here's all my points plz help

a^2 + b^2 =c^2

1^2 + 2^2 = 1+4 = 5

so no it doesn't make a right triangle

Answer:

1. Non equivalent, use the distributive property. 5*3=18, 5*4=20, so the equation is now 18y - 20, which is not equal to 15y - 20

2. Same with this one, -4 * -2p = 8p, and  -4 * 4 = -16. Now the equation is 8p - (-16), or 8p + 16. Not equivalent.

3. 3*-7x = -21x, and 3*13 = 39. Now the equation is -21x - 39, not equivalent.

4. -6*-4a = 24a, and -6*8 = -48, the equation is now 24a+ (-48), or 24a - 48

I did my best, and I am confident in the answers, but I apologize if I am wrong.

Answer:

0.32

.22

regular (capuccino is incorrect)

Step-by-step explanation:

in the mocha column 25 people prefer hot and 12 people prefer cold are equal to 37 people.  25+12=37

relative frequency of preferring cold is 12.  12÷37 = .32

In the hot column 11, 25, 19, 30 people are combined for total of 85 people who prefer hot coffee.  11+25+19+30=85

relative frequency of preferring a latte is 19: 19÷85 = .22

combine regular column for 17 ÷ 28 = .61

combine mocha column for 12÷40 = .30

combine latte column for 20÷39 = .51

combine cappucino column for 27÷57 = .47

The type of coffee that has the highest percentage of people who prefer it cold is regular.  (if you combine only the cold column you will end up with cappuccino which is wrong.)

Answer:

1.26 but rounded to the nearest 10 would be 1.3 so 1.3 is your answer

Step-by-step explanation:

Answer:

x=4, y=-2

Step-by-step explanation:

-5x+8y=-36

5x+7y=6

eqn 1+ eqn 2 gives

15y=-30

divide both sides by 15

y=-2, put in eqn 2

5x+7(-2)=6

5x=20 divide both sides by 5

x=4

Answer:

It is between A and D, all the problem is about predictions and how this predictions are tricked.

Step-by-step explanation: Just make some draws of the number and colors of the marbles, and add the white marbles to the red ones, there is 6 of them, they take out of the bag two, so there are still being four, a hundred is all a number (?) so divided 100 % in 4/ there is 25, is D just take D. Sorry man im tired.

1=0.5

2=0.9

3=1.3

4=1.7

5=2.1

6=2.5

7=2.9

8=3.3

9=3.7

10=4.1

Answer:

The answer is 23

Step-by-step explanation:

0.5, 0.9, 1.3, 1.7, 2.1, 2.5, 2.9, 3.3, 3.7, 4.1

Answer: 110 degrees

Since the 2 unknown angles in the triangle are equal you do (180-40)/2 to find what they are equal to. (It's equal to 70) Now that you have the answer for the two angles, now you can subtract 70 from 180 which gives you 110 degrees and that's your answer

Hope this helped you!

Answer:

x°+x°+40°=180°

2x°=180°-40°

2x°=140°

x°=140°

2

x°=70°

x°=70°

therefore,

x=180°-70°

x°=110°

Answer:

$159.75

Step-by-step explanation:

137.45/252.60 + x = 1/3

252.60 + x = 412.35

x = 412.35 - 252.60

x = 159.75

Answer:

297.2

Step-by-step explanation:

549.8 ÷ 4 = 137.45

549.8 - 252.60 = 297.2

Answer:

11,700cm²

Step-by-step explanation:

Area of the triangle = 1/2*JK sin<I

Given

J = 800cm

K = 240cm

<I = 173 degrees

Substitute

Area of the triangle = 1/2 * 800 * 240 sin 173

Area of the triangle = 400 * 240sin 173

Area of the triangle = 400 * 29.25

Area of the triangle = 11,699.5

Area of the triangle to the nearest square centimeter is 11,700cm²

Answer:

29.4%

Step-by-step explanation:

the whole cirlce is 360 degrees which means 100%

to find the percentage of the shaded area, multiply the degrees by 100

⇒ 10.6 x 100 = 10600

then take the product and divide by 360

⇒ 1060 ÷ 360

⇒ 29.44

round to the nearet tenth of a percent

⇒ 29.4

Answer:

Resultant is 50 mi/hr in the north east direction

Step-by-step explanation:

Plane is traveling north east at 150 mi/hr.

Now a wind is blowing from the south west at 100 mi/hr.

Now, north east and south west are directly opposite directions and such the angle between the resultant speed of the plane in flight and the wind will be;

150 - 100 = 50 mi/hr

Since the north east speed is greater than the south east speed, then the direction will be north east.

Thus, resultant is 50 mi/hr in the north east direction

Answer:

(3, 1.7)

Step-by-step explanation:

The point at which the vertices of a triangle meet is known as the orthocenter of the triangle. The orthocenter passes through the vertex of the triangle and is perpendicular to the opposite sides.

Two lines are perpendicular if the product of their slopes is -1.

The slope of the line joining D(0,0), F(3,7) is:

[tex]m_1=\frac{7-0}{3-0}=\frac{7}{3}[/tex]

The slope of the line perpendicular to the line joining D and F is -3/7. The orthocenter is perpendicular to the line joining D and F and passes through vertex E(7, 0). The equation is hence:

[tex]y-y_1=m(x-x_1)\\\\y-0=-\frac{3}{7} (x-7)\\\\y=-\frac{3}{7}x+3 \ .\ .\ .\ (1)[/tex]

The slope of the line joining E(7,0), and F(3,7). is:

[tex]m_1=\frac{7-0}{3-7}=-\frac{7}{4}[/tex]

The slope of the line perpendicular to the line joining E and F is 4/7. The orthocenter is perpendicular to the line joining E and F and passes through vertex D(0, 0). The equation is hence:

[tex]y-y_1=m(x-x_1)\\\\y-0=\frac{4}{7} (x-0)\\\\y=\frac{4}{7} x\ .\ .\ .\ (2)[/tex]

The point of intersection of equation 1 and equation 2 is the orthocenter. Solving equation 1 and 2 simultaneously gives:

x = 3, y = 1.7

Answer:

[tex]\theta = 30^\circ, 330^\circ[/tex]

[tex]\theta = \frac{\pi}{6}, \frac{11\pi}{6}[/tex]

Step-by-step explanation:

Given [Missing from the question]

Equation:

[tex]cos\theta = \frac{\sqrt 3}{2}[/tex]

Interval:

[tex]0 \le \theta \le 360[/tex]

[tex]0 \le \theta \le 2\pi[/tex]

Required

Determine the values of [tex]\theta[/tex]

The given expression:

[tex]cos\theta = \frac{\sqrt 3}{2}[/tex]

... shows that the value of [tex]\theta[/tex] is positive

The cosine of an angle has positive values in the first and the fourth quadrants.

So, we have:

[tex]cos\theta = \frac{\sqrt 3}{2}[/tex]

Take arccos of both sides

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

[tex]\theta = 30[/tex] --- In the first quadrant

In the fourth quadrant, the value is:

[tex]\theta = 360 -30[/tex]

[tex]\theta = 330[/tex]

So, the values of [tex]\theta[/tex] in degrees are:

[tex]\theta = 30^\circ, 330^\circ[/tex]

Convert to radians (Multiply both angles by [tex]\pi/180[/tex])

So, we have:

[tex]\theta = \frac{30 * \pi}{180}, \frac{330 * \pi}{180}[/tex]

[tex]\theta = \frac{\pi}{6}, \frac{33 * \pi}{18}[/tex]

[tex]\theta = \frac{\pi}{6}, \frac{11 * \pi}{6}[/tex]

[tex]\theta = \frac{\pi}{6}, \frac{11\pi}{6}[/tex]

Answer:

Answer choice one

Step-by-step explanation:

To find the perpendicular line to a given line, just give the reciprocal of the slope and flip the sign.

In this case, you first put the line into the slope-intercept form which would be y=2x-7.

the slope is 2x and the reciprocal is 1/2 and then you flip the sign to be -1/2.

The only one with that slope is answer choice 1.
