Help me please me please

Answer:

58 cm^2

Explanation:

there are three rectangles in the shape

the first one on the left has length = 7 cm and width = 3 cm.

so area = l × w

= 7×3

=21 cm^2

the one in the middle has length = 4 cm and width = (7- 3) => 4cm

so area = 4 × 4

= 16 cm^2

the last one to the right is identical to the first, so area = 21 cm^2

The combined area = 21 + 16 + 21

= 58 cm^2

Answer:

$\frac{2^{5} }{6^{5} } =2^{5} 6^{-6}$

$=2^5\times (2^{-5} 3^{-5} )$

$=2^{5-5} 3^{-5}$

$=2^{0} 3^{-5}$

$=3^{-5}$

A furnace delivers 8.0 × 104 btu per hour. how many kilocalories per hour is this?

vazorg [7]

For this case the first thing you should know is the following unit conversion.
1 BTU = 0.25 Kilocalories
We then have the following numerical value:
$8.0 * 10 ^ 4 \frac{BTU}{h}$
Applying the conversion of units we have:
$8.0 * 10 ^ 4 \frac{BTU}{h} * 0.25 \frac{Kcal}{BTU}$
Canceling units we have:
$20000 \frac{Kcal}{h}$
Answer:
This is 20000 kilocalories per hour
$20000 \frac{Kcal}{h}$

a person invest $1,700 in an account that earns 3.97% annual interest. find when the value of the investment reaches $3,200

olga_2 [115]

Answer:

16 1/4 years

Step-by-step explanation:

Assuming interest is compounded annually, the account balance (A) after t years will be ...

A = P(1 +r)^t

3200 = 1700·1.0397^t

log(3200) = log(1700) +t·log(1.0397)

t = (log(3200) -log(1700))/log(1.0397) ≈ 16.247

The account will reach a balance of $3200 after about 16 1/4 years.

You may be asked to round your answer to the nearest integer or tenth. We leave that exercise to the student.

What is the midpoint of the coordinate F( -2, 4) and G(6, 1)

Marrrta [24]

Answer:

$\huge\boxed{\left(2; 2\dfrac{1}{2}\right)}$

Step-by-step explanation:

$\text{The formula of a midpoint:}\\\\M\left(\dfrac{x_1+x_2}{2};\ \dfrac{y_1+y_2}{2}\right)\\\\\text{We have the points}\ F(-2,\ 4),\ G(6,\ 1).\\\\\text{Substitute:}\\\\M_{FG}\left(\dfrac{-2+6}{2};\ \dfrac{4+1}{2}\right)\to M_{FG}\left(\dfrac{4}{2};\ \dfrac{5}{2}\right)\to M_{FG}\left(2; 2\dfrac{1}{2}\right)$
