Answer:

70 mph, Yes the insurance company Will provide a full replacement for her car.

Step-by-step explanation:

To get the equation lets use direct variation, and K for the constant, S for the speed, and D for the stopping distance. d=ks^2, find s, or the speed, which will get the equation s=√d/k. The speed s, is equal to the square root of the stopping distance divided by the constant. Next, lets plug in the numbers s=√245/.05. Then, we find the square root of each number, √245 = ~15.652, and √.05 ~.2236  s=15.652/.2236 then divide, which will equal s=70. 70<80, so the insurance company will provide a full replacement for her car.

Answer:

Length of longest side is 10.5 inches

Step-by-step explanation:

Let the shortest side of the quadrilateral be x inches

The length of the consecutive sides will be;

x , x + 1 , x + 2 and x + 3 inches

By adding all

together, we get the perimeter of the quadrilateral

so;

x + x + 1 + x + 2 + x + 3 = 36

4x + 6 = 36

4x = 36-6

4x = 30

x = 30/4

x = 7.5 inches

The longest side is x + 3 = 7.5 + 3 = 10.5 inches

The value of n in the given congruent triangle is 6.

Congruent triangles have the same corresponding angle measures and side lengths.

Given that two congruent triangles, Δ ABC ≅ Δ XYZ,

Since, we know that, corresponding parts of congruent triangle are equal,

Therefore,

AB = XY

5n+8 = 38

5n = 30

n = 6

Hence, the value of n in the given congruent triangle is 6.

Answer:

Step-by-step explanation:

Let the total current = 12A

If there are there lamps 6.0 Ω, 4.0 Ω and 2.0 Ω in series,

a) The total resistance in series connected circuit will be:

Rt = R₁+R₂+R₃

Rt = 6+4+2

Rt = 12Ω

b) According to ohm's law, the voltage drop is expressed as V = IR

I is the current in each lamps

Note that the same current flows in the resistors for series connection

R are the resistances

For the 6Ω, resistor

V = IR

V = 12(6)

V = 72V

The voltage drop across it is 72V

For the 4Ω, resistor

V = IR

V = 12(4)

V = 48V

The voltage drop across it is 48V

For the 2Ω, resistor

V = IR

V = 12(2)

V = 24V

The voltage drop across it is 24V

Answer:

A=200 ft²

Step-by-step explanation:

let the Length be L and the Width be W

We know that Perimeter = Length + Length + Width + Width

or,

Perimeter = 2(L + W)  

given that Perimeter = 60 ft,

60 = 2(L+W)    (divide both sides by 2)

60/2 = (L+W)

L + W = 30 ---------------------eq 1

we are further given that the length is twice the width, or,

L = 2W ---------------------- eq 2

substituting eq2 into eq 1,

L + W = 30

(2W) + W = 30

3W = 30

W = 10  (substitute this into eq 2)

L = 2W

L = 2(10)

L = 20

Area = Length x Width

= 20 x 10

= 200 ft²

Answer:

$6.60

Step-by-step explanation:

This is an incomplete question. I have however searched for the concluding parts and same attached as seen below.

First, we need to calculate the costs for both shoes rented by Dorian and Jack.

Member's cost for each shoe rentage is $2.95 , and since both rents the shoe at same cost, therefore,

Cost = $2.95 + $2.95 + $7.50

Cost = $13.40

To get the balance that Jack should receive, we will simply deduct the cost from the initial $20 member cost, hence;

Balance = $20 - $13.40

Balance = $6.60.

Therefore, the change that should be received by Jack is $6.60

Answer: All of the above

Step-by-step explanation:

The formula for the standard error of the mean is:

σM =σ/√N

where,

σM = standard error of the mean

σ = standard deviation of sample

√N = square of sample size

As the sample size of a population rises, it should be noted that the standard error of the mean will decrease. This is due to the fact that when there's an increase in sample size, there'll be cluster of the sample mean around the population mean.

Also, the the standard error of the mean measures the variability of the sample mean from sample to sample and is never larger than the standard deviation of the population.

Therefore, the answer will be "all or the above".

The Pythagoras theorem is not applicable in 24, 22, and 40 thus (D) will be not the side of the right angle triangle.

A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.

There are many types of triangles such that right-angle triangles, equilateral triangles, and much more.

The Pythagoras theorem is given as,

Hyp² = base² + perp²

Since the hyp is the biggest side thus it can be said to be as,

Biggest side² = (smaller side 1)² + (smaller side 2)²

In the  24, 22 and 40,

40² ≠ 22² + 24² thus it will not right an angle triangle,

Hence "In 24, 22, and 40, the Pythagorean theorem is not applicable so it will be not a right angle triangle".

Answer:

GH¢60

Step-by-step explanation:

Alex puts 1/4 1of his money in savings and uses 1/( 2) of the remaining money to pay back her sister. If she has GH¢15 left, how much did she have at first?

Let the Total amount of Alex money = 1

We are told that she has GH¢15 left,

Hence, we find the fraction of the money she has left

1 - (1/4 + 1/2)

1 - 3/4

= 1/4

The fraction of the amount she left = 1/4

Let x represent the total amount of money that Alex had

1/4 × x = GH¢15

x / 4 = GH¢15

Cross Multiply

x = 4 × GH¢15

x = GH¢60

Therefore, Alex had GH¢60 at first

Step-by-step explanation:

1) 3x10=30 so 30 is how much money he needs

2)30-23=7 so 7 is how much he needs to borrow

Answer:

$7

Step-by-step explanation:

The reason is because three medium pepperoni pizzas cost $30, because you have to multiply $10x3 since each pizza cost $10. He already has $23 dollars in his pocket. You have to subtract his total value which is $23 from $30 to get $7.
