Answer:

1/8

Step-by-step explanation:

( 2^-1 / 2^0) ^3

First simplify inside the parentheses

We know that a^b / a^c = a^(b-c)

2^(-1-0) = 2^-1

( 2^-1 ) ^3

Then we know that a power to a power is

a^b^c = a^(b*c)

2^(-1  *3)

2^ -3

Then a negative exponent makes it a fraction

a^ -b = 1/a^b

1 /2^3

Answer:

Total Volume = 190 m³

Step-by-step explanation:

Volume of the entire figure = L (Area 1  + Area 2)

where L = 10 m

Area 1 (blue prism) = 4 x 3 = 12 m²

Area 2 (brown prism = 1 x 7 = 7 m²

plugin  values into the formula:

Volume of the entire figure = L (Area 1  + Area 2)

                                            = 10 (12 + 7)

                                            = 120 m³ + 70 m³

                                            = 190 m³

Answer:

[tex]\frac{1}{36}[/tex]

Step-by-step explanation:

Dice has 6 sides.

2 is one of the six.

First die landing on two is

[tex]\frac{1}{6}[/tex]

The second has to land on a five.

5 is one of the six.

Second die landing on five is

[tex]\frac{1}{6}[/tex]

[tex]\frac{1}{6}[/tex] × [tex]\frac{1}{6}[/tex]

[tex]\frac{1}{36}[/tex]

Answer:

4) Alternate angles

Step-by-step explanation:

Alternate angles are on the opposite corners of the line of the angle, and 10 and 14 are on opposite corners, so that makes them alternate angles. I hope this helped you!

Answer:  [tex]2\sqrt{2}[/tex]

=====================================

Explanation:

Let's say we replace every copy of [tex]\sqrt{2}[/tex] with x

Doing so means we have the expression 5x-3x. That simplifies to 2x.

The last thing to do is replace the x with [tex]\sqrt{2}[/tex] and that's how we end up with [tex]2\sqrt{2}[/tex] as the final answer.

----------

In short: we subtract the numbers out front, and then tack on a root 2 at the end.

As another example, [tex]19\sqrt{2}-11\sqrt{2} = (19-11)\sqrt{2} = 8\sqrt{2}[/tex]

This is basically the same as saying 19x-11x = (19-11)x = 8x where [tex]x = \sqrt{2}[/tex]

Answer:

The answer is 1/3.

Step-by-step explanation:

A coin has either heads or tails. The odds of a coin getting heads is 1/2.

There are three equal-sized sections with numbers 3, 6 and 9 on the spinner. There are two sections with numbers greater than 3, which are 6 and 9. The odds of getting a number greater than 3 is 2/3.

To find the overall probability of both incidents occurring, the two fractions are multiplied together, which is 1/2 * 2/3 = 1/3

Answer:

0.333/1/3

Step-by-step explanation:

Well, the probability of getting heads is 1/2 since there are 2 sides to a coin. There are 2 numbers on the spinner greater than three (6,9) which is 2/3.

1/2 times 2/3=0.33. The probability of getting heads and getting a number that is greater than is 0.333 or 1/3.

Answer:

The circle

Step-by-step explanation:

A polygon is a flat, two-dimensional (2D) shape with straight sides that is fully closed (all the sides are joined up). The sides must be straight. Polygons may have any number of sides. A shape with curved sides is not a polygon.

Answer:

A circle

Step-by-step explanation:

A polygon is a closed figure on a plane, a circle is curved, it cannot be formed from line segments.

Answer:

80 degrees

Step-by-step explanation:

angle 1 is equal to 100 because of the law of exterior angles. And since andgle 1 and 2 make 180 degrees we can subtract 80 from 100 and we get the measure of angle 2. Angle 2 and 4 are the same becasue of the law of adjacent angles.

Answer:

the awnser is c. p-250 + p

Answer:

LM = 8 cm

Step-by-step explanation:

LM = KN = x + 7

NM = KL = x + 7 + NQ = x + 7 + 2 = x + 9

KN×NM = 80

(x+7)(x+9) = 80

x² + 7x + 9x + 63 = 80

x² + 16x + 63 = 80

x² + 16x - 17 = 0

solution of a quadratic equation

x = (-b ± sqrt(b² - 4ac))/(2a)

a=1

b=16

c=-17

(-16 ± sqrt(256 + 4×17))/2 = (-16 ± sqrt(256+68))/2 =

= (-16 ± sqrt(324))/2 = (-16 ± 18)/2

x1 = (-16 + 18)/2 = 2/2 = 1

x2 = (-16 - 18)/2 = -34/2 = -17

x2 as negative value is no valid solution for a side length.

so, only x1 remand as solution.

=> x=1, LM = KN = 1+7 = 8, NM = KL = 1+9 = 10

Answer:

-1/13

Step-by-step explanation:

The slope of a line is calculated as rise/run.

The rise is the difference in y-values, and the run is the difference in x values

slope= y₂ - y₁/x₂ - x₁

let (26 , 7) be (x , y) and (-39 , 12) be (x₂, y₂)

slope= (12 - 7)/ (-39 -26)

        = 5/-65

reduce the fraction to get -1/13

Answer:

$30

Step-by-step explanation:

first, take 25% of 120

then, turn the percent to a decimal (move the percent to the left twice, equals 0.25)

0.25 times 120

this equals 0.3

then turn the decimal to a whole number by moving the decimal to the right two times

0.3= 30

$30

Answer:

0.1749

Step-by-step explanation:

We are to find the probability that none of the house-holds tuned to 50 minutes.

P(tune to 50 minutes) = 0.16

p = 0.16

q = 1 - 0.16

q = 0.84

number of households (n) = 10

x = number of households that tuned at 50 minutes

since none of the household tuned, then:

x = 0

Using the binomial expression:

[tex]P(x=x) ^nC_xp^xq^{(n-x)}[/tex]

[tex]P(x=0) = ^{10}C_0 \ (0.16)^0 \ (0.84)^{(10-0)}[/tex]

[tex]P(x=0) = \dfrac{10!}{(10-0)!0!} \ (0.16)^0 \ (0.84)^{(10)}[/tex]

[tex]P(x=0) = 1 \times \ 1 \times 0.1749[/tex]

P(x =0) = 0.1749

Answer:

x = 0

y = -4

negative 4 cuz the line goes down, meaning it's negative

Answer: The value of x can be either 5 or 10.

Step-by-step explanation:

We are given:

Total profit, P = $5600

The given equation follows:

⇒ P = 600 + 1500x - 100x²

Putting value of P in above equation, we get:

⇒ -100x² + 1500x + 600 = 5600

⇒ -100x² + 1500x - 5000 = 0

⇒ 100x² - 1500x + 5000 = 0

Solving this equation by middle term split, we get:

⇒ 100(x² - 15x + 50) = 0

⇒ (x² - 10x - 5x + 50) = 0

⇒ x(x - 10) - 5(x -10) = 0

⇒ (x - 10)(x - 5) = 0

⇒ x = 10, 5

Hence, the value of x can be either 5 or 10.

Answer: B

Step-by-step explanation: I just took the quiz

The measurement of angle 7 is 123°.

The corresponding angles are angles that have the same relative position or measurement in two similar figures. They are formed when two lines, parallel or not, are intersected by a transversal. They are located on the same side of the transversal. Corresponding angles formed by parallel lines and a transversal are congruent.

Given is scene of two parallel line intersected by a transversal,

∠3 = 123°, We need to find the value of ∠7,

We see that, the angles, ∠3 and ∠7 are corresponding angles,

Therefore,

∠3 = ∠7 by the definition of corresponding angles between parallel lines,

Therefore, ∠7 = 123°.

Hence, the measurement of angle 7 is 123°.

2. Ashley is not correct, since 441902 + 312684 is 754,586; not 753,586. She made a mistake on the thousands place, which she probably added one extra on accident.

Step-by-step explanation:

Oki, subtract for question one:

441902 - 312684 = 129218

Add for two:

441902 + 312684 = 754586
