What is 7 8/9 written as a decimal

Jennie rides her bike 12 miles per hour on a trail in the park. The trail is 18 miles long. The function, f, can be used to dete

defon

Answer:

domain: [0, 1.5]
range: [0, 18]

Step-by-step explanation:

Jennie will complete her ride after 1.5 hours, so the function has no utility except for time values between 0 and 1.5 hours.

The domain is the interval [0, 1.5] (hours).

__

The range of the function is the set of possible distances along the trail, so will be values between (and including) 0 and 18 miles.

The range is the interval [0, 18] (miles).

What is 265 times 14.? Explain what you did.

AysviL [449]

Answer:

3710

Step-by-step explanation:

265 * 14

multiply 4 by 5, then 4 by 6, then 4 by 2 which would look like this 860

then you multiply 1 by 5, then 1 by 6, then 1 by 2 which should loo like 2650

it looks like that because for every digit you multiply by except the first you add a zero in front of it. then you add those two up which adds up to 3710 you're welcome. :}

Answer: Surface area = 392 in²

Step-by-step explanation:

It is divided into different sections as shown in the attached photo to aid explanation.

Looking at the attached photo

Area of A = 6 × 6 = 36 in²

Area of B = 4 × 10 = 40 in²

Area of the face containing A and B = 36 + 40 = 76 in²

Since the face is the same on the opposite end,

Area of the opposite end of AB = 76 in²

Area o C = 6 × 4 = 24 in²

Area of D = 6 × 6 = 36 in²

Area of E = 6 × 6 = 36 in²

Area of F = 6 × 4 = 24 in²

Area of base G = 10 × 6 = 60 in²

Area of back H = 6 × 10 = 60 in²

The surface area is the sum of all the faces of the given solid.

Therefore,

Surface area = 76 + 76 + 24 + 36 + 36 + 24 + 60 + 60 = 392 square inches

The reflexive property of angle congruence is represented by which of the following? Question 2 options: A) If ∠A ≅ ∠B then ∠B ≅

Nutka1998 [239]

Answer:

B) ∠A ≅ ∠A

Step-by-step explanation:

the reflexive property of congruence states that an angle, line segment, or shape is always congruent to itself.

so if an angle ∠A is an angle, then.∠A≅∠A.

the axis of symmetry of a quadratic equation is x = –3. if one of the zeroes of the equation is 4, what is the other zero?

FinnZ [79.3K]

ANSWER

The other zero is

$x = - 10$

EXPLANATION

The axis of symmetry serves as the midpoint of the two zeroes.

We were given that the axis of symmetry of the quadratic equation is
$x = - 3$

We were also given that, one of the zeroes of the quadratic equation is
$x = 4$

Let the other zero of the quadratic equation be
$x = p$

,then, we apply the midpoint formula to find the value of
$p$

Since it is the x-values of the intercepts that gives the solution, we use only the x-value part of the midpoint formula which is given by,

$\frac{x_1 + x_2}{2} = axis \: of \: symmetry$

We substitute to obtain,

$\frac{p + 4}{2} = - 3$

We multiply through by 2 to get,

$p + 4 = - 6$

This implies that,

$p = - 6 - 4$

$p = - 10$
