Answer:
22.4
Step-by-step explanation:
A car is driving down the road and goes 500 miles in 10 hours.
So,
d = 500 miles = 804672 metres
t = 10 hours = 36000 minutes
∴ v = d ÷ t
v = 804672 ÷ 36000
v = 22.352
∴ v = 22.4 m/s
Thus, His Velociy was 22.4 m/s

a force of 10 newtons acts in a direction 75 above horizontal moving an object 15 meters from (0,0) to (15,0). What is the work done by the force?
a. 2.59 joules
b. 3.88 joules
c. 38.82 joules
d. 150.00 joules
Answer:
150 JoulesStep-by-step explanation:
Step one:
Given data
Force F= 10N
the distance is described by the coordinate = (0,0) to (15,0)
hence the distance = 15m in the x-direction.
Step two:
Required is the work done
we know that work done is expressed as
Wd= Force* Distance
Wd= 10*15
Wd= 150 Joules

4(x + 1) = 34+4
-2x - 3) = 2X-6
6(x + 5) = 6x + 11
5) Intro
Answer:
Equations with one solution: [tex]-2(x-3) = 2x-6[/tex]
Equations with no solution:
[tex]6(x+5) = 6x+11\\5(x-2) = 5x-7[/tex]
Equations with infinite many solutions: [tex]-3(x-4) = -3x+12[/tex]
Step-by-step explanation:
We will solve each equation to see if it has one solution, no solution or infinite many solutions.
An equation where the value of variable can be found has one solution.
An equation with no solution has both sides different.
An equation with infinite solution will have both sides equal after solution(number)
So,
Equation 1:
5(x-2) = 5x-7
[tex]5(x-2) = 5x-7\\5x-10 = 5x-7\\5x-5x = -7+10\\0 = 3[/tex]
As both sides are not equal, equation has no solution.
Equation 2:
[tex]-3(x-4) = -3x+12\\-3x+12 = -3x+12\\-3x+3x = -12+12\\0=0\\[/tex]
As both sides are equal the equation has infinite many solutions.
Equation 3:
[tex]-2(x-3) = 2x-6\\-2x+6 = 2x-6\\-2x-2x = -6-6\\-4x = -12\\\frac{-4x}{-4} = \frac{-12}{-4}\\x = 3[/tex]
As x=3, the equation has only one solution.
Equation 4:
[tex]6(x+5) = 6x+11\\6x+30 = 6x+11\\6x-6x+30 = 11\\30 =11[/tex]
The equation has no solution.
Hence,
Equations with one solution: [tex]-2(x-3) = 2x-6[/tex]
Equations with no solution:
[tex]6(x+5) = 6x+11\\5(x-2) = 5x-7[/tex]
Equations with infinite many solutions: [tex]-3(x-4) = -3x+12[/tex]

Answer:
y = -4x - 6
Step-by-step explanation:
slope-intercept form: y = mx + b
Given: Slope: -4
Point: (-2, 2)
To write an equation in slope-intercept form, we need to know the slope(m) and the y-intercept(b). Since we were given the value of the slope, all we have to do now is find b. To do this, input the given values of m and the point into the equation and solve for b:
y = mx + b
2 = -4(-2) + b
2 = 8 + b
-6 = b
The y-intercept is -6.
Now that we know the slope and the y-intercept, we can write the equation:
y = -4x - 6
in the circle shown, AB is tangent to circle o at point and OC is a radius
Which relationship is true?
Answer:
A. [tex] \overline{OC} \perp \overline{AB} [/tex]
Step-by-step explanation:
According to tangent theorem, a tangent is formed when the radius of a circle is perpendicular to the line, meeting at a point around the circle, such that the tangent line would be perpendicular to the radius of the circle with a center.
Given that [tex] \overline{AB} [/tex] is a tangent of the circle O, at a point C, and [tex] \overline{OC} [/tex] is a radius, therefore, it follows that:
[tex] \overline{OC} \perp \overline{AB} [/tex].
This means the radius of the circle is perpendicular to the tangent formed at point C.

Part B: Explain how you found the measure of angle x by identifying the angle relationships that you used along the transversal. (5 points)
AB and CD are parallel lines, and PQ and PR are transversals which intersect AB at P and CD at Q and R. Angle APQ is labeled as 65 degrees, angle QPR is equal to x, angle PRD is equal to 120 degrees.
Answer:
45 degrees
Step-by-step explanation:
pretty sure
Answer:
x = 55
Step-by-step explanation:
to find angle BPR you would do:
180 - 120 = 60
so BPR is 60°
now to find x you do this:
65 + 60 + x = 180
125 + x = 180
x = 55
Can someone help me on this Proofs problems? It's just number one and two.

Step-by-step explanation:
1. By interior angle sum Postulate of a triangle.
[tex] m\angle a+ m\angle y +m\angle z= 180\degree.... (1)\\\\
m\angle a+ m\angle w +m\angle x= 180\degree.... (2)\\\\[/tex]
From equations (1) & (2), we find:
[tex] m\angle a+ m\angle y +m\angle z= m\angle a+ m\angle w +m\angle x\\\\
m\angle y +m\angle z= m\angle w +m\angle x\\[/tex]
Hence proved
2. In [tex] \triangle PQS, \: \angle QSR [/tex] is exterior angle.
Therefore, by remote interior angle theorem, we have:
[tex] m\angle QPS + m\angle PQS= m\angle QSR\\\\
x + m\angle PQS= 2x\\\\
m\angle PQS= 2x-x\\\\
m\angle PQS = x.... (1)\\\\
m\angle QPS = x.... (given).... (2)\\[/tex]
From equations (1) & (2), we find:
[tex] m\angle PQS = m\angle QPS\\\\
\therefore \angle PQS \cong \angle QPS\\\\
\therefore PS \cong QS\\(sides\: opposite \: to\: congruent \:\angle s) \\\\[/tex]
[tex] \therefore \triangle PQS [/tex] is an isosceles triangle.
Thus proved.

- A rectangular pool has an area of 140 square feet. If the length of the
pool is 16 feet, what is its width?
Answer:
8.75 feet
Step-by-step explanation:
Use the area formula, A = lw, where l is the length and w is the width
Plug in the area and length, and solve for w:
A = lw
140 = 16w
8.75 = w
So, the width is 8.75 feet
Answer:
8.75 ft
Step-by-step explanation:
Use the area formula, A = lw, where l is the length and w is the width
Plug in the area and length, and solve for w:
A = lw
140 = 16w
8.75 = w
So, the width is 8.75 feet

6 = 2(y + 2)
Solve for Y.
Answer:
6=2(y+2)
distributive property
6=2(y)+2(2)
6=2y+4
-4 -4
2=2y
-- --
2 2
divide two in both sides to get y by itself
y=1
Answer:
y = 1
Step-by-step explanation:
6 = 2 (y + 2)
Distribuite:
2 * y = 2y
2 * 2 = 4
2y + 4 = 6
Use additive inverses. The additive inverse of addition is subtraction.
Subtract 4 from both sides:
2y + 4 - 4 = 6 - 4
6 - 4 = 2
2y ÷ 2 = 2 ÷ 2
2y ÷ 2 = y
2 ÷ 2 = 1
To check our answer we multiply how much y is (which is 1) by 2.
2(1) + 4 = 6
2 * 1 = 2
2 + 4 = 6.
Which of the following additional statements would you need to prove these two triangles are similar by SAS similarity?
1. ∠A ≅ ∠D
2. ∠B ≅ ∠E
3. ∠B ≅ ∠F
4. ∠C ≅ ∠F
Answer:
option 1
as the sides were already given, A and D are the only way that the triangle can have SAS.
The option 1 . ∠A ≅ ∠D is correct and needed to apply SAS similarity theorem in this given condition.
What is SAS (side angle side ) similarity theorem for two triangles?The SAS theorem states that if two triangles have a congruent angles and the sides that define the angle are proportional, the two triangles are similar.
Given are two triangles ΔABC and ΔDEF and their sides AB =7 , AC = 12, DE =14, DF = 24
Then AB/ DE = 7/14 = 1/2
and AC / DF = 12/24 = 1/2
∴ AB / DE = AC/ DF
Therefore the sides AB and AC are proportional to DE and DF
And for the application of SAS the angle defined by these pairs must be congruent.
AB and AC defines ∠A and DE and DF defines ∠D
Thus, ∠A must be congruent to ∠D so that SAS can be to applied to make the given triangles similar.
Therefore, option 1. ∠A ≅ ∠D is correct option

Find x no need for explanation I just need answer thanks
Answer:
x = 12 m
Step-by-step explanation:
Length = x m
Width = 3⅔ = 11/3
Area = 44 m²
Area of rectangle = length × width
Plug in the values into the equation
[tex] 44 = x \times \frac{11}{3} [/tex]
[tex] 44 = \frac{11x}{3} [/tex]
Multiply both sides by 3
[tex] 44 \times 3 = \frac{11x}{3} \times 3 [/tex]
[tex] 132 = 11x [/tex]
Divide both sides by 11

The answers to each part is given below.
What is percentage?In mathematics →
a percentage is a number or ratio expressed as a fraction of 100.it is often denoted using the percent sign "%".Given is that you buy a watch for $60.
{a} -Total cost of watch -
{C} = ${60 + (6% of 60)}
{C} = ${60 + (6/100 x 60)}
{C} = $(60 + 3.6}
{C} = $63.6
{b} -New sale price -
{D} = 60 - (15% of 60)
{D} = 60 - (15/100 x 60)
{D} = 60 - 9
{D} = $51
{c} -Total cost of watch including tax -
{CT} = 51 + (6% of 51)
{CT} = 51 + 3.06
{CT} = 54.06
