Answer:

$0.25

Step-by-step explanation:

First, find how much the stickers and candy cost in total:

3.25 + 6.50

= 9.75

Subtract this from 10 to find how much change she got back:

10 - 9.75

= 0.25

So, she got back $0.25 in change

Answer:

The volume of the prism is 243 ft^3.

Step-by-step explanation:

The equation you have to use is A=Bh

Answer: 121.5 ft3

Step-by-step explanation:

Use this formula for volume of triangulsr prism:

1/2 • length • width • height

That will be 1/2 • 4.5 • 9 x 6 = 121.5

Unit of measurement is ft3 (also same as cubic feet)

Answer:

25 min

Step-by-step explanation:

165 min = 2 hr 45 min

2 hr 45 min - 1 hr 45 min = 1 hr

1 hr - 35 min = 25 min

Answer:

The appropriate solution is Option D (22 m/sec).

Step-by-step explanation:

The given equation is:

[tex]s(t)= -(t-15)^2 + 225[/tex]

Now,  

The instantaneous velocity at t = 4 will be:

= [tex][-2(t-15)(1)+0][/tex]

= [tex]-2(4-15)[/tex]

= [tex]-2\times (-11)[/tex]

= [tex]22 \ m/sec[/tex]

Thus, the above is the correct option.

(a) Both conditions are satisfied with x = (1, 0) for [tex]\mathbb R^2[/tex] and x = (1, 0, 0) for [tex]\mathbb R^3[/tex]:

||(1, 0)|| = √(1² + 0²) = 1

max{1, 0} = 1

||(1, 0, 0)|| = √(1² + 0² + 0²) = 1

max{1, 0, 0} = 1

(b) This is the well-known triangle inequality. Equality holds if one of x or y is the zero vector, or if x = y. For example, in [tex]\mathbb R^2[/tex], take x = (0, 0) and y = (1, 1). Then

||x + y|| = ||(0, 0) + (1, 1)|| = ||(1, 1)|| = √(1² + 1²) = √2

||x|| + ||y|| = ||(0, 0)|| + ||(1, 1)|| = √(0² + 0²) + √(1² + 1²) = √2

The left side is strictly smaller if both vectors are non-zero and not equal. For example, if x = (1, 0) and y = (0, 1), then

||x + y|| = ||(1, 0) + (0, 1)|| = ||(1, 1)|| = √(1² + 1²) = √2

||x|| + ||y|| = ||(1, 0)|| + ||(0, 1)|| = √(1² + 0²) + √(0² + 1²) = 2

and of course √2 < 2.

Similarly, in [tex]\mathbb R^3[/tex] you can use x = (0, 0, 0) and y = (1, 1, 1) for the equality, and x = (1, 0, 0) and y = (0, 1, 0) for the inequality.

(c) Recall the dot product identity,

x • y = ||x|| ||y|| cos(θ),

where θ is the angle between the vectors x and y. Both sides are scalar, so taking the norm gives

||x • y|| = ||(||x|| ||y|| cos(θ)|| = ||x|| ||y|| |cos(θ)|

Suppose x = (0, 0) and y = (1, 1). Then

||x • y|| = |(0, 0) • (1, 1)| = 0

||x|| • ||y|| = ||(0, 0)|| • ||(1, 1)|| = 0 • √2 = 0

For the inequality, recall that cos(θ) is bounded between -1 and 1, so 0 ≤ |cos(θ)| ≤ 1, with |cos(θ)| = 0 if x and y are perpendicular to one another, and |cos(θ)| = 1 if x and y are (anti-)parallel. You get everything in between for any acute angle θ. So take x = (1, 0) and y = (1, 1). Then

||x • y|| = |(1, 0) • (1, 1)| = |1| = 1

||x|| • ||y|| = ||(1, 0)|| • ||(1, 1)|| = 1 • √2 = √2

In [tex]\mathbb R^3[/tex], you can use the vectors x = (1, 0, 0) and y = (1, 1, 1).

Answer:

The answer would be 3.33.

Step-by-step explanation:

Simplifying 12x + 5 = 3x + 35

Reorder the terms: 5 + 12x = 3x + 35

Reorder the terms: 5 + 12x = 35 + 3x

Solving 5 + 12x = 35 + 3x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-3x' to each side of the equation. 5 + 12x + -3x = 35 + 3x + -3x

Combine like terms: 12x + -3x = 9x 5 + 9x = 35 + 3x + -3x

Combine like terms: 3x + -3x = 0 5 + 9x = 35 + 0 5 + 9x = 35

Add '-5' to each side of the equation. 5 + -5 + 9x = 35 + -5

Combine like terms: 5 + -5 = 0 0 + 9x = 35 + -5 9x = 35 + -5

Combine like terms: 35 + -5 = 30 9x = 30

Divide each side by '9'. x = 3.333333333

Simplifying x = 3.333333333

Answer:

85

Step-by-step explanation:

A z-score of 1.25 means that the actual exam score is 1.25 standard deviations above the mean, and therefore the exam score we are looking for is: mean + 1.25 * SD = 75 + 1.25 * 8 = 85

Answer:

3x - 7y = 14

Step-by-step explanation:

standard form is: ax + by = c

first, add 2 to each side of the equation to get:

2 + y = 3/7x

now multiply each term by 7 to eliminate fraction:

14 + 7y = 3x

now subtract 7y from each side to get:

3x - 7y = 14

Answer:

314 m²

Step-by-step explanation:

the formula for the surface area of a sphere (As) is

As = 4×pi×r²

the radius r (half of the diameter) is clearly indicated as 5m.

so, As = 4×3.14×5² = 4×3.14×25

I don't even need a calculator for this, as 4×25 = 100

so, As = 100×3.14 = 314

(you know, when multiplying by 10, the decimal point moves right one position. multiply by 100 it moves 2 positions, and so on).

The diagonals of a rectangle are equal and bisect each other.

NQ= 2×5 =10

Using Pythagoras theoram,

PQ²+NP²=NQ²

4²+ NP²= 10²

NP²= 100-16

NP²= 84

NP =√84

Explanation:

You're dividing in the wrong order.

You divide the price over the number of items to get the unit price.

So you should say 95/16 = 5.9375 which then rounds to 5.9

----------------

Why does it work? Well consider the fact we can set up this ratio

16 ounces : 95 cents

we then divide both sides by 16 to turn that "16 ounces" into "1 ounce"

Doing so leads us to

1 ounce : 5.9375 cents

Answer:

0° < x < 83.76°

Step-by-step explanation:

Assuming a pyramid with a square base, and the height of the pyramid varies from almost zero to almost infinity.

The largest value for the angle x+2 is when the height of the pyramid is almost zero.

Then the face is an isosceles triangle with base 13 and height 14.

The angle opposite the base is then

x+2  = 2*atan(6.5/7) = 2* 42.879 = 85.76°

when the height is almost infinite, the angle is almost zero.

Therefore the range of the value of x

0° < x < 83.76°

Answer:

-2

Step-by-step explanation:

f(x) = 3x^2 + 5x - 14

substitute -3 inplace of x

f(-3) = 3*(-3)^2 + 5*(-3) - 14

=3*9 - 15 - 14

=27 - 15 - 14

= -2

Answer:

(x, y) = (-1, 1)

Step-by-step explanation:

8x + y = −7

8x = -8

divide bot sides by 8

x = -1

(x, y) = (-1, 1)

Answer:

[tex]d = 6[/tex]

Step-by-step explanation:

Given

[tex]S_n = 3n^2 + 5n[/tex]

Required

Find d

First, find the sum of the first 1 term

[tex]S_1 = 3 * 1^2 + 5 * 1[/tex]

[tex]S_1 = 8[/tex]

The sum of the first 2 terms

[tex]S_2 = 3 * 2^2 + 5 * 2[/tex]

[tex]S_2 = 22[/tex]

Calculate the first term (a)

[tex]a = S_1[/tex]

[tex]a = 8[/tex]

Calculate the second term (T2)

[tex]T_2 = S_2 - S_1[/tex]

[tex]T_2 = 22 - 8[/tex]

[tex]T_2 = 14[/tex]

The common difference is:

[tex]d = T_2 - a[/tex]

[tex]d = 14 - 8[/tex]

[tex]d = 6[/tex]
