JJ withdraws $20 from his bank account every week for lunch. Suppose he does not make any additional deposits or withdrawals. What integer represents the change in value of JJ's bank account after nine weeks?

Answers

Answer 1

Answer:

-118

Step-by-step explanation:

Since he is withdrawing, the value of 20 will be negative.

And if he is withdrawing $20 over nine weeks, then it is a multiplication problem.

So,

-20 x 9 = -118

The distance between Heysham and the Isle of Man is 80 km.
A hovercraft travels at 50 km per hour.
How long does the journey take?

Answers

50/1 =80/x
50x=80
Divide both sides of the equal sign by 50 to get variable by itself
x= 1.6
Your answer is 1.6 of an hour for the journey

Answer:

1 hour 36 minutes

Step-by-step explanation:

Amount of time the journey takes = 80km ÷ 50km/h

T = d/14000
d = T/14000
14000 = T/d
T = 14000/d
T = 14000d

Answers

It takes 6 hours to reach the destination when traveling at 388 mph.

Speed is the ratio of total distance traveled to the total time taken It is given by:

Speed = distance/time

Given that it takes 4 hours to reach a destination when travelling at 582mph, hence the distance is:

582 = distance / 4

distance = 2328 miles

If travelling at 388 mph, the time is:

388 = 2328 / time

time = 6 hours

Hence it takes 6 hours to reach the destination when traveling at 388 mph.

Which of the following statements is true in its conditional and converse forms?

If a polygon has 3 sides, then the sum of its interior angles is 180°.
If two angles are right angles, then they are congruent.
If B is the midpoint of AC¯¯¯¯¯¯¯¯, then AB = BC.

Answers

The converse statement involves switching the hypothesis and the conclusion of a conditional statement.

The correct statement is (d) If B is the midpoint of AC, then AB = BC.

The converse of the given conditional statements are:

If K is a midpoint, then K is between points J and LIf the sum of interior angles is  180°, then the polygon has 3 sidesIf two angles are congruent, then they are right anglesIf AB = BC, then B is the midpoint of AC

From the above statements, (a), (b) and (c) are not the same as the conditional statement, because:

Point K does not have to be between points J and L to be a midpoint.The sum of interior angles of all polygons (whether it has 3 sides or more) is 180 degreesCongruent angles may not be right angles

For option (d):

For B to be a midpoint of AC, it means that sides AB and BC are congruent.

Hence, the correct statement is (d)

are trucks?

Pls help me

Answers

Answer:

88 trucks

Step-by-step explanation:

Ratio of cars : vehicles = 5:13

Hence, the ratio of trucks : vehicles = 8:13

143/13 = 11

If the number of vehicles is 143,

we have to multiply both sides of the ratio by 11:

8*11 : 13* 11

88 : 143

Hence, there are 88 trucks for every 143 vehicles.

14) Andre went hiking by his house, The first trail he hiked took him 4.5 miles away from his
house. The second trail he hiked took him 2.4 miles closer to his house. The third trail
took him 1.7 miles further away from his house. After Andre hiked the three trails, how
far from his house was he?

Answers

Answer : 3.8 miles
Step by step explanation :
The calculation is the following :
4.5 miles of the first hike minus 2.4 miles of the second hike
4.5 - 2.4 = 2.1
Then you have to add those 2.1 miles the 1.7 miles of the third and last hike
2.1 + 1.7 = 3.8 miles

You have $75 in your bank account. Each week you plan to deposit $8 from your allowance and $25 from your paycheck. The equation b=75+(25+8)w gives the amount b in your account after w weeks. How many weeks from now will you have $270 in your bank account?

Answers

Answer:

Step-by-step explanation:

Combine the two sources of income (25 + 8) = 33

b = 75+ (33)w

Let b = 270

Solve for w

270 = 75 + 33*w           Subtract 75 from both sides

270 - 75 = 33w

195 = 33w                     Divide by 33

195/33 = w            

w = 5.91 weeks              

The question is what do you do now?

The answer should be that you round to the next week which means that it will take you 6 weeks to get just over 270 dollars.

The perimeter of an equilateral triangle is 12 inches. After a dilation, the
perimeter of the image is 42 inches. What is the scale factor of the dilation?

Based on the change in the perimeter, the scale factor of the dilation is 3.5.

The scale factor of the dilation refers to the number of times the triangle was dilated such that it went from 12 inches to 42 inches.

This dilation can be found as:

= Increased perimeter / Original perimeter

Solving for it would give:

= 42 / 12
