Jessie is completing a mental rotation experiment. her reaction time will be fastest when the objects are rotated: 120 degrees. 180 degrees. 240 degrees. 60 degrees.

Answers

Answer 1

60 degrees it will take you longer to rotate this physical object by 180 degrees than to rotate it 90 degrees. your mental image should operate the same way the physical objects operate. then it will take you longer to rotate the mental image 180 degrees then rotate it 90 degrees. the dependent variable was reaction time not accuracy.

The diagram shows a trapezium ABCD in which BC parallel to AD

Answers

Answer:

if its the diagram i think then:

f = 6cm

g = 8cm

Step-by-step explanation:

square = 48cm²

triangle = 12cm²

24 / 4 = 6

AD = 6cm

BC = 6cm

CD = 48 / 6 = 8cm

CD = 8cm

f = 6cm

g = 8cm

In geometry, a quadrilateral with at least each pair of parallel sides is referred to as a trapezoid. Therefore, the length of BC is 6cm and the length of CD is 8cm.

What is trapezium?

In geometry, a quadrilateral with at least each pair of parallel sides is referred to as a trapezoid both Canadian and American English, and perhaps a trapezium in British as well as other forms of English. In Euclidean geometry, a trapezoid is a convex quadrilateral by definition.

The bases of a trapezoid are the parallel sides. If the remaining two sides are parallel, they are referred to as the legs; if not, the trapezoid is indeed a parallelogram, with 2 sets of bases. A trapezoid without equal-sized sides is called a scalene trapezoid.

area of square = 48cm²

area of triangle = 12cm²

24 / 4 = 6

AD = 6cm

BC = 6cm

CD = 48 / 6 = 8cm

CD = 8cm

f = 6cm

g = 8cm

Therefore, the length of BC is 6cm and the length of CD is 8cm.

Division is the process of dividing a number by a given number.

Given that, the length of the wire is 132 inches.

Now, the wire is cut into 9 equal pieces, therefore, the length of each piece is:
132/9

= 14.7 inches

The following section is a statement from the rental agreement Tim signed when he rented his car this past weekend. "Upon checkout, the fuel level of the vehicle will be determined by turning the vehicle on and visually inspecting the fuel gauge. The approximate fuel level will be recorded on the Check-Out sheet and verified with initials by the vehicle Renter. One copy of the Check-Out sheet will be given to the customer. Another copy will be kept with the on-site records of the vehicle. "The rented vehicle must be returned with a minimum fuel level the same as that indicated on the Check-Out sheet. A vehicle returned with a fuel level less than the approximate level indicated on the Check-Out sheet will be completely refueled with on-site pumps. The price of the fuel used to refuel the vehicle will be added to the Renter's total charge at a cost of $4.50 per gallon plus a $5.00 refueling charge." Tim is running extremely late and has just 5 minutes to return his rental car to the agency. The fuel tank in the car is half empty. It was full when he picked it up. (The car has a 12-gallon fuel tank.) He doesn't think he can get gas and get to the agency to return the car in time. Returning the car a day late will result in an extra daily rental charge of $32.00 and refueling the car on his own will cost $2.59 per gallon at the local gas station. Which of the following statements is true?
a. It would be cheaper to refuel the car and return it a day late.
b. It would be cheaper to return the car on time and pay the refueling costs.
c. It would cost about the same to return the car on time without gas or one day late with gas.
d. Tim is not responsible for refueling the car when he returns it.

Answers

It is cheaper for Tim to return the car on time and pay the refueling costs. If the gas tank on the car is half empty and the rental agency charges $4.50 per gallon the costs to refill for him would be. $27.00 plus the $5.00 refueling fee. This would equal $32.00. If Tim returns the car late, he faces a $32.00 charge including the cost to refuel the car on his own. The cost of returning the car a day late is not the same costs as returning the car on time.

Start by adding 20 to both sides to isolate '7b'. This gives you 7b = 3b + 32.

Next, Subtract 3b from both sides in order to make it so that the variable, which is 'b' in this case, is on one side of the equation.

This gives you 4b = 32.

Now divide both sides by 4 to cancel out 4b (opposite of multiplication is division).

This brings you to the answer b = 8 (32 divided by 4 is 8).

Item 19 You pay $40 each month for satellite TV, plus $3.50 for every movie you purchase. Write and solve an equation to find the number of movies purchased during a month with a total bill of $57.50.

Answers

Let x be the number of movies purchased. If each movie you purchase costs $3.50 dollars, this means that the total cost of x movies in one month is $3.50x
In addition, you have to pay $40 for satellite TV. We can now find an equation to find the total cost per month:
40 + 3.50x

Now, by hypothesis, you paid $57.50 during a month as a total bill.
Which means that 40 + 3.50x = 57.50
We need to find the number of movies purchased during that month, or, in mathematical words, we need to solve for x.

40 + 3.50x = 57.50

First, let's put the variables apart and the numbers apart by subtraction 40 from each side, so we get:
40 - 40 + 3.50x = 57.50 - 40
3.50x = 17.50

Now divide both sides by 3.50
(3.50x)/(3.50) = 17.50 / 3.50
x = 5

So, during that month, you purchased 5 movies.

Hope this helps! :)

you borrow $200 from a friend to help pay for the new laptop computer. You pay your friend $12 per week. Write and solve an inequality to find when you will owe tour friend less than $60.

Answers

Final answer:

You will owe your friend less than $60 if you pay them $12 per week for more than 11.67 weeks, which means you'll need to make payments for at least 12 full weeks.

Explanation:

To solve the problem of when you will owe your friend less than $60, we need to set up and solve an inequality.

The amount owed after any number of weeks can be represented by the initial debt of $200 minus the total amount paid off, which is $12 times the number of weeks.

If we let x represent the number of weeks, the inequality we need to solve is 200 - 12x < 60.

To solve this inequality, we subtract 200 from both sides, getting -12x < -140.

Then, we divide both sides by -12, remembering to reverse the inequality sign because we are dividing by a negative number, which gives us x > 11.67.

Since we can't pay off part of a week, we would need to pay your friend for at least 12 full weeks to owe less than $60.

Final answer:

To find when you will owe less than $60, set up the inequality 200 - 12w < 60. After simplifying, we see that it will take just over 11.67 weeks, so you will owe less than $60 after making payments for 12 weeks.

Explanation:

To solve the problem at hand, we need to create an inequality to represent the situation where you will owe less than $60 to your friend. Let's denote the amount owed each week with w and the total amount owed with A. You start with an initial debt of $200, and each week you pay off $12. The inequality we are trying to establish is when the total amount owed will be less than $60.

The inequality will be in the form of A - 12w < 60, where A is the initial amount of $200 and w represents the number of weeks. Plugging in $200 for A, we get 200 - 12w < 60.

To solve for w, we'll perform the following steps:

Subtract $200 from both sides to isolate the variable term: -12w < -140.

Since we are dividing by a negative number, remember to flip the inequality sign: w > 140/12.

Simplify the fraction to get the minimum number of weeks: w > 11.67.

You will owe your friend less than $60 after roughly 12 weeks since fractions of a week don't apply in the context of a weekly payment schedule.

The pitch of a roof is its slope. The roof of a home rises vertically a distance of 8 ft through a horizontal distance of 15 ft. Find the pitch of the roof.

Answers

since slope is rise/run so by the problem, it is 8/15=.533ft

The pitch of a roof of a home rises vertically a distance of 8 ft through a horizontal distance of 15 ft is 0.53.

What is Slope?

The slope of line is a measure of its steepness.

Given that;

Vertical distance (rise) = 8 feet

Horizontal distance (running) = 15 feet

Now, To find the pitch (slope) of the roof, we would use the following formula:

Slope is the ratio of the vertical distance measured to the horizontal distance measured.

Hence, The pitch (slope) of a roof is given by the formula;

Pitch = V / R

Where:

V is the rising vertical distance of an object.

H is horizontal distance an object runs through.

Hence, Substituting the given parameters into the formula, we have;

Pitch = 8/15

= 0.53

Thus, Pitch (slope) = 0.53

So, The pitch of a roof of a home rises vertically a distance of 8 ft through a horizontal distance of 15 ft is 0.53.
