You are trying to find the distance AB between two points on either side of a river. You
measure the following distance:

Answers

Answer:32ft

Step-by-step explanation: I missed this as well, ED and AB are the same and if you don’t read you skip over the fact ED equals 32ft. Since ED and AB equal eachother it would be 32ft

The value of AB = 32 feet

What is congruency ?

Congruent shapes are shapes that are exactly the same. The corresponding sides are the same and the corresponding angles are the same.

Given:

EC= 32 ft = BC

DC= 28 ft =AC

<ECD= <BCA

So, In ΔECD and ΔBCA

EC = BC

DC= AC

<ECD= <BCA

Thus, by SAS ΔECD ≅  ΔBCA

Hence, by CPCT : ED= BA = 32 ft.

David begins the summer with a savings of $54.00 more than Fatima. David’s job
pays $8.25 per hour. Fatima’s job pays $9.75. If they both work the same amount of
time each day, how many hours of work will it take David to have as much money as
Fatima? Write an inequality and then solve.

Answers

Answer:

36 hours (1 1/2 days, 351$ )

Step-by-step explanation:

create a linear system and solve.

8.25x + 54 = 9.75x

_______________

-8.25x -8.25x

_______________

54 = 1.5x

_______________

1.5 x = 54

_______________

÷ 1.5. ÷1.5

_______________

x = 36.

if you want to know how much money they will have at this time, just substitute the x value that you solved for back into the equation

x = 36 -> 8.25(x) + 54 = 9.75(x)

8.25(36) + 54 = 9.75(36)

297 + 54 = 351

351 = 351

________________________________

David's budget >= 54$

Fatima's budget >= 0$

The required inequality is 8.25x + 54 = 9.75x

It will take 36 hours for David to have as much as Fatima.

David :

Initial saving = 54

Pay per hour = $8.25

Fatima :

Pay per hour = $9.75

Let number of hours worked = x

David's total = $8.25x + 54

Fatima's total = 9.75x

In other to have the same amount :

8.25x + 54 = 9.75x

Collect like terms :

8.25x - 9.75x = - 54

-1.5x = - 54

x = - 54 / - 1.5

x = 36

Hence, it will take 36 hours for David to have as much as Fatima.

I need help! The 20% off sale is a better deal than the $200 rebate or $150 coupon for the $1,500 dining room set. Explain why this is the best deal for them. Are they under budget?

Answers

Answer:

See explanation

Step-by-step explanation:

The 20% off sale is a better deal because 20% off of $1500 will cost $1200. (See work).

However, the 200 or 150 dollars off will cost $1300-1350. Thus, the better deal for the dining room set is to use the 20% off.

If their budget is $1250, they will be $50 under budget because they would be paying $1200 for the set.

Work:

1500 x 20%

1500 x 0.20 = 300

1500-300= $1200

1500-150= 1350

1500-200= 1300

Yes, the Porters are under budget. The 20% off sale is the best deal because $1,500 times 0.20 is $300. $300 is a bigger discount than the $150 coupon and $200 rebate. $300 off $1,500 is $1,200, which is less than the amount budgeted.

· The senior class is planning an end of the year party to celebrate graduation. Their
total budget for food and drinks is $600. Each plate of food costs $5, and each drink
costs $1. Each person at the party gets one plate of food and one drink, with none
leftover. How many people went to the party?

Solve problem using systems of equations.

Answers

Answer:

100

Step-by-step explanation:

Because everyone had one plate and one drink, we can combine those individual prices.

5 + 1 = 6

Now we divide 600, the total cost, by 6, the cost for one person.

600 ÷ 6 = 100

So now we know that 100 people went to the party, as there was nothing left over.
