Answer:

362

Step-by-step explanation:

Let u = the units digit

2(u + 1) = the tens digit

u + 1 = the hundreds digit

u + 2(u + 1) + u + 1 = 11

u + 2u + 2 + u + 1 = 11

4u + 3 = 11

4u = 8

u = 2 = ones digit

u + 1 = 3 = hundreds digit

2(u + 1) = 2(3) = 6

The number is 362

Please help!!!!!!solve
fgiga [73]
I’m a bit confused confused, but the answer may be -2x^3 + 2x^2 - 2x +2

Work:

To solve this, take the equation for q and the equation for r, and multiply them together.

Use the distributive property to multiply them.

I’m not sure if this is right or not, so pls don’t get mad if it isn’t.

Thank you! :)

A cube has a volume of 343 cubic cm. What is the area of the base
Amanda [17]

Answer:

49 cm²

Step-by-step explanation:

The volume (V) of a cube is calculated as

V = s³ ← s is the length of the side, thus

s³ = 343 ( take the cube root of both sides )

s = \sqrt[3]{343} = 7, thus

area of base = s² = 7² = 49 cm²

F(x) = -2x + 9, find x if f(x) = 23
JulijaS [17]

Answer:

x = -7

Step-by-step explanation:

f(x) = -2x + 9

f(x) = 23

therefore, f(x) =

-2x + 9 = 23

     -2x = 23 - 9

     -2x = 14

       -x = 14 ÷ 2

       -x = 7

        x = -7

A​ student's course grade is based on one midterm that counts as ​% of his final​ grade, one class project that counts as ​% of
Andrei [34K]

Answer:

The overall score is 75.6

Letter grade is C

Step-by-step explanation:

The question has missing details (See comment section for complete question).

From the complete question, we have:

<u>Proportion:</u>

Midterm = 15\%

Project = 25\%

Assignment = 40\%

Exam = 20\%

Scores

Midterm = 66

Project = 90

Assignment = 75

Exam = 66

Solving (a): The overall score

To do this, we simply calculate the mean of the given data.

The mean is calculated by multiplying each proportion by the scores..

So, we have:

Overall = 15\% * 66 + 25\% * 90 + 40\% * 75 + 20\% * 66

Overall = 9.9 + 22.5 + 30 + 13.2

Overall = 75.6

Solving (b): The letter grade

From the question, we have:

A: Mean \ge 90

B: 80 \le Mean < 90

C: 70 \le Mean < 80

The overall score falls in the following category:

C: 70 \le Mean < 80

Because:

70 \le 75.6 < 80

<em>Hence, the letter grade is C</em>
