Which equation shows y=-1/2x +4 is in standard form?

Answer:

Italy Time is in the Central European Time Zone . Central European Standard Time ( CET ) is 1 hours ahead of Greenwich Mean Time ( GMT+1 ).

Step-by-step explanation:

Central European Time Zone

Italy's time zone is one hour ahead of GMT (Greenwich Mean Time), so if it is 1 PM GMT, it would be 2 PM in Italy. This reflects the Time Zone Difference concept.

If Italy's time zone is GMT + 1, and it is currently 1 PM GMT, then the time in Italy would be 2 PM. This is due to the fact that Italy is one hour ahead of GMT (Greenwich Mean Time). Therefore, to convert from GMT to Italy's time zone, one simply needs to add one hour. For example, if it was 5 PM in GMT, it would be 6 PM in Italy, and so on. This concept is referred to as Time Zone Difference.

Answer:

8 ft²

Step-by-step explanation:

Since ΔEFG ~ ΔABC, they are proportionately related. Each of the corresponding sides differ by the scale factor, which shows how much bigger or smaller the new triangle is from the original triangle.

Purple = original triangle, triangle 1

Pink = new triangle, triangle 2

Find the scale factor, "k". It will be a fraction because the triangle gets smaller.

k = FG/BC = 2/3

The scale factor can be used to find a side, the height or the area of the new triangle.

Use the scale factor squared to find the area.

A₂ = (A₁)(k²)

= (18 ft²)(2/3)²

= 7.999...ft²

= 8 ft²

Answer:

[tex]\frac{2}{5}[/tex]

Step-by-step explanation:

The total length of this line is 15 units. FG is 6 units long.

This means that the probability of p being on FG would be [tex]\frac{6}{15}[/tex] which can be simplified to [tex]\frac{2}{5}[/tex]

Answer:

2/5

Step-by-step explanation:

Line EH has three line segments:

EF which measure 4

FG which measures 6

GH which measures 5

The total measure of the line (EH) = 4 + 6 + 5 = 15

So if we are calculating the probability of landing on FG,

6 / 15

Reduce the fraction to make,

(a) m=6h+15 can be used to find the total amount of money for h hours of babysitting.

(b) After 6 hours of babysitting, Scott will have $51.00

Step-by-step explanation:

Given,

Amount Scott has = $15.00

Per hour amount of babysitting = $6.00

a) Write an equation for the amount of money (m) Scott has after a number of hours babysitting (h).

Total amount of money = m

Number of hours babysitting = h

Total amount of money = Per hour earning from babysitting*Number of hours + Amount Scott has

[tex]m=6h+15[/tex]

m=6h+15 can be used to find the total amount of money for h hours of babysitting.

b) After how many hours of babysitting will Scott have $51.00?

Putting m = 51

[tex]51=6h+15\\51-15=6h\\36=6h\\6h=36[/tex]

Dividing both sides by 6

[tex]\frac{6h}{6}=\frac{36}{6}\\h=6[/tex]

After 6 hours of babysitting, Scott will have $51.00

#LearnwithBrainly

Final answer:

To find the actual distance from Los Angeles to San Diego, multiply the map distance (6.35 cm) by the scale conversion factor (20 miles per cm), resulting in an actual distance of 127 miles.

Explanation:

The question deals with calculating the actual distance between Los Angeles and San Diego, given the scale on the map and the measured distance. To find the actual distance, you multiply the distance on the map by the conversion factor provided by the scale. In this case, the scale is 1 cm for every 20 miles. The measured distance on the map is 6.35 cm.

Therefore, the actual distance between Los Angeles and San Diego is calculated as follows:

Actual distance = Map distance × Scale conversion factor

Actual distance = 6.35 cm × 20 miles/cm

Actual distance = 127 miles

The actual distance from Los Angeles to San Diego is 127 miles.

Answer:

option 3 ⇒ f⁻¹(x) =  [tex]\frac{x^{2} -2 }{3} [/tex]

Step-by-step explanation:

Given F(x) = [tex]\sqrt{3x+2}[/tex]

let y = f(x)

y = [tex]\sqrt{3x+2}[/tex]   ⇒ squaring the both sides

y² = 3x + 2  ⇒ subtract 2 from both sides

y² - 2 = 3x ⇒ divide both sides by 3

[tex]\frac{y^{2} -2 }{3} = x[/tex]

replace the location of x and y

∴ y = [tex]\frac{x^{2} -2 }{3} [/tex]

So, y will be f⁻¹(x)

∴ f⁻¹(x) =  [tex]\frac{x^{2} -2 }{3} [/tex]

The measure of the angle formed with the positive x-axis and the equation of the given line is 51° to the nearest degree

Step-by-step explanation:

The formula to find the angle between the positive part of x-axis and a line y = m x + b is tan(Ф) = m, where

∵ The equation of the line is [tex]y=\frac{5}{4}x[/tex]

∵ The form of the equation of a line is y = m x + b

∴ m = [tex]\frac{5}{4}[/tex] and b = 0

∵ Ф is the angle between the line and the positive part of x-axis

∵ tan(Ф) = m

∴ tan(Ф) = [tex]\frac{5}{4}[/tex]

- To find Ф use the inverse function of tan ( [tex]tan^{-1}[/tex]

∵ Ф = [tex]tan^{-1}(\frac{5}{4})[/tex]

∴ Ф = 51.34°

- Round it to the nearest degree

∴ Ф = 51°

Answer:

[tex]3a^4[/tex]

Step-by-step explanation:

What is the cube root of  [tex]27a^{12}[/tex]? This is the question.

We can write:

[tex]\sqrt[3]{27a^{12}}[/tex]

We will use the below property to simplify:

[tex]\sqrt[n]{a*b}=\sqrt[n]{a}  \sqrt[n]{b}[/tex]

So, we have:

[tex]\sqrt[3]{27a^{12}} =\sqrt[3]{27} \sqrt[3]{a^{12}}[/tex]

We will now use below property to further simplify:

[tex]\sqrt[n]{x} =x^{\frac{1}{n}}[/tex]

Thus, we have:

[tex]\sqrt[3]{27} \sqrt[3]{a^{12}} =3*(a^{12})^{\frac{1}{3}}[/tex]

We know power to the power rule:  [tex](a^z)^b=a^{zb}[/tex]

Now, we have:

[tex]3*(a^{12})^{\frac{1}{3}}\\=3*a^{\frac{12}{3}}\\=3a^4[/tex]

This is the correct answer:  [tex]3a^4[/tex]

Answer:

e) Shamika= 224 balloon, Crystal= 112 balloon, Aliya= 114 Balloon.

f)  We know,Crystal sold "b" balloon

           Aliya sold (b+2) balloon

          Shamika sold 2b balloon.

As per data given in question part c that each balloon cost $2 and Total cost of balloon is $900.

Now, solving to find how much each student sold balloon at school´s winter dance.

As we know total cost is $900 and each balloon cost is $2.

∴ Total cost= [tex]Total\ quantity \times cost\ of\ each\ unit[/tex]

Total quantity= [tex]{b+(2+b)+2b}[/tex]

∴ [tex]\$ 900= {b+(2+b)+2b}\times \$ 2[/tex]

Once we solve, we will get the value of b as 112 balloon, which is the number of balloon sold by Crystal.

Substituting the value of b in the equation of Aliya and Shamika, we will get the number of balloon sold by them.

Which is 114 and 224 respectively.

Step-by-step explanation:

Given: Crystal sold "b" balloon

           Aliya sold (b+2) balloon

          Shamika sold 2b balloon.

As per data given in question part c that each balloon cost $2 and Total cost of balloon is $900.

Now, solving to find how much each student sold balloon at school´s winter dance.

As we know total cost is $900 and each balloon cost is $2.

∴ Total cost= [tex]Total\ quantity \times cost\ of\ each\ unit[/tex]

Total quantity= [tex]{b+(2+b)+2b}[/tex]

∴ [tex]\$ 900= {b+(2+b)+2b}\times \$ 2[/tex]

Opening the parenthesis.

⇒[tex]\$ 900= (b+2+b+2b)\times \$ 2[/tex]

⇒[tex]\$ 900= 2+4b \times 2[/tex]

Dividing both side by 2

⇒ [tex]\$ 450= 2+4b[/tex]

Subtracting both side by 2

⇒ [tex]\$ 448= 4b[/tex]

Cross multiplying

∴[tex]b= \frac{448}{4} = 112[/tex]

∴ b= 112.

Hence, we can say Crystal have sold 112 balloons.

Next subtituting the  value of "b" in the equation for Aliya and Shamika to get number of balloon they have sold.

We know, Aliya sold b+2 balloons

∴ Aliya sold= [tex]112+2= 114\ balloon[/tex]

Aliya sold 114 balloon.

We know, Shamika sold 2b balloons

∴[tex]2\times 112= 224 balloon.[/tex]

Shamika sold 224 balloon.

Step-by-step explanation:

Given: Orlando work at $6/h in first week and at $7/h in second week.

           Total earning is $347 in both weeks.

Let the number of hours Orlando work in first week be`x` hours

∴ working hours in second week is (x+5) hours

Now, solving to find the number of working hours.

⇒ Total earning= earning in first week+earning in second week.

⇒ [tex]\$ 347= x\times 6+(x+5)\times 7[/tex]

Opening the parenthesis and solving it.

⇒ [tex]\$ 347= 6x+7x+35[/tex]

Subtracting both side by 35

⇒ [tex]312= 13x[/tex]

∴ x= [tex]\frac{312}{13} = 24\ h[/tex]

∴ Working hours in first week is 24 hours

   Working hours in second week is [tex]24+5= 29\ h[/tex]

To prove congruence by SSS, two statements are needed about equal sides: AC―――― ≅ ED―――― and DE―――― ≅ BC――――. A third unlisted statement equating the other sides is also required.

To prove two triangles are congruent using the Side-Side-Side (SSS) Postulate, we need to establish that all three corresponding sides of the triangles are equal in length. Statement B indicates that AC―――― ≅ ED――――, which provides one pair of corresponding sides. Statement C suggests that DE―――― ≅ BC――――, providing a second pair of corresponding sides. Lastly, if we had information that AB―――― = DF――――, not provided in the options but necessary to complete the SSS congruence, then we could establish the congruence of the two triangles. Therefore, the statements needed for SSS congruence proof are options B and C, along with an unlisted statement that equates the third pair of corresponding sides.

Answer:

x = 31°

Step-by-step explanation:

Since, CB ║ FG and AB is a transverse, so ∠ BAG = ∠ ABC = 28° {Alternate angles}

Now, ∠ CAG = 90° = ∠ CAD + ∠ BAG

⇒ ∠ CAD = 90° - 28° = 62°

From, Δ ADE, ∠ ADE + ∠ DEA + ∠ EAD = 180°

⇒ ∠ ADE = 180° - 62° - 3x = 118° - 3x.

Now, ADB being a straight line, so ∠ ADE + ∠ EDC + ∠ CDB = 180°

⇒ 118 - 3x + x + 4x = 180

⇒ 2x = 62

⇒ x = 31° (Answer)

Step-by-step explanation:

Given:-

Total distance to travel (D) = 2598 miles.

Distance travelled (d) = 683 miles.

To calculate = remaining distance (r) to complete trip.

Remaining distance = Total distance minus Distance travelled

i.e.  [tex]r=D-d[/tex]

[tex]r=2598-683[/tex]

[tex]r=1915\ miles[/tex]

Therefore kalsbeeks have to travel 1915 miles more to complete their trip.

Answer:

[tex]sin \theta =\frac{-8}{10} =-\frac{4}{5}[/tex]

Step-by-step explanation:

For this case we have a point given (-6,-8) and we know that this point is terminal side of 0​

We can assume that the length of th opposite side is given by:

b=-8 and the length for the adjacent side would be a=-6

And we can find the hypothenuse on this way:

[tex] c= \sqrt{a^2 +b^2}=\sqrt{(-6)^2 +(-8)^2}=10[/tex]

From the definition of sin we know this:

[tex]sin O =\frac{opposite}{hypothenuse}[/tex]

And if we replace we got this:

[tex]sin \theta =\frac{-8}{10} =-\frac{4}{5}[/tex]

We can aslo find the cos with the following identity:

[tex]cos^2 \theta + sin^2 \theta = 1[/tex]

And then:

[tex]cos \theta = \pm \sqrt{1-sin^2 \theta}=\pm \sqrt{1- (-4/5)^2}=\pm \frac{3}{5}[/tex]

But since both corrdinates are negative we are on the 3 quadrant and then [tex]cos \theta= -\frac{3}{5}[/tex]
