I need some help this math problem

I don't know why doesn't have answers, but I know the answer 7/20.

Answer:

B. X

Step-by-step explanation:

Each X value can only have one Y value.

Answer:

2 hours

Step-by-step explanation:

variable x = hours

fix it fast: 25 + 50x

do it right: 35 + 45x

25 + 50x = 35 + 45x

subtract 45x from both sides

subtract 25 from both sides

(this action cancels out 45x on the right side and 25 on the left side so you can combine like terms)

50x - 45x = 35 - 25

5x = 10

divide by 5 on both sides

x = 2

Answer:

[tex]\dfrac{3}{5}[/tex]

Step-by-step explanation:

Given that:

Total Number of fourth downs = 10

Number of fourth downs converted to first downs = 6

Formula for probability of an event E can be observed as:

[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}[/tex]

Here, Let E be the event of getting a fourth down converted to first down.

So, Number of favorable cases = 6

Total Number of cases = 10

Therefore, the required probability is:

[tex]P(E) = \dfrac{6}{10} = \dfrac{3}{5}[/tex]

Answer:

C

Step-by-step explanation:

I used google to search up exponential function and it showed a lot of graphs and they're all curved.

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

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.

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.

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.

Answer:

The length of C'D' = 2.8

This is because, ABCD  is rotated on the point R 55 degrees

So, now, if you turn back the rotation, you will get, that CD = C'D'

Now, CD = 2.8 , So, C'D' = 2.8

Given parameters:

Total length of curtains bought = 20m

She used 8m for the living room

She used 7m for the dining room

unknown:

Quantity used for the kitchen = ?

Solution:

Quantity used for the kitchen = Total length - (living room + dining room)

Input the parameters given solve;

   Quantity used for the kitchen = 20 - (8 + 7) = 5m

The length of curtain used for the kitchen is 5m

Answer:

x > 2

Step-by-step explanation:

Step 1: Write inequality

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

Step 2: Solve for x

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

Answer:

6)z=92 y=88 x=92

7)I think all are 90

8) 62

9) 73

10) 87

Step-by-step explanation:

6)y is congruent to 88 vertical angles

and y+x=180, 88+x=180, x=92

x is congruent to z vertical angles so both 92

7) y is congruent with 90 and all the other side when subtracted by 180 equal 90

8)180-118=62

9) 90-17=73

10) 72+21=93

180-93=87

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

Number of unanswered answers = 5

So,

Total score of a student [tex]=35(4)+10(-1)+5(0)=140-10+0=130[/tex] marks

Answer:

35 correct: 35x4= 140 marks

10 incorrect: 10x -1= -10 marks

5 unanswered: 5x0= 0 marks

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.
