What is the area of the triangle?

Mathematics
1 answer:
densk [106]3 years ago
5 0

Answer:

10\:\mathrm{units^2}

Step-by-step explanation:

The area of a triangle can be given as \frac{1}{2}\cdot b \cdot h. Notice that a base of the triangle is given as 4 units, and the height is marked as 5 units. We know that the segment marked as 5 units is the height of the triangle because it forms a 90^{\circ} with the segment marked as 4 units and meets a vertex of the triangle.

Therefore, the area of the triangle is:

\frac{1}{2}\cdot 4 \cdot 5 = \fbox{$10$}.

icang [17]

Let x = number of white marbles and y = number of yellow marbles.

x + y = 57 => x = 57 - y

Also, x = 3 + 5y

Substitute x for y.

57 - y = 3 + 5y => 57 - 3 = 54 = 6y

So, y = 9

Since x (our answer) = 3 + 5 (9),

x = 48.

Check: 48 + 9 = 57 total

A crystallographer measures the horizontal spacing between molecules in a crystal. The spacing is 14.8 nm . What is the total wi
IrinaK [193]
Answer: 1539.2nm

The space between molecule is going as X-1 function. That mean 1 molecule doesn't have space, 2 molecules have 1 space, 3 molecules have 2 space. Then 105 molecules will be will have 104 space.
Each space is 14.8nm, the total  distance would be: 104 space x 14.8 nm/space= 1539.2nm

Y-80x=65 in function notation
kolezko [41]

Answer:f(x) = 80x + 65f


Step-by-step explanation:

Since x = days and y = total rent, you've been given two points on your function: (5, 465) and (7, 625). We'll find the slope using those two points:

(625 - 465) / (7 - 5) = 160/2 = 80

Then, use m = 80 and one of the points to write the equation of your line in point-slope form:

y - y1 = m(x - x1)

y - 465 = 80(x - 5)

Convert that to standard form:

y = 80(x - 5) + 465

y = 80x - 400 + 465

y = 80x + 65

y - 80x = 65

In function notation, that's:

f(x) = 80x + 65

Witch is greater 100in or 3yd 1ft
pychu [463]
First you need to convert then to the same units. So 3yd 1ft would be equal to 10 ft. Then you need to convert the feet to inches. 10ft x 12 is equal to 120 inches.

120 inches is greater that 100 inches.
