Answer:

Car As unit rate is --- ***57km/h***

Car Bs unit rate is --- ***70km/h***

Which car goes faster? --- ***Car B*

I hope this helps. u said 45 minutes, so i tried to some up with an answer. best of luck on ur work

Step-by-step explanation:

car a is 57 km in an hour, as 57t is equal to d. This, when d is 57 km will be 1 hr. So we are assuming that "t" is 1. Then d is 57. NOw lets check out car b. 140/2 is for 2 hrs, 210/3 for 3 hrs, and 280/4 for 4 hrs. This gives rate of 70 km in 1 hr.

Answer:

40

Step-by-step explanation:

Distance = 500 t

This equation means if we multiple 500 by the given time, we can determine the distance traveled.

Given in the question.

t = 8 hours

So we can substitute 8 into the equation.

Distance = 500 x 8

Distance = 4000 miles

Therefore, it traveled 4000 miles in 8 hours.

An expression is defined as a set of numbers, variables, and mathematical operations. The distance traveled by aircraft in 8 hours is 4,000 miles.

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

Given that the expression 500t gives the distance traveled by the aircraft in t hours. Therefore, the function can be written for distance as,

D(t) = 500t

where D is the distance in miles and t is the time in hours.

Now, To know the distance traveled by aircraft in 8 hours simply substitute the value of t as 8 in the given equation. Therefore, The distance traveled by the aircraft in 8 hours is,

D(t) = 500t

D(8) = 500(8)

       = 4,000 miles

Hence, the distance traveled by aircraft in 8 hours is 4,000 miles.

Answer:

12 seconds

Step-by-step explanation:

To do this you would take the rate of the ball, (the 3 m/s) and divide it from how big the hill is, (36 m)

36/3=12 seconds

So the ball would reach the bottom of the hill in 12 seconds

Answer: d = -1.2

Step-by-step explanation: First you combine like terms. You add 5 +2 which gives you 7, and then you subtract 9 from 5 which gives you -5d. Then you subtract 7 from 13 which gives you 6. Divide both sides by -5 and you get -1.2. Always make sure to check your answer by plugging your answer into the place of the d variable

Step-by-step explanation:

we can write the question out:

2              36

----     x     ------

9                1

We can now cross out divide 9 by 9 and 36 by 9:

2             36/9 = 4

----     x     ------

9/9 = 1        1

2       x      4

Given :

Shawn's family car holds 16 gallons of fuel.

Each day the car uses 0.8 gallons to get to school and back.

A warning light comes on when there is less than 1.5 gallons left in the fuel tank.

To Find :

How many days can Shawn drive the car before the warning lights come on.

Solution :

Let, after x days warning come.

So,

[tex]16 - 0.8x < 1.5\\\\16-1.5<0.8x\\\\0.8x > 14.5\\\\x > \dfrac{14.5}{0.8}\\\\x > 18.125[/tex]

Therefore, at 19th day the warning light will start glowing.

Hence, this is the required solution.

Answer:

when x = -3; y = -22/7

when x = 0;  y = -13/7

when x = 3;  y = -4/7

y = 3/7x - 13/7

x = 7/3y + 13/3

Step-by-step explanation:

x = -3;    3(-3) - 7y = 13; -9 - 7y = 13; -7y = 22; y = -22/7

x = 0;     3(0) -7y = 13; -7y = 13; y = -13/7

x = 3;     3(3) -7y = 13; 9 - 7y = 13; -7y = 4; y = -4/7

SOLVE FOR Y: 3x - 7y = 13; -7y = -3x + 13; y = 3/7x - 13/7

SOLVE FOR X: 3x - 7y = 13; 3x = 7y + 13; x = 7/3y + 13/3

Answer:

Option (1)

Step-by-step explanation:

From the picture attached,

Lines 'm' and 'n' are the parallel lines and 'r' is a transversal line intersecting these lines at two distinct points.

Therefore, both the angles will be congruent by the property of corresponding angles postulate.

By the converse of corresponding angles postulate,

If these angles are congruent then both the lines (m║n) will be parallel.

Option (1) will be the answer.

Answer:

5 1/4 inches

Step-by-step explanation:

In 1 week, 1 1/6 inches decreases

In 1/2 week, 7/6 /2 =7/12 inches decreases

In 4 weeks, 4* 1 1/6 = 4* 7/6 = 14/3 inches decreased

In 4 1/2 weeks, 7/12 + 14/3 = 7/12 + 56/12 = 63/12 = 5 3/12 = 5 1/4 inches decreased

Q

Step-by-step explanation:

I just know I guess

Answer:

I DONT KNOW WHAT IT IS BUT ITS NOT Q TRUST ME

Step-by-step explanation:

i ⁴³⁵ = i ⁴³²⁺³ = i ⁴³² • i ³

i ⁴³⁵ = i ⁴³² • i ³

i ⁴³⁵ = (i ⁴)¹⁰⁸ • i ³

i ⁴³⁵ = 1¹⁰⁸ • (-i)

i ⁴³⁵ = -i

The value of the imaginary number i⁴³⁵ is : i ⁴³⁵ = -i.

Here, we have,

To evaluate the expression i⁴³⁵, we need to understand the properties of the imaginary unit, denoted by i.

The imaginary unit i is defined as the square root of -1, meaning i² = -1.

When raising i to an exponent, we can use the pattern of powers of i to simplify the expression.

The pattern of powers of i repeats every four exponents:

i¹ = i

i² = -1

i³ = -i

i⁴ = 1

Since i⁴ = 1, we can divide the exponent 435 by 4 to find the remainder:

435 divided by 4 gives a remainder of 3.

Therefore, i⁴³⁵ is equivalent to i³.

Using the pattern of powers of i, we know that i³= -i.

So, i⁴³⁵ = -i.

i.e. we get,

i ⁴³⁵ = i ⁴³²⁺³ = i ⁴³² • i ³

i ⁴³⁵ = i ⁴³² • i ³

i ⁴³⁵ = (i ⁴)¹⁰⁸ • i ³

i ⁴³⁵ = 1¹⁰⁸ • (-i)

i ⁴³⁵ = -i
