Two circles with radii 3.5 cm and 2.5 cm touch each other internally. Find the distance between their centres.

Answer:

1000

Step-by-step explanation:

The population of the suburb after each decade d is given by the equation as follows :

[tex]P=4000\times 2^d[/tex]

We need to evaluate the expression for d = -2.

Put d = -2 in the above equation. So,

[tex]P=4000\times 2^{-2}\\\\=4000\times \dfrac{1}{2^2}\\\\=4000\times \dfrac{1}{4}\\\\=1000[/tex]

So, if d = -2, then the population of the suburb is equal to 1000.

Answer:

100 red bricks

Step-by-step explanation:

Let's say red bricks is equal to 5x

Gray bricks is equal to 2x

We have an equation

2x + 5x = 140

= 7x = 140

Divide through by 7 to get the value of x

X = 140/7

X = 20

Red bricks = 5(x)

= 5(20)

= 100

Gray bricks = 2(x)

= 2(20)

= 40

Therefore in conclusion the number of red bricks is 100.

Answer:

Eliminate y by adding equations (1) and (3) because the coefficients on y are opposites. Then eliminate y by multiplying equation (1) by 2 and adding it to equation (2).

Eliminate z by subtracting equations (1) and (2) because the coefficients are the same. Then eliminate z by multiplying equation (3) by 2 and adding it to equation (1).

Step-by-step explanation:

The variables have to be the same in both equations in the 2 × 2 system.

Answer:

?????????????????????????

Step-by-step explanation:

The solution is, final answer is 288 square inches.

Area is the measure of a region's size on a surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of a three-dimensional object.

here, we have,

Given that Area of the square mirror = 256 square inches

We know that area of square is given by formula

Area = x^2, where x is the side of the square

plug the given value

256=x^2

take square root

16=x

Hence width of the square is 16 inches.

Given that a rectangular mirror has a width the same as the square mirrors width.

Then width of the rectangle = 16 inches

Length of the rectangle = 16+2 = 18 inches

Area of rectangle = Length * width = 16*18 = 288

Hence final answer is 288 square inches.

Step-by-step explanation:

Given

Shape: Isosceles Triangle

[tex]Perimeter=24\ in[/tex]

[tex]Side = 4\ in[/tex]

Required

Find the length of the other two sides

Represent the other sides with x.

Since it is an isosceles triangle, 2 sides are equal.

So, we have:

[tex]x + x + 4 = 24[/tex]

[tex]2x + 4 = 24[/tex]

Collect Like Terms

[tex]2x = 24-4[/tex]

[tex]2x = 20[/tex]

Divide both sides by 2

[tex]\frac{2x}{2} = \frac{20}{2}[/tex]

[tex]x = \frac{20}{2}[/tex]

[tex]x = 10[/tex]

The other sides are 10in each
