A scientist mixes water (containing no salt) with a solution that contains 35% salt. She wants to obtain 105 ounces of a mixture that is 15% salt. How many ounces of water and how many ounces of the 35% salt solution should she use?
Answers
Answer:
60 oz of water to add
45 oz of 35% salt solution should be used
Step-by-step explanation:
Let x = amt no. ounces in the first solution
and 105 - x = amt no. of ounces in the second solution
Ist solution contains 0% salt
2nd solution contains .35(105 - x) salt
.15(105= amt of salt in mix
So.
amt of salt in 1st solution + amt of salt in 2nd solution = amt of salt in the mix
0 + .35(105 - x) = .15(105)
Let's get rid of the fractions by multipying thru the equation by 100
35(105 - x) = 15(105)
3675 - 35x = 1575
-35x = -2100
x = 60 oz of water to add
105 - 60 = 45 oz of 35% salt solution should be used

Step-by-step explanation:
The factorisation of polynomial is (2x-1)(x+1). Therefore, option C is the correct answer.
The given expressions are 2x³-3x²-3x+2 and x-2.
What are factors of polynomial?The factors are the polynomials which are multiplied to produce the original polynomial.
Here, the given polynomial can be factored as follows:
x-2 |2x³-3x²-3x+2| 2x²+x-1
2x³-4x²
(-) (+)
___________
x²-3x+2
x²-2x
(-) (+)
___________
-x+2

____________
0
2x²+x-1 can be rewritten as 2x²+2x-x-1
= 2x(x+1)-(x+1)
= (x+1)(2x-1)
The factorisation of polynomial is (2x-1)(x+1). Therefore, option C is the correct answer.

Step-by-step explanation:
Assuming you mean
[tex]\frac{2i}{-4+3i}[/tex]
To simplify, rationalise the denominator
Multiply the numerator/ denominator by the conjugate of the denominator
The conjugate of - 4 + 3i is - 4 - 3i , then
= [tex]\frac{2i(-4-3i)}{(-4+3i)(-4-3i)}[/tex] ← expand numerator and denominator
= [tex]\frac{-8i-6i^2}{16-9i^2}[/tex] [ note that i² = - 1 ]
= [tex]\frac{-8i+6}{16+9}[/tex]

Andy mailed a third package weighing 2.5 pounds did the third package way more or less than the first package describe how you used place value blocks to compare the weights
Answers
The weights of the first and second packages are :
First package = 2.48 pounds
Second package = 2.6 pounds
Answer:
3rd is greater Than first.
Step-by-step explanation:
Weight of third package = 2.5 pounds
Comparing the weight of first and 3 rd package :
2.5 > 2.48
Weight of 3rd package > Weight of first package
First package :
2.48 pounds
Third package :
2.50 pounds
Greatest place value of the package weight is the unit value, 2 ; since the unit value is the same, we take the 2nd highest place value of the weight ;the tenth
Value of the tenth digit = 4
Value of the tenth digit in third package = 5
Since, 5 > 4 ; then 3rd weight package is greater than first weight package

You rent an apartment that costs $ 1400 $1400 per month during the first year, but the rent is set to go up $ 190 $190 per year. What would be the monthly rent during the 6th year of living in the apartment?
Answers
Answer:
$2540
Step-by-step explanation:
Given data
Cost per month=$1400
Increase per year=$190
Time = 6 years
Let the total rent per month be y
Hence, the expression for the monthly rent after 6 years is
y= 1400+190(6)
y= 1400+1140
y=$2540

E is the midpoint of DF and G is the midpoint of FH, therefore EG is the midsegment of triangle DFH, parallel to DH.
The length of the midsegment is half of the parallel side of the triangle:
EG = 1/2DHSubstitute values and solve for x:
5x + 3 = 1/2(15x - 29)10x + 6 = 15x - 295x = 35x = 7Find the length of DH:

Answers
Answer:
1/4.
Step-by-step explanation:
There are 3 even numbers in the 6 numbers on a cube.
So Probability first roll is even = 3/6 = 1/2.
By the same reason Probability of odd number = 1/2.
So: Probability(First is even and second is odd) = 1/2 * 1/2 = 1/4.
A circle has a circumference of 6. It has an arc of length 1.

60°Step-by-step explanation:
Given that:
Circumference (C) = 6 unitsArc length (A) = 1 unitFind the central angle (θ)
Arc is some part of circumference; thus,
the equation of arc length =
A = θ/360 × C
θ/360 = A/C
θ = (360×A)/C
θ = (360×1)/6
θ = 360 ÷ 6

A red-light flashes every 28 seconds. A green light flashes every 24
seconds. They both flash at the same time. After how many seconds will
they both next flash at the same time
Answers
Answer:
168 seconds
I edited the answer.
Step-by-step explanation:
To find the the time taken for both lights to flash at the same time, we need to find the lowest common multiple of 28 and 24.
28 x 6 = 168, 24 x 7 = 168
The LCM of 28 and 24 is 168.
So it takes 168 seconds for both lights to flash at the same time.
Both lights will flash together again at 2 minutes and 8 seconds.
To find When will they flash together again if they flash together.
What is LCM?LCM is the method to find the smallest possible multiple of two or more numbers.
Given that,
A red light flashes once every 28 seconds
A green light flashes once every 24 seconds
A red light flashes every 28 seconds and green light flashes once every 32 seconds. Therefore, we have to find their least common factor.
LCM(28 , 24) = 168
The red and green light will flash together after every 168 seconds.
Time =168 seconds
Time =168 / 60 minutes
Time = 2 minutes and 8 seconds
The red and green light will flash together after every 2 minutes and 8 seconds.
Hence, both lights will flash together again at 2 minutes and 8 seconds.
