12. Find m please help.

Answers

Answer 1

Answer:

m<ADE = 59°

Step-by-step explanation:

Each angle of a rectangle = 90°

Therefore:

m<ABE + m<CBE = 90°

(4x + 15)° + (13x + 7)° = 90°

Solve for x

4x + 15 + 13x + 7 = 90

17x + 22 = 90

17x = 90 - 22

17x = 68

x = 68/17

x = 4

✔️Opposite sides (AB and DC) of the rectangle are parallel, therefore:

m<ADE = m<CBE

m<ADE = (13x + 7)° (Substitution)

Plug in the value of x

m<ADE = 13(4) + 7

m<ADE = 52 + 7

m<ADE = 59°

Find the distance from the point P(4,1) to the line segment joining the points Q(1,-8) and R(-4,2). Show your steps.

Answers

Answer:

7,8

Step-by-step explanation:

Distance Formula:

The distance between two points is the length of the path connecting them. The shortest path distance is a straight line. In a 2 dimensional plane, the distance between points (X1, Y1) and (X2, Y2) is given by the Pythagorean theorem:

d=(x2−x1)2+(y2−y1)2−−−−−−−−−−−−−−−−−−√

Calculate Distance

To calculate the distance between 2 points, (X1, Y1) and (X2, Y2), for example, (5, 6) and (-7,11), we plug our values into the distance formula:

d=(−7−5)2+(11−6)2−−−−−−−−−−−−−−−−−√

combining terms inside parentheses we get:

d=(−12)2+(5)2−−−−−−−−−−−√

squaring both terms we get,

d=144+25−−−−−−−√

adding the 2 results,

d=169−−−√

finally,

d=13

2x + y = 12
y-2 = 3(x - 2)
1) parallel
2) perpendicular
3) the same line
4) neither parallel nor perpendicular

Answers

Answer:

Step-by-step explanation:

2x+y=12

y=-2x+12

y-2=3(x-2)

If it’s parallel to each other: the slope has to be the same.

If is perpendicular to each other: the slope should be the reciprocal to each other.

The first equation has a slope of -2

The second has a slope of 3

Neither the condition meet. So the answer is 4

Think about multiplying any two rational numbers. Based on this activity and your previous work, write a set of rules for finding the sign of the product based on the sign of the two numbers being multiplied.

Answers

Answer:

Positive (+) * positive (+) = +

Negative (-) * negative - = +

Negative (-) * positive (+) = -

Positive (+) * negative (-) = +

Step-by-step explanation:

How result of the product of two numbers are affected by the sign on each number being multiplied :

Signs on number values may be positive (+) or negative (-)

The rules goes thus :

Positive (+) * positive (+) = +

Negative (-) * negative - = +

Negative (-) * positive (+) = -

Positive (+) * negative (-) = +

Therefore for any tow rational numbers, the sin of their product will follow the rules above.

Answer:

See Explanation

Step-by-step explanation:

Let us assume that [tex] 5\sqrt 7[/tex] is a rational.

Therefore, it can be expressed in the form of [tex] \frac{p}{q}[/tex], where p and q are integers.

[tex] \implies 5\sqrt 7=\frac{p}{q}[/tex]

[tex] \implies \sqrt 7=\frac{p}{5q}[/tex]

[tex] \because [/tex] p and q are integers.

[tex] \therefore \frac{p}{5q}[/tex] is a rational number.

[tex] \implies \sqrt 7[/tex] is rational ([tex] \because [/tex] quotient of a rational number is rational)

But, it contradicts the fact that [tex]\sqrt 7[/tex]is irrational.

So, [tex]5\sqrt 7[/tex] is also irrational, because the product of rational and irrational is irrational.

This contradiction is arising out because of our wrong assumption that [tex] 5\sqrt 7[/tex] is rational.

Hence, [tex] 5\sqrt 7[/tex] is irrational.

Answers

Answer:

Becky ran farther and farther by 560 ft.

Step-by-step explanation:

1 mile = 5280 ft

Becky: 2 * 5280 = 10560 ft

Keith: 10000 ft

10560 ft > 10000 ft, so Becky ran more distance than Keith.

10560 - 10000 = 560 ft, so Becky ran 560 ft more than Keith.
