Step-by-step explanation:
1x = [tex]\frac{d}{dx} \frac{1}{2}x^2[/tex]
[tex]\frac{d}{dx} \frac{1}{2}x^2[/tex]+ [tex]\frac{d}{dx} \frac{1}{2}x^2[/tex]= [tex]\frac{d}{dx} }x^2[/tex]
[tex]\frac{d}{dx} }x^2[/tex] = 2x
2x/x = 2

During a 4-second practice round, one of the Click Bots made only 8 clicks.
Amir claims that the unit rate is 2 clicks per second.
Chloe disagrees. She says it's 0.5 clicks per second.
Who is correct?
Amir or chloe and why ?
Answer:
Step-by-step explanation:
Answer:
amir is correct
Step-by-step explanation:
amir is correct because 8/4 is 2. Therefore if the button is clicked 2 times each second then the button will be clicked 8 times every 4 seconds
y=5x-17 y=x+3 can someone help me with this? thanks
Answer:
x=5, y=8
Step-by-step explanation:
we can use subsitution to solve this so:
5x-17=x+3 since they bot equal y (y=y)
4x-17=13 subtract x from both sides
4x=20 add 17 to both sides
x=5
then, plug in x to solve for y (either equation) :
y = x+3
y = (5) + 3
y = 8

Answer:
The value of zis 23.
Step-by-step explanation:
here,
4x-69=2z-23(opposte angle of parallelogram are equal)
or,4x-2x=-23+69
or,2x=46
or,x=46/2
Therefore x=23#

•A and B
•C and B
• B and E
• E and C
• A and E
• A and C
Answer:
C and B; A and C; E and C;
Step-by-step explanation:
Skew Lines are lines that do not intersect and are not parallel. Skew lines must be in 2 different planes because in 1 plane 2 lines either intersect or are parallel. Assuming that a,b, and e are on the plane in front and c is on the plane in the back we can say that A and B, B and E, and A and E can not be skew lines because they lie on the same plane. This leaves C and B, E and C, and A and C.
Answer:
C and B; E and C; A and C
Step-by-step explanation:

Please answer :D Rearrange the linear equation so that it is in slope-intercept form. Identify the slope (m) and the y-intercept (b). You must show your work for full credit.
x - 4 = 2(y - 3)
Answer:
[tex]y=\frac{1}{2}x+1[/tex]
The slope is 1/2.
The y-intercept is 1.
Step-by-step explanation:
We have:
[tex]x-2=2(y-3)[/tex]
Let’s divide both sides by 2. This gives us:
[tex]\frac{x}{2}-\frac{4}{2}=y-3[/tex]
Simplify:
[tex]\frac{1}{2}x-2=y-3[/tex]
Add 3 to both sides:
[tex]\frac{1}{2}x+1=y[/tex]
Flip:
[tex]y=\frac{1}{2}x+1[/tex]
This is in the slope-intercept form:
[tex]y=mx+b\\[/tex]
Where m is the slope and b is the y-intercept.
Hence, our slope m is 1/2 and our y-intercept b is 1.
You need at least 30 cubic feet of sand to fill a sand box. Each bag contains 2.5 cubic feet of sand. What is the minimum number of bags you need to buy?
Answer:
12 bags of sand
Step-by-step explanation:
The minimum number of sand to fill the sandbox = 30 cubic feet
The volume or quantity of sand per bag is = 2.5 cubic feet
The minimum number of bags needed to fill the sandbox = 30 / 2.5 = 12 bags

63/30= m/50
multiply 63x50
multiply 30x m
now you have
30m = 3150
so you divide
30m/30 and 3150/30
m=105

Can every parallelogram be changed into a rectangle
with equal area? Explain.
Answer:
Every parallelogram can be made into a rectangle, which is why we use the same formula to find the area of a parallelogram and a rectangle.
Step-by-step explanation:
Because the parallelogram and rectangle are composed of the same parts, they necessarily have the same area.

Casey orders 3 pizzas and 2 orders of breadsticks for a total of $29.50. Rachel orders 2 pizzas and 3 orders of breadsticks for a total of $23. How much would it cost to order 5 pizzas and 6 orders of breadsticks?
Answer:
$54.50
Step-by-step explanation:
3 pizzas + 2 breadsticks = $29.50
2 pizzas + 3 breadsticks = $23
5 pizzas + 6 breadsticks = $x
multipy first equation by 3 and second by -2
9 pizzas + 6 breadsticks = $88.50
-4 pizzas -6 breadsticks = $-46
add the equations up, 9-4 pizzas + 6-6 breadsticks = $88.50-46
5 pizzas = $42.50 , divide by 5 both sides
1 pizza = $8.50
Substitute the price of a pizza, 2 pizzas + 3 breadsticks = $23
2*8.50 + 3breadstiks = $23
17 + 3 breadsticks = $23 subtract 17 from both sides so
3 breadsticks = $23 -$17 divide by 3
1 breadstick = 6/3= $2
$5*8.50 for pizzas + $6*2 for breadsticks = $54.50

Jordan's activity tracker showed that when she walked for 12 minutes she took 804 steps. Karen's activity tracker showed that she walked 2,100 steps in 32 minutes. Who was walking at a faster rate?
Given:
Jordan's walked for 12 minutes she took 804 steps.
Karen's walked 2,100 steps in 32 minutes.
To find:
Who was walking at a faster rate?
Solution:
We need to find the unit rate of Jordan and Karen.
[tex]\text{Unit rate}=\dfrac{\text{Total steps}}{\text{Total time}}[/tex]
Unit rate of Jordan,
[tex]\text{Unit rate}=\dfrac{804}{12}[/tex]
[tex]\text{Unit rate}=67[/tex]
Unit rate of Karen,
[tex]\text{Unit rate}=\dfrac{2100}{32}[/tex]
[tex]\text{Unit rate}=65.625[/tex]
Clearly, 67 > 65.625.
Since, unit rate of Jordan is greater, therefore she walked faster.
A flat rectangular piece of aluminum has a perimeter of 62 inches. The length is 15
inches longer than the width. Find the width.
Answer:
So, the required width of rectangular piece of aluminium is 8 inches
Step-by-step explanation:
We are given:
Perimeter of rectangular piece of aluminium = 62 inches
Let width of rectangular piece of aluminium = w
and length of rectangular piece of aluminium = w+15
We need to find width i.e value of x
The formula for finding perimeter of rectangle is: [tex]Perimeter=2(Length+Width)\\[/tex]
Now, Putting values in formula for finding Width w:
[tex]Perimeter=2(Length+Width)\\\\62=2(w+15+w)\\62=2(2w+15)\\62=4w+30\\62-30=4w\\4w=32\\w=\frac{32}{4}\\w=8[/tex]
After solving we get the width of rectangular piece :w = 8
So, the required width of rectangular piece of aluminium is 8 inches

Actual total direct labor $ 655,200 Actual hours worked 37,700 Standard labor-hours allowed for actual output (flexible budget) 36,500 Direct labor price variance $ 23,400 F Actual variable overhead $ 157,120 Standard variable overhead rate per standard direct labor-hour $ 4.20
Answer:
Complete question "Variable overhead is applied based on standard direct labor-hours allowed. Required: Compute the labor and variable overhead price and efficiency variances.
a. Direct labor
Direct labor price variance = (actual rate - standard rate)*actual hrs
(655,200-37700*x) = 23400
x = (655200+23400)/37700
x = 18
Efficiency variance = (Actual hrs - standard hrs allowed)*standard rate
= (37,700 - 36500)*18
= 21600 U
I. Price variance = 23,400 F
II. Efficiency variance = 21,600 U
b. Variable overhead
Price variance = (Actual rate - standard rate)*actual hrs
= (157120 - 37700*4.2)
= 1220 F
Efficiency variance = (Actual hrs - standard hrs allowed)*standard rate
= (37700-36500)*4.2
= 5040 U
I. Price variance = 1,220 F
II. Efficiency variance = 5,040 U
Kiran buys supplies for the school’s greenhouse. He buys 푓 bags of fertilizer and 푝 packages of soil. He pays $5 for each bag of fertilizer and $2 for each package of soil and spends a total of $90. The equation 5푓 +2푝 = 90 describes this relationship. If Kiran solves the equation for 푝, which equation will result?
Answer and explanation:
Given that Kiran buys x bags of fertilizer and y packages of soil
He pays $5 for each bag of fertilizer and pays $2 for each package of soil
He spends a total of $90
So his equation is
5x+2y= $90
If we solve the equation for y(packages of soil)
We would have:
2y=$90-5x
y= $90-5x/2
Therefore Kiran's equation to get number of packages of soil is
y=$90-5x/2
Solve for x and y

Answer:
x = 3
Step-by-step explanation:
7(2 - x) - 5(x - 1) = -6x + 1 (distribute the 7 and the 5)
14 -7x -5x + 5 = -6x + 1 (collect like terms)
-12x + 19 = -6x + 1 (add 12 on both sides)
19 = 6x + 1 (subtract 1 on both sides)
18 = 6x (divide by 6 on both sides)
3 = x
