Select the two values of x that are roots of this equation.
Answer:
B and DStep-by-step explanation:
Solve the equation by completing a square:
x² + 2x - 6 = 0x² + 2x + 1 - 7 = 0(x + 1)² = 7x + 1 = ±√7x = -1 ± √7Correct choice:
B and D$495? Rounded to the nearest cent
Answer:
See the explanation
Step-by-step explanation:
Given data
The Given figure is already a whole number

Kenney High School’s swimming pool is 25 yards long. The pool has 8 lanes, each of
which is 3 yards wide. The pool is filled to a depth of 6 feet.
a. What are the length and width of the pool in terms of feet? (4 points)
Length: __________ ft.
Width: __________ ft.
b. How many cubic feet of water are in the pool? (3 points)
Volume: __________ ft3
c. If one cubic foot contains about 7.5 gallons, how many gallons of water are in
the pool? (3 points)
Water: __________ gallons
Answer:
Length = 75 ft
Width = 72 feet
Volume = 32,400 ft3
Water is around 242,998 gallons
Step-by-step explanation:
Just convert the yards to feet
25 yards long = 75 ft in length
8 lanes * 3 yards wide = 24 yards = 72 feet wide
And then for the volume, since it's a swimming pool, the formula will be l*w*h, and if we plug in the numbers (75 * 72 * 6 (it's 6 because they said the depth was six and in a pool the depth = height)) and that'll equal 32,400 ft to the third power
For the water, we just have to multiply the volume by 7.5 gallons by converting 7.5 gallons to feet, and then multiplying that by the volume, and then converting that to feet, and the final answer is about 242,998 gallons
Answer:
Length; 75 ft
Width; 72 feet
Volume; 32,400
Water is around 243k gallons

Mary simplified the math expression below. The steps that she took are shown. Which is the line where Mary first made her mistake. Line A: – 6 + 9 Line B: [8 + 5 x 3] – 6 + 9 Line C: – 6 + 9 Line D: 23 – 6 + 9 Line E: 23 – 15 Line F: 8
Answer:
Line E
Step-by-step explanation:
Given
The instructions in the question
Required
The first line of mistake
The question has missing details, as the original expression is not given;
Reading through the question, one can observe that, Mary made a mistake at Line E.
The expression on D is:
[tex]23 - 6 + 9[/tex]
The expression on E is:
[tex]23 - 15[/tex]
The actual result of D is:
[tex]23 - 6 + 9 = 23 + 3[/tex]
not
[tex]23 - 15[/tex]
Because:
[tex]-6 + 9 = 3[/tex]
[tex]-6 + 9 \ne 15[/tex]
With the available information, we can conclude that Mary's first mistake is at line E
If you horizontally stretch the quadratic parent function, f(x) = X^2 by a factor
of 5, what is the equation of the new function?
9514 1404 393
Answer:
g(x) = x^2/25
Step-by-step explanation:
For a horizontal stretch by a factor of k, x is replaced by x/k.
g(x) = f(x/5) = (x/5)^2 = x^2/25
The new function is ...
g(x) = x^2/25

Ok my question says "destiny and carla had a total of 3 gallons of paint to share for a project they had 1 gallon each yellow blue and red paint destiny used 3/8 gallon of yellow paint 1/2 of blue paint 1/4 of red paint carla used 1/4 of yellow 3/8 of blue and 1/4 of red then part a ask how much more paint in gallons did destiny use than carly
Answer: 1/4
Step-by-step explanation:
Since Destiny used 3/8 gallon of yellow paint, 1/2 of blue paint and 1/4 of red paint, the total paint used will be:
= ⅜ + ½ + ¼
= 3/8 + 4/8 + 2/8
= 9/8
= 1 1/8
Carla used 1/4 of yellow, 3/8 of blue and 1/4 of red. The total paint used will be:
= 1/4 + 3/8 + 1/4
= 2/8 + 3/8 + 2/8
= 7/8
The numybe of paint that Destiny use more than Carla will be:
= 1 1/8 - 7/8
= 2/8
= 1/4
Destiny used 1/4 paint more than Carla
Team A is located on the south bank of a river. Teams B and C are located on the north bank. The angle formed from Team C to Team A is S 20o W. Team C is 45 feet due west of Team B and 25 feet from Team A. How far is Team A from Team B?
Answer:
Step-by-step explanation:
Given :
Using cosine rule :
c² = a² + b² - 2abCosC
c² = 45² + 25² - 2(45)(25) - cos70
c² = 2650 - 2250 * - 0.3420201
c² = 2650 + 769.54532
c² = 3419.5453
c = sqrt(3419.5453)
c = 58.476
c = 58.5 feets
Helppppp distance time graphhhhhh
Answer:
Ralph walked to Sherwood at a constant speed.
Step-by-step explanation:
Any horizontal lines on a distance time graph represent a moment where you are still, so that rules out graph 4 and graph 3. Because Ralph is at a constant speed, the gradient of the line won’t change, meaning the answer has to be Ralph walked to Sherwood at a constant speed.
FIND THE SURFACE AREA. I WILL MARK YOU A BRAINLEST IF THE ANSWER IS RIGHT
Answer:
SA= 222cm ^2
Step-by-step explanation:
Surface area of the prism = (Perimeter of the base of the prism) × height + 2(area of the base)
Perimeter of the base = 5 + 3 + 2 + 2 + 2 + 3 + 5 + 8
= 30
Area of the base = 8×5 - 2×2 = 36 cm²
Surface area of the prism = 30×5 + 2×(36)= 222 cm²

Find the area of the triangle.
14 m
18 m
Answer:
126
Step-by-step explanation:
trust
Answer:
if your base is 14 and your height is 18 or the other way around then its:
14 x 18 = 252
252 divided by 2 = 126
Step-by-step explanation:
Formula of a triangle:
BH x 1/2 (basically dividing by 2)
B is your base which is the length on the bottom of the triangle and the height is the line that is put in between the triangle. You multiply those then divide by 2 since your multiply 2 with it.
consider the following equations: -x-y=1 y=x+3 if the two equations are graphed, at what point do the lines representing the two equations intersect? (-1,2) (-2,1) (1,-2) (2,-1)
Answer:
(-2, 1)
Step-by-step explanation:
consider the following equations: -x-y=1 y=x+3
For the lines to intersect, the values must be the same
-x-y=1
x + y = -1
y = -x - 1
Equating the y values
-x - 1 = x+ 3
-x-x = 3 + 1
-2x = 4
x = 4/-2
x = -2
Substitute x = -2 into y = x+3
y = -2 + 3
y = 1
Hence the required coordinate is (-2, 1)

How much ribbon is needed to go down both sides of the suitcase
diagonally? (Hint: Draw a picture and add both diagonals together.)
Answer:
60in
Step-by-step explanation:
Given data
Length= 24 in
Width = 18 in
Diagonally, we need to find using the Pythagoras theorem
D^2= L^2+W^2
D^2= 24^2+18^2
D^2= 576+324
D^2= 900
Square both sides
D= √900
D= 30 in
For both sides
=30*2= 60in

Answer:
A. (-4, -4)
Step-by-step explanation:
According to the word problem, a dilation of (0.75x, 0.75y) is applied to a triangle.
This means the original coordinates were enlarged/multiplied by 0.75.
We can multiply the coordinates at the bottom by 0.75 to see if we get any of the resulting images' coordinates.
OR
We could divide the resulting images' coordinates by 0.75 to see if we get any of the answers on the bottom.
For instance,
(-3, -3)
-3 / 0.75 = -4 (x-coordinate)
-3 / 0.75 = -4 (y-coordinate)
This means (-4, -4) were the original coordinates of (-3, -3) before the dilation of 0.75.
