Answer:
h = 6.5 feet
Step-by-step explanation:
The height of the frog as a function of time is given by :
[tex]h= -0.5t^2 +3t+2[/tex] .....(1)
We need to find the maximum height reached by the frog. We can find it as follows :
Put [tex]\dfrac{dh}{dt}=0[/tex]
So,
[tex]\dfrac{d}{dt}(-0.5t^2 +3t+2)=0\\\\-t+3=0\\\\t=3[/tex]
Put t = 3 in equation (1).
[tex]h= -0.5(3)^2 +3(3)+2\\\\h=6.5\ feet[/tex]
So, the maximum height is 6.5 feet.

The sum of two numbers is 48. The second number is twice the first
Write and solve a system of equations to find the numbers.
Answer:
The equations are
X + Y = 48 ----Eq (1)
Y = 2 X -----Eq (2)
Solution of the equations and the two number are
X = 16, Y = 32
Step-by-step explanation:
Let the two numbers be X and Y
Given -
The sum of two numbers is 48.
Thus, X + Y = 48 ----Eq (1)
The second number is twice the first
Thus, Y = 2 X -----Eq (2)
Substituting the value of Y in equation (1), we get -
X + 2X = 48
3 X = 48
X = 16
Y = 2 X = 32

There are 244 seventh grade students. The number of students enrolled in P.E. Is 8 fewer than three times the number of students enrolled in health
Answer:
No. of students enrolled in Health = 63
No. of students enrolled in P.E. = 181
Step-by-step explanation:
Given,
Total students in grade seven = 244 students
A.T.Q.
Let the number of students enrolled in Health be x
so, The number of students enrolled in P.E. = 3x - 8
As we know,
x + (3x - 8) = 244
4x = 244 + 8
x = 252/4
x = 63
Thus, the number of students enrolled in Health = 63
The number of students enrolled in P.E. = 3x - 8
= 3 * 63 - 8
= 189 - 8
= 181 students

4/5 divided by 2/7 in simplest form
Answer:
2 4/5
Step-by-step explanation:
4/5 divided by 2/7 is 2.8. 2.8 in the form of a fraction is 2 4/5.
The fraction 4/5 divided by 2/7 in the simplest form, is 14/5.
Given that, (4/5) divided by (2/7).
To divide fractions, multiply the first fraction by the reciprocal of the second fraction
Let a, b, c and d be real numbers. Divide a fraction (a/b) by another fraction (c/d), we can multiply the first fraction by the reciprocal of the second fraction.
The reciprocal of a fraction is obtained by swapping the numerator and denominator. So, the reciprocal of (c/d) is (d/c).
To divide (a/b) by (c/d), multiply the first fraction by the reciprocal of the second fraction:
(a/b) ÷ (c/d) = (a/b) x (d/c)
Multiplying the numerators and denominators:
(ad) / (bc)
Therefore, the result of (a/b) divided by (c/d) is (ad) / (bc).
To simplify this expression, and multiply the first fraction by the reciprocal of the second fraction:
(4/5) x (7/2)
Multiplying the numerators and denominators:
(4 x 7) / (5 x 2)
Simplifying the numerator and denominator:
28 / 10
To further simplify the fraction, and divide both the numerator and denominator by their greatest common divisor, which is 2:
28 ÷ 2 / 10 ÷ 2
This gives us:
14 / 5
Therefore, the fraction 4/5 divided by 2/7, in the simplest form, is 14/5.

The marked price of a radio is Sh. 12600. If the shopkeeper can allow a discount of 15% on the marked price and still make a profit of 25%.At what price did the shopkeeper buy the radio?
Answer:
13388
Step-by-step explanation:
12600 will be 100% so we want to get at what price its sold when there is a 15%dicount
So will minus 15% from the 100% of the Mp
100%-15%=85%
so if 100%=12600
what about 85%=?
we crossmultiply
85%×12600/100%=10710
so10710 is what the radio will be sold if a 15% dicount is given but we want to get wat price the shopkeeper got in that he made a profit of25%
so if 100%=10710
what about 125%
125%×10710/100%=13387.5 which is 13388/=

Answer:
15
Step-by-step explanation:
the height of the person is y = 6 and the distance from the ladder is also 6 = x. To find the angle formed by the ladder we use [tex]arctan(\frac{y}{x})[/tex] which in this case is
[tex]arctan\frac{6}{6} = arctan(1)\\= 45 degrees[/tex]
now we know that the person is 9 feet away from wall and 6 feet away from the ladder so the total x distance is 9+6 = 15 = x
to find y we use tan(45) = [tex]\frac{y}{x}[/tex]
multiply both sides by x = 15 and simplify to get y = 15

Answer:
1824 in.
Step-by-step explanation:
First find the area of the two shapes you split that are the rectangle and triangle:
Rectangle Area:
48 * 32 = 1536
Area- 1536 in.
Triangle Area:
48 * 12 * 1/2
or
48 * 12 divided by 2
= 288 in.
Now add the two areas up:
1536 + 288 = 1824 in.
Answer:
1824
Step-by-step explanation:
I assume you want to find the area of the shape. So in order to find the area of the triangle it is height times base than divide it by 2 which looks like this
(12*48)/2 which equals 576
than to find the area of the rectangle it is height times width which is
48*32 which equals 1536
add them together and you get 1824
Which angle is congruent to <4 <1<2<5<8
Answer:
The angle that will be congruent to angle 4 is :
Angle 1
Step-by-step explanation:
It is given that:
angle 4 and angle 5 are complements.
Also, angle 1 and angle 5 are complements.
Congruent complementary Theorem--
It states that if two angles are complementary to the same angle, then the two angles are congruent to each other.
Here both angle 1 and angle 4 are complementary to the same angle i.e. angle 5.
Two angles are supplementary. One angle measures 132 degrees. Find the measure of the other angle.
Answer:
48 degrees
Step-by-step explanation:
Supplementary angles add up to 180 degrees.
If one angle is 132 degrees, the other must be 48 degrees.
