3 is in the hundreds place, therefore 3 hundreds or 300
Answer:
By hypotenuse - side test (HL) the two triangles are congruent.
Step-by-step explanation:
In ∆ABC and ∆DCB
i) angleABC = angleDCB.....(each 90°)
ii) BC = BC .....( common side)
iii) AC = DB.....(given)
therefore by hypo-side test ∆ABC congruent ∆DCB
Answer:
14
Step-by-step explanation:
If he had 14 then he gave away 6, he'd have 8. 8 plus 4 is 12. He had 14 before giving any away.
17+4=21
21 divided by 3= 7
17 dollars for tickets
21-4=17
so your answer is 21 he has to sweep the floor 21 times to get tickets
Answer:
76
Step-by-step explanation:
recall that for a quadratic equation in the form
ax² + bx + c = 0, the discriminant is given by
discriminant, D = b²- 4ac
we are given the following:
-6x² + 2x + 3 = 0,
comparing this with the general equation above, it is clear that,
a = -6, b = 2 and c = 3,
substituting these into our equation for discriminant:
D = b²- 4ac
= 2² - 4(-6)(3)
= 4 + 72
= 76
