Answer:  x= 1 and y =1

Step-by-step explanation:

The given system of equation is :

5x - 4y = 1-------(1)\\\\2x + 3y = 5----------(2)

Multiply 2 to equation (1) and 5 to equation (2) , we get

10x-8y=2-------------(3)

10x+15y=25-----------(4)

Subtracting equation (3) from equation (4), we get

15y+8y=23\\\\\Rightarrow\ 23y=23\\\\\Rightarrow\ y=1

Substitute, the value of y in (1), we get

5x - 4(1)= 1\\\\\Rightarrow\ 5x=1+4=5\\\\\Rightarrow\ x=\dfrac{5}{5}=1

Hence, the solution of the given system is (x,y) = (1,1)

Item 16 A scale drawing of a triangular sign has a scale factor of 1:8. Which statements are true? The ratio of the area of the
Step2247 [10]

Answer:

The correct option is;

The ratio of the area of the scale drawing to the area of the sign is equal to the square of the scale factor

Step-by-step explanation:

Here we have a scale factor of 1:8

Therefore area of drawing = 1/2×base, b×height, h = 1/2×b×h

Hence, the area of the triangular sin will be given by 1/2×8×b×8×h

Area of triangular sign = 64 × 1/2×b×h

Hence the ratio of the area of the scale drawing to the area of the triangular sign is equal to the square of the scale factor.

Find the volume of a cone of radius 49cm and height 10cm​
den301095 [7]

Answer:

<h2> 25154.34{cm}^{3}</h2>

Step-by-step explanation:

Given,

Radius ( r ) = 49 cm

Height (h) = 10 cm

Volume of cone=?

Now,

Applying the formula to find the volume of cone:

\pi \:  {r}^{2}  \frac{h}{3}

Plugging the values,

\frac{22}{7}  \times  {49}^{2}  \times  \frac{10}{3}

\frac{22}{7} \times 2401 \times  \frac{10}{3}

Calculate

25153.34  \:  {cm}^{3}

Hope this helps...

Good luck on your assignment..
