find the perimeter of triangle whose sides are 5.2cm, 7.8 cm and 4cm.​

Answer:

164

Step-by-step explanation:

Answer:

Your answer is 164

Step-by-step explanation:

You add all the numbers and then divide by 5. And you will get 164.2 and you just round up to 164

So here is the work

149+183+149+193+147=821

821/5=164.2

164.2=164

Answer:y=-x

Step-by-step explanation:

Answer:

the simple interest here would be $220. the total amount he will receive is $2,420.

Step-by-step explanation:

to find how much interest Dan has, you use the formula,

simple interest = principal * interest rate * time

now we substitute the numbers in.

simple interest = $2,200 * 5% * 2

since the rate is a percentage, we have to convert it into a decimal.

simple interest = $2,200 * 0.05 * 2

let's do this step by step.

simple interest = $2,200 * 0.05 * 2

simple interest = $110 * 2

simple interest = $220

to find out how much Dan will earn after two years, we have to find the total amount by adding the interest and the amount of principal.

since we now know the interest, let's add it by the principal.

$220 + $2,200 = $2,420

Therefore, Dan will have $2,420 after two years.

Answer:

14.28%

Step-by-step explanation:

here's your solution

=> price of milk before = ₹28

=> price of milk after increasing = ₹32

=> increased in price = ₹32 - ₹28 = ₹4

=> now , increased percentage= 4/28*100

=> 14.28%

Answer:

7 runners

Step-by-step explanation:

In order to figure this question out, you need to count them up. Count up all the runners that are plotted from 3 miles on. Anything before that is under 3 miles, so it doesn't count.

After counting them up, you will find that there are 7 runners marked who ran 3 miles or more. So your answer is 7 runners.

I hope this helps! Please let me know if you need any more help. Have a great day!

Answer:

y>15/4

Step-by-step explanation:

y/3-3/4>1/2

y/3>1/2+3/4

y/3>2/4+3/4

y/3>5/4

y>5/4*3

y>15/4

Answer:

C (3, 1 )

Step-by-step explanation:

To determine if a point lies on the line, substitute the x- coordinate of the point into the equation and if the value obtained equals the y- coordinate of the point then it lies on the line, otherwise not on line.

A (4 , - 3)

y = - 2(4) + 5 = - 8 + 5 = - 3 ← lies on line

B (- 2, 9 )

y = - 2(- 2) + 5 = 4 + 5 = 9 ← lies on line

C (3, 1 )

y = - 2(3) + 5 = - 6 + 5 = - 1 ≠ 1 ← not on line

D (- 1, 7 )

y = - 2(- 1) + 5 = 2 + 5 = 7 ← lies on line

E (2, 1 ) = - 2(2) + 5 = - 4 + 5 = 1 ← lies on line

Thus (3, 1 ) does not lie on the line → C

Answer:

m = -3

Step-by-step explanation:

−m − 19 = 8m + 8  (Simplify equation)

−9m − 19 = 8  (Subtract 8m from both sides)

−9m = 27  (Add 19 to both sides)

m = -3 (Divide both sides by -9)

Answer:

b^8

Step-by-step explanation:

Answer:

b^8, with m = 8

Step-by-step explanation:

Apply the algebraic rule: (x^a)/(x^b) = x^(a-b)

Note: This rule is true because we can cancel all b factors that occur in both numerator and denominator.

From this rule, we know that (b^10)/(b^2) = b^(10-2)

b^(10-2) can be written b^8
