1. The quarter coin is worth 1/4 of a dollar. How many quarters can be exchanged for 8 one-dollar bills

Answer:

48

Step-by-step explanation:

Answer:

X = 70, y = 21

Step-by-step explanation:

53 + 6y + 1 = 6y + 54

6y + 54 = 180

180 - 54 = 126

6y = 126

126 ÷ 6 = 21

Y = 21

21 × 6 + 1 = 127

127 = 2x - 13

127 + 13 = 140

140 ÷ 2 = 70

X = 70

Opposite angles are congruent and consecutive angles are supplementary.

Hope that helped and have a great day!

Answer:

[tex]Velocity = 70mph[/tex]

Step-by-step explanation:

Given

[tex]Train = 50mph[/tex]

[tex]Ball = 20mph[/tex]

Required

How fast is the ball seem to be moving?

This question illustrates relative velocity;

Since the ball and the train moves in the same direction, the required velocity relative to the person standing behind is:

[tex]Velocity = Train + Ball[/tex]

i.e. we add both velocities

[tex]Velocity = 50mph + 20mph[/tex]

[tex]Velocity = 70mph[/tex]

Step-by-step explanation:

The volume of the cube with side length a = 1 unit is given by V = 1 unit³ and it is a unit cube

The formula of volume of the cube is given by:

Volume of Cube = a x a x a

Volume of Cube = a³

where a is the length of its sides or edges

Given data ,

Let the volume of the cube be represented as V

Now , the value of V is

Let the side length of the cube be a

where the value of a = 1 unit

And , Volume of Cube = a³

On simplifying , we get

The volume of the cube = ( 1 unit )³

The volume of the cube V = 1 unit³

Hence , the volume of the unit cube is 1 cubic unit

Answer:

Description

Step-by-step explanation:

1. Factor 2x^2+11x+12 -> (2x+3)(x+4)

x=-4, -3/2

Both numbers are rational numbers as both can be expressed in the form in a quotient with integer values.

2. If discriminant is negative, then solutions are imaginary, meaning that the discriminant is less than 0, so you can set up this equation.

11^2 - 4(a)(12) < 0

121 - 48a < 0

a>121/48

The closest integer to 121/48 (~2.52) such that it satisfies the above conditions is 3, so the lowest value for a is 3.

Change the wording a bit, and type in your answer.

Answer:

1) (1/3)log_7(10); 3) log_8(u) - log_8(v); 5) 3ln(x)

Step-by-step explanation:

1)

log_7(^3sqrt(10))

log_7(10^1/3)

log_a(x^b) = b * log_a(x); when x >= 0.

(1/3)log_7(10)

About 0.39443...

3)

log_8(u/v)

log_c(a/b) = log_c(a) - log_c(b)

log_8(u) - log_8(v)

5)

ln(x^3)

log_a(x^b) = b * log_a(x); when x >= 0.

3ln(x)

Step-by-step explanation:

You don do the figuring out want number is in each exponent you simply add because you have the same base and if its multiplication you actually do addition in which multiplication is repeated addition. same for division but subtraction instead because you are lowing the number :)

Answer:

  $1,322.05

Step-by-step explanation:

The compound interest formula is appropriate.

  A = P(1 +r/n)^(nt) . . . principal P earning annual rate r for t years, compounded n times per year

You have P=1000, r=.07, n=12, t=4, so the balance is ...

  A = $1000(1+.07/12)^(12·4) ≈ $1000(1.322054)

  A = $1,322.05

Jennifer's ending balance is $1,322.05.

Answer:

distance = 10.6

Step-by-step explanation:

A's coords are (5, 6)

D's coords are (-2, -2)

So the total horizontal distance between A and D is:

5 + 2 = 7

...and the total vertical distance is:

6 + 2 = 8

Now use Pythagorean Theorem:

7^2 + 8^2 = distance^2

distance^2 = 49 + 64 = 113

distance = squareroot of 113

distance = 10.6

Answer:

y < 14/3

Step-by-step explanation:

You can immediately negate the negative from both sides by canceling the -1.

Divide both sides by 3, when you divide a < or > by anything you have to switch the sign it faces. So in this case

-3y > -14

=> 3y < 14

y < 14/3

Answer:

0.60

Step-by-step explanation:

Using the SOH CAH TOA trigonometry identity

According to the given data

∠D=90°, DC = 3, BD = 4, and CB = 5

DC is the opposite (since we are considering m<B)

BC is the hypotenuse

Tan theta = opposite/adjacent

Tan<B = DC/BC

Substitute

Tan<B = 3/5

Hence the value of the tangent of ∠B to the nearest hundredth is 0.60

Answer:

5

Step-by-step explanation:

Answer:

Step-by-step explanation:

Perimeter of the deck = (d + 5) + (d + 5) + (d + 5) + (d + 5)

1). By grouping method,

    Perimeter = (d + d + d + d) + (5 + 5 + 5 + 5)

2). Perimeter = Number of sides × Length of a side

                       = 4(d + 5)

3). Expression from problem 1,

    Perimeter = (d + d + d + d) + (5 + 5 + 5 + 5)

                      = 4d + 20

                      = 4(d + 5)

    Expression from problem 2,

    Perimeter = 4(d + 5)

    Bot the expressions are same.
