What are the angle measures of triangle ABC?
mA= 30°, m ZB = 60°, m 2C = 90°
mZA= 90°, m ZB = 60°, m 2C = 30°
mZA= 60°, m ZB = 90°, m2C = 30°
mZA= 90°, m ZB = 30°, m2C = 60°
∠A = 90°, ∠B = 60° and ∠C = 30°
Step-by-step explanation:
Step 1: Find whether the triangle is a right angled triangle by using Pythagoras theorem. Given sides are a = 24 (opposite to ∠A), b = 12√3 (opposite to ∠B) and c = 12 (opposite to ∠C).⇒ 12² + (12√3)² = 144 + 432 = 576
⇒ √576 = 24 = a. This shows that the triangle is a right angled triangle.
So ∠A = 90°
Step 2: Use trigonometric equations to determine the other angles.⇒ cos B = AB/BC = 12/24 = 1/2
⇒ ∠B = 60°
Step 3: The sum of the angles in a triangle is 180°. To find ∠C,⇒ ∠C = 180° - (90° + 60°) = 180° - 150°
⇒ ∠C = 30°
The angle measures of triangle ABC is therefore;
mZA= 90°, m ZB = 60°, m ZC = 30°
Angle measures of Right trianglesBy testing for Pythagoras triple;
24² = 12² + (12√3)²576 = 144 + 432576 = 576.Hence, the triangle is a right-angled triangle.
We can then evaluate mZC as follows;
Sin C = 12/24 = 0.5C = Sin-¹(0.5) = 30°And angle B = 180 - 30 -90Angle, B = 60°Read more on angle measures in triangles;

kim's hourly wage is $14. she works 37 hours per week. what is her weekly income? what is her monthly income?kim can pay at most 30% of her income on rent. what is the most she can pay for rent every month?
Answer:
Weekly income = $518
Monthly income = $2072
Rent = $621.6
Step-by-step explanation:
$14 per hour
37 hours per week
37 × 14 = $518
There is about 4 weeks in a month.
$518 × 4 = $2,072
30% of $2,072 = $621.6
Step-by-step explanation:
Kim's weekly income can be found by multiplying her hourly wage to the number of hours she works per week.
So, we have $14 * 37 = $518 weekly income.
Let's assume that Kim gets paid bi-weekly like most jobs, so she'll get paid twice a month usually, ignoring all holidays and other exceptions.
So, we have her weekly income and we are assuming she gets paid bi-weekly per month. So, we need to make her weekly income into a bi-weekly income. We just double her weekly income.
$518 * 2 = $1036 bi-weekly.
Now, we know are assuming she gets paid twice a month, so we need to double her income one more time.
$1036 * 2 = $2072 monthly income.
Now, we have her monthly income, but she can only pay 30% of it towards rent. So, we got to find out what is 30% of $2072.
There are a couple of ways to do this, but the most efficient way is to multiply $2072 by .3
So, $2072 * .3 = $621.60
She can only have $621.60 go towards rent. Hope this helps!

Solve: 746 ÷ 11
Show the remainder as a fraction.
The correct answer is [tex]67\frac{9}{11}[/tex]
Write the problem in long division format,
Divide 74 by 11 to get 6,
Multiply the quotient digit (6) by the divisor 11,
Subtract 66 from 74,
Bring down the next number of the dividend,
Divide 86 by 11 to get 7,
Multiply the quotient (7) by the divisor 11,
subtract 77 from 86.
[tex]\(746 \div 11\)[/tex] equals 67 with a remainder of 9. The remainder expressed as a fraction is [tex]68\frac{2}{11}\).[/tex]
To solve the division problem 746 ÷ 11 and express the remainder as a fraction, we can perform the long division as follows:
Step 1: Divide 7 by 11, which is 0 with a remainder of 7. So, the first digit of the quotient is 0, and we bring down the next digit, which is 4, to form the dividend 74.
Step 2: Now, divide 74 by 11. The largest multiple of 11 that does not exceed 74 is 6 times 11, which is 66. The remainder is 74 - 66 = 8.
Step 3: Bring down the next digit, which is 6, to form the new dividend 86.
Step 4: Divide 86 by 11. The largest multiple of 11 that does not exceed 86 is 7 times 11, which is 77. The remainder is 86 - 77 = 9.
Step 5: Finally, bring down the last digit, which is 0, to form the new dividend 90.
Step 6: Divide 90 by 11. The largest multiple of 11 that does not exceed 90 is 8 times 11, which is 88. The remainder is 90 - 88 = 2.
Now, we have completed the long division. The quotient is 68, and the remainder is 2. To express the remainder as a fraction, we can write it as [tex]\(\frac{2}{11}\).[/tex]
So, [tex]\(746 \div 11 = 68\frac{2}{11}\).[/tex]

same mhethod for:(1, 2)
The solutions are B) (0, 6) and (1, 2).
To find the solutions to the given system of equations:
y = x² − 5x + 6 and y = −4x + 6, we need to set the equations equal to each other and solve for x:
Set x² − 5x + 6 equal to −4x + 6:
x² − 5x + 6 = −4x + 6
Rearrange the equation to get:
x² − x = 0
Factor the equation:
x(x − 1) = 0
Solve for x:
x = 0 or x = 1
Substitute these values back into either original equation to find y:
When x = 0: y = −4(0) + 6 = 6 (so one solution is (0, 6)).
When x = 1: y = −4(1) + 6 = 2 (so another solution is (1, 2)).
Therefore, the solutions to the system of equations are B) (0, 6) and (1, 2)

family has an annual income of $23 comma 400. Of this, one fourth
is spent for food, one fifth
for housing, one tenth
for clothing, one ninth
for savings, one fourth
for taxes, and the rest for other expenses. How much is spent for each?
$
nothing is spent for food.
Amount spent for food = $5850, housing = $4680, clothing = $2340, savings = $2600, taxes = $5850, expenses = $2080.
Step-by-step explanation:
Step 1:
Given details are Total Income = $23,400
Step 2:
Amount spent for food, F= 1/4th of 23,400 = [tex]1/4 \times 23400[/tex]
= $5850
Step 3:
Amount spent for housing, H = 1/5th of 23,400 = [tex]1/5 \times23400[/tex]
= $4680
Step 4:
Amount spent for clothing, C = 1/10th of 23,400 = [tex]1/10 \times 23400[/tex] = $2340
Step 5:
Amount spent for savings, S = 1/9th of 13,400 = [tex]1/9\times 23400[/tex] = $2600
Step 6:
Amount spent for taxes, T = 1/4th of 23,400 = [tex]1/4 \times 23400[/tex] =$5850
Step 7:
Find amount spent on other expenses by totaling all expenditures and subtracting from the annual income.
Annual Income = F + H + C + S + T + E
Amount spent on other expenses, E = 23400 - (5850 + 4680 + 2340 + 2600 + 5850)
E = 23400 - 21320
E = $2080
A pond initially contains 1000000 gal of water and unknown amount of an undesirable chemical. water containing 0.01 g of his chemical per gallon flows into the pond at a rate of 300 gal/h.the mixture flows out at the same rate ,so the amount of water in the pond remains constant .Assume that the chemical is uniformly distributed throughout the pond .How much of the chemical will be in the pond after a very long time ?
Final answer:
To calculate the amount of chemical in the pond after a very long time, multiply the rate at which the chemical flows in per hour by the number of hours that have passed.
Explanation:
To find out how much of the chemical will be in the pond after a very long time, we can first calculate the amount of chemical that flows into the pond per hour. Since 0.01 g of chemical flows in per gallon, and the rate of flow is 300 gallons per hour, the amount of chemical added per hour is 0.01 g/gal * 300 gal/hr = 3 g/hr.
Since the amount of water in the pond remains constant, the concentration of the chemical will also remain constant. Therefore, after a very long time, the amount of chemical in the pond will be the amount added per hour multiplied by the number of hours that have passed. So, if time is represented by 't', then the amount of chemical in the pond after a very long time is given by 3 g/hr * t.

Therefore, the fraction is numerator/denominator (to the nearest tenth) =
A.73.1%
B.65.4%
C.136.8%
Answer:
The numerator is 57 ⇒ B
The denominator is 78 ⇒ B
The value of the fraction is 73.1% ⇒ A
Step-by-step explanation:
Let us solve it step by step
∵ The loan is 12 month
∵ The numerator is after 6 month
- Put n = 1 in each bracket
∴ The numerator = {(1 + 11) + (1 + 10) + (1 + 9) + (1 + 8) + (1 + 7) + (1 + 6)}
∴ The numerator = {12 + 11 + 10 + 9 + 8 + 7}
∴ The numerator = {57}
The numerator is 57
∵ The denominator = {(n) + (n + 1) + (n + 2) + .......... + (n + 11)}
- Do the same as the numerator put n = 1
∴ The denominator = {1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 + 11 + 12}
∴ The denominator = {78}
The denominator is 78
Now find the value of the fraction
∵ The fraction = [tex]\frac{57}{78}[/tex]
∴ Its value = 0.730769230
- Multiply it by 100%
∴ Its value = 0.730769230 × 100% = 73.0769230%
- Round it to the nearest tenth
∴ Its value = 73.1%
The value of the fraction is 73.1%
Is it undefined? I'm not sure.
Answer:
no
Step-by-step explanation:
the line has a value which is y=7
Answer: Zero slope
Step-by-step explanation: A common mistake made by many students is to confuse what no slope is and what zero slope.
If a line has a slope of zero, it means that the line is flat or horizontal.
No slope is a vertical line or straight up and down. No slope means that we cannot describe its slope using a number because its line is vertical and it's slope is undefined. This has to do with dividing a number by 0. When you do this, you should get an error message or it should say undefined.
So, this line would have zero slope because it's flat.

Step-by-step explanation:

4y=6-3x
4y=-3x+6
y=(-3/4)x+3/2
To convert 3x + 4y - 6 = 0 to y = mx + b form is :[tex]y = -\frac{3}{4}x + 1.5.[/tex]
The equation given is 3x + 4y - 6 = 0. To write it in y = mx + b form, follow these steps:
Add 6 to both sides of the equation: 3x + 4y = 6.Subtract 3x from both sides to isolate the y-term: 4y = -3x + 6.Divide every term by 4 to solve for y:[tex]y = -\frac{3}{4}x + \frac{6}{4}.[/tex]Simplify the constants:[tex]y = -\frac{3}{4}x + 1.5.[/tex]Now, the equation is in slope-intercept form where m (the slope) is[tex]-\frac{3}{4}[/tex] and b (the y-intercept) is 1.5.
