You would add 37 and 11 which equals 48.
So Jacob counted 48 ants all together.

Rectangleville's limits form a perfectly rectangular shape whose length is 202020 kilometers and width is 121212 kilometers. It

kotykmax [81]

Answer:

76,800

Step-by-step explanation:

Given the following :

Length = 20 kilometers

Width = 12 kilometers

Population density = 320 people per sq km

Population =?

Recall:

Area of rectangle = Length × width

Therefore,

Area of Rectangleville = 20 km × 12 km = 240km^2

Population is related to population density and Area by the formula ;

Population density = population ÷ Area

Therefore,

Population = population density × Area

Population = 320 × 240 = 76,800

Therefore, the population of Rectangleville is 76,800 people

Please help on this math question!!

katrin2010 [14]

Answer:

x = 49

Step-by-step explanation:

The third side of the largest of the inner triangles:

= $\sqrt{(7\sqrt{(33)^{2} }- (33)^{2}$

= $\sqrt{528} =\sqrt{(16)(33)} =4\sqrt{33}$

The side that continues next to 33: x -33

Applying similarity property on right triangles:

$\frac{33}{4\sqrt{33} } =\frac{4\sqrt{33} }{x-33}$

$(33)(x-33)=(4\sqrt{33} )^{2}$

$33x-1089=528$

$33x=528+1089$

$x=\frac{528+1089}{33} =49$

Hope this helps

Each face of a small cube has a surface area of 0.25 square meters. A larger cube has edges that are six times as long as the ed

Dennis_Churaev [7]

Answer:

D. 27 meters cubed

Step-by-step explanation:

The first step is to find the edge length of the small cube. The square root of 0.25 is 0.5, meaning that a larger cube with six times the edge length will have an edge of 0.5*6=3 meters. 3 meters cubed is 27 cubic meters, or option D. Hope this helps!

The water reaches a max height when the horizontal distance from the firefighter to the building is approximately __m. Round to

elena-s [515]

The horizontal distance from the firefighter at which the maximum height of water occurs is 10.83m

<u>Explanation:</u>

Given:

h(x) = -0.026x² + 0.563x + 3

where,

h(x) is the height of the water

Initial speed, u = 14m/s

angle, θ = 30°

(a)

Horizontal distance = ?

h(x) = ax² + bx + c

the vertex is found at x = -b/2a

where,

x = distance to the maximum height

As compared to the equation given:

a = -0.026

b = 0.563

Thus,

$x = \frac{-0.563}{2 X -0.026} \\\\x = \frac{0.563}{0.052}\\ \\x = 10.83m$

Therefore, horizontal distance from the firefighter at which the maximum height of water occurs is 10.83m
