What quantity of 61% hydrochloric acid solution must be mixed with a 21% hydrochloric acid solution to produce 277.5 mL of 53% solution?
Answer:
222 mL
Step-by-step explanation:
okay so lets multply them lets call the quantity of hydrocloric acid x
so 61x+ 21(277.5-x)= 53*277.5
61x+ 21*277.5-21x= 53*277.5
40x=(53-21)(277.5)
40x= (32)(277.5)
x= 222 mL

What should be added to p2+ pq + r2 to get 2p2+ 5pq?
2p2 + 5pq
p2+4pq - r2
p2+ 5pq
p2+ 4pq
Answer: p2+4pq - r2
Step-by-step explanation:
p2+ pq + r2 + p2 + 4pq - r2
First, rearrange so like terms a beside each other.
p2 + p2 + pq + 4pq +r2 - r2
= 2p2 + 5pq

can you write equivalent fractions for 2 1/5 and 1 and 5/6 using 30 of the common denominator
Answer:
yes they would be 1 25/30 and 2 6/30
Step-by-step explanation:
The equivalent fractions for 2 1/5 and 1 and 5/6 using 30 of the common denominator would be 1 25/30 and 2 6/30
What is a fraction?A fraction has two parts: Numerator and Denominator.
It is in the form of a Numerator / Denominator. A fraction is a numerator divided by the denominator.
We need to write equivalent fractions for 2 1/5 and 1 and 5/6 using 30 of the common denominator .
Now consider the first fraction as;
2 1/5 = 11/5
Then other fraction must be multiple of the denominator of the other.
So, 1 and 5/6 = 11/6
We can see that "the denominator of one is a multiple of the denominator of other" that is 5 x 6 = 30
Thus the two fractions are; 1 25/30 and 2 6/30

Simplify the following using the Distributive Property: -2(x+10)
Answer:
[tex]\bold{-2x-20}[/tex]
Step-by-step explanation:
Hi there!
Let's clarify what the Distributive Property is.
It's a property that states
[tex]\bold{a(b+c)=ab+ac}[/tex]
So, we take a number a, multiply it by b and c, and add the products.
Now, let's use this property to simplify our expression:
[tex]\bold{-2(x+10)}[/tex]
[tex]\bold{-2x-20}[/tex]
Hope it helps! Enjoy your day!

Step-by-step explanation:
50 + 7x = 67.50 x is the cost she deposited every week
7x = 17.5
x = 2.5
Find the curved surface area of a cylinder diameter 12cm and length 30cm (fast plz)
Answer:
solution:-
diameter of a cylinder (d) = 12 cm
length(h) = 30 cm
curved surface area of cylinder (csa) = ?
we know that ,
therefore , csa of cylinder = 2πrh
r = d/2
or, r = 12/2= 6 cm
Then, csa if cylinder = 2 ×22/7×30
= 2×22×30/7
= 1320/7

Construct equilateral triangle with sides, ABC such that AB = AC = CB = 10.5 cm. Measure and write down the size of angle < ABC.
Answer:
∠ABC = 60°
Step-by-step explanation:
All angles in equilateral triangles are equal.
all angles in triangles added together = 180°
180°/3 = 60°
All angles in equilateral triangles are equal to 60°.

2. What is the length of
side c? Someone help
Answer:
Side c has a length of √145, or approximately 12.04.
Step-by-step explanation:
Because this is a right triangle, you can use the Pythagorean theorem to solve it. In a right triangle, the sum of the squares of the two sides is equal to the square of the hypotenuse. Or in this example:
c² = 9² + 8²
So we can solve it:
c² = 9² + 8²
c² = 81 + 64
c² = 145
c = √145
c ≈ 12.04

Damian invested $880 in an account paying an interest rate of 5.2% compounded
annually. Assuming no deposits or withdrawals are made, how long would it take, to the nearest tenth of a year, for the value of the account to reach $1,290?
Answer:
Step-by-step explanation:
880×1.052^t = 1290
1.052^t = 1290/880 = 129/88
t ≅ 7.5 years
Answer:
7.5 yearsStep-by-step explanation:
Given:
Investment P = $880Interest rate r = 5.2% = 0.052 timesCompound number n = 1 (annual)Time t = ?Final amount A = $1290The equation is below, solve for t:
A = P(1 + r/)^(nt) 1290 = 880(1 + 0.052)^t1.052^t = 1290/8801.052^t = 1.4659t = log 1.4659 / log 1.052t = 7.5 years (rounded)Which shape is NOT a trapezoid?

if exchange rate is#420 to a $, then #200.000.00 in $
Answer:
$476.19
Step-by-step explanation:
Given data
Exchange rate
We are told that #420 represents $1
We want to find the dollar equivalent of #200,000.00
if #420 represents $1
then #200,000 represents x
cross multiply
x= #200,000/420
x= $476.19
Hence the eqivalent is $476.19
251.2 ÷ 1.2 round to nearest thousands
Someone please explain this it’s confusing me.
Answer:
x = 4 radical 3 / 3
Step-by-step explanation:
this is a 30-60-90 triangle
the side across from the angle 30 is L
the side across from the angle 60 is L√3
the side across from the angle 90 is 2L
we are given the side across from 60⁰ so we know that:
2 = L√3
we want to solve for L, so we must divide both sides by √3 (radical three)
2/√3 = L√3/√3
you would get 2/ √3 = L, because the radical three cancels out on the L side.
but you can't have a radical in the denominator, so you have to multiply 2/√3 by radical 3
2 times √3 and √3 times √3
you get 2√3/√9
radical nine can simplify
2radical3/3 or 2√3/3
we found L, but that would equal the thirty degree angle, not the 90, 90 = 2L
multiply the number infront of the radical by two and get
4√3/3
x=4 radical 3 divided by 3
