Step-by-step explanation:

Area of rectangle = width × length

= 10 × 15 = 150 cm²

The height of triangle = 14 - 10 = 4 cm

Area of triangle = 1/2 × base × perpendicular height

= 1/2 × 5 × 4

= 10 cm²

Area of this figure = area of rectangle + area of triangle

= 150 + 10 = 160 cm²

A flower bed has the shape of a rectangle 5 yards long and 4 yards wide. What is its area in square feet?

aalyn [17]

To find the area, use A= bh (base x height), or A = lw (length x width)

There are 3 feet in 1 yard

3 x 5 = 15
4 x 3 = 12

15 x 12 = 180

The flower bed is 180 ft²

hope this helps

A population of 200 animals has a growth rate of 1.03% each year. at this growth rate, the function f(x)=200(1.03)^x gives the p

Y_Kistochka [10]

For this case, the first thing we should do is use the following equation:
f (x) = 200 (1.03) ^ x
We substitute f (x) = 300:
300 = 200 (1.03) ^ x
We clear the value of x:
log1.03 (300/200) = log1.03 ((1.03) ^ x)
x = log1.03 (300/200)
x = 13.72
Answer:
the population will first reach 300 in about 13.72 years.

Jose left the White House and drove toward the recycling plant at an average speed of 40 km/h. Rob left some time later driving

Aleks04 [339]

Let $x$ represent Jose's drived distance and $y$ represent Rob's.
So what you need to do is to solve the equation:
$40x=48*5$
$40x=240$
$x=240/40=6$

So Jose drove for 6 hours before Rob caught him.
