Answer:

3. 151°

Step-by-step explanation:

Since m and n are parallel, therefore:

m<1 + 75° = 180° (consecutive exterior angles are supplementary)

Subtract 75 from each side

m<1 = 180 - 75

m<1 = 105°

m<2 = 46° (corresponding angles are congruent)

Sum of <1 and <2 = 105° + 46° = 151°

Answer:

COULD BE Y=6x-8

Step-by-step explanation:

Answer:

y=6x-8

Step-by-step explanation:

I'm using the y=mx+b formula. m always represents the slope, and b the y-intercept. So all I did was plug the numbers in. (This can help with determining the slope and y-intercept as well, btw)

Answer: 4 inches

Step-by-step explanation:

From the question, we are informed that Last year during the hurricane season, the amount of rain that fell on the Texas Gulf Coast in October was 14 inches, which was 3 1/2times more than the rainfall during September of the same year.

The amount of rain that fell during the month of September can be calculated as:

= 14 inches ÷ 3 1/2

= 14 ÷ 7/2

= 14 × 2/7

= 28/7

= 4 inches

The rain that fell during the month of September was 4 inches.

Answer:

1/b

Step-by-step explanation:

b=b/1. 1/b would be a reciprical because it switches the numberator and denominator.

Answer:

Step-by-step explanation:

10000*4%= 400 Geese year1

10400*4%=416 Geese  year 2

10816*4%= 432.64 Geese year 3

11,248.64*4%= 449.95 Geese. year 4

11248.64+449.95= 11698.59

11698.59-10000=1698.59

Increased by 1699 Geese.

Answer:

Orge has $50 left in his checking account.

Step-by-step explanation:

Answer:

There is a total 50 questions.

Step-by-step explanation:

Let x = total questions in the exam

Since 82% of the test was scored correctly, that means 18% of the student's exam was scored incorrectly.

With this information we can write:

[tex]18\%x=9[/tex] (Given that the student made 9 mistakes)

[tex]x=9\div18\%[/tex] (divide 18% on both sides)

[tex]x=50[/tex]

∴ There was a total of 50 questions in the examination.

Answer:

x=4 degrees

Step-by-step explanation:

its an equilateral triangle so all sides are equal, if one angle is 10x+20,then the rest are each 10x+20.This is a triangle and it adds up to 180 degrees. So in total, (10x+20)×3=30x+60.So you do this, 30x +60=180 degrees, you take the sixty to the other side and subtract it from 180 ,you'll get 120 degrees, then divide 120by 30x

Step-by-step explanation:

the dog is approximately 55 pounds and we know 1 kg is approximately 2.2 pounds. 55 divided by 2.2 is 25. the dog is approximately 25 kg.

Answer:

19

Step-by-step explanation:

Answer:

y=19

Step-by-step explanation:

your equation is y=6x-11 with an input of 5 so you plug in 5 for x.

% times 6 is 30 and 30 minus 11 is 19

Answer: 13

Step-by-step explanation:

Answer:

[tex]y = \frac{1}{2} x+7[/tex]

Step-by-step explanation:

Slope-intercept form: y = mx + b

Slope formula: [tex]\frac{y2-y1}{x2-x1}[/tex]

Given points: (-6, 4), (6, 10)

(-6, 4) = (x1, y1)

(6, 10) = (x2, y2)

To write the equation in slope-intercept form, we need to find the slope(m) and the y-intercept(b) of the equation.

First, let's find the slope. To do this, input the given points into the slope formula:

[tex]\frac{10-4}{6-(-6)}[/tex]

Simplify:

10 - 4 = 6

6 - (-6) = 6 + 6 = 12

[tex]\frac{6}{12}=\frac{1}{2}[/tex]

The slope is [tex]\frac{1}{2}[/tex].

To find the y-intercept, input the slope and one of the given points(in this example I'll use point (6, 10)) into the equation and solve for b:

[tex]10 = \frac{1}{2}(6)+b[/tex]

10 = 3 + b

7 = b

The y-intercept is 7.

Now that we know the slope and the y-intercept, we can write the equation:

[tex]y = \frac{1}{2} x+7[/tex]

Answer and explanation:

The gambler's fallacy is the fallacy of belief that if an event such as a loss occurs more frequently in the past, it is less likely to happen in the future. We assume here that this belief is true, therefore

If she loses, her probability of winning increases =3/4

If she wins, her probability to win is normal =1/2

Given that probability of winning is 1/2

Probability of losing is 1-1/2=1/2

Probability that she wins the tournament is probability that she wins the first two games and loses the last or wins the first game, loses the second and wins the last or loses the first game and wins the last two games or probability that she wins all three games

=1/2*1/2*1/2+1/2*1/2*3/4+1/2*3/4*1/2+1/2*1/2*1/2

=25/48

Probability of winning the tournament if she loses the first game

=1/2*3/4*1/2= 3/16

Note: whenever there is "or" in probability, you add

Answer:

b)42, x=-2

Step-by-step explanation:

Answer:

The option 'b' is correct.

Step-by-step explanation:

Given the function

[tex]f\left(x\right)\:=\:10x^2\:+\:40x\:+\:42[/tex]

Determining the y-intercept

The y-intercept can be obtained by setting the value x = 0

[tex]y\:=\:10x^2\:+\:40x\:+\:42[/tex]

[tex]y\:=\:10\left(0\right)^2\:+\:40\left(0\right)\:+\:42[/tex]

    [tex]= 0+0+42[/tex]

    [tex]=42[/tex]

Therefore, the y-intercept is:

Determining the axis of symmetry

Given the equation

[tex]y=\:10x^2\:+\:40x\:+\:42[/tex]

For a parabola in standard form [tex]y=ax^2\:+\:bx\:+c[/tex]

the axis of symmetry is the vertical line that goes through the vertex

[tex]x=\frac{-b}{2a}[/tex]

so

The  axis of symmetry for [tex]y=ax^2\:+\:bx\:+c[/tex]  is [tex]x=\frac{-b}{2a}[/tex]

[tex]a=10,\:b=40[/tex]

[tex]x=\frac{-b}{2a}[/tex]

[tex]x=\frac{-40}{2\cdot \:10}[/tex]

[tex]x=-2[/tex]

Therefore, the option 'b' is correct.

Answer:

To the nearest percentage, percent increase is 33%

Step-by-step explanation:

Mathematically;

Percentage increase = (new - old)/old * 100%

new = 48 hours

old = 36 hours

% increase = (48-36)/36 * 100%

12/36 * 100%

1/3 * 100%

= 33.33%

Answer: 33% increase
