Step-by-step explanation:

Answer:

3 1/3 hours

Step-by-step explanation:

Let the total work done be x

For Sergei

In 5 hours, amount of work done by Sergei = x

in 1 hour ,amount of work done by Sergei = x/5

Similarly for Irina

In 10 hours, amount of work done by Irina = x

in 1 hour ,amount of work done by Irina = x/10

In 1 hour , work done by both of them together = work done by Sergei in 1 hour + work done by Irina in 1 hour = x/10 + x/5 = (x + 2x)/10 = 3x/10

Thus,

we can say that

time taken to do 3x/10 work by both of them together = 1 hour

since the total work is x , to find time taken to do total work together

we divide both side of equation with 3/10

time taken to do 3x/10/ (3/10) work by both of them together = 1/(3/10) hour

time taken to do x work by both of them together = 10/3 hours = 3 1/3 hours.

Answer:

a. Jack's rate of change is 0.7 miles per hour

b. Jack is hiking upwards

Step-by-step explanation:

a. 0.7 is his slope (a.k.a change) 0.7 miles because that is how distance is being measured and t is the time in hours

b. since his slope is positive I am assuming that he is going upwards like (/) the line is raising

Answer:

The required coordinates are;

A''(-3, -5), B''(0, -4), C''(0, -2), and D''(-3, 0)

Step-by-step explanation:

The given coordinates of the trapezoid ABCD are;

A(-5, -3) B(-4, 0), C(-2, 0) and D(0, -3)

Therefore, we have;

For a rotation 90° counterclockwise, we have for a given coordinates of the preimage (x, y) after a rotation 90° counterclockwise, the image will be located at (y, -x)

Therefore, for the points of the trapezoid, we have;

Preimage A(-5, -3) rotated 90° counterclockwise gives image A'(-3, 5)

Preimage B(-4, 0) rotated 90° counterclockwise gives image B'(0, 4)

Preimage C(-2, 0) rotated 90° counterclockwise gives image C'(0, 2)

Preimage D(0, -3) rotated 90° counterclockwise gives image D'(-3, 0)

For a reflection across the x-axis gives the transformation, preimage location (x. y), image location after reflection (x, -y)

Therefore, we have;

For the point A'(-3, 5), reflection across the x-axis gives A''(-3, -5)

For B'(0, 4), reflection across the x-axis gives B''(0, -4)

For C'(0, 2), reflection across the x-axis gives C''(0, -2)

For D(-3, 0), reflection across the x-axis gives D''(-3, 0)

Therefore, the required coordinates are;

A''(-3, -5), B''(0, -4), C''(0, -2), and D''(-3, 0).

Answer:

Step-by-step explanation:

to find the slope, we can take any two points, and find the slope between then

e.g.

(0, -3) and (20, 2) => [tex]m = \frac{y_2-y_1}{x_2-x_1} = \frac{2-(-3)}{20-0} = \frac{1}{4}[/tex]

now we can test other points, and if the slopes are consistent, we can determine the overall slope

(4, -2) and (16, 1) => [tex]m = \frac{y_2-y_1}{x_2-x_1} = \frac{1-(-2)}{16-4} = \frac{1}{4}[/tex]

(8, -1) and (12, 0) => [tex]m = \frac{y_2-y_1}{x_2-x_1} = \frac{0-(-1)}{12-8} = \frac{1}{4}[/tex]

yep, it's consistent

the slope is [tex]\frac{1}{4}[/tex]

Answer:

B.

Step-by-step explanation:

Answer:

Graph D

Step-by-step explanation:

First we need to solve the equation to get it in slope-intercept form(y= mx + b)

Equation: y - 4 = 2(x - 1)

Distribute;

y - 4 = 2x - 2

Add 4 to both sides;

y = 2x + 2

The slope is 2 and the y-intercept is 2. The starting point is 2 and the rate of change is 2

Answer: $430.90

Step-by-step explanation:

Given formula : [tex]V = P e^{ r t}[/tex], where V is the value of the account in t years, P is the principal initially invested, e is the base of a natural logarithm, and r is the rate of interest.

Given: P= $290 , r=2.2% = 0.022 [divide percent by 100 to remove percent sign '%']

Also, t=18 years

Now, [tex]V=290e^{0.022\times18}=290e^{0.396}[/tex]

[tex]=290\times1.48586931755\approx\$430.90[/tex]

Hence,  the amount of money in the account after 18 years. = $430.90

Step-by-step explanation:

Answer

(∠ABC) 108 (for all)

(∠ACB) 27 (for all)

(∠CAB) 45 (for all)

Step-by-step explanation:

The measures of the angle can be found by calculation using sine rule and

cosine rule.

The measures of the required angle are;

∠ABC = ∠A'B'C' = ∠A'₁B'₁C'₁ ≈ 119.74°

∠BCA = ∠B'C'A' = ∠B'₁C'₁A'₁ ≈ 37.88°

∠BAC = ∠B'A'C' = ∠B'₁A'₁C'₁ ≈ 22.38°

By calculation, we have;

∠A'₂B'₂C'₂  ≈ 105.26

∠B'₂C'₂A'₂ ≈ 53.97°

∠B'₂A'₂C'₂  ≈ 20.77°

Reasons:

Length of AB = Distance between points B(-3, -3), A(-6, -1)

AB = √((-3 - (-6))² + (-3 - (-1))²) = √(13)

Length AC = Distance between points A(-6, -1), and C(-1, -2)

AC = √((-6 - (-1))² + (-1 - (-2))²) = √(26)

Length BC = Distance between points B(-3, -3), and C(-1, -2)

BC = √((-3 - (-1))² + (-3 - (-2))²) = √(5)

By cosine rule, we have;

AC² = BC² + AB² - 2×BC×AB ×cos∠ABC

cos∠ABC = (AC² - (BC² + AB²))/(2×BC×AB) = (26 - (13 + 5))/(-2×√(5)×√(13))

∠ABC = 119.74

AC/(sin(119.74) = AB/(sin(∠BCA))

(√(26))/(sin(172.97) = √(13)/(sin(∠BCA))

sin(∠BCA) = √(13)/((√(26))/(sin(119.74))

∠BCA = 37.88°

∠BAC = 180 - (119.74 + 37.88) = 22.38°

Length of segment B'₁C'₁ = √5

Length of segment B'₁A'₁ = √(13)

Length of segment A'₁C'₁ = √(26)

By calculation, we have;

Length A'₂B'₂ = √(26)

Length A'₂C'₂ = √(37)

Length B'₂C'₂ = √(5)

cos∠A'₂B'₂C'₂  = (37 - (26 + 5))/(-2 × √(26) × √(5))

∠A'₂B'₂C'₂  = 105.26

(√(37))/(sin(105.26) = √(26)/(sin(∠BCA))

sin(∠BCA) = √(26)/((√(37))/(sin(105.26))

∠B'₂C'₂A'₂ = 53.97°

∠B'₂A'₂C'₂  = 180 - (105.26 + 53.97) = 20.77

Therefore, by similar triangles, we have;

∠ABC = ∠A'B'C' = ∠A'₁B'₁C'₁ ≈ 119.74°

∠BCA = ∠B'C'A' = ∠B'₁C'₁A'₁ ≈ 37.88°

∠BAC = ∠B'A'C' = ∠B'₁A'₁C'₁ ≈ 22.38°

By calculation, we have;

∠A'₂B'₂C'₂  ≈ 105.26

∠B'₂C'₂A'₂ ≈ 53.97°

∠B'₂A'₂C'₂  ≈ 20.77°

Answer:

20% percent is the total discount

Step-by-step explanation:

Answer:

The answer to your question is 20%

Step-by-step explanation:

Think of it as a simple addition problem and take the percentages out of it. Since we want to know what the total discount of the shirt is we could take the original discount of the store (10% or 10) and then we could take your coupon for (10% or 10) and add them together to get the total discount of the shirt. That's a really exaggerated way to put it so think of it like this:

10%+10%= 20%

Answer:

Page 116

Step-by-step explanation:

Parker started on page 50 at t = 0 days, and he will read 11 pages per day. Therefore the page that Parker will be on after t days is:

P = 11t + 50

Grayson started on page 8 at t = 0 days, and he will read 18 pages per day. Therefore the page that Grayson will be on after t days is:

G = 18t + 8

To find the number of days, t, after which Parker and Grayson will be on the same page, set the two equations equal to each other and solve for t :

11t + 50 = 18t + 8

     -18t        -18t                                                        ( subtract 18t )

-7t + 50 = +8

      -50     -50                                                          ( subtract 50 )

       -7t  =  -42

       -7t =  -42

        -7        -7                                                          ( divide by -7 )

           t  = 6

Since both equation values are equal when t = 6, we know Parker and Grayson will be on the same page after 6 days.

Now find the page number both Parker and Grayson will be on at this time. You can plug t = 6 into either equation.

P  = 11(6) + 50 = 116

G  = 18(6) + 8 = 116

Parker and Grayson are both on page 116 after 6 days.

Final Answer:

P  = 11t + 50            G  = 18t + 8

Using the power rule

Answer:

Devon's sister is NOT correct

Units price=0.50

Step-by-step explanation:

Based on the information given Devon's sister is NOT correct

For Devon's sister to find the correct price what she has to do is to find the unit price by dividing the total cost of the amount of $2.99 by the number of items which is 6.

Using this formula

Units price=Total cost/ Numbers of items

Where,

Total cost=$2.99

Numbers of items=6

Let plug in the formula

Units price=$2.99/6

Units price=0.498*100

Units price=49.8

Units price=0.50 Approximately

Therefore Devon's sister is NOT correct and the correct price is 0.50
