Answer:

8) 42 in²

9) 33 cm²

10) 112 yd²

Step-by-step explanation:

8) The area is given by the formula ...

A = 1/2(b1 +b2)h

A = (1/2)(9 in +5 in)(6 in) = 42 in²

9) The area is half the product of the lengths of the diagonals.*

A = 1/2(d1)(d2)

A = 1/2(6 cm)(11 cm) = 33 cm²

10) As in the previous problem, ...

A = 1/2(14 yd)(16 yd) = 112 yd²

_____

* This formula works for any quadrilateral with perpendicular diagonals.

Answer: 6 hours

Step-by-step explanation:

You would first start by making 1 3/5 into a mixed fraction. Getting 8/5. Then you’d divide that by 3/4 and get 6/5. Which then you’d multiply it by 5 and get 6 hours.

Which strategy should be used to correctly solve this problem?

hammer [34]

B, make a table of possible values

the best way to do it is actually not listed
to have max area with minimu perimiter, try to get the sides as close measure to each other as possible

I would pick B though

Consider functions f and g.1 + 12f(1) = 12 + 4. – 12for * # 2 and 7 -64.2 – 16. + 1641 +48for a # -12 Which expression is equal

Given the following functions below,

$\begin{gathered} f(x)=\frac{x+12}{x^2+4x-12}\text{ and} \\ g(x)=\frac{4x^2-16x+16}{4x+48} \end{gathered}$

Factorising the denominators of both functions,

Factorising the denominator of f(x),

$\begin{gathered} f(x)=\frac{x+12}{x^2+4x-12}=\frac{x+12}{x^2+6x-2x-12}=\frac{x+12}{x(x+6)-2(x+6)}=\frac{x+12}{(x-2)(x+6)} \\ f(x)=\frac{x+12}{(x-2)(x+6)} \end{gathered}$

Factorising the denominator of g(x),

$\begin{gathered} g(x)=\frac{4x^2-16x+16}{4x+48}=\frac{4(x^2-4x+4)}{4(x+12)} \\ \text{Cancel out 4 from both numerator and denominator} \\ g(x)=\frac{x^2-4x+4}{x+12}=\frac{x^2-2x-2x+4}{x+12}=\frac{x(x-2)-2(x-2)}{x+12}=\frac{(x-2)^2}{x+12} \\ g(x)=\frac{(x-2)^2}{x+12} \end{gathered}$

Multiplying both functions,

$undefined$

Answer:

number 21: 5 ten thousands, 7 hundreds, 7 tens and 7 ones

Step-by-step explanation:

7 tens = 70

7 ones = 7

which equals 77, if the number is 50,777, you can see the last two digits in the tens and ones place are 7 and 7.
