1.4 because you divide 7.45 by 5.51 and you get 1.35 which would be rounded to 1.4

when rounded to the nearest hundred the number of pupils in a school is 1800 what are the smallest and largest numbers of pupils

barxatty [35]

1749 should be rounded to 1700 because 1749 is closer to 1700 than to 1800

1750 should be rounded to 1800 because it is equally close to 1700 and 1800, and so you apply the rule than when the number to round finish in 5 you round to the next upper number.

Now, if you apply the same 1849 should be tha greater number that when rounded to hundreds becomes 1800.

So, the smalles and largest numbers of pupils there could be in the school are 1849 and 1750, respectively.

If ADAB<br> ACBA,<br> ZDAB = 35° and ZCBA = 8x + 3<br> A<br> D<br> x = [?]<br> X<br> C<br> B

bekas [8.4K]

Answer:

x=4

Step-by-step explanation:

We are given that the triangles are congruent.

Specifically, the order of the letters gives that the angles ∠DAB and ∠CBA are corresponding parts of the two congruent triangles. Since corresponding parts of congruent triangles are themselves congruent, ∠DAB ≅ ∠CBA. Thus, m∠DAB = m∠CBA.

Given the expressions for the two angles, we can substitute into the equation, and solve for the requested variable.

$m\angle DAB=m\angle CBA\\(35)=(8x+3)\\(35)-3=(8x+3\!\!\!\!\!\!\!\!\!\!{--})-3 \!\!\!\!\!\!\!\!\!\! {--}\\32=8x\\\dfrac {32}{8}=\dfrac {8x\!\!\!\!\!\!\! {-}}{8\!\!\!\! {-}}\\4=x$

Y = x²+1 at x=1 what’s the solution?

ArbitrLikvidat [17]

Y = x^2 + 1
if x = 1 then
y = 1^2 + 1 ( 1^2 = 1 )
y = 1 + 1
y = 2
