<em>Answer:</em>

<em>A(a) = 24 cm²</em>

<em>A(b) = 40.04 cm² ≈ 40 cm²</em>

<em>Step-by-step explanation:</em>

<em>Hi there ! </em>

<em>area formula (rectangle)</em>

<em>A = l × w</em>

<em>A(a) = 8cm × 3cm = 24 cm</em>

<em>A(b) = 5.2cm × 7.7cm = 40.04 cm² ≈ 40 cm²</em>

Find the sum of this infinite geometric series where a1=0.3 and r=0.55

Lisa [10]

Hello, Marymack!

We know that in a geometric sequence defined by $\mathsf{a_1}$ and $\mathsf{r}$ , the sum can be calculated the following way:

$\mathsf{S_n = \dfrac{a_1}{1-r}}\\ \\ \\ \\ \mathsf{S_n = \dfrac{0.3}{1-0.55}}\\ \\ \\ \mathsf{S_n = \dfrac{0.3}{0.45}}\\ \\ \\ \boxed{\mathsf{S_n = \dfrac{2}{3}=0.666...}}$

Use the midpoint formula to find the midpoint between H(3, 9) and J(9, -2).

TiliK225 [7]

Hello!

The midpoint formula is basically an average of x and y.

It is also written as: $(\frac{x_{1}+x_{2}} {2},\frac{y_{1}+ y_{2}} {2})$ .

With the formula above, we can substitute the given points into the equation, and simplify.

$(\frac{3 +9}{2}, \frac{9+(-2)}{2}) = (\frac{12}{2}, \frac{7}{2}) = (6, 3.5)$

Therefore, the midpoint between points H and J is choice D, (6, 3.5).

What value makes the equation 11-3x=-7 true?

german

X = 6

11-3x=-7
Subtract 11 from both sides.

-3x = -18
Divide -3 on both sides.

X = 6

A 12-team soccer league has $7,260 to award as prize money. the team that finishes in last place will receive $220, and the priz

Anestetic [448]

Answer: $ 990

Step-by-step explanation:

Since, the total number players, n = 12,

The least amount got by one team, a= $ 220

Let there is a successive difference of d,

Thus, the given situation forms an AP,

In which sum of the AP, $S_n= \frac{12}{2}[2\times 220 + (12-1)d]$

But, According to the question,

$S_n = $ 7260$

⇒ $\frac{12}{2}[2\times 220 + (12-1)d]=7260$

$6[440 + (11)d]=7260$

$440 + 11 d=1210$

$11 d =770$

$d = 70$

Thus, the successive difference, d = $ 70

⇒ The amount of first price,

$a_{12} = 220 + (12-1)\times 70 = 220 + 770 = \$ 990$
