The perimeter of the triangle is 350 units. Find the measure of each side (label your answers).

WITCHER [35]

Answer:

125, 105, 120

Step-by-step explanation:

You would first make an equation with what you know:

x + 45 + x + 25 + x + 40 = 350.

Now, you would simplify and add like terms.

3x + 110 = 350

Now, you would subtract 110 from both sides.

3x = 240

Now, you would divide both sides by 3.

x = 80

Now that you know what x is, simply plug it in to the respective equations for all three sides.

x + 45 would become 80 + 45, and add up to 125.

x + 25 would become 80 + 25, and add up to 105.

x + 40 would become 80 + 40, and add up to 120.

To check your work, you would now add the three totals.

125 + 105 + 120 = 350.

Answer:

Step-by-step explanation:

We are given that a graph which shows the number of beads used for varying cord lengths.

The graph

$y=2.52x+1.61$

We have to find the number of beads that she can used for cord length 32 in.

Substitute the value x=32

Then, we get

$y=2.52(32)+1.61=82.25$

After round to unit place then, we get

y=82

Hence, the best estimate she can used for number of beads =82

Answer: 82

Carl wants to buy a television that costs $500, including taxes. To pay for the television , he will use a payment plan that req

Harrizon [31]

Answer:

(B) 12%

Step-by-step explanation:

Original cost of the television = $500

Cost using the payment plan = Down payment + EMI's for 6 months

= $124 +72.5*6

= $560

Percentage increase = $\frac{New cost (using payment plan)-original cost}{original cost}*100$

= $\frac{560-500}{500} *100$

= 60/5

= 12%

Hence, the percent increase from the original cost of the television to the cost of television using the payment plan = 12% (C)
