Answer:

Equation 1,

[tex]x + 2y = 11[/tex]

Equation 2,

[tex]x - 2y = 11[/tex]

Take equation number 2.

[tex]x - 2y = 11 \\ x = 11 + 2y[/tex]

Substitute 'x' in Equation number 1.

[tex]x + 2y = 11 \\ 11 + 2y + 2y = 11 \\ 11 + 4y = 11 \\ 4y = 11 - 11 \\ 4y = 0 \\ y = \frac{0}{4} \\ y = 0[/tex]

y = 0.

So x,

[tex]x = 11 - 2y \\ x = 11 - 2(0) \\ x = 11 - 0 \\ x = 11[/tex]

x = 11.

Answer:

using elimination method multiply both equations by 2...then subtract equation 2 from 1

Answer:

Circumference of circle = 138.28 cm (Approx.)

Area of circle = 1,521.11 cm² (Approx.)

Step-by-step explanation:

Given:

Radius of circle = 22 cm

Find:

Circumference of circle

Area of circle

Computation:

Circumference of circle = 2πr

Circumference of circle = 2(22/7)(22)

Circumference of circle = 2(3.1428)(22)

Circumference of circle = 138.2832

Circumference of circle = 138.28 cm (Approx.)

Area of circle = πr²

Area of circle = (22/7)(22)²

Area of circle = (3.1428)(22)(22)

Area of circle = 1,521.1152

Area of circle = 1,521.11 cm² (Approx.)

Answer:

84sq. in

Step-by-step explanation:

Area of the rectangle  = length * width

Given

Length = 7in

Width = 12in

Area of the rectangle = 7in * 12in

Area of the rectangle = 84sq. in

Hence the area of the rectangle is 84sq. in

Answer:

(4x²+36) feet²

Step-by-step explanation:

Area of the pool = L × W

Take width as x and Length as 4x

4x × x = (4x²)feet² {area of pool}

Area of walkway = L × W

6 × 6 = 36feet²

Total area = 4x² + 36 feet²

Probably D,  he's measuring voltage across the wire.. and then across the light bulb,   there would be very little across the wire and a lot across the light bulb

Answer: Because the question uses the word “distinct” meaning obvious, and clear, I would select AB, AC, CB. (If it’s asking for all the possible line segments, I would select AB, AC, CB, BA, CA, BC).

Answer:

D is the correct answer.

Step-by-step explanation:

-Subtract final value by start value

-Divide by start value

-Multiply by 100

Step-by-step explanation:

Answer:

a) 0.27 = 27% probability that a randomly chosen card holder has annual income $20,000 or less.

b) 0.778 = 77.8% probability that (s)he carries a balance

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.

a) What is the probability that a randomly chosen card holder has annual income $20,000 or less?

20% of 30%(carry no balance).

30% of 70%(carry balance). So

[tex]P = 0.2*0.3 + 0.3*0.7 = 0.06 + 0.21 = 0.27[/tex]

0.27 = 27% probability that a randomly chosen card holder has annual income $20,000 or less.

b) If this card holder has an annual income that is $20,000 or less, what is the probability that (s)he carries a balance?

Conditional probability.

Event A: Annual income of $20,000 or less.

Event B: Carries a balance.

0.27 = 27% probability that a randomly chosen card holder has annual income $20,000 or less

This means that [tex]P(A) = 0.27[/tex]

Probability of a income of $20,000 or less and balance.

30% of 70%, so:

[tex]P(A \cap B) = 0.3*0.7 = 0.21[/tex]

The probability is:

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.21}{0.27} = 0.778[/tex]

0.778 = 77.8% probability that (s)he carries a balance

Answer:

A≈471.24 is the surface area of the cylinder

58m^2 is the surface area of the triangular prism

Step-by-step explanation:

Solution

A=2πrh+2πr2=2·π·5·10+2·π·52≈471.2389

Triangle area formula

area = 0.5 * b * h , where b is the length of the base of the triangle, and h is the height/altitude of the triangle.

4(2.5)+8(6)

10+48=58m^2

Answer:

y = 54

Step-by-step explanation:

Once again we are going to use the inscribed angle and intercepted arc relationship where the inscribed angle is equal to half of the measure of the intercepted arc.

Angle "y" is the inscribed angle and its intercepted arc has a measure of 108°

So y = one half of 108

[tex]\frac{108}{2} =54[/tex]

So we can conclude that y = 54
