x=−225
Decimal Form:
x=−4.4
Mixed Number Form:
x=−4 2/5
Step-by-step explanation:
Answer:
x = 6
Step-by-step explanation:
1/4 (x-2) + 5 = x
1/4 (x-2) = x - 5
x - 2 = 4(x-5)
x-2 = 4*x + 4*-5
x-2 = 4x - 20
x - 4x = 2 - 20
-3x = -18
x = -18/-3
x = 6

If BC = x − 2, CD = 19, and BD = 3x − 11, what is BD? Simplify your answer and write it as a proper fraction, mixed number, or integer. Could you please type the answer in a step by step.
Answers
Answer:
UV = 15
BD= 31
Step-by-step explanation:
Since, U is the midpoint of TV.
Therefore,
TU = UV
x + 10 = 3x
x - 3x = - 10
-2x = - 10
x = - 10/-2
x = 5
UV = 3x = 3*5
UV = 15
BD = BC + CD
3x - 11 = x - 2 + 19
3x - 11 = x + 17
3x - x = 11 + 17
2x = 28
x = 28/2
x = 14
BD = 3x - 11 = 3*14-11 = 42 - 11
BD= 31

In Seattle, WA, it is said to rain 66% of the time. Since there are 365 days in a year, approximately how many days is it expected To rain?
Answers
xdays is 66%
66x365 =24090
24090/100= 240,9
it’s expected to rain approximately 241 days
In a year with 365 days, it should rain for about 240 of those days for the given condition.
What is the percentage?It is the ratio of two integers expressed as a decimal fraction of a whole number. It is a statistic for contrasting two sets of data, and the % sign is used to describe it as a percentage. Percentages are often and creatively used. For instance, a lot of data is published as percentages in the media, including bank interest rates, retail discounts, and inflation rates.
It is supposed to rain 66% of the time in Seattle, Washington. Considering that there are 365 days in a year,
Suppose the number of days is it expected to rain obtained be x,
x=66% of 365
x=66/100 × 365
x=240,9 ≈ 240
Thus, it should rain for about 240 days.

1) Identify the volume of a rectangular pyramid with length 16 m, width 12 m, and height 17 m. 2) Identify the volume of a regular hexagonal pyramid with base edge length 8 in. and height 10 in. rounded to the nearest tenth. PLEASE HELP
Answers
Answer:
First problem: 1088 [tex]m^{3}[/tex]
Second problem: 554.3 [tex]m^{3}[/tex]
Step-by-step explanation: Please see the images below!
The volumes of both the pyramids are 1088 m³ and 554.3 in³.
What is volume?The volume of a shape or solid is the space occupied by it, which also includes its height or depth.
a) To find the volume of the pyramid, first calculate the area of the base.
B = lw
Substitute 16 for l and 12 for w.
B = 16 ⋅ 12
Simplify.
B = 192 m²
To find the volume of the pyramid, use the formula for the volume of a pyramid.
V = 1/3 Bh
Substitute 192 for B and 17 for h.
V = 1/3 ⋅ 192 ⋅ 17
Simplify.
V = 1088 m³
Therefore, the volume of the rectangular pyramid is 1088 m³.
b) Similarly for the volume of a regular hexagonal pyramid with base edge length 8 in. and height 10 in.
Base area = 96√3 in²
Volume = 1/3 × 96√3 in² × 10 in
= 554.3 in³
Hence, the volumes of both the pyramids are 1088 m³ and 554.3 in³.

Choose the correct answer below
O A. The student did not put the polynomial in ascending order of the degrees of the terms before naming it by the first term. It is a linear trinomial.
O B. The student did not combine like terms before naming the polynomial. It is a degree-8 polynomial.
O C. The student did not put the polynomial in standard form before naming it by the first term. It is a fourth-degree trinomial.
OD. The student did not put the polynomial in standard form before naming it by the first term. It is a quadratic trinomial.
Answers
Answer:
C. The student did not put the polynomial in standard form before naming it by the first term. It is a fourth-degree trinomial.
Step-by-step explanation:
A trinomial is a polynomial with three variables. The polynomial -2x³ + 5x⁴ - 3x has three variables hence it is a trinomial.
The degree of a polynomial is the highest degree of a variable in a polynomial equation.
The polynomial -2x³ + 5x⁴ - 3x can be arranged as The polynomial 5x⁴ - 2x³ - 3x, hence the variable with the highest degree is 5x⁴ which has a degree of 4.
Therefore The polynomial -2x³ + 5x⁴ - 3x has a degree of 4
This means the polynomial -2x³ + 5x⁴ - 3x is a trinomial with a degree of 4

Savannah's balance in her checking account was –$638.57. She deposited two checks, each in the amount of $298.40. What is Savannah’s new checking account balance after the deposits?
Answers
Answer:
$-41.77
Step-by-step explanation:
$298.40 multiplied by 2 is $596.8, since Savannah added 2 deposits.
Now we add that to the current balance, -$638.57, to get an answer of $-41.77
Answer:
-41.77
Step-by-step explanation:
Multiply $298.40 by 2 OR add $298.40 + $298.40
either gives you $596.80
Savannah deposited $596.80
You add that to -$638.57

A carton has a length of fraction 2 and 1 over 6 feet, width of fraction 1 and 1 over 5 feet, and height of fraction 2 and 1 over 2 feet. What is the volume of the carton?
Answers
Answer:
6 1/2 cubic feet
Step-by-step explanation:
A carton has a length of 2 1/6 feet
The width is 1 1/5 feet
The height is 2 1/2 feet
Therefore the volume of the carton can be calculated as follows
= length × width × height
= 2 1/6 × 1 1/5 × 2 1/2
= 13/6 × 6/5 × 5/2
= 390/60
= 13/2
= 6 1/2 cubic feet
Hence the volume of the carton is 6 1/2 cubic feet
