Answer:

Step-by-step explanation:

Answer:

In order to determine if two lines are parallel, perpendicular, or neither, look at their slopes. If the lines have the same slope, they are parallel. If the slopes are opposite reciprocals, then they are perpendicular. If the slopes of the lines are not any of those, then they are neither.

Parallel line: [tex]y = \frac{2}{5} x[/tex]

Perpendicular line: [tex]y = -\frac{5}{2} x[/tex]  

Neither: [tex]y = 3x[/tex]

Step-by-step explanation:

In order to determine if two lines are parallel, perpendicular, or neither, look at their slopes. If the slopes of the two lines are the same, then they are parallel. If the slopes of the two lines are opposite reciprocals, then they are perpendicular. If the slopes of the lines are not any of those, then they are neither.  

The equation [tex]y = \frac{2}{5} x+7[/tex] is in slope-intercept form. The y is isolated and it's in [tex]y = mx + b[/tex] format. Whenever an equation is in slope-intercept form, the [tex]m[/tex], or the coefficient of the x-term, represents the slope. So, the slope of the given line is [tex]\frac{2}{5}[/tex]. Therefore, use the rules listed previously to find lines that are parallel and perpendicular.

Parallel lines have the same slope, so an example of a parallel line would be [tex]y = \frac{2}{5} x[/tex].

Lines that are perpendicular have slopes that are opposite reciprocals, so an example of a perpendicular line would be [tex]y = -\frac{5}{2} x[/tex].

Lines that are neither do not fall into either of those categories, so an example of a line that is neither would be  [tex]y = 3x[/tex].

Answer:

y=18 x=15

Step-by-step explanation:

1.

multiplyboth sides by 3

2(x-6)=18

divide both sides by 2

x-6= 9

add 6 on both sides

x=15

2.

add 6 on both sides

2/3y= 12

multiply both sides by 3

2y=36

divide both sides by 2

y=18

Step-by-step explanation:

4x -20 + 3x +12 = 90

7x -8 = 90

7x = 98

x = 14

Angle F: 4(14) -20 = 36

Angle E: 3(14)+12= 54

Angle G : 90

The answer for the following question is 0.7

Answer: 0.7

Step-by-step explanation:

Answer and Step-by-step explanation:

First, get theta by itself.

θ = [tex]sin^{-1}(\frac{\sqrt{3} }{2} )[/tex]

Plug this into a calculator.

θ = 60°

To get it in radians, multiply 60 by [tex]\frac{\pi }{180}[/tex].

θ = [tex]\frac{1}{3} \pi[/tex] radians

Answer:

I think the strawberry cake measure have to be 360⁰. so the arc measure is 360⁰÷3=100

so we have all three arcs congruent b/c all measures 100⁰

I think XYZ=100⁰

Step-by-step explanation:

solution given:

a strawberry cake is cut into three pieces

since

Arc measures of all three pieces are congruent

all 3 arc are equal

So it forms a equilateral TRIANGLE

each angle of equilateral triangle is 60°

So,measure of angle XYZ is 60°.

Answer: 240 mangoes

Explanation:

1/5 + 0.75 = .95 = 95%

5% = 12

50% = 120

100% = 240

*☆*――*☆*――*☆*――*☆*――*☆*――*☆*――*☆*――*☆**☆*――*☆*――*☆*――*☆

Answer:

240

Step-by-step explanation:

1/5

0.75 = 3/4

1/5 + 3/4 = 19/ 20

1 - 19/20 = 1/20

therefore 12 mango equal 1/20

12 × 20 = 240

12/240 is the same as 1/20

Step-by-step explanation:

Answer:

Average time for West Middle was maximum.

Step-by-step explanation:

Average time for a track meet for schools = [tex]\frac{\text{Time}}{\text{Distance}}[/tex]

For Eastbay Middle,

Average time per mile = [tex]\frac{42}{7}[/tex]

                                     = 6 minutes per mile

For Northwest Middle,

Average time = [tex]\frac{25}{5}[/tex]

                       = 5 minutes per mile

For South Central Middle,

Average time = [tex]\frac{28}{4}[/tex]

                       = 7 minutes per mile

For West Middle,

Average time = [tex]\frac{48}{6}[/tex]

                       = 8 minutes per mile

Therefore, average time for West Middle (8 minutes per minute) was maximum.

Step-by-step explanation:

In triangle ABD,

ang.ABD=90°

AB=9 cm

AD=15 cm

Now,

Using Pythagoras theorem,

AD2=AB2+BD2(2=square)

or,152=92+BD2

or,225=81+BD2

or,225-81=BD2

or,144=BD2

or,BD=12 cm

Then,

In triangle CBD,

CD=5 cm

BD=12 cm

BC=?

Now,

Using Pythagoras theorem,

BC2=CD2+BD2

or,BC2=52+122

or,BC2=25+144

or,BC2=169

or,BC=13 cm

Answer:

128/15 minutes or 8.5 minutes

Step-by-step explanation:

By using unitary method, Time required to paint 5/8 of wall = 16 minutes.

Time required to paint 1/1 of wall = 16*8/5

Hence, Time required to paint 1/3 of wall = 16*8/5*1/3

Hope this helps, thank me later

8.53 minutes

Step-by-step explanation:

Answer:

√(64÷√(98 = (4√2)/7

Step-by-step explanation:

The Sqrt(64) is equivalent to 8

And the Sqrt(98) is equivalent to Sqrt(49) x Sqrt(2) also known as 7 Sqrt(2)

Now since we can't have a Square Root at the denominator we multiply it by Sqrt(2) on both the numerator and denominator

We now have 8Sqrt(2)/14 which can be simplified to (4√2)/7

Answer: $20,000

Step-by-step explanation:

Given

Interest decreases from 3.75% to 3.5% in a year

This change in the rate of interest brings a yield of 50$

Earlier interest was

[tex]S.I_e=\dfrac{P\times 3.75\times 1}{100}[/tex]

Now, interest is

[tex]S.I._n=\dfrac{P\times 3.5\times 1}{100}[/tex]

change gives 50$ i.e.

[tex]\Rightarrow \dfrac{P\times 3.75\times 1}{100}-\dfrac{P\times 3.5\times 1}{100}=50\\\\\Rightarrow \dfrac{P\times (3.75-3.5)\times 1}{100}=50\\\\\Rightarrow P=\dfrac{50\times 100}{0.25}=\$20,000[/tex]

Answer: The probability that at least one of the envelopes is red is 1/9 (simplified) or 9/81.

Step-by-step explanation:

There are a total of 9 envelopes. If two are selected at random with replacement the probability for both envelopes is 3 / 9 or 1/3. Since there are two you would do 1/3 * 1/3 to get 1/9 or 3/9 * 3/9 to get 9/81.
