Mathematics
1 answer:
Slav-nsk [51]4 years ago
4 0

Answer:

5 units

Step-by-step explanation:

By Pythagoras theorem:

(hypotenuse)^2 = a^2+ b^2\\\therefore hypotenuse = \sqrt{a^2+ b^2} \\\therefore hypotenuse = \sqrt{3^2+ 4^2} \\\therefore hypotenuse = \sqrt{9+ 16} \\\therefore hypotenuse = \sqrt{25} \\\therefore hypotenuse = 5\: units

How do I find the value of y?
Genrish500 [490]

Answer:

y = 27

Step-by-step explanation:

line segment BA and CD are congruent, turn them into an equation

3y - 59 = y - 5

subtract 1y from both sides, you get 2y - 59 = -5

then, add 59 to both sides and the equation is now 2y = 54

divide each side by 2 and you get the value of y (y = 27)

A) Work out (5 x 10^3)x(9 x 10^7)<br> Give your answer in standard form.
Marina86 [1]

Answer:

45000000000

Step-by-step explanation:

when multiplying exponents, you multiply base numbers with no exponent (9 and five in this case) and numbers with exponents (10 in this case). 9 X 5 is 45 and 10 to the power of 7 times 10 to the power of 2 is 10 to the power of 9 or 1000000000. 45 X 1000000000 is 45000000000.

A cube has volume 1200 cubic inches. Write the edge length of the cube as a power.
frozen [14]
The volume of a cube is an edge length cubed, so an edge length would be the volume to the 1/3 power. Therefore, the edge length of this 1200 cm³ cube can be written as 1200^{ \frac{1}{3} } cm. This also equals 2∛150 cm and is approximately 10.627 cm.
