25x + 27)  + 46 = 0

Next expand the first and second binomial so that the brackets can be removed.

(25x^2 + 100x + 100) - (25x^2 + 27x) + 46 = 0  

Now remove the brackets

25x^2 + 100x + 100 - 25x^2 - 27x + 46 = 0

Collect the like terms

25x^2 - 25x^2 + 100x - 27x + 100 +46 = 0

73x + 146 = 0                

Subtract 146 from both sides

73x = - 146

Step-by-step explanation:

The segment that is x units long is the midsegment of the largest triangle. The midsegment is half as long as the line parallel to the midsegment. It is half as long as the 30 unit long segment.

Note how the vertical sides (marked with the double tickmarks) are congruent to one another. The smaller pieces are both the same length, so they combine to something twice as big. Go in reverse: one segment with a pair of double tickmarks is exactly half as long as the entire vertical side. The same can be said about the horizontal sides as well.

Answer:

2 3/6

Step-by-step explanation:

You must turn 1 2/3 and 1 1/2 into improper fractions. You then multiply them and get an answer of 15/6, but since 6 can go into 15 twice (6x2=12+3=15), you get a whole of 2 and 3/6.

Final answer:

Marie will need to cover an area of 2 1/2 square feet with fertilizer for her planter that is 1 1/2 feet long and 1 2/3 feet wide.

Explanation:

The question asks to calculate the area that needs to be covered with fertilizer for a planter with given dimensions.

Step-by-Step Solution:

Convert the dimensions of the planter into improper fractions for easier multiplication. The length is already given as an improper fraction (1 1/2 feet which is 3/2 feet). The width is 1 2/3 feet, which is 5/3 feet when converted.

Multiply the length by the width to find the area in square feet: (3/2) × (5/3) = 15/6 square feet.

Simplify the calculated area if necessary. The area 15/6 can be simplified to 2 1/2 square feet.

Therefore, Marie will need to spread fertilizer over an area of 2 1/2 square feet.

Answer:

B & D

Step-by-step explanation:

We use percents in decimal form to multiply it with the price. We convert percents into decimals by dividing the percent number by 100. For example, 78% divided by 100 becomes 0.78.

There are two ways to look at it:

For finding the price we pay during a sale, we focus on the percent we pay. If 22% off is the sale, then we spend 78% or 100-22=78. If 20% off is the sale, then we pay 80% or 0.80. Multiply that by x an unknown price and we have 0.8x.

We can find the percent off by multiplying the price by the percent conversion. So 20% is 0.20. Then subtract it from the original price to find the leftover that we pay. This is x-0.2x.

Answer:

B and D

Step-by-step explanation:

Answer:

D, which is 7.

Step-by-step explanation:

if you notice that -2+4= 2, and 4+14= 18, you can make an educated guess.

The missing number in the given synthetic division problem is 7 hence, option (D) is correct.

The synthetic division used to divide a polynomial by any expression in that expression should be the leading coefficient as one.

Given that in problem first term has written as it is.

Then multiply 2 with 2 and add 4 with -2.

Again multiply 2 by 2 and add with 3 which gives 7.

Hence 7 will be the missing number in the given problem.

(b)

Graph is attached

(c)

Sam earned =$200

Kevin earned =$225

Step-by-step explanation:

Let's assume

's' for the amount Sam earned

'k' for the amount Kevin earned

(a)

Together they earned a total of $425

so, we get

[tex]s+k=425[/tex]

Kevin earned $25 more than Sam

so, we get

[tex]k=s+25[/tex]

so, system of equations are

[tex]s+k=425[/tex]

[tex]k-s=25[/tex]

(b)

now, we can draw graph

(c)

intersection point will be our solution

and we got intersection point as

(200, 225)

so,

s=200

k=225

(a) The system of equations for the situation is s + k = 425 and k = s + 25.

(b) Graph these equations to find their point of intersection.

(c) Using the graph, estimate that Sam earned around $200, and Kevin earned around $225.

(a) To write a system of equations for this situation, we can use the information provided:

1. Sam and Kevin earned a total of $425, which can be expressed as:

  s + k = 425

2. Kevin earned $25 more than Sam:

  k = s + 25

So, the system of equations is:

1. s + k = 425

2. k = s + 25

(b) To graph these equations, you can rearrange them into slope-intercept form (y = mx + b), where y represents one of the variables (s or k) and x represents the other variable.

From equation 2, we can rewrite it as k = s + 25, which can be expressed as k = 1s + 25.

Now, the system is represented as:

1. s + k = 425

2. k = s + 25

You can graph these equations on a coordinate plane.

(c) Once you graph the equations, you can look for the point of intersection, which represents the solution to the system and gives you the values of s and k. The point where the two lines intersect will provide estimates for how much Sam and Kevin earned. Using the graph, estimate that Sam earned around $200, and Kevin earned around $225.

When subtracting mixed numbers, rename the mixed number if the subtrahend is larger than the minuend by converting them into improper fractions and then subtracting the numerator while keeping the denominator the same.

When subtracting mixed numbers, you may need to rename the mixed number if the subtrahend is larger than the minuend.

This means that the whole number part of the subtrahend is greater than the whole number part of the minuend, or the fractions have different denominators.

To rename the mixed number, you convert it into an improper fraction.

Once both mixed numbers are in the same form, you can subtract them by subtracting the numerator and keeping the denominator the same. Finally, simplify the answer if needed.

Final answer:

With Helen fixed in the first position, there are 6 different ways Elizabeth, Frank, and Gary can line up behind her, computed by a permutation of the 3 remaining people.

Explanation:

If Helen is always the first in line, we just need to focus on the different ways Elizabeth, Frank, and Gary can line up behind her. For the first spot behind Helen, there are 3 choices (Elizabeth, Frank, or Gary). After choosing one, there are 2 remaining choices for the next spot, and finally, the last person will have no choice but to take the last remaining spot. This is a permutation problem where we multiply the different choices together.

Thus, the number of ways they can line up is 3 (for the second spot)  imes 2 (for the third spot)  imes 1 (for the last spot), which equals 6 different possible lineups.
