Step-by-step explanation:

If we are working in base five, then in the 1203, there would be 3 in the ones place. 3

In the 5 place, there is 0.

In the 25's place, there is a 2, which means 2*25=50

In the 125's place, there is a 1, 1*125=125.

125+50+3=178

Answer:

B. 178

Step-by-step explanation:

1203 to base 5 equals:

[tex](1 \times {5}^{3} ) + (2 \times {5}^{2} ) + (3 \times 1)[/tex]

[tex]125 + 50 + 3 = 178[/tex]

Answers

Answer: D. 140

Step-by-step explanation:

Goal: Find x and solve the equation

1) Since they are parallel angles, you can move QXY up to SQR.

Note: I don't really know how to explain this... Hope this is enough.

2) Set up the equation and solve

4x+40+2x-10 = 180

6x+30=180

6x = 150

x = 25

3) Solve the PQS equation

4x+40

4(25)+40 (Substitute x here.)

100+40

140

The answer would be D.one hundred and 40

Carl’s monthly income is $4,000. The circle graph below shows Carl’s monthly budget.

Part A: How much money did Carl budget for car payment each month?

Part B: How much money did Carl budget for food each month?

Answers

Answer:

$600 for car payment

$200 for food

Step-by-step explanation:

all you need to do is change the percent to a decimal 15% = 0.15 5% = 0.05

then multiply that decimal with the amount of money in this case, $4,000 so...

car payment = 0.15 × 4000 = 600

food = 0.05 × 4,000 = 200

Answer:

Part A: Carl spent $600 for car payment each month.

Part B: Carl spent $200 for food payment each month.

Step-by-step explanation:

Part A: 15% of $4000 which is 15% x 4000 = $600

Part B: Step 1 50+20+15+10=95

Step 2 95-100 is 5 which is 5%

Step 3 5% of $4000 which is 5% x 4000 = $200

Emilio has a gift card with $250 on it. He uses the gift card to buy 5 DVD's.

Adam has a gift card with $150 and uses it to purchase 4 DVD's.

If they both now have the same amount left on their gift cards, how much did each DVD cost?

Answers

Answer: Each DVD cost $100

Step-by-step explanation:

So it's a system of equations, where x = DVD price and y = remainder...

250 - 5x = y

150 - 4x = y

Now let's find x by making the y's cancel out.

In order to do this, multiply one equation by -1!

-250 + 5x = -y

150 - 4x = y

Which equals to...

-100 + x = 0

Add 100 to both sides...

x = 100

MEANING that each DVD cost $100. Quite pricey if you ask me!

$100 is the answer i believe
