Figure T is similar to figure W which answer is closest to the length of side XY

1 answer:

As they are similar triangles, one is simply going to be bigger than the other, meaning that if triangle T’s side QS is = 9 and triangle W’s corresponding side ZX is =6.5. When dividing 9 by 6.5, it is obvious that triangle W is 0.72 smaller than triangle T. All you then have to do to calculate length of side XY is times side QR on triangle T -cause it’s the corresponding side of these two triangles- by 0.72, and you’ll have your answer of XY= 8.125 :)

Answer:

1. Anne = 21 Bobby=35, 450, 70+40+30=140

Step-by-step explanation:

1 21÷3=7
7×5=35

7-2=250
5=250
1=50
2×50+7×50=100+350=450
450

we can see that it's multiplied by 10, so 70+40+30=140

the perimeter of am equilateral triangle is 7 inches more than perimeter of a square and the side of the triangle is 5 inches mo

Dmitry [639]

Let $t$ be the side of the triangle and $s$ be the side of the square.

Let $P_t$ be the perimeter of the triangle and $P_s$ be the perimeter of the square.

We have the following relationship:

$\begin{cases}P_t = P_s+7\\t=s+5\\P_t = 3t\\P_s=4s\end{cases} \implies \begin{cases}3t=4s+7\\t=s+5\end{cases} \implies 3(s+5)=4s+7 \implies s=8$

Which finally implies

$t=s+5=13$

-BARSIC- [3]

(-2,-4)

Cramer's rule

10x - 4y = -4

-3x + 7y = -22

Main determinant : 58

Determinant of <em>x</em> : -116

Determinant of <em>y</em> : -232

So, (-2,-4)

A cube had a volume of 1/512 cubic meter. What is the length of each side of the cube using the formula "volume=Length×Width×Hig

MrRa [10]

Answer:

The length of each side of the cube is $\frac{1}{8}\ m$

Step-by-step explanation:

we know that

The volume of a cube is equal to

$V=LWH$

but remember that in a cube

Length, width and height have the same value

so

Let

b-----> the length side of the cube

$L=W=H=b$

substitute in the formula

$V=(b)(b)(b)=b^{3}$

In this problem we have

$V=\frac{1}{512}\ m^{3}$

substitute and solve for b

$b^{3}=\frac{1}{512}$

$b=\sqrt[3]{\frac{1}{512}}\\ \\b=\frac{1}{8}\ m$

therefore

The length of each side of the cube is $\frac{1}{8}\ m$
