Mary has 200ml of hand sanitizer that is 15% alcohol. She mixes it with 200ml of a
hand sanitizer that is x% alcohol,
How many milliliters of water is in the resulting mixture of hand sanitizers?
Answer:
(370-2x)ml
Step-by-step explanation:
We are given that
In first hand sanitizer
Total solution=200ml
Alcohol=15% of 200ml
Alcohol=[tex]\frac{15}{100}\times 200=30ml[/tex]
In second hand sanitizer
Solution=200 ml
Alcohol=x% of 200 ml
Alcohol=[tex]\frac{x}{100}\times 200=2x ml[/tex]
We have to find the water in the resulting mixture of hand sanitizers.
Total solution of two hand sanitizers=200+200=400ml
Total alcohol in two hand sanitizers=(30+2x)ml
Water in two hand sanitizers=400-(30+2x) ml
Water in two hand sanitizers=400-30-2x ml
Water in two hand sanitizers=(370-2x)ml
Hence, water in the resulting mixture of hand sanitizers=(370-2x)ml

4. David hikes 2 1/4 miles in 1/2 hour. At this rate how long will it take him to walk 1 mile? If he walks for 1 hour,
how far will he have gone? yes
Answer: 4.50 miles.
Step-by-step explanation:
David hikes 2 1/4 miles in 1/2 hour. To make it easier, we can turn the fractions into decimals.
David hikes 2.25 miles in 0.5 miles.
The ratio of miles hiked to the hours hiked is 2.25 : 0.5. For every 0.5 hours, David hikes 2.25 miles.
To find how many miles David walks in 1 hour, we should multiply the original ratio by 2. 0.5 x 2 = 1, and we need to find how far David walks in 1 hour.
If David hikes 2.25 miles in half an hour, then he will walk 4.50 miles in 1 hour. So the answer is that David will walk 4.50 miles in 1 hour.

19. Craig Deloy's bank computes 4.25 percent interest on a daily basis. He had $1,250 in the account
for 20 days. He then makes a deposit of $450 and makes no transactions for 10 days. He then
withdraws $300 and makes no transactions for 8 days.
a. How much interest does he earn in the 38 days total?
Answer:
Interest he earn in the 38 days total = $2458.57
Step-by-step explanation:
As given,
Rate of interest (R)= 4.25% = 0.0425
Principal (P)= $1250
Now,
Simple Interest (S.I) for 20 days = P×R×T
= 1250×0.0425×10
= 531.25
⇒Interest for 20 days = $531.25
Now,
Total amount = P + S.I = $1250 + 531.25 = $ 1781.25
As He then makes a deposit of $450 and makes no transactions for 10 days.
⇒Total amount become = $1781.25 + 450 = $2231.25
Now,
S.I for next 10 days = 2231.25×0.0425×10
= 948.28125
⇒Interest for next 10 days = $ 948.28125
∴
Total amount = $2231.25 + 948.28125 = $ 3179.53125
As He withdraws $300 and makes no transactions for 8 days.
⇒Total amount become = $ 3179.53125 - 300 = $ 2879.53125
Now,
S.I for next 8 days = 2879.53125×0.0425×8
= 979.040625
⇒Interest for next 8 days = $ 979.040625
a.)
Interest he earn in the 38 days total = Interest in 20 days + next 10 days + next 8 days
= $531.25+948.28125+979.040625
= $2458.571875 ≈ $2458.57
∴ we get
Interest he earn in the 38 days total = $2458.57

2x – 7y = -14
Write the equation in slope- intercept form
Answer:
y= 2/7x +2
Step-by-step explanation:
y = 2/7x + 2 is the slope intercept form of the equation.
Writing equation of a line in slope intercept formGiven the equation below;
2x – 7y = -14
The slope intercept form of a line is expressed as:
y = mx + b
m is the slope
b is the intercept
2x – 7y = -14
-7y = -2x - 14
7y = 2x + 14
y = 2/7x + 2
Hence the equation in slope- intercept form is y = 2/7x + 2.

the home plate in baseball which is a Pentagon has three right angle. the other two angles are equal. find the measure of each missing angle.
Answer:
Missing angle = 135°
Step-by-step explanation:
Given:
Pentagon shape
Number of right angle = 3
Remain two angles are equal
Computation:
Sum of Pentagon angles = 540°
So,
90 + 90 + 90 + a +a = 540
270 + 2a = 540
a = 135°
Missing angle = 135°

What single decimal multiplier would you use to increase by 10% followed by a 16% decrease?
The single decimal multiplier is 0.924.
What is a percentage?A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.
To find the single decimal multiplier:
First, increase by 10%.
100 + 10% = 110%
And number multiplier is 1.10.
Then, a followed by a 16% decrease.
That means,
100-16 = 84%
So, number multiplier is,
(1.10)(0.84) = 0.924
Therefore, the single decimal multiplier is 0.924.

Consider the numbers z= 2 + 5i, w = -3- 2i, and u=-1+2i.
z+w is equal to -1+vi
w-u is equal to - 4i
u + w is equal to -4 -
Answer:
3, 2, 0
Step-by-step explanation:
trust me
The resultant value of vectors are:
1. z + w = -1 + 3i.
2. w - u= -4 - 4i
3. u + w = -4.
Given:
z = 2 + 5i
w = -3 - 2i
u = -1 + 2i
1. z + w:
Adding the real and imaginary parts separately gives
(2 + 5i) + (-3 - 2i) = (2 - 3) + (5 - 2)i
= -1 + 3i
Therefore, z + w is equal to -1 + 3i.
2. w - u:
Subtracting the real and imaginary parts separately gives
(-3 - 2i) - (-1 + 2i) = (-3 + 1) + (-2 - 2)i
= -4 - 4i
Therefore, w - u is equal to -4 - 4i.
3. u + w:
Adding the real and imaginary parts separately gives
(-1 + 2i) + (-3 - 2i) = (-1 - 3) + (2 - 2)i
= -4
Therefore, u + w is equal to -4.
