Answer:

y = 8x +20

Step-by-step explanation:

The value of y for the given expression is y = 8x + 20. The correct option is A.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given expression is 1/4y - 2x = 5. The value of y for the expression is solved as below:-

1/4y - 2x = 5

( 1 / 4 )y = 2x + 5

y = 4 ( 2x + 5 )

y = 8x + 20

Therefore, the value of y for the given expression is y = 8x + 20. The correct option is A.

Answer:

4.1

Step-by-step explanation:

1.8 x 0.5 = 0.9

0.5 x 0.5 = 0.25

2(0.9 + 0.9 + 0.25) = 2(1.8 + 0.25) = 2(2.05)

2 x 2.05 = 4.1

Therefore the answer is 4.1

Step-by-step explanation:

SA = 2(hl+hw+lw)

It doesn't matter which specifically is the height or width or length in this case.

1.8 x 0.5 = 0.9

1.8 x 0.5 = 0.9

0.5 x 0.5 = 0.25

2(0.9 + 0.9 + 0.25) = 2(1.8 + 0.25) = 2(2.05)

2 x 2.05 = 4.1, which is the surface area.

Both are correct

Answer:

61 degrees

Step-by-step explanation:

Let's do this

So we know all the angles measure in a triangle will be 180 degrees

We have 56 and 63

To find the third, let's add and subtract

56+63=119

Now let's subtract from 180

So 180-119=61

The third angle measures 61 degrees

Now let's add them up and see if they total 180 degrees

So 56+63+61=180

Yay, we found the answer!

The answer is 61 degrees.

Step-by-step explanation:

Let Alyssa's horse's age be x .

Then :-

Alyssa's age = 2x

Age of her horse when it died = 24

Alyssa's age when her horse died =

[tex]2x \\ = 2 \times x \\ = 2 \times 24 \\ = 48 \: years[/tex]

∴ Alyssa was 48 years old when her horse Midnight died .

Answer:

29

Step-by-step explanation:

Alyssa was twice the age of midnight so 10 ÷2 =5(age gap)

Midnight died at 24 so Alyssa was 29 that time because

24+5(age gap) =29

Answer:

9/5 (K-273.15) + 32=F

Step-by-step explanation:

K=5 /9(F−32)+273.15

Subtract 273.15 from each side

K-273.15=5/9(F−32)+273.15-273.15

K-273.15=5/9(F−32)

Multiply by 9/5 on each side

9/5 (K-273.15)= 9/5 *5/9(F−32)

9/5 (K-273.15)=(F−32)

Add 32 to each side

9/5 (K-273.15) + 32=F−32 +32

9/5 (K-273.15) + 32=F

Answer:

f=1/59k+27.370339

Step-by-step explanation:

k=59(f−32)+273.15

Step 1: Flip the equation.

59f−1614.85=k

Step 2: Add 1614.85 to both sides.

59f−1614.85+1614.85=k+1614.85

59f=k+1614.85

Step 3: Divide both sides by 59.

59f/59=k+1614.85/59

f=1/59k+27.370339

Answer:

The probability that exactly one of the selected adults says that he or she was too young to get tattoos is 0.4096.

Step-by-step explanation:

Let X denote the number of adults who says that he or she was too young to get tattoos.

The probability of selecting an adults who says that he or she was too young to get tattoos is, p = 0.20.

Five adults who regret getting tattoos are randomly selected.

The events of any of these five adults regretting getting tattoos is independent of each other.

The random variable X follow a Binomial distribution with parameters n = 5 and p = 0.20.

Compute the probability that exactly one of the selected adults says that he or she was too young to get tattoos as follows:

[tex]P(X=x)={5\choose x}(0.20)^{x}(1-0.20)^{5-x}\\\\P(X=1)={5\choose 1}(0.20)^{1}(0.80)^{5-1}\\\\[/tex]

                [tex]=5\times 0.20\times 0.4096\\\\=0.4096[/tex]

Thus, the probability that exactly one of the selected adults says that he or she was too young to get tattoos is 0.4096.

Answer:

Graph attached.

Step-by-step explanation:

The product of slope of line (i) and slope of line (ii) should be equal to -1 (product of slopes of two perpendicular lines = -1)

i.e

Slope of line (i) × 2 = -1

Slope of line (i) = [tex]-\frac{1}{2}[/tex]

To find the equation of line (i), we need another point (x,y) on the line.

Slope (m) = change in y ÷ change in x = [tex]\frac{y - -3}{x - 0} = -\frac{1}{2}[/tex]

y = [tex]-\frac{1}{2} x[/tex] - 3

Answer:

The answer is "About 421.6 and 578.4 the middle of 95% of both the wires of the A business checked".

Step-by-step explanation:

The Mean = Median = Mode= 500 for company A  

It also will see company A as a regular delivery  

Mean > Median > Mode for the business B  

Company B would seem to have a correct warped delivery

The value of Z varies in the center of 95% of the wires: [tex](-1.96\ \ from \ \ 1.96)[/tex]

[tex]\text{The lower bound} = Mean - 1.96 \times \sigma[/tex]

                           [tex]= 500 - 1.96 \times 40 \\\\= 500 - 78.4\\\\= 421.6[/tex]

[tex]\text{The upper limit = Mean} + 1.96 \times \sigma[/tex]

                         [tex]= 500 + 1.96 \times 40 \\\\= 500 + 78.4 \\\\= 578.4[/tex]

Answer:

[tex] y = 15x + 20 [/tex]

x = 11, when y = 185

Step-by-step explanation:

Given:

(0, 20);

(2, 50)

Required:

Equation of the line;

Value of x, when y = 185

SOLUTION:

Equation of the line can be written using the slope-intercept formula, given as, [tex] y = mx + b [/tex].

m = slope = [tex] \frac{y_2 - y_1}{x_2 - x_1} =\frac{50 - 20}{2 - 0} = \frac{30}{2} = 15 [/tex]

b = y-intercept = the pointt at which the line cuts the y-axis = 20

Plug in the value into the formula to get the equation:

[tex] y = mx + b [/tex]

[tex] y = 15x + 20 [/tex]

Use this equation to solve for x, when y = 185

[tex] y = 15x + 20 [/tex]

[tex] 185 = 15x + 20 [/tex] (substitution)

[tex] 185 - 20 = 15x + 20 - 20 [/tex]

[tex] 165 = 15x [/tex]

[tex] \frac{165}{15} = \frac{15x}{15} [/tex]

[tex] 11 = x [/tex]

x = 11, when y = 185
