Answer:

speed=distance/time

8=distance/15

120km= distance

Step-by-step explanation:

Jacob must leave 3.5 hours earlier than Anela to arrive at same time.

The distance traveled by an object in relation to the amount of time it takes to travel that distance is one way to define speed. Simply put, it is a measurement of an object's speed without providing direction. The term "velocity" refers to the speed at which we can obtain direction.

Given Anela distance to Brady = 375 km

speed of Anela = 75 km/hr

time taken by Anela is distance/speed

time taken by Anela = 375/75 = 5 hours

total time taken by time taken by Anela = 5 hours + 30 minute

30 minutes = .5 hours

total time taken by time taken by Anela = 5 hours + 0.5 = 5.5 hours

Jacob distance to Brady = 600 km

distance covered in 2 hours with speed 90 km/hr

= speed x time = 90 x 2 = 180 km

distance left = 600 - 180 = 420 km

time taken for 420 km at speed 70 km/hr

= 420/70 = 6 hours

total time taken by Jacob = 2 + 1 + 6 = 9 hours

difference in time of Jacob and Anela = 9 -5.5 = 3.5 hours

Hence Jacob should leave 3.5 hours early.

Answer:

A = 42.5 yd²

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )

Here b = 17 and h = 5 , then

A = [tex]\frac{1}{2}[/tex] × 17 × 5 = [tex]\frac{1}{2}[/tex] × 85 = 42.5 yd²

Hey there!

2(p + 1) + 8(p - 1) = 5p

2(p) + 2(1) + 8(p) + 8(-1) = 5p

2p + 2 + 8p - 8 = 5p

10p - 6 = 5p

SUBTRACT 5p to BOTH SIDES

10p - 6 - 5p = 5p - 5p

SIMPLIFY IT!

5p - 6 = 0

ADD 6 to BOTH SIDES

5p - 6 + 6 = 0 + 6

CANCEL out: -6 + 6 because it gives you 0

KEEP: 0 + 6 because it helps solve for the p-value

5p = 0 + 6

5p = 6

DIVIDE 5 to BOTH SIDES

5p/5 = 6/5

CANCEL out: 5/5 because it gives you 1

KEEP: 6/5 because gives you the result of the p-value

SIMPLIFY IT!

p = 6/5

Therefore, your answer is: p = 6/5

Good luck on your assignment and enjoy your day!

Answer:

x=34º

Step-by-step explanation:

a line always = 180º

so y+81=180

y=99º

a triangle is also always 180º total

so x+y+47=180

x+99+47=180

x+47=81

The total cost of pizza and drinks, is an illustration of a linear function.

The model that represents the situation is: [tex]\mathbf{10 + 3d = 19}[/tex]

The given parameters are:

[tex]\mathbf{Total =19}[/tex]

[tex]\mathbf{1\ pizza =10}[/tex]

[tex]\mathbf{1\ drink =d}[/tex]

The cost of 3 drinks will be 3d

The total cost would then be:

[tex]\mathbf{Total = 10 + 3d}[/tex]

Substitute 19 for Total

[tex]\mathbf{10 + 3d = 19}[/tex]

Rewrite the above equation as:

[tex]\mathbf{3d + 10 = 19}[/tex]

Hence, the model that represents the situation is: [tex]\mathbf{10 + 3d = 19}[/tex]

Step-by-step explanation:

Use the slope formula:

Answer:

D. The relationship is linear; y – 5 = 2(x + 7).

Step-by-step explanation:

The correct answer is:

The relationship is linear, and the equation is  

y-5 = 2(x+7).

Explanation:

To determine if the relationship is linear, we find the slope between each pair of points.  Slope is given by the formula:

The slope between the first two points is given by:

The slope between the second pair of points is given by:

The slope between the third pair of points is given by:

Since the slope is the same throughout the data, the relationship is linear and the slope is 2.

To write the equation, we use point-slope form, which is:

y-y₁ = m(x-x₁)

Using the first point, we have:

y-5 = 2(x--7)

y-5 = 2(x+7)

The answer is The relationship is linear; y - 5 = 2(x + 7).

Answer: w is 1.6 or. -5.6

Step-by-step explanation:

• I guess the question asks to find the value of w

[tex]{ \rm{3w + {w}^{2} + 1 = 10 - w }}[/tex]

• arrange the equation in a quadratic equation format. i.e; ax² + bx + c = 0
