1 answer:

5 0

Answer:
v = 18

Explain:
Equation; 4v = 72

Begin by dividing both sides
by 4 and isolating the v
v = 18

hopefully this helps you with your problem!

When visiting his parents, Tyler drives at an average speed of 42 km/h through urban areas and at an average speed of 105 km/h o

MaRussiya [10]

Answer:

168 km

Step-by-step explanation:

Let x represent the distance Tyler drives at the slower speed, and let y represent the distance at the higher speed. Using time = distance/speed, we can write equations for the total travel time:

x/42 +y/105 = 2.5

x/28 +y/60 = 4.0 . . . . . 1.5 hours more than the usual 2.5 hours

Multiplying the first equation by 210, we have ...

5x +2y = 525

Multiplying the second equation by 420, we get ...

15x +7y = 1680

Subtracting 3 times the first of these equations from the second, we have ...

(15x +7y) -3(5x +2y) = (1680) -3(525)

y = 105

Putting this into the very first equation, we get ...

x/42 + 105/105 = 2.5

x/42 = 1.5 . . . . . . subtract 1

x = 63 . . . . . . . . .multiply by 42.

The total distance to Tyler's parents' house is ...

63 km + 105 km = 168 km

Please help me out thanks

Answer:

Step-by-step explanation:

Since the angle that is touching each other shows that it is equal, the lines also show equality. So the number of lines in one of them is the same length in the other.

What is the cube root of 27a^12

tino4ka555 [31]

ANSWER

$3{a}^{4 }$

EXPLANATION

The cube root of

$27 {a}^{12}$

$\sqrt[3]{27 {a}^{12} }$

This is the same as:

$(27 {a}^{12} )^{ \frac{1}{3} }$

$( {3}^{3} ({a}^{4})^{3} )^{ \frac{1}{3} }$

$= (3{a}^{4} )^{3 \times \frac{1}{3} }$

$= 3{a}^{4 }$

PLEASE HELP 8th GRADE MATH QUESTION OVER HERE!!!

The side AB measures option 2. $\sqrt{20}}$ units long.

Step-by-step explanation:

Step 1:

The coordinates of the given triangle ABC are A (4, 5), B (2, 1), and C (4, 1).

The sides of the triangle are AB, BC, and CA. We need to determine the length of AB.

To calculate the distance between two points, we use the formula $d=\sqrt{\left(x_{2}-x_{1}\right)^{2}+\left(y_{2}-y_{1}\right)^{2}}.$

where ( $x_{1},y_{1}$ ) are the coordinates of the first point and ( $x_{2},y_{2}$ ) are the coordinates of the second point.

Step 2:

For A (4, 5) and B (2, 1), ( $x_{1},y_{1}$ ) = (4, 5) and ( $x_{2},y_{2}$ ) = (2, 1). Substituting these values in the distance formula, we get

$d=\sqrt{\left(2-4\right)^{2}+\left(1-5}\right)^{2}} = \sqrt{\left(2\right)^{2}+\left(4}\right)^{2}}=\sqrt{20}}.$

So the side AB measures $\sqrt{20}}$ units long which is the second option.
