-1/2y
-2y

Answer:

243 divided by 3 equals 81 so r=81

Step-by-step explanation:

Answer:

81

Step-by-step explanation:

Simplify the equation. 3r=243, so divide 3 on both sides, and you get r=81, hence 81 is the answer.

Answer:

1/3

Step-by-step explanation:

y = −3x −2

This is in the form  y = mx+b  where m is the slope

This line has a slope of -3

We want the slope of a line that is perpendicular

Lines that are perpendicular have slopes that are negative reciprocals

m = -(1/-3)

m = + 1/3

The slope  of a line that is perpendicular is 1/3

Answer:

to find the WX you have to use this formula

m>S=TR-WX/2

45=116-WX/2

90=116-WX

WX=116-90

WX=26

the answer is D 26

Answer:

D

Step-by-step explanation:

The secant- secant angle WSX is half the difference of the intercepted arcs, that is

[tex]\frac{1}{2}[/tex] (116 - WX)° = 45° ( multiply both sides by 2 to clear the fraction )

116 - WX = 90° ( subtract 116° from both sides )

- WX = - 26° ( multiply both sides by - 1 )

WX = 26° → D

Answer:

7/100

Step-by-step explanation:

Find the GCD (or HCF) of numerator and denominator

GCD of 70 and 100 is 10

Divide both the numerator and denominator by the GCD

70 ÷ 10

100 ÷ 10

Reduced fraction:

7

10

Therefore, 70/100 simplified to lowest terms is 7/10.

Answer:

12 miles

Step-by-step explanation:

Let

x = number of miles

Taxi A:

5 + 0.25x

Taxi B:

2 + 0.5x

In how many miles will the cost of Taxi B will be the same than Taxi A

Equate cost of taxi A and taxi B

5 + 0.25x = 2 + 0.5x

Collect like terms

5 - 2 = 0.5x - 0.25x

3 = 0.25x

Divide both sides by 0.25

3 / 0.25 = 0.25x / 0.25

x = 3/0.25

x = 12 miles

x = number of miles = 12 miles

Answer:

in the picture there's the steps

Answer:

Step-by-step explanation:

since they are similar triangle use this ratio

AB/DE=AC/DF

4/12=8/3(x+1)

do cross multiplication

12*8=3*4(x+1)

96=12(x+1)

96=12x+12

96-12=12x

84/12=x

7=x

substitute the value of x

3(x+1)

3(7+1)

3*8

24

Answer:

(3x - 5)/4

Step-by-step explanation:

(3x - 5)/4 desribes five less than thrice a number x over four. Please let me know if this is what you mean.

Answer:

4w = 25

w= 6.25

Step-by-step explanation:

We know that w + w + w + w is the same as 25 because the scale is balanced.

This is writted as 4w = 25

To solve for w, divide both sides by 4:

(4w)/4 = 25/4

w = 25/4

w = 6.25

Answer: hello your question has some missing data below is the missing data

There have been 2 attempts on the northern route from Maine to Washington. Both of those riders made it 2,000 miles and quit in Montana. There have been 19 attempts on the central route from Virginia to California; 9 of those riders didn't make it out of Virginia and the other 10 made it all the way to the Pacific. There have been 32 attempts on the southern route from Florida to San Diego. One of those riders made it the whole way. Another realized he was out of shape, and quit before he even started. The other 30 riders quit somewhere in Texas. They were evenly distributed between 1 , 300 and 1 , 700 miles. For the northern route, the median distance covered will be the mean. For the central route, the median distance covered will be the mean. For the southern route, the median distance covered will likely be the mean

answer : Doug should choose the Central route

Step-by-step explanation:

Number of Available routes = 3

Northern route ; Total distance covered =  2000 miles

Central route : Total distance between Virginia and California = 2818.5 miles

percentage of success = 10 / 19 * 100 = 52.63 %

Mean distance covered = 2818.5 * 52.63% = 1483.38 miles

southern route  

Distance to be covered = 2,548 miles

number of attempts = 32

percentage of success = 1 = ( 1 / 32) * 100 = 3.12%

median distance covered by 30 riders = 1300 + ( 400 / 30 ) = 1313.33

Conclusion :

Doug should choose central route because it has the highest percentage of success and longest distance covered  ( i.e. closest to 3000 miles ) and it is also coast to coast

Answer: Its the first one

Answer:

V = 696.91

Step-by-step explanation:

Volume of a sphere formula:

V = 4/3πr³

Given:

d = 11

r = d/2

r = 5.5

Work:

V = 4/3πr³

V = 4/3π(5.5)³

V = 4/3π(166.375)

V = 696.91

Answer:

x = ±3 (Option 3)

Step-by-step explanation:

[tex]\frac{x}{3} = \frac{3}{x}[/tex]

[tex]=> \frac{x}{3} \times 3 = \frac{3}{x} \times 3[/tex]

[tex]=> x = \frac{9}{x}[/tex]

[tex]=> x \times x = \frac{9}{x} \times x[/tex]

[tex]=> x^2 = 9[/tex]

[tex]=> \sqrt{x^2} = \sqrt{9}[/tex]

[tex]=> x = (+3) \: or \: (-3)[/tex]

∴ x = ±3

Answer:

No solution

Step-by-step explanation:

2x - y = 8

2x - y = 6

They are the same unknown variable, if they equate different things, there is a problem.

bcs 2x-y - (2x - y) = 2x - 2x - y + y = 0

but 8-6 ≠ 0

Thus this is unsolvable.

Answer: Choice A) Solar energy; renewable

The image shows panels that convert solar energy to electricity. This is an example of using  renewable   sources.

This is in contrast to something like coal energy which is nonrenewable. Coal is finite and will run out some day, unlike the sun's energy which won't run out any time soon. Sure it will eventually die off in about 5 billion years or so, but that timescale is much longer compared to the amount of coal is left. So this is a benefit to using renewable resources.

Answer:

11,73 cm (round to the nearest hundredths) ; 112 degrees

Step-by-step explanation:

circumference = 2 x radius x π = 2 x 6 x π = 37,699112 cm

measure of the arc =

37,699112 : 360 = x : 112

x = (112 * 37,699112)/360 = 11,728613 cm

the measure of the angle is given = 112 degrees

Answer:

13 miles

Step-by-step explanation:

The shortest distance would be a straight line between the two points.  This would be a hypotenuse of a right triangle

We can use the Pythagorean theorem to determine the length

a^2+b^2=c^2

5^2 +12^2 = c^2

25+144= c^2

169 = c^2

Taking the square root of each side

sqrt(169) = sqrt(c^2)

13 = c

Answer:

x= 26 y = 49

Step-by-step explanation:

let the first number be x and second be y

then

according to the question,

x + y= 75

x + (2x- 3) = 75

x + 2x - 3 = 75

3x = 75 +3

3x = 78

x = 78/3

x = 26

thus first number is 26

and second number is 2x-3=2×26-3

= 52 - 3= 49
