£360 is shared between Abby, ben, chloe and denesh. the ratio of the amount abby gets to the amount that ben gets is 2:7. chloe

Gwar [14]

Answer:

$210$ £

Step-by-step explanation:

Let amount that abby gets $=x$

Given that $\frac{Amount\ of\ abby}{Amount\ of\ Ben} =\frac{2}{7}$

$Amount\ of\ ben=\frac{7}{2}\times Amount\ of\ abby\\ =\frac{7}{2}\ x$

Amount of chole + amount of Danesh $=1.5\times$ of abby

$=1.5 \ x$

$x +\frac{7}{2} \ x + 1.5 \ x =360\\\\6x=360\\\\x=\frac{360}{6}\\\\x=60$

$Amount\ of\ Ben =\frac{7}{2}\ x = \frac{7}{2} \times 60\\\\=7\times 30\\\\=210$

Find the area of the shaded region

PIT_PIT [208]

Answer:

Area of the shaded region= $500inch^2$

Step-by-step explanation:

Area of the shaded region= Area of the triangle- Area of the rectangle

Dimensions of the triangle:

Base= 40 inch

Height= 40 inch

Area of a triangle= $\frac{1}{2}*Base*Height$

$=\frac{1}{2}*40*40\\\\ =\frac{1}{2} *1600\\\\=800 inch^2$

Area of the rectangle= Length*Width

Length=30 inch

Width=10 inch

Area:

$= 30*10\\\\=300 inch^2$

Area of the shaded region= $800-300= 500 inch^2$

Evaluate la+b-cl, given a=5, b=_3, and c =-2

zloy xaker [14]

Answer:

Step-by-step explanation:

Assuming you meant to type b= -3, you would plug in 5 + -3 + -2 to equal 0. The answer would then be 0.

If b was supposed to be +3, then it would be absolute value of 5 + 3 + -2 to equal 6.

Yesterday, 12 kids played Among Us and 8 kids did

marysya [2.9K]

Answer:

60%

Step-by-step explanation:

12 kids played. 8 didn't play. That means there is a total of 20 students.

The fraction would be 12/20.

To make it into a percent, divide 100 by the denominator (20) and multiply it by the numerator (12)

100 divided by 20 is 5

12 x 5 = 60
