Answer:

Yes

Step-by-step explanation:

It will be a right-angle triangle if it satisfies the pythagoras theorem

12.5² = 156.25

10² = 100

7.5² = 56.25

Since 12.5² = 10² + 7.5²,

it is a right-angle triangle with 90° at C (because it's opposite the longest side, the hypotenuse)

Neela is making rectangular place mats that are 12 inches wide and 15 inches long. What is the least amount of ribbon that she w

schepotkina [342]

Believe it or not, :), the width of the ribbon needs to be known to get the right answer. If the ribbon had an infinitely small width the ribbon needed would just be the perimeter.

P=2(L+W)

P=2(12+15)

P=54 in

However an infinitely small width is not something that has any practical application. For example, if the width of the ribbon were 1/2 in.

P=2((L+1)+W)

P=2(16+12)

P=56 in So the perimeter increased by 2 in when the ribbon was only 1/2 in wide.

The "infinitely small" width and the perimeter of 54 in is only a decent approximation if the ribbon were a very thin string.

the population of a town grows at the rate of 3 percent each year in 2010, the town had a population of 250000. what is the popu

Ulleksa [173]

Answer:

335,979 people (in Year 2020)

Step-by-step explanation:

Initial Population (Year 2010) = 250,000

Rate of Growth = 3% = 3/100 = 0.03

We want the population of the town in Year 2020 (at this rate). That is 10 years from now.

The formula for compound growth is:

$F=P(1+r)^t$

Where

F is the future value (in year 2020)

P is the present value (250,000)

r is the rate of increase per year (0.03)

t is the time in years (t = 10)

Lets substitute and find the value:

$F=P(1+r)^t\\F=250,000(1+0.03)^{10}\\F=250,000(1.03)^{10}\\F=335979.09$

Rounded, that would be:

335,979 people (in Year 2020)

Which algebraic expression represents the statement: the difference of four times a number and seven.

SIZIF [17.4K]

First, take the written expression apart. Four times a number would be 4n. Then the difference between. That would be a subtract sign. Then finally the seven. The difference between 4n and 7 so:
4n - 7 is your answer.

H(1) =<br> can someone help my brother ?

Fantom [35]

Answer:

h(1) = -2

Step-by-step explanation:

What h(1) is saying is the value of x = 1. We need to find the y-value.

We see from the graph that when x = 1, y = -2.

Pls answer these questions correctly for brainly

FinnZ [79.3K]

40 - 3k + 10k = -10 - 8k - 10

40 + 7k = -10 - 8k - 10

40 + 7k = -8k - 20

40 + 7k - 40 = -8k - 20 - 40

7k = -8k - 60

7k + 8k = -8k - 60 + 8k

15k = -60

15k/15 = -60/15

k = -4
