25. Willa purchases a vase for her kitchen
that is shaped like a cube and will hold 343
cubic inches of water. What are the
dimensions (length, width and height) of the
vase?

Answers

Answer:

7,7, and 7

Step-by-step explanation:

If she vase is cubical we know that all 3 dimensions are the same. This means that x^3 = 343. So we know the answer is the cube root of 343, which is 7

The dimensions of the cubic vase are 7 by 7 by 7.

What is a cube?

A three-dimensional object with six congruent square faces is called a cube. The cube's six square faces all have the same dimensions.

Given that the volume of the cubic vessel is 343 cubic inches.

The formula for the volume of a cube of side length a is:

V =a³

Substitute V= 343:

343 = a³

Or, a = ∛343

a = 7

Hence, the dimensions of the cubic vase are 7 by 7 by 7.

2x - (3-x) > x+1 solve

Answers

Answer:

x > 2

Step-by-step explanation:

Step 1: Write inequality

2x - (3 - x) > x + 1

Step 2: Solve for x

Distribute negative: 2x - 3 + x > x + 1Combine like terms: 3x - 3 > x + 1Subtract x on both sides: 2x - 3 > 1Add 3 to both sides: 2x > 4Divide both sides by 2: x > 2

Here we see that any value x greater than 2 would work as a solution.

Find the midpoint of the segment with the following endpoints.
(6,3) and (0,9)
help please

Answers

to find the midpoint we take both x values of the ordered pairs, add them together, and divide them by two. then we do the same for the y.

x1 = 6
y1 = 3
x2 = 0
y2 = 9

add the x’s together:

x1 + x2 aka:
6 + 0 = 6
divide 6 by 2 which = 3

that’s our new x.
now we do the y’s.

y1 + y2 aka:
3 + 9 = 12
divide 12 by 2, and we get 6.

that’s our new y.

now we put the x and y together as an ordered pair and the midpoint:

Multiple-choice test with 50 questions has five possible choices for each question. There are 4 marks for each correct answer, -1 mark for each incorrect answer, and 0 marks for each unanswered question. What is the total score of a student with 35 correct answers, 10 incorrect answers and 5 unanswered

Answers

Answer:

Total score of a student = 130 marks

Step-by-step explanation:

Marks for each correct answer = [tex]4[/tex]

Marks for each incorrect answer = [tex]-1[/tex]

Marks for each unanswered question = [tex]0[/tex]

Number of correct answers = 35

Number of incorrect answers = 10

Angel H and G are both are 51 degrees, and angle I is 78 degrees.

The two angles (H and G) are equal to each other, but before we know what the angles are, we must find x.

[tex]5x + 6 = 2x + 33[/tex]

[tex]3x = 27[/tex]

[tex]x = 9[/tex]

Plug in x for one equation:

[tex]5x + 6[/tex]

[tex]5(9) + 6[/tex]

[tex] = 51[/tex]

Therefore,

[tex]m < h = 51 \:[/tex]

and

[tex]m < g = 51[/tex]

And because we know the angles within a triangle = 180, we subtract 102 from 180 to find m<I:

[tex]180 - (51 + 51) = [/tex]

[tex]180 - 102 = [/tex]

[tex] = 78[/tex]

find the nth terms of the sequence with the following first four terms as shown in the table.

________________________
n 1 2 3 4
________________________
an 5 9 13 17
_______________________ ​

Answers

Answer:

see explanation

Step-by-step explanation:

Both sequences have a common difference between consecutive terms, that is

2 - 1 = 3 - 2 = 4 - 3 = 1

This indicates the sequence is arithmetic with n th term

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 1 and d = 1 , thus

[tex]a_{n}[/tex] = 1 + n - 1 = n

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

Similarly

d = 9 - 5 = 13 - 9 = 17 - 13 = 4 and a₁ = 5 , then

[tex]a_{n}[/tex] = 5 + 4(n - 1) = 5 + 4n - 4 = 4n + 1

Answer with step-by-step explanation:

(4 x 2x) - (4 x 3) = 8x - 12

Hope this was helpful!

Answer: 8x + -12

Explanation: Let's simplify this problem using the distributive property.

The first thing we want to do is change the minus to plus a negative.

Now we can distribute or multiply this 4 times

each of the terms inside the set of parenthses.

So we get 4(2x) + 4(-3) and this simplifies to 8x + -12.

Note that if you wrote your answer as 8x - 12, it means the same thing.

For an exponential function, Its graph is a smooth curve. Option 3 is correct.

What is an exponential function?

It is defined as a function that rapidly increases and the value of the exponential function is always positive. It denotes with exponent y = aˣ, where a is a constant and a>1.

A smooth curve can be found on the graph of an exponential function, which uses exponents. In an exponential function, the rate of change is not constant. Exponential functions include the ones at y = 0.5x and y = 2x in the graph below.

Because the slopes of exponential functions are nonlinear and constantly changing, their graphs resemble curves rather than straight lines.

Hence, for an exponential function, Its graph is a smooth curve. Option 3 is correct.
