If u=0, make t the subject of the following equation: s=ut+1/2at^2 Please look at image.
Answer:
[tex]t=\sqrt{\dfrac{2s}{a}}[/tex]
Step-by-step explanation:
The given equation is :
[tex]s=ut+\dfrac{1}{2}at^2[/tex]
Where
s is displacement
u is the initial velocity
a is acceleration
t is time
If u = 0, the above equation become,
[tex]s=\dfrac{1}{2}at^2\\\\t^2=\dfrac{2s}{a}\\\\t=\sqrt{\dfrac{2s}{a}}[/tex]
Hence, the value of t is equal to [tex]\sqrt{\dfrac{2s}{a}}[/tex].
solve this please i just need the top answer thx lol :)
Answer: x+(x+1)+(x+2) = 63
This is because x is the smallest number, so x+1 is the next value up, and x+2 is the value after that. The parenthesis are optional. I used them to separate out the three expressions. We can simplify the left side to 3x+3, which means that equation in bold is the same as 3x+3 = 63. So there are few ways we can form the equation.
You have the correct answers for the other boxes:
20+21+22 = 63
Nice work.
20, 21, 22
Step-by-step explanation:
Let x = the smallest integer of the three consecutive ones
(x + 1) = the next consecutive integer after x
(x + 2) = the next consecutive integer after (x + 1)
The sum of these three should add up to 63 so
x + (x + 1) + (x + 2) = 63
This simplifies to
3x + 3 = 63
Solving for x, we get
x = 20
Therefore, the three consecutive integers whose sum add up to 63 are 20, 21 and 22.

The measure of angle P is ___ degrees, rounded to the nearest hundredth.
Answer:
53°
Step-by-step explanation:
Use sine cosine or tangent (SOHCAHTOA). For this example I'll use sine.
For sine you'd use the equation sin(x)=[tex]\frac{opp}{hyp}[/tex] where x is the missing angle measure
the opposite side from x is 45 cm and the hypotenuse is 53 cm
sin(x)=[tex]\frac{45}{53}[/tex]
then rearrange the equation like this x=[tex]sin^{-1}[/tex]([tex]\frac{45}{53}[/tex])
most graphing calculators should solve it from there if you plug it in, hope this helps! :)

The football team has a total of 50 jerseys. There are 20 medium-sized jerseys. What percent of the jerseys are medium-sized jerseys?
Answer:40%
Step-by-step explanation:20 divided by 50 is 0.4 then multiply that by 100 and get 40
Answer:
Well the equation for this would 50*.20 = ...
The first half of the answer would be 10.
BUT!
You need to subtract 10 from 50.
50-10 = 40!
There you go.

The theater sells two types of tickets: adult tickets for $17 and child tickets for $14.
Last night, the theater sold a total of 238 tickets for a total of $3554. How many adult tickets did the theater sell last night?
Answer:
74 adult tickets
Step-by-step explanation:
Create a system of equations where a is the number of adult tickets and c is the number of child tickets:
a + c = 238
17a + 14c = 3554
Solve by elimination by multiplying the top equation by -14:
-14a - 14c = -3332
17a + 14c = 3554
Add these together, and solve for a:
3a = 222
a = 74
So, 74 adult tickets were sold last night

What is the surface area of a cereal box with a height of 10 inches, a width of 4 ½ inches, and a length of 7 inches?
Answer:
Surface area of a box = 293 inches ²
Step-by-step explanation:
Surface area of a box = 2(lw + lh + hw)
Where,
l = length = 7 inches
w =width = 4 1/2 inches
h = height = 10 inches
Surface area of a box = 2(lw + lh + hw)
= 2(7*4.5 + 7*10 + 10*4.5)
= 2(31.5 + 70 + 45)
= 2(146.5)
= 293 inches ²
Surface area of a box = 293 inches ²

Nathan buys a blender with a listed price of $65. Nathan uses a coupon that provides 20% off. What is the total final price Nathan pays?
Answer:
$52
Step-by-step explanation:
Given data
Price of blender= $65
Coupon = 20%
Let us find the amount of the coupon
=20/100*65
=0.2*65
=$13
Hence the amount of the coupon is $13
The total price Nathan pays is
=65-13
=$52
How does the number 32.4 change when you multiply it by 10 of the power of 2
Which function shown below has the greater rate of change? Explain. (Be sure to include the
rate of change for each in your explanation).
Answer:
Function 1 has a greater rate of change.
Step-by-step explanation:
Function 1 has a rate of change of 3 because 3x is the slope of the line.
Function 2 has a rate of change of 1.5, because when you use rise/run, you get a slope of 3/2.
Function 3 has a rate of change of 2. You use the formula (y2 - y1) / (x2 - x1) to find the slope. I used (0,0) and (1,2). When you plug in 2 for y2, 1 for x2, and 0 for y1 and 0 for x1, you get (2-0) / (1-0) which is 2/1. That equals a slope of 2.
Simplify the product using the distributive property.

Step-by-step explanation:
4h times 4h is 16h^2
4h times -7 is -28h
4h times 6 is 24h

Angle E = 37 degreesAngle G = 37 degrees============================================================
Explanation:
Angles E and G are congruent base angles of the isosceles triangle. The base angles are opposite the congruent sides EF = FG
Let x be the measure of angle E and angle G.
Adding all three angles of any triangle always gets us 180 degrees.
E+F+G = 180
x+106+x = 180
2x+106 = 180
2x = 180-106
2x = 74
x = 74/2
x = 37
Angles E and G are 37 degrees each
Answer:
37 degrees for both angles
Step-by-step explanation:
Any triangle is equal to 180 degrees
therefore, 180 - 106 = 74
74 / 2 = 37
I divided by 2 because you need an amount of 2 angles.
Thus, angles m<E and m<G are both equal to 37 degree
To check:
106 + 37 + 37 = 180
Hope this helped! Have a great day or night wherever you are and stay safe!
if m1=35° and m2=75°, what is m3?
Answer:
m3 should be 70°
all internal angles of a triangle add up to 180
180-35-75 = 70
Answer:
All angles of a triangle add up to 180°.
there m1+m2+m3=180°
35+75+m3=180
110°+m3=180°
m3=180°-110°
m3=70°

help What is the area, in square centimeters, of the trapezoid below?
Answer:
115.15 cm²
Step-by-step explanation:
The area of a trapezoid = 1/2 (b1 + b2)h
Where:
b1 = first base = 8.2 cm
b2 = Second base = 15.3 cm
h = height = 9.8 cm
Hence, Area of the trapezoid =
1/2 (8.2 + 15.3) × 9.8
= 1/2 × (23.5) × 9.8
= 115.15 cm²
Therefore, the area, in square centimeters, of the trapezoid below is 115.15 cm²

A bookstore costs $90 a day to keep open, and it spends $12 for each book that it sells. If each book sells for $18, what is the break-even point for this bookstore?
A. n = 12
B. n = 18
C. n = 15
D. n = 16
Answer:
Total Cost in a day is . Profit function is . And the revenue function is . In a day, bookstore must sell at least 15 books, because of 6n-90=0, in order to make profit.
Step-by-step explanation:
-90
The break-even point for this bookstore is 15, i.e. correct answer is,
C. n = 15.
Here, we have,
given that,
A bookstore costs $90 a day to keep open,
and it spends $12 for each book that it sells.
If each book sells for $18,
now, we know that,
Breakeven quantity = fixed cost / price – variable cost per unit
now, we have,
$90 / (18 - 12)
=$90 / $6
= 15
so, n = 15
Hence, The break-even point for this bookstore is 15, i.e. correct answer is, C. n = 15.
