Find three consecutive odd integers such that twice the sum of the second and the third is 43 more than three times the first
Answer: 31, 33, and 35
Step-by-step explanation:
Let’s set up a model for an odd integer: 2x+1. This number has to be odd because it’s an even number plus 1. 3 consecutive days numbers would be 2x+1, 2x+3, and 2-+5. Now we can set up the equations.
2(2x+3+2x+5)=43+3(2x+1)
Simplify:
4x+6+4x+10=43+6x+3
8x+16=6x+46
2x=30
x=15
Now put that back into our original number expressions:
2(15)+1, 2(15)+3, 2(15)+5

A child pushes a toy car with a force of
5.25 N a distance of 6.5 m. The car rolls
for a total distance of 32 m. How much
work is done on the toy car?
The work is done on the toy car is 164.4 J .
How to calculate work done?We are aware that the definition of work is the multiplication of the magnitude of the displacement (d) and the component of the force acting in the displacement direction.
When an object moves over a distance while being applied with force, the work is considered to have been completed.
Three categories can be used to classify the type of labor performed. Positive work, negative work, and zero work are the three types. The angle between force and displacement determines the kind of work that is done. Positive work is defined as any work that causes an object to move in the direction of the applied force.
Given ,
Work = force * distance
Force = 5.2 N
Distance = 32 m
So ,
Work = 5.2 * 32
= 166. 4 J
Therefore the work is done is 164.4 J

How long does it take General Nanisca and the Agojie warriors to get
to the Oyo Empire if they are traveling 23 kilometers per sec to miles per hour?
The given speed in kilometers per sec to miles per hour is 51449.534 mph.
Given that, the Oyo Empire if they are traveling 23 kilometers per sec.
What is the speed?The speed formula can be defined as the rate at which an object covers some distance. Speed can be measured as the distance travelled by a body in a given period of time. The SI unit of speed is m/s.
Now, the conversion of kilometers per sec to miles per hour is as follows:
To convert a kilometer per second measurement to a mile per hour measurement, divide the speed by the conversion ratio.
Thus, mph = km/s ÷ 0.00044704
Now, 23/0.00044704
= 51449.534 miles per hour
Hence, the given speed in kilometers per sec to miles per hour is 51449.534 mph.

[tex]\begin{gathered} x+60-60\leq221-60, \\ x=161. \end{gathered}[/tex]Therefore, at most, you can weigh 161 pounds.
Answer: [tex]x+60\leq221,\text{ at most 161 pounds.}[/tex]Use the quadratic formula to find both solutions to the quadratic equation
given below.
2x^2+ 3x-5 =0
Answer:
X would be -5/2 and 1
Step-by-step explanation:
The quadratic formula is (-b±√(b^2-4ac))/2a. By substituting the values in, we get the expression (-3±√(3^2-4(2)(-5))/2(2). By Simplifying, we get (-3±√(9+40))/4. More simplification: (-3±√(49))/4. Even more simplification: (-3±7)/4. The expression now splits into two parts, (-3-7)/4, and (-3+7)/4. The first expression becomes -10/4, which simplified is -5/2. The second expression becomes 4/4, which simplifies to 1. Therefore, your answers are x=1, -5/2.

An angle is formed when two straight lines or rays meet at a common endpoint. The common point of contact is called the vertex of an angle.
We have a geometrical figure and a statement describing it.
The given statement is -
When the measure of ∠4 is 120°, the measure of ∠1 is 60.
We have ∠4 = ∠1 = 120° {vertically opposite angles}

a, b, c being the sides, A, B, C being the opposing angles of the sides.
and remember, the sum of all angles in a triangle is 180°.
so,
JL/sin(90) = KL/sin(72)
JL/1 = KL/sin(72)
KL = JL × sin(72) = 10 × 0.951056516... =

JK/sin(L) = JL/sin(90) = JL
