Answer:
Step-by-step explanation:
The equation in standard form is:
8x + 6y = 144
To find the y-intercept, isolate y.
8x + 6y = 144
Subtract 8x from both sides.
6y = -8x + 144
Divide both sides by 6.
y = -4/3x + 24
From this, we know (0, 24) is the y-intercept because b, which in this case, is the y value for the y-intercept.
To find the x-intercept, input y as 0.
0 = -4/3x + 24
Subtract 24 from both sides.
-24 = -4/3x
Multiply both sides by 3/-4.
18 = x
The x -intercept is (18, 0).
Input 10 for y because that's how many hours you worked as a hair washer.
8x + 6(10) = 144
Simplify.
8x + 60 = 144
Subtract both sides by 60.
8x = 84
Divide both sides by 8.
x = 10.5
You worked 10.5 hours as a host.

Which coefficient before hydrogen (H2) balances this chemical equation? N2 + __H2 2NH3 A. 2 B. 3 C. 4 D. 5
Answer:
Step-by-step explanation:
The answer to this question is 3
Hope this helps
To balance the chemical equation N2 + __H2 -> 2NH3, we need to have the same number of each type of atom on both sides. We have 2 Nitrogen atoms on each side of the equation, but the Hydrogen atoms are unbalanced. By placing a coefficient of 3 before H2, we get a balanced chemical equation; N2 + 3H2 -> 2NH3. Hence, the correct answer is option B, 3.
Explanation:In order to balance a chemical equation, the same number of each type of atom must be present on both sides of the equation. In the initial chemical equation given, N2 + __H2 -> 2NH3, we have 2 Nitrogen atoms on both sides which is balanced. However, for Hydrogen we have 2 Hydrogen atoms on the left side (from H2) but 6 on the right side (as each NH3 molecule has 3 Hydrogen atoms). Therefore, we need to balance the Hydrogen atoms.
Putting a coefficient of 3 before H2 on the left side of the equation, we will have 3 * 2 = 6 Hydrogen atoms. This balances the Hydrogen atoms on both sides of the equation. Hence, the balanced chemical equation becomes N2 + 3H2 -> 2NH3. Therefore, the correct answer is B. 3.

What is the value of arccos (-1/2)
Answer:
120° & 240° (given the angles are between 0° and 360°)
Step-by-step explanation:
We want to find [tex]arccos(-\frac{1}{2})[/tex].
This means we want to know the angle(s) for which cosine has a value of [tex]-\frac{1}{2}[/tex].
The basic acute angle that has a cosine of [tex]\frac{1}{2}[/tex] is 60°. But we want to know NEGATIVE [tex]\frac{1}{2}[/tex]. So in which quadrants is cosine negative? Second and Third
The rule to find 2nd quadrant angle with known acute angle is: 180 - αThe rule to find 3rd quadrant angle with known acute angle is: 180 + αWhere α is the basic acute angle (in our case it is 60°)
So 2nd quadrant angle is 180 - 60 = 120°
and 3rd quadrant angle is 180 + 60 = 240°
Answer:
120°
Step-by-step explanation:
arccos means the inverse of cosine.
arccos (-1/2) ⇒ We can rewrite this equation as;
cosФ = 1/2 Find the value of Ф.
Ф = arccos (-1/2) ⇒ This can be calculated directly from the calculator.
arccos (-1/2) = 120°
or arccos (-1/2) = (180 + 60)
= 240°
You can have more than one value of arccos (-1/2) since the cosine is negative in the second and third quadrant.

Answer: x = 0
Step-by-step explanation:
The first step would be to convert everything to one form. I'll do the fractions, since 1/3 is hard to represent in decimal.
3 1/4 + 1/2x + 1 1/3 + 5/6x = 5 11/12
Now, the fractions will be converted via GCF. 12 is easily divisible by 4, 2, 3 and 6, so that I'll be the denominator used.
3 1/4 -> 3 3/12
1/2x -> 6/12x
1 1/3 -> 1 4/12
5/6x -> 10/12x
5 11/12 will stay the same.
The new equation is:
3 3/12 + 6/12x + 1 4/12 + 10/12x = 5 11/12
Combine like terms:
4 7/12 + 1 4/12x = 5 11/12
Subtract 4 7/12 from both sides
1 4/12x = 1 4/12
Divide both sides by 1 4/12x

The length of a diagonal of a quadrilateral shaped field Is 48 m And the length of perpendicular dropped on it from the remaining apposite vertices are 16 m and 26 m find the area of the field
Answer:
[tex]1008\text{ m}^2[/tex]
Step by step explanation:
Please find the attachment.
We have been given that the length of a diagonal of a quadrilateral shaped field Is 48 m. The length of perpendicular dropped on it from the remaining apposite vertices are 16 m and 26 m.
We can see from our attachment that diagonal AC divides our quadrilateral field into two triangular fields and AC will be the base of both triangles.
To find the area of our given quadrilateral we will find the areas of both triangles and add the areas.
Let us find area of triangle ABC with base 48 m and height 26 m.
[tex]\text{Area of triangle}=\frac{1}{2}(\text{ Base}\times\text{ Height})[/tex]
[tex]\text{Area of triangle ABC}=\frac{1}{2}\times 48\times 26[/tex]
[tex]\text{Area of triangle ABC}=24\times 26[/tex]
[tex]\text{Area of triangle ABC}=624[/tex]
Therefore, the area of triangle ABC will be 624 square meters.
Now let us find area of triangle ADC with base 48 m and height 16 m.
[tex]\text{Area of triangle ADC}=\frac{1}{2}\times 48\times 16[/tex]
[tex]\text{Area of triangle ADC}=24\times 16[/tex]
[tex]\text{Area of triangle ADC}=384[/tex]
Therefore, the area of triangle ADC will be 384 square meters.
Now let us add areas of triangles ABC and ADC to get the area of our quadrilateral ABCD.
[tex]\text{Area of quadrilateral ABCD}=384+624[/tex]
[tex]\text{Area of quadrilateral ABCD}=1008[/tex]
Therefore, the area of quadrilateral shaped field will be 1008 square meters.
In the first quarter, Owen passed the football 1 4 yards 1 foot 7 inches . On his second pass , he threw 16 yards 2 feet 19 inches .How far did he pass the football altogether ? Convert the answer to larger units whenever possible.
Answer:
31 yards 2 feet 5 inches
Step-by-step explanation:
14 yd 1 ft 7 in
+ 16 yd 2 ft 19 in
-------------------------
30 yd 3 ft 26 in
26 inches is 2 feet and 2 inches ---> 30 yd 5 ft 2 in
5 feet is 1 yard and 2 feet ---> 31 yd 2 ft 2 in
Answer:
31 yards 2 foot 2 inches
Step-by-step explanation:
To know the full distance, we need to sum both distances unit by unit. That means, we sum yards with yards, foot with foot and inches with inches. Then we converted to the larger unit whenever possible, starting from the smaller one.
Total yards: 14 + 16 = 30 yards
Total foot: 1 + 2 = 3 foot
Total inches: 7 + 19 = 26 inches
As 12 inches are 1 feet, 12*2 = 24 inches are 1*2=2 foot. Therefore, as 26 = 12*2 + 2, 26 inches are 2 foot and 2 inches.
Now we have 3 + 2 = 5 foot.
As 3 foot are 1 yard, 5 foot are 1 yard and 2 foot.
Now we have 30 + 1 = 31 yards.
Getting all together, the full distance is 31 yards 2 foot 2 inches

An airplane climbs at an angle of 11 degrees with the ground. Find the distance it has traveled when it has attained an altitude of 400 feet. Using sin, cos, and tan.
The distance traveled by the airplane to attain an altitude of 400 feet is approximately 2164.8 feet.
Explanation:To find the distance traveled by the airplane, we can use trigonometric functions.
Let's use the side opposite the angle as the altitude (400 feet) and the hypotenuse as the distance traveled.
Using the sine function, we can solve for the distance:
sin(angle) = Opposite / Hypotenuse
sin(11 degrees) = 400 feet / x
x = 400 feet / sin(11 degrees)
Using a calculator, we find that x ≈ 2164.8 feet.
Therefore, the distance traveled by the airplane to attain an altitude of 400 feet is approximately 2164.8 feet.
The distance it has traveled when it has attained an altitude of 400 feet is 2096.34 feet.
Given, Climbing angle [tex](\(\theta\))[/tex] = 11°
Altitude (opposite side) = 400 feet
sin(angle)= opposite/hypotenuse
sin(11°)= 400/d
d=400/ sin(11°)= 0.1908/400 ≈ 2096.34
The airplane has traveled approximately 2096.34 feet when it has attained an altitude of 400 feet at an angle of 11° with the ground.

The freshman class at Central High totals 522 students, with 100 more girls than boys. Which equation can be used to find the number of boys?
Answer:
The required equation is (1) and the number of boys is 211.
Step-by-step explanation:
Let the number of boys be x.
It is given that there are 100 more girls than boys. It means the number of girls is x+100.
The total number of students is 522.
Number of boys + Number of girls = 522
[tex]x+(x+100)=522[/tex] ... (1)
Combine like terms.
[tex]2x+100=522[/tex]
Subtract 100 from both the sides.
[tex]2x+100-100=522-100[/tex]
[tex]2x=422[/tex]
Divide both sides by 2.
[tex]x=211[/tex]
Therefore the required equation is (1) and the number of boys is 211.
Answer:
[tex]2x+100=522[/tex]
Step-by-step explanation:
Let the no. of boys be x
We are given that there are 100 more girls than boys.
So, No. of girls = x+100
Total number students = [tex]x+x+100[/tex]
= [tex]2x+100[/tex]
We are given that The freshman class at Central High totals 522 students
So, equation becomes : [tex]2x+100=522[/tex]
Hence an equation can be used to find the number of boys is [tex]2x+100=522[/tex]
