Answer:

Step-by-step explanation:

x + 18 + - 15 = 100

x + (18 - 15) = 100

x + 3 = 100

x = 100 - 3

x = 97

46.

Marizza181 [45]

Answer:

46. 10+10+6+6=32

47. 10×6=60

Step-by-step explanation:

46. the formula the perimeter is length plus width, is this case 10+6. but that would only be 2 sides so you have to times that by 2... (10+6)×2

47. area equals length times width so in this case 10×6=60

Austin is fertilizing his garden. The garden is in the shape of a rectangle. Its length is 14 feet and its width is 11 feet. Sup

KATRIN_1 [288]

First you need to find the area, the formula is A=LxW, multiply 14 by 11, that’s the area. If one back covers 22 ft we need to find how many 22s are in 154, to do that you divide. Make sense?

A vessel sails 41 miles S 35° E. How far south has it sailed?

const2013 [10]

Option A: The vessel has sailed 34 miles South

Explanation:

Given that the vessel sails 41 miles S 35° E.

We need to determine the how far south the vessel has sailed.

Let us use the Pythagorean theorem to find the distance of the vessel has sailed.

Thus, we have,

$cos \ \theta=\frac{adj}{hyp}$

Substituting $\theta=35^{\circ}$ , $adj=x$ and $hyp=41$

Hence, we get,

$cos \ 35=\frac{x}{41}$

Simplifying, we have,

$0.82=\frac{x}{41}$

Multiplying both sides by 41, we have,

$33.62=x$

Rounding off to the nearest integer, we have,

$34=x$

Thus, the vessel has sailed 34 miles South.

Therefore, Option B is the correct answer.

What is the area of the figure below? Use 3.14 for pi. Round your answer to the nearest hundredth.

sammy [17]

Answer:

area of the figure ≈61.23 cm² to the nearest hundredth

Step-by-step explanation:

To find the area of the figure, we will follow the steps below;

Looking at the figure, we will see that the figure comprises of both semi-circle and a parallelogram

area of figure = area of semicircle + area of parallelogram

first, we will find the area of the semi-circle

area of a semi-circle = πr² /2

from the diagram given, diameter = 7cm

but diameter = 2r, this implies that radius r = d/2, hence radius r = 7/2 = 3.5 cm

π = 3.14

Lets insert the values into the formula

area of a semi-circle = πr² /2

=3.14×3.5² /2

=3.14×12.25 /2

=19.2325 cm²

Area of a parallelogram = b×h

where b = base and h = height

from the figure given, base b = 7cm and height h = 6 cm

Lets insert the values into the formula

Area of a parallelogram = b×h

= 7×6

=42 cm²

area of the figure = area of semicircle + area of parallelogram

=19.2325 cm² + 42 cm²

=61.2325 cm²

≈61.23 cm² to the nearest hundredth

area of the figure ≈61.23 cm² to the nearest hundredth
