Solve for the length of BC

Answers

Answer:

BC= 9cm

Step-by-step explanation:

You'll need to use the Pythagorean theorem:

a^2 + b^2 = c^2

12^2 + b^2 = 15^2

The slanted side of the triangle is always going to be 'c' because it is the longest side of the triangle.

Now simplify:   144 + b^2 = 225

I got these numbers because 12^2= 144 and 15^2= 225

Subtract.   225 - 144 = 81

Now find the square root of 81. The answer is 9.

Find the slope of the line passing through the points (-18, -5) and (-19, -13)​

Answers

Answer:

Let (-18, -5) be (x1,y1)

(-19, -13) be (x2,y2)

slope = (y2-y1)/(x2-x1)= (-13+5)/(-19 +18) = 8

Answer: The slope is 8.

Step-by-step explanation: To get the slope you have to do y2 - y1 over x2 - x1. so you take the -5 and subtract -13 from it, which equals 8. Then subtract -19 from -18 which is 1. So you have 8/1 which is 8.

Let b represent the hours Liz spends babysitting. Let t represent the number of hours she spends tutoring. Given that Liz can work at most 12 hours per week, write an inequality that models the number of hours she spends babysitting and tutoring in a week.

Answers

So if b is hours for babysitting, and t is for tutoring she works 12 hours so it would be 12=b+t

Answer:

b+t < 12 (< has a line under it)

Step-by-step explanation:

Liz can work at most 12 hours per week. So, add the number of hours she spends babysitting, b, and the number of hours she spends tutoring, t, in a week, and represent the sum as less than or equal to 12:

b + t < 12

Solving system of equations

Answers

im assuming you meant 2x + y = 6 instead of 2x = y = 6

answer:
x = 14/3
y = -10/3

step by step explanation:
2x + y = 6
x + 2y = -2
solve for y in the first equation
y = 6 - 2x
plug y into the second equation
x + 2(6 - 2x) = -2
-3x + 12 = -2
-3x = -14
x = 14/3
plug into the y equation
y = 6 - 2(14/3)
y = -10/3

Write the Linear Equation in Point-Slope Form for a line that has a slope of
-10 and passes through the point (8,2). *

Answers

Answer:

y = -10x + 82

Step-by-step explanation:

Plug in the slope and point into y = mx + b to solve for b:

y = mx + b

2 = -10(8) + b

2 = -80 + b

82 = b

Then, plug b and the slope into y = mx + b

y = -10x + 82 is the equation in point slope form.

(2,-9) because it turns 180 degrees meaning your going to rotate it twice.

It should be (2, -9). When rotating 180° you always make the x and y the opposite, so you take the opposite of -2 and the opposite of 9 to get (-2, 9). Hope this helps!

A. 33cm
B. 0.002
C. 0.03
D. 7500 cm

Answers

Answer:

Option C - 0.03 cm

Step-by-step explanation:

The model has a length of 15 cm.

Now, we are told that the scale is 1:500. This means that 1 unit is represents 500 cm on the model.

Since the length on the model is 15 cm which is 15 units, then the true length would be;

15 × 1/500 = 0.03 cm

Therefore, the true length is 0.03 cm.

Option C is correct

Step-by-step explanation:

m = 46° (vertical angles)

j = 92° (vertical angles)

j + k + 46° = 180° (staright line angles)

92° + k + 46° = 180°

k = 180° - 138°

k = 42°
