Answer:
No, Jason did not solve correctly
Step-by-step explanation:
Jason has saved 41% of what he needs to buy a 73$ skateboard.
Jason found out 50% of 70 is the same things as 70 divided by .50= 140. So he has more than enough to purchase the skateboard. Did he solve correctly
Let compare both statements
50% of 70 = 70 ÷ 0.5 (140)
50% × 70 = 140
50/100 × 70 = 140
35 ≠ 140
JASON DID NOT SOLVE CORRECTLY
This is because the left-hand side used the operation of multiplication while the right-hand side used the operation of division.

Good day!
120 students of a hostel food enough for 60 days. if 30 more students joined after 15 days. how long will the remaining food last.
Answer:
24 days
Step-by-step explanation:
120 students =30 days
120+30 =150 students
MORE/LESS METHOD
120 students (a) : 30 days(y)
150 students (b) : x
Find the value of x using the formula: a/b × y
If you think the value of x will be more than y then the bigger number will be the numerator. If u think x will be less, then the smaller number will be in the numerator.
I predict that x will be less than y
THEREFORE... 120/150 ×30
= 24 days
Step-by-step explanation:
ans is simple so plz tell me that it is right or wrong and also it is helpful to u or not

300$ at 6% for 2 yrs what is the simple interest
Answer:
Simple interest after 2 year = $36
Step-by-step explanation:
Given:
Amount invested = $300
Number of year amount invested = 2 year
Rate of interest per year = 6% = 6/100 = 0.06
Find:
Simple interest after 2 year
Computation:
Simple interest formula;
Simple interest = [Amount invested][Rate of interest][Number of year]
Simple interest after 2 year = [300][0.06][2]
Simple interest after 2 year = [18][2]
Simple interest after 2 year = $36

Write an expression for the nth term of this sequence.
Answer:
aₙ = 5n + 1Step-by-step explanation:
11 - 6 = 5 , 16 - 11 = 5 , 21 - 16 = 5
So, it's atithmetic formula with common difference os 5
[tex]a_n = a_1+d(n-1)\\\\a_1=6\\d=5\\\\a_n=6+5(n-1)\\\\a_n=6 +5n-5\\\\a_n = 5n+1[/tex]

AREA OF A TRAPEZOID PLEASE HELP
Please answer this question.
See picture attached.
Just question C please.
Answer:
Diagram B
Step-by-step explanation:
Diagram A makes sense to have a line of best fit because there is a common amount of data for where the next points probably will be. The points are close to the line of best fit, and there are pretty much an even amount of points on each side of the line. So, Diagram A’s line of best fit makes sense.
Diagram C makes sense to have a line of best fit because about the line, all the points are right next to it, and the line of best fit gives a nice representation of the data. So, Diagram C’s line of best fit makes sense.
For Diagram B, all of the points all scattered across the graph and none of them are close to the line of best fit, and a line a best fit is usually made to make an estimat of where the data will be, but for example, the point (20,90) is nowhere near the line of best fit. So, Diagram B’s line of best fit should not have been drawn.
If a cone has a height of 8 inches and a side measurement of 10 inches, what is the radius of its base?
Answer:
The radius of its base is 6 inches
Step-by-step explanation:
The radius of the base of a cone r , the slant height of the cone l and the height of the cone h forms a right triangle, with the slant height being the hypotenuse of the right triangle
Mathematically, since we have a right triangle, we can find the radius of the base by the use of Pythagoras’ theorem
According to Pythagoras’ theorem; the square of the hypotenuse equals the sum of the squares of the two other sides
Thus,
l^2 = r^2 + h^2
l = 10 inches
r = ?
h = 8 inches
10^2 = r^2 + 8^2
100 = r^2 + 64
r^2 = 100-64
r^2 = 36
r = √(36)
r = 6 inches

Which of the following constants can be added to x^2- 3x to form a perfect square trinomlal?
A. 2 1/4
B. 1 1/2
C. 4 1/2
Answer:
A 21/4
Step-by-step explanation:
When forming a perfect square trinomial you need to "complete the square".
All of the steps to completing the square when solving an equation:
1. The leading coefficient must be 1.
2. Divide b by 2.
3. Square (b/2)
4. Add (b/2)^2 to both sides to keep the polynomial balanced.
5. You can now write the perfect square trinomial and solve.
x^2 - 3x
-3/2
(-3/2)^2 = 9/4 = 2 1/4
Sam kicks a ball from the ground with a starting velocity of 32 feet per second. The ball soars into the air, arcs down with parabolic motion, and lands back on the ground. Write an equation to describe the height of the ball as a function of time, using h(t)=-16t^2+vt+s. PLS HELP!!!!!!
Answer:
The function that describes the height of the ball in time is [tex]h(t) = 32\cdot t -16.087\cdot t^{2}[/tex].
Step-by-step explanation:
Let suppose that ball experiments a free fall motion, which means that the ball is accelerated because of gravity and gravitational acceleration can be considered constant since height reached by the object is too small in comparison with the radius of the Earth. Therefore, we can assume that ball is accelerated uniformly.
Hence, the kinematic formula for the height of the ball ([tex]h(t)[/tex]), in feet, is described below:
[tex]h(t) = s + v\cdot t + \frac{1}{2}\cdot g \cdot t^{2}[/tex] (1)
Where:
[tex]s[/tex] - Initial height with respect to the ground, in feet.
[tex]v[/tex] - Initial velocity, in feet per second.
[tex]t[/tex] - Time, in seconds.
[tex]g[/tex] - Gravitational acceleration, in feet per square second.
If we know that [tex]s = 0\,ft[/tex], [tex]v = 32\,\frac{ft}{s^{2}}[/tex] and [tex]g = -32.174\,\frac{ft}{s^{2}}[/tex], then the function that describes the height of the ball in time is:
[tex]h(t) = 32\cdot t -16.087\cdot t^{2}[/tex] (2)

A motorist takes 80 minutes to travel 120km. find his speed
Answer: 90km/hour
Step-by-step explanation:
The formula for speed is given as:
= Distance / Time
where,
Distance = 120km
Time = 80 minutes = 80/60 = 1 1/3 hours
Speed = Distance / Time
= 120 / 1 1/3
= 120 / 4/3
= 120 × 3/4
= 90km/hour
The speed is 90km/hour.
