Answer:

x<-3

Step-by-step explanation

2x+5<x-1/4

in x-1/4 you should remove 4 so you should multiply 4 from both side

8x+20<x-1

subtract x from both side

8x-x<-1-20

7x<-21

divided by 7 from both side

x<-3 answer is x<-3

Step-by-step explanation:

a) 3x + 5y = 8

4x - 3y = 1

• using the elimination method:

3x + 5y = 8 (×4)

4x -3y = 1 (×3)

12x + 20y = 32

12x -9y = 3

subract 12x from both equation:

20y - - 9y= 32 -3

20y +9y = 29

29y= 29

y= 29/29

y= 1

- substituting y= 1 in :

4x - 3y= 1

4x - 3(1) = 1

4x -3 = 1

4x = 1 + 3

x = 4/4

x= 1

b) 6p+ 4q = 20

5p - 2q = 6

• using the elimination method:

6p + 4q = 20

5p - 2q = 6 (×2)

6p + 4q = 20

10p - 4q = 12

add 4q + -4q to eliminate q.

6p+ 10p = 20+12

16p = 32

p = 32/ 16

p = 2

- subtituting p = 2 in :

5p - 2q = 6

5(2) -2q =6

10 -2q = 6

-2q = 6 - 10

q = -4 / -2

q = 2

Answer:

Hi, 30 is 10 times as=30×10=300

Step-by-step explanation:

If you multiple with 30×10 we get as product is 300

Let ,

130° + y = 180° — ( i )

x + 107° + y = 180° — ( ii )

now ( i )

130° + y = 180°

y = 180° - 130°

y = 50°

now substituting value of y in equation ( i )

[tex]x + 107 + y = 180 \\ x + 107 + 50 = 180 \\ x + 157 = 180 \\ x = 180 - 157 \\ [/tex]

Answer:

No h-intercept/zero

Step-by-step explanation:

1- Substitute the s (h) = 0

2- Determine the defined range

3- the statement is false for any value of h

4- There is no h-intercept/zero

All the real numbers are the domain of the function. Then the range of the function will be [16π, ∞).

A function is an assertion, concept, or principle that establishes an association between two variables. Functions may be found throughout mathematics and are essential for the development of significant links.

The domain means all the possible values of x and the range means all the possible values of y.

The equation that represents the surface area of the paper cup is given below.

S(h) = 4π√(16 + h²)

Where h is the height of the cup.

The graph of the equation is drawn below. Then all the real numbers are the domain of the function.

And the lowest point of the function will be given as,

S(0) = 4π√(16 + 0²)

S(0) = 4π√16

S(0) = 16π

Then the range of the function will be [16π, ∞).

Answer:

36

Step-by-step explanation:

There are several ways to find area of triangle from vertex coordinates, the easiest is: (x₁*(y₂-y₃) + x₂*(y₃-y₁) + x₃*(y₁-y₂)) / 2

Area = ((-1)*(-6 - -6) + (-6)*(-6 - 2) + (3)*(2 - -6)) / 2

        = (0 + 48 + 24) / 2

        = 72/2

Newtons First Equation of motion can be applied and plugin in the given data the acceleration was found to be 2.03 m/s^2

Given Data

Time t= 3 seconds

Initial Velocity u = 0.8 m/s

Final Velocity v = 7 m/s

Acceleration a = ??

Applying the Newton's First equation of motion

v = u+at--------------1

Substituting our given Data

7 = 0.8+a*3

solving for acceleration a

7-0.9 = 3a

6.1 = 3a

divide both sides by 3 we have

a = 6.1/3

a = 2.03 m/s^2

Answer:

36 times.

Step-by-step explanation:

3/5=0.6

2/5=0.4

60*0.6=36

Scott would expect the wad of paper to land in the trash can approximately 36 times out of 60 throws. So, correct option is B.

To calculate the expected number of times the wad of paper would land in the trash can if Scott throws it 60 times, we can use the concept of probability.

Based on the given results, the probability of the wad of paper landing in the trash can is 3 out of 5 times (3 times in the trash can out of a total of 5 throws).

To find the expected number of successful throws (i.e., landing in the trash can) out of 60 throws, we can set up a proportion:

(Probability of success) = (Number of successful throws) / (Total number of throws)

3/5 = x/60

Now, cross-multiply and solve for 'x':

5x = 3 * 60

5x = 180

x = 180 / 5

x = 36

The correct answer is B. 36

This calculation is based on the assumption that the probability remains the same for each throw, which is the case for independent events like tossing a wad of paper.

Step-by-step explanation:

Use triangle ACD.

m<A m<C + m<ADC = 180

y + 70 + 42 = 180

y + 112 = 180

y = 68

Use parallel lines BF and CE.

m<ADC + m<BGD = 180
