A lab technician mixes a 10% acid solution with a 50% acid solution to create 40 ml of a 40%
solution. How much of each solution must be used?
Answer:
10 ml of 10%
30 ml of 50%
Step-by-step explanation:
x = amount of 10%
40 - x = amount of 50%
-------------------------------------
10x + 50(40 - x) = 40(40)
10x + 2000 - 50x = 1600
-40x + 2000 = 1600
-40x = -400
x = 10 ml of 10%
40 - x = 30 ml of 50%

Determine two coterminal angles (one positive and one negative) for each angle. Give your answers in degrees. (Enter your answers as a comma-separated list.) −420°
Answer:
- 420° = -7/3 π ≈ - 2.333 π
Step-by-step explanation:
- 420° = -7/3 π ≈ - 2.333 π
Coterminal angle in [0, 360°) range:
300°, located in the fourth quadrant.
Positive coterminal angles: 300°, 660°, 1020°, 1380°, 1740°...
Negative coterminal angles: -60°, -420°, -780°, -1140°
I hope this helps!1!!
-420° = -360° - 80° = -80°
-80° = 360° - 80° = 280°
Co terminal angle = 280° and -80°

A survey was given to a random sample of 550 voters in the United States to ask about their preference for a presidential candidate. Of those surveyed, 264 respondents said that they preferred Candidate A. Determine a 95% confidence interval for the proportion of people who prefer Candidate A, rounding values to the nearest thousandth.
The 95% confidence interval for the proportion of people who prefer Candidate A is given as follows:
(0.438, 0.522).
What is a confidence interval of proportions?A confidence interval of proportions has the bounds given by the rule presented as follows:
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which the variables used to calculated these bounds are listed as follows:
[tex]\pi[/tex] is the sample proportion, which is also the estimate of the parameter.z is the critical value.n is the sample size.The confidence level is of 95%, hence the critical value z is the value of Z that has a p-value of [tex]\frac{1+0.95}{2} = 0.975[/tex], so the critical value is z = 1.96.
The parameters for this problem are given as follows:
[tex]n = 550, \pi = \frac{264}{550} = 0.48[/tex]
Hence the lower bound of the interval is obtained as follows:
[tex]0.48 - 1.96\sqrt{\frac{0.48(0.52)}{550}} = 0.438[/tex]
The upper bound of the interval is obtained as follows:

5b) Through the lease, the customer saves $14,760.
5c) The lease options for the lessee after returning the car include:
Lease buyoutLease extensionNew lease contractBuying out the vehicle and then reselling it.6a) The after-tax cost of the Honda Civic is $32,199.35.
6b) The value of the vehicle that needs to be financed is $26,199.35.
6c) The monthly payment will be $567.26 for 4 years.
6d) After four years, the total amount paid for the vehicle is $33,228.48.
Financing Options:A lease is a financing option for the use of capital assets by which the lessee utilizes an asset for a stated period while making periodic payments to the lessor.
A car purchase can also be financed through loans, like home mortgages.
Value of the car = $32,000
Harmonized Sales Tax (HST) = 13%
Cost of the car with HST = $36,160 ($32,000 x 1.13)
Lease Arrangement:Down payment = $1,000
Financing part = $35,160 ($36,160 - $1,000)
Installment payments = 48
Periodic payments = $425
Total lease cost = $21,400 ($1,000 + 48 x $425)
Savings (advantages) from leasing = $14,760 ($36,160 - $21,400)
Jordan's Car:The value of the Honda Civic = $28,495
Harmonized Sales Tax (HST) = 13%
After-tax cost = $32,199.35 ($28,495 x 1.13)
Annual interest rate = 1.9% compounded monthly
Down payment = $6,000
Financing part = $26,199.35 ($32,199.35 -$6,000)
Financing period = 4 years
N (# of periods) = 48 months (4 years x 12)
I/Y (Interest per year) = 1.9%
PV (Present Value) = $26,199.35
FV (Future Value) = $0
P/Y (# of periods per year) = 12
C/Y (# of times interest compound per year) = 12
Results:
Monthly Payments (PMT) = $567.26
Sum of all periodic payments = $27,228.48
Total Interest $1,029.13
Total amount paid over 4 years = $33,228.48 ($27,228.48 + $6,000)

In the BioPsyc building exterminators find that the allele frequency of the gene for short tale in mice in the building to me 0.2. Due to construction in the BioPsyc building several of the mice made HJP their new home. The exterminator guessed that about 20% of the mice in HJP now consist of mice from BioPsyc. What will be the new frequency of the short tales among mice in HJP?
a. 0.43.
b. 0.65.
c. 0.57.
d. 0.60.
The new frequency of short tail mice in HJP is 0.60.
What is Algebra?Algebra is a branch of mathematics that deals with symbols or variables and uses arithmetic operations (+, –, ×, ÷) to find the unknown quantities represented by these variables.
Let, initial number of mice in HJP be 'x'
and the number of mice travelling from BioPyc building to HJP be 'ý
So, Total mice in HJP= x+ y
As, [tex]\frac{y}{x+y} = 0.2[/tex]
y= 0.2x + 0.2 y
0.8y =0.2 x
x= 4y
Now, total short tail mice in HJP= 0.7 x + 0.2 y
Thus, New frequency of short tail among mice in HJP
= [tex]\frac{0.7x + 0.2y}{x+y}[/tex]
Put x= 4y in above equation we get,
= [tex]\frac{0.7 * 4y+ 0.2y}{4y+y}[/tex]
= [tex]\frac{3y}{5y}[/tex]
= 0.60
Hence, the new frequency of short tail mice in HJP is 0.60.

What are trigonometry ratios?
Trigonometric ratios are based on the value of the ratio of sides of a right-angled triangle and contain the values of all trigonometric functions. The trigonometric ratios of a given acute angle are the ratios of the sides of a right-angled triangle with respect to that angle.
Draw a line parallel to the base.
Name the corner point of the shape.
Assume that ∠ADG = θ.
Consider △BDF:
BD = 6 + x
DF = 8 + 4.8 = 12.8 yrds.
The cosine of an angle is the ratio of the base to the hypotenuse of the right-angle triangle.
cos θ = DF/BD
cos θ = 12.8 /(6+x) .....(i)
Consider △CDE:
cos θ = DE/CD
cos θ = 8/x .....(ii)
Now equate equations (i) and (ii):
12.8 /(6+x) = 8/x
Cross multiply:
12.8 × x = 8(6+x)
12.8x = 48 + 8x
12.8x - 8x = 48

an
The angle measure of ∠F is approximately 66.9º.
What is an angle?
To find ∠F, we can use the Law of Cosines:
c² = a² + b² - 2ab cos(C)
Where c is the side opposite to the angle we want to find (in this case, side EF), a and b are the other two sides, and C is the angle opposite to side c (in this case, ∠F).
First, we need to find the length of side EF:
EF² = DE² + DF² - 2DE * DF cos(∠D)
EF² = (9.8)² + (5.6)² - 2(9.8)(5.6)cos(149º)
EF² ≈ 95.415
EF ≈ 9.769
Now, we can use the Law of Cosines again to find ∠F:
EF² = DE² + DF² - 2DE * DF cos(∠F)
cos(∠F) = (DE² + DF² - EF²) / 2DE * DF
cos(∠F) = ((9.8)² + (5.6)² - (9.769)²) / (2 * 9.8 * 5.6)
cos(∠F) ≈ 0.4035
∠F ≈ [tex]cos^{-1(0.4035)}[/tex]
∠F ≈ 66.9º (rounded to the nearest 10th)
Therefore, the measure of ∠F is approximately 66.9º.
