Answer:
Kim will need to spend 67 minutes on her sixth ride
Step-by-step explanation:
Represent the number of minutes of her sixth ride by m.
Then the average number of minutes is
53 + 43 + 56 + 54 + 45 + m
---------------------------------------- = 53
6
Multiplying both sides of this equation by 6 yields
6(53 + 43 + 56 + 54 + 45 + m)
--------------------------------------------- = 6(53)
6
which simplifies to
251 + m
---------------- = 318
or 251 + m = 318. Subtract 251 from both sides to obtain the value of m:
m = 318 - 251 = 67
Kim will need to spend 67 minutes on her sixth ride to attain an average ride length of 53 minutes.i

Find ordered pairs for y=4x+2
Answer:
(1,6) (2,10) (3,14) etc.
Step-by-step explanation:
You can have infinite number of ordered pairs for this because all you have to do is plug in the x and solve for y. And then you ordered pair is like (x,y) so if you plug in 1 for x, you do y=4*1+2 and that equals 6. So for the x you used 1 and y equaled 6 so an ordered pair can be (1,6) and so on.

9) 1/4
10) 1/8
11) 3/8
Here are the correct answers :)
Answer:
P(2): 1/4
P(1): 1/4
P(4): 1/8
P(3 or 5): 3/8
Step-by-step explanation:
The areas marked 1, 2, and 3 each take up 1/4 of the box. This means that the probability that you will spin the arrow and land in any of those spaces is 1/4 each.
Areas 4 and 5 are HALF the size of areas 1, 2, and 3. This means that areas 4 and 5 are half of 1/4. Half of 1/4 is 1/8.
The word "or" means that you ADD whatever two probabilities they are asking for. In this case, you add areas 3 and 5. So, add 1/4 + 1/8 = 3/8.
(an easy way to add 1/4 to 1/8 is to change 1/4 to 2/8. Then you can add the two areas easily)

there are 8 apples and 11 oranges in a bag. what is the ratio of the apples to oranges?
Answer:
8:11
Step-by-step explanation:
For every 8 apples, there are 11 oranges.
Answer:
8 : 11 = 8 : 11
Step-by-step explanation:
Divide both terms by the GCF, 1:
8 ÷ 1 = 8
11 ÷ 1 = 11
The ratio 8 : 11 cannot be reduced further by dividing both terms by the GCF = 1 :
This ratio is already in lowest terms.
Therefore:
8 : 11 = 8 : 11

Answer:
[tex]x^{\circ}+105^{\circ}=180^{\circ},\\x^{\circ}=z^{\circ},\\180^{\circ}-z^{\circ}=y^{\circ}[/tex]
Step-by-step explanation:
Statement 1:
True - These two angles are supplementary (add up to 180 degrees) because they form one side of a line.
Statement 2:
True - These two angles are vertical angles (opposite to each other at intersection of two lines). All vertical angles are equal.
Statement 3:
False - These two angles are vertical and therefore are equal. Thus, they cannot have a difference of 105.
Statement 4:
False - Two of these angles form one side of a line which is equal to 180 degrees. Since the third angle is greater than zero, they cannot all add up to 180 degrees.
Statement 5:
True - These two angles are supplementary (add up to 180 degrees) because they form one side of a line.
Statement 6:
False - These two angles are supplementary (add up to 180 degrees) because they form one side of a line and therefore cannot be equal to 105.
Answer and Step-by-step explanation:
The answers are:
x + 105 = 180 (Supplementary angles = 180 degrees)
x = z (Vertical angles are congruent)
180 - z = y (Supplementary angles = 180 degrees)

During a walk-a-thon, Noah's time in hours, t, and distance in miles, d, are related by the equation 1/3d=t.
What point on a graph would represent the time it took to walk 15 miles?
The best answer gets brainliest
Answer:
(15, 5)
Step-by-step explanation:
In this equation, the distance in miles (d) would represent the input or x-axis value on a graph, while the time in hours (t) would represent the output or y-axis on a graph. Therefore, we can substitute d for the value of 15 and solve for t to get the point on the graph.
[tex]\frac{1}{3} * 15 = t[/tex]
5 = t
Finally, we see that if d=15 then t=5. This means that this would be represented on a graph as the point (15, 5)

WILL GIVE BRAINLIEST: What is the local minimum value of the function g(x)=x^4-5x^2+4? (Round answer to the nearest hundredth)
Answer:
Step-by-step explanation:
you can find where the first derivative is 0 to find the critical points
g'(x) = ( x^4 -5x^2 +4)' = 4x³-10x
g'(x) =0, make y =0 to find find where g'(x) is 0
4x³-10x =0 , factor 2x
2x(2x²-5)= 0 , each factor must be 0
2x= 0, so x= 0
2x²-5 =0, so x = ±√5/2
we now have 3 critical points -√5/2, 0, and √5/2
make intervals (-∞, -√5/2), (-√5/2, 0) , (0, √5/2) and (√5/2, +∞)
pick a point to test on each interval: -2, -1, 1 and 2 for example, and
calculate g'(x) = 4x³-10x at those points
for x= -2 we have 4(-2)³-10(-2) = -12 , negative number, decrease
for x= -1 we have 4(-1)³-10(-1) =6, positive number, increase
for x= 1 we have 4(1)³-10(1) = -6, negative number, decrease
for x= 2 we have 4(2)³-10(2) = 12, positive number, increase
we went from a decrease to an increase on intervals (-∞, -√5/2), (-√5/2, 0) so x= - √5/2 ≈ -1.58 is a minimum
we went from a decrease to an increase on intervals (0, √5/2), (√5/2, +∞) so
x= √5/2 ≈ 1.58 is a minimum as well

then according to the question , perimeter of rectangle is 2(l+b)then, here perimeter is given so we put it In the place of perimeter ,24.8=2(l+b)then 24.8=2(x+(x+4)) then 24.8=2(2x+4),24.8=4x+8,then after solving this equation you will find your answer8.) Trey and Matt each have a rectangular prism. The base of Trey’s prism is 4 cm by 7 cm and has a height of 12 cm. The base of Matt’s prism is 6 cm by 10 cm and has a height of 3 cm. Whose rectangular prism will require more material to construct?
Answer:
Trey's rectangular prism will require more material to construct.
Explanation:
Trey's rectangular prism's surface area is more than Matt's rectangular prism's surface area.
Matt's prism volume is lower than Trey's prism, therefore Matt’s prism required more material to construct.
What is volume?Volume is defined as the mass of the object per unit density while for geometry it is calculated as profile area multiplied by the length at which that profile is extruded.
Here,
The base of Trey’s prism is 4 cm by 7 cm and has a height of 12 cm.
Volume of Trey's prism = 4 × 7 × 12 = 336 cm³
The base of Matt’s prism is 6 cm by 10 cm and has a height of 3 cm.
Volume of Matt’s prism = 6 × 10 × 3 = 180 cm³
From the above calculation, Matt’s prism required more material to construct.

What is the surface area of the cylinder shown? Use 3.14 for pie. 4cm for the Radius, and 9cm for the height.
==============================================
Work Shown:
SA = 2*pi*r^2 + 2*pi*r*h
SA = 2*3.14*(4)^2 + 2*3.14*4*9
SA = 326.56
Notes:
The answer is approximate. Use more decimal digits of pi to get a more accurate answer (though it will never be exact unless you leave it in terms of pi).The portion 2pi*r^2 is the fact we have two circular bases with area of pi*r^2 each.The portion 2*pi*r*h is the lateral area, or the area around the curved side. If you unfold this portion, as you would maybe a label on a soup can, it has base of 2*pi*r and height h. The base 2pi*r is the circumference of the circle of radius r.Answer:

Step-by-step explanation:
Okay, here it goes:
Where there is a g you insert -2 and where there is an h you insert 5
(2(-2)+9(5)-5)-(6(-2)-4(5)+2)
If two numbers are side-by-side with no other sign between them, you multiply
(-4+45-5)-(6(-2)-4(5)+2)
(-4+45-5)-(-12-20+4)
There is a subtraction sign between these equations. That means you must distribute the negative sign to the equation on the right.
Remember:
Negative × Negative = PositiveNegative × Positive = NegativePositive × Positive = Positive-4+45-5+12+20-4
Now just add them together. I recommend going left to right.

x+5+x+7x-5=180 degree (being the interior angles of a triangle)
9x=180
x=180/9
x=20 degree
Answer:
x° = 20°
Step-by-step explanation:
Sum of angles of triangles = 180°
Therefore,
(x + 5) + (7x - 5) + x = 180
x + 5 + 7x - 5 + x = 180
9x = 180
x = 20
∠M = (x + 5) = 20 + 5 = 25°
∠L = (7x - 5) = 140 - 5 = 135°
∠N = x = 20°
