The area of that figure is 2453.25 square feet

First, you would need to find the area of the rectangle

(L)(W)
(70)(30)
2100

Then since it is only a semi circle, the formula is pi*r^2/2

You find the area of a full circle first

(3.14)(15^2)
(3.14)(225)
706.5

Then you divide that by 2 since it’s only half a circle

706.5/2 = 353.25

Finally you add that by the area of the rectangle

2100 + 353.25 = 2453.25 square feet

Jack has two jobs

The first one, he works at a gas station where he earns $11/hr, he works for 8 hours in a week

= 11×8

= 88

The second one he earns $120/week for walking dogs

Therefore the total money Jack earns in a week can be calculated as follows

= 120+88

= 208

The length of a rectangle is 1 foot more than twice the width the perimeter is 44 feet find the dimensions of the rectangle

Annette [7]

The length of rectangle is 15 feet and width is 7 feet.

Step-by-step explanation:

Given,

Width of rectangle = w

Length of rectangle = 2w+1

Perimeter = 44 feet

Perimeter = 2(Length+Width)

$Perimeter=2(2w+1+w)\\44=2(3w+1)\\44=6w+2\\44-2=6w\\42=6w\\6w=42$

Dividing both sides by 6

$\frac{6w}{6}=\frac{42}{6}\\w=7$

The width of rectangle is 7 feet.

Length of rectangle = 2(7)+1 = 14+1 = 15 feet

The length of rectangle is 15 feet and width is 7 feet.

Is 3x-5+y=2y-4 linear if so write the equation in standard form and give the values of A B and C

ruslelena [56]

Equation in standard form:
Ax+By=C

We have:
3x-5+y=2y-4
3x+y-2y=-4+5
3x-y=1

Therefore:
A=3
B=-1
C=1

Answer: the equation in standard form would be: 3x-y=1; and the values of A, B and C would be: A=3; B=-1 and C=1.

The base of an isosceles triangle is a fourth as long as the two equal sides. write the perimeter of the triangle as a function

jeka57 [31]

Set the length of the base as x, the two equal sides are then 4x each, so the perimeter is x+4x+4x=9x
