Answer:
1.192 feet per second
Step-by-step explanation:
convert 4 minutes into seconds
4 times 60
240 seconds
velocity (speed)= distance divided by time
v=286/240
v=1.192
Which choice is equivalent to the expression below?
V-12
A. -24/5
B. 2123
C. -121
D. 231
E. 12 i
Given:
Consider the expression is [tex]\sqrt{-12}[/tex].
To find:
The value of given expression.
Solution:
We have,
[tex]\sqrt{-12}[/tex]
It can be written as
[tex]\sqrt{-12}=\sqrt{-1\times 12}[/tex]
[tex]\sqrt{-12}=\sqrt{-1}\times \sqrt{12}[/tex] [tex][\because \sqrt{ab}=\sqrt{a}\sqrt{b}][/tex]
[tex]\sqrt{-12}=i\times \sqrt{12}[/tex] [tex][\because \sqrt{-1}=i][/tex]
[tex]\sqrt{-12}=\sqrt{12}i[/tex]
Therefore, the value of given expression is [tex]\sqrt{12}i[/tex].
Note: all options are incorrect.
How do you solve this system by elimination? 2x + 4y =8
Answer:
The answer is x=−2y+4
Step-by-step explanation:
1) Add -4y to both sides.
2x+4y+−4y=8+−4y
2x=−4y+8
Step 2: Divide both sides by 2.
2x/2=−4y+8/2
x=−2y+4

Answer:
63 degrees
Step-by-step explanation:
All angles add up to 180
(5x+6) + (4x-6) + (5x-2) = 180
put like terms together
5x+4x+5x + 6-6-2 = 180
14x -2 = 180
add 2 to both sides
14x = 182
divide both sides by 14
x=13
angle G is 5x-2, so if x=13, angle G is 5(13) -2
= 65 -2 = 63 degrees

Solve for x: -2x + 1 = -6
This is a 2-step equation. We will solve it in 2 steps.
[tex]-2x + 1 = -6\\\\-2x = -7\\\\x = \frac{7}{2}[/tex]
The solution for this equation is x = [tex]\frac{7}{2}[/tex].

There are 49 female performers in a dance recital. The ratio of men to women is 2:7. How many men are in the dance recital? There are men in the dance recital.
Answer:
Number of men= 13.99 = 14
Step-by-step explanation:
Giving the following information:
There are 49 female performers in a dance recital. The ratio of men to women is 2:7.
First, we determine the proportion of men to women:
Proportion men to women= 2/7= 0.2857
Now, we calculate the number of men in the show:
Number of men= 0.2857*49
Number of men= 13.99 = 14

Write the following precent as a decimal 1/8%
Answer:
.125
Step-by-step explanation: To convert 1/8 to a decimal, divide the denominator into the numerator. 1 divided by 8 = . 125. To convert the decimal .
Answer: 0.00125
Step-by-step explanation:
percent= decimal×100 therefore, decimal=percent/100 so 1/8 divided by 100 is 0.00125
Sam bought a 7/8 -foot piece of wood to make some small boxes to hold his insect collection. He used 3/16 foot of wood for each box. Which equation can be used to show how many boxes Sam made?
Answer:
Number of small boxes Sam made = Total piece of wood bought / Piece of wood used for each small box
Step-by-step explanation:
Total piece of wood bought = 7/8 foot
Piece of wood used for each small box = 3/16 foot
Number of small boxes Sam made = Total piece of wood bought / Piece of wood used for each small box
= 7/8 foot ÷ 3/16 foot
= 7/8 × 16/3
= 7×16 / 8×3
= 112 / 24
= 4 16/24
= 4 2/3 small boxes
The equation is:
Number of small boxes Sam made = Total piece of wood bought / Piece of wood used for each small box

What is the area of rectangle VWXY?
Answer:
The area of the rectangle VWXY is 52 square units
Step-by-step explanation:
The formula of the area of the rectangle is A = L × W, where
L is the length of the rectangleW is the width of the rectangleIf a line segment has endpoints (x1, y) and (x2, y), then the line segment is horizontal and its length = x2 - x1If a line segment has endpoints (x, y1) and (x, y2), then the line segment is vertical and its length = y2 - y1From the given figure
∵ VWXY is a rectangle
∵ V = (3, -9) and W = (-1, -9)
∵ X = (-1, 4) and Y = (3, 4)
∵ Its length is WX or VY
∴ WX = VY
∵ Its width is VW or XY
∴ VW = XY
→ Let us find its length and its width
∵ Points W and X have the same x-coordinates
∴ y1 = -9 and y2 = 4
→ By using the 4th note above
∴ WX = 4 - -9 = 4 + 9 = 13
∴ L = 13 units
∵ Points X and Y have the same y-coordinates
∴ x1 = -1 and x2 = 3
→ By using the 3rd note above
∴ XY = 3 - -1 = 3 + 1 = 4
∴ W = 4 units
→ By using the formula of the area above
∵ A = 13 × 4
∴ A = 52 square units
∴ The area of the rectangle VWXY is 52 square units

What postulate or theorem can be used to prove that these two triangles are congruent?
PLEASE HELP I REALLY NEED IT!!!
I will give brainliest.
Use the picture
Step-by-step explanation:
The attached figure shows two triangles AOB and MON.
In triangles AOB and MON,
AB = MN (Given )
∠AOB = ∠MON (vertically opposite angles)
∠O = ∠O (common)
∴ ΔAOB ≅ Δ MON (ASA)
Angle-side-angle is the postulate that can be used to prove that two triangles are congruent.

Max was fencing in his rectangular pool area. The length of the pool was (2x -3) feet and the width of the pool was (x + 4) feet. a) Write and simplify an expression for the perimeter of the pool area to be fenced in. Be sure to include the formula!
Answer:
(6x + 2) feet
Step-by-step explanation:
The formula for the perimeter of a rectangle = 2L + 2 W
Where L = Length
W = Width
Hence, the:
The length of the pool was (2x -3) feet and the width of the pool was (x + 4) feet.
The perimeter of the rectangular pool =
2(2x - 3) + 2(x + 4)
= 4x - 6 + 2x + 8
= 4x + 2x - 6 + 8
= (6x + 2) feet
Therefore, an expression for the perimeter of the pool area to be fenced is (6x + 2) feet

If Tony earns five dollars on Monday and five dollars on Tuesday is that a sum of zero? need help I’m in 4th
Answer:
The sum is $10
Step-by-step explanation:
Since Tony got $5 on Monday and $5 on Tuesday, we can add them together by doing 5+5. We can add 5 and 5 together to get a total of $10 that Tony has earned. This means that it isn't a sum of 0 but a sum of 10.
