Step-by-step explanation:
Given the figure below, find the values of x and z.
Answer: z = 107; x = 5
Step-by-step explanation:
z = 107 They are vertically opposite angles, which they are equal.
z + (6x + 43) = 180
1. Plug in 107 for z.
107 + (6x + 43) = 180
2. Get rid of parentheses.
107 + 6x + 43 = 180
3. Sum up the number in the left sides.
6x + 150 = 180
4. Subtract 150 from both sides.
6x = 30
5. Divided 6 from both sides.
x = 5
The speed of an object can be found by dividing the distance traveled by the time it took. It takes Jamal $36$ seconds to skate once around a $500\text{ }\text{m}$ rink. If it takes Tory $40$ seconds to skate the same distance, what is the difference in their speeds?
Answer:
Difference = 13.9 m/s
Step-by-step explanation:
Speed of an object = distance traveled/time taken
Jamal takes 36 seconds to skate 500 m rink. Let his speed is v. So,
[tex]v=\dfrac{500\ m}{36\ s}\\\\=13.89\ m/s[/tex]
Tory takes 40 seconds to skate 500 m rink. Let his speed is v'. So,
[tex]v'=\dfrac{500\ m}{40\ s}\\\\=12.5\ m/s[/tex]
The difference in their speeds,
D = 13.89 - 12.5
= 1.39 m/s
Hence, the difference in their speeds is 13.9 m/s.

for π. Enter your answer in the box.
Answer :
132 cm³.Explanation :
We know,
⠀
[tex]{ \longrightarrow \bf \qquad { { Volume_{(cone) }= \dfrac{1}{3} \pi {r}^{2}h }}}
[/tex]
⠀
Where,
r is the base radius of the cone.h is the height of the cone.⠀
Here,
Radius of the cone is 3 cm .Height of the cone is 14 cm .We will take the value of π as [tex] \sf \: \dfrac{22}{7} [/tex]⠀
Substituting the value in the formula :
⠀
[tex]{ \longrightarrow \sf \qquad { { Volume_{(cone) }= \dfrac{1}{3} \times \dfrac{22}{7} \times {3}^{2} \times 14 }}}[/tex]
⠀
[tex]{ \longrightarrow \sf \qquad { { Volume_{(cone) }= \dfrac{1}{ \cancel3} \times \dfrac{22}{ \cancel7} \times { \cancel9} \times \cancel{14 }}}}[/tex]

Therefore,
The volume of the cone is 132 cm approximately .Question :-
Calculate the Volume of Cone, if the following dimensions are Radius as 3 cm and Height as 14 cm .Answer :-
Volume of Cone is 132 cm .Explanation :-
As per the provided information in the given question, we have been given that the Radius of the Cone is 3 cm . Its Height is given as 14 cm . And, we have been asked to calculate the Volume of the Cone .
For calculating the Volume , we will use the Formula :-
[tex] \bigstar \: \: \: \boxed{ \sf{ \: Volume \: _{Cone} \: = \: \frac{1}{3} \: \pi {r}^{2} h \: }} [/tex]
Where ,

[tex] \dag \: \: \: \sf{Volume \: _{Cone} \: = \: \dfrac{1}{3} \: \times \: \pi \: \times \: {r}^{2} \: \times \: h } [/tex]
[tex] \longmapsto \: \: \sf{Volume \: _{Cone} \: = \: \dfrac{1}{3} \: \times \: \dfrac{22}{7} \: \times \: ( {3})^{2} \: \times \: 14 } \\ [/tex]
[tex] \longmapsto \: \: \sf{Volume \: _{Cone} \: = \: \dfrac{1}{3} \: \times \: \dfrac{22}{7} \: \times \: 9 \: \times \: 14 } \\ [/tex]
[tex] \longmapsto \: \: \sf{Volume \: _{Cone} \: = \: \dfrac {1}{1} \: \times \: \dfrac {22}{1} \: \times \: 3 \: \times \: 2 } [/tex]
[tex] \longmapsto \: \: \sf {Volume \: _{Cone} \: = \: 1 \times \: 22 \: \times \: 3 \: \times \: 2} [/tex]
[tex] \longmapsto \: \: \sf {Volume \: _{Cone} \: = \: 1 \times \: 22 \: \times \: 6} [/tex]
[tex] \longmapsto \: \: \sf {Volume \: _{Cone} \: = \: 22 \: \times \: 6} [/tex]
[tex] \longmapsto \: \: \bf {Volume \: _{Cone} \: = \: 132 \: cm } [/tex]
Hence :-
Volume of Cone = 132 cm .[tex] \underline {\rule {200pt} {4pt}} [/tex]

Step-by-step explanation:
Which equation could be solved using this application of the quadratic formula? PLS HELP
Answer:
d) [tex]2x^2+12x+4=13[/tex]
Step-by-step explanation:
Quadratic formula:
[tex]x=\dfrac{-b\pm\sqrt{b^2-4ac} }{2a}[/tex]
The quadratic formula can be used to solve a quadratic equation in the form [tex]ax^2+bx+c=0[/tex]
From inspection of the given quadratic formula:
a = 2b = 12c = -9Therefore, plugging these values into the general form of the quadratic equation:
[tex]2x^2+12x-9=0[/tex]
If we add 13 to both sides we get:
[tex]2x^2+12x+4=13[/tex]
Answer: D
Step-by-step explanation:
The quadratic formula helps you find the roots of a quadratic function, specifically where the function equals zero. In order for an equation to match the use of the quadratic formula shown, the value of 'b' must be +12. It also demands that 'a' must be +2, and 'c' must be -9. Answer D has all these prerequisites.

To find the y-intercept substitute x as 0
[tex]y = 1 \times {0}^{2} + 7 \times 0 - 5[/tex]
[tex]y = 1 \times 0 + 0 - 5[/tex]
[tex]y = 0 + 0 - 5[/tex]
[tex]y = - 5[/tex]
Thus, The y-intercept is -5...~We know that:
The y-intercept of an equation is the constant. Constants are the numerals in the equation.Finding the y-intercept.
In the equation provided, we can see only one constant.
=> y = 1x² + 7x - 5Thus, the y-intercept is -5.
Which choice shows a reflection across the x-axis?
A) A
B) B
C) C
D) D
Graph (D) indicates a reflection across the x-axis.
What is a transformation?A point is transformed when it is moved from where it was originally to a new location. Translation, rotation, reflection, and dilation are examples of different transformations.
As we know that reflection across the x-axis is defined as reflecting a point across the y = x, the x-coordinate, and y-coordinate places, and the line y = -x is the coordinates (x, -y).
So reflected across the x-axis: f(x) → -f(x),
⇒ (x,y) → (x , -y)
"A" is a y-axis reflection, "B" and "C" are basically points shifting to a different region of the graph, and "D" is a mirror reflection on the x-axis.
Hence, graph (D) shows a reflection across the x-axis.

A car traveled 261 miles on 9 gallons of gas. The same car also traveled 145 miles on 5 gallons of gas. If the ordered pairs for this relationship are (gallons,
distance), what is the slope of the line through these two ordered pairs?
Answer:
slope = 29
Step-by-step explanation:
Given that
the ordered pairs for this relationship are (gallons, distance)
it means on coordinate plane
x represents gallons
y represents distance
thus,
two point on plane will be
A car traveled 261 miles on 9 gallons of gas
miles = 261 ---let it be represented by x1
gallons = 9---let it be represented by y1
(x1,y1) = (9,261)
miles = 145 ---let it be represented by x2
gallons = 5---let it be represented by y2
(x2,y2) = (5,145)
slope of two points (x1,y1) and (x2,y2) is given by
slope = m = (y2-y1)/(x2-x1)
thus, slope of the above ordered pair
m = (145-261)/(5-9) = -116/-4 = 29
Thus, slope of the line through these two ordered pairs is 29.
