Answers
Answer:
3d-12=b
Step-by-step explanation:
Answer:3d − 12.
Step-by-step explanation:
Dylan’s weight is d.
Three times Dylan’s weight is 3d.
Twelve less than three times Dylan’s weight is 3d − 12.
So, the expression for Bruce’s weight in terms of Dylan’s weight is 3d − 12.

Jim rode at average speed of 12 mph for 2 hours. Then, he
walked at average speed of 3 mph for 0.5 hour. What was the
total distance covered by Jim?
miles
Answers
Answer:
25.5 miles
Step-by-step explanation:
The distance is equal to speed multiplied by time. When Jim rode at 12 mph for 2 hours, that means her rode for 24 miles(12*2), then he walked at 3 mph for half an hour, that means he walked for 1.5 miles(3*1/2). Add them both together, you get 25.5 miles.
The total distance covered by Jim is 25.5 miles.
Calculating distancesTo find the total distance covered by Jim, we need to add the distances covered while riding and walking.
Distance covered while riding = Speed * Time = 12 mph * 2 hours = 24 milesDistance covered while walking = Speed * Time = 3 mph * 0.5 hours = 1.5 milesTotal distance covered = 24 miles + 1.5 miles = 25.5 miles
Therefore, the total distance covered by Jim is 25.5 miles.

A baseball is hit so that its height in feet after t seconds is s(t) = - 4t"" + 20t+2.
(a) How high is the baseball after 1 second?
(b) Find the maximum height of the baseball.
Answers
Answer with Step-by-step explanation:
We are given that
Height of ball after t seconds is given by
[tex]s(t)=-4t^2+20t+2[/tex]
a.Substitute the value of t=1
[tex]s(1)=-4(1)+20(1)+2=-4+20+2=18 ft[/tex]
b.Differentiate w.r.t x
[tex]s'(t)=-8t+20[/tex]
[tex]s'(t)=0[/tex]
[tex]-8t+20=0[/tex]
[tex]8t=20[/tex]
[tex]t=\frac{20}{8}=2.5[/tex]
Again differentiate w.r.t t
[tex]s''(t)=-8<0[/tex]
Hence, the height is maximum at t=2.5 s
[tex]s(2.5)=-4(2.5)^2+20(2.5)+2=27[/tex]

Which equation is a correctly written thermochemical equation?
C3H8 (g) + 5O2 (g)→3CO2 (g) + 4H2O (l) , ΔH= −2,220 kJ/mol
Fe (s) + O2 (g)→Fe2O3 (s) , ΔH= −3,926 kJ
NH4Cl→NH4 + + Cl−
2C8H18 + 25O2→16CO2 + 18H2O , ΔH= −5,471 kJ/mol
Answers
Correctly written thermochemical equations include gaseous, liquid, or solid state indications as well as the enthalpy change, ΔH. Out of the presented options, the equations for C3H8(g), Fe(s), and 2C8H18 correctly represent thermochemical equations, but NH4Cl does not due to lacking these features.
Explanation:The question is asking which equation is a correctly written thermochemical equation. A thermochemical equation is a balanced stoichiometric chemical equation that includes the enthalpy change, ΔH.
Looking at the given equations, the first is:
C3H8(g) + 5O2(g)→3CO2(g) + 4H2O(l) , ΔH= −2,220 kJ/mol. This is a correct thermochemical equation.
The second equation is:
Fe(s) + O2(g)→Fe2O3(s) , ΔH= −3,926 kJ. This is also a correct thermochemical equation.
The third equation lacks the gaseous, liquid, or solid state indications as well as the ΔH value, therefore it is not a thermochemical equation.
The fourth equation, 2C8H18 + 25O2→16CO2 + 18H2O , ΔH= −5,471 kJ/mol, is definitely an example of a correct thermochemical equation.

PLEASE HURRY!! I HAVE LIMITED TIME!! :)
Answers
Given:
Given that the radius of the circle is 9 units.
The measure of the angle JHG is 160°
We need to determine the area of the shaded sector of the circle.
Area of the circle:
The area of the circle can be determined using the formula,
[tex]A=(\frac{\theta}{360}) \pi r^2[/tex]
where r is the radius
Substituting r = 9 and [tex]\theta=160[/tex], we get;
[tex]A=(\frac{160}{360}) \pi (9)^2[/tex]
Simplifying, we get;
[tex]A=(\frac{160}{360}) \pi (81)[/tex]
[tex]A=36 \pi[/tex]
Thus, the area of the shaded sector of the circle is 36π units²
Hence, Option a is the correct answer.
Which equation represents a line with a slope of 3 and y-intercept of -4?
a y = 3x -4
b y =4x −3
c y=−3x +4
d y=−4x + 3
Answers
Slope-intercept form: y = mx + b
(m is the slope, b is the y-intercept or the y value when x = 0 --> (0, y) or the point where the line crosses through the y-axis)
You know:
m = 3
b = -4 So substitute/plug it into the equation
y = mx + b
y = 3x + (-4)
y = 3x - 4 Your answer is a
The equation representing a line with a slope of 3 and a y-intercept of -4 is y = 3x - 4. Hence, the correct option is (a).
The student's question pertains to finding the equation of a line with a given slope and y-intercept. In the slope-intercept form of a linear equation, which is y = mx + b, the m represents the slope, and the b represents the y-intercept. Therefore, for a line with a slope of 3 and a y-intercept of -4, the corresponding equation would be y = 3x - 4.
So, the correct answer is:
y = 3x - 4
This is because it directly shows a slope (m) of 3 and a y-intercept (b) of -4, which matches the line properties the question is asking for.

Ms. van Vugt is making brownies. Her recipe calls for 1/2 cup of milk for 12 brownies. She is making 48 brownies. How much milk does she need? (HINT: How many cups are in a pint?) *
Answers
Answer: Ms. Van Vugt will need 2 cups of milk or 1 pint of milk to make 48 brownies.
Step-by-step explanation: For this situation, we know for every 12 brownies she will use 1/2 cup of milk. So we can count up for every 12 brownies.
12 brownies = 1/2 cup of milk
24 brownies = 1 cup of milk
36 brownies = 1 1/2 cup of milk
48 brownies = 2 cups of milk
So, Ms. Van Vugt will need 2 cups of milk or 1 pint of milk to make 48 brownies.

What is the equation of the line that passes through (-2, 2) and (1, -4)?
y=2x-2
y=-2x-4
y=-2x-2
y= 2x+4
Answers
Answer:
y = - 2x - 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ = (- 2, 2) and (x₂, y₂ ) = (1, - 4)
m = [tex]\frac{-4-2}{1+2}[/tex] = [tex]\frac{-6}{3}[/tex] = - 2, thus
y = - 2x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (- 2, 2), then
2 = 4 + c ⇒ c = 2 - 4 = - 2
y = - 2x - 2 ← equation of line

Final answer:
To calculate Mr. Rich's take-home pay, add together the regular and overtime pay, then subtract the deductions. The result is a take-home pay of $10,737 that is option A is correct.
Explanation:
The student is asking how to calculate the take-home pay for Mr. Rich after deductions from his income. To find the take-home pay, we first add together Mr. Rich's regular pay and overtime pay to get his total earnings. Then, we subtract the deductions to find the amount he takes home.
Regular pay: $9,278
Overtime pay: $2,132
Total earnings before deductions: $9,278 + $2,132 = $11,410
Deductions (taxes and loan): $673
Take-home pay: $11,410 - $673 = $10,737
Right triangle FHG is shown. The sine of angle F is 0.53. What is the cosine of Angle h ?
Answers
Given:
Given that FGH is a right triangle. The sine of angle F is 0.53.
We need to determine the cosine of angle H.
Cosine of angle H:
Given that the sine of angle F is 0.53
This can be written as,
[tex]sin F=0.53[/tex]
Applying the trigonometric ratio, we have;
[tex]\frac{HG}{FH}=0.53[/tex] ----- (1)
Now, we shall determine the value of cosine of angle H.
Let us apply the trigonometric ratio [tex]cos \ \theta=\frac{adj}{hyp}[/tex], we get;
[tex]cos \ H=\frac{HG}{FH}[/tex] ----- (2)
Substituting the value from equation (1) in equation (2), we get;
[tex]cos \ H=0.53[/tex]
Thus, the cosine of angle H is 0.53
