Express the area of this triangle as monomial.

gladu [14]

The formula of an area of a triangle:

$A=\dfrac{1}{2}bh$

b - base

h - height

We have b = 8x and h = 7x. Substitute:

$A=\dfrac{1}{2}(8x)(7x)=(4x)(7x)=28x^2$

There are 2 boys for every 3 girls. Today 5 new boys were added making the number of girls and boys the same. How many boys and

Anna11 [10]

Answer:

10 boys, 15 girls

Step-by-step explanation:

Original ratio: 2 boys/3 girls

let x be the scale factor of the ratio

2x plus 5 boys over 3x girls = 1 (because the # of boys/girls are the same)-------> 2x+5/3x = 1

Simplify: 2x+5=3x

Simplify: 5=x

plug x back into the original ratio: 10/15

Check: 10/15 = 2/3

10 boys + 5 boys = 15, 15/15 = 1

Referring to triangle ABC, find the area of the triangle.

kondaur [170]

Answer:

$Area = 337$

Step-by-step explanation:

Given

$a = 42.5$

$c = 35.5$

$B = 153.5^\circ$

Required

Area of triangle

This is calculated as:

$Area = 0.5 *a* c * \sin(B)$

This gives:

$Area = 0.5 *42.5* 35.5 * \sin(153.5)$

$Area = 0.5 *42.5* 35.5 * 0.4462$

$Area = 336.602125$

$Area = 337$ --- approximated
