Answer:

Step-by-step explanation:

To calculate the area of a triangle you will do it like a square or rectangle but you will divide your answer by 2. So...

10 * 6 = 60

60 / 2 = 30

If you have one solution how would you estimate the solution to the tenths place? Explain the process.

Irina18 [472]

To estimate a decimal to the tenths place, you have to round the number from the hundredths place. It all depends on the hundredths place to round a decimal to the tenths place. Let's say that you have a math problem and the answer is 10.46574658, but it says to round to the tenths place. So, you take the first four numbers from the answer, which would be 10.46, go to the tenths and the hundredths. If the number in the hundredths place is greater than 5, round the tenths number up. If the number in the hundredths place is less than 5, it stays the same. So with the number 10.46, the number in the hundredths place is greater than 5, so you round the number in the tenths place up, which becomes 10.5.

A triangle has vertices at f (-7,3),g(2,6) and h(3,5)

Allisa [31]

Answer:

F(-7,3) -> F'(-7,-3)

G(2,6) -> G'(2,-6)

H(3,5) ->H'(3,-5)

Step-by-step explanation:

If you are taking point (a,b) and reflecting it across the x-axis (the horizontal axis), your x value is going to stay the same because you want the point on the same vertical line as (a,b). The y-coordinate is going to be opposite because you want a reflection and the opposite of b will this give you the same distance from the x-axis as b.

So the transformation is this: (a,b) -> (a,-b).

All this means is leave x the same and take the opposite of y.

F(-7,3) -> F'(-7,-3)

G(2,6) -> G'(2,-6)

H(3,5) ->H'(3,-5)

Wayne's deli sells whole sandwiches and half sandwiches. The half sandwiches are in the shape of a triangle because they are cut

Katarina [22]

Answer:

No, those are not the correct measurements.

Step-by-step explanation:

Assuming that 9 will equal the hypotenuse we will use the Pythagorean theorem.

$a^2+b^2=c^2$

a = 5

b = 3

$5^2 + 3^2= 25 + 9 = 34$

Well $9^2= 81$

So...that doesn't quite work out.

Let's change our equation to double check.

$c^2/a^2= b^2$

$9^2/5^2 = b^2\\\\81/25 = 3.25$

Once again, that doesn't work out.

So the final answer is, no. Those are not the correct measurements.
