Answer:

2.5 overtime hours

Step-by-step explanation:

90$+195$=285

390-285=105$

105/42=2.5 overtime hours

Answer:

h=2.5 hours

Step-by-step explanation:

take the 30x3=90 then 195-90= 105 finally, divide 105 and 42 to get 2.5 hours!

30x3

195-90

105/2.5

Answer:

14.13

Step-by-step explanation:

Area = pi * r * r

d/2 = 2... 6/2 = 3

Area = pi *3^2

3.14*9 = 28.26

The semicircle is exactly half so you divide by 2

28.26 / 2 = 14.13

Answer:

14.13

Step-by-step explanation:

Formula for area of a semicircle: 3.14*r*r/2

6/2 = 3

3*3=9

3.14*9 = 28.26

28.26/2 = 14.13

Answer:

X=115°

Step-by-step explanation:

If you extend the line on the left up to the top, it forms a triangle.  The three interior angles of that triangle are 50, 180-x, and 180-x.  

50+180-x+180-x=180

410-2x=180

410-180=2x

230=2x

x=115°

Another way to look at it: Since two of the angles in the triangle are the same, they must total 130.  (180-50=130)

130 ÷2 equals 65.  If those angles are 65, x=180-65=115°

Answer:

C. y = 2x + 8

Step-by-step explanation:

✔️First, find the slope of the line that goes through points (-2, 4) and (6, 20):

Slope (m) = ∆y/∆x = (20 - 4) / (6 - (-2))

Slope (m) = 16/8

m = 2

✔️Find the y-intercept (b):

To do this, substitute (x, y) = (6, 20) and m = 2 into y = mx + b

Thus:

20 = 2(6) + b

20 = 12 + b

20 - 12 = b

8 = b

b = 8

✔️Write the equation by substituting m = 2 and b = 8 into y = mx + b

Thus:

y = 2x + 8

Answer:

Step-by-step explanation:

solution is the point of intersection, (0,1)

Solution of the system of equations is, (0, 1)

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

A system of equations is shown on the graph.

Now, We have seen that;

Both the graph intersect at a point (0, 1), which is solution of the graph.

Hence, Solution of the system of equations is, (0, 1)

Thus, Solution of the system of equations is, (0, 1)

Answer:

  f(x), h(x), g(x)

Step-by-step explanation:

For a quadratic in standard form, ...

  ax² +bx +c

the axis of symmetry is ...

  x = -b/(2a)

For the various functions, the axes of symmetry are ...

  f(x): x = 0/(2·3) = 0

  g(x): x = -(-4)/(2·1) = 2

  h(x): x = (-4)/(2(-2)) = 1

From least to greatest axis of symmetry the functions are ...

  f(x), h(x), g(x)

he doesn't have any black socks

Answer:

Step-by-step explanation:

Of the ten socks,

10/11 chance of wearing white socks

1/11 chance of wearing red socks

0/11 chance of wearing any OTHER color

Black socks fall into the final row, which is the OTHER color, meaning there is no chance he can wear black socks.

Answer:

0.00002 = 0.002% probability of actually having the disease

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which

P(B|A) is the probability of event B happening, given that A happened.

[tex]P(A \cap B)[/tex] is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Positive test

Event B: Having the disease

Probability of having a positive test:

0.05 of 1 - 0.000001(false positive)

0.99 of 0.000001 positive. So

[tex]P(A) = 0.05*(1 - 0.000001) + 0.99*0.000001 = 0.05000094[/tex]

Probability of a positive test and having the disease:

0.99 of 0.000001. So

[tex]P(A \cap B) = 0.99*0.000001 = 9.9 \times 10^{-7}[/tex]

What is the probability of actually having the disease

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{9.9 \times 10^{-7}}{0.05000094} = 0.00002[/tex]

0.00002 = 0.002% probability of actually having the disease

Answer:

Jon is 11 years old

Step-by-step explanation:

We write the following equations describing the sentences of the problem, using the letter M to represent Jon's mom's current age, and j to represent his current age.

First sentence: "Six years ago Jon was one-sixth the age of his mother."

translates into:

J - 6 = (M - 6) / 6

Second sentence: "in four years time his age doubled and increased

by 10 will match his mother's age."

2 * (J + 4) + 10 = M + 4   which removing parentheses gives: 2 J + 18 = M + 4

We solve for "M" in the first equation

6 (J - 6) = M - 6

6 J - 36 = M - 6

M = 6 J - 30

and now use this result to substitute for M in the second equation

2 J + 18 = (6 J - 30) + 4

and work on solving for J

2 J + 18 = 6 J - 30 + 4

18 + 26 = 6 J - 2 J

44 = 4 J

J = 44 / 4

J = 11

I believe the answer is C.

Step-by-step explanation:

Answer:

Step-by-step explanation:

It would be B. since both triangles are right triangles. They also are on the same line. So neither of them are at a different angle.

Now to verify that this is correct, we need to eliminate some of the other answers.

Let's start with A.. Congruent means that they are the same shape and size and can be mirrored/backwards. These triangles are the same shape and mirrored but it IS NOT the same size. This means we can eliminate answer A..

Now answer C.. As originally stated, the triangles are similar because they are both right triangles, but they have the same slope since they are on the same line. The line is not changing so the slope will not change either.

And finally answer D.. Answer D. has been proven wrong from the answers B. and C., so we can eliminate it.

This means all the answers are eliminated but B.

Answer:

156 cm²

Step-by-step explanation:

Area of Triangle

= 1/2 * b * h

= 1 /2 * (17 - 9) * 12

= 6 * 8

= 48 cm²

Now

Area of parallelogram

= b * h

= 9 * 12

= 108 cm²

Total area

= (48 + 108) cm²

= 156 cm²
