Which expression can be used to determine 50% of 42? 42 minus 2 42 divided by 2 42 divided by 10 42 minus 10
Answer:
We know that 50% of 42 will be = 21
i.e. 50% of 42 = 50/100 = 21The correct answer should be: 42 divided by 2
Step-by-step explanation:
We know that 50% of 42 will be = 21
i.e. 50% of 42 = 50/100 = 21Also, when we divide 42 by 2, we get the answer 21.
i.e. 42/2 = 21Therefore, the correct answer should be: 42 divided by 2

A linear function models the height of a burning candle. Candle A comes out of the mold at 211 mm, and is expected to be at 187 mm after 8 hours of burning. The model for Candle B is h=210−5t, where h is the height in millimeters and t is the time in hours. What are the initial values for each candle? What do the initial values for each candle tell you?
Given:
Candle A comes out of the mold at 211 mm, and is expected to be at 187 mm after 8 hours of burning.
The model for Candle B is
[tex]h=210-5t[/tex]
where, h is the height in millimeters and t is the time in hours.
To find:
The initial values for each candle and its interpretation.
Solution:
Candle A comes out of the mold at 211 mm, and is expected to be at 187 mm after 8 hours of burning.
So, initial value of candle A = 211 mm
The model for Candle B is
[tex]h=210-5t[/tex]
Putting t=0, we get
[tex]h=210-5(0)[/tex]
[tex]h=210-0[/tex]
[tex]h=210[/tex]
So, initial value of candle B = 210 mm
Initial values for each candle tell you about the height of the candles before they start burning.
Initial value of candle A is greater than B, so the height of candle A is greater than B before they start burning.
Therefore, the initial value of candle A is 211 mm and initial value of candle B is 210 mm.

A line drawn from one side of a circular plate to the other, through the center of the plate, measures 25 centimeters.
What is the approximate area of the plate to the nearest square centimeter?
39 centimeters²
79 centimeters²
156 centimeters²
491 centimeters²
Answer:
39 centimeters
Step-by-step explanation:
to find the area of a circle you first find the radius which is the disctance from the edge of the plate to the center. you then multiply it by pi to find the total area.
The required area of the given plate with a diameter of 25 centimeters is 491 centimeters². Option B is correct.
What is an area circle?The area of the circle is given by the pie times square of the radius.
Area of circle = πr^2
here,
A line drawn from one side of a circular plate to the other, through the center of the plate, measures 25 centimeters.
So, the Diameter of the plate = 25 centimeters,
The area of the plate is given as,
Area of plate = π × [diameter/2]²
= 3.14 × [25/2]
= 491 centimeters²
Thus, the required area of the given plate is 491 centimeters². Option B is correct.

A _____ magnet can be made by rubbing a permanent magnet the same way
along an item. The alignment of atoms does not last long.
permanent
temporary
atomic
polar
Answer:
permeant
Step-by-step explanation:
Stroking with one pole of a permanent magnet works because it aligns the atoms in the nail to line up in the same polar direction, giving the nail a north and a south magnetic pole.
If 4m + 1 = 7 then 4m = 6
1) Symmetric Property 2) Subtraction Property of Equality
3) Substitution Property 4) Transitive Property
Answer:
2) Subtraction Property of Equality Properties
General Formulas and Concepts:
Pre-Algebra
Addition Property of Equality - Adding on both sidesSubtraction Property of Equality - Subtracting on both sidesMultiplication Property of Equality - Multiplying on both sidesDivision Property of Equality - Dividing on both sidesTransitive Property - If a = b and b = c, then a = cSymmetric Property - If a = b then b = aStep-by-step explanation:
Step 1: Define
4m + 1 = 7 → 4m = 6
Step 2: Identify
We see that we subtracted on on both sides of the equation. Therefore, we would have to use the Subtraction Property of Equality. Therefore, 2 is our answer.

Which phrase matches the algebraic expression below?
2(x - 7) +10
Answer:
2 times the difference of x minus 7 plus 10
Step-by-step explanation:
When dealing with equations, you ALWAYS do the parentheses first. The first relationship x and 7 are going to have is being subtracted from eachother. Once you do that, you can do the rest of the equation. Hope this helps!

Answer is C multiply 5 by every ticket
Step-by-step explanation:
what is 1/4 divided by 5.
Answer: 1/20 or 20
Step-by-step explanation:
Please explain how you answered it along with your answer - thanks
Answer:
B
Step-by-step explanation:
Because you have to separate the equation. So you get [tex]\frac{2x-4}{3}[/tex]>[tex]\frac{1}{5}[/tex] And [tex]\frac{2x-4}{3}[/tex]<6
Then you have to solve for x so you get x>[tex]\frac{23}{10}[/tex] and x>11
Then you find the intersection so the answer is B

A migrating bird flies 42 miles in 3 hours. How many miles does it fly in 5 hours?
Answer:
70 miles.
Step-by-step explanation:
In this question we are given the speed of the migrating bird. If we remember the definition of speed we will remember that speed is distance the object/body traveled, divided by the time it took the object/body to travel this distance.
Solution:
Firstly we need to find out what distance will the bird travel in 1 hour. We can easily do that science we know the distance it travels in 3 hours. So we just use the property of a fraction that states that if we multiply or divide the denominator and the numerator by the same number we will get a fraction of the same value but written a bit differently. So we divide the numerator and the denominator by 3 and get
[tex]\frac{42 miles}{3 hours}[/tex] = [tex]\frac{14 miles}{1hour}[/tex]
Now we know what distance the bird travels in one hour so we can easily figure how much the bird will travel in 5 hours by multiplying the numerator and the denominator by 5. So we do...
[tex]\frac{14 miles}{1 hour}[/tex] = [tex]\frac{70 miles}{5 hours}[/tex]
And we get that the bird will travel 70 miles in 5 hours.

For the high school's production of "Grease," 315 tickets were sold. The cost of a student ticket, s, was $5; the cost of all other tickets, t, was $8. The total income from ticket sales equaled $2211. The system of equations below can be used to determine the number of each type of ticket sold. s+t=315 55 + 8 = 2211 How many student tickets were sold?
Answer:
103 students tickets were sold
Step-by-step explanation:
103 times $5 = $515
212 times $8 = $1696
$515 + $1696 = $2211
