Answer:

Nearest ten - 950

Nearest hundred - 900

Step-by-step explanation:

Given : Number 949.

To find : What is 949 rounded to the nearest ten and hundred ?

Solution :

Rule of rounding :

1) If the rounding digit after number is greater than or equal to 5 then the number added by 1.

2) If the rounding digit after number is less than 5 then the number remain constant and rest became zero.

Round to the nearest ten,

In 949, ones place is 9>5 so the number became 950.

Round to the nearest hundred,

In 949, tens place is 4<5 so the number became 900.

Rounded to nearest ten--- 950 Rounded to nearest hundred--- 900 A trick you can use for rounding-------- 5 or more, raise the score; 4 or less, let it rest.

It would be .2 not 2 because the smaller number is first
2 divided by 10 is .2

Rajan needs 1 liter of 15% hydrochloric acid solution for an experiment. He checks his storage cabinet, but he only has a 5-lite

Delvig [45]

Answer:

0.75 liters of 5% hydrochloric acid solution
0.25 liters of 45% hydrochloric acid solution.

Step-by-step explanation:

Let us assume that, x liters of the 5% hydrochloric acid and y liters of the 45% hydrochloric acid solutions are combined.

As Rajan need total of 1 liter of solution, so

$x+y=1$

i.e $x=1-y$ --------------------1

As Rajan needs 5% hydrochloric acid and 45% hydrochloric acid to make a 1 liter batch of 15% hydrochloric acid, hence acid content of the mixture of two acids will be same as of the final one, so

$0.05x+0.45y=1\times 0.15$

i.e $5x+45y=15$ -------------2

Putting value of x from equation 1 in equation 2,

$\Rightarrow 5(1-y)+45y=15$

$\Rightarrow 5-5y+45y=15$

$\Rightarrow 5+40y=15$

$\Rightarrow 40y=15-5=10$

$\Rightarrow y=0.25$

Putting the value of y in equation 1,

$x=1-0.25=0.75$

Therefore, Rajan must use 0.75 liters of 5% hydrochloric acid solution and 0.25 liters of 45% hydrochloric acid solution.

How do I do this? Help!

Hitman42 [59]

Notice the picture below

you have two triangles, and you have the opposite and adjacent sides

thus, recall your SOH CAH TOA $\bf sin(\theta)=\cfrac{opposite}{hypotenuse}
\qquad \qquad 
% cosine
cos(\theta)=\cfrac{adjacent}{hypotenuse}

\\ \quad \\\\
% tangent
tan(\theta)=\cfrac{opposite}{adjacent}$

anyhow.. the one that has only
the angle
the opposite
and the adjacent

is Ms Tangent, so lets ask her some

$\bf tan(29^o)=\cfrac{x}{y}\implies y\cdot tan(29^o)=x
\\\\\\
tan(25^o)=\cfrac{x}{100-y}\implies (100-y)tan(25^o)=x\\\\
-----------------------------\\\\
x=x\qquad thus\qquad y\cdot tan(29^o)=(100-y)tan(25^o)$

solve for "y"
