Answer:

[tex]2x\sqrt{40x}-2x\sqrt{5}[/tex]

Step-by-step explanation:

[tex]2x\sqrt{40x}-2x\sqrt{5}[/tex] is found by first, siplifying the radicals in the parenthesis. [tex]\sqrt{8x^{2} }[/tex] can be simplified as [tex]2x\sqrt{2}[/tex] and [tex]-2\sqrt{x}[/tex] stays the same. Now we have to multiply these two by [tex]\sqrt{5x}[/tex] which then results in [tex]2x\sqrt{40x}-2x\sqrt{5}[/tex]

Answer:

x = 1 or x = -3/2

Step-by-step explanation:

Solve for x over the real numbers:

2 x^2 + x - 3 = 0

The left hand side factors into a product with two terms:

(x - 1) (2 x + 3) = 0

Split into two equations:

x - 1 = 0 or 2 x + 3 = 0

Add 1 to both sides:

x = 1 or 2 x + 3 = 0

Subtract 3 from both sides:

x = 1 or 2 x = -3

Divide both sides by 2:

Answer: x = 1 or x = -3/2

Answer:

The correctly rotated red triangles are those of (1), (2), and (5)

Step-by-step explanation:

In a 90° counterclockwise rotation, every x and y points of the original triangle are switched while the y is turned negative, as shown in the following equation;

(x, y) to (-y, x)

Therefore, the triangles that undergo a 90° counterclockwise rotation are as follows;

1) Blue triangle points; (-1, 4), (-5, 4), and (-1, 1)

Red triangle points; (-4, -1), (-1, -1). and (-4, -5)

(-1, 4) → (-4, -1)

Answer: 51.54 ft

Step-by-step explanation:

The ladder should be 1 feet away from the wall by each 4-feet that the wall rises, so if we have a 50 ft wall, the distance between the bottom of the ladder and the wall must be:

50ft/4 = 12.5ft.

Now we know the cathetus of our ladder, 12.5ft and 50ft, let's find the hypotenuse, that is:

H = √(12.5^2 + 50^2) = 51.54 feet.

Which is also the lenght of our ladder, so the shortest ladder to climb safely a 50 ft wall is 51.54 ft long.

Answer:

A line that passes (2, 0) and (-6, 3) has slope:

S1 = (-6 -2)/(3 - 0) = -4/3

Another line that is perpendicular with above line has slope:

S2 = -1/S1 = -1/(-4/3) = 3/4

=> Option B is correct

Hope this helps

:)

The segment with endpoints (2,0) and (-6,3) has a line perpendicular to it with a slope of 4/3.

A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. Sometimes, the aforementioned is referred to as a "linear equation of two variables," with y and x serving as the variables.

From the general formula of the slope:

slope = (change in y) / (change in x)

The change in y is 3 - 0 = 3, and the change in x is -6 - 2 = -8. So the slope of the segment is:

slope = (3 - 0) / (-6 - 2) = -3/4

To find the slope of the line perpendicular to the segment, we know that it must have the opposite reciprocal slope. That is:

the slope of perpendicular line = -1 / slope of segment

slope of perpendicular line = -1 / (-3/4) = 4/3

Therefore, the slope of the line perpendicular to the segment with endpoints (2,0) and (-6,3) is 4/3.

Answer:

58º

Step-by-step explanation:

Answer:

58 degrees

Step-by-step explanation:

x and 32 are complementary, which means they must add to 90 degrees.

x+32=90

Now, we have to solve for x. To do this, we need to get x by itself. 32 is being added on to x. To reverse this, subtract 32 from both sides, because subtraction is the opposite of division.

x+32-32=90-32

x=90-32

x=58

x is 58 degrees

To find the total amount of fabric Diana used, we must sum those fractions

[tex]\frac{3}{8} +\frac{2}{8}=\frac{5}{8}[/tex]

Diana uses 5/8 square yard of fabric for both pillows.

Now, we subtract to find the remaining amount of fabric

[tex]1-\frac{5}{8}=\frac{8-5}{8}=\frac{3}{8}[/tex]

Therefore, there remains 3/8 square yard of fabric.

Answer:

8 cm and 10 cm

Step-by-step explanation:

Hello, I can help you with this.

Step 1

According to the question there are two rectangles A and B,

Rectangle A is a scale drawing of Rectangle B and has 25% of its area

in other words

[tex]Area_{A}=0.25*Area_{B} (Equation\ 1)\\[/tex]

Step 2

Let

Rectangle A

length (1)= 4 cm

length (2)= 5 cm

[tex]Area_{A}=4\ cm * 5\ cm\\Area_{A}=20\ cm^{2}[/tex]

put this value into equation 1

[tex]Area_{A}=0.25*Area_{B} (Equation\ 1)\\\\20\ cm^{2} =0.25*Area_{B} \\divide\ each\ side\ by\ 0.25\\\frac{20\ cm^{2} }{0.25}=\frac{0.25}{0.25}*Area_{B}\\ Area_{B}=80\ cm^{2}[/tex]

Now, we know the area of rectangle B, to know its length we need to formule other equation

Step 3

[tex]Area_{B}=80\ cm^{2}\\length (1B)*length (2B)=80\ cm^{2} (equation\ 2)\\[/tex]

the ratio between the lengths must be constant, so the ratio of A must be equal to ratio in B, then

[tex]\frac{length(1A)}{length(2A)}=\frac{length(1B)}{length(2B)} \\\\\\frac{4}{5}= \frac{length(1B)}{length(2B)}\\0.8=\frac{length(1B)}{length(2B)}\\length(1B)=0.8*length(2B) (Equation 3)[/tex]

Step three

using Eq 1 and Eq 2 find the lengths

put the value of length(1B) into equation (2)

[tex]length (1B)*length (2B)=80\ cm^{2} (equation\ 2)\\\(0.8*length(2B)) (*length (2B)=80\ cm^{2} \\\\0.8*(length (2B))^{2} =80\ cm^{2}\\(length (2B))^{2} =\frac{80\ cm^{2}}{0.8} \\(length (2B))^{2}=100\\\sqrt{(length (2B))^{2}}=\sqrt{100\ cm^{2}} \\ length (2B)=10\ cm[/tex]

Now, put the value of length(2B) into equation 3 to know length (1B)

[tex]length(1B)=0.8*length(2B)\\length(1B)=0.8*10\ cm\\length(1B)=8 cm[/tex]

Answer: that the variable can be any number.

Step-by-step explanation:

So we have a linear equation and we end with a relation of the way:

x = x

an example can be if we have:

2*x + 4 = 2*(x + 2)

if you solve that, you will end with a relationship x = x

this means that any value of x will made that equality true.

so x can be any number.

Step-by-step explanation:

Answer:

1) The windsurfer is approximately 580 ft from each lifeguard stand.

2) The distance between the Earth and Mercury is approximately 61 million miles.

Step-by-step explanation:

The image other two situations described is presented in the attached image to this answer.

1) From the attached image, the windsurfer forms a right angled triangle with each of the lifeguard stand and the midpoint between the two lifeguard stands.

Hence, the angle at the top of the triangle is half of 30°, 15° and the distance from the midpoint of the lifeguard stands to the lifeguard stands is 300/2 = 150 ft.

Let the required distance of the windsurfer from each of the lifeguard stands be x.

Using trigonometric relations,

Sin 15° = (150/x)

x = 150 ÷ sin 15° = 150 ÷ 0.2588

x = 579.6 ft = 580 ft to the nearest whole number

2) From the image, the Sun, Earth and Mercury form a triangle.

Let the possible distance between the Earth and Mercury be y.

Using cosine rule,

y² = 36² + 93² - (2×36×93×cos 22°)

y² = 3,736.5769098208

y = √3,736.5769098208 = 61.13 million miles = 61 million miles to the nearest million miles.

Answer:

100:59

Step-by-step explanation:

For every pound a company spends on advertising, it spends £0.59 on its website.

Amount Spent on Advertising = £1

Amount Spent on Website = £0.59

Therefore:

Amount Spent on Advertising : Amount Spent on Website

= 1 : 0.59

Multiply both sides by 100

= 100: 59

The ratio of the amount spent on advertising to its website as a ratio in its simplest form is 100:59 in its simplest form.

Answer:

£100 : £59

Step-by-step explanation:

The said company spends £0.59 on its website for every pound spent on advertisement. This implies that out of £1.00 spent on advertisement by the company, £0.59 is for website placements.

Thus, the rate of the amount spent on advertisement to amount spent on website is given as:

             £1.00 : £0.59

To convert this to the nearest whole number, multiply through by 100, so that the ratio becomes;

£100.00 : £59.00

Therefore, the ratio expressed in its simplest form is £100 : £59

We are expected to find 1,080,000 right handed people in that group of people

Step-by-step explanation:

In this question, we are given the ratio of right handed to left handed people and we are asked to calculate the number of right handed people we can find in a given population.

First, we check the ratio given.

The ratio is said to be that of left handed individuals to right handed individuals and this sits at 2 to 9.

Thus out of 1,320,000 people , the number of right handed individuals will be ;

9/(2+9) * 1,320,000

9/11 * 1,320,000

= 1,080,000 people

Answer:

99.5

Step-by-step explanation:

Answer:

9

Step-by-step explanation:

Given that

Spending done by Miranda each time while go to the store = $7

Spending done by Savannah each time while go to the store = $9

For computing the least possible number we need to take the least common multiple of $7 and $9 i.e to be $63

Now the lease possible number for Miranda has been to the store is

[tex]= \frac{ Lease\ common\ multiple}{Spending\ done \ by\ miranda}[/tex]

[tex]= \frac{\$63}{\$7}[/tex]

= 9

Or we can do one thing as we know that 7 is a prime number which is not cut by any other number except one while the 9 factor could be [tex]= 3\times 3[/tex]

Therefore the 9 times would be considered
