Mathematics
1 answer:
Ket [755]3 years ago
5 0

Answer:

x = -10

y = 13

Step-by-step explanation:

-3x + 2y = 56

-5x - 2y = 24

__________ +

-8x____ = 80

x______= 80/-8

______x = -10

-3x + 2y = 56

-3(-10) + 2y = 56

30 + 2y = 56

2y = 56 - 30

2y = 26

y = 26/2

y = 13

Priya drew a circle whose area is 25 cm. Dan drew a circle whose diameter is 4 times the radius of Priya's circle. How many time
Vitek1552 [10]

Answer:

400

Step-by-step explanation:

first work out the radius of priya's circle with the equation a = \pi r^{2}

25 = \pi r^{2}

\frac{25}{\pi } = r^{2}

r = \sqrt{\frac{25}{\pi } }

we know the diameter of a circle is 2 times the radius so the diameter of priya's circle is 2x\sqrt{\frac{25}{\pi } }

this means that if the diameter of dan's circle is 4 times bigger it must be

8x\sqrt{\frac{25}{\pi } }

to find the radius of dan's circle we divide the diameter by to 2 to give

4x \sqrt{\frac{25}{\pi } }

then use the a=\pi r^{2} equation again

a= (4 \sqrt{\frac{25}{\pi } })^{2} \pi

which equals 400

hope that helped

The graph of a quadratic f(x) intersects the x-axis at –15 and 9. What is a possible
Orlov [11]

the point that the function intercepts the x axis are the zeros of the function, where the products set equal to zero give you the x coordinate in which it intercepts.

x=-15 and x=9

set both equal to 0

x+15 and x-9

These are your two products

(x+15)(x-9)

or

x^2+6x-135

1. A metal cylinder is measured to have a length of 5.00 cm and a diameter of 1.26 cm. Compute the volume of the cylinder in cm3
vichka [17]

Answer:

vol = 6.23 cm3

Step-by-step explanation:

dia = 1.26 cm

length = 5.00 cm

vol = area * L

vol = (pi * 1.26² / 4 ) * 5

vol = 6.23 cm3
