Please help with area of right triangles!

Mathematics
1 answer:
ipn [44]4 years ago
7 0

Answer:

Step-by-step explanation:

Since the side length of one square in the grid is 1 unit, we know that the side lengths of the right triangle are 2 and 7 units.

The area of a triangle is A=1/2*b*h

A=1/2*2*7

A=1*7

A=7

So the area of the triangle is 7 square units

2 Select the correct answer. What is the inverse of function ? F(x)=10/9x+11 A.f-1(x)=9x-99/10 B.f-1(x)=9/10x+11 C.f-1(x)=9x+11/
Lilit [14]

Consider f(x)=y.

\begin{gathered} f(x)=y \\ x=f^{-1}(y) \end{gathered}

Simplify the equation f(x)=y to obtain the value of x in terms of y.

\begin{gathered} f(x)=y \\ \frac{10}{9}x+11=y \\ \frac{10}{9}x=y-11 \\ 10x=9y-99 \\ x=\frac{9y-99}{10} \end{gathered}

So inverse of function is,

f^{-1}(x)=\frac{9y-99}{10}

Correct nswer is A part.

Hey cutie you wanna help? I need the answer urgently
BigorU [14]

Answer/Step-by-step explanation:

4(x - 2)= 100 and 2(x - 2) = 50.

We can determine that in both equation x equals 27. But, why is the second one half as much as the first problem? This is because the second problem is being multiplied with a number half as large as the first. Since 27 - 2 = 25 and 25 x 4 = 100 and 25 x 2 = 50 these problems hold up to their function.

If x = 27:

<u>4(x - 2) = 100</u>

27 - 2 = 25

25 x 4 = 100

<u>2(x - 2) = 50</u>

27 - 2 = 25

25 x 2 = 50

Ben is 140cm tall. Mike is 1090mm tall. Who is taller? How much taller?
DIA [1.3K]
1cm = 10cm
140cm=1400mm So Ben taller

Difference is bigger minus smaller
1400-1090=310mm :)
