Answer:
$6.21
Step-by-step explanation:
1 apple = $0.60
3 apples = $1.80 (Multiply 0.60 by 3)
2 bananas = $1.00 (Multiply 0.50 by 2)
1 quart of yoghurt = $4.50
Add the prices up first:
1.80 + 1.00 + 4.50 = $7.30
7.30 off 15% = $6.21
The answer would be -2k -30
Answer:
Area of given figure = 197.48 mi² (Approx.)
Step-by-step explanation:
Note;
Divide given figure into a semi-circle, rectangle, and square
Given:
Radius = 8 mi
Length of rectangle = 11 mi
Width of rectangle = 8 mi
Side of square = 3 mi
Find:
Area of given figure
Computation:
Area of given figure = Area of semi-circle + Area of rectangle + Area of square
Area of given figure = (π/2)(r²) + [L x B] + Side²
Area of given figure = (3.14/2)(8²) + [11 x 8] + 3²
Area of given figure = (1.57)(64) + [88] + 9
Area of given figure = 100.48 + [88] + 9
Area of given figure = 197.48 mi² (Approx.)
Answer:
Answer
Let the sides of triangles are 3x,4x and 5x.
And perimeter of the triangle is 144cm.
So , 3x+4x+5x=144
12x=144
x=12
so, the sides are triangle are 3(12)=36cm, 4(12)=48cm , 5(12)=60cm
so , the longest side is 60 cm.
Area of triangle =
s(s−a)(s−b)(s−c)
here , s=72 and a=36, b=48 c=60
=
72(72−36)(72−48)(72−60)
=
72(36)(24)(12)
=
746496
= 864
So, the area of triangle is 864 cm
2
and the height corresponding to longest side h=
60
2×864
=28.8cm
The answer would be C, y=3x-5
