Ainat [17]3 years ago
8 0

Answer:

Solution given;

slant height[l]=32km

side of equilateral triangle (a)=14km

now

total surface area of triangular pyramid =

area of base triangle +3 area of traingular faces

=√3/4 a²+3×½×{b×l}

=√3/4 14²+3/2×{14×32}

=756.87=757 km² is a required surface area.

. The temperature on Monday was −5∘C . By Tuesday the temperature rose to −2∘C. Find the change in temperature.
Alekssandra [29.7K]

Answer: 3^{\circ}C

Step-by-step explanation:

Given

The temperature on Monday was -5^{\circ}C

By Tuesday, it becomes -2^{\circ}C

Change in temperature is the difference between the two temperatures.

\Rightarrow \Delta T=-2-(-5)\\\Rightarrow \Delta T=-2+5\\\Rightarrow \Delta T=3^{\circ}C

Therefore, the change in temperature is 3^{\circ}C.

The upper-left coordinates on a rectangle are (-5, 6)(−5,6)left parenthesis, minus, 5, comma, 6, right parenthesis, and the uppe
sammy [17]

Answer:

Step-by-step explanation:

The question is incomplete. Here is the complete question.

The upper-left coordinates on a rectangle are (−5,6) and the upper-right coordinates are (−2,6). The rectangle has a perimeter of 16units. Draw the rectangle on the coordinate plane below.

If the coordinates of the top of the triangle (breadth) is  (−5,6) and  (−2,6), we can calculate the breadth of the rectangle by taking the difference between the two points using the formula:

D = √(y₂-y₁)²+(x₂-x₁)²

Given x₁ = -5, y₁= 6, x₂ = -2 and y₂ = 6

D = √(6-6)²+(-2-(-5))²

D = √0²+3²

D = √9

D = 3 units

Breadth = 3 units

Given the Perimeter to be 16 units and the formula for calculating the perimeter of rectangle t be P = 2(L+B), we can get the length of the rectangle.

16 = 2(3+L)

16 = 6+2L

16-6 = 2L

2L = 10

L = 10/2

L = 5 units.

<em>Hence the length of the rectangle is 5 units and the breadth is 3 units. Find the diagram in the attachment.</em>
